If you are at a conference use. the. microphone. It doesn't matter how loud you think you are, it doesn't matter if you are a speaker or audience member. You should try to accommodate people who are hard of hearing (otherwise you're excluding them!)

Yesterday I helped a student with a 3rd year physics course and the lecture had the same letter in the same font and weight representing three different things on the same slide and it was infuriating.

Helped a student with Real Analysis in #MathsToday. We were writing proofs and I was writing sentences on the page in approximately the places they would have to go. “What’s this gap?” “That’s where I’ll tell the reader what N is.” “How will you do that?” “I don’t know yet.”

On the bedtime story front: Three years ago, if you couldn’t make up a bedtime story yourself, you *bought a book* that someone else made with care and heart and read that aloud, thus supporting an artist who took care and gave heart.

Some of you have forgotten that only three years ago you were perfectly capable of writing an essay, writing a eulogy, telling a bedtime story to a child, and it should worry you that powerful companies have convinced us we can’t do things we’ve been doing for 5,000 years.

I've got some stock and a mountain of Sharpies that just won't quit, so if anyone'd like to furnish the discerning bookish history nerd in their life with a chunky tome that focuses on that stuff that all the other history books seem to miss out, now's your chance! #Books #History #Maths

A richly illustrated copy of The Mathematicians’ Library lies open on a wooden surface, featuring a large circular astronomical diagram with zodiacal and planetary markings, surrounded by classical figures. Overlaid text advertises “Author-Signed copies available” and “£25 + £5 p&p (UK only)”.

I’ve realised something today: Quite a few lecturers don’t refer students to Maths Learning Support because they think that what the students are facing isn’t maths (“It’s just charts and percentages. That’s not maths. ”) or that it’s too basic (“That’s just primary school stuff”).

I love that the area of a parabolic arch is 2/3 of base times height. It's so simple.

An arch shaped like a downwards-opening parabola cut off at the bottom with a horizontal line. It's coloured in blue.
The height from base to vertex is labelled with a lowercase h.
The base is labelled with a lowercase b.
To the side and written in blue is the formula A = two thirds b h.

In #MathsToday I helped a student with the trapezoidal rule and Simpson’s rule for numerical integration. It was great to help him translate the frankly complicated notation into something he could use in practice.

I’ve never understood the advice to take time off to solve stress and overwhelm at work. I’ve tried it and it’s never worked. Because all the things at work that cause the stress and overwhelm are always still there when I get back.

Fuck ChatGPT flyers. The future is broadsheets.

A crowded broadsheet with way too many fonts. It says:
