Why are women in academia so rare? Are women just less intelligent than men?
34 posts and 3 images submitted.
>>
>>8869364
Intelligence is a spectrum and women are on the lower end. After they complete their transition to men, they can become more intelligent.

The fact is that most of the successful women in STEM are men.
>>
>>8869371
That would explain why women want to become men, but why do some men want to become women?

Why is science losing its place in western culture? I mean real science, not pop science infotanment junk. The term STEM was meant to bring more of the educational establishment into understanding the importance of STEM subjects. Instead they keep watering it down. First they added in Art to make STEM into STEAM. Now they're adding in Reading to make STEAM into STREAM.

What, if anything, can be done to fight off this dilution of STEM's importance in the education system?

About to start my master's at same place in applied math.

Love this place, but I feel like the departments are so small I can't choose to study outside what they give. I might not stay here for PhD, even though the applied math dept has already offered me a place.

Anyone know a place with good functional analysis?

What are some safe, well-tested means of boosting brainpower?

There's a lot of bullshit floating around about how to boost IQ, but that's not what I'm interested in. I'm more curious about daily habits that increase the amount of intellectual output a person is capable of. Some questions:

How much caffeine is too much?

What's the best time of day for productivity?

Does exercise really improve mental performance?

Any opinions on sleep cycles, concentration drugs, or mental exercises such as n-back?

Links to studies would be great.

Best amount of caffeine is no caffeine. If you weren't already addicted to it you wouldn't need it.

something along the lines of eating baby blood or umbilical juice or something

If you're over 20, which you should be, it's too late.
You'll be a brainlet forever.

You're not out of it, but fuck man how stunted is your worldview that you would ever think that giving money to your parents like that is okay?

They shot their load and they made you. If they're not having any more kids, they should be putting all free resources into you, not the other way around. It's simple game theory.
>>
OP should have kept the money for them self.
Women will always have free handouts and shelters to stop them from being homeless without having to do shit. Yet a hardworking man that has earned their scholarships is expected to be homeless and fail.
Fuck life.
Anyway as long as OP does really well in GREs they should be able to get into a graduate program and live off being a TA. Theres still hope if you want it.

I was reading that Elon Musk got his BSc degree in physics and right after he started his PhD studies. In USA you need a masters to do a PhD? I am Brazilian, and here the order is bacharel (BSc), mestrado (Ms) and PhD (doutorado). Can someone explain this to me?

Some universities allow you to do both at the same time. You're going straight for a doctorate, but it takes the time for a doctorate + the time for a masters.
>>
>>8870680
What benefit do you get out of completing your PhD directly after a Bachelors? Appart from getting out of uni quicker and into the real world.

To me it just seems silly, like you haven't learnt enough to really contribute anything new... wouldn't it be better to go ahead with a master's first?
>>
>>8870775
It depends on the field. Someone who has a PhD is just as prepared as someone with a PhD and masters, all else, equal, 90% of the time. Masters is like the knowledge component of the PhD, but that is not what shows the mastery of the field, its the thesis crackdown

I don't normally post on this board, but I'm an Econ/Math double major in college that does a lot of investing in his free time. I don't want to get into the economics of this and mostly focus on the science, but I was looking at grain prices (corn, soybeans, wheat) and they've pretty much gone universally down. I don't know much about the technology behind this, but it seems to be the cause of GMOs and similar genetic engineering techniques that have boosted yields.

Now, given that prices are so low, I was wondering if any situations that could boost prices that are science-related had a probability of happening. What i mean by this is, do scientists forecast droughts in the Midwest/Great Plains that would restrict supply or are we steadily approaching a water crisis that can't be solved with desalination?

Additionally, are there more technological advancements to come? I've read about CRISPR and it seems like you can use it to do precise gene-editing in plants (https://ensia.com/voices/crispr-is-coming-to-agriculture-with-big-implications-for-food-farmers-consumers-and-nature/) so I'm under the impression the increased development of CRISPR should be groundbreaking. Is it really groundbreaking for plants or is it not really that big of a deal given that we're already doing GMOs? How much more can CRISPR do than our existing capabilities can?

>the increased development of CRISPR should be groundbreaking
Bear in mind genome editing via CRISPR
has been done only a few years, and only
with a few organisms, and is not heavily
funded for research.

Climate change is a hoax, it's the debunked "global warming" all over again.

I have a weird question about digestion, and I assume biology falls under /sci/ domain. So about 45 minutes ago I ate a grand slam at the Denny's here on campus. Got back to my apartment, stomach pain, and now I'm on the pot finishing up a torrent of liquid shit. Judging by the amount, my body didn't even try to process this stuff, yet of course it's still a poopy brown sludge. So my question is: how long is the digestion process, and how did my body manage to both reject and turn the food into some semblance of poop in such a short amount of time?

That's much too fast for the solid food you've consumed to be coming out the other end. 45 minutes is enough for liquids though. What you've done is consume a liquid (or something that quickly dissolved into a liquid in your stomach), which has softened the shit that was already in your colon.
