@sp_monte_carlo @ProfKinyon With the caveat that RKF has been greatly improved on in turn, and is never the best option nowadays. Of course, for simple applications it will often do fine.

@five9a2 It's easy to assume, from a distance, that one knows how they think and feel, just as it's easy to conflate KAUST with KFUPM (rather like conflating Berkeley with BYU!). But they are human beings who can and do speak for themselves.

[David Ketcheson @DavidKetch]

@five9a2 So I will just say that I think you would find it revealing to speak with women who work at KAUST and with the people you describe as indentured servants. I have known many wonderful and talented people in both groups and their perspective might surprise you.

[David Ketcheson @DavidKetch]

@five9a2 Yes, those are fair points.

[David Ketcheson @DavidKetch]

@five9a2 If I have to review a paper where I don't already know the related literature well, lateral reading is the first thing I do. The same goes for when I am learning about a new subfield or topic. I don't buy the idea that academics aren't great at using lateral reading.

@corless_rob @sam_power_825 Wow, I remember following this trail just a couple of years ago. I was developing something that is somewhat similar but with a different goal (structure preservation rather than dealing with stiffness).

Are any of you other journal editors finding it nearly impossible to get referees these days? I've had record numbers of invitations declined since March.

@hendysh You may be interested in this related work (from a more general and abstract mathematical perspective): https://t.co/MNBm71FvLn

My next preprint (in the works) will take into account our prior knowledge about individual levels of risk and show even better ways to prevent deaths from #COVIDー19

New preprint on the optimal use of social distancing to control an epidemic: https://t.co/MtyGglOPVa #COVIDー19 #Social_Distancing Implementing these kinds of strategies is the real way to save lives in the long run, and will require ubiquitous testing.

I gave an interview about the mathematics of the COVID-19 pandemic in KAUST's weekly podcast: https://t.co/fYOM4rveI4

@knsalama I like it! Could you share what tools you used to make this? And how long it took?

I've never tweeted anything political before. May not ever again. If you don't know firsthand what is really happening in Venezuela, please watch this short, clear and accurate video.

[Joanna Hausmann Jatar @Joannahausmann]

There is far too much misinformation and oversimplification about the situation in Venezuela. https://t.co/V59dGMAbwx

[NetBlocks @netblocks]

Confirmed: Evidence of total internet blackouts across regions of #Venezuela lasting over 28 hours; increasingly severe disruptions now in effect #KeepItOn
