Waves can be described as propagating dynamic disturbances of one or more quantities. The scientific study of waves dates back to the 17th century, although its concept was around for much longer. There are many shapes and forms of waves that one...
In physics, waves refer to disturbances in a medium carrying energy without a net movement of particles. The two most common types of waves are electromagnetic and mechanical waves. Both transmit information, energy, and momentum, but they do not...
The past two centuries have produced some of the most incredible inventions ever developed in human history. Many significant ones came to life in America. From vaccines and medicines to electronic devices and deep space exploration, many American...
Nitric Acid is a strong acid with a PH of about 3.01. It is a ‘sticky’ molecule that readily absorbs to surfaces, specifically if there is water on the surface. The physical state of a pure nitric acid is a colorless liquid, but older...
Carbon nanotubes are cylindrical molecules made out of rolled-up sheets of graphene. They are the stiffest and strongest materials yet synthesized. They have unique electrical and thermal properties. These nanotubes can have a variety of...
The term ‘metal’ is derived from the Greek word ‘metallon,’ which means ‘to extract’ or mine from the ground. Our planet contains plenty of metal. In fact, out of 118 elements in the periodic table, about 95 are...
Benjamin Franklin gets all the credit for discovering electricity, but all he did was establish a link between lightning and electricity. Charles François Fay, Luigi Galvani, Alessandro Volta, Michael Faraday, Thomas Edison, and Nikola Tesla made...
The hardness of any mineral is defined by its Mohs scale number: harder the mineral, higher its Mohs number. The Mohs scale was devised by a German geologist and mineralogist Friedrich Mohs in 1812. It works by analyzing the ability of a material to...
Phosphoric acid is a corrosive inorganic acid with the chemical formula H3PO4. It’s a weak acid, available in a range of quantities, purities and reagent grades. In its pure form, phosphoric acid is a colorless solid. In less concentrated...
A British physicist named Ernest Rutherford described alpha particle for the first time in 1899. He also differentiated and named alpha and beta radiation. However, it wasn’t until 1928 that George Gamow solved the theory of alpha decay using...
