Does anyone know where, on the internet, I can find a bunch of the diagrams from the book? Google images didn't really have any decent sized ones.

Can we learn anything about the status of QG phenomenology by checking out the abstracts for the July talks? Bee Hossenfelder, who occasionally posts here, has organized a conference, set for 12-16 July, on Experimental Search for Quantum Gravity. Just as a side comment: a lot of conferences...

When viewing the light coming from distant galaxies, it is my understanding that there are 2 redshifts occurring, the doppler effect from the galaxies' peculiar motions, and the cosmological redshift from space itself expanding. For the cosmological redshift, I visualize a square of space...

This problem does not make sense to me and plus I keep getting a different answer: You have y=x^3 and x=y^3 these are rotated about x=-1. I put everything in terms of y and solved with respect to y. I set the problem like this: \pi\int_0^1{(1 +{\sqrt[3]{y})^{2}} - (1 + y^{3})^{2}}dy I foiled...

Hi This is a long story, I make it short: I am working in a project where I need to find a matrix defined by a third degree polynomial, the solution can be found iteratively using a gradient descent technique, I am using the golden section line search already implemented in MATLAB (with the...

I'm an adult in the finance industry with no science background, and I'd like some help understanding relativity. I'm reading Walter Isaacson's biography of Einstein, and while I know it's not the point of the book, I can't get my head around the passages concerning relativity and it's really...

What does everybody think of the new Google search results layout? http://bits.blogs.nytimes.com/2010/05/05/google-gives-its-search-results-a-facelift/ It's far too busy and distracting for me. The reason I've been using Google all these years was the simplicity of their search results...

Hello all, I am an undergraduate working on a project for water purification in search of a water soluble compound (organic/inorganic salt, gas), preferably of low molecular weight, which can attain solubility of more than 3 Molar at Room Temperature and Pressure (Temp can be more or less...

Recently I ran across http://academic.research.microsoft.com/" and found some interesting and valuable features. :wink: Especially it has some useful tools that may help you in writing papers, choosing conferences or journals to submit articles, getting to know scholar’s ranking and...

It took me a little while to wrap my head around circularly polarized light, or more specifically how this can be done "passively". Wikipedia didn't do much help until I found the article at Polarizer, if any of you were wondering how the new 3D movie technology works. My first question is...

Hello all, I'm a senior in Engineering Physics, about to graduate in May with a bachelors, and I'm looking for a job. I'm not sure where to look. What kinds of companies hire people like me (especially companies in Illinois)? The classes I've taken include the basic physics core (mechanics...

Greetings all. I graduated with a math degree about a decade ago, but what I'd really like to do is study physics. The problem is that I don't have great options locally, but my day job is going to keep me here, at least for now. I'm hoping to find something good in terms of online education...

Hi all, I am enrolled in an introductory signals and systems course at my university. I don't like talking down on my professors but in this case I can't help it. He is one of the worst teachers I have had in my life. I have visited his office hours but he's not really helpful in there...

About a year ago there was some buzz about a background noise that scientist Craig Hogan interpreted as possible evidence of the texture of space and confirmation of the holographic principle. I believe later on the noise was explained as misadjustment of the machine. Anybody aware of the last...

I am writing a programme which has to find specific cells with special properties. I don’t know where the cell are located by I have a pretty good idea so my programme can actually make qualified guesses. When I have guessed on a cell and it’s not the right one I have to check the cells lying...

Howdy, I'm completely not sure how to go about this problem. I feel like there is more than one way to approach this problem. I just know words can go forwards, backwards, and diagonal and just get stuck there. So here it is: What is the probability that a letter in a given position...

I am a senior thesis away from completing a B.S. in Astrophysics. I am very interested in a career in Plasma and Fusion Physics, and I live near 2 national labs where such research takes place. However, I have decided not to go to graduate school. I'm poor and I already owe over thirty thousand...

Hi All Is there a proof that all blind-memoryless search strategies are equivalent? By equivalent I mean that no blind-memoryless search strategy can outperform any other in terms of time to goal and domain coverage. It seems to me that this is intuitively true. How would I go about...

When perusing a file using the linux less command, and you use the less search command inside less, I would like to know how to make less not display the line containing the target search string as the very top line of the session window (very poor design). I want the target line to always be at...

Abstract This post introduces a holistic approach to the description of the physical reality. The solution, referred to as the Dynamic Universe (DU) [1], is based on a zero-energy balance of motion and gravitation in spherically closed space. The Dynamic Universe allows the derivation of all of...

How do I search for a phrase like "Principles of Relativity Physics" rather than it being interpretd as a number of keywords? Thanks

I came across another good search engine today looking for a datasheet, so I thought I'd try starting this thread for folks to post useful links. The links should be to technical content, and not to paid services. Good free datasheet search engine: http://www.datasheetpro.com/ Good way to...

Rather than hijack the help with C thread, discussion can continue here. Just like anything else, goto's can be used appropriately or inappropriately. Inappropriate use doesn't invalidate using goto's. I assume you mean one main loop per function, not per program. Take the case of a file...

I'm trying to write what is basically a search and replace script. Full disclosure: This IS a homework assignment, and my attempt is below. It is supposed to have a usage statement, which I think is pretty solid so far. The problem is at the end where I do that actual searching and replacing...

Homework Statement I am working on an assignment in which I have to add a method to my BST class which checks if a binary tree object is in fact a Binary Search tree. So (1) A left child must be smaller than the parent (2) A right child must be larger than the...

I'm wondering how it really is useful. The input for the, say 2-qubit, quantum computer that is running Grover's algoritm is |\Psi \rangle = (|1 \rangle + |2 \rangle + |3 \rangle + |4 \rangle) / \sqrt{4} And let us say we're looking the 3rd element in the so-called database. Now, Grover...
