So why does /sci/ hate philosophy and philosophers so much?
29 posts and 5 images submitted.
>>
>>7724518
It doesn't. We routinely have threads on the philosophy of science.

If you're hurt that people tell you to fuck off, maybe what you're putting forward isn't philosophy, but senseless babble.

It's like when people tell popscientists babbling about quantum magic to fuck off. It's not that they hate science and scientists so much, they hate meaningless drivel.

like 95% of philosophy majors are pre-law(read: useless) and therefore not /sci/ related in any way. nobody even talks about it. good luck finding a philosophy major that is also a maths double major or something.

What is a good book on optimization? Especially computational optimization techniques.

I believe Knuth has a section somewhere in TAOCP.
>>
Recommending: Wooldridge's Introductory Econometrics. It's a good starter book for anyone who has a little bit of stats experience. For an introductory book, it's very broad, and should be useful for someone looking for a good self study book. Covers time series as will.

Request: Just finished a calculus based introductory probability and statistics class. Where do I go from here if I want to delve deeper into probability?

This is a bit of a neuroscience question. It bothers me because it's something that has just resumed happening. And it's irritating. If I'm dealing with an uncomfortable situation, strangers, or something I find unnerving, If I attempt to make eye contact or move my head towards someone my neck does this stuttering thing. Like my mind is shutting down, or having some pulse-like seizure deal at the mere idea of making eye contact. Otherwise I feel fine, can converse properly, but there's like a radius. And if I move my eyes within that radius of someone's face, it happens.

Factors to bear in mind:
-Food allergies. Ate some shit recently and this has probably resulted in the elevation of histamine.
-Caffeine consumption.
-Ate a lot of cocoa beans (salsolinol, endocannabinoid reuptake inhibitors, flavan-3-ols etc)

The latter two tested independently do not result in the above, nor do they when together. That leaves the first. Unfortunately I don't know much about IgG, IgA, or IgE reactions, nor the full extent of histamine and inflammatory processes ability to act as modulatory neurotransmitters etc.

Please help me downregulate this lust to understand.

It has to be the coconut I ate. It's as though it reopened the gates, and I'm back in a land of strange anxieties I falsely believed I had gotten rid of, worked passed, understood and reconciled, whatever. It's all an illusion. A machine easily mistakes its own operation to be more the result of intrinsic factors than it really is.

Fucked for life. So I just need to understand.

I don't think there exists a true self, but some selves are more you than others in a given context. I try.

I feel only partly conscious. Wired, fully aware, stressed, calm, and part asleep. How can this be? Any recommended reading material? I mean truly good textbooks on neuro-anatomy, neurology, neurochemistry. Etc. Something that wants to act as the proxy to tell the reader everything there is to be heard. Any other teaching style and I will find myself fighting the author.

>When methylene blue was tested in healthy cells that were allowed to progress at the normal rate, the chemical also repaired the age-related damages. The findings were published in the Aging Cell journal on Dec. 10.

How should I start applying methylene blue to age less? Should I apply it on the scalp to prevent balding? Should I just smear it all over myself?

yipe. that's difficult. You mean

do you mean y(sin t) as in function y of sin t, or y times sin t?

Question regarding the philosophy of science.

Is the scientific method in use today "optimal"? How much of it is arbitrary compromises with practicality?

How much of it will change 100 years from now? 200?

What kind of scientific method would an advance extraterrastrial civilization have and how much would it differ from ours and in what ways?

Is there any piece of evidence at all, that can point towards genetically modifying organisms as something negative? I've seen the arguments for GMO's, and I completely agree with them. Let's have a circle-jerk about GMO's.

What's the big deal with GMO warnings and bans?
24 posts and 1 images submitted.
>>
>>7724644
There's no evidence that they're bad for health, and I don't really care if they are or not, but they certainly make monopolies in farming much simpler, and since companies like Dupont and Monsanto get huge government subsidies anyway, that's a pretty bad thing.

Basically GMOs allow companies to patent the genetic code of a given seed and extort third world farmers into buying their seeds again and again, by first selling them seeds on loan, and then forcing them into deeper and deeper debt because the GMO seeds are the only ones that have large enough yields to make significant headway in paying off the earlier debts.

Also, AFAIK, the only thing people are agitating for is labelling, which no one should be opposed to. A label like the one you posted could negatively impact sales because of its coded design, but a more neutral label will serve only to inform people about a pertinent aspect of the product they're buying. Dunno why you'd be opposed to that, besides just for the sake of being a contrarian.
>>
Probably the worst thing is a continuation of what already occurs. Reduction of genetic diversity. There are also issues of GMO crops mixing with "organic" crops and this potentially ruining farmers who do not use GMO crops by forcing them to destroy their harvest.
>>
>>7724662
Organic is a scam
