Can an engineer be deluded enough to actually believe he is as important as a scientists?
I mean thats like an oomba loompa thinking hes just as important as Willa Wonka isn't it?

STEM. Science, Technology, Engineering, Math
Science - /sci/
Technology - /g/
Engineering - /diy/ /hm/
Math - /mat/
Math really ought to have it's own board. Its not fair the engineers get two.
>>7741428
>/sci/ - Science & Math
math has a 1/2 board thats all it needs because nobody cares about math
if people really wanted to discuss math there would be more math discussion here
>>7741434
I think math undergrads are a very important demographic in /sci/, at least from what I've seen.
Without the math /sci/ would be nothing but /x/ and /adv/
What would happen if a nuclear bomb exploded inside a gas giant?
When we have the technology to do so, would the experiment justify exploding Jupiter?
>>7741416
That is an interesting idea. It is mainly hydrogen and helium so if we drop a nuke and super increase the temperature, we could have fusion occurring which would hopefully start a chain reaction? There is the question of pressure tho
it's too small to sustain deuterium fusion, so it can't even become a brown dwarf iirc.

Hi /sci/,
I was reading about prime factorization and how only quantum computers have an algorithm which can do it in a reasonable timeframe. Apparently if it becomes practical for very large numbers it could be used to break RSA.
I've just devised a method for doing so. Running on a Celeron G1820 at 2.7ghz it gave me results for 256-bit numbers within a few seconds. I'm going to call it probabilistic prime oscillation for the time being.
Post some numbers so I can factor them and prove it. In the meantime, would anyone like to let me know how this is useful for breaking RSA?

is it easier for an electrical engineer to work as a mech engineer or the other way around?
or would you rather hire an EE as ME or ME as EE?
Hint: electronics is easier.
>>7740968
I'd think that it's easier to learn electronics than mechanics, at least for me it's more difficult to think and model in 3 dimensions than 0.
So every element in our solar system that humans have ever seen came from the star before the sun right?
But that star was quite small.
Is it possible one of those absolutely massive ones can make elements we have never seen before?
It would have millions of times the gravity etc and pressure etc
Thoughts /sci?
Actually the heavier elements weren't created by our sun. Heavy elements are created in the stages before a star goes supernova, and dies. Then during the nova all that material is flung out into space, and eventually some of it ended up here, and we built guns to kill each other with it.
To answer the second question, probably not. Odds are that if that could happen, it would during such a supernova, and then it already would have, since such massive stars have such short lifespans.
does OP say that there already was a star in our system before our sun was even born
>>7740720
This is the definition of star generations. 1st generation stars can only contain hydrogen, helium, and a tiny bit of lithium. Only later generation stars can contain heavier elements.

Is there a way to neutralize hydrofluoric acid that's soaked into leather? We had a spill at the water plant I work at, and I got enough on my boots that my coworkers told me to throw them away. I'd rather not, I just finished breaking them in and so I was wondering if there's a way to neutralize it. If it matters, they're steel toed red wing Wellington boots, and all of the chemical got on the outside.
soak a base into them
Calcium gluconate-gel works if HF comes in contact with skin, dunno if it works with leather as well
>>7739641
hydroFLUORIC? Stuff's no joke. Acid effects on cotton and leather well take some time to appear. I'd toss them for safety. Boots are cheaper than skin graphs.
Okay /sci/ ill make this questions simple. how do you stop psychosis caused by Prescribed 30mg Adderall XR and a whole night of no sleep plus labor (as in work) and dancing. I am pretty sure it is the comedown from the Adderall mixed with me being so tired. But i can't sleep and sorry /sci/ if i dont type right i am just letting my fingers do there thing aha. I took another 30mg Addy about 20 minutes ago because i have a hypothesis of the medician counter reacting its self and give me energy and focus ability, to then be able to function and to calculate the exact time i need to be laying in my bed to fall asleep before i go into Psychoses again. So ill let yall know how that goes haha. but help please and thank you.
Describe your experience with psychosis

>Feeling like something is controlling body and im stuck here watching
>Have a feeling that i can beat this other thing using my body but fail
>I think my eyes are changing colors
>I just saw a white see through cat walk past me and vanish
>I see flying dots and smoke like wavy effects on the walls
I also randomly started dancing
eyes were dilated but i ate roman noodles and that made it go down
that's about it
ya
Maybe when your doctor who prescribed the meds asks you if you've experienced any negative side effects you should tell him you are experiencing psychosis instead of lying to him in order to enable your amphetamine addiction.
Maybe you can switch to ritalin? If amphetamine isn't the drug for you then maybe you should ask to try something different. Either that or get some sleep. I can kinda relate, I'm on 120 mg of vyvanse a day plus 20 mg of straight dexedrine throughout the day to keep me fresh. If I dont get enough sleep I get a bit paranoid for sure.
How can the net amount of entropy of the universe be massively decreased?
>>7739151
Fuck, that is a good question. I feel like I'm being by saying the glass of ice chips is the answer, but after giving it some thought I'm going to say the glass of water.
>>7739151
According our current observations in thermodynamics you can't. universe is a closed system as far as we know.
>>7739158
Yes. Think about the motion of the molecules and their possible states compared to the ice chips. Entropyin some sense is a measurement of how many of these states we can have

Any anons want to talk about visual snow?

They were historically called phosphenes I believe, because people thought it was phosphorous that is trapped in everyone's eyes, but it could only be seen in some occasions. I have zero clue what they really are though. Maybe difficulty differentiating the contrast of some dark things? I don't know.
>>7734546
My sister does experiments where she uses a high intensity magnetic field next to people's heads to induce phosphenes/blind spots. I don't know what the end goal of it is, but she always has enjoyed fucking with people's brains.
Why is /sci/ culture so shit? A lot of the people on here seem to be a hypercompetitive striver faggots. The most successful professors and students I know are chill and relaxed, while the only people I run into regularly with the same "hardcore" attitude /sci/ has are middling grad students and aspergers undergrads who would rather graduate with a 4.0 and their virginity intact than with a 3.8 and years of memories with great friends.
>>7741106
I figure the demographic are undergraduates who ego-boost themselves online because that's what humans do.
The search for knowledge allows one to look down on others and once you get a board full of twats who think their 4.0 makes them great human beings and anyone below that is not worth the time, coupled with anonimity the result is /sci/
Not to mention the popsci only faggots who for some reason try to spout lies and deceive on topics they have no understanding of.

Can plants metabolize aqueous sucrose? Can I keep my Christmas tree alive indefinitely by feeding it sugar water?
If you want to grow plants indoors, you should get into hydroponics. You can buy heaps of stuff online, but the marketplaces can all get pretty crowded at this time of year, so make sure you don't use a proxy filter or anything which can slow you down <:-)
>>7741072
That's not really what I'm asking about. I want to keep my tree alive even though it's indoors away from sunlight. Can I supply it with sugar as an alternative to natural photosynthesis?

Hey /sci/, I haven't done anything with my Biological Engineering degree, and I really want to take it to Med School, are there any books that I can use?
That's the staff of hermes by the way, not the staff of asclepius as proper.
>>7740963
yeah, I just googled "med" and took the first pic I saw.
>>7740938
>are there any books that I can use
for what? the best book would be a book to prepare for the MCAT exam so you can actually get in.
why do you want to go to med school?
