@fishPointer @TetraspaceWest I mean temperature measurement is a voltage, and almost anything conductive can be used as a shitty thermometer, yes

@InigoMontoyaDPR @AdmiralAegis Effects in fluid (including ai) don't scale with size.
English
@AdmiralAegis if we make a surface of these all facing the same direction wouldn't we have a hoverboard?
ok, maybe you have to make them 10 times bigger out of graphene or something but it should be possible.
The manufacturing would be a nightmare.
English
Spoiler: the RPMs are only so high because it's tiny. It can change direction near instantly because it has almost no mass. That's all.
Natalie Wolchover@nattyover
Bacteria move around using a molecular machine called the flagellar motor that rotates faster than the flywheel of a race car engine and switches directions in an instant. After 50 yrs, scientists have finally figured out how it works. “My lifelong quest is now fulfilled.” Link⤵️

A potential new job wants me to sign an agreement that says I cannot work for another additive manufacturing company within 5 years of leaving them.
Is this unreasonable, or just new to me? It feels unreasonable. This is my trade, if they terminate me, I SOL???
English
@recursive_roots @peterrhague Yeah dark matter. Which we see the effect of via gravity.
We also can probe the strong and weak force. We know way more than just electromagnetism.
If it affects things in the universe we can see and quantify it. If it doesn't affect things it's made up and doesn't exist.
English
@ZeframM @peterrhague Put differently: Is there a part of spacetime that is invisible to electromagnetism (but not gravity) in most circumstances, that we don't know about that because all our detection tools are also made out of electromagnetism?
English
Yeah it’s called “the entire electromagnetic spectrum outside visible light”

I thought the whole point of AWS was you can scale on demand. Why is Anthropic so compute limited? Is all the AWS compute sold already?
Good time for the semiconductor industry. Never seen such sustained demand.
English
@jdcmedlock @kylekatarn95 I hear a lot of slopulism from Steyer. Do you think he's overall good?
English
I think it’s unironically great that Our Revolution endorsed the billionaire YIMBY candidate. Policy positions are what matter and he’s the only one serious about taking on prop 13.
New Liberals 🇺🇦🇹🇼🇬🇱🌐@CNLiberalism
The anti-billionaire socialist movement is endorsing the billionaire who is trying to buy the election

@teortaxesTex which is why it was cleared from pressure vessel regs
English
Europeans have some rules I could not even conceive of
ITER@iterorg
Big win for fusion: the French Authority for Nuclear Safety and Radiation Protection cleared the ITER Organization vacuum vessel from pressure rules—recognizing EM forces, not pressure, drive its design. Step toward fit-for-purpose fusion regulation #FusionEnergy #ITER
English
@peterrhague Does the EM spectrum collide with all of spacetime?
English
@henriqworf @peterrhague If it affects the physical world we can use those physical interactions to measure and characterize it. If it doesn't affect the physical world then it's just made up and doesn't matter.
English
@peterrhague No because non-visible light is still light, you can reach the conclusion it exists by reasoning the same way you can with the existence of black holes
OP is talking about an entirely different, alien concept, something our brains literally cannot grasp
English
@peterrhague Not quite, heat energy is something we perceive all the time in frequencies outside of vision. It's just a tactile rather than visual sense.
English
@constans I think it’s the opposite. A healthy economy means that highly skilled people are comfortable enough to stay at jobs they are overqualified for. A bad economy is where everyone is desperate to get higher pay.
English
That means the economy is good. If you find articulate, skilled people at hotels, restaurant, and gas stations, then that means they can’t find better jobs
Benjamin De Kraker@BenjaminDEKR
Have you noticed that core competence of staff for things like hotels, gas stations, restaurants etc has fallen to the point of being almost useless? Nobody seems able to do even the basics of their jobs and this is getting worse.
English
@Authw8 It was sexism really. Purple haired girlboss triggered the nerds.
Nevermind starkiller base was boring and the deaths had no stakes. Hyperspace ramming was breathtaking in theaters.
English
imo it's informative to consider why this move didn't trigger people to nearly the same extent as the Holdo maneuver even though it's probably dumber overall.
the basic rule is that stupid horseshit to ramp up the stakes is more tolerable than stupid horseshit to resolve a conflict.
Star Wars Daily@StarWarsDaily_
Over 155 billion people are killed in The Force Awakrens, making it one of the highest kill counts in cinema history.
English
@vonBarrel @Grizzlestine @ioandtitan @FTFEofficial That is a valid unit. Least objectionable part of the post.
The thing is, it's not 0um. It's like 10^-6 um of Hg
English
English
Lovely strawman, there is no pressure next to a vacuum. There is ONLY a gradient from high to low pressure. And how?
Gravity. Cry more

@TehlohSuwi @miaaowing What part trips you up? I've seen questions about how records work but the hang up is usually understanding how sound works.
English
@miaaowing have you not felt even more stupid after trying to learn how some things work? i tried learning how CDs work multiple times and, nope, my stupid ass still doesn't get it
English
You just know the Apple engineers that were responsible for the triple-camera lens switching system in the iPhone Pro models were sweating bullets watching this hoping the A19 Pro image signal processor would make the right call to focus on the Moon
Reid Wiseman@astro_reid
Only one chance in this lifetime… Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him. I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.
English
@skepticalsports That is not the same as probably p for N tries. Your formula assumes the probably changes each try.
English
That chances of a 1/n event happening in n tries converges quickly on 63% (1-1/e to be exact) has been one of my favorite useful real world math shortcuts since high school.

@eightma27 @Blackymarine How does the astrophage contain neutrinos if they have little interactions with the matter by definition?
English
@ThinkyCrow @xtremeonlinegf Because the CO sensor becomes ineffective after 10 years. And the failure state is no signal.
English
@xtremeonlinegf California is such an obnoxious nanny state they literally outlawed smoke detectors with replaceable batteries. Now you can ONLY buy the ones with 10-year batteries.
English
California is so woke it’s the law for landlords to replace now . Felt awesome being an asshole like this
angel reese stan account@ceewilldotcom
My smoke detector battery is dead for the first time in my adult life. I went to change it and turns out it needs a 9v battery. Like…. Okay no wonder the stereotype exists
