Here is - in my opinion - a critically underrated and undersubbed YouTube channel. Alpha Phoenix, or Brian, makes pretty top notch engineering and science videos, mostly on the topic of material science. He can be a little cringe at times but honestly I love his content. Thought it would be a worthy share here

My favourite video, where he uses the Fizeau apparatus to calculate the speed of light within 99.3% accuracy
