I was a physics major, so there were tons of physics concepts.

Most of which, you know, quantum mechanics and things which are not relevant to anyone outside of physics, but some really are.

So for example, the concept of critical mass came from physics, and kind of it's the nuclear material needed for a nuclear bomb.

But it's really useful outside of physics in investing, in products, in entrepreneurship.

Okay.

Um, what, what's your experience with that been in terms of like using different models and testing, you know, testing out the different models and sort of getting that experience.
