botany question - what are the options for cross-hormone supplements? Archived /sci/
I am taking up botany as my retirement "thing" and have some experiments I want to try. before I do them, I want to find literature on previous work and I simply do not have the background to know how to phrase what I want to do. I have these ideas I want to try these:

1- kudzu has overtaken a large section of my neighborhood. I have an idea to harvest the growth hormones from it to feed my vining plants, such as mulberries, strawberries, and grapes. my rationale is how rooting hormone is either synthetic or extracted from a plant with a high root growth habit, though I am familiar with other approaches like capsacin. would harvesting and juicing those leaves in the morning to maximize yield make any noticable difference, as in, is this a common practice to cross hormones between plants for some advantage?

2- I want to grow some large amount of basil (for example), and harvest the leaves for their growth hormones in a grow room environment in a more or less hydroponic/kratky setup. I can reliably induce the temperature and light patterns to induce hormone production on the leaves, which I would then harvest, juice, extract, and then feed to a batch of other basil plants in a sort of cannibal farm for plants.

3- forcing lignification. from what I read about it, there appears to be some simple hormonal pathway to induce it, though I cannot locate literature as to how.

I think you can gather what I intend to do here. I suspect that it is possible to harvest the hormones responsible for the higher growth rate of something like kudzu, and feed it to a genetically similar plant. I am also interested in extracting saps/sugars/chlorophyll from donor plants to feed to experiment plants. what is this overall practice called, the efficacy of it, and if possible, some literature I can study on it?

TIA.

normally i like to make up silly stories and larp as insane racists when i'm on 4chan, but this time i'm serious. autism researchers seriously need to look into the physiological effects of intoeing in certain subgroups of autists.

my hypothesis is that intoeing (inward rotation of the legs, which makes the toes point inward) can reduce certain fine and gross motor deficits in autism. other things need to be looked at like eye contact. my hypothesis is that eye contact, when measured in seconds of in-person conversation, will be positively correlated with the use of intoeing in either a standing or seated position.

other possible things to look for are:

(i'm just gonna copy and paste what i found.)

>Primary outcomes (mechanistic + high signal)

>Breathing mechanics

>Diaphragmatic excursion (mm): M-mode ultrasound during quiet/forced breathing.

>Thoracoabdominal contribution (% ribcage vs abdomen): optoelectronic plethysmography (OEP) or respiratory inductance plethysmography (RIP).

>Chest wall kinematics: 3D motion capture/OEP of pump-handle (AP) and bucket-handle (ML) rib motions.

>Spirometry: VC, FVC, FEV1, FEV1/FVC, inspiratory capacity at fixed postures.

Is modern science just a convoluted game of "Finders Keepers"?

I would like to propose that we stonewall all scientific awards related to any data that is withheld from an entire discipline for 30 days or more.
It does not matter what is in the HiRise data, this is too long. There will be NO Nobel for ANY finding in that data. The harm of withholding it from the rest of the astronomers on the planet, reduces the discovery impact potential.

Quick, justify the withholding of the HiRise imagery.
Hard mode, do not blame any of the following, as these reasons have NOTHING to do with the advancement of science or the scientific method, from a social human perspective:

1. Politics.
2. Money.
3. Ego.

I think everybody in this board knows math is pretty awesome. So, I thought I would dedicate the many hours of free time I have to learning math through textbooks.

This is my current reading list:

- AoPS Introduction to Algebra
- AoPS Introduction to Geometry
- AoPS Intermediate Algebra
- AoPS Precalculus
- AoPS Calculus
- Spivak – Calculus
- Axler – Linear Algebra Done Right
- Hubbard & Hubbard – Vector Calculus, Linear Algebra, and Differential Forms
- Arnold – Ordinary Differential Equations
- Bertsekas & Tsitsiklis – Introduction to Probability
- Wasserman – All of Statistics

Is this good enough until I want to move into something specific?

So, I see a lot of people complaining online about electronic harassment.

Obviously, that's just a common psychiatric symptom, although with some of the patents in the books, there is clearly the physics potential for electronic harassment to be real.

I could even electronically harass people for a few hundred dollars...

As Scientists, how do we address these overlaps between insane people's delusions and rare actual events of criminal conspiracy and illegal black budget operations?

Too many, well meaning, highly intelligent "Scientists" just close off their mind to complicated things that seem crazy, but imagine how limiting that perspective really is.

There are actually professionals who have to think about this stuff for national security, but yet, 100% of the people claiming to be electronically harassed are simply disregarded as crazy. Think about it. Some of them really could be telling the truth.

The phenomenon looks genetic except that it violates Mendelian genetics because the kids are almost always 1st born. If you have ever been put in the gifted category you need to read this book.

What is the interpreter? There has to be _something_ that interprets something else, information by itself is static, it does not do or mean anything, it can contain an interpreter in any form but such interpreter would be static too. Therefore I conclude a duality: reality consists of an interpreter acting on raw information. What is the interpreter?

Hi everybody im new to maths and am starting from elementary principles to build a strong foundation and am reading "Rational Numbers to Linear Equations" by Hung Hsi Wu yet cant wrap my head around this proof. Not only does he not exhaustively prove all cases for x and y, but he seems to just arbitrarily mess with one side of the equation and not the other to get it to do the thing he wants it to do.

e.g.

Case 1: If x,y > 0, then we resort to this theorem to prove that there exists a rational number z such that x =zy.

"Theorem 1.8. Given fractions A and B (B is nonzero), there is a unique fraction C, so that A = CB"

Now, if x is negative and y is positive, then Wu tries to rewrite the equation to conform with case 1, which will, by Theorem 1.8, give him a "z". Therefore, he says that if x < 0, then -x > 0. Then

(***) -x = z'y

Multiply both sides by -1

x = -z'y

Viola! z = -z'

However, I don't understand why Wu arbitrarily flips only the x and not the y in the step denoted by (***) above. That, among other things, confuses me.
