Mercury is the closest planet to our Sun, the smallest of the eight planets, and one of the most extreme worlds in our Solar Systems. Named for the Roman messenger of the Gods, the planet is one of a handful that can be viewed without the aid of telescopes. As such, it has played an active role in the mythological and ...
The invention of printing also fostered the scientific revival by making it easy to spread knowledge abroad in every land. The pioneers of Renaissance science were Italians, but students in France, England, Germany, and other countries soon took up the work of enlightenment. The names of some Renaissance scientists sta...
In the previous part of Lesson 2, the use of kinematic equations to solve projectile problems was introduced and demonstrated. These equations were used to solve problems involving the launching of projectiles in a horizontal direction from an elevated position. In this section of Lesson 2, the use of kinematic equatio...
A comet’s nucleus is in the center of its coma. A comet’s nucleus is like a snowball made of ice. As the comet nears the Sun, the ice starts to melt off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma. A comet’s nucleus, or heart, is the solid chunk of something i...

And the series of Ku Klux Klan Acts, which had incremental...
Garbage collection (GC) in Solid-State Drives (SSDs) is a crucial process for managing data storage and maintaining drive efficiency.

A histogram is a graph that shows the frequency, or the number of t...
Almost all known neutron stars are also known as pulsars, because they emit pulsed beams of radio waves or X rays that sweep past Earth like lighthouse beams. But on most occasions, these beams miss Earth, making the neutron star effectively invisible at radio or X-ray wavelengths. But according to some theoretical pre...

A rotation is a circular movement of an object around a center (or point) of rotation. The geometric plane along which the rotation occurs is called the rotation plane, and the imaginary line extending from the center and perpendicular to the rotation plane is called the rotation axis ( AK-seez). A three-dimensional ob...
This animation tracks several gamma rays through space and time, from their emission in the jet of a distant blazar to their arrival in Fermi's Large Area Telescope (LAT).

The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: w...

Soil erosion is the denudation of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals (including humans). In accordance with these agents, erosion is sometimes divided i...
2.1 Introduction: There are some physical quantities, which are completely described by a single number with a unit, for example; mass of a body. On the other hand, there are other quantities that need a direction specified along with the magnitude for a complete description. The quantities which are described only via...
The term ‘deep-sky objects’ is used by astronomers to refer to galaxies, nebulae or star clusters, which, as the name suggests, lie well beyond the limits of our solar system. Galaxies were originally classed as nebulae, until they were shown, by Edwin Hubble in the early 1920s (see Hubble’s Law), to be enormous collec...
In mathematics, a square root of a number a is a number y such that y2 = a, or, in other words, a number y whose square (the result of multiplying the number by itself, or y × y) is a. For example, 4 is a square root of 16 because 42 = 16. Every non-negative real number a has a unique non-negative square root, called t...
"Confirmation Bias" is a pervasive danger to hypothesis creation and testing. The information that we sense and perceive is filtered through our beliefs and experiences (Elstein, 1999). For example, how people perceive and act on information is often based on heuristics (simple rules) instead of strong reasoning (Tvers...

Knowing the perimeter and the side pieces, you can find the other side and square. The perimeter, in turn, can be found in several specified parties or on the corner and sides, depending on the conditions of the problem. Also, in some cases, it is expressed through the area. The most simple is the perimeter of the rect...
COMPONENTS OF LOGARITHMS The fractional part of a logarithm is usuallywritten as a decimal. The whole number part of a logarithm and the decimal part have been given separate names because each plays a special part in relation to the number which the logarithm represents. The whole number part of a logarithm is called ...

It is measured in coulombs per meter (C/m), square meter (C/m²), or cubic meter (C/m³), respectively, and represented by the lowercase Greek letter Rho (ρ). Since there are positi...
How to find roots of a quadratic equation by factorising. A quadratic equation looks like this: ax² + bx + c = 0Â (where ‘a’ cannot be zero.) Solving the equation means finding ‘x’ values that make the equation true. These ‘x’ values are called the roots Â of the quadratic. Quadratic equations can have 0, 1 or two root...

A vector is a ray with both magnitude (size) and direction. A vector is different from a scalar in that a scalar has only magnitude. For example, speed is a scalar quantity, but velocity is a vector, because it gives both speed and direction. Vectors are used to show directed quantities, and can be thought of as the mo...
In astronomy, stars are classified based on their spectra. Different types of stars (listed below) have different spectral characteristics and, even though they only differ in brightness to the unaided eye, stars are divided into seven basic spectral classes and eight luminosity classes.
