"The great body of physical science, a great deal of the essential facts of financial science, and endless social and political problems are only accessible and only thinkable to those who have had a sound training in mathematical analysis, and the time may not be very remote when it will be understood that for complete initiation as an efficient citizen [...]" – H.G.

Photographic portrait of H.G. Wells, and a quote : "The great body of physical science, a great deal of the essential facts of financial science, and endless social and political problems are only accessible and only thinkable to those who have had a sound training in mathematical analysis, and the time may not be very remote when it will be understood that for complete initiation as an efficient citizen [...], it is as necessary to be able to compute, to think in averages and maxima and minima, as it is now to be able to read and write."

I've become interested in polyominoes recently and have had a few questions about them I couldn't easily find answers to. Here's one:

Let's call an n-omino "balanced" if its 2 colouring has \(\lfloor\frac{n}{2}\rfloor\) cells of one colour and \(\lceil\frac{n}{2}\rceil\) cells of the other colour. Is there a nice structural characterisation of balanced n-ominoes?

I am looking at tilings of a certain kind and I can rule out unbalanced n-ominoes and non-trees. So I am particularly interested in what balanced trees look like.

Follow up: is every 2-connected n-omino balanced?

Theorem of the Day (February 4, 2026) : Theorems of Euler and Rényi on 'e'

Comprehensive presentation of 2 "Theorems of the Day", starting with a statement of these theorems : 

- A Theorem of Leonhard Euler... : Among the permutations of n objects, the proportion of those which move every object is asymptotic to 1/e.
- ... and one of Alfréd Rényi : Among the forests on n labelled vertices, the proportion of those which are connected is asymptotic to 1/√e.

How can angle BPC (labelled x) be found using basic circle theorems/geometry?

Do I need some construction lines to unlock the problem, perhaps through the use of similar triangles APC and BPD?

Thank you in advance for any help offered.

#maths #mathematics #geometry

A circle with two chords (AB and CD) intersecting at point P. CD is a diameter measuring 24, with P splitting it into lengths of 20 and 4. AB measures 21 and P splits this into lengths of 16 and 5. The obtuse angle BPC is marked in red and labelled x.
