What is Git? Git is an open-source version control system that is used to efficiently manage projects ranging in size from small to huge. During software development, this software keeps track of changes in a set of files and can help coordinate work between programmers working on source code together. Linus Torvalds founded it in … Read more

Stars Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Many stars occur in pairs, multiple systems, or star clusters. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night, but due to their immense distance from Earth they … Read more

What Is Diabetes mellitus? Diabetes mellitus commonly referred to as Diabetes is a group of metabolic disorders characterized by a high blood sugar level over a prolonged period of time. This type of diabetes is generally due to either the pancreas not producing enough insulin or the cells of the body not responding properly to … Read more

Inner Planets/Terrestrial Planets The inner planets also referred to as terrestrial planets are the four planets closest to the Sun. they include: Mercury, Venus, Earth and Mars. These planets are smaller and denser than their counterparts (outer planets) and have few to no moons or rings circling them. Mercury and Venus do not have moons, … Read more

The Crystal Field Theory (CFT) is a model for the bonding interaction between transition metals and ligands. It describes the effect of the attraction between the positive charge of the metal cation and negative charge on the non-bonding electrons of the ligand. When the ligands approach the central metal ion, the degeneracy of electronic orbital … Read more

Reviewed By Dr. Ezekiel Oburu (M.D, PhD, FACR) What Is Osteoarthritis? Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It occurs when the protective cartilage that cushions the ends of your bones wears down over time. The wearing of cartilage causes the bones to rub against each other. This can … Read more

The heart is a pump made up of muscle tissue. Like all muscle, the heart needs a source of energy and oxygen to function. The heart’s pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart. The Electrical pulses in the heart are controlled by … Read more

What Is Octane Number? An octane rating also referred to as octane number, is a standard measure of an engine or aviation gasoline capability against compression. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass … Read more

What Is Centripetal Force? According to Newton’s first law of motion, a moving body travels along a straight path with constant speed (i.e., has constant velocity) unless it is acted on by an outside force. For circular motion to occur there must be a constant force acting on a body, pushing it toward the center of the … Read more

What Is DIAC (Diode For Alternating Current)? DIAC is a bidirectional semiconductor switch that can be turned ON in both forward and reverse direction. The device is a member of the Thyristor family and it is mostly used in triggering TRIAC and other Thyristor based circuits. The DIAC starts conducting electric current if the applied … Read more
