Dnes sme diskutovali o tomto probléme a pokúsil som sa načrtnúť simulačné riešenie:

Prečo je vektorový súčin vektorov násobený sínusom uhla a nie kosínusom uhla:
ono, je jasné teraz prečo musia byť úchyty na stenu kolmo 90 stupňov, lebo vektorový súčin vektorov axb=absin(a) teda krát jedna - teda ak máte úchyt nie kolmo na stenu, tak ani uhol nebude čisto 90, [...] Read more
Can you imagine this ratio in your head?
2 important angles 45 and 2*45 so dy=0-sqrt(2)/2 dx=pi/2-pi/4=pi/4 ; ratio then 0-sqrt(2)/2 : pi/4 == 0.900 😃 ^^^ wanna paint my imagination on the circle sin cos angles?? 😛 ^^^ [...] Read more
How do I see Einstein’s Temp equation of black holes? I’ll paint in red. Now what is the intersection of these planes? Yes, octahedron:
All right guys I saw a small equation from Albert and I had for longer time in my head this idea of the third root of a value which is just diagonal of cube object. What i’ve noticed in Albert’s eqn [...] Read more
When I saw this picture, it was love at first sight: Yes, we can clearly point at Maxwell equations drilling time space in spirals by the speed of light

Skúsite si predstaviť hádanku z hlavy? Obrázok, o ktorom dnes diskutujeme:
Dnes diskutujeme ako vidíme oblasť R: Já takto nejako len z hlavy v mysli: y>abs(-x) && y<x+8 && y€<0,8> [...] Read more
Prečo aj toto pole neudelí bozónom/časticiam hmotnosť? Študentská naivná predstavička o Coulumbovi:
zaujímavé, čo keby bola častica v kolumbovi len 1: ma=kq1q2/r^2 ako získa hmotnosť? no jedna bude poľom Q=CU, teda: ma=kq1CU/r^2 Sme team, sme fyzici ;) toto je moja naivná predstava zo strednej [...] Read more
Story: Today I’m cooperating with NASA, my proposal is DMS
Today I was invited to NASA Johnson space center to see what is going on the space station. As I saw their fetus in space I had immediately in mind this fetus is deformed by bubbles of water. To fix [...] Read more
I was discussing simple equation solution and finally found similar picture on the web
I did not know this might be photon movement related ^^^ . This was my imagination: In simple words, author says: When continuous function equals discrete one: [...] Read more
Story: Can neutron star huge gravity slow down light speed by whirling?
We are discussing now, there is no concept of mass in singularity as m=E:c^2 , but I am objecting what is meant to be this mass m: it is ratio of Force and gravity constant m=G/g Then I think if the [...] Read more
