Hello again PF! I think I ask excessively often here so I tried my best to search in google. The result I got was this: http://superstringtheory.com/math/math1.html Well, that appears as all the math there is (no offense to mathematicians)! Likely the field of super string theory is the most...

We all know that 12/25 + 18/30 is not 30/55 yet students are happily told that they got 12 out of 25 in their first maths test and 18 out of 30 in their second maths test giving a total of 30 out of 55 So in this case 12/25 and 18/30 is 30/55 So should we be surprised when students say...

I'm a junior in high school taking calculus 1 at a local junior college, and I am getting quite bored with how very simplistic calculus seems to be in calculus 1. To me it just feels like an expansion upon algebra and trig with a few new twists, but nothing that actually requires me to use my...

"Society of Physics Students" or other physics society worth it? I have seen the Society of Physics Students mentioned more than the other societies, but I am wondering if you really get anything out of joining them or if it's just something to fluff your resume with for grad schools? Also, is...

(a) since $n(U)=120$ and the intersections showing $8,7$ and $4$ added is $19$ then $\displaystyle\frac{19}{120}$ is the probability of studying exactly $2$ languages (b) since $n(J)=35$ then subtracting $8,5,7$ would be $15$ so $\displaystyle\frac{15}{120}=\frac{1}{8}$ would be probability of...

So I joined the Society of Physics Students during my sophomore year of college, and I am a junior right now. I am wondering, how long does my membership of the society last? Do I have to renew it in the future if I so choose or is it for life? Thanks.

A few years after I finished high school, I took a few subjects at my local community college with no real major in mind, didn't do very well and then left school for almost six years.
