There was a study done at Oak Ridge Lab. by Paul C. Aebersold in 1953 that found that 98 percent of all the atoms in a person’s body change out every year, and that within five years all the atoms had changed.
?????????????????????????????????????????
yup there goes any idea of having a conciousness blown the fuck out.
So /sci how do you explain this one, how are we anything other than a walking computer program, you can replace every atom and its still us so its nothing physical whatsoever, just a program?
>>8110094
This is widely known. Did you derp or do you actually think this somehow related to consciousness? I don't disagree that we are deterministic. Use a dictionary?
>>8110096
well this just proves beyond any doubt there is no physical thing that is a human conciousness.
our "conciousness" is just the program in our brain, it can be recreated on completely new atoms.
>>8110103
It just implies that consciousness isn't a set of atoms.
Hey /sci/, I dont usually post here as I only browse /fit/ and /a/ sometimes, I just fucked a math test today.

try studying if you're not naturally talented.
>>8110044
Thats not what I want anon, I want to be a fucking god amongst men, like be really really good, how you guys do that here?
I just want to prove a point desu, im not intrested in studying anything fancy
I have a year btw.
>>8110047
if you're not naturally talented, you won't be a god.
your efforts will compensate for a while though.
Does anyone know about the engineering physics programs at Stanford and MIT? Is engineering physics a meme, or is it respected and legit? Is it the most difficult engineering major?
> Is it a meme?
Yes, largely. There is no job that calls for the title "Engineering Physicist". This mitigates the main fucking advantage of becoming an engineer.

Being exclusive shouldn't be mistaken for being difficult.
>>8109648
>There is no job that calls for the title "Engineering Physicist".
Plenty of jobs call for the skillset it provides though. Most employers look for an engineering degree related to what their project is about. They won't go oh we were specifically looking for a BME when an EE also has signal processing down. Any employer that autistic you don't want to work for anyway.

There's an Engineering Physics program in Oxford afaik, and the way it works is you learn general stuff the first couple of years, and then you specialise to whatever you want, mech, aero, EE, ChemE etc.
It is the only program they have for engineers, so it definitely isn't a meme, at least in Oxford.
Is the second example not a set because it's not denoted by a capital letter? This seems silly; it would've been a set in complex analysis or linear algebra; why not in topology?

time to find a new textbook
>>8109565
pls anon; I already got attached. ;; I read the prefaces and I feel like I got a personal student-teacher connection with the author and when I read the text, I narrate his voice as though he were an actual lecturer so that I don't get lonely.
>>8109559
Oh god what book is this. {1,2,3} is totally a set.
OP, something else to keep in mind. In ZFC (which is probably secretly the axiom system your book is using), everything is a set. The lowercase/uppercase distinction is used as a convention to help one keep track of what objects are being manipulated, and what is containing those objects. This does not change the fact that everything is a set.
What's the minimum human population required to prevent inbreeding, assuming it's an integrated community?
>>8109438
2.
Inbreeding is an issue only if you are not willing to kill the deformed and inferior.
And soon enough, 1, once the artificial womb is ready.
>>8109438
I read somewhere that to keep deformities to a acceptable rate, the lowest amount would be 20. I have no idea if that's 10/10 or some other ratio however.
Some kind of breeding system would also need to be constructed of course.

The author here mentions an island that was populated using a 20 person 10/10 model, I believe this is what I read.
Basically, it would depend mainly on the amount of healthy/bad recessive genes each person had, but a low number can be achieved.
And if you decide to just live with an incredible amount of deformations, possibly resulting in the creation of a subhuman mutant species, you could go 2 as >>8109441...

How long until we as humans have to skidaddle earth? Will we even survive before we can even fathom the technology to leave earth?
Reminder that the lead-melting, acid-soaked hellhole named Venus is also an Earth-sized planet in a star's "habitable zone".
>>8109496
this is true
>>8109403
>even fathom the technology to leave earth?
If you count solar-orbiting space habitats, we're probably pretty close to that right now.
The "how" isn't the hard part.
Political motivation to allocate funding, even in the private sector is the hurdle.

Is there some special reason why photosynthesis has picked the color green ?
It's more appropriate to say green is the color photosynthesis rejected.
Chlorophyll??
More like BORE-a-phyll.

what does a math major even do after college?
Work for a lame company?
I-I'm scared
And before someone asks, I majored in it because I wanted a personal learning experience. I am pretty damn good at math, but fuck I kind of regret my decision a bit now because no jobs
>>8109385
If you're an applied math major, or specialize in some form of Operations Research, you'll be in like Flynn to get a good job at any large tech or logistics based company.
If you specialize in probability and stochastic systems, you can easily get a job with any quant trader or financial firm with a quant shop. They make good money as well.
If you can do any form of machine learning, you are also in a good position to get a solid job.
If you don't qualify in those areas, aren't...

Not OP here, but need some advice all the same. I'm going to college in the fall and I'm really stuck in between majoring in Applied Mathematics, Actuarial Sciences, or Finance.
I really want to get into Financial Engineering, but my school doesn't offer that major, and Actuarial Science is the closest degree to mixing Finance, Applied Mathematics and Computer Science (mainly programming).
I just don't know if Actuarial Science is very marketable compared to a Math major and Finance minor.

>>Philosophy isn't really that different.
at least philosophy does not pretend to hide some objectivity behind some contrived formal system.

Pretty sure no matter how we constructed the first microscope a cell would look and be able to be acted upon the same way as a cell did the first time someone saw one.
When do trig functions stop being important in college level math.
>>8109295
1) they don't.
2) okay, algebra. But algebra done right will still have some trig by way of examples.
>>8109295
You'll see them again in complex and differential equations.
Don't ever count on something that you don't like going away.
>>8109405
most majors don't have to take diffEQ. they'll come back like the ghost of your wife's husband in calc 2 though
If everything can be predicted if we were to hypothetically be completely aware of all of the atoms and molecules in the universe, doesn't that mean that everything is predestined and free will doesn't exist?

everything can't be predicted though

Legitimate philosophers define free will in such a way that it is compatible with a deterministic universe.
Does the "Intelligent people are more depressed" meme have any basis in reality?
Is there any real science to back up the idea?

This shit is super exciting if it ever became commercially viable.
Just like solar panels but instead of electricity, it would produce storable fuels.

There's other approaches too, like e-diesel and the US Navy's work on synthetic gasoline.
Is it possible to create a weapon that can vaporize water supplies using microwaves (not the appliance) ?
Kind of like in the first batman movie?
This kind of weapon would be invaluable for asymmetrical warfare. What are the physics of this kind of weapon?
>>8109008
>trying to boil water
it's literally the most retarded thing you could ever think of.
>>8109016
what do you mean?
The only microwave based weapon I know of is the Active Denial System.
It's a type of nonlethal weapon that never saw any combat use.
You aim it at people and it heats their water and fat.
It reaches /just/ deep enough into their skin to scald their nerves.
Which is extremely painful.
No long-term damage though.
>>8109018
Not that Anon, but it's a really inefficient way to tamper with water supplies.
