Why do so many people complain about science being politicized?
Anyone who knows even a little bit about the history of science knows that science has always been highly political.

I have been reading Kepler. Does anyone want to tell me what the FUCK he is talking about with this relation? I cannot figure this shit out.
Astronomia Nova, Johannes Kepler, p.362 (Green Lion Press ed.)
'...And we would then say that as the length of the semicircle is to the sum of all the distances on the semicircle, so is this distance of the arc DG to the length of FD, which is the apparent size of CD seen from B.'
Now, if this strikes you as off, it should because that is a STATIC ratio to a dynamic one, something that necessarily changes.
Now, confusing things even more is what he means by this. Forget the fact that the first ratio is astronomically small (no pun intended), the second ratio is pretty clearly a very large one, as the distance of the overall arc from the Sun, which is what they are referring to, is compared to the overall length of the arc itself, which being 1 degree in the example given, is very small.
If he literally means the lengths of GD compared to FD, this doesn't make sense either, as this is clearly a large ratio, not a small.
Does anyone have any idea what the hell Kepler is referrring to in Chapter 48 of Book 4 of Astronomia Nova?

With all the talk of "the competency crisis" floating around on the Internet I got curious: what causes a society to become incapable of maintaining itself and repeating things it has done in the past?
Are the alarmists just scaremomgering?

Teaching a class and I'm looking for advice regarding the quantitative analysis of phosphorus lab. The assignment in the chem 2 class reacts phosphate with ammonium molybdate, making the yellow solid. Then, they measure absorbance of the yellow solution. So, they're making the yellow solid (which is a qualitative method) and then trying to use absorbance to determine concentration (a quantitative method). The solution they make is slightly yellow, I think because there's excess yellow solid just floating around in it. So, spectroscopy might let you determine "amount of stuff floating around", but "amount of stuff floating around" is not a function of phosphate concentration, so long as there is any phosphate present.
I could be wrong in my thinking that the slightly yellow solution just has excess solid floating around, and there is some additional reaction happening making the solution yellow, or the solubility of the yellow solid is known and can be used to back calculate concentration, for example. However, I cannot find any literature or textbook to support the method their lab manual uses, or anything suggesting one of my alternative counter examples is valid. I think someone confused/blended the two methods and it's just a bad procedure? Or, there is some information I don't have?

Why are right leaning Whites only interested in IQ tests and standardized scores when it shows that they are better than blacks, but will quickly shift the goal post when it shows that Asians (and even East Indians) are smarter than Whites?

If the earth is round how come nobody has proven it?
I will only accept measurements of the earth's geometry as proof.
And you can't use the sky as "proof" of anything because you can only see it from a limited perspective it could be a hologram for all we know.
Also NASA data should be omitted as they are known fraudsters

ποΈ π§΅ Biggest error of humans
Speedrun Enlightenment at Tue, 5 Nov 2024 15:16:18 UTC No. 16463612
Let me present you biggest perspective/perception error of humans (I know of so far).
We have our concepts of 0 and infinity swapped.
1-1=infinity
1/infinity = undefined
Numbers were developed over time we added 0 and infinity as concepts later, we may just have them swapped from get -go. (That poor bastards didn't have a clue how we use those 1000s years later)
I can find only this so far

𧡠universal vs sex-dependent brain circuitry in predicting partner preference
Anonymous at Tue, 5 Nov 2024 11:38:34 UTC No. 16463429
Would your sister be able to predict your (a male) preference in girls better than other acquaintances? (or vice versa)
Basically, because you are genetically similar with your siblings, you should have similar brain circuits. My theory is that even though male and female sexuality are different, it would still likely overlap with other general brain circuits, so your relative of an opposite sex might be able to somehow "get" your preference better than a random person, even if they don't feel that way personally.
To test this, the male test subject should bring his sister and a female acquaintance for control. The test subject will be given pairs of images of girls and asked to pick whichever is most attractive, and the control and sister, should pick whichever they think the test subject prefers. Then you could compare results between the control and the sister to see if the genetic similarity gives her an advantage in predicting the subject's preference.
To better isolate the effect of genetics, you might want to use a sibling or close relative that were separated at birth, and a non-acquaintance participant for control, though the event of having been separated might also confound the results. Not sure what's the best methodology.
With classified test images, you could also test what kind of variables (like body proportions, skin color, facial features) your sister can predict better, indicating it's part of an universal thought process associated with your genetics, and see which preferences can't be predicted with opposite sex brain circuitry. It could even be that your sister would be worse than control at predicting some preferences, indicating that the opposite sex would directly invert the output of some brain circuits.

YouTube really be deleting my history. I remember there was a 2-3 hour long oncology lecture with a 4chan jew first explaining how cancer works for like 2.5 hours and then in the last 30 minutes shilled a machine that elevated your body temperature for the sake of fighting cancer.
Can anyone link that video? It's the best cancer tech breakdown I've ever seen, and now I can't find it.
