This is real, and incredibly dangerous. The Russians ran their first major tryout of cyber warfare to try to shut down Estonia TEN YEARS AGO. It took the Estonians several days to recover, and is why this tiny nation now has awesome cyber defenses https://t.co/4C4hplSUo5 https://t.co/hj53UWiAQF

Richard #Feynman's Integral Trick. (Neat bit of integration. If an integral is hard but depends on a parameter t, try differentiating it with respect to t to see if it could help solve it.) https://t.co/v93YbVKQYy

Should zero be included in the set of natural numbers?

Antimatter is amazing: it means negative numbers are real. Yes, you can have -3 particles: it's called having 3 antiparticles! Just as 3 - 3 = 0, three antiparticles can annihilate three particles of the same kind. But the discovery of antimatter is a funny story (cont.) pic.twitter.com/XWGQFLUDTe

Amazing how much fun can be had with random points on a sphere! A team of mathematicians on Twitter just discovered a cool connection between Catalan numbers and the distance between random points on the sphere in 4d - using the quaternions!https://t.co/g40n7DWAK1

We've discovered a surprising fact about the probability distribution of distances between random points on spheres! A mysterious mathematician known only as "Lucia" finished the job. It's fun having collaborators you don't even know.https://t.co/3TrODkZTLO

#Mathematics is about interesting #algebra processes too. Here's an old one that I very much enjoy: obtaining #Euler's product formula for the #Riemann zeta function involving prime numbers - using only very basic algebra. (Note the rhythm!) pic.twitter.com/z4pLF5rdyc

The equations of general relativity have solutions that describe weird things that probably don't exist but *might*. Einstein didn't believe in the Big Bang and black holes at first. They exist. His theory also allows black holes that move at light speed. Do those exist? pic.twitter.com/5hz2Yt2kvJ

Today we learn about the Spectral Theorem (in a nutshell). If you take a Hermitian matrix, and you diagonalize it, you can break it down into it's "eigen-components," thereby obtaining a representation that is readily generalizable to infinite dimensional Hilbert space. #math pic.twitter.com/hwQ0HCjFpZ

Though matrices don’t generally commute, here’s a simple case where they can be switched around a third matrix. (It’s not hard.) #math #algebra pic.twitter.com/UWlhJPUiEx

Every time I see a person in a coffee shop with a notebook and lots of colored markers I just assume they're a low dimensional topologist.

Enriched profunctors sound scary, but here's a nice one. Two islands C and D with one-way toll roads between some cities - and one-way plane trips from some cities in C to some in D. What's the cheapest trip from E to c? I explain the theory here: https://t.co/a3IYJ0sgrO pic.twitter.com/YtYwsoF9je

Our 3-D model of immune cells attacking tumor cells after testing immunogenicity is fully #opensource. It comes free in every #PhysiCell download! Please feel free to extend it.

The notion of a tensor is a generalization of a vector. Tensors are very essential in #Einstein's General Relativity and in #Quantum theory. Tensor products and tensors are very much related -- by means of tensor products one can build all tensors. #math #physics pic.twitter.com/62kGwkPdRA

In 1977, Kip Thorne and Anna Żytkow figured out what happens when a neutron star - a ball of neutronium 25 kilometers across - hits a normal star. It's called a "Thorne-Żytkow object" or TŻO. Now astronomers may have found one in the Small Magellanic Cloud! Read on.... pic.twitter.com/dr7WK0y6OQ

This is the free modular lattice on 3 generators, where "modular" means A∨(B∧C)=(A∨B)∧(A∨C) when A<B or A<C. The free modular lattice on 4 generators is infinite! This one is connected to representations of the D4 quiver, but big mysteries remain: https://t.co/2PVLAWNpc4 pic.twitter.com/lRCQuyhLDp
