In 1928, Paul Dirac introduced an equation that combined quantum mechanics with Einstein's relativity to describe the electron. By expressing the electron's wave-like behavior and its relativistic energy the equation led to the prediction of particles identical to electrons but with positive charge. These "positrons" were later observed experimentally in 1932 by Carl Anderson - confirming the existence of antimatter.
Heartbreaking to watch. Western media can watch Pezeshkian at the UN and call him “reformist.” But this is what reform looks like in Iran: little girls forced into hijab at age 7 just to go to school.
It’s The Handmaid’s Tale in real life. It’s gender apartheid. A regime that denies a child education unless she covers her hair is not reformed, it’s criminal.

Phosphorus inputs are important for crop🌽🌱🌾 yields. In the EU 🇪🇺, we can reduce P inputs by 20% without without adverse impacts on crop production. Important for farmers👨🌾🚜. Get our last study in @sciencedirect . #agriculture#phosphorus https://t.co/J3jFU2AF1T
@RonJ844514@tiagopita Fico contente, gosto de ouvir histórias boas e essencialmente ver as pessoas bem. Eu também sou amiga das pessoas aqui em Portugal e dou-me bem com elas. O problema é mesmo o trabalho em si.
