I'm working on induction at the moment, and the math makes sense, but Lenz's Law is giving me trouble. Does anyone have an easier way (relatively) of remembering the directions of emf? Any advice is appreciated.
So currently what I'm interested in is astrophysics and plan on getting my masters. I'd like the input of anyone with experience in the field. Whats the job market for astrophysics like? What type of jobs are available? What companies would I be wanting to look at if I wanted a research job? Is...
So how do we determine distances of objects in space? I think I understand using the parallax to calculate distances of relatively nearby objects, but what about further off objects?
So, I'm still a bit new to the realm of physics but I was discussing theorized particles with my professor the other day and came to the conclusion, if gravitons do exist, could anti-gravitons be an explanation for why the universe is expanding? I was reading around and came across a similar...
