Scanning electron and transmission electron microscope
Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.

The SEM or scanning electron microscope has become more admired than the TEM or transmission electron microscope as it can generate images of high resolution, better clarity and three dimensional qualities and needs less sample preparation.
Meissner effect (W. Meissner; 1933): The reduction of the magnetic flux in a superconducting metal whenever it is cooled beneath the transition temperature. That is the superconducting materials imitate magnetic fields.
Landauer's principle: The principle which defines that it doesn't explicitly take energy to calculate data, however instead it takes energy to remove any data, as erasure is a vital step in computation.
How do I find out a maximum current flowing through a resistor with just the resistance of the resistor and it's power rating?
Tau-theta paradox (1950s): Whenever two distinct kinds of kaons, tau and theta (nowadays tau refers to a totally different particle) decay, tau decays into three particles, whereas the theta decays into two. The tau and theta vary onl
Tachyon: The purely speculative particle that is supposed to travel faster than light. According to Sir Einstein's equations of special relativity, a particle with imaginary rest mass and a velocity more than c would contain a real momentum and energy

Refraction law: For a wave-front travelling via a boundary among two media, the first with a refractive index of n1, and the other with one of n2, the angle of incidence theta is associated to the angle of refraction phi by:
