His contributions to discoveries around DNA are overstated by his own admission. It was mostly all Crick due to his technical background in physics and insights into molecular biology/biophysics. Watson was a chad who wooed Franklin into giving him her data which Crick used to confirm his ideas, but that’s about it. You have to understand that, at the time, molecular biology wasn’t even a field, so Crick and a handful of others who took part in a migration from physics to biology were true pioneers in every sense. Watson is still incredibly based though. His vision, approach to science and commitment to truth are all commendable. He reminds of probably the most based Nobel Prize winner ever, Werner Forßmann (pic. related), who pioneered the field of cardiology. Do yourself a favour and look into that story today

Alot of academic subjects borrow from science for there authority, which itself borrows from maths, and many of them are very shaky rigid constructs. Even alot of physics is shaky.

I love academia but any rigid matrix will get outdated, problem is the courses are too rigid to adapt.

>>13108645
Speaking from experience (data engineer for investment shop).

You're fairly spot-on, but missing the other half of the story. It's largely near-arbitrage (there are incredibly few "true" arbitrage opportunities in the market today), COMBINED with unparalleled access to markets and financing.

The reason RenTech and the like can make so much has little to do with "incredible, near omniscient predictive abilities," but rather incredible access to structured derivative products with more favorable terms. Even more importantly is their access to exchanges. There's a reason quite a few high-frequency and quant shops focus so heavily on establishing proprietary low-latency connections to exchanges; milliseconds advantage can be massive.

In the investment world, much like all other money making operations, it's far less about WHAT you now and far more about HOW you can get an outsized advantage relative to your competitors.

"My Stanford and MIT statisticians are smarter than your Stanford and MIT statisticians," is not a reasonable business model, but brokering access to information, structured instruments and better exchange access sure as hell is.

Also - 95% of modern buy and hold, total return investment management has nothing to do with economics and everything to do with having a knack for predicting investor appetite.

You'd be better of reading investment firm white papers and top financial periodicals to get an idea about what the investment world is buzzing over, rather than learning macroeconomic and game theory.

Economics (which I'd like to distinguish from econometrics) is largely pseudointellectual bullshit used to peddle ideological paradigms.

Just trying to figure out how to do this method of undetermined coefficients question, can someone tell me what the assumed particular solution would be? I've never done a polynomial with a negative degree before so I'm not sure how to approach it.

For the homogeneous solution, I got: c1e^-t + c2e^2t, and seeing as the complementary also have e^-t, should I bump that up with a (t)? Or does the polynomial 3t^-1 make it so that I don't need to bump it up? Fuck, this polynomial to the negative power has me tripped up.

Exactly. Setting aside psyopped alien ships in blurry videos of questionable or even "official" orgin, most of the "themes" of alien encounters by regular people (even in unscientific eras) can be explained as psychological phenomenon of which mass hysteria is only one type. It is not far out science that people report lucid dreaming and sleep paralysis which is consistent with active interaction with "aliens" or getting abducted and probed, unable to move.

We can't even define "consciousness" and we don't even know why we (and other mammals) sleep which one would think is a huge evolutionary disadvantage for an animal that is trying to avoid getting eaten. Psychology (study of the mind) is so primitive today it barely qualifies as a science. Focus on psychology, especially since it is probably a psychological operation (i.e. intentional manipulation) anyway.

One thing that distinguish conspiracy thinking from rational analysis is that when challenged with counter arguments, new arguments are raised instead of questioning their presuppositions. We now live in an era where cameras and people are everywhere and yet these aliens are still "hovering just on the edge of hard observation" as someone noted upstream. xkcd even has a cartoon making this point.

Sounds inaccurate. How about "fringe hysteria"?

Does anyone have a double slit experiment that isn't a simulation where they show that after putting a detector right after the slit to detect which slit the electron/photon/atom passes through, it changes the interference pattern to to slits similar to what would be expected from a particle and not a wave? In every goddamn experiment, they show the first part with the interference patterns, but then just tell you that if you put an observer to detect which slit the particle passes through, the interference pattern changes to two lines, but never actually show this. Something is fucking fishy.

Why do you give a shit about the duble slit experiment then? Interpretations of quantum mechanics is the only interesting thing about it. No one disagrees what happens if you preform the experiment, because QM is so incredibly precise and predictable. You might as well talk about the "Roll a ball down a ramp" experiment. Everyone already agrees on the outcome.

>Why do you give a shit about the duble slit experiment then?
Wave-particle duality.
>Interpretations of quantum mechanics is the only interesting thing about it
Absolutely incorrect. The existence of wave-particle duality is completely independent of the interpretation. What we know for a fact is that photons and electrons exhibit BOTH particle and wave behavior with the double slit experiment. Interpretations of this involve HOW this duality occurs, which is the domain of philosophy. Quit marketing it as physics.
>>
>>13110764
What are you even talking about? I don't think you understand this enough to be arguing about it.

Ill give it ago anyway, because I'm bored.
>The existence of wave-particle duality is completely independent of the interpretation.
Depending what you mean by wave-particle duality, yea this is true. Everyone agrees on QM.

>What we know for a fact is that photons and electrons exhibit BOTH particle and wave behavior with the double slit experiment.
... yea, the whole point of the thought experiment is to point out the apparent stange behavior.

> Interpretations of this involve HOW this duality occurs, which is the domain of philosophy. Quit marketing it as physics
Interpretations of QM involve how QM relate to our actual reality. A mathematical theory of physics doesn't make any claims on what it actually means, no one is claiming otherwise, but its a really strange thing to bring up in a thread talking about the doubleslit experiment.

Also, this was THE topic during the golden age of physics. Take your opinion on QM interpretations being talked about as physics with Einstein, Bohr, Heisenberg and Schrödinger.
>>
>>13110865
>the whole point of the thought experiment is to point out the apparent stange behavior.
What thought experiment? The double slit experiment is just that: an experiment. Any thought experiment is therefore de facto not based on evidence, and hence doesn't elucidate anything about "strange behavior".
>Interpretations of QM involve how QM relate to our actual reality.
Wrong. The FACT that photons and electrons exhibit both wave and particle behavior relates to our actual reality. The INTERPRETATION of such event has no impact on what we measure. Whether the Bohmian pilot-wave interpretation of the Copenhagen interpretation more accurately describes the event is a complete non-sequitur as anything else claimed by it is purely conjecture without other studies done. The more assumptions you bake into your interpretation (MWI, Simulation, etc.) the kookier your interpretation, and the less seriously I take it. Hence when you talk about MWI as the HOW for the wave and particle duality occurring in what we measure, I dismiss it as the nonsense it is.
>its a really strange thing to bring up in a thread talking about the doubleslit experiment.
If by "it's" you mean MWI, I agree.

No, GATE is an afterschool program for extra 'enrichment' but it doesn't really do anything.

You'll live and die the same number of years, and this wouldn't help you get into a better college or career.

If I toss a coin 6 times and it lands on heads those 6 times, if I assume it's not likely to land on heads a 7th time I'm committing a gambler's fallacy.

But if you consider all the possible variations of 7 coin tosses, only 1 of those contains all heads, while there are 7 variations of 6 heads and 1 Tails. Is it not logical to think tails is likelier?

Whats the fault in my judgement?

Gambler's fallacy, probably. HHHHHHH is just as likely as HHHHHHT. Each flip is completely and utterly independent of the previous flip if the coin is fair.
