Underrated universities.

I'll start with the National Technical University of Athens. It might not be one of the best universities in the world, but the engineering program is pretty solid. Certainly a Top 100 (in this department - engineering).

Do you have any "hidden gems" in your country?

Not arguing morality of being gay.

Is there really any solid basis in homosexuality being a result of one's DNA? It doesn't make any fucking sense of why being gay would have any evolutionary advantages for a species.

it's definitely hereditary.

more than 90% of straight-straight offspring comes out straight
more than 90% of gay-gay offspring comes out gay,

so with facts like that it's basically impossible to argue that it doesn't have a genetic basis

Does it depress anyone else that unless you're hawking level, any contributions you make to science will largely be insignificant.

>>8650848
>contributions
Wrong. You can contribute in multiple ways even if you are not mastermind. In fact, anything you do in """"science""" (what the fuck does that word mean outside the schooling system?) helps grand-master scientists like Hawking and others do their work.

Examples
1. Hawking is studying black holes. He needs 10 scientists to help him. Each of those scientists need 10 scientists to help them. Each of those need 10 laboratory-workers/technicians/programmers/whatever to help them. So just be someone in this value chain; help better minds achieve their goals.

2. Society has priorities of food over black holes. If lesser scientists didn't occupy these positions, Hawking could never study such abstract and useless concepts such as black holes; he would probably be employed in studying fuels or fertilizers.

These are not notes of the Weak force, they are noted on the Standard Model. The weak force does not involve quarks, gluons, and their composites.

FDA is overreaching and is seeking to classify anything genetically altered as a "drug". For instance if a breeder uses crispr to fix genetic defects in a breed, they will have to go through FDA and the animals created will be considered drugs.

Comment to the FDA
https://www.regulations.gov/document?D=FDA-2008-D-0394-0279

the altered genomic DNA in an animal is a drug within the meaning of section 201(g) of the FD&C Act because such altered DNA is an article intended to affect the structure or function of the body of the animal, and, in some cases, intended for use in the diagnosis, cure, mitigation, treat ment, or prevention of disease in the animal

Damn. That sucks balls. I hate stupid people who don't know what they are talking about and are terrified of GMOs.

What about crops? Aren't almost all crops genetically modified to some extent? Or does have to be modified in a certain way? I am especially thinking of corn.

but OP, I fully support GMOs being heavily regulated if not banned, I'm going to submit my comment in support.

How hard would it be to increase the speed of neurons? The biggest problem of AI - Human competition is that humans think about 1,000,000 times slower than a similar computer due to the slow speed of biological neuron actions.

Is it possible to get massive speedups in terms of neuron speeds by "hacking" the brain with some smaller machinery that increased these speeds?

Action potentials jump between the myelin sheaths so maybe those can be lengthened

The myelin sheath is what acts as an insulator (sort of like rubber around electrical wires). So, making sure that you had good nutrition to have healthy sheaths would keep electrical charge in.

The big problem is the synaptic cleft. Even though there are electrical charges that propagate down the axon, ultimately, the communication between neurons is chemical. A vesicle has to release neurotransmitters. I can't think of a way to speed that process up.

An even bigger problem is that you can get low on neurotransmitters. So that might be another hack. Making sure that your neurons have plenty of nutrition to produce as much neurotransmitters as they need.

Finally, the whole process uses up a ton of ATP. ATP requires water and sugars to be produced. So, maybe a last hack would be to make sure you have plenty of energy. Eat pasta/sugar and drink water when gearing up for an exam or something brain intensive.

Neurons are slow compared to circuits yes, but the human brain is massively parallelized which is why the computation is much stronger.
