The Pi Pico W 2 can run micropython, which is a reasonably limited and fun version of python that is accessible for beginners. If the types of projects you have in mind will involv…

British homes are almost exclusively heated by natural gas boilers; home heating is only a small part of the grid electrical load.

I had to tackle a problem much like this one when analysing the polygons in planar graphs (analysis of planar chemical networks). A fun approach I found was to use a Delaunay trian…

It's obvious that you can't solve hallucinations by curating the dataset when you think about arithmetic. It's trivial to create a corpus of True Maths Facts and verify that they'r…

"Accident & Emergency" - you may know it as the Emergency Room, but it's commonly called A&E in the UK

I love persistent homology; it's such a weirdo bit of maths that topologists keep trying to make useful. Similarly its bigger cousin, Topological Data Analysis, which as far as I c…

A black body will emit radiation (and receive radiation) until it's in equilibrium with its surroundings. In theory, the black bit of box radiates heat into space, and receives som…

Matplotlib for python solves this with a SymLogScale, which is allows you to chart (-10 ^3, - 10^2,..., 10^2, 10^3) in the way that you'd expect. It does this by being linear betwe…

One percentage point is a four relative percent increase here: (25/24) = 1.041

This is mad (especially from a UK perspective!) and it doesn't cover the key point of insurance: you insure risks that you couldn't afford if they went wrong. I insure my house, my…

Some factors you haven't considered: 1) heat pumps make much more sense when you don't burn things to power them. Solar PV, wind, hydro etc powering heat pumps mean you turn energy…
