I'm trying to gain a better understanding of how light, pigment, filters and our retinas interact as part of an investigation into colour theory. However my education in physics never went farther than what was necessary for A-level biology. My main interest is in the following hypothetical ( Read more... )

This article discusses a long term study of children that looks at how boys and girls are influenced by their parents in their performance and interest in math. They found that girls' interest in math decreases as their fathers' gender stereotypes increase, whereas boys' interest in math increases as their fathers' gender stereotypes increase ( Read more... )

I'm currently revising for my gcse o level exams in october. sigh,

anyways, im revising pressure now and I got a qns. I'm sure my teacher covered this before but i kinda forgot.

Is the pressure on the position X on the RIGHT diagram below equal to the atmospheric pressure? or isit equals to:

atmospheric pressure + the height of mercury from the ( Read more... )

I read this mini problem in my copy of Ny Teknik (="New Technology") last night, and thought it was fun so I am sharing it here. The article is in Swedish, since the paper is a Swedish one, so I will give a translation for those of you who don't speak Swedish ( under the cut. )

I super pissed at my undergrad institution. I just found out that they didn't send my transcript to the masters program I'm applying to. I sent them the order 1.5 months ago and they cashed the check and the masters program still doesn't have it ( Read more... )

I found this article today about how the name of a child influences whether they will study math or physics. They say that girls with more feminine names are less likely to study math or physics at a higher level. What do people think?http://www.

This is for all you grad students out there. I'm going to be starting grad school for physics and I'm getting a new laptop as a graduation present. I'm not superknowledgable about computers and I was wondering what you guys would recommend for physics grad studenty stuff. Thanks!

Plaskett's binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. This means that the masses of the two stars are equal. If the orbital velocity of each star is 220 km/s and the orbital period of each is 14.4 days, find the mass M of each star.

Ever wondered what the guys in the International Space Station get up to? This link was sent to me by one of the postdocs in my department. So cool :)
