## The Harvard Swampland Initiative

The past few years I’ve been noticing more and more claims like this one, supposedly finding a way to “connect string theory to experiment”. When you look into such claims you don’t find anything at all like a conventional experiment/theory … Continue reading

## Physical Intuition vs. “Math”

A common theme in discussions online of the problems of fundamental theoretical physics is that the subject has gotten “lost in math”, losing touch with “physical intuition”. In such discussions, when people refer to “math” it’s hard to figure out … Continue reading
