This is what our planet looks like from 1.5 billion kilometers away. The Cassini spacecraft captures the Earth as a pale blue dot beneath the rings of Saturn.

@Plinz The first sentence looks like an axiom. Not sure you can prove that.

@LauraDeming Moreover Noether’s theorem insures that for each symmetry there is an associated conserved current. F=ma for example is a consequence of invariance under spatial translation in classical mechanics.

[Raphaël Cherrier @raphaelcherrier]

@LauraDeming You can thank Emmy Noether for it!

Fundamental physics laws are assumed to be invariant under some symmetries. This imposes constraints on the admissible terms in the Lagrangian which make them quite simple.

One of the dangers of good-enough-to-fool-you language models: they’re not telling the truth. Only it’s good enough so you can’t tell the difference.

Of course this is AI-generated, not anything I would ever say. If you’d rather be taught by GPT-3 than by humans who know what they are talking about, I guess this is for you.

Madrid, Spain is planning a 74km forest belt around the city with walking & bike paths, play areas, & biodiversity/wildlife corridors, to clean & cool the air, absorb carbon & improve quality of life. Part of its anti-pollution strategy.

Vision.

There is a misconception that most successful tweets are brilliant.

Most highly retweeted and liked tweets I come across are not. They are not even smart. But important traits are image and sense of audience. They distill fashionable tropes and are willing to pander doing so.

@HubNature At cold temperature the metal is ferromagnetic. Its magnetic moment aligns with magnetic field. And it levitates because of the gradient in magnetic field. Heats up with induction. Then undergoes a phase transition and becomes paramagnetic. Falls down.

Do we need multiple heads and wider FFN layers in Transformers? No.

Our work, DeLighT, effectively replaces these components with single-headed attention and light-weight FFN layers.
