Consider the following figure:
Let us suppose we were at some point in gaseous phase. Can we go from gaseous to liquid phase by moving about critical point continuously?
Why isn’t any critical point in solid liquid coexistence curve? Can we move from liquid phase to solid phase continuously? If ...
I was watching a waterfall in the Austrian Alps. There were thousands of water droplets falling down, splattering on the stones below. I thought - how does nature find out so quickly where each droplet of water should go?
To find out what happens to a falling droplet of water, one can use the law...
Complex numbers are often used in Physics especially in Electrical Circuits to analyze them as they are easy to move around like phasors. They make the processes easy but isn't it kind of amusing to use something which has no other real world analogous meaning to my knowledge being used to solve ...
The ideas of dark matter and dark energy are mind blowing.
Why is it said that dark matter overcomes dark energy in galaxies but it loses the battle in intergalactic space? In other words, why is dark energy dominant between galaxies but not inside galaxies?
I can understand why, if the speed of light is invariant, a photon clock would tick slower. I find this explanation very useful in terms of introducing the idea of time dilation (also because it allows for the Lorentz formula to be derived intuitively, only using Pythagora's Theorem).
But this ap...
