>physics vs. computer '''''''''''''''''science'''''''''''''''''
>same uni, same year, same problem set #
will you insist on implying cs is worth anything?
I don't know looks like the physicists have it easy. I remember being taught about a basis in high school
Tell me that's not the kind of problem sets you get
7 weeks in the spring semester. It's pitiful.

>the basis of your comparison is literally babby's first linear algebra
Sup. So I've been researching some stuff for a story, and I wanted to know how we'd be able to increase the pull of gravity on the Moon. I've seen it mentioned in other science fiction stories of planets/celestial bodies, particularly Ceres, have their rotation increased to induce a similar gravity to Earth's, to make it more comfortable for humans to live on it.
In theory, let's say we could increase the Moon's rotation (I don't know how, but let's just say for argument's sake we could - in one story they suggest a sort of 'train' that runs the equator at high speeds, in the direction of the spin, to gradually increase it over time), would the increased rotation have an effect on gravity? I know gravity is determined by the mass, rather than rotation so it wouldn't technically make gravity feel stronger. But would/could the rotation make a sort of artifical gravity by increasing the amount of centrifugal force a person would feel?
Bear in mind I'm not expert by any measure of this kind of stuff - hence why I'm asking.
increasing the rate of axial spin doesn't make the gravity stronger.
venus rotates super slow but has nearly the same gravity as earth

>increasing the rate of axial spin doesn't make the gravity stronger.
I know. But wouldn't the rotation have some sort of effect on centrifugal force or something? Like the whole theory of creating artifical gravity by having a rotating craft?

>sort of effect on centrifugal force or something? Like the whole theory of creating artifical gravity by having a rotating craft?
Centrifugal force pulls outward.
What board are you from, Anon?
What do you enjoy about Astronomy, /sci/?
Looking at things far away
Big round rocks
>>8022777
It's the science about everything physical there is (along with astrophysics and cosmology which are really just more specialized subdisciplines of astronomy). Hard for an intelligent person not to revere it.
The sad thing is that so far every known place in the Universe (besides most areas of the Earth's surface region) are both entirely void of life as well as utterly and completely hostile to it. But then again, it's just our own problem, not the Universe's. It couldn't care less.
>people rather believe what an arrogant anonymous person on the internet says, than to listen to their professor or people who have actual experience
I don't judge anyone for this. I just want to know if there is a psychological basis for this.

Is bearposting dead? Bearposters seem to have surrendered completely, since we don't see any of them anymore.
>>8022733
yeah there is, its called ignorance
>>8022743
Yeah but why are people this ignorant?

So now Tyson, too, thinks the universe may be a simulation. Also, wasn't it Joe Rogan who introduced Tyson to James Gates Jr's ideas concerning the simulation of reality? What the hell is going on /sci/?
Well I actually got convinced by /sci/ that there are disturbingly strong indications that the laws of physics act like computer simulations. The only thing that isn't quantized is time itself as there is no framerate or smallest indivisible unit that makes up time. But aside from that I'm sold on the idea that it might be easily a simulated reality that we're living in.
>>8022713
>tyson, too
woah a meme TV celebrity """"scientist"""" is convinced. that will surely change my perception of reality.
the only reason black science man ever got semi-famous is because he kinda resembles a black einstein.
What does it even change if we are living in a simulation? I get the curiosity but it won't change much at all.
It's also pretty depressing
Any philosophers on /sci/? Is it just me or is the whole tradition of "continental philosophy" just bullshit? I don't think I will ever understand the world view of people like Heidegger, Sartre, and in particular Derrida who I think is complete fraud. Can someone explain to me how his ideas aren't just complete bullshit he pulled out of his ass?
At least they're not as retarded as "analytic philosophers"
>>8022585
Most modern-day philosophers and sociologists delve into the realm of culture (dealing with ideologies and power-structures, etc.) while science delves into the realm of studying nature. There needs to be a dichotomy when discussing these things.
Sartre simply says that there is no pre-set meaning to existence and that life is absurd by nature. Sartre believed that since we were not bound to any theological deity, we were free. Foucault then came along and said that people weren't free because they were...

Here is a short summation of Derrida for you:
You Can (Not) Interpret
Structuralism sought to explain what the elements of human culture were by analyzing the structures surrounding those cultures. Ultimately, language is the structure of culture (i.e., culture is socially-constructed by language). However, Post-Structuralism argues that language, in and of itself, has a dichotomous contradiction. Simply stated, words can be "ambivalent," as Derrida pointed out, showing how meaning could be...

How true is this statement:
>the harder something is, the more brittle it is
wrong my dick is hard af and it ain't breakin anytime soon nigga #swag
The more things change, the more things stay the same.

It will shatter rather than elastically or plastically deform when a large stress is exerted on it.
That said, do not conflate this with "weak" or "fragile."
Magnetic waves cannot affect the human's electrical system.
>>8022139
>>8022139
The "human electrical system" is not a circuit, but a series of maintained ion gradients which are allowed to diffuse in set patterns to send signals.
Magnetic fields are not nearly as likely to have a pronounced effect as on a classical electrical circuit.
>>8022149
do you mean non-classical?

Hello /sci/
my friend just today was diagnosed with pre stages of cervical cancer.. just getting as much information as i can as to things that she can too to mitigate this cancer. as well as exercise, anyone have any experience with hemp oil? also things like cutting out dairy or raising ph levels? sources would be fantastic too. THANK YOU.
>>8021945
hey sorry about your friend
i don't think hemp oil or any other magical solution reliably works. talk to your doctors as much as you can and ask them for any suggestions they may have. i read about a guy who supposedly beat his cancer with turmeric and kale but there's no scientific evidence for this. i think the best thing you can do is just try to be healthy, exercise and eat right.
when i got type 1 diabetes the literature was overwhelming, i imagine it's 10000 times worse with cancer....

thankyou for the compassion bro. yeah of course i wasn't implying any magical cure, only looking for external information and evidence based research that could help mitigate the spread.
>>8021945
I've heard of anti-inflammatory drugs reducing the risk of cancer and even slowing it down, so maybe foods that help to reduce inflammation.
Aspirin could also be very effective at this, but there is a huge risk of bleeding. If she is going to try anything, best talk to a doctor first.

Is this what he thinks astronaut suits look like ? Is he crazy or what ?
Do astronauts need to be smart?
Let's be honest, we aren't gonna strap our best and brightest to a fucking explosive and send them to the moon. Astronauts are probably not that smart, but are VERY good at listening to directions.
all they need to do is use tools like hammers and shit to build the experiments actual scientists need to have in space. they are just space construction people. we should send mexicans
>>8021760
you're right
we should send garbagemen into space

Its all about knowing the right people.
