Atomic Force Microscope Part 1

Seemingly ugly, the black and white logo of IBM is a symbol of nanotechnology’s sophistication over the years. The lines in the logo are actually 5-base-long strands of DNA (Deoxyribose nucleic acid). Before we ponder over IBM’s obsession with making their logos using DNA’s and atoms, let's discuss how IBM has achieved the…

Types of Matter

Speaking Sub-atomically In the early definitions of matter, everything made of molecules was included. It was later expanded to incorporate everything that contains subatomic particles. Currently, ordinary matter is considered to be anything made up of quarks, neutrinos and electrons - but certain materials aren’t made of quarks, although they…

Angular Acceleration Explained

Generally, quantities are classified as scalar or vector. Scalar quantities are those quantities which have only magnitude while vector quantities are those which have both direction of motion and magnitude. Each and every scalar quantity is related to a corresponding vector quantity. Linear acceleration and velocity from the scalar class…

How Sound Travels

Sound is a movement of rarefaction and pressure waves that can travel for prolonged distances. It’s produced by the particles’ vibration in a given medium; a medium can be defined as the material through which the sound travels. A medium must be present sound waves to propagate. There is a…

Rutherford’s Atomic Theory

James Chadwick was an English physicist, well known for his discovering neutrons in the year 1932. He acquired a Nobel Prize in the physics discipline in the year 1935 for this substantial discovery. Throughout his lifetime, he closely worked with exceptional scientists like Johannes "Hans" Wilhelm Geiger and Ernest Rutherford,…
