Carnival of Mathematics 164

Carnival of Mathematics LogoThe next issue of the Carnival of Mathematics, rounding up blog posts from the month of November, and compiled by Ioana, is now online at Life Through a Mathematician’s Eyes.

The Carnival rounds up maths blog posts from all over the internet, including some from our own Aperiodical. See our Carnival of Mathematics page for more information.

LaTeX/TikZ to draw a star graph $K_{1,n}$

For a diagram for a class this week, I’ve written a LaTeX command to draw star graphs using TikZ. A star graph $K_{1,n}$ is a graph with a single central node, $n$ radial nodes, and $n$ edges connecting the central node to each radial node. I am sharing this here in case it is useful to anyone else.

Big MathsJam Highlights, 2018

The dust is settling on the ninth Big MathsJam, and before I get too sad that it’s nearly a year until the next one, I put down some thoughts about what was so good about this one.

Here are the mathematicians you nominated to go on the new £50 note

The Bank of England has released a preliminary list of names nominated by the public to appear on the new £50 note. I’ve done a bit of analysis on the list, and present here my findings.

To recap: the Bank asked for nominations satisfying the following conditions:

  • have contributed to the field of science
  • be real – so no fictional characters please
  • not be alive – Her Majesty the Queen is the only exception
  • have shaped thought, innovation, leadership or values in the UK
  • inspire people, not divide them

The released list consists of the names that were nominated in the first week, and belong to people who are real, deceased, and contributed to science ‘in any way’. They haven’t divulged the number of times each name was nominated, or the ineligible names.

Euler in maths and engineering

Inspired by Katherine Johnson’s character in the film Hidden Figures and her use of Euler’s Method, engineer Natalie-Claire Luwisha has written this guest post about Euler’s contribution to engineering.

I thoroughly enjoyed Hidden Figures because of the overall message and inspiration it generated for all women, especially women of colour. Even today in the 21st century, most of the STEM (science, technology, engineering and mathematics) industries still have a very low percentage of women and even fewer women of colour. One major factor in this is the lack of visible role models for young girls and women to aspire to, so this story based on real-life events was ideal to help tackle the issue.
