I have found nicotine to be an awesome nootropic. Two times a day administrativing 2mg via throat lozenge (best englisch word I could find for what I mean) is awesome for studying.

But I have a question for the biochemists/meds

How would you rate nicotines adverse effects? Especially inhibition of tumor suppressor mechanisms and clot formation?

DNA confirmed for determinant variable in IQ development: http://www.nature.com/mp/journal/vaop/ncurrent/full/mp2016107a.html

>Results show that DNA can be used to predict educational achievement, especially at the end of the compulsory school years. We found that the 2016 EduYears GPS accounted for 9% of the variance in educational achievement at age 16, tripling the effect size from previous reports based on the 2013 EduYears GPS. The predictive power of EduYears GPS can be seen especially at the extremes of the distribution of GPS scores, suggesting that it is possible to identify individuals early in life at genetic risk and resilience, moving us closer to the possibility of early intervention and personalized learning.

>We have previously reported a heritability estimate of 60% for educational achievement at age 16 using a sample from which the present sample was drawn. The present study demonstrated that EduYears GPS predicts 9% of the total variance in educational achievement, thus accounting for only 15% of the heritability estimated by the twin design. However, unlike twin study estimates of heritability, GPS is derived from GWA studies, which are limited to additive effects of the common variants employed on SNP arrays. For this reason, SNP-based estimates of heritability, which have these same limitations, represent the current upper limit for GPS prediction. For educational achievement, SNP-based estimates of heritability are about 30%, and EduYears GPS explains almost one-third of the heritable variance from SNP-based studies at age 16.

>We believe that the substantial increase in heritability explained by the 2016 EduYears GPS represents a turning point in the social and behavioral sciences because it makes it possible to predict educational achievement for individuals directly from their DNA.

Does this mean that in the future, children could be genetically engineered to grow more intelligent?

So about a year or two, I decided to start researching what could affect IQ and overall mental performance. I asked about it here, and of course, got shit for it. But some people were interested, so I figured I'd share the results of my research. Prepare to be disappointed.

>Avoiding nicotine and carbon monoxide emissions can improve your IQ by approx. 5%
>avoiding consumption of alcohol can improve your IQ by up to 7%
>a well-balanced diet which includes little to no foods which are associated with cholesterol and processed/refined sugars can improve your IQ by up to 5%
>a regular/daily light exercise routine which includes training for flexibility and cardio improves blood flow, improving IQ by up to 10%
>if you're a large individual, reducing your BMI count to between 18 and 24 can improve your IQ by up to 11% (both fat and muscle mass are detrimental. Your size is more important than your weight, as it has to do with the amount of blood vessels you have, and how many are used to send fresh blood to your skin)
>7 hours of sleep, no more no less, improves IQ or retention thereof by up to 15%
>reduction of stress levels, or cortisol, improves IQ by up to 12%
>listening to certain music, such as Bach and Mozart, can improve your IQ by up to 9%
>exposure to the colour BLUE can increase your IQ by up to 2%
>avoiding watching TV or YouTube or any other form of digital video media can improve your IQ by up to 13%
>studying or learning something new on a daily basis at a minimum of 1 hour a day, even if it's something trivial, can improve your IQ by up to 20%
>meditation, in order to rest the body and mind, for at least 1 hour a day can improve IQ by up to 8%
>avoiding 'busy' environments, such as cities or pictures with a lot of small details, can improve IQ BY up to 11%

There are a lot more of these. There are formal studies and test results around all of these. Effectively, your body wants you to be one of those pretentious rich yoga fuckers with bad taste in art.

Are Humans that reject science, math and reason still technically "People" in the modern philosophical sense when it comes to Ethics?
I have a hard time empathizing with Humans that reject math, science and reason because it's hard for me to picture that they would have a functioning brain that would even comprehend the intellectual and emotional suffering that self-aware members of the species do.

Do happy-idiots feel pain or care about consequences as much as intelligent People do?
Do happy-idiot Humans pass the test for Personhood if they reject consequences, responsibility and accountability?

The only conclusion I can reach is that they lack the ability to feel deep emotional pain and are not fettered by incorrectness, tragedy, oppression, etc.

They may bleed when picked, they do not feel loss nor seek self preservation (at least long term self preservation).

Pic unrelated.

Would a society of smaller people be more successful? They would have the same body as a person and the same intelligence, just in a body probably around 3 feet tall. They'd need much less calories to sustain themselves making them resistant to famine, and they would be able to have much more babies and a higher population. If they were ever in a war with normal sized people, they would have an advantage with ranged weapons like bow and arrows because they're much smaller so they're harder to spot and 6 foot tall people are so much easier to see and shoot.

Though they would be weaker and have a smaller stride length and be more sensitive to cold... But would the advantages outweigh the drawbacks?

What's the most comprehensive, industry-standard textbook on single and multi-variable calculus?

Here's the deal. I'm a 31-year-old lawyer by trade, but my lifelong interests include physics, compsci, and sysadmin stuff. I probably spend 5-7 hours a week in independent study.

I read Griffiths' Electrodynamics last year, and this year I'm working through the Feynman Lectures. Unfortunately, I'm pretty rusty at calculus, which is the main reason I'm now struggling -- I just don't see how Feynman solves some of his equations.

Money is no object, and I can handle difficult material (as long as it starts from ground zero, I can handle a fast pace). I used to be pretty good at calc, and got good grades in college. I've forgotten much of it over the decades, but much of this still won't be totally new to me. I still know basic integrals, Green's Theorem, Stokes' Theorem, etc., but I'm rusty as fuck.

Any recommendations? I'm a textual learner, so lectures and videos won't do much for me.

I am thinking about writing a story set in a system with several habitable solar systems in orbit of a not too massive black hole, would such a thing be possible without affecting human life inhabiting several planets? Can technology circumvent several issues from this setting?
