Do you think humanity will never know what the first digit of Graham's number is? (In base 10)

I've checked a few resources, and it looks like it's hopeless for now. The problem is equivalent to finding the fractional part of an extremely large multiple of log(3).
There are some very hard problems in mathematics, but I think that in a few thousand years, nearly all of them will be solved. But hard computation problems are different; Even if humans will live for another million years, it's possible that it still won't be resolved.
>>8136478
it literally does not matter.
This issue is 100% worthless.
>>8136478
quantum computing might help
>>8136564
No. I mean, sure, who knows, maybe it will, but not in the sense that it would allow us to brute-force the problem.
If a tree falls in the forest, and there’s nobody around to hear, does it make a sound?
Yes.
>>8136466
Sound is just the energy waves travelling through the air processes by the ear.
If there are no ears, there's no sound, but there is still vibrations in the air.
>>8136466
can someone explain the utility of this expression? Someone used it in a message board I was viewing and the concept was lost on me.
must be my autism
Why do we hear the sound waves and see the luminiferous aether waves and not vice-versa.
Do we able to see sound waves if we attach an ear to the optic nerve?
>>8136344
Why can you see things that you remember with your eyes closed?
>>8136344
>will you be able to see sound waves if you plug a microphone into a monitor input
>>8136355
Because excitation from other sources stimulate those parts of the brain.
Post popsci bullshit that makes you cringe af.

Literally anything involving quantum physics. It gets abused constantly in the form of "maybe magical bullshit is possible because muh quantum flapdoodle."
In terms of contributing a specific example to this thread, I was forced to watch this movie in a shitty interdisciplinary studies course back when I was in school and it's the worse thing I've ever seen:

I hate that "maybe we don't know some things therefore MAGIC IS REAL AND SCIENCE PROVES IT" attitude.

>I hate that "maybe we don't know some things therefore MAGIC IS REAL AND SCIENCE PROVES IT" attitude
I hate that radical empiricist "I CAN'T SEE IT SO ITS NOT THERE" attitude.
Hey /sci how can I start to self learn topics of abstract algebra? Books, pages on internet, videos, magazines???
>>8135793
A good source for supplementary reading and extra explainations is Keith Conrads notes (on pretty much everything in algebra):

Looks like you have a book there. Have you tried looking inside of it?
what would it be like to encounter a species that is going across the universe helping other intelligent life forms survive and communicate across the dark abyss that is deep space by giving them advanced technology and scientific theories and methamtical models which advance our abilities to overcome the laws that seem to limit us? i imagine that if we were able to somehow advance our understanding of nature to the extent that we can travel across planets effectively through some form of propulsion, live preservation and extension, and information acquisition and storage, we could go around to try and help assist other sapient beings across the ravages of time without much resistance.
however, how would we respond on the recieving end? would we be distraught and try to attack them?
the /sci/ aspect i'm asking of this is, how universal is our model of nature? what happens to our empirical model if it's confronted by an entirely different approach? we improve our models of course, but not from scratch right? it must be a significant disparity.
an emdrive with billion junction solar cells and cryogenic DNA data storage with superconducting quantum computers manipulating the ship and its abundant sensors/radars is the best approach.
I too would like more advanced methamtical models.

Any recommendations on books that aren't purely textbooks? I've been looking at pic to get ready for grad school.
>>8133978
One of the best intro to Category theory books.
I love this one. Soviet Union has a lot of fun books like this.
>>8133978
Have you found the book to be worth your while?
if mass and energy are the same thing why aren't they expressed in the same units?
>>8133878
Because c has units.
They're not the same thing. They're proportional.
If temperature is just average kinetic energy, why don't they have the same units?
>>8133878
Your premise that mass and energy is the same thing is flawed; If mass and energy was the same, then how would someting massless, like light, have energy?
So we all know that you can factorise the difference of two squares easily, and also for two cubes, but is it possible to factorise the difference of any two numbers raised to the same power in the same way?
What about two numbers raised to different powers?
And what about the sum of two numbers raised to the same (or different) power(s)? Are there any powers that work every time?
Please excuse my use of paint.
read the binomial theorem.
>>8133668
[eqn]a^n - b^n = (a-b) (\sum_{i=1}^{n-1}a^i b^{n-1-i})[/eqn]
>>8133688
Correct me if I'm wrong but isn't binomial theorem is about (a+b)^n ?
I'm looking for stuff on (a^n)+(b^n)
paranoid people removes metadata from files when upload them to internet, but what if some companies hiddes user information inside data, for example in pictures could be an unique id per device in certain pixels.
>>8133289
>what if
That's been done since before the internet and continues today.
Camera pixel noise identifies you anyway
>>8133289
It's already being done. Printers embed their identifiers on every page. Of course it's very well hidden, but government agencies probably have all the documentation.
http://www.instructables.com/id/Yellow-Dots-of-Mystery-Is-Your-Printer-Spying-on-/
It's not too far-fetched to imagine the same being done with digital cameras too...
What does /sci/ think of:
Finance
Accounting
Marketing
Human Resources
Operations Mamagement
Public Relations
areas of study in general?
>>8133261
I've always had the impression that accounting is something that sucks the soul and life out of you
only accounting is a legit undergrad major - maybe finance depending on the program
undergrad finance seems odd
the rest can be done with any type of degree, preferably from a good school
my friend did accounting at usc and came out making good money; now works in tv in nyc
even people that go to cal poly pomona do alright for themselves
>>8133265
It does. And it's boring as shit.
Favorite amphetamine /sci/?
I'm on Adderall IR right now but I soon hope to switch off as the recommended dosage just makes me sleepy, anxious, and makes it hard to study. Thinking about switching to Vyvanse.
>>8132879
Currently using 3-FPM. Research chemical. Works quite well.
I'm rather a fan of the 2,5-Dimethoxy-4-chloro-3-phenyl-4,1-ethyl-diphenchloromethamphetamine

Where exactly did viruses come from, and what purpose do they serve since they are not alive?
Also did viruses facilitate evolution at all, and could we make good viruses and inject them into ourselves to make ourselves evolve or live longer or whatever?
There are good bacterias that fight bad bacterias but the only purpose a virus serves is to rape shit up. Viruses are basically hacking organisms and multiplying using your body as a host meanwhile turning your cells into their cells and slowly changing you into something else, so I don't think there can be any good use for them at all.
>>8145799
>what purpose do they serve
Back to school with you.

Could we extract from say the HIV virus all of its genetic material and make new genetic material and insert it into the virus?
Holy fuck. Physicist here. I've been trying to understand consciousness every day for years and last night I suddenly had a realization so profound I don't think there's a single human being on earth who's thought the same thing. I figured out the consequences this morning and they're fucking Ming boggling.
The consequences were somethings I thought of several years ago, but thought it was too ridiculous to be true.
Can't wait to prove how full of shit and what a faggot I am.
