Thanks for all your suggestions. Evo, when I do right click and open in new window, the page just freezes and I have to ctrl alt del to carry on, just as if I had left clicked it. The computers running fine in itself though. I'll certainly download what you've suggested though guys. Cheers

Thanks for the suggestion but the mouse and keyboard are working like a dream. I just find it very strange because it was working perfect yesterday and when I loaded up this morning it starts playing silly buggers!

Hi, I am currently experiencing problems on my computer such that, if somone sends me a web page link, nothing happens when I click on it. Same goes for if I try and open links on web pages that would take me to another site. Has anyone got any suggestions as to remedy this problem please or...

If the sun at temperature 6000K emits onto an asteroid 350million km away, what is the temperature of the asteroid assuming it is a black body? Any suggestions how to go about this please? :confused: :confused:

Yeah that's the one mate.

OK so I'm revising for my finals and have spent 14 hrs revising today and cannot for the life of me get the very last part of Qn 3 on the attached link. It begins "By minimising the potential energy..." Could someone throw me a lifeline and explain what I need to do because my exam's in less...

Could someone please direct me to a good web page or comment on the main difference between the euler lagrange eqn and lagranges eqn of motion. I'm struggling to differentiate between the two... Also, I'm struggling to grasp the concept of Lagrange density - when does one introduce this into...

Cheers mate, I was using the multipole expansion formula of phi(r) in spherical polars. My working matches what you have said so thanks for confirming that! :smile:

I'm having a lot of difficulty calculating the monopole and dipole moments for a dielectric sphere with surface charge of the form, sigma(theta)=sigma(0)cos(theta) If surface charge wasn't present and it was just a point charge I would be OK but I need a few pointers on how to do it with...

OK, that's nice and clear now. Thanks for your reply CRGreathouse!

Hi there, I'm a bit stuck and was hoping somebody could give me a couple of pointers... A lecturer wages that at least one pair of students in his class have birthdays on the same day. What is the minimum number of students in his class for him to be likely to win the bet? I have assumed...

Thanks for your responses guys they've been most helpful!

Hi there, I am currently trying to write an essay on "Was the cuban missile crisis the closest the world ever came to nuclear war?" I was hoping you crazy cats could suggest other minor or major historical conflicts... I already have the Quemoy-Matsu crisis and the India-Pakistan ones...
