A mecânica de Galileu

A Queda Livre – Galileu Descreve o Movimento
Abordaremos o desenvolvimento de um importante exemplo de investigação básica: o estudo dos corpos em queda livre feito por Galileu Galilei. Embora o problema físico da queda livre seja por si só interessante, o estudo será orientado para a maneira como Galileu, um dos primeiros cientistas modernos, apresentou os seus argumentos. A sua perspetiva do mundo, a sua maneira de pensar, o seu uso da matemática e a sua confiança nos testes experimentais, marcam o estilo da ciência moderna. É por isto que estes aspetos do seu trabalho são tão importantes para nós como os resultados reais da sua investigação.

Einstein’s Quantum Riddle

Join scientists as they grab light from across the universe to prove quantum entanglement is real

Over the past century, scientists have made huge strides in understanding the mind-bending rules that govern the microworld of atoms and subatomic particles. But these rules, called quantum mechanics, contain one particularly bizarre, unexplained phenomenon: quantum entanglement.

Imagine two subatomic particles that mirror changes in each other instantaneously …
