Ah my mistake. Reading his wikipedia right now, it says, "he transferred to the University of Pennsylvania, an Ivy League university in Philadelphia, where he earned two degrees: a Bachelor of Arts in physics, and a Bachelor of Science in economics from the university's Wharton School." Had no idea Bachelor of Arts in physics was a thing. But economics is Bachelor of Science? What happened there? Is that a mistake? Physics is a hard science.
Yeah, it's my perception that the BA for sciences are for people that want to teach high school and lower. That's how i got a math degree. I'm not sure if i could've handled any applied math. Abstract algebra kicked my ass twice, and diff eq took me a couple of months in to get comfortable with.
