How do hedge funds do it / sci/? They hire so many math and physics autists
you dont have enough data

>How do hedge funds do it / sci/?
Writing laws via their pet politicians to allow them to leverage with money they don't have and disperse risk onto the taxpayer.

>I USED A MACHINE LEARNING ALGORITHM WHY IS IT SO BAD
... did you not think that they might have actually good machine learning algorithms?
Who /determinist/ here?
I kind of consider myself one, but I'm not sure. I would like to hear your views.
>>7904437
If you're talking about QM and you're a determinism, then you've fundamentally misunderstood [math] a ~ lot [/math] of your lectures.
>>7904452
simple deterministic systems can appear complex and random, quantum mechanics might also be such a system.
>>7904452
I thought it would take more posts to bring QM, but I obviously know this would be important for the discussion.
If I am correct just the Copenhagen interpretation of QM is not deterministic. There are deterministic interpretations of it.
Can you define an ordered set using something like Kurwatowski's definition of ordered pairs?

she's old now, like 30 years old
Why do we still need bytes? Why can't we just address individual bits? 64-bit system can address 16 exabits. Why the hell can't I have a 3-bit integer? Or 11-bit integer? And what is all this structure padding bullshit?
>>7903725
It's the established standard for computer architectures. Everything from CPUs to address busses are designed with that standard in mind.
Nothing to do with technical capability, it's just a standard.

Trying to figure out how to structure a ternary based computer is a fun thought experiment
ay guys,
I'm in that situation. We've all been there. I have a midterm in a week, and I don't know my shit.
however, the class is Real Analysis (rudin's book) and the school is UC Berkeley.
it's a really harshly curved class, with a lot of smart kids. how do I do it? how do I pack 6 weeks of Rudin into one week? I'm about half-way to where I should be
I) Adderall?
2)no sleep?
3) ???
To be honest, it's not really possible to learn proof based math within a short period of time like you can with most subjects.
I have no advice,
>>7903213
>harshly curved class
>needing a curve period
You've failed at life
>>7903229
all stem at Berkeley is curved.
any other advice?
Is smoking weed in anyway remotely helpful to being smarter and/or doing well on tests or school?
If so, is it better to do it immediately before studying, or the test itself, both or neither or something else entirely?

former everyday stoner reporting in
half of my friends are still stoners
i've literally never met a single person who learns better while stoned
i've met a ton of people who are worse
and some people who it doesn't affect at all (in terms of studying)
...and i just took the bait, didn't i?
no
try adderal
>>7903093
Studies show 300% increase in performance if you pack a bowl and light up mid test. Believed to be the interaction of THC, anti cancer cells, God and the munchies.
>the literal sole reason of existence is to fight the universe's passive attrition - the ever-increasing entropy. To contain the accumulated energy so far within the system you control for as long as possible
>therefore, being the most efficient object in the whole universe to accomplish the above, the black holes are the ultimate point of evolution and life - every object's point of existence in this universe is to collapse into a supermassive blackhole and retain the accumulated energy for as long as possible

Nah I think I'll stay in bed

Is that when the planets start fapping to traps and black holes go around saying "WE WUZ STARZ N SHEIT"?

Can you learn trig in 8 hours?
Yes. Go do it.
can you learn solid mechanics in one hour

There, done.
What do you think the odds are that we will develop immortality within our lifetimes? How would one go about studying it or trying to achieve it?
>>7901091
0. Just stop with this pathetic pleading and accept your mortality.
>>7901091
The odds are very high that immortality from tevhnology is within our lifetime's reach in my opinon.surely,social media is the embodiment of what immortals will become.
But you know what?Immortality is a mortal's greedy fantasy.It is misplaced as being a good thing when the bad clearly outweighs the good.
>>7901105
No, no one "accepts" the fact their entire existence will become null in a matter of years. People who claim they can are just ignoring it, which isn't the same. The truth is there is nothing worse than death, if you think we can't stop it, fine, but there really isn't a reason to give a shit about anything then.
level 5 fireball + level 5 fireball does 5 damage turn 1 and 5 damage on turn 2.
Charge + level 5 fireball does 0 damage on turn 1 and 10 damage on turn 2.
Fireball can not crit and has a x% chance to miss.
What levels of x(hit) is fireball+fireball favored over charge+fireball and vice versa
Charge can not miss.(A charged fireball can still miss)

Did oral sex play a part in human evolution?
By selecting mates who's teeth didn't hurt their junk... did our ancestors cause us to not have vicious teeth like most animals?
http://youtu.be/DNLv4-p4Eiw
Teeth are the first stage of digestion, not cock obstacles. Different teeth of different animals are adaptations for that animals diet.
>>7900980
So, it did change out teeth, and now humans are adapted for a diet of cock and pussy?
>>7901001
Compare a nigger
to a human being
and you will see if our teeth evolved much or stayed pretty much the same.

my GPA is 2.8. fucking seriously? how...
Comment too long. Click here to view the full text.

>2.8 GPA
Anyone can write a letter.
Anyone can google a few buzzwords and pretend to be interested on something
Anyone can spend some minutes thinking about the buzzwords and give a plastic 'observation' about a topic.
If you were actually passionate about your subject your GPA would literally 4.0. What excuse do you have for this to not be the casE? How strong is your passion if you couldn't even manage a >3.0 GPA, which is the lowest acceptable grade.
Yes, I mean this. If you graduate with a GPA lower than 3 you might aswell have not gone to university at all.
I'm sorry friendo, you just got the retard treatment a retard like you deserves.
>>7900511
Do you think that there aren't people who have passion and can perform at least okay in classes?
2.8 gpa is pretty fucking mediocre, and is a huge warning to an adviser that research is over your head
Let's just assume one has acquired the fundamentals of logic at around age 12(ish)
Aside from mathematics, does logic exist aside from emotion? For example, don't we exist for emotion? Haven't we evolved through emotion rather than from emotion? I've heard it said that da Vinci had no emotion, but can you really make art without it?
What do you think, /sci/?
Nice meme.

Prove me that 1+1 is not 2

1+1= 11 cuz when u put em together
i think he means the actual people who say that 1 is not really 1
When will we achieve human-level AI?
>>7899875
When our alien overlords who run the simulation we're in give us higher IQ so we can build those AIs.
>>7899875
between 2025-2035

lmao
what makes you think that soon
