Science thread Anonymous 115805

Since there's too much talk about moids in our boards, I decided that I should do my part and contribute something non-moid related. So I'm making this thread about science, maths are included as well of course. I personally think that the soft sciences are actually closer to the humanities than to the hard sciences, but in the spirit of avoiding a flame war, I'll try to avoid this point as much as I can from now on.

You can ask questions and discuss stuff about science here, I'll try to answer whatever I can and perhaps attempt to guide posters in the right direction if I'm not familiar with the topic. I'm a physicist by training but I have a basic understanding of general chemistry, geology and biology as well. I know the most about astrophysics and meteorology/climate stuff, I'm OK at mechanics, thermodynamics and quantum physics and not so great at electromagnetism, relativity and maths in general (as in, compared to a mathematician, for a physicist I'm average at maths). Sorry if that came off as a bit pedantic, I just wanted to let you know the kind of stuff I'm more likely to give good answers to.

So yeah, ask away!

Did you study much about crystal structures, science anon? They were my favourite thing in chemistry. I guess there is some cross over if you do physics?

Do you know how fusion power is coming along? I always thought nuclear physics was cool, but was never particularly good at it. Also, what are your thoughts on the current renewable energy scene in general?

>Did you study much about crystal structures, science anon?
Not much, but I had a course dedicated exclusively to solid state physics and as you can imagine crystals were everywhere there. It was cool but I remember that as the chapters progressed the difficulty increased a lot.

>>115815
>Do you know how fusion power is coming along?
I'm pretty sure that the ITER project has been advancing steadily recently, which is very good. Hopefully they will manage to have a working plant prototype that actually produces usable energy for consumption by the middle of the century. Inertial confinement has also had some developments as of lately, I remember watching an interesting video on youtube about a paper on some small breakthrough in the field.

>I always thought nuclear physics was cool, but was never particularly good at it.

Did you study physics in university?

>Also, what are your thoughts on the current renewable energy scene in general?

Storage is one of the two biggest issues in my opinion, especially when it comes to scalability and EROIE, the other one being the availability of some raw materials and how to make sure that we can recycle them effectively to ensure that they have a mostly circular life with many "iterations" before inefficiencies simply take them away from us. There are endangered elements on earth after all, unfortunately. I'm really hoping that perovskite solar cells, concentrating stirling engines and high altitude wind power show their true potential in the short/mid-term future.

Thanks anon, here's to fusion power one day transcending its meme status. I was pretty into the environmental stuff as a kid, and I figured that research into renewables was the most meaningful use of science in the modern day. Did a couple paper review assignments on LCAs for different renewables. Side note, I also did one on on radiative-convective climate modelling. I was so pumped when they announced Manabe as one of the nobel prize laureates this year.

I took physics (and chem) in high school, just graduated lol. I got great grades but since I'm immensely skeptical of abstract concepts (maths included) I figured I'd do biology at uni instead. Last year I got interested in stem cell meat and its potential in disrupting current animal farming processes, which are not great. Any thoughts on this anon? I didn't do biology in school, so I'm taking a gap year to cram.

PS: how did you get into physics? And how was uni?

They're only called soft sciences by people who don't understand them and it goes along with the idea that real science is for men and "soft" science is for women. Not surprisingly OP hasn't studied them.

In reality, it's all science and there's a lot of cross over. They all use experimental techniques, record data, analyze data, etc.

Anonymous 116110

>>116104
They're soft because they're less precise/objective. Mathematical proofs are the closest thing you'll get to the actual "truth". In fields like psychology, you never really know.

Why?

>Any thoughts on this anon?

It's quite interesting, but I think it won't be a super important factor in the future.

>how did you get into physics? And how was uni?

I always liked science and in middle school when the lessons started getting more serious I started to really enjoy what little maths and physics we got, so I decided that I'd study one of those in university. It was hard, but not because the professors were trying to make it hard for us, most of the time the exams were not even that difficult compared to what they could have chosen if they really wanted to utterly destroy us.

>>116098

>What do you consider soft sciences? Things like psychology and sociology?
Yes, that's pretty much the definition.

>I ask because boards like /sci/ sometimes consider anything that is not pure math, like biology, a "soft science"

/sci/ is notorious for being full of either people that know their stuff or complete idiots/trolls. There's almost nothing in between in my experience. Considering that we are talking about 4chan, it would make sense to find something like that.

>I think many softer sciences are making a turn to "harder" methodology thanks to new computational possibilities like ML.

This will help but won't be enough I think.

>(From the last link.) Among the cases presented, the social science paradigms showed the stronger patterns of random copying with invention, including constant turnover in the keywords of highest frequency, and the stochastic ups-and-downs of individual word frequencies over time. In contrast, the physical science paradigms showed a rejection of the neutral model, particularly in the cessation of turnover in the top keywords over time.
>Here is where one naturally seeks an explanation of why the physical science paradigms demonstrated the greater degree of keyword selection. Some physical scientists might like to argue that social scientists invent meaningless jargon, whereas social scientists might claim that they are more creative and free with their language, and their rivals have no imagination.

Not really everything and anything, that's why I said "basically". There are still things we don't understand.

>It makes me wonder how far we are from the real deal

Quite far away I'd say, if we can even get there in the first place. Nothing guarantees that. Or it might just be around the corner, who knows…

>how a real equation that sufficiently explains brain function would look.

I can guarantee you that it would be a multitude of potentially-quite-complex equations instead of just one.

Anonymous 116160

>>116159
>there could be one equation to sufficiently explain brain computation on broad terms
Well, I guess I took the word seriously too seriously in this case. Still, it might not be nearly enough. Even super simple systems like the Vicsek model require more than one equation to be properly described.

I really love science and I used to love the idea of being a researcher but I got burnt out on it after doing it for a few months and realizing that my field was gonna be 50% manual labor and 50% writing boring papers, all under shitty wages and the retarded academic system. Now I'm working a low paying but comfy job in my field and hope I can find better paying work eventually without needing to grab a masters.
Anyways do you guys have any science channels you like? I've been really into astronomy/physics channels lately since I'm not very familiar with them, but they're very cool and awe inspiring. I also really like stuff about biology. Here are some vids I really liked recently:

Do you use a website to discuss science? If so, which one? /sci/ on 4chan doesn't lead to very deep discussion most of the time, and Reddit has all the Reddit problems. I have a Twitter account but I hate that I can't really speak my mind on it. Or maybe there are non-normie bubbles on these websites? I only know of the bay area rationalist/Yudkowsky-esque crowd. There can be some interesting discussion there, but I don't like how Dunning-Kruger it all is when the topic drifts away from compsci/tech.

Does the gas form of water need to be under pressure or within a pressurized vessel to make it steam?

Anonymous 117689

>>117688
>is the gas that comes out of a kettle steam? or just water vapor?
Mostly steam since it's going to be very hot. There will also be more water vapour in that air, even if we ignore all the steam, than in the rest of the air of the room, i.e., it will be more humid.

>Does the gas form of water need to be under pressure or within a pressurized vessel to make it steam?

No, I imagine that you only need to saturate the air with enough hot water vapour to get steam. Think about clouds, they are basically "cold" steam in a sense and they are not pressurised at all.

Try to really get an intuitive understanding of what each term represents, it helps a lot and allows you to piece together the meaning of the equations in your mind. I'm afraid I can't help you much there because I don't remember almost anything, but doing that was super useful back when I had my exam years ago.

Nah. The people who know things don't have time to make long posts. Most of the discussion is made by people who don't really know what they're on about, (highschoolers and freshmen ugrads), but the knowers stick only to certain threads. A strange board indeed. You never know who you're talking to so you might as well not spend to much time there.

Thank fuck I decided to be an engineer. I was originally going to do physics, but stopped myself after my first physics lab class. Physics is really interesting, but I cannot imagine having the patience to carefully conduct physics experiments and calculate complex solutions using non numerical methods.

At least now I have an internship lined up, and likely a job after I graduate.

I'm still taking a shit ton of physics classes outside my major lol.

What are your thoughts on the emerging field of quantum biology?

Anonymous 128689

>>128662
I don't really think anything in particular about it, sometimes you just need quantum stuff to work out how some small things function because classical physics don't cut it. I guess it's not exactly the answer you were hoping for… As for applications, I don't expect anything particularly revolutionary but I'm sure we will learn about some important phenomena, probably ones related to proteins.
