How come they're unable to accurately predict something as commonplace as an earthquake accurately?
They have massive amounts of data to work with, tons of instrumentation and readings to go off of and decades of well measured previous tectonic activity to study. Yet given all that plus enormous budgets to work with and they are still no better at predicting earthquakes than a tarot card reader.
damn, it really do be like that

Science has spoken.
For me, I feel the uncanny valley effect when I see people with blond hair and blue eyes. The weird part is, not all blonde haired blue-eyed people make me feel it, but it's ALWAYS blonde haired blue-eyed people that make me feel it.
Why would blonde haired blue-eyed people make me feel the uncanny valley? Anyone else here get the uncanny valley from certain people?

And no I don't think I'm super clever and somehow thought of something that no mathematician has considered before. It just occurred to me and I know someone has looked into it and I'm curious.
I can sort of wrap my head around the laws of logic, for example, but what exactly makes "2 + 2= 4"? I know that if I see 4 apples, there are "4 of that certain thing" but I'm having trouble defining what that 4 actually is and why it's considered "real" as opposed to just humans coming up with a universal measurement.

In many premature births, the child never reaches puberty.
Newton never had sex because he never hit puberty and never developed those urges. We have his premature birth to thank for all of his scientific contributions.

What gives? This guy wrote an amazing book on GR and it wasn’t even his field.
>We already have New Improved™ Starship™ ready to launch!
It just exploded, it won't be improved with the new data, it will probably explode again.
It's improved based on what? Not on the new data for sure.
If you knew it can explode, wouldn't you fix it before launch?
There's no way they are actually stress testing the components if it keeps exploding like it's the first flight.
The thing must have serious quality issues that can't be fixed without making it too expensive or too heavy.

Why aren't you nolifing your MS paint drawings all over 4chan, anon? You too could brainwash millions of retarded lemmings into adopting whatever memes and vernacular you want, purely by means of astroturfing, to the point where literal politicians and famous people start using it like the dumb cattle they are. Even the people who resist yoyr memes will cave in and submit to them once all their friends and peers start using them, so they'll cuck into using your meme to fit in. Its literally so easy, so why aren't you doing it?
And to make this thread /sci/ related, what are the long term societal and structural consequences of being able to program millions of people just by dedicating yourself to neurotically spamming the same memes over and over again repetitively?

Is there any way to use science to independently verify them?
everyone who procrastinates understands that it's completely irrational. so then why is procrastination such a universal struggle?
do other intelligent species procrastinate as well?
it's like saying that a hill was fine tuned to enable a ball to roll down it.
regardless of what physical laws ended up being, it seems reasonable to assume that if life is capable of emerging from them, then it would.
is it even an interesting question to ask? shit is the way it is because of the way the universe is. a creature without a nose doesn't ask about the smell of a rose.
we only know of one way that life works. and it's within the rules laid out by the one universe we observe, by necessity.
how can we say that if the properties of the universe were different that some other form of life wouldn't emerge instead? or any other manner of shit that isn't possible here but might be possible there?

>Data from ground measurements indicate that the downward (backward) radiation of the atmosphere shows indeed full saturation of the IR CO2 bands and does not support noticeable additional Thermal Forcing (TF) by increasing CO2 in the lower atmosphere… we can expect full saturation already at current concentrations.
This recent paper gives a good explanation of absorption limits and specifically for absorption limits for CO2, it might be of interest to the overwhelming majority of people who never studied enough physics to be able to run through the absorption limit calculation on their own, this includes pretty much everyone who didn't get a PhD in physics with a strong focus on the propagation of radiation.

It can't be for dental health because low IQ people will not be smart enough to care for their teeth properly, they will lack the foresight to do so and/or lack the brainpower to do a good job of it.
The only reasonable explanation seems to be that its done to intentionally reduce people's intelligence. What other reason would make sense?
Now that its know that vegans are unhealthy, can science explain why are vegans so unhealthy?
Should vegans be forced to eat meat in order to have a healthier overall population?
We already vaccinate people in order to make the population healthier so enforcing a healthy diet seems like a logical net step.
Is there anyone where who performed the nofap experiment this year?
If so, what do you think the results of your experiment were?

if you could induce controlled dementia (synapse pruning) combined with psychedelics on a brain that does nothing but solve problems for a period of time, plus the occasional stimulant. that should result in an increase of general ability.

It seemed to make sense that it could be either denying the antecedent or affirming the consequent. This made me wonder if denying the antecedent can always be rephrased as affirming the consequent and vice versa. But when I was going over the reasoning again to figure out if that's the case I got confused.
What the FUCK do you do?
We are taught that an atom is a configuration of protons and neutrons orbited by electrons in an equal number and of opposite charge to the proton number, and that reactions will occur to produce molecules that have a complete "outer shell" of electrons which are therefore stable and unreactive. But how close is this to what's actually going on?
I'm not a /sci/ guy, just a deluded dropout arguing about stuff I don't understand to while away the hours of a long shift by freaking out my colleague. I'd be interested to hear if any of my ramblings have merit and where I can learn more about a more realistic model of atomic anatomy.
The justifications for these statistical tests are a series of asymptotic approximations. They also rely heavily on real analysis to construct continuous distributions from discrete ones so statistics professors just dump the complicated formulas on students as a given without proof or motivation.
With the advent of AI it's time to start teaching statistics completely differently, from the bayesian perspective. The focus needs to be less on ensuring you are making accurate causal assumptions and more on making flexible inferential models.

You would think people with personal doctors would enjoy great health...
In reality they mostly end up drug-addicted and eventually dead from overdose.
For example, why wouldn’t a terrorist get a bunch of weather balloons and attach them to timed detonators that pop the balloon automatically after a few minutes or hours and then attach a bowling ball to them? So there would just be random 16-20 lb bowling balls falling over a mile high at a terminal velocity near 600 mph. Someone would not have to be very bright to do this, yet they could easily get away with it. There are many other plots I can come up with off the top of my head, yet I never see them on the news at all. Why is this? If even one out of a thousand people were crazy enough to do this, society would collapse overnight. Are people just good?
The game has 1 challenge requiring skill (it's not hard, 99% of people can complete it), and then a coin toss game (gamble).
1) If you complete the 1st challenge, you get $10,000 and can obtain the money OR continue to the gamble.
2) The gamble goes as follow: You can lose your $10,000, or you can gain another $20,000, for a total of $30,000.
What is the, matematically, the optimal play, considering hundreds of people will play the game?
A) Always stop after the 1st challenge and take $10,000
B) Always gamble and either lose everything (including the entry fee) OR gain 3x more than you would gain for stopping.
If it's like this:
{a,b}2 = b&a;

>But perhaps the grandest prank on von Neumann was played by Richard Feynman. One day Feynman called von Neumann in his office. Imitating a Swedish accent, he identified himself as a representative of the Nobel Prize committee. He told von Neumann that he had won a Nobel prize in physics, and later that afternoon a delegation would arrive in the auditorium to personally present it to him. Ecstatic, von Neumann rushed to the auditorium during lunchtime, where he found a full audience of his colleagues waiting. Feynman, in a bushy fake moustache and lederhosen, waddled onto stage. He passed a certificate for a "Theoretical Nobel Prize in Physics", and declared that only certainty in quantum mechanics was that von Neumann would contribute anything significant to it.
