Greetings gentlemen.
I recently had my testosterone tested and it is 270 ng/dl. This is obviously unacceptable. Rather than going to a doctor and getting a prescription like a normal person, I have instead purchased bulk enclomiphene citrate powder from a chemical manufacturer. Am I retarded? Or can I feasibly measure and consume doses at home? And if so, what is the procedure for doing so?
>>
>>17054823
>procedure
The procedure I'd recommend if your testosterone is too low is stop consuming slop food and do cardio twice a week.
>fit
yuck

>>17054823
>can I feasibly measure and consume doses at home?
Google machine says the typical range is from 12.5 to 25 mg/day. So you can dose it just fine as long as you have a well calibrated milligram scale.
It's administered orally so no needle related risks.

You're barely below healthy range so start closer to the 12mg dose.


Also, what this guy said:

you could start taking peptides and or nootropics (not meme ones that are glorified vitamins) like Cerebrolysin, Semax, Dihexa, Isrib (make sure you dont have misfolded prions in you before doing this one, the covid spike protein had a prion like region and if you were infected or vaccinated you may have prion disease, if you take this you may create more prions, there are cases of people getting Creutzfeldt-Jakob disease after getting the covid vax, also needs DMSO to become bioavailable, dihexa does too. Funnily enough DMSO can cure prion disease, search up Midwestern Doctor DMSO prions/Creutzfeldt), Epobis, ARA 290, Neboglamine, Tak 653, and Tropisetron to improve your energy, memory, focus, creativity, motivation, mind clarity, and enhance your ability to understand problems. Microdosing LSD and other psychedelics can also bring some of those benefits. They also repair brain damage, including age related degradation, and increase reaction time + hand eye coordination.
You can take them intranasally as well to get more of it directly to your brain, which is especially beneficial for Cerebrolysin since the alternative is injecting it and the recommended dosing that way is 5ml a day which is a lot to inject.
-rupharma.com has cerebrolysin + semax, cosmicnootropic.com has semax
-modernaminos.com/ and umbrellalabs.is have Dihexa
-pglchem.com and isrib.shop have isrib and isrib a15
-jennyschem.com has Ara 290 and Epobis but the 2nd peptide is not listed, you have to email them and ask about Epobis, I confirmed this with someone who bought it from there and posted pics of it + his experiences with it on r*ddit. Make sure you buy the pre vials and not the raw powder as the latter isn't ready for injection
-everychem.com has Tak 653, Tropisetron, and Neboglamine

The old Millennium Problems are closed. The AI-Demiurge went through the list and solved what was left. The board that Hilbert and later the Clay Institute kept is, for the first time, empty.

The goal of this thread is to fill it again, properly this time. With conjectures whose resolution would actually move humanity forward, scientifically, technologically, maybe philosophically. Something closer to what Hegel meant by the Weltgeist working itself out through concrete contradictions than to a list of open problems nobody outside academia cares about.

Rules:
Mathematics only. No "what is consciousness," no "why does the universe exist," nothing that depends on an experiment or observation alone to settle. A submission belongs here only if it's the kind of statement a proof can close, the way Fermat's Last Theorem was closed. Physics-flavored submissions are fine only if the actual open part is a mathematical structure, not an empirical unknown.

State a conjecture, not a question. Something exists or doesn't, something equals something, something reduces to something else. "X exists such that Y" or "no X exists satisfying Y." If it can't be phrased that way, rework it before posting.

One conjecture per post. Formal statement first, then one line on why proving or disproving it matters outside its own field.

This thread is submissions only, no voting yet, but you can attempt proving. Once it dies, a follow up general collects every properly formulated entry and opens a vote. Top 10 by vote count form the final list and we will release our own nmp list. Where it ends up after that is anyone's guess, but it gets written down somewhere.

When I am cold, I know that feeling is being cold. However, when I am not cold I have no idea what being cold feels like. When I remember being cold, I just remember the fact that I was cold not what being cold actually felt like.

To preface this, I am a research agronomist who works with fungi.
I'm also going back to school as a 40 year old, got accepted into a mining engineering program. At the same time, the school that accepted me is working with me on a r43 grant where I am the PI (bioremediation of heavy metal contam soils). I start fall 2027, r43 starts may 2027. How the fuck do i learn calculus in its totality before the fall semester so I can focus on the SBIR grant? I can divert 4-6 hours a week towards study if i can just find a course, learning method, etc that makes calculus not terrifying to a retard like myself?
>>
>>17054563
Khan Academy + supplement with whatever your school uses as a calc textbook. Is this a second undergrad degree? I don't know why you would go back to school at 40 for anything less than a masters, probably for chemical engineering in the domain of metallurgy, unless you're just taking basic bitch courses to satisfy the engineering prereqs.

I would expect you to need STEM level calculus, without the need for proofs beyond some entry level stuff. So I would expect that to be 10-15 CP worth of time, so you are looking down the barrel of 300 - 450 hours of work tops, which would include lectures and exercises as well as exam prep. Assuming a leisurely 4 hours a day, 5 days a week, that is slightly less than 4 months, worst case for calc I+II.

>>17054886
Of course, the true amount of time needed is far less but this is just what it were to boil down to usually with, what, 2-4 hours of lectures and such alone a week?

>>17054563
If you're the PI why don't you just hire a math student or an engineer student with your grant?
To be honest you should just explain your exact situation to AI it'll probably help you better than anything else.
Why? Because I'm an asshole who would tell you to start with rudin or spivak so you don't want my real advice.
Calculus is just words, if you're a grown ass man who forgot the division rule no one gives a fuck. If you can't even trivially derive I'd probably fucking laugh at you though.

The proposed solution of Navier-Stokes formulated in LEAN might contain errors. Discuss.

>>17052716
you can't even check for this anymore. of course no one is just prompting an AI to write out a full manuscript, but AI as a tool is used everywhere. it will be used in the introductory parts of a manuscript to proof read and find references, it will be used to review work. it will be used to derive equations and then checked by the author. no one disclosed they used numpy, computer algebra, or spell checkers, that's what AI is going to be for most people. as for the AI companies' usage, they're going to throw all the tokens they have at solving problems that not even the top academics can do, just like this NS case.

I find it funny how years ago back in 2018 mathematicians and physicists kept calling computer science brainlets.
Every time you posted about studying computer science someone would say >not a science leave this board

and now computer science came along and is improving day by day and is destorying the important problems in both fields such as Navier Stokes and S^6

Now it is scary I wonder what will be the limit and what is next for the average scientist

A 10HP electric motor requires about 8000w. An electric generator connected to a 10HP motor will produce about 6000w. So if you connect the motor to the generator, you'll have a deficit of 2000w. Not useful.

Let's say you connect the 10HP motor to two generators at the same time. That won't do it. The motor's 10HP will be divided equally between the two generators, so each will only get 5HP, and produce about 3000w each. Still produces a 2000w deficit.

The solution is to connect the motor to the two generators in a way that only one of the generators is receiving the full 10HP at a time. That is, the motor essentially takes turns, for half a rotation it gives its full force to one generator, then to the other generator for the other half of the rotation.

Let's say that the generator at full speed rotates at 10k RPM. This means it takes 6 milliseconds for a full rotation. The motor will apply force to one generator for 3 milliseconds, then to the other one for 3 milliseconds.

In both cases, the generator won't have any force applied to it for 3 milliseconds so it will start to slow down without any applied force, but 3 milliseconds isn't enough for it to lose any meaningful amount of speed. Inertia will ensure this. And the 3 milliseconds when it receives force from the motor should be enough to push it back to 10k RPM, and the cycle will continue.

The result is that you have two generators, running with the full force of a 10HP motor, generating about 6000w each, for a total of 12000w. Subtract the 8000w to keep the motor going, and you get a surplus of "Free Electricity" of 4000w, which you can use to power your state-of-the-art computer and spend the day at Reddit, posting about how only a very stupid person believes "Free Energy" is possible.

Idea came from: https://artiesays8.wordpress.com/2025/02/08/using-inertia-based-optimizations-to-improve-the-performance-of-a-generator/

Suppose a pulley system pair of driver and driven. Consider, we can simulate this condition by getting a single driven pulley up to running speed and then powering it at half time from the motor. So we don't even need your rigging.
We can look at any vehicle that is continuously running at a given RPM, what happens if that RPM is cut in half? Why does it slow down? This is true of semis and trains and boats and planes. Conveyors and screws. Any drive train that operates at a steady state speed. Can you explain to me how every drive system doesnt simply enter into a runaway state? For any given speed, it takes half the energy to get drive it. So really it should be driving twice as fast.
Guess inertia isn't the solution after all. Must be the capacitive directance of the modal interaction between conductors and fluxes
>>
the moment you stop for 3 milliseconds, the generator loses energy to friction, and so the next time the motor drives it, it has to use more energy to bring it back to baseline speed, this is a retarded idea, a generator needs constant torque and it has a closed loop system to detect if the speed is sufficient, if its not, the generator reduces electric load delivered which causes voltage and frequency spikes which needs additional electrical infrastructure like capacitor banks, etc to stabilize, unless of course you are using something like a pmsg which is used to drive wind turbines which rely on non constant wind speeds which again will just produce power at the reduced speed the generator is rotating at, so no extra power delusions either way

>what is conservation of energy

The first 3 milliseconds generator 1 receives 24J and generator 2 receives 0J. The second 3 milliseconds generator 1 receives 0J and generator 2 receives 24J. Even at one hundred percent efficiency, over 6 milliseconds the generators have produced 24+24 = 48J of electrical work. Oh wait, over 6 milliseconds you put in 24 + 24 = 48J of work. Do not make a shit bait thread again. herbs
