I am trying to understand orbital dynamics, in particular Langrange planetary equations.

I have come across the symbol X (chi) used as an orbital element. However, I do not know which element it is. Is it true anomaly? Mean anomaly? Any help is appreciated.

I am currently trying to learn about the physics of solar radiation pressure. I understand how radiation transfers momentum to a satellite, but I am a little unsure of how this affects eccentricity from a simple mathematical standpoint. Writing an answer and/or useful links would be helpful.

I am currently a freshman at Berkeley and am planning to be a physics major. I would like to do some sort of internship or research over the summer. However, most institutions give preference to juniors and seniors when it comes to undergraduate research. I currently have no research experience, but will try to get some for this spring. Are there any programs I catered to freshman physics majors that I can apply to? (Links would be helpful)

I am currently an undergrad (1st year) at a university in the United States, and I am planning to major in physics. I am currently learning German and have a great interest in living in continental Europe. I am considering the possibility of transferring to a school in Germany (or a nearby German speaking country). I am very interested in TU Munich or ETH Zurich. Is it feasible to transfer to one of these schools, and if so, how might I go about doing it? Please provide links!

I am currently studying German and was wondering if anyone would be able to proofread this German paragraph.

In Berkeley, träume ich manchmal von einem perfekten Leben. In mein perfekten Leben, habe ich einen Trauzimmer. In mein Trauzimmer, möchte ich einen großes Bett, einen Sessel, einen großes Fernseher, einen Laptop, aber gibt es keinen Wecker. Infolgedessen, kann ich am Nachmittag aufstehen. In mein perfekten Leben, ich habe einen kleinen und braunen und weißen Hund. Aber, ich möchte nicht eine Katze. Zusätzlich möchte viel Geld. Mit meinem Geld, kann ich ein Flugzeu einkaufen und ich kann nach Europa zu reisen. In Europa, kann ich Italienisch unde Französisch essen.

I recently purchased a macbook air and I want to put Windows 7 on it. I can get a free upgrade of Windows 7. What is the best way to get Win 7 on the computer? I was thinking of purchasing a version of XP or Vista and then using the upgrade to get to Win 7. Or could I install the preview of Windows 8 and degrade somehow to Windows 7?

I'm doing a project for a music class, and I need to find two songs that have been used on both sides of a war. For example, I have found Lili Marleen, which was played on both the German and British side during World War II. In addition, I would like there to be a good bit of information about the song, being that I have to write a paper about it. Please provide a couple of links if possible.

I have recently been accepted to the University of Illinois (Urbana Champaign), Georgia Tech, and UC Berkeley for undergraduate studies, and I want to major in physics. I live in Georgia, so Georgia Tech is very cheap. and have gotten in state tuition for UIUC. UIUC is in the top ten in physics. How much better would Berkeley be for me than UIUC or Georgia Tech?

I am currently taking a computer class and need help understanding this code and it would help if you could explain what is going in detail in these three classes.

I understand how to calculate half-lives but I don't understand why the rate of decay is proportional to the current amount. Please Explain. Thank you.

Here is my question:

My friend and I desire to construct a little machine called a supercritical dryer to experiment with aerogels (extremely "undense" solid like substances). However, we are both in high school and can not afford to spend $750 to $1500 to build this. Does anybody know any grants (or anything that will give us money) to build a supercritical dryer?

This is an answer:

Semiquas...

As far as I know CERN gives out grants for exactly this kind of work. Call them up in Geneva, they might help you out.

Does anybody have any idea what this commenter is talking about (like a link) because I can not find where CERN is giving grants away?

I have a 4.0 GPA plus whatever AP gives you. I take a lot of challenging classes. I do a lot of extracurricular activities. However, everybody that goes to MIT and Stanford have the same accomplishments. How do you get accepted then?

I am familiar with single variable calculus and understand some multivariable calculus. I am looking for a site that is easily comprehensible but also uses basic calculus.

I have been trying to use Moivre's theorem to find the answer by I just don't know what to do.
