Understanding Quantum Mechanics #8: The Tunnel Effect
"Have you heard that quantum mechanics is impossible to understand? You know what, that’s what I was told, too, when I was a student. But twenty years later, I think the reason so many people believe one cannot understand quantum mechanics is because they are constantly being told they can’t understand it."

Yes.
One can get a very good grasp on both GR and QM, without maths.
Using thought experiments.
But this immediately leads to the "foundations" questions. What does it all mean. What is actually going on when we say the wave function decoreheres?
To get a grip on these type of questions, we need to maths to evaluate several different theories.
@corlin I found 2 good books that helped me understand it much better were Hawking's "A brief history of time" and Michio Kaku's "Hyperspace"
@corlin Kaku's book is especially informative on the multidimensional aspects of quantum theory
@corlin I always found it helped me to adopt Einstein's "thought experiment" approach rather than get caught up and lost in the maths behind it all
