2:25 PM | In breve: la cascata dei barioni
In maniera semplice si può parlare di meccanica quantistica nel momento in cui si descrivono le proprietà delle particelle utilizzando i numeri interi. Fatti quei primi passi all'inizio del XX secolo, come fisici abbiamo descritto le particelle utilizzando i così detti numeri quantici in grande abbondanza: la loro scoperta era sempre legata alla scoperta di nuovi decadimenti che non potevano essere altrimenti spiegati senza violare la conservazione di un qualche numero […]

9:51 AM | How guessing the wrong answer helps you learn the right answer
Guessing, even wrongly, is thought toactivate webs of knowledge, which leadsto richer encoding of the correct answer. It's well known that taking tests helps us learn. The act of retrieving information from memory helps that information stick. This seems intuitive. More surprising is the recent discovery that guessing aids subsequent learning of the correct answer, even if your initial guess was wrong.Let's consider a simple example in the context of learning capital cities. Imagine you […]
