They said I should start twitting. I said the pitch of my voice is too low. They said I live in the past and dragged me here.

@desrepeerc @fermatslibrary Simple, the probability to get six 9s in a row for a fair random generator is 10^(-6). Multiply this by the probability NOT to get this sequence anywhere in the first 761 digits, which is [1-10^(-6)]^(761-6).

Fascinating slow-motion footage of what happens when a droplet falls into a pool of water, a phenomenon known as a coalescence cascade.

@fermatslibrary This proof works only in linear media, where D and H are linear in E and B, respectively. Keeping all the four fields makes the passage to the line above the wave equation more involved.

@newstart_2024 It's no use posting this without reference t the original report.

@fermatslibrary The concept is correct, but century starts at 1/1/2001. Therefore, from the 16th century onward, no century has started and will start on Sunday, Wednesday or Friday.

Last call!

@Anthony_Bonato Then you should improve your spelling :)

[RafiB @Rafi_Physics]

@EfraSereno @fermatslibrary Correct, that's what I'm saying. And repeating 'greatest' doesn't make it true. Other physicists were much deeper thinkers and broader in their discoveries, e.g., Maxwell, Feynman, Landau ...

@fermatslibrary This amounts to fewer than 900 books; it's not a breakdown!

@QuantaMagazine @preskill We have this hammer but so far not much to use it for. Hang on, is this a nail out there? Yay!

[RafiB @Rafi_Physics]

@SubirSachdev All very nice posting here, but it would have been nice if you also did your job as an editor in IOP rather than let papers and appeals fester for months on end!

[RafiB @Rafi_Physics]

Sent an appeal to Reports on Progress in Physics on December 17. Silece! An enquiry on Feb. 21(!) was forwarded to the editor-in-chief, Subir Sachdev, with the promise of response "shortly”. Still waiting. Stay away from ROPP and IOP!

I fixed an (embarrassing) error in my arXiv paper:
"Granular solids transmit stress as two-phase composites":
https://t.co/jO2RJBnoZf.
Happy to discuss it.

[RafiB @Rafi_Physics]

@JAM_KseniYa @fermatslibrary Two reasons. One is there may be a practical application of it to cryptography. However, the more important reason for pure mathematicians, for whom mathematics is an art form, is that it's a challenge and it's there.

[RafiB @Rafi_Physics]

@ soil mechanicians and geotechnical engineers: could this be the way to model stress in granular media away from the debatable critical state? https://t.co/IRtsYt1wfA

@fermatslibrary This seems to be incomplete in showing that 'if either the sum or the product of e and pi is irrational then the other is rational'. In the shown polynomial BOTH coefficients can be irrational, not violating the fact that e and pi are transcendental. (???)

[RafiB @Rafi_Physics]

@IEinav My condolences, Itai and Hilit. Words fail to express feelings, but we're thinking of you. Much love!

[RafiB @Rafi_Physics]

@1CatherineAnne 🤔I think you'll be ok.
