Hello there, I remember seeing a video demonstration a few years ago of this very strange type of GUI for that particular operating system. On the display monitor, there would be windows like usual, but the view could be rotated 360 degrees around to view other windows. If I remember...

I just saw the following game demonstration given by Will Wright, the creator of the Sims world. http://video.google.com/videoplay?docid=8372603330420559198&q=spore The game starts you off as a very simple organism in a pool of liquid with other organisms (controlled by another player). As...

Just reading a textbook and came across this interesting question: "a daring lab instructor in a demonstration dips his wettened fingers into molten lead (327C) and withdraws them quickly without getting burned. How is this possible?" I was thinking simply that the water on the fingers...

Hi , Please can I have some help with this demonstration: Let a#0 ( #= different) Show that if a x b = a x c and a.b=a.c, then b=c ( Hint: Cross both sides of the first equation with a) When I cross by a ( as the hint suggests) , I found 0=0 ?? thank you

I need an algebric proof of the theorem of similar triangles (C/c=A/a=B/b).

I have to do a demonstration to show convection in class. I was wondering what could be a simple experiment to set up in which I could show that convection exists. I've had a few ideas and am wondering if you could come up with any. :shy: Thanks, lcg

Hello all Do you guys know of any demonstrations or examples I could do to explain Bohr's Model to my class? I have to give a presentation. Any ideas are appreciated. Thanks :smile:

How do you prove this is a function? g: P(A) > P(A) g(X) = X^-1 X^-1 means inverse of X anyway, does anyone know how to do a formal demonstration for this?

Explain why pressure increaseds beneath a vertical column of water and how to calculate water pressure ate the base of the column. Include the effect of varying heights and column diameters. thanks mike

For physics, I had to write a report and show a demonstration on the magnetic field of the Earth. I already turned in the report and I have an idea about showing the field. I was thinking of sticking a strong magnet inside a rubber globe of the Earth and then putting paperclips on different...

I'm a high school senior interested in completing a science project. I'm wondering what knowledge is necessary for me to understand the interaction between coherent light( like a laser) and a uniform electric field with the ultimate goal of constructing a model. The project will be a type of...

I am a high school student, but I need some college level help. Ok, here's my problem. I plan on doing a an demonstration on theoretical physics. This is for a science fair. Now, I had an idea for about half a year, but it fell through. So my question is, is there an experiment (college...
