Has a pull ever been observed as opposed to a push? When an object moves, is it being pulled or pushed.

Examples:
>Gas pressure equalizes due to more pushing in greater concentration.
>The sun pushes out photons.

I ask the question in regards to gravity. If a pull has never been otherwise observed, why is the scientific consensus that it is an attractive force? Isn't it more logical and empirical to conclude that mass creates a vacuum toward which some unseen force pushes other mass?

How could gravity reach out and attract something without reaching behind the object and pushing it?

Like so: O -----o<
O = large mass
o = small mass
- = gravitational effect
< = direction of force

No matter how you look at it, mass must create a negative force in order for mass to display attractive qualities.

Thoughts?

Feynman already talked about this in detail.

Newton and others before him struggled with the idea.

What it actually is doesn't matter, only that we can predict the motion.

Can you tl;dr what Feynman said about it? What was his conclusion? "I don't know"?

>>8381175
Feynman is over-idolized.
He was really smart, but people accept too readily that everything he said was 100% true/right.

yeh it becomes super acidic if you mix it with vinegar

its even stronger than stomach acid so make sure to mix it in a metal bowl or pot. it'll eat right through a plastic bowl. also wear rubber dish washing gloves and safety glasses for obvious reasons

if you go to a party store you can get those super balloons, which can inflate super big. those use a different rubber than regular balloons and are resistant to acidic corrosion.

if you fill it into one of those balloons you can make a acid bomb to throw at cars or drop on people :D

Ramanujan is one of the most overrated mathematicians to be honest

yes he was a genius on the level of Gauss, Euler

but in terms of acocmplishments alot of the stuff he just rediscovered

Grothendieck was a much more groundbreaking mathematician, people just like to romanticize Ramanujan's story
>>
Ramanjuan legacy isn't very impressive. He was a brilliant mathematician and could have easily been one of the biggest names had been given the opportunity. Wasted potential

Probably Linus Pauling

I need some advice from a M.D or med school student or something along those lines.

I live in Canada and have a long time history 10+ years of having a pretty serious case of general anxiety as well as chronic depression. I have been on a multitude of anti depressants and anti psychotic medications, most of which have failed and then they try something else.

I have a history of drug abuse (cocaine, alcohol, nicotine, cannabis) but have never been charged with a crime nor have I ever been checked into a mental hospital.

I can't sleep, feel absolutely drained all the time, I feel like an old man but I'm only 24. Every day I think about killing myself but due to my irrational fear of a monotheistic God and a uncertainty of the effectiveness of suicide methods , I don't carry out my thoughts, nor have I ever tried.

My doctor(s) don't seem to think it's a big deal unless I actually try to carry it out. I can't focus, I'm missing tons of time at work, I don't talk to my friends or family.

Anyways long story short I want a quick release benzodiazipine to deal with my acute situational anxiety and I need an amphetamine to help focus at work. I work a mindless trade job where it's not stimulating enough and then all I do is loathe in dread all day. I strongly believe these two medications can help, but the doctors are hesitant to prescribe them due to their high abuse potential, how can I convince these doctors that I need them?

>Benzo to slow you down
>Amphetamine to kick you up

Docbro here, careful with this combo. You can easily get caught in a cycle of taking uppers and downers.

In all honesty, I seriously doubt that you will find a doctor willing to prescribe this combination of drugs. On the face of it, it looks like you either want to sell them or get fucked up on them. Whilst I accept your intentions fully, there is a major risk that you will unintentionally get hooked on both of these agents. Your history of drug abuse is not on your side.

What medications have you tried so far?
>>
>>8380641

MAOI's , SSRI's. And SNRIs.

I can give you specific names of medications, off the top, Prozac, Zoloft, cipralex, celexa.

What should I ask for man I don't know what to do, and I can't keep doing this guessing game of trying a drug for 2 months and then trying another one.

What do I need more? An upper or downer? I was also brefily prescribed a low dosage of a benzo but they never worked.

ITT: tricks you developped to help you understand/memorize harder stuff

I remember when I was in Calculus 1, I started associating noises to my differentiation formulas.

Exemple: d/dx[x^r]=rx^r-1 was the simplest noise (just my mouth swallowing some air slowly and faster toward the end). d/dx[sinx]=cosx was a sort of metallic sound made with my teeth and my tongue (all trigo. functions were metallic sounds btw).
I started using them at first with numerators/denominators in exponents (Idk I was dumb) and then I used them for the calculus.

People kind of laughed during exams but I knew their grades werent as good as mine and the only reason they werent doing it was because they were shy. Im in my Math master's now and I still use these tricks desu they are really helpful.

I find that the more odd or funny a mnemonic is, the more effective it is. For example, when my friend and I were studying for the SATs way back in high school, he came up with this mnemonic for the word 'aspersion.'
"If someone started spreading rumors that I was an ass-person, I would be very mad." His mnemonic for remembering that 'singe' is French for monkey was "that goddamned monkey singed my eyebrows off."

What I'm trying to say is don't be afraid to get creative, even silly.

Can I speak for everyone that ever learned Latin that we have come up with the most embarrassing mnemonics no-one should know about?
