A mass with a balloon on it.

>>8825968
No, at least not in the same field, say you have two weights [math] W_1 = W_2 \implies gm_1 = gm_2 \implies m_1=m_2 [/math]

>>8825969
>>8825975
So you would need what ? Different conditions of gravitation (gravity ?) for the 2 objects and it would make the weight vary, but the mass would stay the same ?
Can you change the mass of an object without directly altering it ?

everyones a philosopher.

>>8825884
Yeah, but have you ever talked to actual philosophers?

>>8825886
Yes. They're retarded with their unwarranted egos and personal opinions dressed as some mighty philosophical ideology.

Big-O just says "processing time relative to the number of items you have to process won't rise any faster (on average) than a certain rate". If one algorithm has a larger big-O than another algorithm, that just means that the first algorithm is less efficient than the other one and will take longer to process the same number of items as the other one.

Anon you must be at least 18+ years old to post here. Come back once you complete basic reading comprehension.

Literally just use wolfram or some other calculus calculator that gives you the steps.

>>8825461
Wolfram cost money for steps and I don't find that other calculators give very good steps.

The point of those papers is to learn how to synthesize information you've learned and express ideas based on that. Its the same as doing proofs or exercises, you wouldn't say STEM is doing nothing but memorizing and practicing formulas you'll never use again prepping for a job that is unlikely to require more than a few repetitive calculations.

That said, there's no reason any of those papers couldn't form the basis of an article if they have novel hypothesis or perspective, you'd just have to have a prof invested in you and research time to move forward.

Also speaking as someone who did a history degree knowing i was going to law school, I college as a way to become more well rounded and well read before i delved into law autism for the rest of my life.

>Not being a fedoralord
yeh you are.

As a Poli Sci major, I confront this thought a lot. However, I've gotten good internships so far, and plan to get a doctorate, and I feel its worth it. Is it as profitable as STEM or as useful? Probably not, no. But I enjoy the work and find it fulfilling.

>>8823397
No, because we don't need to as we have the fucking atmosphere we can suck as intake, accelerate and mix to burn our fuel and exhaust that motherfucker at very high speed => thrust.
Why bother then ?

>>8823419
i figured ion thrusters would be capable of higher specific impulse which would make them more fuel efficient, allowing long-duration trips for recon or in atmosphere satellite shit. im just spitballing but i think that it would lead to interesting drone tech if it were ever possible without burning the RF frame into dust.

>>8823429
Ion thrusters are too weak for the friction of our atmosphere. Their benefit take place only in space where you can't throw mass out of your ass ad vitam eternam so you better off make literally every atom count.
Also they are built in a way so they can only work in a vacuum anyway.

For the same reason nobody gets excited over algebra or Calc 1. Take linear 2 and see if you're still excited by it

I never focused on linear algebra because there are already millions of experts in that area. If you like to use linear algebra to describe Nature, then you should do that. Its formalism truncates from the parameter space the ability to define irrational topology. How would you write a pi by Phi matrix?

>>8823339
Both "calc 3" (by this I assume you mean multivariate / vector calc) and diffEQ make very heavy use of linalg techniques. They "feel completely arbitrary" to you because you learned them while not having a foundation in linalg.

For better or for worse, at this point, this is by design.

Back in the 60's and 70's at least, linalg was actually a prerequisite to those courses. You enrolled in undergrad and took calc 1 -> calc 2 -> linalg , in that order, before you could take anything else.

Nowadays, math is taught in "passes" over the same topic, with the "curtain" pulled back a little further on each iteration. First you learned geometry, then you learned trigonometry, then you learned calc2, then you learned basic complex analysis, etc. each time realizing that the "facts" you were taught 2-3 years ago can be derived from the facts you're learning today.

>he didn't get excited over algebra and calc when he was a kid

The intersection of everyone's subjective experiences is what we call objective reality.

>>8823148

No, this is why science simply assumes that we do, because it can't be proven.
>prove you aren't a brain in a jar plugged into a matrix

do you even realise that question makes no sense

The reason as to why i come here is because i want people to look at my brain activity as i die and as im revived. I would also like to experience what death feels like.

Really amazing to see stupid needless regulation getting BTFO. Great to see Republican gov being pro-science. This will create an entirely new industry as many companies move into the space. In addition the approval process has been made easier! Great FDA!

the FDA is establishing criteria, called special controls, which clarify the agency’s expectations in assuring the tests’ accuracy, reliability and clinical relevance. These special controls, when met along with general controls, provide reasonable assurance of safety and effectiveness for these and similar GHR tests.

In addition, the FDA intends to exempt additional 23andMe GHR tests from the FDA’s premarket review, and GHR tests from other makers may be exempt after submitting their first premarket notification. A proposed exemption of this kind would allow other, similar tests to enter the market as quickly as possible and in the least burdensome way, after a one-time FDA review.

This kind of stuff is the real solution to healthcare: free up the market to make cheap alternatives possible, don't fiddle with the way we pay for the current system.

Big steps: let pharmacists fill prescriptions from any source, and make surgery a job which lesser-trained technicians can do, requiring an MD for neither.
