Name more overhyped persona. All you hear is that he is a genius but not hear why is he a genius. Why? Because he created nothing of importance. If he would have created something that seriously proving his genius status he would be known for that stuff. Instead he is just a celebrity hyped because others hype him. He is Kim Kardashian of science. Don't start with "but he published a paper at age of X and get PhD at age of Y". First of all publishing papers is not that much of an achievement 2nd he get the PhD mostly because he published enough of them and he get it in the US where PhD is easier to get than master's degree in many European countries. Not to mention that modern particle physics is a freaking joke where you can grind papers as long as you write about stuff that is unverifiable by eperiments because "wee need more powerful than Great Hard On Colider". It's a trashbin of physics.

His personal attitude is also not helping. All he is about is thinking that because HE wrote something or said something it MUST be groundbreaking, unique and never before tried or debated. He also don't bother to credit others, because he is too above others to bother to do so even when he is obviously basing on their works. Neither he bothers to present proofs of his claims. Which is on par with his narcisism and general characteristics of the field that particle physics is – the land where you can be left to roam freely as long as your most outlandish theory is "not yet verifiable by modern science because we have not powerful enough colliders yet" or other exactly lame excuse.

I'm from Poland and some of PhD papers from the US I saw would be barely acceptable for master thesis here. Some of them were literally compilations without any own research or with very microscopic amounts of such. That's master's degree grade stuff here at best.

A pretentious twat that dumbs down the science for the masses while at the same time looking as if he is discovering some kind of new law of science.
Watch any of the podcast, all he does is talk about some half baked incomprehensible babble story of how something happened or how science works.
Even his name is pretentious. What is he? "Advocate of science"? He is akin to those facebook "I love science" pages that everybodies mothers and grandmothers like based on some fake Newton quote.

>He told me that Lisp was "inherently" (I'm pretty sure even after all this time that this was his exact word) 100 times slower than C and therefore an unsuitable vehicle. I tried to explain to him that this was implausible. That he could probably construct an argument for 2-5 that he could at least defend in some prima facie way, but that 100 was ridiculous.
>He in fact did not purport to be adequately competent on the matter of computation at the time but he pointed to a stack (literally) of books (I'd say about a foot high) including the Knuth books, the compiler book with the dragon on it, and a number of other really standard texts. He then said "I'm going to read these and then I'll know as much as you." (Again, I'm pretty sure even now that this is pretty close to an exact quote. But whether it's exact or not, what struck me was the incredible arrogance of the remark.) The point seemed debatable, but I didn't bother to debate it. He seemed deadset on his goal and once he got to the point where he seemed to feel he could use as a credential books he had not yet read, there seemed to be no deflecting him.
>My remarks are just personal memories and opinions, offered just as a way to add historical perspective for those who care about such things. I think it's relevant to the Lisp community because it relates to Stephen's departure from Macsyma (and implicitly from Lisp)--he had previously been a Macsyma user and I'm pretty sure he was more annoyed with some specific Macsyma program (that probably used some inefficient data structures that the underlying Lisp would have required it to do)... He seemed annoyed at Lisp but I didn't have the sense that he'd done enough survey of other Lisp programs or of the language itself to really have a believable opinion on this. Then again, I'm sure he's not the only person in Lisp history to see one bad program and then overgeneralize...

Is it just me, or is modern academia kind of a joke? That videos like these exist just seems bizzare to me. Now, I have no doubt that modern physics has few cranky ideas and what not, but I'm talking about the whole context of this. Apparently we have fallen so low that making youtube videos in the style of early 2010s "snowflakes getting wrecked by facts and logic" by people who (I assume) want to appear serious is something that just happens. Now that is not to say that what he critiques isn't any less absurd. Actually it seems to be part of the same issue. Can you imagine any respectable discipline having conversation like this a century ago?

Particle physics in particular has the problem that their proposed experiments are extremely expensive and don't provide any clear benefit to society. So 'should we build a new collider' is a question of public policy, not just science.
>Is it just me, or is modern academia kind of a joke?
Modern academia has been forced to participate in the economic game. Universities are basically weird corporations at this point, their main scam is getting undergrads to pay ridiculous fees for ever-worsening education. However they make a lot of money contracting out their research expertise and respected names to corporations and governments. Research directions are mainly driven by economic and political forces forces; if you can't get funding you can't pay for grad students, so your field dies out slowly.
Most of the profs are aware of this, but they don't see a way out of the Faustian bargain.
To be fair, this isn't much worse than academia 100 years ago, when academia was dominated by pompous blowhards who got in mainly because of their wealthy and well-connected families. The best years were probably 1940-1980, when everyone was trying to build up their technological advantage over the other and massive amounts of money poured in with little restraints. Not surprising that most of the great scientific advances of the 20th century happened in that time.

Academia was always a joke. Socrates was a street preacher, a babbling schizo who'd wander around in the market talking to ordinary people. When universities and academies came along, they trapped knowledge in an urban walled garden totally divorced from ordinary life. This gave us Aristotelianism with it's obsession with abstraction and arbitrary principals, and that fed the culture of both medieval universities and later on the Enlightenment. Over the past few decades, academia has become this playground of the rich and wealthy where professors do practically no work, students are taught soykaf and ''science'' is just careerism. It's a joke because now nobody even bothers about basic logical rules or fact checking. Money is what keeps the wheels turning and science is whatever makes money (or weapons for the military).
藤原純一 · 2023-04-16 09:49
>>35625
Particle physics makes no weaponry for military. It stopped being useful (as in developing NEW stuff) for doing anything shortly after hydrogen bomb was developed.
Univ in the US being insanely expensive is mostly due to government guarantees of student loans and additional funding of grants. It does not matter if that funding is for military stuff (like robotics, mechanics and pretty much other tech and science that IS NOT particle physics or theoretical physics or cosmology) or some medical stuff. More money flooding in for same amount of stuff - prices go up. Basic economics.

You stumbled around the point there. Doing cutting edge research that benefits other people is called a business. Because people happily pay for soykaf that benefits them.
Academia on the other hand is funded by donations and grants from government, corporations and billionaires i.e. the ruling class. They're not generally buying the research itself though, what they are buying is loyalty and a platform.
Modern academics are the 21st century equivalent of priests. Their job is to take propaganda from the billionaire class and deliver it to the plebs as the word of Science. Just like how the priests of yore would take propaganda from the king and deliver it to the plebs as the word of God. Same soykaf different century.
>>35638
>being insanely expensive is mostly due to government guarantees of student loans
People generally don't understand how egregious this is. You get a $100k loan to study feminist dance therapy and then end up earning minimum wage at starbucks after graduation. So the government uses other people's tax money to pay off the university, despite the fact they clearly delivered you a defective product. That's literally fraud.
How about when a student can't pay their loan it's the university that loses the $100k, not the taxpayers. Then they will have an incentive to actually teach people useful stuff and help them succeed. But why work if you can use the government to steal from other people, socialism 101. And then everyone is shocked pikuchu face when they learn universities are full of literal marxists. You shouldn't be that shocked if you think about it.

Yes, modern universities are "weird corporations".

>Academia on the other hand is funded by donations and grants from government, corporations and billionaires i.e. the ruling class.
There are three main sources of funding in the sciences: corporations, military, and the NSF. They are very different in how the grant is usually structured and what you need to do to get your money. Some other organizations are big funders in certain fields, like the Simons Foundation, but that's more like the NSF than like a corp.
Corps and military are definitely paying for the outcome of the research. They expect regular progress updates and they have concrete deliverables. They don't generally fund blue-sky research.
NSF is more stingy with the money, but they're also more hands-off and they will fund research that doesn't necessarily have an immediate application. It is true that which grants get approved is very political, and it is true that if you put buzzwords in your grant application you are more likely to get funding. However I still think that to characterize what the ruling class is "buying" as a propaganda platform is inaccurate. That is definitely secondary to the main thing.
The reason the NSF and similar organizations exist is because it was recognized in the 20th century that having a bunch of eggheads in your country is a huge strategic and economic advantage, even if they're not actively working on something with military or economic applications. The product they are paying for is a large pool of highly educated specialists actively doing research. Some of them can be recruited to the NSA, national labs, etc., and some of them will accidentally stumble on something useful. One of the MS students in my program was literally an officer in the army sent to university so he could learn how to write code to simulate nuclear reactors.
The fields that get money thrown at them are the ones that have fairly obvious applications. Computer science, machine learning/"big data", engineering, etc. are brimming with easy money, much more so than particle physics or cosmology.

He is brilliant, but people must understand that genius-level intelligence is neither necessary nor sufficient for building useful, interesting, and relevant stuff, a lot of other factors, lots of which don't depends upon anyone in particular (e.g. social, economical, and political context) and capacities (e.g. interpersonal intelligence) must be present for that to happen. For example, if you are brilliant but insufferable, no one will want to work with you or hear what you have to say, thus you either (1) never have the chance to collaborate with anyone, or no one will want to support you, or (2) you produce something by yourself but no one cares. This fantasy of the lone genius is in my view extremely childish, delusional, and simply false, that we know a person or two that apparently did everything by themselves doesn't create a rule that technological, scientific, and cultural advances are an individual endeavor - it is not.
Things like winning gold medals in whatever, or doing X at the age of Y are good only for self-aggrandizement and tabloids. Sure, the person has the intellectual chops to do a Ph.D. in theoretical physics but there is a lot of theoretical physics out there that will never contribute to absolutely anything.

Let's take a look at his "PhD thesis"
https://thesis.library.caltech.edu/2597/
> Some Topics in Theoretical High-Energy Physics
>Wolfram, Stephen (1980) Some Topics in Theoretical High-Energy Physics. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/S6JE-QF83. https://resolver.caltech.edu/CaltechETD:etd-06142007-142536
Abstract
>This thesis discusses various aspects of theoretical high-energy physics. The first two sections describe methods for investigating QCD effects in e⁺e⁻ annihilation to hadrons. The third section presents some predictions for various features of QCD jets. The fourth section shows that any fermions in the standard weak interaction model must have masses ≾100 GeV. In the fifth section, the abundances of any new absolutely stable heavy particles which should have been produced in the early universe are estimated, and found to be inconsistent with observational limits. Finally, the sixth section describes the development of a baryon excess in the very early universe due to B, CP violating interactions.
His own research being what exactly? This is literally compilation plus substitution of data to existing formulas. This is not PhD grade material in my country. You can produce such "PhD thesis" at any age after calculus classes. Which in some parts of the world start around the time you are 17. He either had connections to get such trash accepted as PhD or USA PhD in particle physics is not as amazing as he and his fanboys are portraying it.

Thread derail by idiots in progress...
Anyhow, lets think about "genius" in general. They don't exist. Fraternal orders and cults of Ball along with sundry Mysteries Babylon based mystery cults, not to mention Kaballistic sects, take a frontman and attribute to them a colleciton of "wisdom", sometimes after having surpressed said wisdom for hundreds of years. This alleged Gesius typically becomes a tool for pushing some political goal, in addition to monetizing the tech or "wisdom" the alleged genius presents to the public.
Lets look at Eratosthenes. A man named from birth as Earth-Thoth-ness (via ye ol' occult lame name sound same game) will grow up to think (Thoth) alot about the Earth (Erat, H is silent)...
Sure, whatever. Lets do "his" experiment which Carl Sagan says proves Earth is a sphere... Now I have two AA batteries on my desk. One is standing upright directly beneath my swing-arm desk lamp's light, and casts no shadow. The other battery is standing 18inches away from the first on same said desk and it does cast a shadow. Therefore we can conclude: My desk is a sphere. INSANE!
The air is a lense, so much so that Sunset is Orange/red.
The apparent position of the sun is not the actual position, hence, the shadows are not direct indicators of earth/sun angular relation. Eratosthenes did not correct for lensing of the air and yet NASA says his calculations were spot-on. Clearly the "genius" of Eratosthenes must be called into question, along with Carl Sagan... and NASA. No, clearly Eratosthenes is a fictional character who was probably invented in the Reformation and Spanish Inquisition period, wherein history was rewritten and technology removed & suppressed so it could be doled out to us slowly again. NASA is a gov propaganda arm whose acronym means deception in Yiddish.
And now for Pythagoras, named from birth after Pi-Staggers (sine waves), which he will eventually discover. Take the serpentine S out, you get Pi-Taggers, occult's lame name game sound's the same as Pythagoras. I independantly discovered "trigonometry" trying to build a computer opponent for a SpaceWar game clone made in Qbasic. What took "a genius" like Pythagoras a full decade to discover I had developed in only one hour -- so, I must be a god then, right? Or, you just never tried to figure out things yourself, they threw the solution at you befere you ever were allowed/required to attempt it yourself. Naw, I really am a God of sorts when it comes to code (my atan2() runs ten thousand times quicker and is more accurate than anyone elses implementation). Point being, this "genius" Pythagoras isn't really that smart, but neither are todays mathematicians... Arc Tangent needs only a divide a multiply and one add to solve in any given piece-of-eight of the circle, Cosine and Sine and Tangent are likewise too slow in todays math libs. They're thinking in trig's triangles instead of cartesian squares and circles. I'll eventually publish my code for lain to use... (no, I'm not a god, just a demoscene cracker who con optimize t3h c0d3z for r34lz, and isn't implessed with an admitted math cult's frontman [frantically tatoos a pentagram on his phallus to fit in with the herd])
Lets look at Nicola Tesla. There are etchings from 1631 depicting an electrical demonstration in a French royal's courtyard complete with "Tesla Coils" shooting lightening and men in full plate armor directing the electricity harmlessy across themselves and through their swords. Why, Faraday himself along with Tesla must have time traveled hundreds of years back in time and taught them these tricks -- Or, the "genius" of Faraday, Tesla, Ben Franklin, Eddison, etc. are all frauds. Such proof I will not force feed to you, you have to choose to take the inform yourself, Neo.
Steven Hawking: Teeth fell out and grew back at least once while attaining the Guiness World Record for surviving ALS. Or he's a frontman and [dis]ability figurehead for SocJus (irl IngSoc) ableism identity politics. Anyone can make that chair speak, and alot of ALS sufferers look alike. Has Hawking Radiation ever been observed? No, of course not--Black Holes do not exist. Electromotive forces and refraction better explain the "observations" attributed to black holes. Einstein Rings are blue shifted -- but Gravity lensing should not affect spectra, only direction. We predict blue spectra shift if refraction were the cause: light passes from a less hydrogen saturated intergalactic medium into a dense hydrogen envelope; We MUST witness refractive effects -- but all lensing seen in the heavens MUST be Gravity Lensing or Einstein will have zero evidence fer his bendy syace-time bullshit. In english we might say: Dumb as a box of rocks. In german: dumb as a stone... Ein Stein... the lame name game fake persona Einstein is named after being dumb and is a cometary cataclysm reference to boot. Hawking's work, et. al., depend on the Einsteinian BS. Protip: bendy spacetime was itvented by Einstein's Wife to explain away the uncomfortable fact that inferometers did not detect any rotation of the earth: "experiment must have shrank in the direction of travel" nooope, Earth is not a flying space baal. 1040mph rotation at equator is not relativistic speeds! (They moved the speed goalpost once people started to try and measure bendy cartoon-like spactime)
Now, think about the OP's "genius" in this context. Duh! Of course he's a talentless overrated hack! Nearly all cultural icons are fake "apotheosis" Cult of Personality creations.

your battery example is flawed. the second battery casts a shadow because of the reflection of light within the room. Erastosthenes did his experiment outside, where the suns rays could not reflect off anything and cast a shadow besides from where the suns rays are coming from.
Zhora · 2024-03-21 11:35
>>40127
no that's ridiculous. Do the experiment yourself, if you can't simulate it in your head. The second battery casts a shadow because the light is not shining directly at it, but obliquely at it. An experiment like this with the sun can produce two conclusions, either the sun is close enough that parallax matters, or the sun is far but the earth is not flat. With good clocks, you can make the question into the apparent position of the sun in the sky at a given instant.
From battery 1's perspective, it is Noon. From battery 2's perspective, it is, lets say, 3 o'clock. This is just because the lamp is quite close to the table, so the parallax effect is large.

Also wrong.
Erasthones' experiment measured the angle of the sun overhead at noon. This is something that depends on your latitude. Two measurements are not enough to show that the earth is round: they are only enough to calculate the radius of the earth assuming it is a ball.
To show that the earth is round, you need three measurements. The length of the cast shadow is linear with (north-south) distance between the measurements if and only if the earth is flat.
Aristóteles Amadópulus · 2024-03-21 15:22
>>40131
Addendum: this only would prove that the earth curves in the north-south direction. It could still be a cylinder. To show that it curves in the east-west direction, the easiest way to do that is to use a somewhat accurate clock and figure that the sun rises at different times in different longitudes. Another would be to have people light signal fires when they see the sun rise, and measure how long it takes between when you see the fire and when you see the sun rise. But this is susceptible to the local deformation of the earth's crust messing things up.

Forgive me, the 'looks like 3oclock' statement is somewhat poor wording; in the far north noon often looks like five oclock, if you think noon means sun at zenith, which is what I was suggesting. Such time statements are meaningless in the static world of the desk lamp.
>if and only if the earth is flat
I don't think you're properly accounting for the fact that there are two essential assumptions. First is as you note that the earth is round, second is that the sun's light hits earth in parallel rays.

>First is as you note that the earth is round,
With three measurements (or knowing the latitude of a location where the sun is directly overhead at noon -- constituting a third measurement that you don't have to actually make), this assumption is removed. You could do this experiment on a flat world and you would see a linear relationship, on a round world you do not.
>second is that the sun's light hits earth in parallel rays.
It makes the assumption that the sun is a point light source at a finite distance from the earth, and its rays travel in straight lines. If the sun was infinitely far from the earth and the earth was flat then the angle would never change at all.
Without a proposed alternative theory, this is one which obviously matches lived everyday experience. An alternative theory would have to be tested on its own.

I'm very sorry, I misread this at first.
I suppose you could say that, assuming the sun's rays travel parallel, erasthones' two measurements would show that the earth is round. However you need three measurements to remove this assumption and replace it with "the sun is a point light source and its rays travel in straight lines".

>My physics papers started containing all sorts of amazing formulas.
You can read all of Feynmann's autobiography and immediately realize he's a genius but he's generally embarrassed by his achievements and blames them on boredom and/or curiosity. I don't think he mentions his formulas or research specifics once.
