however, there is a dark history of forced labor associated with cotton. The white cotton in southern US was once soaked with the blood and tears of black slaves – it’s a sin that the US can never wipe off.
In 2002, Remington Arms began developing a new cartridge in cooperation with United States Special Operations Command (SOCOM) and the U.S. Army Marksmanship Unit. The 5th Special Forces Group was seeking an alternative to the 5.56×45mm NATO for use in short-barreled combat rifles. The 5.56mm...
So this is all fine and dandy, but what evidence do we have for this quantum vacuum occurring? Observations of a pulsar's rays using the VLT telescope in Chile showed evidence of a vacuum birefringence. This is an interesting feature of optics in which light passes through a special material...
Physics-Informed Neural Networks (PINN) are neural networks (NNs) that encode model equations, like Partial Differential Equations (PDE), as a component of
Modulation is usually applied to electromagnetic signals: radio waves, lasers/optics and computer networks. Modulation can even be applied to a direct current -- which can be treated as a degenerate carrier wave with a fixed amplitude and frequency of 0 Hz -- mainly by turning it on and off...
When first introduced for commercial use, the optical disk could hold much more data than similarly sizedmagnetic storagemedia, but improvements in hard disk drive (HDD) technology led to HDDs with much greater capacities on a per-centimeter basis than could be achieved with optical disks. At th...
Physics. This exam typically includes questions on optics and wave phenomena; thermodynamics and statistical mechanics; classical mechanics; electromagnetism; quantum mechanics; atomic physics; special relativity and laboratory methods. It also includes questions on specialized physics topics such as nuclear ...
concepts, rather than just beinghumanly interpretablein terms of these. When I turn to concrete study cases below, I will put especially the second one to work. However, I clearly do not claim to definitively settle the matter here. All I am urging iscautionwith concept-attribution to AI ...
The beginning of the week brings on the Pegasid meteors and we can all use a “warm up”! There’s plenty of things to do, so whenever you’re ready, just meet me in the back yard. Monday, November 12 –Wouldn’t we all have loved to have been there in 1949 when the first ...
(optics) Can mean any of radiant intensity, luminous intensity or irradiance. Strength The capacity to resist strain or stress; durability The strength of the cables. Intensity (astronomy) radiance. Strength The ability to deal with difficult situations or to maintain a moral or intellectual positio...
