'sup /sci/. The new Planetarian adaptation made me wonder something--how hard it is to find a planetarium that actually uses its star projector these days? Every one I've been to just shows an iMax movie on the dome, even if they have a brand new star projector like the Hayden in New York.
Do I have to look for particular shows or what? This is getting impossible.

Hi /sci/, from some time, I'm into fusion cuisine (or molecular gastronomy), (Answer to questions: my post is more into chemistry than normal cooking), and I saw how to do a apple juice foam (add lecitin and whip it), and my question is: what chemistry (or physics) let to make foam? I heard that lecitins help making emulsions, does it have something to it? What use instead for lecitins?
>>8233049
egg whites
>>8233049
Also if you really give a shit about know why things foam or emulsify, go on wikipedia for the articles "Emulsion" and "Foam". No reason to get us to do your shit for you.
>>8233069
Yes, but some no flavor change. Have idea?
My semen demon (she's studying literature) sent me this
Is she right? I already passed my obligatory courses on physics, so I could theoretically forget about it
Maybe we could change that though with physics and new technology. We're all here for either the sake of our knowledge or to impact the earth positively, if you won't do it then no doubt someone else will make a contribution.

Hey /sci/, I'm really interested in the branching patterns of plants and I have a weird question.
Has any research ever been done on the topic of how branching patterns are "coded" for in plant genetics. There's so many interesting patterns and I would really like to read more on how the plants "know" to grow branches like this.
I mean, obviously it's to maximize sunlight for the leaves and have flowers in advantageous positions but what makes an oak grow branches in a different pattern than a pine tree?
I really want to learn more about this.
That's a good question Anon.
There are many examples of things like this in nature that really should be looked into.
On a similar note I've always wondered how the brain is initially formatted - i.e. turns from a bundle of new cells into one of the most highly specialised computers in existance?
>>8231680
Yeah I think that question is in the same vein. Like what genetic/hormonal mechanism tells a plant cell it should start diving in a different direction to form a branch or what mechanism tells a neuron that it should be concerned with a certain type of stimulus.
I've always been reallt interested in how plants seem to mimic fractals. Like if you look at how the first branches come off of a stem and then look at how sub branches come off of other branches it's obviously the same pattern being repeated.
I'd love to know how a plant determines what fractal growth pattern it will use and when to stop making sub branches.
>>8231693
Ah well general growth patterns like that are mainly to maximise light-gathering potential for the smallest amount of growth, that boils down to mathematics.
Methinks plants behave a bit like a cellular automaton, cells will grow in certain directions based on some in-built rules. The patterns formed in their growth will be a result of these rules.

So I have here the solutions to the first three problems in spivak's calculus 4th edition.
I need you to tell me if I'm retarded.
>I.) if ax = a and a != 0, prove x = 1
a(x^(-1)x) = 1a = a
x = 1
>II.) prove x^2 - y^2 = (x - y)(x + y)
(x - y)(x + y) = x(x + y) - y(x + y) = x^2 + xy - yx + y^2 = x^2 + 0 - y^2 = x^2 - y^2
>III.) if x^2 = y^2, prove x = y or x = -y
x^2 - y^2 = (x - y)(x + y) = (x + y)(x - y) = 0
x = +-y
I feel like III is most definitely wrong.
>>8229999
>I feel like III is most definitely wrong.
Why? It's correct, which you can
verify by substitution of your results
into the original equation.
Maybe the property you're unsure of is that there's no zero dividers for real numbers. This translates to the fact that if for all real a:
a*b=0
then b=0. Consider fixing x in your expression. The edge case is y=0, in which case x^2=0 or x=0 and so x=0=y=-y satisfies the claim. Now, safely assume y is not zero. Then x-y != x+y. You have two possibilities for your expression to hold, either x-y = 0 or x+y=0. Then it must be that x=y or x=-y for all values.
Nice quads btw>>8229999
1) is wrong because you don't know a priori that x is invertible, but since a is by assumption you can multiply rhs and lhs by a^{-1} to get the result.
2 and 3 are fine, maybe you want to add written explanations of why you are allowed to do each step?
Alright /sci/ is it possible to create a THC breathalyzer? If so, how?
>inb4 DUDE WEED
>>8229831
Does anybody know?
Almost certainly not. For one, unlike alcohol, THC isn't volatile.
I was actually wondering about this myself.
In order to test for recent exposure, such as what we would care about for dwi and the like it would have to be near real time which rules out other bodily functions such as urine tests
But thc can be injested as well as smoked, and you can't necessarily rely on the presence of other compounds if the thc has been purified
Breath alcohol also relies on a simple test, whereas detecting low levels of thc or related compounds may require more expensive equipment and police training, say a mass spec or similar
All in all I think it may be most efficient to swab the hands of suspects and send it to a lab for testing

I've been using piracetam for about two months. It gives a nice sense of weight to my thoughts and concentration. It's not obsessive focus, but substantial.
Smoking is obviously a terrible idea, but nicotine really does seem to be worth trying.
It was as much a thinking man's staple as caffeine, back before people knew what carcinogens were. I'm thinking of buying some patches.

A : Consciousness is a byproduct of the electrical feedback in a neural net and completely a materialistic concept ; Which means an AI when gets sophisticated enough, is conscious.
B : Consciousness is a spiritual concept and exclusively found in humans / animals ; Therefore an AI or anything synthetic will never have consciousness
C : Consciousness is an illusion as in the viewer (you) are the god, the observer and everything there is and everything else is (you)r imagination : Means that no consciousness is truly real.
