They had some problems inflating the expandable module yesterday. Probably because of higher friction of the materials than initially expected.
Trying again today.
they're releasing short bursts of air into the module and wait for it to settle and then release another short burst.
After yesterdays failure they depressurized it again, however it still expanded a little overnight. (see pic)
What should i practice when i'm going to studies r1 and r2 math next semester? I'm already bad at math but i really want to do my best and succeed somehow, but it have been years since i was on the school bench and i was barely even passing back then, but i also didn't care at all.
Please help me anons.
What are the best programming languages for modelling with PDEs?
I'm looking for something FAST, doesn't matter if the syntax is a total pain in the ass to learn.
What branch of engineering teaches quantum physics/ mechanics
Is convex optimization useful for a CS pleb like me?
What percentage of observations that we make can be predicted?
Let's say you had unlimited computational power, and all of the world's most predictive scientific models were translated into algorithms. How much of what is happening in the real world would you then be able to predict?
What can this even mean?
How can a data format be like a programming language??
Also, how does JSON differ from an (algebraic) data type? Like trees.

According to /sci/, wat do with nuclear waste? Are any long term non sci-fi solutions feasible?
Yes. The really short version is we dig a very deep hole, a "bore hole", and dump the waste down there. Problem solved.
For a longer version, see this link:
We already know the solution: Bury it.
Oklo was effectively a natural Uranium reactor (using rainwater as moderator) that "operated" for hundreds of thousands years nearly 2 billion years ago. Yet despite this, most of the stable fission products and actinides from these "reactors" moved only CENTIMETERS in their veins.
This is not a scientific issue anymore. It is only a political one.
Can East Asian culture be explained by a genetic tendency to produce more oxytocin?
The cult of kawaii. Emphasis on nostalgia for home and childhood. Passive xenophobia. Weird highschool-like circlejerk atmosphere in the workplace. Emphasis on family relationships. More feminine men and more feminine women (not in terms of low testosterone and high estrogen so much as high oxytocin in both.) Meek friendliness to others combined with sense of distance from outsiders. Conformism.
It all fits.
I have a possibly retarded but honest question sci.
There are two balls, i apply force to the first ball and it moves, i apply force to the second ball but it doesn't move, if the first ball move because i applied force to it then did the second ball also not move because i applied a force to it?
What the fuck? Did you apply the same force to both balls? Do both balls bave the same mass? Are both balls on the same surface? Did your parents drop you on your head? Is this bait? Next week, on Dragonball Z....
I did something that annoyed some, they said me doing the thing caused them to be annoyed, i said them being annoyed wasn't caused by the annoyance because that would be similar to saying me doing "something" causes someone that's not annoyed by it to not be annoyed it.
What would be the nutritional value of a bowl of spiders? (Common Jumping Spiders for this purpose) I'm not asking to get /fit/ or anything, I just have to know.
>What would be the nutritional value of a bowl of spiders?
Jesus Christ...I can't believe how desperate you undergraduates get...can't even afford mac n' cheese or ramen...
Is it possible that there's a force that can transform matter to anti-matter and visa versa?
Please explain it to me like I'm an idiot

Can you refine metals by distilling ore?
If you get metals hot enough, they melt and boil right?
So can you distill them?

I'm so sick of this.
The teacher is NOT a professor, it's not difficult to distinguish between academic titles, stop calling your teacher/lecturer a professor. I know you're all still in grade 6, but that's not an excuse for this kind of blatant ignorance.

Solar panel efficiency vs extraction cost? Don't solar panels deplete?
This interests me. However, please be more specific.
Yes, solar cells degrade over time. It's an unavoidable problem IIRC because when solar rays that hit electrons to cause a current, that same process also slowly degrades the solar cell.
What do you mean by extraction cost? And what do you want to know about it and solar panel efficiencies?
Yeah, no chemical process is completely reversible. Everything degrades. It's unavoidable. That being said, I think the issue right now is the total carbon cost of extracting semiconductor materials from the ground. Is it actually carbon neutral, or are we using a fuckton of fossil fuels in the mining and manufacturing process that won't be recouped during the operational lifetime of the PV cells.
"True believers" in renewables will tell you that it will eventually be powered with renewables entirely.
When you do a systems analysis, e.g. an end to end analysis, one finds that solar alone cannot support the production of more solar, and also sustain our modern standard of living. For further reading, I suggest starting here:

My passion I pursue in the academic world involves a lot of math. Unfortunately, a lot of the time it just doesn't click with me. Has anyone ever overcame this struggle?
Everyone on /sci/ seems to be good at math and say so in ways where it seems like it just came inherently.
I will admit I have been one of those people who have came on here and asked for homework help. I'm ashamed about this as I read the textbook and all that good stuff. Oddly enough, the person who is actually willing to help presents in a way that doesn't follow my textbook's...

Everyone who has ever been good at math has dedicated a large portion of their time to studying/practicing/working with math.
No one inherently just understands everything.
The only way you're going to understand math is to just practice, again and again. Only then will you appreciate math.
Every single person on this board with a lick of mathematical knowledge worked hard to obtain and understand that knowledge. Math is hard. But the more you read, think about, and practice math, the easier it will become.
I have a Engineering Physics background among others. In my experience I often didn't understand the more advanced topics we were talking about at the time of learning them (think picking up Quantum and PDEs at the same time). After a few years of feeling that I was flying by the seat of...

I need to generate a sine waveform between 1 Hz and 3 kHz for a shaker. Which function generator do you think would be the best for the job?
>for a shaker
sine waveforms makes lousy protein shakes my dude

It looks like there might actually be some kind of link between cell phone RF emissions and rare gliomas.
Any thoughts on a mechanism? Personally, I'm betting on some kind of blood-brain-barrier disruption that makes it slightly more permeable to carcinogenic compounds, which would explain the low incidence of the tumors in humans.
Anyone on /sci fool around with arduino? Make anything worthwhile? Is it worth getting into?
