/sci/ - Science & Math

I only know calc I-III and some linear algebra.

The MIT Challenge was started by Scott Young where essentially you do four years of CS courses in one year.

Literally nothing interesting has happened in science since quantum theory.

What's the proof that atoms even exist?

Are any of you even over 22 years old?

I had a dream last night. I walked up to a difficult integral and demanded it "bend over and show me [its] derivative"
I woke up rock hard.

Is it medically possible to cut persons head and keep it alive with artificial blood and other liquids circulation for a long period? Like one week fir example?

I mean I know that soviets in 50s or 60s did such experiments with dog heads but they were alive just for few seconds

Could we now keep them longer? Wouldn't it be cool?

why is everything in fluids non dimensionalized? what does that even do?

>David Swenson of 3M Corporation describes an anomaly where workers encountered a strange "invisible wall" in the area under a fast-moving sheet of electrically charged polypropelene film in a factory. This "invisible wall" was strong enough to prevent humans from passing through. A person near this "wall" was unable to turn, and so had to walk backwards to retreat from it.
>This occurred in late summer in South Carolina, August 1980, in extremely high humidity. Polypropelene (PP) film on 50K ft. rolls 20ft wide was being slit and transferred to multiple smaller spools. The film was taken off the main roll at high speed, flowed upwards 20ft to overhead rollers, passed horizontally 20ft and then downwards to the slitting device, where it was spooled onto shorter rolls. The whole operation formed a cubical shaped tent, with two walls and a ceiling approximately 20ft square. The spools ran at 1000ft/min, or about 10MPH. The PP film had been manufactured with dissimilar surface structure on opposing faces. Contact electrification can occur even in similar materials if the surface textures or micro-structures are significantly different. The generation of a large imbalance of electrical surface-charge during unspooling was therefore not unexpected, and is a common problem in this industry. "Static cling" in the megavolt range!
>On entering the factory floor and far from the equipment, Mr. Swenson's 200KV/ft handheld electrometer was found to slam to full scale. When he attempted to walk through the corridor formed by the moving film, he was stopped about half way through by an "invisible wall." He could lean all his weight forward but was unable to pass. He observed a fly get pulled into the charged, moving plastic, and speculates that the e-fields might have been strong enough to suck in birds!

>finish lecture
>never see her again
I guess it's not really funny, just awkward as hell.

Why is appeal to authority in science so vastly used? Scientific consensus is considered proof when there's not supposed to be any authority in science.

You're the POS who made the uni thread and pretended to be from UCLA aren't you?

In the land of 0 IQ, the man with 1 IQ is king.

Honestly I welcome skepticism towards harmful chemicals in vaccines. Most academics are practically religious in how strongly they believe in vaccination and hate "anti vaxxers" and just put labels on people so they can shut them out. I think you should also keep in mind that the same people who are mindlessly "pro-vaccine" are the people who also spent three months kvetching about racism towards Chinese while the virus spread to America and called Trump racist for grounding flights and suddenly changed their tune when it actually became a problem.

I'm not anti-vax myself, but science isn't something that you should "believe" in because it's not a fucking religion. Obviously conspiritards are probably more religious than leftists, but there's a reason conspiritards keep getting pushed farther and farther into idiocy, and it's not really because of their own idiocy.

Chinks put way more money and effort into pushing pro immigration and anti racism garbage in the west. I've had chinese professors that spend entire semesters talking about how evil white people are.

In short: I fucking hate the Chinese, I hate leftists, and the right has it's heart in the right place but they're fucking idiots who don't deserve power. Overall, I'm concerned about this country, but saying "my side good, your side PRC shill" is a gross oversimplification.

How do people without inner monologues self-reflect or think about abstract ideas?

If you were struck by a high energy cosmic ray like the oh-my-god-particle, would you feel it? Would it hurt?

very profound discovery I see

what is meant by a "cure for cancer" and why doesn't cutting it out/chemo count?

Because retards will believe anything based on party lines and what faggot news agency they listen to. Modern man willingly indoctrinates himself with hour-long propaganda cable shows and podcasts and SPENDS THE WHOLE DAY LOOKING FORWARD TO IT. Personally I think it's a replacement for the natural senses of racial, cultural and religious identity we've lost or repudiated, for better and for worse.
