Cold atoms could also potentially measure much lower vacuum pressures than ion gauges can. The current lowest pressure they’ve reliably measured is around 10 -9 Pa, and NIST scientists are working on ...

Ok, as I understand it we have no way to determine the speed which we are moving at in an absolute sense.<BR><BR>We can say "We are moving 20 miles per hour in the car relative to the road" or "The ...

This force will cause the cart to accelerate—in this case, to the left, or the opposite way it was heading, which is why it slows down during impact and even reverses direction. But what is the ...

This research suggests that even chaotic, unpredictable phenomena, like waves on a shore or the beating of a heart, can be ...
