Quantum dots are tiny semiconductor particles, just a few nanometers in size, that have unique optical and electronic properties due to quantum mechanics. They are sometimes referred to as “artificial atoms” because their size is comparable to the wavelength of visible light, leading to quantized energy levels that influence their behavior. Here’s a breakdown of Read more…
The Earth’s magnetic field is generated by the movement of molten iron and other metals in its outer core through a process known as the geodynamo. Here’s a simplified explanation of how this process works: Convection Currents: The outer core is made of liquid iron and nickel. Heat from the inner core and the mantle Read more…
Lateral thinking, a term coined by Edward de Bono, refers to a problem-solving approach that involves thinking outside traditional or linear patterns to arrive at creative and unconventional solutions.

The wet bulb temperature is a measure of air temperature that reflects the cooling effect of evaporation. It’s determined by taking the temperature of a thermometer with its bulb wrapped in a water-saturated cloth, which is then exposed to air. As water evaporates from the cloth, it cools the thermometer, and the resulting temperature reading Read more…
