Hi People
Of course there is mental causation, if you include telepathy. How often have you been thinking about sex, for instance, while not looking at the person you're thinking of, only to surprise a look on their face that tells you they were sharing your thoughts? This is a difficult...
Hi Jinfur008
would you please identify the 'eps' operator/function/constant. And I'll have a peek at it.
Also, where did you get that user name? It's like, outa star wars.
Dear Deicider
I cannot answer the question you have asked because it is meaningless to me. Power is not a force which is exerted between charged bodies.
In physics (and in every science) it is important to know exactly what each other is talking about, so we have definitions for words like...
This poor guy doesn't know anything. He could have used the word energy, or force, or power, or probably a dozen other words and, to him, the statements would mean the same.
I vote that we tell him we need the exact wording of any problem from his course that he wants to bring to us.
I also...
Hi Guys
I have been asked to consider modifying a brand-new kit-form electric guitar. The owner envisages an extra rotary switch providing a selection of capacitors providing tone control options.
My instinct is that this modification may be detrimental to the noise floor of the instrument...
While I have not experimented in this way into the required energy to heat water, I have noticed that the results quoted for the specific heat capacity of water always specify the temperature from which the water is to be raised by (usually) 1 degree.
From what I recall the temperature at start...
A forward fft takes you from time domain to frequency domain, the backward fft takes you the other way.
I wonder whether the 'complex' options require 2 arguments (real, imaginary) in each channel of signal? Though I'm rather sticking my neck out here I'd say you have only the option of 'real'...
What level of 'code' do you want to see? I could direct you to the example files for FFT on 'Scilab', which you could download and install in half an hour. The example routine first makes a signal out of trig functions, then analyses it using the FFT. You'd see how the syntax of the application...
There is a really good demonstration of the way Fourier series work at this link:
http://www.falstad.com/fourier/
The link provides a Java applet which allows the viewer to play with the amplitudes of the sin and cos harmonics so they can see what is going on.
The freeware Matlab clone, Scilab, is wonderful at showing all the harmonics but takes a lot more effort to get working than Audacity (I used scilab to determine the fundamental resonant frequency of the body of my guitar).
