What if we made a robot that can move and sustain and clean itself by burning biological matter and absorbing sunlight for power, and melting metals for parts and then can find another robot which it can team up with to build more robots? If we made it human sized what would happen?

Would it be alive? What if we coded an improvement algorithm to stimulate mutations?
>>
you're basically asking "what if tunnel boring machines could also be concrete factories", in which case they can be if the TBM is attached to a conveyor belt or pneumatic pipeline where the concrete can be collected for later use.

In which case, it's still just a TBM even if it can self-replicate and produce product. It's just a machine, it's not alive and doesn't even require particularly sophisticated electronics (just a cutting head, a vacuum tube, and hydraulic rams to push into the rock).
>>
>>10318653
you're basically taking OPs point and writing a wall of text about it, but you misplace the wall.

The only wall we need is one between mexico and america. what if the concrete factorie robot would build that wall. that would be great.

using sunlight is a much better way to go than using biological matter. It has been shown that there is enough sunlight available to make solar cells from sand in a desert to make more solar cells. And the process used is rather brute force, better processes may be possible:
http://www.molecularassembler.com/KSRM/3.15.htm
Kinematic Self Replicating Machines is a pretty good read in this area. So is NASA's Advanced Automation for Space Missions
https://en.m.wikisource.org/wiki/Advanced_Automation_for_Space_Missions
More recently there's MIT's work on lego like blocks that are versatile enough to make almost anything and probably even a machine capable of assembling them.
http://cba.mit.edu/docs/papers/17.04.11.SelfAssemSpacecraft.pdf
They still need to demonstrate one though
>>human sized
self replicating machines will likely be fairly large
>>alive
arguably yes, but who cares as long as we can make it do something useful
>>mutations
are likely to be bad. Von Neumann's self replicating cellular automata tends not to function when mutations are introduced. There is a pretty big difference between macroscale assembly and what happens at the subcellular level. If you shake around a box of airplane parts you're unlikely to get a plane, if you don't shake biological systems hard enough, they don't function. We can try to emulate biological self assembly at the macroscale, but it's unlikely to be practical. It takes a lot of energy to shake stuff around, and we need larger timescales so that parts can explore the whole space. It is very difficult to self assemble pegs in holes at the macroscale. Misalignment of the peg can lead to irreversible wedging.

>I want to teach myself physics and math is this possible
No. Literally nobody has ever done it.
Everyone says they are going to do just that but they are all ignorant of what it takes.
Nobody has enough self-motivation to sit through 8000 hours (not a hyperbole) of self-study.
Besides, it's not THAT fun. It's a job. It's a lot of work with some reward but the reward is sparse.
Especially at an undergraduate level you are learning forever and never actually applying your knowledge.
So in conclusion.
No.
>>
>>10317962
Why shouldn't it be possible to attain at least a reasonable subset of a proper education in math and physics? OP didn't exactly narrow down the scope of their desired proficiency, but the idea that "literally nobody has ever done it" — whatever "it" is exactly — is completely vacuous.

I need to contact de robert lanza of wake forest university.
Do i have to send them a mail do they can forward my message to him?
Ask them for his email directly?
Pls help,its for developing science
>>
>>10318677
For your ease, please follow these simple step-by-step instructions.

1: Contact professor directly.
2: Wait.
3: Realize they either didn't see your message, or don't care.
4: Repeat previous steps until you get a reply.
A few months later, if you are finally contacted
5a: If the professor expresses interest, you're done. Communicate as necessary.
5b: If it's a restraining order, change email addresses and go back to step 1. If this is your second restraining order, try another group of professors.

Exception: If you never get a reply, but the contacted professor soon releases a paper about the exact thing you were contacting them about, you just got fucked. Don't give your whole idea away if you want an iota of credit.

you should feel blessed anon.

“All I know is that while I’m asleep, I’m never afraid, and I have no hopes, no struggles, no glories — and bless the man who invented sleep, a cloak over all human thought, food that drives away hunger, water that banishes thirst, fire that heats up cold, chill that moderates passion, and, finally, universal currency with which all things can be bought, weight and balance that brings the shepherd and the king, the fool and the wise, to the same level. There’s only one bad thing about sleep, as far as I’ve ever heard, and that is that it resembles death, since there’s very little difference between a sleeping man and a corpse.”

Can I just use citric acid instead of ascorbic acid to turn Copper sulfate into copper powder?
>>
>>10317945
No.
If you want to turn copper salts into metallic copper, you need to reduce copper and in the process oxidize something else.
Ascorbic acid is readily oxidized to dehydroacorbic acid, but citric acid is not easily reduced.

Does the research you do in grad school determine what you can do for the rest of your life?

I'm currently a junior in chemical/nuclear engineering. I am being paid for helping one of my professors with a programming project, and he has made it clear that if I do well on this he would take me on as a research assistant for my masters doing more or less the same thing. The project is basically a toolkit that can be used to simulate complex systems where a ton of different modules are exchanging time-dependent data with each other, and he has said that something like it would be very useful for simulating shit like chemical reprocessing of spent nuclear fuel (which is his area of concentration).

I do enjoy programming, but I really got into my major because I was more interested in designing shit than just modelling, and I don't want to spend the rest of my career writing code. My academic adviser (also the head of my school's nuclear engineering program) has also said that this would probably shunt me into academia rather than working in industry or for the government, which is also something i'd like to avoid. Am I just worrying about nothing here? Can I just do whatever I want once I graduate, career-wise?

Was gonna ask this on /adv/ but apparently that board is just for /r9k/ autists wondering how to get laid.
>>
You'd have completed an undergrad and a masters with no industry work experience, which would be a problem in the way of getting a job there.
But how much of a problem that'd be depends on where you are and your other characteristics, so I'd say to trust your advisor.
>>
>>10318621
I'm doing a co-op semester in next fall, and will probably get another one after that. My professor said he was okay with this as well, so i'll definitely have work experience by the time I graduate.

yes. It will work. Only your attitude can keep you back in education or a disease that directly retards you
