Does this "secret Tesla generator" really work? I came across this site making claims about this Tesla secret generator, and I am wondering if anyone has any advice on whether or not this actually works. The video on the site shows it actually working but I want some more insight on this before...

The only requirement is that the pure random numbers generated have to be purely random to its creator, not for some other inferior species. (To keep Evo happy, a super being is someone who is omniscient and omnipotent.)

Hi, I've read quite a few times now in group theory and QFT books that [X_i,Y_j]=i\epsilon_{ijk}Y_k can be regarded as saying that \vec{Y} , the vector of boost generators transforms as a vector under rotations (where X are SO(3) generators). I don't really understand why this implies...

First, let me just say that I am very new to electrical engineering. It is something that I started teaching myself mere months ago. So, basically, it is probably best that you guys assume I know nothing. As I have expanded my knowledge, I have built some little things. For instance, an LED...

I was reading an article on spread spectrum clock generator here - http://www.maxim-ic.com/app-notes/index.mvp/id/1995 Wouldn't spreading the frequency from the center frequency affect the data transfer? In case of a CPU, the speed would vary too. I understand spread spectrum in...

In a Van de graff generator, the positive conductor which is connected to the power supply (of high voltage) generates an electric field of high value, which results in dielectric breakdown of air and the positive charge gets "transferred" to the insulated belt. The book says " positive charge...

I am trying to design a tone generator similar to those used in telecommunications applications (ex: http://www.tessco.com/products/displayProductInfo.do?sku=89724&eventPage=1) The probe (inductive amplifier) can be used on any tone generator, so I plan to use it with mine. So far, I have...

Hi all, Sorry if this is an incorrect part of the forum. Living a relatively sedentary lifestyle, consuming a Western diet, living in an area where drivers see pedestrians/cyclists as moving targets to run over and after packing on a few pounds, it got me thinking. I'd like to (as a...
