Every year on March 14 the world celebrates the beauty of maths. That's because when you write the date the American way — with the month coming first — you get 3/14. And 3, 1, and 4 are the first three digits of $\pi$, one of the most important numbers in maths.

Mathematics is incredibly important to our lives, but it still often hides in the wings. This is why we're extremely pleased that on Monday, 20 early career mathematicians got to present their work to politicians in Parliament, via the STEM for BRITAIN competition. This annual event invites researchers in maths, engineering, the biological and biomedical sciences, chemistry, and physics to submit posters explaining their work.
