There’s a concept that’s crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It’s entropy, and it’s notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course [...]
Perpetual motion machines could totally transform our relationship with energy ... if only they worked. Ideas for perpetual machines all violate one or more laws of thermodynamics.
Matter is made of fundamental particles and these particles interact with each other according to a theory called the Standard Model. Watch this video from Ted-Ed to know more.
We actually don't know if time exists. This video from Ted shows why time puzzles scientists:
In this episode of the ABC’s classic science program, ‘Why Is It So?’, Professor Julius Sumner Miller re-attempts a favourite experiment, and things don’t quite go to plan. That's why we should all have faith in Physics.
Gravity is a force of attraction that pulls together all matter. The more matter something has, the greater the force of its gravity. Learn interesting facts about gravity by watching this video! https://www.facebook.com/ScienceNaturePage/videos/1399544610177793/
