should've become a carpenter, rather than spend years in this environment of sensationalist claims and overly complicated descriptions of simple and boring systems; saturated with pompous basedientists gaping their mouths at consequences and facets of everyday work that are fundamentally trivial.

I share your sentiment, however you should remember that any pompous retard can make things bigger and more complex but it always takes a genius to move in the opposite direction.
The years you've spent studying will pay off once you realize that humanity walks in the opposite direction by decreasing the number of significant scientific discoveries (ask your nearest NPC about any creative endeavor at all and they'll advocate for doing nothing because "everything's already invented" even though we live in a Kafkaesque nightmare in regards to scientific advancements).
Discerning shills from actual facts is easy when you actually apply the "fuck around and find out" method of actually arriving at perennial truths and that in the end science will always be different from Science.

I bet we can agree that fuel is the most annoying part of even the most advanced of the modern space vehicles.
You blow the fuel up controllably making a huge mess, but worst of all, the ratio of fuel per kilo lifted is so bad, that the whole thing is not just inelegant, but stupidly expensive.
Is there hope?

Are you overweight? Be honest.

Also, how much do you scrub yourself? Consider getting s brush and give yourself a rough scrub all over.

Lastly, it's not uncommon to smell a little after a shower in my experience. Like if you press your nose into your armpit and sniff you can still detect a faint sweat smell

>what are nonimaging concentrating optics?
Dunno really, supposedly it's meant to allow you to get past the problem of Etendue, which might stops you concentrating light to a brightness above the source. This obviously cant be otherwise we break entropy.
This is a paper using a NICO to increase the brightness of sunlight to pump a laser. The brightness achieved does not exceed the surface of the sun but gets close.

Here's a perpetual motion machine of the second kind using a NICO to concentrate emissions of a large, cold black body (BB) radiator to a hotter, smaller BB, allowing them to be in thermal equilibrium in a paradox.

If you could "somehow" make a NICO with a sufficient concentrating factor (concentrating the emissions from one area to that of another 16 times less), this would work.

Here is a much simpler paradox which allows two BBs to have their photon emissions in equilibrium, yet their temperatures be different.

The solution to this paradox is solved by making the BBs a finite size, as then the foci of the circle and ellipse no longer match correctly.
Good paper explaining it. Gives pretty pictures for a QRD.

RETRACTED: Drought sensitivity in mesic forests heightens their vulnerability to climate change
https://www.science.org/doi/10.1126/science.adi1071

The authors of a paper published in Science have retracted their article following the discovery of calculation errors.

The article,“Drought sensitivity in mesic forests heightens their vulnerability to climate change” by Robert Heilmayr of the University of California, Santa Barbara and colleagues found that in drier areas, trees are less sensitive to drought and in hotter regions with a wet climate, tree growth is expected to decrease.

It has been cited once, according to Clarivate’s Web of Science. Since its publication in December, the article has been downloaded 4,641 times, posted by 154 X users, and written about by 20 news outlets and press release sites.

In January, a group led by Stefan Klesse of the Swiss Federal Institute for Forest, Snow and Landscape Research informed the authors of errors in their R script, which was used to characterize weather and climate in these drought-affected regions. When the authors reran their script, the statistical significance of some conclusions, and test results changed – prompting them to retract the work.

“We believe the journal has handled this process incredibly well,” Heilmayr told Retraction Watch. “They encouraged us to work with Klesse et al. to get to the bottom of their concerns, and then followed our recommendation to retract the paper. Although we are disappointed, we were happy we were able to correct the scientific record.”

Klesse and his colleagues did not respond to our request for comment.

Four papers have been retracted from Science since the beginning of last year. The first was a similar case, in which researchers discovered an error and the authors retracted. Two involved the high-profile case of former Stanford president Marc Tessier-Lavigne, and the other was from another high-profile case at the Dana Farber Cancer Institute.

A spokesperson for Science said “It continues to encourage us to see examples like this where a data user lets the authors know about an error and the authors work quickly to correct the record.”
