    Introductory Probability/Information Theory textbook reccomendations

    Hey folks, I've been interested lately in reteaching myself probability as a foundation for information theory. I took an introductory course about 8 months ago and while I did fairly well, I don't feel like I took much intuition away from the course. Are there any recommendations on books or...

    Are All Waves Sinusoidal, or Are There Non-Sinusoidal Waveforms?

    It's somewhat true. If you've taken courses in signal analysis you might be aware of Fourier Analysis, which is a topic in mathematics where you can represent general functions in terms of sums of trigonometric functions. If you look at a square wave, for instance, you can visually create that...

    E vs K Diagrams: Understanding Crystal Momentum & Velocity

    I think my first question is just going to require me to think on it a bit. As for the second question, see, I can perform that exact derivation, no problem at all, but then I recall this: k = p/ħ = mv/ħ Is this only true for the free electron? My text is rather vague on the matter. But...

    E vs K Diagrams: Understanding Crystal Momentum & Velocity

    Unfortunately my physics upbringing has been really shoddy in terms of waves. I've taken to going back to my old physics text to read chapters on wave mechanics we never covered in class. So I don't have a truly intuitive understanding of wave vectors and that doesn't quite help.

    E vs K Diagrams: Understanding Crystal Momentum & Velocity

    *Hope this is in the right forum* This upcoming semester I'll be taking my first course in Semiconductor physics and I'm studying out of the textbook independently this summer to prepare myself. I've been learning about energy bands and I wanted to clarify a couple of concepts that my text...

    How Can Spacecraft Travel Faster Than Light?

    The speed of light is constant in all reference frames, which gives rise to relativity of speed, time and length, among other properties. No matter how fast you travel, the speed of light remains constant relative to observers in all reference frames.

    Photovoltaics, Electric motors ,Solar energy. Should i go for EE?

    EE and ME are both very broad fields, so it really depends on what parts of these you want to study. Photovoltaics has always been under EE as far as I know. If you want to work on the actual semiconductor elements, that would be especially under a Electro/Semiconductor Physics focus. If...

    What is the Origin of the Repelling Force Between Dark Energy and Matter?

    If I understand it correctly (and I don't think I do), dark energy is not related to any forces, such as gravity or the electromagnetic force. It's thought to be a property of the universe itself, in essence the "fabric" of space-time stretching itself out due to quantum fluctuations. So there...

    Transferring to College: EE Advice for UH Manoa Junior

    Haha, fair enough, and your advice is greatly appreciated! Is there any good resource for finding other good schools to look at for EE programs?

    Precalculus review or Calculus 1

    The University of New Brunswick has a beautiful set of exercises to help check if your algebra and trigonometry is up to snuff for passing calculus. If you can work all the examples and make sense of them you should be reasonably prepared to jump straight into calculus...

    Transferring to College: EE Advice for UH Manoa Junior

    My biggest focus is the quality and quantity of VLSI and VLSI-related courses, as well as opportunities to work under professors on research projects, as well as finding a school that I can actually get accepted to :P I've been considering finishing and then going to grad school on the...

    Transferring to College: EE Advice for UH Manoa Junior

    Aloha! I'm entering my Junior year at the University of Hawaii at Manoa and I'm considering transferring to another school. When I applied to college I never really considered schools too carefully and ultimately settled at UH, my fall back. It's a decent school, and we have some amazing...
