Molten metal solidifies into a new kind of glass

(Âé¶¹ÒùÔº) —When a molten material cools quickly, parts of it may have enough time to grow into orderly crystals. But if the cooling rate is too fast for the entire melt to crystallize, the remaining material ends up in ...

Time's quantum arrow has a preferred direction: BaBar experiment confirms time asymmetry

(Âé¶¹ÒùÔº)—Time marches relentlessly forward for you and me; watch a movie in reverse, and you'll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the ...
