Olá galero, resolvi começar a fazer alguns posts em inglês simplesmente com o intuito de praticá-lo, estou precisando. E é uma boa desculpa para falar de assuntos não ~polêmicos~ e reviver de vez[?] o blog.
Fiquem a vontade para corrigir qualquer tipo de erro, eu até GOSTARIA que vocês o fizessem, afinal meu objetivo é melhorar meu inglês e não ser um blogueiro de sucesso.
Please correct any english mistake, I’d really appreciate! I’m here just to learn and improve my second language. Thanks!
Too fast and too furious
Recently we had in all kinds of media, papers, tv, internet (etc), the notice that a Neutrino was, maybe, faster than the light speed. As a student of mathematical physics, the idea of a particle running at this speed and, consequently, going against the Relativity, is at the same time which is awesome and scary! If this is true, this probably will be the discovery of the century.
Neutrinos are sub-atomic particles, like electron or neutron, but they have no charge and don’t react mostly with other materials. In the European Organization for Nuclear Research (CERN, French: Organisation Européenne pour la Recherche Nucléaire), researchers sent neutrinos to Gran Sasso, Italy – 732 kilometers – and they were detected in a apparatus called Oscillation Project with Emulsion-tRackin Apparatus (OPERA). The neutrinos ‘‘arrived’’ there 60 nano seconds (1 nano second = 0,000000001 s) before the light, fact that goes against the Einstein’s Relativity. One of it postulates say the light-speed (299 792 458 m/s) cannot be exceed, so if this is true the theory must be adapted.
It’s very exciting to witness a big discovery like that and to follow the scientific environment trying to solve this new problem. And this is also scary, because the Theory may be totally wrong and a good part of the Modern Physics, that depends of this, may be wrong too! Considering the neutrinos really can go faster than light, probably the theory is not fully wrong, just incomplete, because it explains perfectly a lot of facts, like the Newtonian Mechanics do. The Newton’s laws are true only when the velocities aren’t big (in other words, when they aren’t close to lightspeed) and when the objects aren’t as small as a atom. So the theory was expanded to Relativity and Quantum Mechanichs, respectivelly.
At the moment we just can sit and wait the new reproductions of this experience with neutrinos and follow the news! In my opinion this experience has some mistake, because it is not the first time that a group of scientists say they discovered that a particle can be faster than light and all the previous times they were wrong. On the other hand, I think that is possible exceed this velocity, but it’s just a guess not grounded.
lol
This is an video of a brazilian physics student called Tomishyio, but it is in portuguese. It’s very interesting:
Bye, folks!
