Hannah Fry will be presenting this year's (2019) edition of the Lectures at the Royal Institution, aiming to illustrate the power of in tackling complex systems, but also its possible limitations.

The #PSLE papers in #Singapore have always caused stress for 12-year-olds and their parents, but the #mathematics paper tends to be outed as unfairly difficult. This CNA #documentary looks at whether the #maths tests are being set as unreasonably hard against the kids, and if public reaction is overblown.

Quanta article briefly explaining the problem of finding progressions within any set of numbers, and Sarah Peluse's proof showing a threshold size beyond which any set must contain a particular type of polynomial progression

Extensive article looking back on the life of Julia Robinson and her contribution to problems involving Diophatine equations

Probing some mathematical minds here: how novel is this way of solving a general quadratic equation \(x^2 + Bx + C = 0\)? Kinda looks like a corollary of "completing the square", or am I mistaken?

Chu and Hough have determined how many steps it takes to randomize (for two definitions of "random") a 15 sliding puzzle, by analysis of the transition matrix of the modelling the process. Turns out to be way greater than predicted by Diaconis, who originally proposed this problem in 1988.

"As a homage to the legacy of the late Iranian Maryam Mirzakhani, the Breakthrough Prize Foundation has launched an award named after her to honour outstanding in the field of .

The $50,000 Maryam Mirzakhani New Frontiers Prize, which may be shared by two or more individuals, will be presented to early-career, women mathematicians who have completed their PhDs in the past two years."

In light of 's recent birthday, thought it'd be relevant to bring up Wikiproject in this instance:

Within the massive ecosystem of Wikidata entries, this project focuses on capturing and organizing data around (entities, sequences, algorithms, theorems, mathematicians, etc.)

Big update: I'm officially graduating with B.Sc. in applied πŸŽ† 🎊

Very anxiously waiting for the graduation ceremony in less than 6 hours 😨

Still gunning for extra certification courses to narrow skill gaps though

First I've heard of the obscure Lill's method, but a fascinating way to solve a polynomial equation 🐒 youtube.com/watch?v=IUC-8P0zXe

To promote her book related to , Hannah Fry did a at the Royal Institution on the pros and cons of using an to make real-world decisions

First time I heard of while perusing Twitter

Not a super popular hashtag, but as the translation suggests, aim is to make the most "uncomfortable" graph; seems open to interpretation (bizarre? freaky?)

Example that I copied (cockroach?): desmos.com/calculator/ksxomdhn

All these years and I'd never heard of the x/y-coordinate of a 2D-point described as the abscissa/ordinate until recently

Not sure if I'd be more attracted to or repulsed from maths if I were exposed to that terminology when beginning to learn graphs + calculus

"... This question is the subject of the β€œweak Pinsker conjecture,” which was first posed in the 1970s. Austin’s proof of the conjecture provides an elegantly intuitive lens through which to think about all manner of bewildering phenomena. He showed that at their heart, each of these dynamical systems is its own blend of chance and determinism."

Update: *just* managed to squeeze the whole Completeness Theorem proof into the single lecture. Boy the construction process and the reasoning behind it are extremely tedious 😞
