Suppose that g:R -> R is a continuous function on the reals such that g(2x) = 2g(x) for all x. Does it follow that g(3x) = 3g(x) for all x? #math

お,強い主張だ.「「外部人材の理事」や「実務経験のある教員による科目」を一定割合以上にするよう要件を設けた。」に対して「支離滅裂で議論に値しない」(電気通信大)| 高等教育無償化:政府の要件7割反対 国立大「筋通らず」 - 毎日新聞 https://t.co/NKJZO7jwAd

In my new Mathematical Enchantments post, I talk about four-dimensional space, which is sort of like three-dimensional space, only spacey-wacey-er. Lots of pictures! https://t.co/dQI79MUyWP pic.twitter.com/wHvNH8yNfh

Mind-blowing science in a mere "remark". "Frobenius manifolds" show up in topological string theory. Now arXiv:1805.02286 shows that at each point of such a manifold there's sitting an automaton - a probabilistic finite-state machine. Zounds! pic.twitter.com/WchPVbjcTN

My book with @JacobBiamonte is out! Learn how quantum ideas like Feynman diagrams can be applied to population biology! Learn how Petri nets let you do computation with chemistry! Plus, it's got a cartoon of me pulling a rabbit out of a hat. https://t.co/gxXYKl4Eo7 pic.twitter.com/T2OKHDkjwn

Liouville's Theorem tells us when an integral is not elementary. For example, it shows why the indefinite integral of functions like exp(x^2) are not expressible in terms of the elementary functions of #calculus. #math pic.twitter.com/O8XLrzwlJe

On my blog Matteo Polettini explains "effective" thermodynamics, where we only know _some_ of what's flowing into or out of an open system. In reality all systems are open, and we never have complete knowledge of inflows our outflows, so this is big: https://t.co/zWmhcfbSzH pic.twitter.com/t6t6kpzbXi

Here's a math riddle for your Friday:

We often ignore the side-effects of what we do, like the "waste" shown in red here. That's one reason we're in trouble. But category theory can make this process of ignoring into a functor! Then, left and right adjoints can help us "un-ignore": https://t.co/wUhc3YjKds pic.twitter.com/4Zp0B9gsoz

The Dirac current is a very basic quantity in #quantum field theory since it gives interactions between particles/fields. Here is an example that hopefully motivates why it is as it's often written. (The conjugation here is the Dirac conjugate.) #physics #math pic.twitter.com/OJ83Kgl2TG

There is a crucial place for ugly mathematics. It can often be necessary on the journey to beautiful mathematics. Let’s not hide the struggle from our students lest they consider themselves not up to the task when they can’t create beauty with a first (or second) attempt. https://t.co/HWQDs024pG

“Lessons from Math Degree That Have Nothing to do with Math”. Item 6 breaks my heart a little, but I love the overall message. https://t.co/7nDeMJPvaa @mathblogging #mbpick

Nice to see my friend @carlorovelli's new book on the nature of time comes in an audiobook version read by... Benedict Cumberbatch! Rovelli is right, the coolest discovery of 20th-century physics is that "now" has no absolute meaning.https://t.co/5KIneEypJv pic.twitter.com/B9iyWMVSi3

Mathematical pet peeve: When news sources use “exponentially” when they really mean “substantially”, e.g. traffic
