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. If I hear another trivia science factoid from an ignorant eager dumbass top scoring student I will access all printers in the instotute from a library computer and make them print full pages of fine print rainbow NIGGER NIGGER NIGGER NIGGER till they all run out ink.

🧵 What are some (not entirely sci-fiish) paths to more efficient rocket fuel are there?
Anonymous at Sun, 9 Jun 2024 23:08:21 UTC No. 16225720
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?

How much are we influenced by our gut bacteria ("I want to eat X.. I need to drink Y"), it seems we are ruled by it but it can be changed over time, tastes evolve through our years and habits..
Am I the megabiome or just a slave to the microbiome?

Why can't nonimaging concentrating optics be used to make a perpetual motion machine of the second kind?
>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.

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

renewed, more accurate genetic map now show how human and bird gene are quite ditinct from jellyfish and insect happens to be closer to jellyfish
eventhough insects evolved from land crustaceans 330 million years ago, they must have split of from jellyfish later than human did because human genes (actually fish genes) went so far away
fish separated from the jellyfish maybe 700 million years ago already
but for 300 million years fish were very simple
for a while, it looked like lobters may be the most advanced life form on Earth but somehow fish managed to get more complex than a lobster, finally developing more complex brain than lobsters own brain

What are the odds of experiencing 12 consecutive monthly record highs when you look at the past 84 years?
I suppose if you only look at one year, it's 100%. If you look at an infinite number of years it's 0%. How do I calculate this for 84 years?
