I am a PhD in physics, but this is the first time that I learn how the Schodinger equation was derived. The physics idea left behind is what we should learn. My teachers never covered the topic with such clarity in their lectures. The idea is very inspiring.
Hydrophobic/hydrophilic surfaces are of great interest for many research. However, we found that the contact-angle of a liquid droplet critically depends on the contact-electrification induced interface charges. This is an important progress in the field and it may change your

If the universe were the size of our earth, the solar system would be the size of a grain of sand. The universe is far more mystery than what we know and what we can imagin. It is very possible that some of the postulations and theories about universe could be wrong.
