The Large Hadron Collider is a decent example-- it's colliding protons together at an energy of 13 TeV, not because that's the ideal experiment to do, but because that's a feasible compromise.

Here is an example of an excellent upper level physics video. Sure, there are some bad ones online (you know who you are) but it is possible to learn all of the old physics with videos.

Consider, for example, that cats, consciousness, and stars are all made up of the particles and forces in the Standard Model of elementary particle physics.

Physics is how you put it all together to make sense of your materials, and wind up with a house, for example, instead of a collection of parts that could, in principle, be used to build something ...

Well, in physics there are a lot of theories but not many laws. A law has to be a summary about a phenomenon—like the laws of thermodynamics or Newton’s laws of motion.

The second law of thermodynamics says, in simple terms, entropy always increases. This principle explains, for example, why you can't unscramble an egg.

Wigner's Friend is a paradox in quantum physics that describes the states of two people: one conducts an experiment, and the other observes that first person. Traditionally, the thought experiment ...
