How do I get out of this trap?
It takes too long to learn to program, but it is completely unsustainable to manually enter all my data like this.
But I really want to know if there is a correlation.

you should try using python instead, it's a lot more intuitive for things like data/information processing

Keep trying anonfriend. You're learning the best way possible: necessity. Most people try to learn for the sake of learning, which is really great, but they either get bored of it part way through because of a lack of applications or they have trouble implementing what they've learned due to a lack of practical knowledge.
Get off 4chan and keep trying. You will never feel better than after completing something you've put some real work in to.

Im currently in my final year of undergrad doing a degree in Math and Physics. I have a strong grasp over javascript and python. I was wondering what programming language I should learn next? Im looking primarily at physics(quantum physics or experimental astro) and engineering ( aerospace/ mechanical) for grad school so something that I could use for the future would be great. Im also currently looking into Matlab and R. Any advice on building my skillset would be appreciated.

just learn more physics, learning a language is relatively fast if you already spent some time programming. If you still want to learn something maybe some mathematica (it's very good to know because of it helps you with math, but also intuitive so I wouldn't worry much about it) and C++, you'll learn a bit more about computers and it's used in condensed matter as far as I know. If you do learn C++ learn also a bit about the cost of operations of computers like accessing memory, disk, etc. will make you design better algorithms

>>9072081
for completeness, matlab and R seem good, but unless you're looking for a particular library or something you should be able to learn them in case you need it

OP here, I'll look into C++. I did some Objective C in my first year. Is C++ syntactically/logically similar?

If people lived on Mars without any artificial gravity, how would their bodies change?
Supposedly, we're taller in the mornings due to decompression of the spine as we lie flat.
And then there are those African women with elongated necks, because they were made to wear more and more neck-rings while growing up. We're not made to fit a precise genetic plan; we can be changed to fit a mold, within certain limits.
With that in mind, would Martian gravity lead to giant or elongated humans, assuming we could have normal pregnancies or even sperm motility under martian gravity?

I'm trying to model a small submarine with thrusters on every axis for use in a linear quadratic regulator / Kalman filter. Do you have any recommendations for readings / starting points (textbooks or otherwise) in order to find the differential equations that govern this system? I must also linearize these equations so any pointers here would help tremendously.
I have basic undergrad engineering courses under my belt (calc, ODES, linear algebra etc).
Would something like fluid mechanics or dynamics be the right direction?

Trap the object in a spheroid or a geometrical rigid shape like a triangle or square. Mess around with placements of rotation by approximating via a rigid shape.
From just looking at that we can assume that the dog is a sphere.
Hey /sci/
I desperately need a 470uH inductor to finish a project this weekend and all the electronics stores are closed on Sunday.
Any ideas where I can scout one out|?
I ripped apart a few VHFs I have, but no 470uH...
Making one from an air coil is virtually impossible.

If earth's moon had a magnetic field of itself capable of protecting it from solar winds, would it interfere with earth's magnetic field?
The moon goes through earth's Magnetotail once every cycle

Yes.
The effect depends of the lunar field is aligned with or opposite of the terrestrial field.

>>9071690
If the moon had a magnetic field it would likely slow down and fall to Earth over time due to CEMF. Nuking the moon wont create a magnetic field there btw.

Is a simulated reality inside an everlasting dream on which the dreamer is in a state of coma or sleep possible? Meaning that with the right equipment and the right interference within the brain nerves someone that might be sleeping for a few real time hours (or a much longer time in the case of being comatose) will be in a state of lucid dreaming inside his subconscious and will therefore be able to build an alternate reality inside his own mind; therefore losing all grasp of reality.

You're misusing a long list of concepts. PBS Space Time just did a video that summarizes the question.
One key issue is whether your consciousness is a part of the simulation or whether it has some existence outside it and is being fed sensory stimuli from it. Since there's no evidence that there even is a simulation in the first place, this is all speculation and your guess is as good as mine. Remember there's no particular reason why the laws of science as observed inside a simulation would correspond with those outside.

False definitions ofl phenomenon in poorly constructed human nature, cause sickness to the mind.
For example, a boy and girl represent a shape and a mechanism; so when in a shop thinking about the boys outside, you're likely to think of a human defined boy plus the thought is uncomfortable.
Psychology and it's influence has caused skin-aggression and self-skin-aggression, which is a metaphor of feeding on the child spirit (i.e. secretly harming the future of your own race's children, or other race's children); schizophrenia is automatically a fear if taught in a way where a person cannot think (or speak; confidently) of it imaginitively.
Expect depression; dull views, uncomfortable expression/sense (ill-defined); expect bad luck.

Just take the regular course and email the professor for the honours course to ask if you can come into his/her office hours and maybe grab a syllabus to keep up and discuss with him/her. Most math professors are autistic enough to love talking to students about it.

Well for coca cola you need coca leaf extract.
Today I dreamed of alien invasion. And basically what they did to humans was telepathicly apply a special kind of tests that everyone had to solve (entire planet). Those who didnt pass were to be exterminated i guess.
Does it seem legit ? Do you imagine aliens that way?
