Brass catcher came to mind as an ad hoc solution till you realize that the catcher relied on Earth gravity to settle the cases in the catcher bag, I leave it to the reader ingenuity to think of some one direction value that allows the cases to be ejected to the bag but prevent the ...

𝜎𝑠σs is an experimentally determined sticking coefficient unique to the reagent s, 𝑍𝑠Zs is the coordination number of the gas s, 𝑚𝑠ms is the atomic mass of the gaseous reagent s, 𝑘𝐵kB is the Boltzmann constant, and T is the absolute temperature of the ambient environ...
"Got to play this nice and easy—no pushing a star till you're sure you got a line on the comet's tail—no fast movin'. MOON OF THREE RINGS We reached the end of the straggling collection of amusement places and found a rather pretentious tent of raw scarlet splashed with eye-torturi...
that it may become possible to set up nuclear chain reactions in a large mass of uranium, by which vast amounts of power and large quantities of new radium-like elements would be generated. Now it appears almost certain that this could be achieved in the immediate future.This new phenomenon...
In fact, standard quantum theory postulates (1) no limit on the mass and split distance of a superposition state and that (2) even a negative measurement can cause the wave packet’s reduction. The latter point is indeed central to the Elitzur–Vaidman interaction-free experiment. In the ...
The atomic frequency standards proposed up till now have already been very useful. However, they have different drawbacks. The main drawback of conventional standards would appear to be the fact that the checks on the acquisition of the central peak of the Ramsey response are unreliable. ...
Till human aggression and greed is cured, newer and deadlier weapons of mass destruction will keep on being created. Nuclear weapons have the capacity to wipe out entire cities in a few seconds. There can be nothing deadlier than an atom bomb strike. Sadly, Hiroshima and Nagasaki bear testimon...
'I have it, Tilli,' I radioed, as I felt the cargo crane latch on to the shipping container. A green light on the console confirmed it. 'It's yours,' replied Tilli, releasing the container from the lighter's cargo arm, clearing the last red light. We were over the night side...
