    E-field of a laser pulse and Intensity

    Hi, What is the equation for a E field of a single pulse of a laser? If that laser is shined onto say a grating spectroscope (square law detector), how can I go about deriving an expression for Intensity as a function of frequency at the output of the spectroscope? I know that the square...

    MATLAB MATLAB: alternative to CSAPE function?

    MATLAB: alternative to CSAPE function? (Aerospace application) Hi, I need it to spline fit an airfoil. This function is special because it has "end conditions". So the trailing edge will remain intact. I am looking for an alternative because I don't have Spline Toolbox and this is the only...

    Billiards - Predicting Optimal Trajectories?

    I believe that. Only because its a problem of velocity lost due to friction. I don't think so. I would even believe that I might need a supercomputer to calculate it. But there has to be a way. I mean, the laws are used to make pool simulation games in the first place. Exactly. But, that's...

    Billiards - Predicting Optimal Trajectories?

    Is there a program code or game or applet that will allow me to predict.. basically, the initial and standard state of the table. Say, I give it initial positions. Given the angle and magnitude of the cue ball, it should tell me what the final positions of each balls are. Which brings me to...

    What Is Jet Engine Inlet Distortion?

    I've calculated the distortions and submitted the assignment. I got numbers like 0.00196 (fan face). But I have no idea if its correct because I have no reference. I'll figure out when I get it back. Thanks for help Cyrus and FredGarvin. Neo

    What Is Jet Engine Inlet Distortion?

    I see. So I can just use the formula. Radial distortion: use data for same rake, different taps (from center to outwards) Circumferential: same pressure tap, different rakes Across fan face: ? What are some typical values for inlet distortion?

    What Is Jet Engine Inlet Distortion?

    Exactly! You know my problem. I have no idea what they are talking about! What's distortion and what's it got to do with pressure? (Google search results in very unrelated concepts) Neo

    What Is Jet Engine Inlet Distortion?

    (This is a homework/lab assignment but thought it better suits in this category) Hi, This is a scaled model and I am given the pressure tap locations on each rakes. Also given is the pressure data. Inlet distortion formula is given by: Pdist = (Pmax - Pmin)/Pavg Question is to find...

    Why is there a decline in interest in science majors among US citizens?

    Dr Transport is very right. As regarding to the declining interest in science, my belief is that in the society there happens to be a distinction as to what/who is "cool" and what/who is not. Since elementary and high school, students who are good at sports and who participate in lot of...

    Why is there a decline in interest in science majors among US citizens?

    Sorry for the misleading title. I've changed it now. But why is this happening? Is it because other fields seem to be more beneficial?

    Why is there a decline in interest in science majors among US citizens?

    Decline in the number of US Citizens interested in Science Majors! Why? [FONT="Times New Roman"][SIZE="4"]The National Science Board warned of a “troubling decline” in the number of U.S. citizens studying to become scientists and engineers, even as the number of jobs requiring science and...

    What can I do to learn more about the life of a scientist?

    After reading the replies, I would like to make some things clear, although some other replies did answer my question. I am not afraid of labor; I know what working with physics is like. Neither I want to go into that field for making lots of money. I really like it. I want to dedicate myself...

    What can I do to learn more about the life of a scientist?

    I love all aspects of science. But, I like physics more than bio, chemistry etc. Being a scientist is my basic goal however I can't express my desire b'coz it will seem like I am bragging or something. But, the main problem is that I don't know how to enter the field. Being a physicist is the...
