CRIMINOSO | Deputado bolsonarista Bibo Nunes (PL) defendeu que estudantes da Federal de Santa Maria mereciam ser "queimados vivos". Santa Maria foi a cidade onde 242 pessoas morreram no incêndio da Boate Kiss.
O 'crime' desses jovens: protestarem contra os cortes na Educação

Paul Dirac and Werner Heisenberg in the 1930s ✍️
Dirac and Heisenberg were two of the pioneers of quantum mechanics, who had different views on the relation between classical and quantum physics. Dirac believed that both classical and quantum theories were open to future revision, and that classical mechanics should be modified to be compatible with quantum principles. Heisenberg, on the other hand, thought that classical and quantum theories were closed and consistent within their domains, and that there was no need to change classical mechanics.
They also had different approaches to scientific methodology and theory change. Dirac favored a mathematical and axiomatic style, while Heisenberg preferred a physical and intuitive style. Despite their disagreements, they respected each other’s work and were friends throughout their lives.

The model Lagrangian is one of the longest equations in physics because it contains many terms and factors that account for all the possible interactions and symmetries of the Standard Model.
It was transcribed by Thomas Gutierrez who derived it from Martinus Veltman's “Diagrammatica: The Path to Feynman Diagrams.”
Eu e o Thalis recebemos @LulaOficial e @JanjaLula para almoço no Palácio Piratini com ex-governadores gaúchos e nossas equipes. Vamos conversar sobre projetos e soluções para o Rio Grande do Sul e o Brasil. Temos o dever de trabalhar em parceria pela população que vive aqui!
