The path toward realizing practical quantum technologies begins with understanding the fundamental physics that govern quantum behavior—and how those phenomena can be harnessed in real materials.

And that is absolutely 100% accurate, with no measurement errors. But Jack, I hear you say, what are you talking about? The reason we know that that's exactly the speed of light, is that we defined it ...

A peak flow meter is a user-friendly, portable device that helps measure the ability of the lungs to expel air. It estimates peak expiratory flow rate which is a measure of how rapidly air can be ...
