Os mais importantes avanços da Física em 2005

por Andre

De acordo com o American Institute of Physics (AIP) a mais importante notícia do ano em Física foi o relatório conjunto dos quatro detectores do RHIC afirmando que o novo estado criado com a colisão de íons pesados não era um plasma (fracamente interagente) de quarks e glúons, como se dava como certo por vários anos, mas sim um líquido fortemente interagente dessas partículas.
