Number 3 has quite special significance considering it from creation's (not religious but phisical) point of view. But I am quite suprpised that Tesla knew it so long time ago...

Re: Maths.
you do realize that 9x any number, then adding the two digits of the number with always give you 9, right?

9x1 = 9
9x2 = 18 = 1+8 = 9
9x3 = 27 = 2+7 = 9
9x4 = 36 = 3+6 = 9
9x5 = 45 = 4+5 = 9

and so on.

you'll also notice that when multiplying a number by 9, say 7 for example, you drop the number by 1 (6) and then just add whatever digit at the end that makes that number (6) equal 9 (63).

these are all simple tricks used to help mental math work faster.

did you not learn this while learning your multiplication tables?

Re: Maths.
Funny also how Tesla says you would have A KEY to the universe, not THE KEY.

Re: Maths.
Thank you so very much, American.

I think this thread can die now.
