Za one koje zanimaju temelji fizike evo jednog elementarnog uvoda u Einsteinovu specijalnu teoriju relativnosti:

Pdf-ovi (koje koristim u gornjem predavanju) mogu se bolje vidjeti ovdje:

pa si ih možete iskopirati i uz njih lakše pratiti izlaganje.

Inače, predavanje sam održao na:

The Fourth PHYSICS & PHILOSOPHY Conference “Time, Space and Space-Time” :: University of Split – Croatia :: 6–7 July 2015.

pod naslovom “There is only one speed”.

Abstrakt predavanja:

Minkowski developed the four-dimensional physical space by combining three space coordinates and a time coordinate into a four-dimensional event and hereby: „Space by itself and time by itself are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.“

Einstein joked that he no longer understood the special relativity (since the mathematicians took it up) but it is clear that the new geometric perspective was a great advance.

It enabled Epstein to conclude that everything moves with the speed of light in this four-dimensional space-time: “The reason you can’t go faster than the speed of light is that you can’t go slower. There is only one speed. Everything, including you, is always moving at the speed of light.”

We will explain what lies behind these extraordinary assertions.

    Jako lijepo predavanje, poanta mi je otprije poznata iz nekoliko boljih popsajens naslova.

    Stalno mi se vrzma po glavi misao da su zapravo čestice s nultom masom mirovanja kao što su fotoni (prenositelji EM sile) ili gravitoni (još nepotvrđeni nosioci gravitacijske sile) ili gluoni (jaka sila) pokretači svih zbivanja u svemiru baš stoga jer su NAJBRŽI, jer moraju imati brzinu c. Zažmirit ćemo na bozone:) Kao da su fizikalni zakoni kodirani u te sablasne čestice. Tko je NAJBRŽI taj kolo vodi.
