How good is the scientific understanding of nutrition?
Does there exist a definitive guide to what one should eat? Maybe even some food plans that make sure you get all the nutrients?
It seems like everyone has a different opinion. Some say eat this. Others say avoid this. Some say it worked for them. Some cite scientific research. Others say that research is not credible. With some it's not sure if they just want to sell you stuff. It's a cycle.
Do we really know so little of nutrition? Or does it differ greatly from person to person?
I've never met a nutrition major that wasn't some chakra poking brainlet.

Yes

Yes
Nutritional science is hard. The miscibility of foods is poorly understood.
The field is also full of industry shills publishing data in shit tier journals that are favorable to their specific industry
The calorie counts of foods are all wrong and the gylcemic index is bullshit

Hahahaha no. Analytical chemistry barely produces any good research. Oh wow we detected incredibly small amounts of heavy metals in fish, it's so small it's nothing to worry about, but we did it. Literally an Anal. Chem paper. Most Anal. Chem research is just done to keep the field alive and train grads, it's just like why people still analyze shakespeare's work even though they've done so for like 200 years.
You'll never make cool molecules like pic related.

He's a good lecturer. I recommend his intro algorithms course that's online. He co-teaches.
The guy who runs Tarsnap (cpercival) has the same CV, started Bachelors at age 13 http://www.sfu.ca/archive-sfunews/sfnews/2001/June14/percival.html
Don Knuth has a similar CV, so does Daniel Bernstein
These people aren't super geniuses they are just motivated. If they were geniuses they'd have solved some of the math millennial problems or found new breakthroughs instead of just being professors (exception to Dan Bernstein, legit genius).
Why is technology not yet at the point of getting corpses off Everest? I thought Sikorsky invented a high altitude helicopter?

It's a money thing. Not a lot of money in recovering Everest corpses.

Why ain't we all running for cure against getting old and die?! We kill ourselves everyday by not watching for it, several times a day, by hitting our bodies in corners, by being exposed to sun, dust, microbia, all the unrest there is. Even tight socks may be harmful. Even keeping the urine when it wants out. So we need to eliminate those factors. Our body rebuilds itself, yes, but the fact that we die in about 100 years tells us that it doesn't support our way of life good enough. It can replace gone cells only by splitting other cells, but there's Hayflick limit...

So it's many layers of this decission:
first we put ourselves in spheric baths (ph should be regulated, temperature should be regulated, air and water supply should be regulated:
we regulate ph by piss and pure water (if somehow there would be not enough of salt or other components - we should add those too) and constant control of salt in the water.
then we attempt to grow ourselves placentas (cloning ourself a clone instead of children and making the clone's placenta split on early stages would require machine to replace the missing flow. so it's better...

Or maybe those kids working with telomerase would succeed but they might need to remove ribs and skull to let the flesh grow the way it likes. And they would still need those bathes because mere statistics shows hell is round the corner, so even if we die at least don't let us rot, it might be painful.

Why you can't divide by zero? I you for example divide 10 by nothing you get 10.
Why you can't do it? Because it hits "the queen of all sciences" right in the face and shows it's not so perfect and not so pure?

>>8082771
Because [math]0[/math] has no inverse.
When you "divide" a number in a field such as the reals, what you're actually doing is multiplying by its inverse.
e.g. [math]\frac{1}{2}[/math] is actually [math]1 \cdot 2^{-1} [/math].
Recall from abstract algebra that the inverse of [math]x \in \mathbb{F} [/math] is an element [math]y \in \mathbb{F}[/math] such that [math]xy=yx=1_{\mathbb{F}}[/math], where [math]1_{\mathbb{F}}[/math] is the multiplicative identity.
There are however algebras where...

So I found out today my half brother does not believe the earth is round. Does anyone have any fun experiments I can do to show this?
My first thought was buying a telescope to look at the ISS... since he also dismissed the idea of satellites to be hoaxes... *rolls eyes*
The reason I'd like to do some experiments is that I conceded early on that I hadn't performed any of my own experiments and am more than happy to accept evidence provided by other people, images of the earth and how people propose the GPS works. Saying all of these people are lying with...

Ask him how GPS works, or why there are crescent moon phases.
>>8092102
I mentioned GPS to him. He said that he believes they are radio towers made to mimic satellites... I said GPS works in any location on the earth, even in the middle of the ocean with no towers visible... he essentially rejected that to be true and that I've never been out to see to confirm that.
>>8092116
have you? Can you blame him? If you're truly skeptical, you would only believe what you can see with your own eyes.
The earth is a 2D manifold locally. Therefore by integration, it's a flat surface. Wherever you go, the earth is flat just the same.

Are Thorium / molten salt reactors over hyped and unrealistic? or is it really the best alternative we have to the current energy climate?

Overhyped. Completely possible, but not a significant enough of an improvement over current fission technology to care about when we are well on our way to fusion already.

Hey /sci/,
I'm posting this thread because there's been a "smoking isn't bad for you the government is lying" meme going around on this board for some ridiculous reason.
Here are some peer reviewed articles for all you smoking "truthers" out there
Dangers of smoking

>all smokers

this implies that the "all smokers" group includes those who have had one cigarette in their lifetime. sounds like some heavy averaging.
>>8086764
He's saying there are people who actually lie or have bad intent when conducting studies or analyzing results.
He actually doesn't deny that smoking is bad for you (he says nothing about that, to be more precise), but he doesn't like the way it has been forced down everyone's throats.
>this implies that the "all smokers" group includes those who have had one cigarette in their lifetime. sounds like some heavy averaging.

Drinking alcohol, even in moderate amounts, LITERALLY shrinks your brain.
Why do you still drink, /sci/?

Is it a professor's job to teach or to simply present the information?
to collect a salary and complain that it isn't enough of a reward for all your noble sacrifices
>>8089747
from my experience apparently their job is to read out loud the lectures summary word for word
Their job is to come in to work 30 hours a week, hang out in their office with their dogs, maybe read a manuscript or two, then write their name in as a prominent author on every article their underlings write for publication.
