I am interested in this subject. Theoretical Physics is cool.

This is what got me warned on Neopets

"Watch DrPhysicsA's YouTube videos for a great explanation." When the Neopocalypse happened, I made a thread saying everything I got warned for, and I got warned for that. It had censored it something like DrPh****sA. I got frozen afterwards haha.

But since I couldn't post the YouTube link, but can do here now, I will do so.

As Walter Lewin says, "they even make the mistake to think that physics is difficult. absolutely not true."
