    Well, I was kind of hoping someone would raise an objection to using a radio receiver like this. Determining the total background...

    radio volume will be the internal control of amplifier right? how does it being maintained constant at various frequencies/power, convey the strength...

    Can you think of a way to use a multimeter as a signal meter that measures field strength? If you attach an...

    Mass is conserved. An electron has, like all massive particles, a rest mass. But electrons can only truly be at rest at...

    Measuring an electric field

    Riddle me this: If you have a battery-powered radio, can you think of a way to use it to get a qualitative...

    I assume you mean a waveform generator? A piece of equipment that has sine, sawtooth, square, etc waveforms at various amplitudes and...

    Hypercubic computers

    You may have heard of the Connection Machine. This was/is a massively parallel system in which the processors communicate with each other...

    Compressing files is about redundant codes. What counts as redundant depends on the file. Check out what MPEG and JPEG compression is...

    Okey dokey. I think I've managed to finally see the connection between the puzzles (starting with the Pocket Cube) and Riemann space...

    One other detail I think is important: the figure I keep mentioning which you can form with an algorithm: "X,Y',Z',X", as long...

    Hmm. I would say that the movie used a "toy model" of quantum physics.... Put it this way, if you see a...

    Ok, another clue for mathematicians. If you imagine the numbers are piles or stacks of Rubik's cubes, each looks different, but some...

    A Fibonacci series (recurrence) is: a[sub]n[/sub] = a[sub]n-1[/sub] + a[sub]n-2[/sub], with a[sub]1[/sub]= a[sub]2[/sub] = 1. So a[sub]3[/sub]= 1 + 1, a[sub]4[...
