    LaTeX How do you maintain Bibliography file for BibTex?

    Thanks Krylov for your reply. I never use Zotero for bookmarking web stuff, I only use it to on to capture academic content using the browser plugin. So far, its pretty good. It works nicely on amazon books, google books, google scholar, and even on webpages containing references to research...

    LaTeX How do you maintain Bibliography file for BibTex?

    Hi guys, I have several projects on my three computers which use bibliography. I maintain them manually, copying and pasting whatever is needed. Needless to say, this is becoming stupid now. I recently started using Zotero. It seems like a nice idea, I use the zotero plugin to save whatever I...

    Achievable orbit from launch location

    Thanks Russ. So you mean that the limiting factor is the fuel? Thanks Steamking. Well, that doesn't answer my question. But anyways, good links. Aha, that's what I think is the case. I agree, but the cost you mentioned is for changing the inclination while in an orbit. I am talking about...

    Achievable orbit from launch location

    Hi Astro gurus, Is there any limitation on the inclination of the achievable orbit because of the latitude of the launch location? For example, latitude of Baikonur is roughly 46° E. Does that limit somehow the inclinations of the orbits that can be achieved from Baikonur? I think there...

    How exactly does a gas turbine engine produce thrust?

    For a large bypass commercial turbofan, yes. For a general gas turbine engine, no. Fan is just a term. Anything that imparts kinetic energy to a fluid stream is a compressor. However, there are many people who would contend this definition. For those who do, its just a definition, nothing more...

    How exactly does a gas turbine engine produce thrust?

    There are two ways to look at it. First is the general momentum change equation which gives you the net force applied by the fluid on the control volume. The other is the pressure integral all over the wetted surface (gas flow path) inside the control volume. The key is to understand that both...

    How exactly does a gas turbine engine produce thrust?

    Yup. Just for reassurance, I checked up with the guys at work, and it is so. There might be a moment while revving up the engine during starting when the rotor experiences no axial force, but it is never the design intent to keep it so during the operation. If it were to be "balanced" (axially)...

    How exactly does a gas turbine engine produce thrust?

    Its good to know that at least somebody wants to know what is happening. Exactly. Just a minor addition though. Thrust is the net pressure integral over the surface of the balloon. Exactly. Yup. Exactly. Umm. No. The shaft is not "balanced" in the sense that you used. The compressor...

    No body is doing PDEs? :(

    Understanding PDEs Intuitively

    Hi I am looking for a good book on PDEs. By good, I mean geometrically intuitive. Something like H M Schey's book on vector calculus. I know a bit about solving PDEs, I know they are elliptic, hyperbolic or parabolic, characteristic equation defines the type & that's just about it. What I am...

    Exploring Research: What it Is and What it Means

    ... how do you know when to stop in a specific research topic?

    Exploring Research: What it Is and What it Means

    thanks wuli, but that's not what I meant. what I was(am) looking for was(is) what people in similar profession feel? How do you feel content with the lifestyle? What motivates you? how do you plan the next step? and most importantly, how do you know when to stop?

    Exploring Research: What it Is and What it Means

    what is research? how would you define it? what am I doing if I am researching? Ok, that's pretty vague. I am talking about academic research. I have been working in a so called Research & Development organization for past two years, and no doubt, I am loving it. I love the freedom, I love...
