What happens when you leave a bowl of hot soup on a table? It gets cold after some time due to the loss of heat to the surrounding air. And that’s (transfer of heat) what we call convection. There are three types of heat transfer: radiation...
Most of the modern devices use sensors to monitor and control various physical quantities like pressure, temperatures, humidity, light intensity, direction, etc. One of such sensors, used to measure the acceleration of the devices, is called the...
Nikola Tesla was, without a doubt, one of the greatest inventors in history. Born in 1856 to a Serbian family, Tesla had always been ahead of his time. He graduated school a year early, excelled in the university where he studied electrical...
What actually is Pluto? Is it a planet or just another trans-Neptunian object (dwarf planet)? The uncertainty over Pluto’s planethood is, without a doubt, one of the most flaring issues among researchers and space fanatics. Scientists have...
