Atlas Definition and 63 Threads

And can the two run simultaneously?

Hello, I want to show the following little exercise: If we have a manifold M and a atlas A of M, s.t. for all coordinate maps x,y \in A: det \; (d(x\circ y^{-1})<0). Then there is a atlas A' s.t. for all x',y': (det \; d(x\circ y'^{-1})>0) I try to change the coordinate maps by...

Eurostar: Accepted approach in search of the Higgs, applies to ATLAS: The physicists: Five videos so far, more to come, subscribe here: http://www.collidingparticles.com/subscribe/index.html" for new releases. http://www.collidingparticles.com/episode01.html"...

First, the assembly, time lapsed of course... http://www.youtube.com/watch?v=kVrUR_SOykk&feature=related" This is a blow up of the Transition Radiation, Semi-conductor and Pixel Detectors, innermost Atlas detectors. Description of layers of detectors and what each one is...

When protons collide in ATLAS, it shows some of the particles in close proximity to the collision with a curved trajectory. The cool thing is, some curve away from the ground. I’m trying to understand what influences this trajectory. If anyone can give me some info to help that would be great...

Homework Statement Find an atlas and coordinates for a torus T^2 = S^1 X S Homework Equations The Attempt at a Solution I know that an atlas on a manifold M is a collection of charts whose domains cover M, but i am not sure how to start this one mathematically.

Considering the Atlas experiment, which are the basic theoretical decisions someone must take in order to create an effective calorimeter? In other words, which are the basic problems that someone must solve to achieve the best possible effectiveness? For example, the high temperature problem...

Hey, I have to write a Lab Report that is based on the ATLAS electromagnetic calorimeter. One of the topics I have to write about is "the detector technology used". I'm unsure of what this could refer to, can anyone help?!

Ok folks, I have a bunch of friends who believe the high particle collieder will cause a black hole or that the atlas experiment team try to make a big bang or so called small universe. I love to hear everyones opinions and thoughts about this rumor or stupid crackpot theories on how the world...

I just placed an order for http://www.telescope.com/shopping/product/detailmain.jsp?itemID=194382&itemType=PRODUCT&iMainCat=4&iSubCat=10&iProductID=194382" Orion Atlas 11. With some luck, it may arrive by this weekend. Awesome.

I was thinking about something yesterday and I couldn't quite figure it out. It's about the question if an atlas is a countable set. Because we know that every manifold is second countable, so it has a countable basis. But does every element of the basis fit inside a chart domain? If that's the...

An atlas of environmental change compiled by the United Nations reveals some of the dramatic transformations that are occurring to our planet. It compares and contrasts satellite images taken over the past few decades with contemporary ones. These highlight in vivid detail the striking...

Not forcing a topic just to be the first to post a review of an astronomy book or anything, I just thought perhaps some of you may be interested in one of the most helpful star atlases i have used, to-date. It is The Great Atlas of the STARS by Serge Brunier, photographs by Akira Fujii. It...
