Determinants were discovered (or invented) before matrices.

2. One retweet per 32 followers:

This number has 317 digits, all ones. It's prime. 317 is also prime!

That's not a coincidence. A number whose digits are all 1 can only be prime if the number of digits is prime!

This works in any base, not just base ten. Can you see the quick proof?

'Making new things from old things' is a common theme in math. Ex: given two vectors we can make a new one by 1) stacking or 2) multiplying then stacking. Option 2 gives rise to the tensor product—now on the blog! “The Tensor Product, Demystified” https://t.co/09Sn819y3Y pic.twitter.com/XtU0Hpz6F8

Me parece impresionante este cuadrado mágico que, cuándo escribimos sus números en inglés y los sustituimos por la cantidad de letras que definen cada número, nos devuelve otro cuadrado mágico. #Cuadraception #CuadradoAlfaMágico #MathLife https://t.co/ZPRgs73j22

The equivalence of the Euler-Lagrange equations of motion and the Hamilton equations in Classical #Mechanics isn't hard to show. In my view, Classical Mechanics is probably the most mathematically rigorous and elegant of physical theories. #physics #math pic.twitter.com/o2RBpNbQ4I

Today's philosophy of maths lecture: Computability. What is computability? Is there a hierarchy of computational power? Can every mathematical question be solved in principle by computation? https://t.co/9hcqv9udC3

Yay! Starting May 20th in 2019, the kilogram will be defined using Planck's constant, the speed of light, and the frequency of a very specific kind of light emitted by a cesium atom!

Until now it was defined as the mass of this chunk of metal in Paris.

Learn how former Queen guitarist (now astrophysicist) Brian May used primes as a source of quasirandomness to make the stomp-stomp-clap in “We Will Rock You” sound as if it was coming from a real audience. (Can anyone give more details? an oscilloscope plot showing the delays?) https://t.co/9auUCYoSvO

You can take 8 perfectly rigid regular tetrahedra and connect them along their edges to form a ring that you can turn inside-out!

It's called a 'kaleidocycle', and you can make one with any even number of tetrahedra, as long as you have at least 8.

Although #quantum mechanics goes beyond classical Newtonian mechanics, the average or expected value of momentum still obeys #Newton's Second Law of motion F = ma (as demonstrated in this slide). #physics #mechanics #math pic.twitter.com/5LpUQJFJCS

In my calculations today I found it useful to apply the companion matrix of a polynomial. It's a simple and direct way to write down a matrix that has any prescribed (monic) polynomial as it characteristic (or minimal) polynomial). #math #algebra pic.twitter.com/ogEi6OVS7y
