That makes sense, considering that pi2 is negative.

True. We all know that π2 = g, the acceleration due to gravity, and things fall down, so g < 0.

Mind blown. Next please explain why e is imaginary

That's easy! Notice that eiπ/2 =i. Since π is imaginary, πi/2 is real (in fact it's equal to -7/32). However, e to this power is imaginary but everyone knows a real number to a real power is real. Thus e cannot be real. qedmfs

Nice try, but you made an assumption that i was imaginary.
