So I'm still deciding whether to study medicine or, what I'm more inclined towards, CS. Why do people trash it? In my country it's free (taxes pay for our public education) and seems to be quite robust for not having a huge educational industry backing it like in the US,.

All of the math and cs stuff I have learned was through youtube videos, reading the book and stack overflow. All my professors either get pissed at me for asking them questions during office hours or just flat out suck at explaining and even sometimes understanding the concepts they are hired to teach.

The trick is to ask questions. People learn differently. Some learn by being explained what to do others learn by being explained what not to do. With room for error ofcourse. Most people learn by excitatory reflexes as you get older they get more attuned or tuned out.

One of my professors whom quit his career to teach always said he had a very smart friend whom went crazy from knowing too much. Ultimately you must create vacant spot for learning. Or else you’ll see yourself playing with acetylcholinase in forcing your brain cells. We first learn through vibration, sound, visual. Then we are told where to put these little symbols and maneuver an idea around. However when we go into a tabula rasa state (all you have learned via memory or repitition is forgotten) we realize we are indulging in our egos. There is nothing there but a ball of mass vibrating sensations. Working upto a headache.

The idea is there are no dumb questions. We can all learn from what not to do as most questions usually involve application. It’s presumptuous for a professor to get mad because they wouldn’t be applying the basic fundamentals of learning. Some people need sensationalization its serves its purpose in better memory preservation. But some are just numb from the repetitive cycles unless they keep their life in margin with new discoveries (incl history) applications and even applicative formats (styles). Means they are dedicated to what they do inside and outside the classroom. What I realize looking at Asian math that they don’t treat their numbers as definite but indefinite. Perhaps there is a psychology behind it.

>> No.11078350

>>11078331
It Latin America they teach numbers with Roman numeral applications. Another theory. They don’t really teach fundamentals in US education or theory. Just application for work. And lots of neglected presumptions. I guess it’s all introduction. You won’t need to apply it fully until your job entitles it. However then you realize you are familiar with some of the stuff. And good to know you at least know the basics. You won’t remember four full years of school completely. It’s not expected.

2 is 3 times the value of three.

if you had twice the amount of money in the bank right now, you would have well over three times the amount of fortune.

you would have all your bills payed, with pocket money left over, and likely 10 times the amount of money in your account.

so in this case

1 x 2 = 55

Scientists believe we are living in a simulation.
David Icke knew this long before they did

Now the proof? I believe it was already discovered years ago. Around 1676, Danish astronomer Ole Roemer became the first person to prove that light travels at a finite speed. Its exact value is 299792458 metres per second. I say that this limitation is the proof of a simulations maximum FPS.

Ah interesting, so the ablative layer is what actually forms your combustion chamber and de-laval nozzle? It should work assuming you can quite accurately predict ablation and lay down your ablative walls accordingly, if any ablation is uneven the burning propellant will presumably exacerbate uneven burning creating unequal flow over it's surface as the shape of chamber, throat and bell become distorted.

>Ah interesting, so the ablative layer is what actually forms your combustion chamber and de-laval nozzle?
Thank you, and yes. The idea being that the ablator can be easily made on a lathe and easily integrated into the rest of the engine. Whereas the more typical design for an ablatively cooled engine would have made the ablator from a composite wrap around a mandrel which is then integrated (or even just wrapped on the engine itself) and all of the headaches from having to attach composites to metal.

>It should work assuming you can quite accurately predict ablation and lay down your ablative walls accordingly, if any ablation is uneven the burning propellant will presumably exacerbate uneven burning creating unequal flow over it's surface as the shape of chamber, throat and bell become distorted.
That is an issue, but I believe that this design can be made robust enough. Also, most of the understanding on how ablators behave require extensive testing which this design is suited for with how easy it is to replace the ablator. The design probably isn't really suited for a rocket, but could work as a test stand article to train on and study liquid propellant engines.

privately i am completely economically liberal and socially libertarian (e.g. free college and healthcare would be good if we could siphon the money off from the .01% and if you want to have sex with whoever, go ahead, that's your business) but as a science person i tend to keep my political opinions to myself in public contexts, like my online presence and public presentations (and even one-on-one i tend to try and feel out the other person before revealing my political leanings).

however, some scientists just go all-out with political statements. i find that inappropriate for the basic reason that if you want to be trusted scientifically, you shouldn't push opinions. of a scientist does that, people whose opinions disagree with that scientist will tend to think the scientist is untrustworthy in general and might distrust even their legitimate scientific results. in other words you dilute the power of your stances on factual science by mixing what you stand for with political opinions.

shit like pic related is just not good for science, as far as i can tell. people like that should just stfu and go back to the lab and do real work instead of meaningless crap like posing for lame political photo ops

It should be context dependent. Scientists have to present a position on issues of health, climate change etc, that requires expert opinion. Even based in fact, they need to present opinion
In the more causal, it's fine to slip a joke in about congress or the token celeb face for either party during a talk or whatever, so long as it's not detracting from the science they are they to convey. The detraction I assign to the presenter, most people aren't going to fixate on one joke about their topic of triggering, and those that do are ignoring the science, so the presenter has to present appropriately.
OP pic is fine, because there is no good scientific justification for patriarchal societies. It's fine then for the scientists to commune it is not a scientifically defensible thing. People that reject the science because it hurts their feelings
