“Teaching has been a wonderful life,” says Linear Algebra champion and retiring math prof Gil Strang, who has spent 75% of his 88 years at MIT. @ScienceMIT https://t.co/VXoqRNig0X

[Tivadar Danka @TivadarDanka]

Matrix multiplication is not easy to understand.

Even looking at the definition used to make me sweat, let alone trying to comprehend the pattern. Yet, there is a stunningly simple explanation behind it.

Let's pull back the curtain!

[Dan Martin @danmartin_7]

My best academic advice is to be quiet as much as possible. Your opinion or enthusiasm might lead to unwanted & unpaid labor.

[Tivadar Danka @TivadarDanka]

The single most undervalued fact of linear algebra: matrices are graphs, and graphs are matrices.

Encoding matrices as graphs is a cheat code, making complex behavior simple to study.

Let me show you how!

This is such an extreme reality in so many spheres of academia

[T. Ryan Gregory 🇨🇦 @TRyanGregory]

University management has no idea of the severe cost to their institutions when their most passionate and creative faculty disengage.

[Dr. Johan Ferreira 🌈 @statisafrican]

@NickyCreux @UPnasagric @Fabiteam1 @UPPlantAndSoil @ResearchUP Very cool!

[AI & Games & ML @AInGAMESnML]

I think I’ve said it before, but I’ll say it again:

Choose a PhD advisor who is nice and supportive, no amount of citations and popularity can replace that!

@Dischem why on earth are there 8am slots for C19 testing, which I booked for, but I arrive at the site, only for it to open at 9am? This is at Olympus, Pta.

[Aylwyn Scally @aylwyn_scally]

Top grant advice from Twitter:
1. Excite the reviewer! Remember when you decided to write a boring grant? That was where you went wrong.
2. Give lots of detail, but also not too much. If you count up the detail and it's not equal to the correct amount, that's a problem.

[Dr. Johan Ferreira 🌈 @statisafrican]

A collaborator from before-turned-brilliant colleague!

Students, please tell your favorite professors that you loved their class. Particularly this year!! It has been a rough one and we could all use that boost to finish the semester.

[Chelsea Parlett @ChelseaParlett]

I don't think you understand, when I sign my emails

"Best,

I am not wishing you well, I am communicating that *I* am in fact, the best Chelsea.

Lesotho vaccination, big ups to the health workers doing their best to get Basotho vaccinated.

“Those who ignore Statistics are condemned to reinvent it” - Bradley Efron.

>20 years later this quote is more relevant than ever.

I am seeing too many #AI, #data science & #ML courses/articles that (deliberately?) ignore statistics content & principles.
