Where to start? Here's an excellent 8 min. video that lays out a "map" of all known physics. The good stuff, of course, is hiding in the "Chasm of Ignorance." That's where the cool stuff of the future will show up. Stay tuned:

(Besides the videos below, you will quickly find an endless assortment of linked and recommended videos online. The physics field is vast. Here, we are tending to concentrate more on quantum than anything else, as that is itself still a work in progress, and holds the most promise for philosophical breakthroughs in the future.)
The Original Double Slit experiment (Veritasium) 8 min:

(This, the original experiment from 1803, demonstrated that light acted as a wave, where it had been previously thought, through Newton's influence, to consist of particles. But there was more to light than that, as was demonstrated by later and more sophisticated versions of the Double Slit.)
