First and foremost, I read CSS & HTML & a bit of XHTML before I asked this question. I read them in 2 sites, DaveSite.com & W3Schools.org
Can somebody help me whether how to code this picture?
I would really appreciate it, thanks!:approve:

Hello Gals,
I know what a scalar is.
I know what a vector is.
I know what a linear transformation is.
But what in the name of sweet aunt petunia is a rank 3 tensor?

Hi,
I have been wondering why we can consider d(phi)/dt when we are in Schrödinger picture (phi is just the usual scalar field here). Isn't this 0 as operators do not depend on time in this picture? However then how does it make sense to talk about the conjugate momentum in this picture which...
How did this happen!? Weird picture!
So yeah... I was at the bowling alley and someone took this picture: http://a37.ac-images.myspacecdn.com/images01/38/l_81ee85d7d2e5ca216a96f823bb524cfc.jpg"
This is NOT photoshopped. I could see an explanation if it were blurred, but the edges of...
I think I heard from a Nobel Laurete in Physics that from the Electron microscope we were able to see the picture of a real atom for the first time in the 70s. But my chemistry textbook written in 2000 said that no one has actually seen an atom. What is going on?
Help please, is there such a thing as a wireless web cam that i can just use
with out any mods or additions to my desk top?
I need one with good picture and audio quality, and i need it to work 4yrds
from the desk top.
If there is no such thing can some one recommend a standard one for up to £50?
As expected, it was difficult to vote in this one. Just what criteria does one use? The best bad picture? The worst looking picture? Whatever it was, here are the finalists in this contest. Good luck!

OK, if you've read this in Physics Today or some other publications, you should disqualify yourself.
This is one of the most famous picture of Enrico Fermi. Yet, this picture has been a constant 'debate' among many physicists and science historians. Can you spot what is the issue with this...
Bad Picture!
This time, the theme is pictures that did not turn out, technically, as well as it should. Overexposed, underexposed, too dark, blurry, finger-in-picture, etc. all qualify. Note: such accidents should not be done deliberately just to qualify for this contest! So go through your...

This is an old snapshot I found at the swap meet:
All it says on the back is "summer 1948".

This is kind of random, but I am wondering if this picture of US soldiers standing ready to receive the bodies of 5 American casualties in the GWOT (I'm not sure OIF or OEF) shows an explosion in the background.

So I downloaded a NASA Blue Marble topografical image of Earth (2.4GB when I downed it, I decompressed and... wtf, 10GB+). Now I have no idea how to view the resulting .bin picture. I tried to somehow import the data to Matlab, because I heard that program can somehow do the trick, but it went...
Could someone help me find the length in cm of the lines between the points in the picture attached.
The 3 angles around point 6 are 120 degrees each. This is also the case for point 8 which is linked to point 2, 3 and 7.

So, the thermal radiation power off a surface is P=\sigma AT^4.

Can you elaborate on linear and picture thinking process. Linear as being a step-by-step process, and picture thinking processes multiples "pictures" simultaniously. Which thinking procecss might make the person smarter, successful?

Does anyone know where i can find a picture example of an image that is similar to the one projected unto the retina? The whole inverted, curved, non constant coloured dealy. Do such examples even exist, is it even possible to construct them?
Thanks
I have had two professors over the course of my academic career take a picture of each student to get know each of us, match a face to a name I guess. But both of these professors were kind of odd to begin with and both were male and math teachers. The whole prospect kind of creeps me out...

Picture a small mass orbiting around a large mass. Now picture both masses at rest, but the large one is spinning. They are both the same system but viewed from different frames, Newtonian gravity says nothing about the angular momentum of the larger mass, so in the second referance frame it...

I don't understand how one visualizes in row pictures of equations. There is an example in the book:
With A=I(the identity matrix)
1x+0y+0z= 2
0x+1y+0z= 3
0x+0y+1z= 4
They drew these in the xyz plane. I don't know how they did this, can someone explain me that?
