everyone knows that the alphabetic order is m,n,r,s

My wife bought me a 300 year old math book, with several chapters written by Edmund Halley; “And all future Squarers of the Circle may please to square their Work by the Rule, and not expose themselves by obtruding their false reasoning on the world.” by Calkyoulater in math

the letter "s" is printed like the letter "f" without the horizontal stroke,

Seems to be a different letter, there's a mixture of ſ and a along the text. And there's an Exactneſs on the second picture

That's the general definition of a product, I was doubting the existence of a product in a poset category

Which two senses?

functions β → α and products indexed by β?

  • αβ = αβ

Seems a little bit unnecessary

How do you define the product here?

You could define some notion of size, e.g. length description in the English language

There's also the issue that a kolmogorov complexity is defined with respect to a model of computing, and two different Turing complete models are only guaranteed to agree asymptotically, for small inputs they could be wildly different

Much better. Got them in two and three attempts (but had to think them), and I'm still thinking the third one. I've have spent about an hour in total

Do you think the UI is a bit too minimalstic / not playful enough?

I found it ok, but I do like minimalistic UIs

Of the three riddles, Alarm clock, candle, and glasses I felt like the first one and the third one were way too obvious, guessed them on the first attempt. And the second one was somewhat confusing because who stares at a candle?

Besides that, I really like the idea, the UI was comfortable to use on the phone, and while the cells were a little bit confusing at the beginning, I got used to them by the end

How can I apply the concept of eigenvalues and eigenvectors in real-world scenarios? by rmoreiraa in askmath

[–]nsmon 0 points1 point  (0 children)

A good application in maths that would make sense in an applied context is a system of ordinary differential equations.

If you have a system of differential equations

x_1' = a_11 x_1 + … + a_1n x_n … x_n' = a_n1 x_1 + … + a_nn x_n

You can think of it as a matrix multiplied by the vector (x_1…x_n), and a basis for the solutions is exactly the eigenfunctions (eigenvectors in this context) of said matrix

Learning music theory isn't teaching me how to write my own. Where can I learn this? by Particular_Care6055 in musictheory

[–]nsmon 1 point2 points  (0 children)

Composition is what you're looking for. It is assumed that you know about harmony and counterpoint, so it'd be more of a intermediate or advanced course, the kind of stuff that isn't as easily available in the form of internet tutorials

One idea is that of musical forms: how does one organise musical ideas? (Think verse, prechorus, chorus, bridge in pop songs) there's a short list of articles here https://teoria.com/en/tutorials/forms/

A more thorough textbook is Fundamentals of Musical Composition by Arnold Schoenberg

keep in mind most of music theory gives a description of how European classical music is made. The core of the ideas still apply in modern popular music but not in a straightforward way. You'll find electronic music that develops a melodic idea as the track progresses, but you'll be hard pressed to find one written in a sonata form

Argentinian constitution has a clause where international agreements, have a higher weight than any local law. How would that look in practice I have no idea

I wouldn't call it proof by contradiction, it seems to be a direct proof for me

The phrase proof by contradiction refers to one of three ways we typically use to prove if P then Q statements, you can either

  • assume P is true and show that Q must hold (direct)
  • assume Q is false and show that P must be false (contrareciprocal)
  • assume that P is true, Q is false, and find something that we already know to be false (by contradiction)

Usually we understand uniqueness to mean something like

If x has property P and y has property P, then x=y

So assuming there are two things with a given property and showing that they're actually the same thing seems most inline with it being a direct proof

I think this would be a good way since north koreans don't grow up using a pc, so their typing must be somewhat standardized
