The phrase "no two snowflakes are exactly alike" sparks wonder in the hearts of children everywhere — but what does science say about this oft-repeated truism? In short, that scale matters when making ...

Our intuition tells us that it should be impossible to see whether two identical objects have been swapped back and forth, and for all particles observed to date, that has been the case. Until now.

Our brains create false perceptions through these illusions, which make us see things that do not exist while they distort ...

Of all features of the quantum realm, the forms that particles take are surely among the most bizarre. There are only two possibilities: identical objects that can mash together (bosons), and ...

Quantum particles are known to be strange or even “spooky.” But can those properties ever be useful? A new study proves that one type of wackiness—entanglement between identical particles—has ...
