Hello,

I see in a book that when  we have waves,
there is some rules between "length" of the wave, proper values of a vibrating system, and resonance...
to have "stability" (sorry my english is basic, so i have difficulties to explain "my idea") we need :

for N=1 to infinity
Ny=2L

exemple : y=2L  N=1  one curve between 2 extremum fixed and 1 middle point of resonance...
                y=L   N=2  one curve between 2 extremum fixed and one middle point fixed,  2 points of resonance..
                y=2L/3 N=3 one curve between 2 extremum fixed and 2 point fixed at 1/3 of the lenght,  3 points of resonance..
etc....like sinusoide

i was "puzzled" by the number of resonance points, N and 2L...
there are correlations between Fourrier, music, and spectre of  wave.
(i know that you know, but me  i discovered this  yesterday :o) lol)

so
when i see all this schema i remenber the sequences of :
0,1,0,1,0,1,0,1,0,1,0,1,0,1....
or
0,0,1,0,0,1,0,0,1,0,0,1,0,0,1...

and why not for a sinusoid -1,1,-1,1.....

and for 1 and -1
successives expo values of i=racine(-1)

i was amazed to see that the notion of even or odd number in wave scheme is "mixed"

and i ask me, how even, odd, prime looks in "waves" with 2 fixed extremum

is it the same thing than the compression of 0101010101....+001001001001001001...+etc

see recently with your precious help...

thanks
sorry for this nonmethodical, disorganized email.

Best Regards
Eric
