Why does the estimated top speed of tyrannosaurus rex keep getting slower and slower? I remember circa 2003 when it could do 64 km/h, now it's only 28 km/h? What changed?

>>16807957Ambush most likely
>>16808495>day 3>the hadrosaurs haven't noticed my giant fat ass in the bushes yetMaybe they were semi-aquatic and ambushed like crocodillians?

Is /sci/ the board to talk about things like dinosaurs and other early life? I wasn't sure if it was this board or /his/ to post it on
Saw this post where Eric Weinstein was talking about how US govt is intentionally stagnating physics to stop it from creating more powerful tools. Is this true? Is our physics stagnating and how did US govt convince so many to stagnate https://x.com/newstart_2024/status/1975316849207529940
If this was true wouldn't other countries, with governments that aren't deliberately hampering their physics programs, have overtaken the US in physics research?
>>16809306Yes. Which is why it's retarded.
>>16809306Hid argument is that US is psyoping those countries too
>>16809321Super retarded.
>>16809279No, Weinstein is a retard. He is trying to sell his "theory" and generally increase his profile as a public bullshitting faggot.
im trying to design a new transistor.its for a bigger project called the quantum arrow.What are some prohibitions?Any axioms that support tunnels crossing casmir gaps and remaining resonant would be great.im new here
no im not a bot.
>>16808424Noone here actually knows anything about science. Sorry bro.
>>16808424I know a bit about transistors and basically you are not asking a question, you are throwing around buzzwords.Maybe you want to know if the casimir effect, which allegedly happens at short gaps, can have an effect on the behavior of transistors?I cant see how, its just meant to be a small force, many people say it doesnt exist and its just a myth, and those who say its real say its just a tiny force between close conducting surfaces.If your transistor has metal surfaces separated by a small distance.. well it ought to just on the electrodes, then there would be some tiny mechanical force between the, likely insignificant compared to the electrical forces.

Fun fact about solid state physics is that the original voltaic pile made by Alessandro Volta can be seen as a sort of diode junction, or at least related. Really any two materials put closely together with different electronic properties will experience some difussion of electrons one material to another when they are close together, with an associated voltage.
Now that the dust has settled, what the fuck was this guy's deal?Outside of Zojirushi, master's theses topics for regarded American grad students, and a few hentai washing machines, what is the legacy?
>>16808954The Z transform is fairly nice if you work with signals
why is climate science so good, but climate propaganda so bad? they keep getting things right but get embarrassed on the media all the same all the time>https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019GL085378>Retrospectively comparing future model projections to observations provides a robust and independent test of model skill. Here we analyze the performance of climate models published between 1970 and 2007 in projecting future global mean surface temperature (GMST) changes. Models are compared to observations based on both the change in GMST over time and the change in GMST over the change in external forcing. The latter approach accounts for mismatches in model forcings, a potential source of error in model projections independent of the accuracy of model physics. We find that climate models published over the past five decades were skillful in predicting subsequent GMST changes, with most models examined showing warming consistent with observations, particularly when mismatches between model-projected and observationally estimated forcings were taken into account.
>>16809295I'm just saying, oil and coal are still the 2 largest fuels in the world its not like those industries are going to let some pesky regulations tank demand for their product without a fight
>>16809297not largest with electricity generation anymorehttps://www.bbc.com/news/articles/cx2rz08en2po

>>16809311that's good but that is sum of all renewables, i like to count each renewable as its own industry because they don't have much in common with eachother besides "nonfossil and non nuclear"
What is the most fun science to learn while being blind?
>>16807751Not my fault this shit is fun, ok back to basics we need to test the stick on space
>>16807730>What is the most fun science to learn while being blind?learning to see with your tongue, developing audio vision like a bat by clicking your tongue. Yes, look the up
>>16807730Cock science. Dick science. The science of the penis. Learn all about it.
>>16807730Raw physics/mathThings like chemistry,.biology...etc need you to be able to see what's actually happening. Technically as long as you know the exact math you can do physics without seeing the actual mechanisms happen physical. It's how we found planets we couldn't see with a typical telescope.

So if Jesus turned a cup of water into wine, how much energy would be released to fuse the correct amount of hydrogen and oxygen into wine components? Wouldn't the radiation and heat cause a minor catastrophe?
So let me get this straight, god can simply make unlimited wine and fish but he makes us work for it?
>>16806504you're assuming you have a full understanding of how the universe works
>>16809270I can only base my assumptions on known phenomena.
>>16809310which do include recorded miracles done by god, right?
>>16806955Nah, such a being would create a stone it couldn't lift (true) and then lift it anyways (also true). Omnipotence is not constrained by a petty thing called logic. It's beyond that.
I don't know if this is the right board for this, but I need help. I have extreme anxiety, and it's no longer just affecting my mind, but is now affecting my physical body. The problem is this: I can't urinate.My mind is so disturbed and confused that it's turned against me and won't let me have the "pleasure" of urinating.Im feeling the urge to pee all day, but I can't do it.Is this the right place to ask for help with a health problem?

What are some things you know are true, but you just can't prove it yet.Me: Vector and scalar are the same thing.

>>16808433Consciousness is 'fuzzy' in time.I.e, it doesn't exist exactly right now, but can communicate with itself in the past and future to a limited extent.I fully recognize how incredibly schizo that sounds.

Is Infinity supposed to be the highest number?If not, can you do Infinity+1?
>>16809260What about infinity+2? That beats infinity+1.
>>16809260*SIGH*!!!, it depends, what the fuck do you mean by infinity?, read up my manhttps://en.wikipedia.org/wiki/Extended_real_number_linehttps://en.wikipedia.org/wiki/Cardinal_numberhttps://en.wikipedia.org/wiki/Ordinal_number
Infinity2 is more widgets.
>>16809260no, inf isn't a numberInfinity is an unbounded quantity greater than every real number.so it isn't a real number
>>16809260infinity is a setanything + 1 is in the set

Very Large Telescope just gave another big destructive hit to standard science...3I/ATLAS is bleeding nickel at levels no comet should, defying physics, and dwarfing anything we’ve seen before, including Oumuamua and Borisov.>https://x.com/UAPWatchers/status/1973358078935581126
>>16804438But anything we don’t know is automatically everything else out there.
There was a backyard telescope enthusiast that got a really good pic of 3i atlas, an actual photo of what it looks like. I can’t find the pic anywhere. If someone has it can you post it?

Say something nice about him.
>>16809076I give him credit for having his finger on the pulse of big tech and algorithmical engagement for like 15-20 years now. He has probably amassed a fortune, and had fun doing it. Isn't that what we all want, really?
>>16809076I guess he's kinda cute.
His videos were a nice alternative to my shitty textbook for one class I can't remember the subject of now.

Who was the asshole who decided home labs shouldn't exist? why do I got to pay fucking 50 dollars + shipping for each dead mouse I want to use for study? I can just go outside and get like 10 dead mice for free.
>>16809235>why do I got to pay fucking 50 dollars + shipping for each dead mouse I want to use for study?Universities and government agencies have deep pockets and if a program doesn't spend all of it's budget they're punished for it with budget cuts so they're more than happy to pay retarded prices for shit like that. Now it's just the going rate.>I can just go outside and get like 10 dead mice for free.Getting them in the wild introduces confounding variables and so may not pass peer review depending on the study you're trying to publish.
