Video game related. In Path of Exile the video game there are many types of currency. I am trying to figure out how to calculate mathematically the most profitable way to trade, can you help?

If i trade you 10 circles for 1 square, and then i trade 1 square for 11 circles (making more circles than i started with) how would i calculate this?

What then, if i had a triangle and wanted to see if i traded circles; for squares; for triangles; and then back to circles. How can i see if i would have more circles then?
>>
Would it be (circles/squares)*(squares/circles)? I don't know about adding triangles
>>
>>10485905
If the ratio of squares to circles is [math]a[/math], triangles to squares [math]b[/math], and circles to triangles [math]c[/math], then your exchange ratio of circles to circles using this loop is [math]abc[/math].

Economics has a lot fleshed out theory for these kinds of things, but most of the framework only considers systems that have no arbitrage, that is, [math]abc=1[/math].
If there is no arbitrage, you can quite easily solve for the optimal assets portfolio, given that you know the prices tomorrow.
>>
OP here still confused, but thank you for the help i will take it into consideration when i know what you're talking about.

Heres where im stuck. I'm going to call the currency its proper name but shortened to the first 4 letters. Feel free to use shapes and or longer txt.

if exal=90
chao=1, the most used currency
chro=.05 of a chao
regr=.25 of chao
fusi=.5 of a chao
what ways can i find out how to trade these items to make money. I'm tring to make a excel spreadsheet to share with others, so if you can provide an example i would appreciate that. Thanks!
>>
>>10486029
This information is not sufficient to make any profits.

For arbitrage, you need to also know things like the exchange rate of regr to fusi without trading them for chao inbetween.
For the investment strategy, you need to guess whether exals are worth more or less chaos tomorrow and buy accordingly. It's probably easier to do with items (headhunter or whatever) though, since currencies are really stable.
For the straw millionnaire strategy, you just take advantage of those who are selling cheaper than the values you just listed.

Neither did I.

>All I have to do is point out that I never once said anything about "material explanation" and we can see clearly that you're attacking a straw man...
What's the relevant difference between identifying material phenomena and material explanation? How can it be a strawman when they are the same thing? Do I need to give you the dictionary definition of identical?

>Is what it is like to be the subject, for the subject identical to material phenomena yes or no?
Yes, specific material phenomena you don't possess simply by identifying them.

>Yes, open a dictionary and look up what the word "identical" means.
Identifying the President is not identical to being the President. Please explain how the definition of identical disproves this?

>Holy shit you're literally retarded... You are so confused beyond belief... Try to keep up: I'm only talking about establishing what something is.
And as I've said 1000 times, identifying what something is is not the same as possessing it. In order to have an experience you must possess the material phenomena, not identify it.

>You need to be careful when you talk like this because there are non-reductive materialists who hold consciousness to be dependent on the physical brain yet they do not reduce consciousness itself to a physical phenomena.
I literally said "according to reductive materialism" in the line you quoted from.
>>
>>10485933
>Because there's no difference in the way we know about them.
The difference is between knowing them and experiencing them. Reductive materialism says they are different because the latter requires a unique brain.

>Then there's no asymmetry between knowing your neurons and my neurons.
I never said there was.

China is using technology to create a clone-army of police dogs. Police dogs require many years of training and training is not always successful. China is working on creating clones of a specially selected genius police dog that will reduce training times by years.

The specially selected dog's clone is currently undergoing training and testing as part of the "Super-Dog" program. The experts expect the clones to also be award-winning geniuses like the original dog.

If the procedure is done correct clones won't have health issues. Clones are just late stage-twins. The early cloning methods were quite risky but today the clinical methods are quite safe.
>>
>>10484403

For thousands of years, breeders have been selectively breeding the smartest dogs in their liters. This method is probably better than cloning in many ways.

In theory, by cloning the smartest dog the best possible result is creating multiple copies of the same dog with no random mutations. In practice, the clones will (for sure) still get random mutations. Assuming the process is perfect, the dog they are cloning will still have had its DNA deteriorate over the course of its life because of aging.

Cloning will surely produce results that are comparable to inbreeding. I would not be surprised if this is even worse than trying to breed it with its own siblings. What they should have done is taken the award winning dog and mated it with another award winning dog.

This isn't the result of scientific research. This is just a brainlet police department using a commercially available service.

Expanding on this, electricity generation would be much closer to the people who use it. This is a matter of efficiency, less energy will be lost due to transporting it. The only problem is solar panel efficiency and access to materials to produce it, but that takes time and engineering.
>>
>>10485896
That's not automated unless you are talking about heating elements in the road? Automated panel cleaning is done by a robot. Like the one in that image. They are "small", don't use much energy, and would only need to be run a short time out of any given year. It'd be nothing compared to any manner of road cleaning since there are no automated road cleaning things already in use for the majority of roads and such systems are really big, get in the way, and/or resource hogging.

Why do we need to learn about complex numbers if they are imaginary? Numbers that aren't real don't exist in physical reality. Bobby doesn't get i apples from Joey. The boiling point of water is not i. The load on a beam will never be a multiple of i under any corcumstances. When we solve x^2 + 1 we get no solution. The number i is not real, it exists only in he imagination of virginal eggheads. Should we learn about unicorns too because they are imaginary just for the sake of needless masturbatory abstraction?

The last hundred years of physics have depended on the mathematical properties of complex numbers. The complex numbers themselves are never observed in measurements, but the mechanics of the theory depends on them crucially.

Well the first thing you do is look it up on Google Scholar, and click to see people who have cited it. In your case "Enhancing VANET connectivity through roadside units on highways" over 131 citations and multiple related articles, all clearly explaining exactly what the paper is about.

All you have to do in your paper is:
1. What is the main result and how does it compare to what was known before?
2. What is the high-level insight/trick deployed that enabled this improvement?
3. Think of some edge case and try to feed it through their logic ie: their pile of "Combining cases 1 and 2 and substituting into (3)" I just read in the png.

You learn it. Like learning a language. What did it for me was through meditation learning to super focus, and then scrolling through combined pdf:s of math solutions far beyond my ability over and over again, with 3 minute meditation break every 25 minutes. Do this 5 hours every day, when I wake up and hold my eyes closed I see similar math conjured under the eyelids like some tetris effect. Essentially through exposure it's learning to really quickly and intuitively see the overarching theme and understand it not deeply, because I haven't honed in and aimed at it like when solving stuff normally, but you see the overarching manner of solution very quickly like it's in the bonemarrow.

Hello, /sci/, I’m currently writing a fantasy novel, in a world where the gunpowder used to fire bullets from guns is replaced by either water or air pressure. Is such a thing possible, what are foreseeable dangers of using air or water pressure, and how would performance differ from using gunpowder? (Pic not related)

Math isn't invented so the math that humans have discovered would be the same, just remaining undiscovered.

As a student of biology, I am tired of the disrespect biology gets within the scientific community. We use the scientific method in our research just as much as those who study physics and chemistry. Biology isn't a pseudoscience and it has plenty of practical uses. This board is full of autists that can't shake off their egos that have been inflated by shoving their lab buddy's cock up their butt.
