@JD4239 @LensScientific Well I wouldn't call it a simulation if the condition isn't close at all. Simulation for a small RC plane maybe.

@ItsTrippyTurtle @LensScientific They just said to simulate. Nothing about numbers

Turbulent air flow around the landing gear of a Boeing 777X
[This took over 1 million processor hours to simulate]
English
@JD4239 @LensScientific You would not get anywhere close to the correct Reynolds number.

@LensScientific A 3d printer some smoke and a fan would have this done in under 8 hrs

@quantizor @LensScientific @ArbitraryOstric Training the model for the range of scenarios takes more computation than just simulating it, and then you risk not following conservation laws. There has been work on this for airfoils, but its moot since xfoil can give you more accurate predictions at a fraction of the cost.
English
@LensScientific @ArbitraryOstric Crazy to think this probably can be trained into a model that runs in realtime and we just haven't gotten to it yet

@NASA @astro_reid Hi,
I need a link to the highest resolution version of these images,
Thank you.
English
@ConfidenceNzewi @NASA @astro_reid Thats probably for a photo of the Earth in direct sunlight. Here its illuminated by the reflected light off the moon.

@NASA @astro_reid I thought they said stars aren't visible if you expose for esrth to be properly exposed.

@NASA @astro_reid The earth didn’t spin in those minutes?

@betransformed__ @RandBoyo @DeeWaynee94 Centripetal acceleration equals velocity squared divided by radius. Plug in the values for the Earth at the equator, and compare that to the acceleration of a plane.

You don’t feel constant motion, you feel changes in motion.
Same reason you can sit calmly on a plane doing 500mph and not get flung into the toilet.
Flat-earth logic is just physics illiteracy with confidence.

We know the Earth is flat and doesnt move. We know this because we can't feel the Earth Move. Does the Earth feel like its Moving?
English
@RandBoyo @DeeWaynee94 Next time you are on a plane or train at cruise, drop something and note if it flings backwards at the same speed as the plane/train.

@TheGirondin @KyleTrainEmoji Under Biden and Obama, NASA was pretty supportive of SpaceX. Twitter leftists complaining are not a real political force. Early in Trumps term, there was a lot of chaos in the science community, and while its not as bad as initially thought, its still lower funding than before.

@KyleTrainEmoji *gestures at left wing backlash to SpaceX and the Artimes moon program*

I haven't seen the film yet, but I've read the book, and I found it be intensely political. It portrays centralized political authority as a necessity, is strongly pro-science research and education, and the protagonist chooses to forfeit his life to save the lives of foreigners.

I know I'm late to the party, but FYI "Project Hail Mary" is a really fun movie. We took our 9, 13, and 15 yo, and loved it. Not a remake, not a franchise, no political agendas, no sex scenes, no swearing I can remember. Some intensity. It was just a good story.

@BonklerJingus @itssmoli @oktruetho The only one I've seen have the full 70 mm frame released was the Synder Cut.
English
@itssmoli @oktruetho I think there's rips u can download with the aspect ratio but I could be wrong
English
I would buy a tv with the 70mm aspect ratio just for movies

Project Hail Mary on IMAX 70MM vs regular scope screens

@RossPhilbin @FemboyDCS @Trans_FinGol I always think of pounds as a force/weight. Its the pound mass thats the issue, so I tend to use slugs if needed.
English
@FemboyDCS @Trans_FinGol It only makes any sense on earth, and even then g doesn't haven't a constant value everywhere on earth. Pounds-force is the worst unit in existence

@redaction I'm more surprised by the sample size of the data. n=950K, how the hell.

@Level4glitcher @uwunetes Mincraft modding already gets stuck at various versions. Like people were happily playing new 1.7 or 1.12 mod packs years after those versions came out.

@shinchaf1 @ChildOfKhan_ Tech literacy is down in younger people, as they are less familiar with file directories.

@nixonfan23 @BnejiBneji5 @_FloridaBoy__ People have their preferences, Americans are not all one blob of people. Some people don't value having to maintain their own yards, and would rather have city living for convenience.
English
@BnejiBneji5 @_FloridaBoy__ An entire apartment building in an urban area is obviously going to be more expensive than a single family home. That doesn’t mean Americans don’t prefer suburban living. (We’re talking about America, btw. You guys think differently over there)

US Sprawl gets maligned a lot online but we all know which city we’d rather live in between these two extremes

@TrueSlazac Nah the burgers are way too tall instead of wide.

The uncomfortable truth about millennials burgers is that they taste pretty good

I’m surprised no storm chasers or meteorologists in this community are taking about how a huge nail to our community is occurring.
The Trump Admin is going forward removing the supercomputer at NCAR.
This supercomputer is where we develop research for weather models, physics cores, climate dynamics, MPAS, ensembles, WRF and improving the current models we use daily.
Taking this away would deprecate the meteorological community significantly.

@elevenchars @EmeryEXP Yea, a big part of DEI was for veterans and other military people. What a stupid self own.

@EmeryEXP MIT has a naval architecture program that is specifically limited to members of the US military + our allies. What an own goal

@Raw_Dawgs09 @wsdot @wsdot_traffic Its not like there is enough parking spaces, nothings stopping you from trying to waste your time driving and looking for one.

@wsdot @wsdot_traffic You really think our god awful public transit has the infrastructure to move that many people? Be realistic

BEEP BEEP THE HAWKS ARE BACK IN SEATTLE. And so are 750,000 of your closest friends, all coming to Seattle to celebrate our SUPER BOWL CHAMPS.
So if you're heading to Seattle tomorrow, take whatever ferry, bus, train, or spinning teacup is closest to you. Please.
