https://en.wikipedia.org/wiki/Karlis%20Zalts | Karlis Zalts (10 March 1885 – 1953) was a Latvian mathematician with wide-ranging interests in topics such as mechanical calculators, statistics and nomography as well as folklore, education, and philosophy. His publications on folklore prevented him from publishing after 1946 by the Soviet Union.
Biography and education
Karlis Zalts studied at the Real Gymnasium in Jelgava southwest of Riga and graduated in 1904 and then went to the Ukraine to study engineering at the Kiev Polytechnic Institute. After graduating in 1912 he continued on there to teach. After Latvia became an independent country in 1918 Zalts decided to return to Latvia in 1921 with an appointment at the University of Latvia in Riga. To teach mathematics to engineering students until 1938.
In 1928 he wanted to do mathematical research so he went back to school to graduate in mathematics in 1937 with a master's degree in nomography. He continued on to teach mathematics.
The University of Latvia stayed in operation during the Second World War and Zalts started his research towards his thesis. He was awarded his doctorate in February 1944 for his thesis on the geometry of deformations.
Prisoner of war and troubles after the war
The Germans overran Latvia and Zalts was forced to go to Dresden and work at an optical equipment plant to develop optical devices for the German military.
When the Russians captured the plant on 1 May 1945 he became an interpreter for the Russians until 1 September 1945 when he was relocated to Moscow to be forced to be scientific consultant for the Special Construction Bureau. Finally on 16 March 1946 he was able to return to Riga.
Trying to get back to his life in Latvia he worked at the university library and returned to teaching again in the Faculty of Engineering Sciences.
Zalts was just about to be appointed to the new Institutes of the Latvian Academy of Sciences but Soviet background checks found his publications on folklore, education, and philosophy from the 1920s and 1930s.
The Soviets also did not appreciate his many contributions to the Latvian Encyclopedia as this had been banned by the USSR in their desire to create one nation. Zalts now became an "unwelcome person" and while he could continue to teach mathematics to engineers he was never allowed to publish, attend conferences or be promoted at the university.
Works
Zalts was a polyglot and had many wide-ranging interests in topics such as in mechanical calculators, statistics and nomography as well as folklore, education, and philosophy.

https://en.wikipedia.org/wiki/Volodymyr%20Levytsky | Volodymyr Levytsky (31 December 1872 – 13 August 1956) was a Ukrainian mathematician who taught mathematics and studied functions of a complex variable.
Biography and education
Volodymyr Levytsky finished his doctorate at the University of Lviv in 1901 and went on to teach mathematics and physics at high schools.
After the First World War Ukrainian students were not allowed to enrol at the University and in 1920 Ukrainian professors were also banned leaving only Polish lecturers.
As a result, the Ukrainian students set up an underground university at the University in July 1921. From the beginning Levytsky taught mathematics at this new underground university for a few years until it was forced to close in 1925.
Levytsky was the head of the mathematics-physics section of the Shevchenko Scientific Society in Lviv and was the President of the Society from 1931 to 1935 as well as its editor of the Journal. Just before the outbreak of the war until his death in 1956, Levytsky taught at the Lviv Pedagogical Institute.
Works
Levytsky concentrated on functions of a complex variable and the application of mathematics to theoretical physics.
The first mathematical paper in Ukrainian was written by Levytsky as well as being an editor of the first Ukrainian mathematical journal. He brought mathematics and physical and chemical terms to the Ukrainian language through his efforts at the Shevchenko Scientific Society in Lviv. During his short time at the Lviv (Underground) Ukrainian University he produced important papers on the history of mathematics.

https://en.wikipedia.org/wiki/Ernests%20Fogels | Ernests Fogels (12 October 1910 – 22 February 1985) was a Latvian mathematician who specialized in number theory. Fogels discovered new proofs of the Gauss-Dirichlet formula on the number of classes of positively definite quadratic forms and of the de la Vallée-Poussin formula for the asymptotic location of prime numbers in an arithmetic progression.
Life
Fogels was born on 12 October 1910 in Lidzibas, Nigrande, Saldus, Latvia. He discovered his interests in mathematics when attending the Second Gymnasium in Riga.
In 1928 E. Fogels entered the Faculty of Mathematics and Natural Sciences of University of Latvia. After graduating in 1933, he was invited in 1935 to join this university to lecture in algebra and number theory and did research on Diophantine equations. At the end of 1938 he went to University of Cambridge, England to work under the supervision of Albert E. Ingham to help improving the estimate of the difference between two consecutive primes. World war II broke out after Fogels had returned to Latvia in 1939. In 1940, E. Fogels was appointed associate professor at University of Latvia.
In 1947 he defended his PhD thesis on the sequences of asymptotically uniformly distributed numbers and went to work at the newly formed Institute of Physics and Mathematics of the Academy of Sciences of the Latvian SSR as a research fellow. In 1950 he started working at the Riga Pedagogical Institute where he had practically no time for research. In 1961 he became a research fellow at the Radioastrophysical Observatory of the Academy of Sciences of the Latvian SSR. His research focused on the density of zeros of different zeta-functions, on the distribution of primes in arithmetical progressions, on various algebraic fields and on binary and ternary quadratic forms.
Fogels retired in 1966 but continued his scientific work with research on the Hecke's L-functions, prime ideals and the Riemann hypothesis until his death on 22 February 1985 in Latvia.

https://en.wikipedia.org/wiki/GNRS%20conjecture | In theoretical computer science and metric geometry, the GNRS conjecture connects the theory of graph minors, the stretch factor of embeddings, and the approximation ratio of multi-commodity flow problems. It is named after Anupam Gupta, Ilan Newman, Yuri Rabinovich, and Alistair Sinclair, who formulated it in 2004.
Formulation
One formulation of the conjecture involves embeddings of the shortest path distances of weighted undirected graphs into spaces, real vector spaces in which the distance between two vectors is the sum of their coordinate differences. If an embedding maps all pairs of vertices with distance to pairs of vectors with distance in the range then its stretch factor or distortion is the ratio ; an isometry has stretch factor one, and all other embeddings have greater stretch factor.
The graphs that have an embedding with at most a given distortion are closed under graph minor operations, operations that delete vertices or edges from a graph or contract some of its edges. The GNRS conjecture states that, conversely, every minor-closed family of graphs, other than the family of all graphs, can be embedded into an space with bounded distortion. That is, the distortion of graphs in the family is bounded by a constant that depends on the family but not on the individual graphs. For instance, the planar graphs are closed under minors. Therefore, it would follow from the GNRS conjecture that the planar graphs have bounded distortion.
An alternative formulation involves analogues of the max-flow min-cut theorem for undirected multi-commodity flow problems. The ratio of the maximum flow to the minimum cut, in such problems, is known as the flow-cut gap. The largest flow-cut gap that a flow problem can have on a given graph equals the distortion of the optimal embedding of the graph. Therefore, the GNRS conjecture can be rephrased as stating that the minor-closed families of graphs have bounded flow-cut gap.
Related results
Arbitrary -vertex graphs (indeed, arbitrary -point metric spaces) have embeddings with distortion . Some graphs have logarithmic flow-cut gap, and in particular this is true for a multicommodity flow with every pair of vertices having equal demand on a bounded-degree expander graph. Therefore, this logarithmic bound on the distortion of arbitrary graphs is tight. Planar graphs can be embedded with smaller distortion, .
Although the GNRS conjecture remains unsolved, it has been proven for some minor-closed graph families that bounded-distortion embeddings exist. These include the series–parallel graphs and the graphs of bounded circuit rank, the graphs of bounded pathwidth, the 2-clique-sums of graphs of bounded size, and the -outerplanar graphs.
In contrast to the behavior of metric embeddings into spaces, every finite metric space has embeddings into with stretch arbitrarily close to one by the Johnson–Lindenstrauss lemma, and into spaces with stretch exactly one by the tight span construction.

https://en.wikipedia.org/wiki/Louise%20Petr%C3%A9n-Overton | Hedvig Louise Beata Petrén-Overton (August 12, 1880 – January 14, 1977) was a Swedish mathematician, the first woman in Sweden with a doctorate in mathematics.
Early life and education
Louise Petrén was one of twelve children of the vicar of Halmstad. Her father had earned a doctorate in mathematics in 1850, and her great-uncle had been a professor of mathematics at Lund University.
One of her brothers was physician and researcher Karl Anders Petrén.
With two older sisters doing the housework, she was left free to concentrate on her studies.
As a child, ill with scarlet fever, she told her family that she would not go to heaven unless she could bring her mathematics books there.
She earned an education certificate through private tutoring in 1899,
and earned a bachelor's degree at Lund University in 1902,
as one of roughly a dozen women at the university and the only one in the sciences. She earned a licenciate in 1910 and defended her doctorate at Lund in 1911, with the dissertation Extension de la méthode de Laplace aux équations.
Contributions
Nail H. Ibragimov writes that Petrén "made a profound contribution to the constructive integration theory of partial differential equations in the direction initiated by Euler and continued by Laplace, Legendre, Imschenetsky, Darboux, Goursat. In her PhD thesis she extended to higher-order equations Laplace’s method of integration of second-order linear hyperbolic equations with two independent variables."
Later life
Petrén married Ernest Overton, a professor at Lund, but as a woman could not obtain a position there herself. Instead she became a part-time schoolteacher and actuary, and raised a family of four children.

https://en.wikipedia.org/wiki/QM-AM-GM-HM%20Inequalities | In mathematics, the QM-AM-GM-HM inequalities, also known as the mean inequality chain, state the relationship between the harmonic mean, geometric mean, arithmetic mean, and quadratic mean (also known as root mean square). Suppose that are positive real numbers. Then
These inequalities often appear in mathematical competitions and have applications in many fields of science.
Proof
There are three inequalities between means to prove. There are various methods to prove the inequalities, including mathematical induction, the Cauchy–Schwarz inequality, Lagrange multipliers, and Jensen's inequality. For several proofs that GM ≤ AM, see Inequality of arithmetic and geometric means.
AM-QM inequality
From the Cauchy–Schwarz inequality on real numbers, setting one vector to :
hence . For positive the square root of this gives the inequality.
HM-GM inequality
The reciprocal of the harmonic mean is the arithmetic mean of the reciprocals , and it exceeds by the AM-GM inequality. implies the inequality:
The n = 2 case
When n = 2, the inequalities become

which can be visualized in a semi-circle whose diameter is [AB] and center D.
Suppose AC = x1 and BC = x2. Construct perpendiculars to [AB] at D and C respectively. Join [CE] and [DF] and further construct a perpendicular [CG] to [DF] at G. Then the length of GF can be calculated to be the harmonic mean, CF to be the geometric mean, DE to be the arithmetic mean, and CE to be the quadratic mean. The inequalities then follow easily by the Pythagorean theorem.
Tests
To infer the correct order, the four expressions can be evaluated with two small numbers.
For and in particular, this results in .

https://en.wikipedia.org/wiki/African%20diaspora%20in%20Finland | The African diaspora in Finland () refers to the residents of Finland of full or partial African ancestry, mostly from Sub-Saharan Africa. According to Statistics Finland, the total number of people in Finland with a close African background (Africans in Finland; ) was 57,496 in 2020.
The distinct adjacent term Afro-Finns (), also referred to as Black Finns (), can be used for Finns whose lineages are fully or partly in the populations of Sub-Saharan Africa ("Black Africa"). Afro-Finns have lived in Finland since the 19th century, and in 2009, according to Yle, there were an estimated 20,000 Afro-Finns in Finland.
History
Finns reacted to the first Africans in Finland with curiosity and amazement. During the 19th century, there were some Africans from the Americas who worked as servants for wealthy Russians in the Grand Duchy of Finland. The first known African who received Finnish citizenship was Rosa Lemberg who came to Finland from Ovamboland in 1888 and received Finnish citizenship in 1899.
Between the 1900s and the 1970s, the few Africans in Finland were mostly either students (for example from Nigeria and Ethiopia), political exiles from South Africa or people married to Finns. In World War II (1939–1945), there were some Afro-Finnish soldiers, and among them were Private 1st Class , who served as a ski patrol leader in the Karelian Isthmus and was killed in the Winter War, and Corporal Holger Sonntag, who was of African-American and German descent and served as a driver in both the Winter War and Continuation War.
In 1990, during the Somali Civil War, the first Somali refugees arrived in Finland. After that, due to their high total fertility rate and the high number of Somali family reunifications, quota refugees and asylum seekers, they rapidly became the largest African group in Finland. During the 2003 FIFA U-17 World Championship held in Finland, most of the Sierra Leone national under-17 football team's players defected to Finland due to their country's poor conditions after a civil war that had ended a year earlier.
Nowadays most people of African ancestry come to Finland from Africa, but many have also come from the United States, Latin America and other European countries. Especially Americans and British people of African ancestry have moved to Finland, mostly through marriage.
Demographics
As of 31 December 2020, according to Statistics Finland, the total number of people in Finland with a close African background is 57,496, which is 1.0% of the population of Finland. 47,041 (81.8%) of them are from Sub-Saharan Africa. 32,511 (56.5%) of them are men, while 24,985 (43.5%) are women.
Countries of origin
Countries with a significant African diaspora
The following countries outside Africa have a majority population of Afro-descendants (90% or more of the country's total population) and, as of 31 December 2020, a total of 127 expatriates or close descendants in Finland:

https://en.wikipedia.org/wiki/Naum%20Il%27ich%20Feldman | Naum Il'ich Feldman (26 November 1918 – 20 April 1994) was a Soviet mathematician who specialized in number theory.
Life
Feldman was born on 26 November 1918 in Melitopol, Zaporizhia Oblast of southeastern Ukraine.
He entered in 1936 the Faculty of Mathematics and Mechanics at the University of Leningrad where he specialized in number theory under the supervision of Rodion O. Kuzmin. After his graduation in 1941, Feldman was called up by the army and served from October 1941 until the end of the World war II. For his service, he was awarded the Order of the Red Star, the Order of the Patriotic War (second class), and the medals "For the Capture of Königsberg", "For the Defence of Moscow", Medal "For the Victory over Germany in the Great Patriotic War 1941–1945".
After his demobilization, he started his PhD in 1946 at the Institute of Mathematics at the University of Moscow, under the supervision of Alexander O. Gelfond, and he presented his Ph.D. thesis in 1949. In 1950, he became head of the Department of Mathematics of the Ufimsky Oil Institute, where he was assigned until 1954. He lectured at the Moscow Geological Prospecting Institute from 1954 to 1961.
From September 1961 Feldman worked at Moscow State University, first in the department of mathematical analysis, and then in the department of number theory. In 1974 he became Doctor of Science. Feldman got full professorship in 1980.
Feldman died on 20 April 1994.
Work
Feldman obtained important results in number theory. His main research area were the theory of Diophantine approximations, the theory of transcendental numbers, and Diophantine equations.
In 1899, French mathematician Émile Borel strengthened the famous theorem of Charles Hermite that proved in 1873 the transcendence of the number without having been specifically constructed for this purpose. Later different estimates of the measure of transcendence were considered for other numbers too. Feldman's mentor Gelfond obtained his most famous result in 1948 in his eponymous theorem, also known as the 7th Hilbert's problem:
If α and β are algebraic numbers (with α≠0 and α≠1), and if β is not a real rational number, then any value of αβ is a transcendental number.
In 1949, Feldman further improved Gelfond's method to estimate of the measure of transcendence for logarithms of algebraic numbers and periods of elliptic curves. Of special importance is his result from 1960 on the measure of the transcendence of the number .

https://en.wikipedia.org/wiki/Tyler%20VanderWeele | Tyler J. VanderWeele is the John L. Loeb and Frances Lehman Loeb Professor of Epidemiology in the Departments of Epidemiology and Biostatistics at the Harvard T.H. Chan School of Public Health. He is also the co-director of Harvard University's Initiative on Health, Religion and Spirituality, the director of their Human Flourishing Program, and a faculty affiliate of the Harvard Institute for Quantitative Social Science. He holds degrees from the University of Oxford, University of Pennsylvania, and Harvard University in mathematics, philosophy, theology, finance, and biostatistics.
Research
VanderWeele’s research has focused on causal inference in epidemiology, the study of happiness and human flourishing, as well as the relationship between religion and health. He is author of the book Measuring Well-Being
, along with an influential approach to conceptualizing and assessing flourishing.
He has defined flourishing as a “state in which all aspects of a person’s life are good.” He is project co-director of the Global Flourishing Study, a $43.4 million study in collaboration with researchers at Harvard University, Baylor University, Gallup, and the Center for Open Science, with over 200,000 participants in 22 countries from six continents with five waves of annual data collection on the factors that influence human flourishing. VanderWeele also conducts research focused on theory and methods for distinguishing between association and causation in the biomedical and social sciences. His contributions to causal inference include introducing the E-value as a quantitative measure for sensitivity analysis and advances in mediation analysis along with the book, Explanation in Causal Inference, on the topic.
His work on causal inference is grounded in the potential outcomes framework, which is a popular approach, but not embraced by everyone.
He is also an author of the book Modern Epidemiology, described as “the standard textbook in all academic institutions for a long time to come… as a reference and encyclopedia.”
VanderWeele has published studies on religious service attendance and its relation to lowering mortality, depression, suicide, divorce, and improving many other outcomes.
Awards and honors
VanderWeele is recipient of the Mortimer Spiegelman Award from the American Public Health Association (2014); the John Snow Award from the American Public Health Association (2017); and the Presidents’ Award from the Committee of Presidents of Statistical Societies (COPSS) (2017) for “fundamental contributions to causal inference and the understanding of causal mechanisms; for profound advancement of epidemiologic theory and methods and the application of statistics throughout medical and social sciences; and for excellent service to the profession including exceptional contributions to teaching, mentoring, and bridging many academic disciplines with statistics.” He was elected a Fellow of the American Statistical Association in 2014, the Am |

https://en.wikipedia.org/wiki/Besse%20Day | Besse Beulah Day (later known as Besse Day Mauss, 1889–1986) was an American statistician known for her contributions to the statistics of forestry and naval engineering, and in particular for pioneering the use of design of experiments in engineering.
Education and career
Day was born in 1889 in Chapel Hill, Missouri.
She earned a bachelor's degree in mathematics at Central Missouri State Teachers College, and a master's degree in mathematics and statistics in 1927 from the University of Michigan School of Forestry and Conservation.
She worked for the Victor Talking Machine Company from 1927 to 1929 before joining the United States Forest Service in 1930. In 1943 she moved to Johns Hopkins University to assist the war effort by helping develop a radio-based proximity fuze. After the war she became head of statistics at the United States Naval Engineering Experiment Station in Annapolis, Maryland, and later a consulting statistician for the Bureau of Ships. As part of her work for the Navy, she transferred her knowledge of the design of experiments from forestry to naval engineering, for example using this method to determine which types of steel were susceptible to cracks in welding.
In 1960 she and her husband, contractor Charles E. Mauss, bought a house on South Carolina Avenue in Washington, DC, where they lived until retiring in 1969 to New Oxford, Pennsylvania.
She died on September 14, 1986, in New Oxford.
Recognition
Day became a Fellow of the American Statistical Association in 1951 for being "diligent in the applications of statistical theory to the two widely separated fields of forestry and engineering". She also became a Fellow of the American Association for the Advancement of Science in 1951.
In 1958, she was elected to the Washington Academy of Sciences "in recognition of her pioneer work in the statistical design of experiments in many fields particularly those of forestry and engineering and for her unique achievements in the exposition of statistical methods". She was also a fellow of the American Society for Quality Control.
Her 1955 paper "The technique of regression analysis" was the 1956 winner of the Brumbaugh Award of the American Society for Quality, as the year's best contribution to the industrial application of quality control.

https://en.wikipedia.org/wiki/Georgii%20Suvorov | Georgii Dmitrievic Suvorov (19 May 1919 – 12 October 1984) was a Soviet mathematician who made major contributions to the function theory and topology.
Biography
Suvorov was born on 19 May 1919 in Saratov. He graduated in mathematics from the Tomsk University in 1941. From 1941 to 1946, he served in the Soviet Army. For his military service, he was awarded the medals "For the Defense of Moscow" (1944), "For the Victory over Germany in the Great Patriotic War of 1941–1945" (1946) and "For the Victory over Japan" (1946). He was demobilized with the rank of lieutenant. After demobilization, he taught for several months at the Stalin Pedagogical Institute in Donesk.
He then returned to the Tomsk University to research under the supervision of Pavel Parfenevich Kufarev (1909–1968). Between 1951 and 1966, Suvorov worked as an assistant, then lecturer and finally became professor in the Faculty of Mechanics and Mathematics. Finally in 1961 he defended his D.Sc. dissertation entitled "Main properties of certain classes of topological mappings of plane domains with variable boundaries." In 1965, he was elected to Ukrainian SSR branch of the Academy of Sciences of the Soviet Union.
In 1966, he became the Head of the Department of the Theory of Functions at the Donetsk Computing Centre, which later became the Institute of Applied Mathematics and Mechanics of the Ukrainian SSR Academy of Sciences.
Suvorov died on 11 October 1984 in Donestk, Ukraine.
Works
Suvorov was the founder of a new branch of function theory concerned with the study of classes of plane and spatial mappings with bounded Dirichlet integral and of a new trend in mathematics at the border of the theory of functions and general topology that deals with the topological aspects of the boundary correspondence in a conformal mapping.
Suvorov made major contributions on the theory of topological and metric mappings on 2-dimensional space. Later at Donetsk he extended Lavrent'ev's work on stability and differentiable function theorems, to more general classes of transformations. Suvorov introduced new methods to help in the understanding of metric properties of mappings with bounded Dirichlet integral.
Suvorov and Oleg Ivanov collaborated on a number of papers culminating in a joint monograph “Complete lattices of conformally invariant compactifications of a domain”.
Suvorov published his authoritative monograph "Families of plane topological mappings" in 1965. He published in 1981 a monograph "The metric theory of prime ends and boundary properties of plane mappings with bounded Dirichlet integrals. (Metricheskaya teoriya prostykh kontsov i granichnye svojstva ploskikh otobrazhenij s ogranichennymi integralami Dirikhle). (Russian)". Two of his monographs were posthumously published in 1984 "The generalized "length and area principle" in mapping theory. (Obobshchennyj “printsip dliny i ploshchadi” v teorii otobrazheniya). (Rus |
https://en.wikipedia.org/wiki/Constant%20chord%20theorem | The constant chord theorem is a statement in elementary geometry about a property of certain chords in two intersecting circles.
The circles and intersect in the points and . is an arbitrary point on being different from and . The lines and intersect the circle in and . The constant chord theorem then states that the length of the chord in does not depend on the location of on , in other words the length is constant.
The theorem stays valid when coincides with or , provided one replaces the then undefined line or by the tangent on at .
A similar theorem exists in three dimensions for the intersection of two spheres. The spheres and intersect in the circle . is arbitrary point on the surface of the first sphere , that is not on the intersection circle . The extended cone created by and intersects the second sphere in a circle. The length of the diameter of this circle is constant, that is it does not depend on the location of on .
Nathan Altshiller Court described the constant chord theorem 1925 in the article sur deux cercles secants for the Belgian math journal Mathesis. Eight years later he published On Two Intersecting Spheres in the American Mathematical Monthly, which contained the 3-dimensional version. Later it was included in several textbooks, such as Ross Honsberger's Mathematical Morsels and Roger B. Nelsen's Proof Without Words II, where it was given as a problem, or the German geometry textbook Mit harmonischen Verhältnissen zu Kegelschnitten by Halbeisen, Hungerbühler and Läuchli, where it was given as a theorem.

She is the first chair in biomedical informatics and artificial intelligence at the Hospital for Sick Children.
Early life and education
As a young child born and raised in Voronezh, Russia, Goldenberg faced antisemitism in school. Eventually, in 1995, when she was 17 years old, Goldenberg's family left Russia and moved to Kentucky, U.S.A. There, Goldenberg completed a Bachelor of Engineering degree, in Engineering Mathematics and Computer Science, at the University of Louisville.
Goldenberg completed a Master's in Knowledge Discovery & Data Mining, followed by a PhD in machine learning at Carnegie Mellon University in Pittsburgh, where her thesis explored scalable graphical models for social networks. While in graduate school, Goldenberg was close with Joyce Feinberg - who was later one of 11 victims killed in the Pittsburgh's Tree of Life synagogue shooting in October 2018.
Research career
Goldenberg moved to Canada in 2008 as a post-doctoral fellow. She is currently appointed as an associate professor at University of Toronto's Department of Computer Science and the Department of Statistics and a scientist at the Hospital for Sick Children's Research Institute. Her laboratory explores how machine learning can be used to map the heterogeneity seen in various human diseases - specifically to develop methodologies to identify patterns in collected data and improve patient outcomes. She has more than 50 publications in peer-reviewed journals. Similarity Network Fusion, a networking method devised by her research group is the first data integration method developed to integrate patient data which improved survival outcome predictions in different cancers. She has an h-index of 17, and her research has been cited over 2,000 times.
In 2017, Goldenberg was appointed as a new Tier 2 CIHR-funded Canada Research Chair in Computational Medicine at the University of Toronto.
On 15 January 2019, Goldenberg was named the first chair in biomedical informatics and artificial intelligence at the Hospital for Sick Children, which is the first of its kind to exist in a Canadian children's hospital. This position is partially funded by a $1.75 million donation from Amar Varma (a Toronto entrepreneur whose newborn son underwent surgery at the Hospital for Sick Children).

Contributions
Some of Lamale's earliest work with the Bureau of Labor Statistics (published under the name Helen Humes) studied the effect of World War II on housing.
Her later work documented a general increase in the standard of living for working-class families through the economic boom of the 1950s.
Her book Methodology of the Survey of Consumer Expenditures in 1950, Study of Consumer Expenditures, Incomes and Savings in the United States (published by the Wharton School of the University of Pennsylvania in 1959) became "the most complete account put into print of the design and procedures" of the 1950 Survey of Consumer Expenditures, carried out jointly by the Bureau of Labor Statistics and the Wharton School.
Recognition
In 1966, Lamale was elected as a Fellow of the American Statistical Association "for significant contributions to the design and execution of consumer expenditure surveys and standard budget studies and to the analysis of levels and standards of living."

https://en.wikipedia.org/wiki/Conical%20spiral | In mathematics, a conical spiral, also known as a conical helix, is a space curve on a right circular cone, whose floor projection is a plane spiral. If the floor projection is a logarithmic spiral, it is called conchospiral (from conch).
Parametric representation
In the --plane a spiral with parametric representation
a third coordinate can be added such that the space curve lies on the cone with equation :
Such curves are called conical spirals. They were known to Pappos.
Parameter is the slope of the cone's lines with respect to the --plane.
A conical spiral can instead be seen as the orthogonal projection of the floor plan spiral onto the cone.
Examples
1) Starting with an archimedean spiral gives the conical spiral (see diagram)
In this case the conical spiral can be seen as the intersection curve of the cone with a helicoid.
2) The second diagram shows a conical spiral with a Fermat's spiral as floor plan.
3) The third example has a logarithmic spiral as floor plan. Its special feature is its constant slope (see below).
Introducing the abbreviation gives the description: .
4) Example 4 is based on a hyperbolic spiral . Such a spiral has an asymptote (black line), which is the floor plan of a hyperbola (purple). The conical spiral approaches the hyperbola for .
Properties
The following investigation deals with conical spirals of the form and , respectively.
Slope
The slope at a point of a conical spiral is the slope of this point's tangent with respect to the --plane. The corresponding angle is its slope angle (see diagram):
A spiral with gives:
For an archimedean spiral is and hence its slope is
For a logarithmic spiral with the slope is ( ).
Because of this property a conchospiral is called an equiangular conical spiral.
Arclength
The length of an arc of a conical spiral can be determined by
For an archimedean spiral the integral can be solved with help of a table of integrals, analogously to the planar case:
For a logarithmic spiral the integral can be solved easily:
In other cases elliptical integrals occur.
Development
For the development of a conical spiral the distance of a curve point to the cone's apex and the relation between the angle and the corresponding angle of the development have to be determined:
Hence the polar representation of the developed conical spiral is:
In case of the polar representation of the developed curve is
which describes a spiral of the same type.
If the floor plan of a conical spiral is an archimedean spiral than its development is an archimedean spiral.
In case of a hyperbolic spiral () the development is congruent to the floor plan spiral.
In case of a logarithmic spiral the development is a logarithmic spiral:
Tangent trace
The collection of intersection points of the tangents of a conical spiral with the --plane (plane through the cone's apex) is called its tangent trace.

https://en.wikipedia.org/wiki/Jack%20O%27Neill%20%28statistician%29 | John Patrick O'Neill (1910 – 11 October 1998) was an Australian public servant, who served as Australia's Commonwealth Statistician (head of the Bureau of Statistics) from 1970 to 1975, and Australian Statistician from 1975 to 1976.
O'Neill was born in Wynyard, Tasmania where he attended primary school, later boarding at St Virgil's College in Hobart. In 1927, he began working at the Hobart office of the Commonwealth Bureau of Census and Statistics, and began studying for a Bachelor of Commerce degree at the University of Tasmania which he discontinued due to illness. In 1937, he transferred to the Bureau's Canberra office working under Roland Wilson, with secondments to the Bureau of Meteorology and Department of Commerce and Agriculture during World War II.
When the Commonwealth Statistician—his friend and colleague, fellow Tasmanian Keith Archer—took sick leave in 1970, O'Neill acted as Commonwealth Statistician until he was officially appointed in 1972, then continued as the Australian Statistician when the role and the Bureau were renamed in 1975, until he retired due to invalidity in August that year.

https://en.wikipedia.org/wiki/Amicable%20triple | In mathematics, an amicable triple is a set of three different numbers so related that the restricted sum of the divisors of each is equal to the sum of other two numbers.
In another equivalent characterization, an amicable triple is a set of three different numbers so related that the sum of the divisors of each is equal to the sum of the three numbers.
So a triple (a, b, c) of natural numbers is called amicable if s(a) = b + c, s(b) = a + c and s(c) = a + b, or equivalently if σ(a) = σ(b) = σ(c) = a + b + c. Here σ(n) is the sum of all positive divisors, and s(n) = σ(n) − n is the aliquot sum.

https://en.wikipedia.org/wiki/Philip%20McShane | Philip McShane (18 February 1932 – 1 July 2020) was an Irish mathematician and philosopher-theologian. Originally trained in mathematics, mathematical physics, and chemistry in the 1950s, he went on to study philosophy from 1956 to 1959. In 1960, after teaching mathematical physics, engineering, and commerce to undergraduates, and special relativity and differential equations to graduate students, McShane began studying theology. He did his fourth year of theology in 1963 and in 1968 began reading economics.
In a period that spanned over sixty years, McShane published numerous articles and twenty-five books. His publications range from technical works on the foundations of mathematics, probability theory, evolutionary process, and omnidisciplinary methodology, to introductory texts focusing on critical thinking, linguistics, and economics. He also wrote essays on the philosophy of education. Beginning in 1970, he participated in and helped organize a number of international workshops and conferences addressing topics such as "ongoing collaboration," reforms in education, and communicating the basic insights of two-flow economics.
Two Festschrift volumes were published to honor McShane, one in 2003 and the second in 2022. In the first, eighteen individuals contributed essays, and, at the request of the editor, McShane submitted an essay as well. He also replied to the eighteen contributors in the essay "Our Journaling Lonelinesses: A Response.” In the second Festschrift, twenty-four individuals wrote essays remembering and honoring McShane, who was nominated for the Templeton Prize in 2011 and 2015.
Life and Education
McShane was born in Baileboro, County Cavan. When the McShane family moved to Dublin, Philip went to O'Connell School. He continued his education while training as a Jesuit at University College Dublin (BSc and MSc in relativity theory and quantum mechanics), St Stanislaus College, Tullabeg (Lic. Phil), Heythrop College (STL) and Campion Hall, Oxford (D.Phil). He lectured in Mathematics at University College Dublin (1959-1960) and in Philosophy at the Milltown Institute of Theology and Philosophy (1968-1973).
McShane entered the Jesuits in September 1950 and spent two years in spiritual formation. In 1952, in spite of having "acquired a 'broken head,' which meant he was unable to study, or even to do any serious reading, he was also allowed to risk a very challenging programme of mathematics, mathematical physics, physics and chemistry." Eleven years later, after completing a B.Sc., an M.Sc. in relativity theory and quantum mechanics, and a Licentiate of Philosophy, he was ordained a Jesuit priest.
In 1956, McShane "shifted from graduate studies of mathematics and physics that included such works as the classic Space-Time Structure by Erwin Schrödinger," and embarked on what would be a lifelong venture of reading and appropriating the works of Bernard Lonergan, initially through a careful study of Lonergan's Verbum articles, |

https://en.wikipedia.org/wiki/Samuel%20James%20Patterson | Samuel James Patterson (September 7, 1948 in Belfast) is a Northern Irish mathematician specializing in analytic number theory. He has been a professor at the University of Göttingen since 1981.
Biography
Patterson was born in Belfast and grew up in the east of the city, attending Grosvenor High School. He went to Clare College, Cambridge, in 1967, and received his BA in mathematics in 1970, and his Ph.D. (completed in 1974, awarded in 1975) on "The limit set of a Fuchsian group" under Alan Beardon. He spent 1974–1975 at Göttingen, 1975–1979 he was back at Cambridge, and 1979–1981 he was at Harvard as Benjamin Pierce Lecturer. From 1981 to his retirement in 2011 he was professor of mathematics at Göttingen.
His 18 PhD students include Jörg Brüdern and Bernd Otto Stratmann.
He is the brother of the Northern Irish taxonomist David Joseph Patterson.
Mathematics
Subjects that Patterson deals with include discontinuous groups (Fuchsian groups), different zeta functions (for example those of Ruelle and Selberg, in particular those associated with certain groups of infinite covolume), metaplectic groups, generalized theta functions, and exponential sums in analytical number theory.
In 1978, together with Roger Heath-Brown, he disproved the Kummer conjecture on cubic Gauss sums.
He proposed a new conjecture which was based on insights from his determination of the coefficients of the cuspidal Fourier expansions of the metaplectic cubic theta function. This revised conjecture remained open until 2021, when it was finally proved by Alexander Dunn and Maksym Radziwiłł at Caltech.
In 1976 Patterson introduced what later became known as the Patterson-Sullivan measure. The concept was further developed and extended by Dennis Sullivan starting in 1979. It has proved to be a useful tool in studying Fuchsian and Kleinian groups (and certain generalizations) and their limit sets.
History of mathematics
Patterson is also interested in the history of mathematics. For example, together with Ralf Meyer, he contributed an updated introduction to a new edition of a classic textbook by Hermann Weyl, and an introduction to the classic textbook of Whittaker and Watson. He has collaborated with Norbert Schappacher on elucidating the biography of Kurt Heegner.
Honors and awards
In 1984 Patterson received the Whitehead Prize of the London Mathematical Society. He is on the Executive Committee of the Leibniz Archives based in Hannover and has been a member of the Göttingen Academy of Sciences since 1998. From 1982 to 1994 he was an editor of Crelle's Journal.
To mark his 60th birthday friends and colleagues in Göttingen organized a three day conference to celebrate his life in July, 2009. Speakers at this gathering included Daniel Bump, Dorian Goldfeld,
David Kazhdan, and Andrew Ranicki. A commemorative volume, Contributions in Analytic and Algebraic Number Theory (Springer 2012), edited by Valentin Blomer & Preda Mihăilescu, collecting articles related to or de |
https://en.wikipedia.org/wiki/Johannes%20Tropfke | Johannes Tropfke (14 October 1866 – 10 November 1939) was a German mathematician and teacher, who is best remembered for his influential work on the history of mathematics Geschichte der Elementarmathematik, which consists of seven volumes.
Life
Tropfke was born in Berlin at Marienstraße 14 as the older of two sons of the cabinet maker Franz Tropfke. The house in which Tropfke was born was built by his grandfather Franz Joseph Tropfke around 1830 and is one of the few houses in the area that was not destroyed during World War II. Tropfke grew up in Berlin and after his graduation from the Friedrichs-Gymnasium (high school) in 1884 he attended the university in Berlin to study sciences and mathematics. In 1889 he was awarded a degree to teach math and sciences at gymnasiums (high schools). Later he earned a PhD in mathematics from the University of Halle for a thesis on elliptic integrals (Zur Darstellung des elliptischen Integrales erster Gattung), his advisor was Lazarus Fuchs.
Tropfke first worked as teacher at the Friedrichs-Realgymnasium and at the Realgymnasium of Dorotheenstadt and in 1913 he became the principal of the newly founded Kirschner-Oberrealschule in Moabit. Tropfke stayed on in this position until his retirement in 1932. In 1907 he was awarded the title of a professor. He was one of the first members of the International Academy of the History of Science and in 1939 he was awarded the Leibniz medal by the Prussian Academy of Sciences.
Aside from his work in education and mathematics Tropfke also had a career in local politics. He was a member of the German People's Party and served as council member for the city of Berlin from 1907 to 1920.
Tropfke married Frida Thyssen. The couple had a son Erich, who perished in World War I, and a daughter Elisabeth. Tropfke died on 10 November 1939 in the very same house in which he was born.
Work
Tropfke's most important contributions were in the history of mathematics. His seminal work Geschichte der Elementarmathematik originally consisted of two volumes, when it was first published in 1902 and 1903. Later it got expanded into seven volumes for its second edition (1921-1924). For this second edition Tropfke was supported by the mathematicians and historians Gustaf Eneström, Julius Ruska and Heinrich Wieleitner. To incorporate the latest research Tropfke published revised third editions of the first three volumes in the 1930s. After his death the mathematician Kurt Vogel completed the third edition of the fourth volume in 1940. The structure and focus of Tropfke's work differed somewhat from most work in the history of mathematics at the time. Instead of structuring the material chronologically with a focus on the biography of mathematicians, Tropfke selected to organize it by mathematical fields and then focused on the development of concepts and terminology in those fields rather than on biographical aspects. In particular with its second edition Tropfke's Geschichte der Elementa |

Michler earned her Ph.D. in Mathematics in 1993 from the University of California, Berkeley. Her dissertation is titled "Hodge components of cyclic homology of affine hypersurfaces." Her advisors were Mariusz Wodzicki and Arthur Ogus. She spent the academic year 1993-1994 as a postdoc at Queen's University working with Leslie Roberts. In 1994, she joined the tenure-track faculty at the University of North Texas where she earned tenure in 2000. She was the author of eleven (11) research articles in commutative algebra and algebraic geometry. She organized several special sessions at meetings of the American Mathematical Society. The session in San Antonio resulted in a conference proceedings which Michler co-edited. In 2000 she was awarded a National Science Foundation POWRE grant to visit Northeastern University.
Memorial conferences and prize
Michler was killed in an accident in Boston on November 1, 2000, when she was struck by a construction vehicle while riding her bicycle. Several conferences were organized in her honor. Two conferences resulted in a volume of papers dedicated to her memory which includes a dedicatory article and an article describing her research. In 2007 the Association for Women in Mathematics inaugurated the Ruth I. Michler Memorial Prize which is "awarded annually to a woman recently promoted to Associate Professor or an equivalent position in the mathematical sciences".

https://en.wikipedia.org/wiki/Sue%20Geller | Sue Geller is an American mathematician and a professor emerita of mathematics at the department of mathematics at Texas A&M University. She is noted for her research background in algebraic K-theory, as well as her interdisciplinary work in bioinformatics and biostatistics, among other disciplines.
Research
Sue Geller has an extensive and largely interdisciplinary research background with a variety of focus areas, including bioinformatics, biostatistics, computational biology, algebraic K-theory, cyclic homology, and mathematics education. Throughout her career as a mathematician, Geller has published over thirty research publications, earning her notability as an accomplished interdisciplinary researcher.
Geller's research in the fields of algebraic K-theory, cyclic homology, and Hochschild homology focuses on determining the relationships between K-theory and homology theories and exploiting these relationships to provide algorithms for computing K-theory and cyclic homology. Her algebraic research has been published in a variety of academic journals, as well as presented at the 1983 Summer Research Conference held by the American Mathematical Society (AMS).
Her foray into the fields of bioinformatics and biostatistics has led her to research methods of addressing challenges faced when analyzing data produced by microarray technology, which provides ways of studying active genes in different cell tissue types. Primarily, Geller investigates methods of analyzing relatively small samples using new statistical methods.
Though she has not published any formal research in mathematics education, Geller developed a keen interest in the subject in 2000 and has since served as a doctoral advisor for two students with a mathematics education specialty. She also began conducting research on the information available from college applications and how it correlates to success in university honors programs for freshman students. Within this, she is researching the correlation of the Math Placement Exam incoming college students take and their success in their recommended math class with a goal to improve advising.
Education
Sue Geller obtained her B.S. in mathematics from the Case Institute of Technology in 1970. Upon graduation she continued her education at Cornell University, where she earned her M.S. in mathematics in 1972, followed by her Ph.D. in mathematics from the same institution in 1975.
Studying under advisor and Cornell faculty member Stephen Chase, the primary focus of Geller's graduate research was in algebraic K-theory, as reflected in the title of her doctoral dissertation, On the GE(sub n) of a Ring and Some New Algebraic K-Groups. She also worked as a teaching assistant and lecturer for Cornell during her graduate studies. Geller was one of twenty-one women awarded a doctorate in mathematics at Cornell University during the years 1868 to 1939, in which one hundred doctorates total were awarded by the Cornell Department of Mathemat |

https://en.wikipedia.org/wiki/Fr%C3%A9d%C3%A9rique%20Lenger | Frédérique Papy-Lenger (August 12, 1921 – January 9, 2005) was a Belgian mathematician and mathematics educator active in the New Math movement of the 1960s and 1970s.
Early life and education
Frédérique Lenger was born on August 12, 1921, in Arlon, Belgium, one of three daughters of a lawyer. After studying classics in the Lycée Royal d’Arlon, she studied for a licentiate in mathematics at the Université libre de Bruxelles from 1939 to 1943. The University officially closed in 1941 to prevent its takeover by the German occupation, and her studies continued underground.
In 1968, she completed a doctorate with a two-part thesis, one part on mathematics education and the other on geometric transformation groups.
Career
From 1947 to 1950, Lenger taught mathematics at the l’Ecole Decroly, while working as an assistant to mathematician Paul Libois, who suggested that she perform research involving projective geometry and triality. This became a precursor to the work of another student of Libois, Jacques Tits.
In 1950, Lenger joined the mathematics faculty of the Lycée Royal d’Arlon; in 1957, she was appointed prefect at Arlon and director of the State Normal School in Arlon.
She became a professor of mathematics at the Berkendael State Normal School in Brussels in 1960. In 1961, with several other mathematicians, she became one of the founders of the Centre Belge de Pédagogie de la Mathématique (Belgian Center for the Pedagogy of Mathematics). From 1974 to 1980 she worked in the US, at the Comprehensive School Mathematics Program in St. Louis, Missouri. She returned to Berkendael in 1980. She retired in 1981 but continued to work as a volunteer at the French school in Nivelles until 1992.
Contributions
Lenger began her work on developing a modern school mathematics curriculum in 1958, working with Willy Servais and in consultation with Georges Papy, whom she married in 1960. With Madeleine Lepropre, Lenger ran an experimental training program for kindergarten teachers based on the new curriculum in 1958–1959, and was encouraged by the enthusiasm the kindergarten students showed for the material. With Papy, in the mid-1960s, she developed a six-volume high-school mathematics program based on the principles of set theory and abstract algebra.
She was an invited plenary speaker at the first International Congress on Mathematical Education, speaking there on the "minicomputer" method for teaching binary number arithmetic to schoolchildren. She became the founding president of the International Research Group in Mathematical Pedagogy in 1971.
Her books include L'enfant et les graphes (Didier, 1968), Mathématique moderne (Didier, 1970), Modern mathematics (two vols., Collier, 1968 and 1969), Graph Games (Crowell, 1971), and Graphs and the Child (Harvard University Press, 1979). She also produced many educational booklets through the Belgian Center for the Pedagogy of Mathematics and the Comprehensive School Mathematics Program.

https://en.wikipedia.org/wiki/Crime%20in%20New%20South%20Wales | Criminal activity in New South Wales, Australia is combated by the New South Wales Police Force and the New South Wales court system, while statistics about crime are managed by the NSW Bureau of Crime Statistics and Research. Modern Australian states and cities, including New South Wales, have some of the lowest crime rates recorded globally with Australia ranked the 13th safest nation and Sydney ranked the 5th safest city globally. As of September 2018 the City of Penrith (475.7) and City of Blacktown (495.1). Rural areas have comparatively high crime rates per 100,000 with rural shires such as Walgett Shire (1350.3) and Moree Plains Shire (1236.2) having some of the highest violent crime rates in the state. The overall NSW crime rate has been in steady decline for many years.
New South Wales was founded as a British penal colony. The founding members of the colony included a significant number of criminals, known as convicts, there were 778 convicts (192 women and 586 men) on the First Fleet. The majority of convicts were transported for petty crimes. More serious crimes, such as rape and murder, became transportable offences in the 1830s, but since they were also punishable by death, comparatively few convicts were transported for such crimes. Common Crimes in the colony were drunkenness, assault, and disorderly prostitution. Bushranging and absconding were also common, while the murder rate was low. The rate of conviction for less serious offenses gradually declined. Execution was used as punishment, though the rate of execution was low.
NSW crime statistics
New South Wales crime statistics
The NSW Bureau of Crime Statistics and Research (BOCSAR) is the main source of NSW crime statistics. In 2017 BOCSAR reported an overall drop in recorded incidence with the murder rate (down 12.1%), robbery (down 8.0%), armed robbery (down 13.4%), burglary (Down 5.5%), motor vehicle theft (Down 3.2%) and malicious damage to property (Down 3.6%). There was an increase in the rate of Sexual assault (up 3.5%) and sexual offences (up 3.7%).
Massacres of Aboriginal Australians
Though often not recorded as crimes at the time, numerous crimes were perpetrated against Aboriginal Australians in New South Wales throughout the colonial period. Among the most heinous of these crimes were massacres. The following list tallies the better documented massacres of Aboriginal Australians in New South Wales. The information provided below is based on ongoing research 'Violence on the Australian Colonial Frontier, 1788–1960' undertaken by the Australian Research Council.
1816 Appin massacre – In March 1816, a punitive expedition of a group of settlers was surprised and ambushed at Silverdale by a group of Aboriginal people armed with muskets and spears; four settlers were killed. Governor Lachlan Macquarie ordered an armed reprisal "to inflict exemplary and severe punishment on the mountain tribes...to strike them with terror...clearing the country of them entirely." Ma |
https://en.wikipedia.org/wiki/Crime%20in%20Queensland | Crime in Queensland is an on-going political issue. Queensland Police is responsible for providing policing services to Queensland, Australia. Crime statistics for the state are provided on their website. Official records show that reported offences against property and people has declined over the past 20 years to 2020. The state has criminal codes for hooning, graffiti, sharing intimate images without consent and fare evasion. Wage theft became a crime in 2020. The minimum age of criminal responsibility in Queensland is 10 years old.
The long-term trend is for a decrease in crime in Queensland across all categories. Exceptions include rape, assault and shop theft which have increased. The rate of youth offending is falling. By age, the largest group of criminals was the 20-24 cohort.
The Crime and Corruption Commission (CCC) was created to combat and reduce the incidence of major crime and to reduce the incidence of misconduct in the Queensland public sector. Complaints about the police are rarely investigated by the CCC which passes police matters back to the service for internal review.
Community crime Facebook groups have grown in number and influence, becoming de facto lobby organisations. Police have raised concerns about the rise of vigilantism stemming from comments online.
History
In July 1987, the Fitzgerald Inquiry began formal hearings. The judicial inquiry investigated possible illegal activities and police misconduct. Fitzgerald's report was submitted on 3 July 1989. Queensland Police Commissioner Terry Lewis was charged with corruption and a number of politicians were charged with crimes. The Fitzgerald Inquiry lead to the establishment of Queensland's first anti-corruption body, the Criminal Justice Commission.
Crime Stoppers Queensland was established in 1989.
In August 2013, the Queensland Police Service launched an online crime map to provide crime data to the public. In October 2013, the Newman government led an unprecedented crackdown on outlaw motorcycle clubs.
In March 2023, Queensland police were given a substantial rise in powers. Legislation passed that allows Queensland police to use hand-held metal detectors to search people without reasonable suspicion in a crackdown on knife crime. In May 2023, an anti-crime rally was held in Rockhampton. After the rally a group of about 60 people marched on the homes of alleged offenders.
Illicit drugs
Small scale drug possession laws were changed in 2023 with the introduction of a three-strike system that offers a caution to a first-timer, and diversion and assessment programs for anyone busted two or three times. In the same year, mobile and fixed site pill testing was introduced in an attempt to curb the harmful effects of illicit drugs. Queensland’s peak medical bodies welcomed the move towards a health-based approach to drug use. The changes were made to save police time and to prevent further harm to small-time users.

https://en.wikipedia.org/wiki/Crime%20in%20Victoria | Criminal activity in Victoria, Australia is combated by the Victoria Police and the Victorian court system, while statistics about crime are managed by the Crime Statistics Agency. Modern Australian states and cities, including Victoria, have some of the lowest crime rates recorded globally with Australia ranked the 13th safest nation and Melbourne ranked the 5th safest city globally. As of September 2018 the CBD of Melbourne had the highest rate of overall criminal incidents in the state (15,949.9), followed by Latrobe (12,896.1) and Yarra (11,119.2). Rural areas have comparatively high crime rates, with towns such as Mildura (9,222.0) and Greater Shepparton (9,111.8) having some of the highest crime rates in the state.
Victoria has had a comparatively low crime rate throughout its history, particularly in relation to the homicide rate which has been and remains notably lower than that of comparable nations. During the colonial period (1851–1901) drunkenness was the most widely reported crime, and in 1907 about 40% of all convictions nationwide were for drunkenness. Fraud was also common in the Victorian colony due to a shortage of currency and the common use of promissory notes. Victorian crime data and reporting prior to Australian Federation is generally seen as unreliable or inconsistent, with the exception of homicide rates.
Crime statistics
Statistics released by the Crime Statistics Agency in September 2018 showed a 7.8% drop in the overall crime rate. The statistics showed the criminal incident rate fell to 5,922 cases per 100,000 people in the previous year, continuing a trend of reduction in the overall number of criminal incidents from the previous year, with significant falls in theft, burglaries and drug dealing.
In the year ending September 2020, the statistics were skewed by the introduction of six new public safety offences relating to the COVID-19 pandemic in Australia.
