Interesting: r^3-z^3=x^2+y^2=x+y+z where x^2+y^2=x+y+1; x(x-1)=y(1-y)+1 where -x/y=(1-y)/(x-1)+2x/x-y/y and (y-x)/y=(1-y)/(x-1)+2 and (y-x)/y-1=(y-1)/(1-x)+1 proving [x,y]=[1,1] for -1==1 and which [...] Read more

Keď som videl tento obrázok od fyzikov a ich otázku: Čo prúdi dovnútra sústavy, ak vesmír expanduje? Napadlo ma jednoduché riešenie: Vesmír okrem toho ešte rotuje okolo zvislej osi. Čo sa vtedy [...] Read more

Tento problém je v matematike popisovaný ako problém ťahu. Majme teda tri zakryté kartičky a pod nimi dve kozy a auto. Ako by sme teda dokázali, že ak vytiahnem kozu, oplatí sa ešte ťahať znova, aby [...] Read more

What is wrong on this picture? You can think as long as you want to :) Look at this image. There are two pictures. What is wrong with those two pictures? Saying 'everything' isn't an answer. I'm only [...] Read more

well nice but why not to say immediately 1-cos^2-cos^4 is 1-cos^2(1-cos^2) which is 1-sin^2cos^2 and *4 is 4-sin^2(2a); 2a max can be only 1^2 for 2x45 and (b) 3<=A<=4 is the solution ;) coz [...] Read more

Last time I was reading some pysicists and astro physicists discussing the human body origin and life in universe. We were discussing whether humans are dimension less and I again had a point towards [...] Read more

Hey guys, I'm here with my new story. I'm reading NASA engineer nick named "Sonny" and he claims if we have warp, we need a different shape of the ring. But why is that? And can we prove it by math? [...] Read more
