Hi everyone. I'm in my last semester of my BSEE degree. I want to get a decent job when I graduate in May. On paper I have a lot of things going for me, but my head is a total mess right now when I start thinking about it. I'm really scared I won't find anything, or if I do, something I...
Is there a way to find detailed informations on chemical structure and mechanical properties of commercialy available materials? I am writing a thesis on ceramic adhesives: all literature I've found talks about "castable refractory adhesives" (because of ASTM classifications). However, it is...
Hello everybody,
For a long time now I have been trying to find the very best thing to write with. I spend most of my time studying and solving math and physics problems so naturally pens and markers are a huge part of my life. I like to write with multi-colored pens as it helps me keep my...
Please Help With My College Search!
So, I am currently a Junior at my high school and, although you never know for sure right now, I am pretty positive that I would like to do a career in the Astro Physics/Cosmology area. I currently have a 4.22 GPA (I am in honor classes) and am not planning...
The Chinese remainder theorem tells us that the system of equations:
\begin{align}
x &\equiv a_1 \pmod{n_1} \\
x &\equiv a_2 \pmod{n_2} \\
&\vdots \\
x &\equiv a_k \pmod{n_k}
\end{align}
Uniquely determines all numbers in the range:
X<N=n_1n_2\ldots n_k
and that all solutions are...
Does anyone remember a program (or know of something similar!) which, given a compilation of data, would search for equations which best fit the data?

Hi there,
I have a problem for work that is stirring up lots of memories of University Math courses, and I need help!
I work in search engine optimization, and search engines use logarithmic scales to value pages and websites. I'm using a tool that mimics those scales and assigns a number...
Can we learn anything about the status of QG phenomenology by checking out the abstracts for the July talks?

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.

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

What does everybody think of the new Google search results layout?

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...

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.

Hi all,
I just started signing up for my GREs, and when they started asking for institutions to which my scores should be sent, I froze up and realized that I hadn't really nailed down my grad school choices yet. Eek! Some amount of Google-time later, this forum seems like it would be a good...

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...
