Freeman Dyson says global warming is fake
Renown astrophsycist & mathematician Freeman Dyson was certain that global warming is fake. Dyson's resumé is impeccable, a professor at The Institute for Advanced Study, noteworthy and important contributions to number theory, quantum mechanics, nuclear power as well as climate science, which he studied and contributed to for half a century

Here's a video of him saying global warming is fake

Here he is saying its fake in writing
>My first heresy says that all the fuss about global warming is grossly exaggerated. Here I am opposing the holy brotherhood of climate model experts and the crowd of deluded citizens who believe the numbers predicted by the computer models. Of course, they say, I have no degree in meteorology and I am therefore not qualified to speak. But I have studied the climate models and I know what they can do. The models solve the equations of fluid dynamics, and they do a very good job of describing the fluid motions of the atmosphere and the oceans. They do a very poor job of describing the clouds, the dust, the chemistry and the biology of fields and farms and forests. They do not begin to describe the real world that we live in. The real world is muddy and messy and full of things that we do not yet understand. It is much easier for a scientist to sit in an air-conditioned building and run computer models, than to put on winter clothes and measure what is really happening outside in the swamps and the clouds. That is why the climate model experts end up believing their own models.

Why do smart people (STEM) tend to be so cultureless? Nowadays at least.

You'd think your intellect would lead you to searching for beauty and having a more philosophically rich worldview.
But a lot of STEM people tend to be very cultureless and enjoy the dreg of pop culture like everyone else, no refined tastes whatsoever.
Their worldview is usually just the most basic materialistic worldview, held by everyone else. And they think all philosophy is bullshit, not worth indulging.

IQ? do you consider yourself cultured?

What this should tell you is that intelligence is extremely potent at causing biomass increase / gene proliferation. And due to this, if we ever encounter alien life it is very likely that they are intelligent.

Weather disasters decreasing
greta is upset
Bad news fellow climate activists, the dramatic increase in deadly natural disasters we were all hoping for isn't occurring, in fact it turns out that just the opposite is taking place.
>Despite climate-change hysterics, weather disasters have decreased
>A recent scientific study has confirmed what climate realists have been highlighting for some time: Natural and climate-related disasters have been declining rather than increasing during the 21st century.

In a paper published this year in one of the world’s leading journals on environmental hazards, Italian scientists Gianluca Alimonti and Luigi Mariani analyzed the number and temporal trends of natural disasters reported since 1900.

Based on the best available data, the two scientists concluded the 21st century has seen “a decreasing trend [of natural disasters] to 2022” which is “characterized by a significant decline in number of events.”

The researchers emphasized that their conclusion “sits in marked contradiction to earlier analyses by UN bodies which predict an increasing number of natural disasters and impacts in concert with global warming.”

“Our analyses strongly refute this assertion,” they wrote.

For years, international agencies such as the UN Office for Disaster Risk Reduction, the Food and Agriculture Organization of the United Nations, the World Meteorological Organization and the International Red Cross have claimed that climate-related disasters are escalating.

“Weather disasters are striking the world four to five times more often and causing seven times more damage than in the 1970s,” the WMO reported in 2021.

Disaster and weather officials affiliated with the UN claim this dramatic rise is due to global warming: The changing climate, they say, is making weather disasters stronger and more frequent.

Why can't scientists figure out how to get laid?
Does the fact that scientists are too dumb to figure out how to get hot girlfriends and wives despite massive amounts of time and effort devoted to analyzing and experimenting with the issue prove conclusively that scientists are low IQ?
My hypothesis is that scientists invented the IQ concept and IQ tests as a coping mechanism and that their falsely self-assigned high IQ status is just a grandiose delusion that helps them deal with the failure of their sexual lives. If scientists were legitimately smart they would be able figure out how to get the attractive women they lust after instead of jacking off to cartoons or inventing electronic plastic techno-vaginas to have sex with.

What time will display one third?
A typical clock has 12 subdivisions, one for each hour. There are two arms, one for the hour and one for the minute.

In picrel, imagine that the minute hand is perfectly on the '6' subdivision. Then, the hour hand will be perfectly in between the '10' and '11' subdivisions. However, this doesn't produce a perfect angle which is a third of the whole, i.e. 360/3=120 degrees. Each arm is variable and affects the other's placement on the clock.

My question is this: at what time(s) will a clock's hour and minute hands form a perfect 120 degree angle?

I trust that the jannies will see that this question is too stupid to break rule 2. I'm just curious as to what level of math is required to solve this question. I genuinely can't figure it out.

As a earth scientist and a geologist I have come up with a interesting theory, that if you flipped the world over on its axis, everything would turn on its side including houses, roads, and even people. The reason we believe this is because if the earth is spinning on its axis diagonally, but put it horizontally, items on earth would follow earth's gravity and direction making everything turn on its side, what is your thoughts?

There's no Weismann barrier i.e. evolution not only happens through natural selection of information carried by reproductive cells but also through inheritable changes of somatic cells i.e. epigenetics i.e. Lamarck had a point and Dawkin's underestimates the power of memes and the body is not just a vehicle created by genes to carry them to the next generation but all matter is changing itself through many processed besides le genetic mutations and le genetic selection. There are no external forces acting upon matter but matter itself is the force.

So now what? Genes don't control us so let's shape ourselves into chad and get laid. Let's also regulate the deregulations i.e. cure our own disease. Not serious by the way. Why don't le epic epigeneticists never explain constraints?

Olfactory science
>“Did you ever try to measure a smell?” Alexander Graham Bell once asked an audience of graduands at a high school in Washington DC.

>He then quizzed the probably confused class of 1914 as to whether they could tell when one scent was twice the strength of another, or measure the difference between two distinct odours. Eventually, though, he came to the point: “Until you can measure their likenesses and difference, you can have no science of odour,” Bell said. “If you are ambitious to find a new science, measure a smell.”

So how come there is little attention and work has occurred in olfaction versus other fields since smell is an important sense of the body.

I've seen a lot of philosophy threads here. Philosophy fags pretend their field has a lot to do with math and science which is of course bullshit. Reminder that pic related is the most (and perhaps the only) respectable humanities field and it is worthy of the "honorable STEM field" title. History of math and science is the perfect addition to any scientist's education. Whereas stuff like philosophy deals with hundreds years old undecidable disputes that lead to nowhere, history (like STEM fields) deals with facts and objective data - factual people, events and dates. It also utilizes cutting edge technology to study historical artefacts teaming up with other useful sciences. Studying history also seems to be essential in progressing, both in science and in society in general. It also has the least amount of pandering to sjws, in contrast to other humanities.

Stone-age Europeans 'were the first to set foot on North America'

Stone-age Europeans were the first to set foot on North America, beating American Indians by some 10,000 years, new archaeological evidence suggests.
In a discovery that could rewrite the history of the Americas, archaeologists have found a number of stone tools dating back between 19,000 and 26,000 years, and bearing remarkable similarities to those made in Europe.

All of the ancient implements were discovered along the north-east coast of the USA.

The tools could reassert the long dismissed and discredited claim that Europeans in the form of Christopher Columbus and his crew were the first to discover the New World.

Previous discoveries of tools have only been dated back to 15,000 years ago and prompted many archaeologists and historians to question claims that stone-age man managed to migrate to North America.

But the striking resemblance in the way the primitive American tools were made to European ones dating from the same period now suggests a remarkable migration took place.

If the warping of spacetime can exceed the speed of light, then this means that gravitational forces can travel faster than light through warped spacetime.

All reference frames experience local spacetime. This includes singularities. Singularity F experiences an instant in spacetime, moving from T0 to T1. F's past self still exists at T0. We will call this singularity P. The gravitational effect of F exceeds the speed of light and travels through warped spacetime and warps P's spacetime near infinitely and instantly.

The gravitational force of P's singularity cannot over come the gravitational force of F and P explodes in all directions instantly. Spacetime for P instantly expands proportional to the gravitational influence of F. This is what we observe as the first instant of the big bang.

Gravitational strength is inversely proportional to the square of the distance. After the expansion of P's spacetime, the strength of F instantly weakens proportional to the distance to P. We can now think of P as being at T0.000...1 and F still being at T1.

To put this into a different perspective: F is a black hole representing a future singularity. P is a white hole representing a past singularity. Due to the gravitational effects of F, a wormhole opens between P and F. Now the distance between P and F are the length of the wormhole. This wormhole is our flat universe as we presently observe it.

As matter travels through the wormhole, it approaches the future singularity F at T1. As the matter approaches T1 the gravitational influence of F increases. This is what we observe as dark energy or cosmic acceleration. This implies that our universe is within the event horizon of the future singularity. No matter what direction we travel or how fast or slow we travel, we can never escape approaching the future singularity at T1.

When all matter from the past singularity P arrives at T1, what happens?

RETRACTED: Drought sensitivity in mesic forests heightens their vulnerability to climate change

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.

Why didn't iPhones cause people to become smarter and lead to a new renaissance.

Before the internet, it was near impossible to even answer the easiest question like "Why the sky is blue".

glacier growth in antartica
East Antarctic Ice Sheet Thickening & Gaining Mass

A collection of 85-year-old photographs reveals the “growth and stability” of the East Antarctic ice sheet.
More than 2,200 historical aerial photos of a 2,000 km stretch of ice in East Antarctica have been recently uncovered.
The rare images reveal what the glaciers in this region looked like in 1937. The photos show all these East Antarctic glaciers have remained stable, thickened, gained mass, and/or increased in elevation over the last 85 years, with much of the growth and mass gains occurring since 1985.
There has been no warming in this region since the 1950s
>The terrestrial regions of the EAIS respond mainly to atmospheric forcing. Overall, there have been no significant trends in annual or seasonal mean air temperature in East Antarctica since the 1950s, and mean austral summer air temperature (December to February) from stations in all regions rarely exceeds 0 °C

Why We Commit Academic Fraud
Why We Commit Academic Fraud
By Dr. James Heathers, PhD

I like Jay. There’s a lot we don’t agree on, but he’s always stuck me as intelligent, well-intentioned, and decent.

Unfortunately, good people often regard bastardic acts with the same kind of curious detachment we reserve for tigers at the zoo - happy to peer through at them behind the utter certainty of laminated glass, without the slightest inclination to go into the cage and see if the bastard thing will use you as a toothpick.

I respect the sincerity on offer here*, and was not inclined to turn this into a tweet thread that will be swallowed into the morass of porn bots and crypto scams.

So, let’s write it out.


The following will be disorganised, because there is so much to say, but I am hoping a consensus will emerge.

1. The original perspective offered only works if what is more important to you than anything else is finding things out about the world. Only if you have some moral position that values the goals of scientific endeavour. Many scientists do not give a shallow dry fuck about these, not really. They pursue research areas because they are easy, available, or popular. They turn out garbage papers on topics they have no interest in because they are monetizable. Or they regard the whole enterprise as simply a vehicle for their own intensely defective personalities.

Is this an actual thing? How does an increase in section apparently cause a lowering of tensile stregth and yield strenght?

In 144 investigated youth cases, 7 got a heart attack almost instantly after drinking a can of energy drink that contains combo of caffeine+taurine

Normally taurine is got from eating meat. While caffeine comes from coffee (coffee bean products)

Those 7 who received mild heart attack did not experience the same effects again becuase they stopped drinking

Humans and Neanderthals only had sex for a brief period, but it still fundamentally changed our DNA
We might consider Neanderthals to be ancient and unknowable relatives, but humans were once on very intimate terms with them.

Our ancestors, for example, had babies with the shorter, stockier species and swapped DNA for thousands of years.

Studying genomic data from both ancient and modern humans, scientists learned that Neanderthals and humans were having sex around 47,000 years ago then stopped less than 7,000 years later — relatively brief in terms of evolution.

All humans have at least a little Neanderthal DNA, a 2020 study found. These genes may impact everything from metabolism to our risk for diabetes.

Finding out when humans acquired them can help scientists understand how these genes evolved and why they might have been beneficial to our ancestors and stuck around in our DNA for millennia. Neanderthals were living in Asia and Europe when some humans started moving out of Africa. The two groups began having children together shortly after that, sometime between 60,000 and 50,000 years ago.

/nt/ - Nanotechnology general
Thread for the discussion of implementing actual nanotechnology. Nanotechnology is NOT the science of surface features less than 100 nm.

Nanotechnology is the use of nanomachines to build complex products, which may include themselves. This implies self replication and hence provides the basis for the massive productive potential of advanced nanotechnology.

Nanotechnology is probably the most interesting field, since most of it hasn't been written yet!

Bardeen is the only physicist with two Nobel prizes, if anyone should be the most famous 20th century physicist, it should be Bardeen, but instead it's Einstein and Bardeen isn't anywhere near the top of the list of most well known 20th century physicists

As Carbon Dioxide Grows More Abundant, Trees Are Growing Bigger, Study Finds
Trees are feasting on decades of carbon dioxide emissions and growing bigger as a result, according to a new study of U.S. forests.

Scientists tracked wood volume in 10 different tree groups from 1997 to 2017, finding that all except aspen-birch grew larger. Over that same period, carbon dioxide levels went from 363 parts per million to 405 parts per million, owing largely to the burning of fossil fuels. More abundant CO2 accelerates photosynthesis, causing plants to grow faster, a phenomenon known as “carbon fertilization.” The findings were published in the journal Nature Communications.

The study suggests that even as warming threatens forests by fueling drought, insect infestations, and wildfires, rising CO2 levels mean that tree-planting is an increasingly cost-effective method of fighting climate change, as the same number of trees can sequester more carbon, said Brent Sohngen, an environmental scientist at Ohio State University and coauthor of the study.

“While we’re putting billions of tons of carbon dioxide into the atmosphere, we’re actually taking much of it out just by letting our forests grow,” Sohngen said in a statement. “We should be planting more trees and preserving older ones, because at the end of the day they’re probably our best bet for mitigating climate change.”

Science links liberal beliefs to psychotic traits

Science says liberals, not conservatives, are psychotic

Turns out liberals are the real authoritarians.

A political-science journal that published an oft-cited study claiming conservatives were more likely to show traits associated with “psychoticism” now says it got it wrong. Very wrong.

The American Journal of Political Science published a correction this year saying that the 2012 paper has “an error” — and that liberal political beliefs, not conservative ones, are actually linked to psychoticism.

“The interpretation of the coding of the political attitude items in the descriptive and preliminary analyses portion of the manuscript was exactly reversed,” the journal said in the startling correction.

“The descriptive analyses report that those higher in Eysenck’s psychoticism are more conservative, but they are actually more liberal; and where the original manuscript reports those higher in neuroticism and social desirability are more liberal, they are, in fact, more conservative.”

In the paper, psychoticism is associated with traits such as tough-mindedness, risk-taking, sensation-seeking, impulsivity and authoritarianism.

Claims that “97 percent of scientists” agree that a climate catastrophe is looming because of the emission of CO2 should be greeted with skepticism. Traditional science has advanced by comparing observations or experiments with theoretical predictions. If there is agreement with theory, confidence in the theory is increased. If there is disagreement, the theory is abandoned or it is modified and tested again against observations.
Scientific truth has never been established by consensus, for example, by “97 percent agreement.” History reveals many instances when the scientific consensus of the day was later discredited. The widespread embrace and practice of eugenics in the early 1900s; opposition to the theory of plate tectonics in geology; and the dominance of Lysenkoist biology in the Soviet bloc, are a few recent examples. Given the frequency of mistaken consensus, citizens everywhere should heed the Royal Society’s motto and learn as much as they can about how increasing CO2 levels in the atmosphere will affect the planet.

/sci/ Terrence haterz, give ONE valid reason you're not a fan. Hard mode: the reason can't be related to "I'm a dumb bumpkin, and he criticized muh Trump."
I'll go first: I think he's wrong that certain unsolved math problems require collab-maxing. This seems to be an insecure reaction to the fact that Wiles and Perelman didn't collab-max (building upon the work of others is a different story). He also seemed a bit annoyed by the lack of top-tier interest in his Twin Primes Polymath8 collab-maxing project after Yitang Zhang's mini result, as if top-tier number theorists were somehow deficient in character for not wanting to have a flash of genius only to watch Tao's superior marketing and PR tactics relegate their names to historical footnotes.

With all the schizo posts on "AI", here's a serious question: How are today's LLMs not just roided up version of the stuff programmers were doing in the 90's? If you throw enough data and compute at the problem and use sophisticated models like neural networks you can simulate intelligence...but it's still just a simulation. It's not actual intelligence. Sure it's surprising what these probabilistic models can generate with images and video but in the end aren't they just more sophisticated versions of Mark. V Shaney?
