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…
