Classification of numbers: Numbers came into existence because of the need of counts.   We encounter the numbers or use them in our day to day lives.   Numbers are broadly classified into real numbers and imaginary numbers .  We commonly use the real numbers in our day to day life whereas we are not much familiar with the imaginary numbers. But imaginary numbers also have an integral part to play with, when it comes to quadratic equations, technology, electricity, etc., Significance of 'i': Imaginary numbers are usually represented by 'i' Imaginary numbers are NOT imaginary. They exists and has it's own applications. Euler gave the symbol 'i' for roots of negative numbers. When we take the roots of negative numbers, we get an error reply.  So to get the result of negative roots, the real numbers are multiplied by 'i' =   √-1   Where 'i' is the 90 degree rotation to the real number axis. Since 'i' has the property of oscillatory...

  "There is nothing more deceptive than an obvious fact "   - Cheryl Powers 1. Triple Point: Water can exist in liquid, gas and solid form at the same time. The single combination of pressure (approx. 611 pa) nd temperature (273K) at which liquid water, solid ice and water vapor can coexist in a stable equilibrium. 2. Astronaut's height in space! Astronauts height increases in space. When astronauts enter into the outer space from the Earth, the gravity that acts on them is low and after a certain limit the gravity that acts on them becomes zero . Therefore the downward force that acts on their bones will be zero or very low. So the height of that person in space increases 2 inches . But when they return back to Earth, they will again experience the gravity and their height becomes normal again. 3. Einstein against Quantum Mechanics! Einstein contributed many works in different fields of physics. Though he is known for his contributions to the development of quantum theo...
