Hey everyone, I'm looking for a .pdf viewer that let's you comment on the file you're viewing, mark words or lines (such as if you were to have a proper marker and a sheet of paper) and all kinds of stuff like that which are useful, but not really supported with the (free) Adobe Acrobat Reader...

Hello, I am a Mechanical and Aerospace Engineering major in my senior year and I enjoy it but I'm starting to think that I might be happier doing Software Engineering. as a note: I'm not really that interested in a career as computer programmer because they seem to make half the income as SE...

Hi I want to make a high accuracy collimator lens, such that it collimates ( with divergence angle < 1 micron) a beam of light coming from the focal plane but from off axis points as well ( -delta to + delta, where delta is in microns). Sugest some suitable softwares (along with the link)...

Hello everyone! I'm looking for a software in which i could simulate physical experiments from the field of classical physics. Before you start recommending matlab, i would like the software to be, well, a bit "higher" :) What i mean by that is that is should simulate the model in 3d...

I am designing web software to interface to \LaTeX, Maxima and R. What I wanted to get feedback about is: 1) Security issues which may arise from calling Maxima and R from the web. The interface is going to be a AJAX GUI and not a raw command-line input form so I will be able to filter...

I hope this is the correct forum, I have read most of the rules and it seemed the best place for this post! I have a Chemical Engineering problem, in the design of a reactor which has a design equation which I know to be a 5th order polynomial. Deriving this from first principles takes a lot...

I've been delving a little deeper into electrical theory in terms of noise and low signal measurement as I'm working on some rather sensitive stuff and the back of my napkin calculations isn't cutting it anymore as I need to account for things like opamp input bias, voltage offset, etc. I...

When I read on a computer screen I like to use the scroll wheel on the mouse but when I do the text jumps and it is easy to loose my place when reading some text. Would it be hard to have a mouse control panel adjustment for the scroll wheel that could be set so as to allow the window to move up...
