A car at rest remains as such unless the engine forces the wheels to rotate and initiate its motion. The same car requires brakes for it to achieve rest state. Let’s think of a hypothetical…

Gas molecules in the solution (present in dissolved state) and those in the gaseous state are in dynamic equilibrium with each other. Though the concentrations of gas in the dissolved and undissolved state remains constant there…

The last article described what decompression sickness is and also shed light on concepts essential to understand the underlying science. This article focuses on how Henry’s law and the partial pressures come to play in deep…

Taravana syndrome, a disorder that is often reported in Polynesian divers. These divers make 50 m dives just by holding their breath. Taravana sickness is later deciphered to be decompression sickness. The sickness has something do…

The glory of atomic force microscopy and its method of working were discussed in the last article. However there were questions unanswered. How does one detect tiny motion in the tip caused due to forces exerted…

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…

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…

As we have discussed during our Physics tuition classes, diodes are mostly made from semiconductors like, germanium and silicon. Diodes allow one direction flow of electric current, however, how do so can vary from…

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…
