Star transit A star transit is the passage of a star across the field of view of a telescope eyepiece. The precise observation of star transits is the basis of many methods in astronomy and in geodesy. The measurements can be done in different ways: | https://en.wikipedia.org/wiki?curid=1428417 |
Lechatelierite is silica glass, amorphous SiO, non-crystalline mineraloid. is a mineraloid as it does not have a crystal structure. Although not a true mineral, it is often classified in the quartz mineral group. One common way in which lechatelierite forms naturally is by very high temperature melting of quartz sand d... | https://en.wikipedia.org/wiki?curid=1430367 |
Transition point In the field of fluid dynamics the point at which the boundary layer changes from laminar to turbulent is called the transition point. Where the boundary layer becomes turbulent, drag due to skin friction is relatively high. As speed increases, the upper surface transition point tends to move forward. ... | https://en.wikipedia.org/wiki?curid=1436372 |
Argo (crater) Argo is a crater in the Meridiani Planum on Mars, which was visited by the "Opportunity" rover on approximately its 365th Martian sol. The crater is about south of the heat shield and Heat Shield Rock. | https://en.wikipedia.org/wiki?curid=1441730 |
Hirayama family A of asteroids is a group of minor planets that share similar orbital elements, such as semimajor axis, eccentricity, and orbital inclination. The members of the families are thought to be fragments of past asteroid collisions. Strictly speaking, families and their membership are identified by analysing... | https://en.wikipedia.org/wiki?curid=1443842 |
Neelanjali Ruby The Neelanjali Ruby, at 1,370 carats (274 g), is the world's largest double-star ruby. A ruby is known as a star ruby if it contains an asterism (distinctive star-shaped light refraction) in the gem. The is the world's largest star ruby with a 12-point asterism, which is commonly denoted as a double-sta... | https://en.wikipedia.org/wiki?curid=1444198 |
Rheotaxis (Positive) is a form of taxis seen in many aquatic organisms, e.g., fish, whereby they will (generally) turn to face into an oncoming current. In a flowing stream, this behavior leads them to hold their position rather than being swept downstream by the current. has been noted in zebrafish and other species, ... | https://en.wikipedia.org/wiki?curid=1449913 |
Rheotaxis Recently, it was observed that certain self-propelled particles (gold-platinum nanorods) will rheotax and reorient themselves against the flow in small microfluidic channels. | https://en.wikipedia.org/wiki?curid=1449913 |
Charles Joseph Gahan (20 January 1862 – 21 January 1939) was an Irish entomologist who specialized in beetles particularly the Cerambycidae. He served as keeper at the department of entomology in the British Museum (Natural History) for thirteen years after Charles Owen Waterhouse. He was born on 20 January 1862 at Ros... | https://en.wikipedia.org/wiki?curid=1452409 |
John A. McClelland John Alexander McClelland FRS (1 December 1870 – 13 April 1920) was an Irish physicist known for pioneering work on the scattering of β rays, the conductivity of gases, and the mobility of ions.

Metallizing is the general name for the technique of coating metal on the surface of objects. Metallic coatings may be decorative, protective or functional. Techniques for metallization started as early as mirror making. In 1835, Justus von Liebig discovered the process of coating a glass surface with metallic silver, ... | https://en.wikipedia.org/wiki?curid=1454099 |
Metallizing Thermal spray processes are often referred to as metallizing. Metals applied in such a manner provide corrosion protection to steel for decades longer than paint alone. Zinc and aluminum are the most commonly used materials for metallizing steel structures. Cold sprayable metal technology is a metallizing p... | https://en.wikipedia.org/wiki?curid=1454099 |
Crookesite is a selenide mineral composed of copper and selenium with variable thallium and silver. Its chemical formula is reported either as Cu(Tl,Ag)Se or (Cu,Tl,Ag)Se. It is formed by precipitation from hydrothermal fluids, and contains by mass: 16.3% Tl, 47.3% Cu, 2.9% Ag, and 33.6% Se. is an opaque, bluish grey t... | https://en.wikipedia.org/wiki?curid=1467854 |
