“The forces which [Newton] introduced left Nature still without meaning or value. In the essence of a material body—in its mass, motion, and shape—there was no reason for the law of gravitation. Even if the particular forces could be conceived as the accidents of a cosmic epoch, there was no reason in the Newtonian concepts of mass and motion why material bodies should be connected by any stress between them. Yet the notion of stresses, as essential connections between bodies, was a fundamental factor in the Newtonian concept of nature. What Newton left for empirical investigation was the determination of the particular stresses now existing. In this determination he made a magnificent beginning by isolating the stresses indicated by his law of gravitation. But he left no hint, why in the nature of things there should be any stresses at all. The arbitrary motions of the bodies were thus explained by the arbitrary stresses between material bodies, conjoined with their spatiality, their mass, and their initial states of motion. By introducing stresses—in particular the law of gravitation—instead of the welter of detailed transformations of motion, he greatly increased the systematic aspect of nature. But he left all the factors of the system—more particularly, mass and stress—in the position of detached facts devoid of any reason for their compresence. He thus illustrated a great philosophic truth, that a dead nature can give no reasons. All ultimate reasons are in terms of aim at value. A dead nature aims at nothing. It is the essence of life that it exists for its own sake, as the intrinsic reaping of value.”

Hi everyone, recently I have many tests, so I just want to make a post on some tips I find helpful and effective for me while reviewing for tests. These tips might only work for me, so take them with a grain of salt! Feel free to try out if you want to!
Happy Lunar New Year also to those who celebrate it! 🧨🧧
QOTD: How do you usually prepare for a test/exam?
i read atomic habits so you dont have to lol

Radio Astronomy
So I learnt something really cool today. Radio astronomy. Radio astronomy is done at ~ 1.4 GHz frequency. WHY YOU ASK??? Because hydrogen is the most abundant element in the universe!!! And hydrogen atoms have one electron !! Electrons possess spins!! Spins can flip!! And when they do, they emit a wavelength of 21 cm!! Which corresponds to a frequency of 1.4 GHz (f = c/λ). And since hydrogen is basically EVERYWHERE, they use that to observe celestial bodies and it is a very protected frequency which means radio stations, satellites and cellphone towers can't use it!!
Spectrum of spectroscopy
Life is colorful in the Kolemen lab at Koç University. The group is investigating a wide range of small molecules as fluorescent probes for biological imaging and as photosensitizers for light-driven cancer therapies. Here, a member of the lab took a moment to savor the sight of a set of cyanine and xanthene derivatives, part of the phototherapy work, loaded into NMR tubes. — Craig Bettenhausen

Smoking marijuana may harm a man's fertility, according to new research. But men who smoke pot may also have sperm that are faster swimmers.
Researchers found a connection between low semen volume and damaged sperm among men who smoked marijuana. But the side effects weren’t all bad. The study also found that men who smoked marijuana were more likely to have sperm that swam faster.
“This is one of the first studies that show a decline in sperm quality in current and past marijuana smokers, compared to non-smokers,” says Omer A. Raheem, assistant professor of urology at Tulane University School of Medicine and lead author of the study in the journal Therapeutic Advances in Urology.
“This is significant because it adds to the evolving evidence of the potential negative impacts of marijuana on human reproduction.”
Globally, marijuana use has risen by 60% over the past decade, and the drug affects more than the mind. Cannabis has compounds that can affect the male reproductive system, yet prior studies haven’t agreed on how that affects fertility.

I think everyone’s mathematical journey would have been so much easier if they showed you the sine, cosine, and tangent unit circle (R=1) animation in precalc
Below is sine and cosine graph in relation to circle (R undefined)
Below is tangent graph in relation to circle (R=1)
below is all six trigonometric functions on unit circle (R=1)

“Progress in the field of nanotechnology means that these robotic systems can be scaled-down to a microscopic level. Nano-scale robots could be especially valuable in the medical field, as intelligent surgeons that operate within the body on a molecular level — making it appear as if cancers in sensitive areas full of nerves, which a scalpel runs the risk of severing, are simply dissolving. Unclogging arteries would also be a lot easier. But the implications of these nanobots for industry are truly astounding. Imagine the 3-D printing technology of today being replaced by printers that assemble computer-generated or 3-D scanned and modeled objects on a molecular level, akin to the food replicators of ‘Star Trek.’”

how to deal with mental fatigue
Hi, it’s werelivingarts! Exam season is coming so soon, and some of us might deal with a lot of stress and mental fatigue while preparing for the exams.
Here are some tips on how to prevent and deal with mental fatigue (before it becomes too serious and leads to burnout. Exams are just ways to test your knowledge and understanding, so please do not expect too high and take care of your health! 🌿
Hope that we would all do well! 😊

Percentage Purity let’s get it xx
“Thus, the cities of the future, rather than being made out of glass and steel as envisioned by earlier generations of urbanists, are instead largely constructed out of crude brick, straw, recycled plastic, cement blocks, and scrap wood. Instead of cities of light soaring toward heaven, much of the twenty-first-century urban world squats in squalor, surrounded by pollution, excrement, and decay.”
