What Is Ammonia? | Definition and Uses

Ammonia is a colorless gas that is produced from natural sources as well as industrial synthesis. About 175 million tons of ammonia is produced synthetically every year. More than 85% of produced ammonia is used as fertilizers and in household...

11 Different Types Of Forces

In physics, a force can be defined as a push or pull on any object that has mass. It changes the object’s motion. In other words, a force causes an object with mass to change its direction and velocity. Two great physicists Isaac Newton and...

15 Most Intriguing Facts About Atoms

Everything in the Universe — from Earth’s core to farthest galaxies — is made of atoms. It’s a fundamental unit of an element. So far, 118 elements have been identified (all are listed in the periodic table). The word...

11 Different Types Of Energy With Examples

In physics, energy can be defined as the capacity to do work. Just like there are many different ways of doing work, there are also different types of energy. Energy is a quantitative property. As per the law of conservation, energy can neither be...

15 Best Examples Of Potential Energy

The term ‘Potential Energy’ was coined by a Scottish mechanical engineer William Rankine in the 19tn century. It soon became one of the most influential variables in the formulas the describe our known universe. What Is Potential Energy...

What Is String Theory? A Simple Overview

String theory says that indivisible subatomic particles are made of tiny little strings vibrating in a specific pattern.  Each vibrational pattern corresponds to a different particle. Electron is nothing but a string vibrating in one pattern, and a...

What Is Hawking Radiation? Is It Proven?

Hawking radiation is thermal radiation spontaneously emitted by black holes, due to quantum effects near their event horizon.  It gradually decreases the rotational energy and mass of black holes. However, it’s just a theory; no such radiation...

A Whole New Way To Study Lunar Samples

Researchers use Atom Probe Tomography to analyze lunar soil. The technique uses only a single grain of soil to identify helium, pure iron, water, and products of space weathering.  This is the first time a sample extracted from the Moon has been...
