Tooth decay is the perfect 'subscribe to stay healthy' model.
And if tooth decay was ever solved, academic institutions and the entire industry would be destroyed, many lives and businesses would be ruined. Absolutely no one, in a position to make a difference, has an interest to do so.
We still use barbaric methods to cope with its effects. We've advanced so far in the fields of chemistry and biology yet nothing has changed about the way we practice dentistry. What gives?

>>14332713 No, HIGH concentrations of sugar kill bacteria. Unless you are constantly filling your mouth with syrup (in which case tooth decay will be the least of your problems), the dilute amounts of sugar in your mouth after a meal will encourage the growth of plaque-forming bacteria that will burn through your enamel and the inner layers with their acidic byproducts.

>>14335826 Yes, probably. There have been recent advancements in regenerative medicine, where a frog was induiced to grow back a cut off leg. (frogs normally can't do that)
Also, in vivo induction if stem cell state has been achieved via use of yamanaka factor.
Also, organoid research is going well, the key problem of vascularisation may be solved soon as they found a rare kind of tumor which can induice it's own vascularisation and that could be replicated.

How do I maximise the chances I get my gf pregnant?
Does cumming in her every day help? What about multiple times a day
Also how do I maximise the chances of having a son, is it true male sperm swim faster

>>14337827 Track her menstrual cycle (there are apps to do this) and cum in her multiple days during her ovulation period. After you cum in her, keep her hips elevated to make gravity help the sperm reach the egg. Abstain a few days before the first fertile day to build up a higher sperm count. Have cold showers to help increase sperm production (your balls need to be cool to produce sperm). You can also increase test and sperm count by working out and getting the right diet/supplements if you aren't already.

can i get some explnations/schematics in 3d math or physics of the human or animals body walking/locomotion pattern and how it repeats its opposing sides symetrically but not in tandem but rather in turns? maybe also how weight, speed, and conditions alters the posture of the gait physically like in quadrupeds?
looking for the detailed functions that produces xyz/world coordinates of sorts of the appendages/skeletons.. in robotics/rigidbody/biomechanism but havent found one complete enough tht includes different variation of the initial gaits
just have to address the skeletal/joints and its location and orientations, no need muscles included, or maybe just a single pair of the limbs to start with

truth be told, i really like the subjects OP asks about and so do a lot of people. it's interesting stuff. but OP is not posting in good faith, or has some other issues going on. it's a waste of time to respond honestly.

>>14337010 >Do people refer him to search for answers outside of this board and outside of 4chan? Yes. Over the last 5-6 weeks of this shit people have posted dozens of papers, guides, tutorial vids, etc.
Response from OP is always the same; they complain that the stuff posted isn't 'exactly' what they're looking for and then demand that someone post a step-by-step for doing the very very specific thing they want done in a very specific engine.
In other words - OP isn't interested in learning any of this stuff, they just want someone to do it for them.

>>14337617 PRA doesn't even have to be consistent for the proof to make sense, in the same way that ZFC doesn't have to be consistent for most of mathematics to still go through. Again, if you don't believe the proof of consistency of PA, please point out which part specifically bothers you. Otherwise, there's nothing to discuss, because you're just salty that one particular system within which the proof can be formalized hasn't been shown to your satisfaction to be consistent, which is irrelevant to the discussion.

>>14337633 Let's look at
https://en.wikipedia.org/wiki/Hilbert%27s_program >Consistency: a proof that no contradiction can be obtained in the formalism of mathematics. This consistency proof should preferably use only "finitistic" reasoning about finite mathematical objects. Gentzen's proof definitely satisfies this, as his proof uses finitistic reasoning and proves Con(PA). It doesn't say anything about the proof being also formalized in some kind of bigger system whose consistency is also proved. What matters is that there is a finitistic proof of Con(PA). End of story.

>>14337652 Anon, read the article you are linking. Hilbert wanted a set of axioms that he would base the entirety of mathematics on. That set of axioms is the starting point. That set of axioms can't prove its own consistency. Therefore it is not possible to formalize all true mathematical statements within that formal system. You've proved the consistency of that system in PRA+ but you still can't base the entirety of mathematics in what you started with. If, however, you chose to make PRA+ your starting point, now you have to prove the consistency of PRA+ instead. That's why the project fails.

>>14337677 Hilbert's grand program has failed, but the specific small portion of the program of proving the consistency of arithmetic with finitary means has succeeded.

>>14337692 I agree with you. You seem interested in Gentzen's proof of consistency of PA. I personally haven't gotten too deep into it. If you are interested in doing so, could you write up an exposition of it, as detailed as you might want?

Since it takes different amounts of energy to heat up or cool down different materials...
Won't you have a thermoelectric/Peltier effect, any time you have two separate metals contacting each other, and an ambient temperature change?
So if I forgot a sheet of copper, on top of a sheet of aluminum, and they're in a room that constantly fluctuates in temperature... If there is something to complete the circuit, there's "free" energy there, right?

>>14337604 Subhumanus Americanus in it's natural habitat promoting its natural behavior. This is what happens when parents are brainwashed by individualism to not give a shit about children, and thus leave them to get raised by the state, and the state taking advantage of this in order to homegrow easy to control cattle.
TL:DR: Parents failed to instill kid with proper hygiene values, and he's probably some crypto-Junkie or/and is depressed - hence neglecting basic rituals.
