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 [...]
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.
