One of the major complaints Wildberger makes is that the contemporary maths student is tricked into believing the current infinitist dogma because the details and foundations are hidden from him. They say that worrying about foundations is the job of a logician. Here take these unjustified axioms and go work with them. Real numbers are usually not "constructed", and even when they are, their properties are never proved to the undergraduate. What's more, what constitutes a proof is never explained. Often universities allow students to assume "knowledge" from high school even though the way the student learned in high school doesn't meet the standards of rigor in the university, making the whole thing quite shaky and disconnected.
So my question is this: is there a book or a resource that explains modern mathematics from the beginning (meaning from the foundations) and without assuming any sneaky outside knowledge?
Is Bourbaki the only project similar to that?

I'm trans and 5'10", and I wanted someone to help check my math- how clockable does my height make me?
The thing I want to figure out is "the probability a woman is trans given she is 5'10" or taller". So A = the probability a given woman is trans, B = the probability a given woman is 5'10" or taller.
Assuming that trans women follow the same height distribution as other AMAB people (which might be changing with more people having the chance for early transition), as per this calculator: https://dqydj.com/height-percentile-calculator-for-men-and-women/ the probability that a woman will be 5'10" or higher given that she's trans is 0.4 given that 5'10" is 60th percentile for male height distribution in the US. So P(B | A) = 0.4
The most common estimate I've heard for how many people are trans is about 1 in 300. So P(A) = 0.00333...
For women in general (cis women being a sufficiently overwhelming majority thereof that trans women won't affect the average substantially), 5'10" is 99th percentile, so P(B) = 0.01
(0.4*0.00333...)/0.01 = 0.1333... or 13.33%. which is 40 times the base rate. Unless there's something wrong with my math it seems like I'm screwed, because a probability 40 times higher than base rate is enough to promote a hypothesis to prominence. What's your view? Should I have posted this on /lgbt/ instead?

I'm trying to do some at home rat surgery stuff and need anesthetic. Tried it with CO2 but I killed the rat.
For 40$I can apply with the DPH to be a "Controlled Substance Practioner" because on their site it says "Scientific Investigator", which I would definitely consider myself! But I feel like they would just say no because I'm 18 and don't even have a degree. And I feel like they'd get mad at me. I want to reach out to local vets about it but I feel like they would also get mad at me.

There is a negative correlation between height and longevity which crosses race and gender barriers seamlessly and it benefits the manlets bigtime. people around 5' tall have the longest life expectancies, everyone else loses a substantial amount of time for every inch taller, about 10 months per inch. So there is a tradeoff between physical size and longevity and I'm wondering if there is a similar relationship between height and IQ because IQ and longevity also correlate. So a negative height to IQ correlation would serve to confirm the speculated IQ-longevity correlation and the speculated height-longevity correlation, both observations seem to have decent data backing them up. inb4 butthurt talltards saying no relationship 2 images | 38 replies Anesthesiology What's it like working as an anesthesiologist?

Of course it is seem that way, people can't do it, how could they see its benefits? I am here to tell you about them >The science of numbers and the art of calculation depend upon pure intelligence in the attainment of pure truth. >Indeed, it most certainly does that. >Have you noticed, too, how people with a talent for calculation are generally quick at every other kind of knowledge; and how training in it makes a slow mind quicker than it would otherwise have been? >I have. >Also, it would not be easy to find many branches of study that require more effort from the learner. For all these reasons we cannot do without this form of training. Plato, The Republic, Book VII Intelligence is the most essential human atribute, it consists on the capacity of aprehending the truth, that is, recognizing something is true https://archived.moe/lit/thread/16639317/ Counting and mental arithmetics not only train important mental abilities like speed of reasoning, attention, memory, but also, intelligence, as every time you count you are exercising your intelligence as you are aprehending a truth so simple it cannot be denied. Everyone that completes the "training" described in the first few chapters of the book in the picture will be prepared for a great career in Mathematics or any other field that require intelligence. Start slowly, count the least of things, count 1 bird, 2 birds flying. Observe people, count them, add one by one in your mind.

It dates to Dynasties 16–17 of the Second Intermediate Period in ancient Egypt, c. 1600 BCE. While other papyri, such as the Ebers Papyrus and London Medical Papyrus, are medical texts based in magic, the Edwin Smith Papyrus presents a rational and scientific approach to medicine in ancient Egypt. >It contains the first known descriptions of the cranial structures, the meninges, the external surface of the brain, the cerebrospinal fluid, and the intracranial pulsations. Here, the word ‘brain’ appears for the first time in any language. The procedures of this papyrus demonstrate an Egyptian level of knowledge of medicines that surpassed that of Hippocrates, who lived 1000 years later. The influence of brain injuries on parts of the body is recognized, such as paralysis. The relationship between the location of a cranial injury and the side of the body affected is also recorded, while crushing injuries of vertebrae were noted to impair motor and sensory functions. Due to its practical nature and the types of trauma investigated, it is believed that the papyrus served as a textbook for the trauma that resulted from military battles. >The papyrus includes a list of the instruments used during those surgeries, instructions for the suturing wounds, and descriptions of using swabs, bandages, adhesive plasters, and cauterizing. Written in black ink, with explanations written in red ink, the papyrus even contains a section on gynecology and one on cosmetics, along with five prescriptions.

That same class of machines, called polymerases, also build RNA messages, which are like notes copied from the central DNA repository of recipes, so they can be read more efficiently into proteins. But polymerases were thought to only work in one direction DNA into DNA or RNA. This prevents RNA messages from being rewritten back into the master recipe book of genomic DNA. Now, Thomas Jefferson University researchers provide the first evidence that RNA segments can be written back into DNA, which potentially challenges the central dogma in biology and could have wide implications affecting many fields of biology. https://www.sciencedaily.com/releases/2021/06/210611174037.htm wtf 1 images | 3 replies No title How is this supposed to test intelligence?

Just check the daily deaths graph and verify my statement that "there is no sign of a detectable deviation from oscillations near zero". >Why are the "cases" increasing but the daily deaths (and even hospital admissions) stay near zero? It's simple. You may trace the new revival of Covid to a new variant. They started to be labeled by Greek letters (because the more descriptive nation-based names are considered politically incorrect by the left-wing aßholes who control this whole propaganda) and the relevant one is the "delta variant" (yes, it used to be the Indian variant). A few weeks ago, the delta variant was responsible for 90% of new cases in the U.K.; that delta dude dominates the (right end of the) graph of cases. How does it differ from the previous variants? Well, the previous variants often killed people, didn't cause a runny nose, but could cause the loss of taste and smell. Instead, the delta variant doesn't cause the loss of smell and taste. But it does cause the runny nose, sore throat, and reactions similar to seasonal allergies. >The delta variant looks like a cold, swims like a cold, and quacks like a cold. Why is it so?

Magnesium because most soil is shit, potassium because you need an insane amount (4.7 grams) to make up for the diet our ancestors had, who chewed on wild veggies most of the time as they moved through the world to hunt, gather or finding new fishing spots. Are you concerned at all with these electrolytes? If so, what are your prefered choices to get the recommended amounts? Also most of the K and Mg is inside the cells, so avoid the "muh blood work", which tells nothing. 0 images | 10 replies Frustrating Hypothetical All my friends disagree with me on this but I’m sure I’m right: If you go back in time a million or so years and move a single grain of sand in the middle of the Sahara desert a millimeter to the left, leaving this the only thing changed, have you impacted the future (present) in a meaningful way (e.g. a measurable change, human history, state of the earth, etc.) 90% of my friends say “no” and claim I’m taking “the butterfly effect” way too far and nothing would change. Even some people who agree with me are more reserved such as “it may or may not change the future” when I know for a fact it would. Want to hear some other perspectives. Make me believe you if you disagree, if you agree help me better formulate my opinion. -YS 1 images | 10 replies No title ITT: Based scientists. 6 images | 15 replies Redpill me on modern experimental physics How can an academic discipline exist when it pulls the same scam every time: - be professional noise interpreters - make some shit up about what you found in the noise - pretend like its some new exotic particle or dark matter or something else you made up - ask for billions of dollars so you can run a new scam You have to appreciate the scale and the brazenness of the scam. But surely people will catch on eventually right? Are these (((scientists))) worried about being lynched by the taxpayers for fraud? Are they not worried about the mathematicians that call out the fraud daily? How do you get such a large recurring scam going and just run it out in the open? Are they really just that good at bullshitting people? 6 images | 47 replies No title I want to throw a barrel into the sea and to be able to track its movements with a gps.

Given the large body of reported cases by credible witnesses (sometimes with compelling physical evidence such as the Lonnie Zamora case), scientists mostly brush the subject aside. To me this appears very close-minded, and reflects a fear of new information that could challenge a person's fragile worldview. 1 images | 3 replies What made you study STEM?

Jesus Christ I'm such an idiot. I barely read the financial aid offers since I was in the middle of a hectic school year and I skimmed over all sorts of information. I could've fucked around with philosophy/politics at the liberal arts college but I convinced myself that the other one was worth it because of its reputation. I'm losing my mind thinking about this shit. Do you think if I reapply to the liberal arts school next year that they will accept me back with the same offer?

Why has there not been a single mention of vitamin D from our public health experts (NIH, fauci, etc)? We've known how important it is in preventing COVID yet no one bothers to mention it. No mention of getting sunlight or taking a supplement. Same with zinc although D is most important. Really makes you think.

Need a little help - Universe
I am searching for an answer to my wonderings.

If the most powerful telescope we have can see to about 10-15 billion light-years (start by knowing that the supposed age of our Universe is 13.8 billion years) and James Webb will be able to see almost 100 million years after the Big Bang, does that mean that the Obeservable Universe will be almost the full scale of the whole Universe?

Because as i think, we will be able to see almost the beginning of things, which will be nearly the whole Universe, am i right or the Observable will always be a micro-dot of the whole scale?

Air pollution
So i recently started getting concerned about the air quality inside my house, since i just feel like the air outside its alot nicer than inside my house, does air pollution actually kill as much people as the media says? will i die if i dont move to a different house? what do about bad air quality, i vacuum every week, sweep floors, and keep the place i rent decently clean, when i moved in it was somewhat old and beaten up, the carpet flooring inside one of the rooms looks pretty old, should i get some professional to clean it or just move out completely?.
