Lactose is a B-1,4 disaccharide. Many people lack the lactase enzyme to break it down into glucose and galctose, and are therefore lactose intolerant. To address this, there exist tablets containing the enzyme that can be taken after ingesting lactose/foods containing it. It breaks down normally and all is well.
Cellulose is a long B-1,4 polysaccharide. No human produces the enzymes to break it down to useable sugars. Why not create a gel-coated tablet that passes through the stomach and allows humans to digest it?
If we could digest cellulose, nearly any soft vegetation would be a source of nutrients. I'm sure I'm being retarded somehow, but what am I missing?

So poor people could eat grass? Would the production of the enzyme be cost effective? Grain already is cheap.
It's not as simple as that, lactose is a tiny molecule by comparison to cellulose; 2 sugar units compared to several hundred.
Breaking down cellulose into individual monomers is a pain in the arse of a process, under body temperature conditions it takes quite a long time to fully digest.
This is why cows have multi-chambered stomachs and rabbits eat their own shit.
Even if you did consume the right enzymes, your intestines would get clogged with hardly-digested plant matter very quickly.

So you're saying it would work if you would also eat your own shit?

Average medical is 115 so you don't need to work as hard as the others.

Ok so I have looked heavily in liquid fluoride thorium ractors and i have yet really to see a down side. can someone here point out something my overly hopeful mind is glossing over?
also why the fuck arent we making these yet?!

i cant answer your question but maybe you can answer mine.

Embarrassing uni stories thread?
Today I went to one of a lecturer's office in the cs dept that I've never seen in my life but passed his class. Unfortunately I forgot to register it in this year's classes so I had to sort things out with him. I knew his name so in the cs dept I asked a young guy outside some offices whether he knew where Mr X was. He was in front of me. That ought to be my most embarrassing uni story.
>>8771611
that's all?
one time i spoke with a lecturer and when i got up from my chair i noticed i left a huge ass sweat mark on it, i looked at it for half a second and I must've had a surprised look on my face something like "oh, wow, interesting" because the lecturer then immediately looked at what I was looking and noticed the ass sweat too. He stared at it for a fraction of a second but had a look on his face that expressed disgust and contempt.
>>8771611
I always leave ass sweats on chairs and people notice all the time
i like to think that they analyze me and try to mentally insult me and critique me. I bet they're all like "man living life as an autist must be hard, that guy is laughable, leaving ass sweats everywhere, he is full of anxiety and depression, his ass sweats will be the only thing left of him in this world after he dies. A truly pathetic autist, he has no future."
a few weeks ago I was so fucking tired that I really had to take a stimulant, I had to have some coffee but fuck paying 1.2 pounds for a shitty espresso from Nero, I went to the supermarket and bought a small bag of Lavazza, for 3.75 pounds, the best shit there is, and I went to a uni bathroom and just ate some coffee
eating it makes you absorb 100% of its caffeine
other methods of preparing coffee are not as efficient
Why don't more fields work towards organizing all of their knowledge into a tree of categories and concepts? Literally this is the best way (for me at least) to learn everything. It's all scattered throughout random incomplete textbooks, scientific papers, things like this.
I want a tree of all categories and sub-categories of related concepts, from high level down to very low level, for things like all topics. Such as math, CS, physics, EE, things like this. But I can't find them. Has nobody made any of these? You can find some for little things but they're never complete
Can knowledge just not be arranged like this or is humanity lazy?
Someone should calculate one based on wikipedia references or something, but even that isn't good since articles and sections aren't organized very well. Idk
it is called a table of contents to a book
>>8770765
Yes but I'm talking about one for all of human knowledge that you can zoom in on like Google Earth
>Can knowledge just not be arranged like this
This.
Any tree of knowledge can be formally encoded into ZFC set theory (with sets as nodes and membership as arrows), and as with any formal system, set theory is known to be incomplete qua Godel (and Tarski).

>Is showering daily bad for your health?
The question should be: is stripping grease and bacteria from your skin with aggressive chemicals good for your health?
I try not to use shampoo often.
I do not use antiperspirants.
I carefully wash my armpits with hand soap though.
I don't use shaving foam, I shave after a shower.
I don't stink and I don't look dirty.
>>8768277
Why do we shower? Why do people say to shower everyday? Why do you use soap to wash your body? Why do you use shampoo?
Is shampoo and soap necessary?
>Einstein showed that gravity was not actually a force but merely a result of curvature in spacetime caused by objects with mass
