eh?

who's chladni? waveplates sound interesting...more input.

--> are you looking for a program that will simply sum the variousfrequencies> you give it and display the resulting interference pattern? If so, then> that'd be fairly easy to code. :)  Trust me, I have limited knowledge of COBOL and C.  The most advancedthings I did in C were pointers and some arrays!

What I wanted it to do was to take a set of frequency such as those takenfrom a radio telescope pointing at a certain object, take those and findwhat the resulting pattern would be, just as if it were placed on asandtable (waveplate???).

Unfortunately, not being a scientist in the field of radio telescopes, Ihave no idea what the information looks like when received from space. Imight have to do some reading when I have time.

Oh yea, I just heard that duck "quack's" are the only sounds that don'techo. Can anyone enlighten me this?
