Why do your socks get stuck in your duvet cover?

Oxford Sparks are looking for someone to explain why all of the small bits of washing end up inside your duvet?

This major issue is in the news because one of their videos was taken up by Radio Oxford and the DJ sprung the duvet question on them during the live interview.

So they are looking for someone to give an answer to the question, ideally a mathematical answer, in video form.

If you are interested, contact Dyrol. They will make the video with you.

On the $(k+2,k)$-problem of Brown, Erdős and Sós

Oleg Pikhurko
(University of Warwick)
Abstract

Brown-Erdős-Sós initiated the study of the maximum number of edges in an $n$-vertex $r$-graph such that no $k$ edges span at most $s$ vertices. If $s=rk-2k+2$ then this function is quadratic in $n$ and its asymptotic was previously known for $k=2,3,4$. I will present joint work with Stefan Glock, Jaehoon Kim, Lyuben Lichev and Shumin Sun where we resolve the cases $k=5,6,7$.

Oxford Mathematics Public Lecture: Logging the World - Oliver Johnson

During the pandemic, you may have seen graphs of data plotted on strange-looking (logarithmic) scales. Oliver will explain some of the basics and history of logarithms, and show why they are a natural tool to represent numbers ranging from COVID data to Instagram followers. In fact, we’ll see how logarithms can even help us understand information itself in a mathematical way.

RSL Nature Walk, 13:00-14:00, Monday 5 February

For those who like a nice walk outside, the Radcliffe Science Library (RSL) will be conducting another Nature Walk around University Parks. 

Spring flowers are just starting to emerge so it should be a relaxing and not too cold experience. 

Meet before 13.00 in the Wellbeing Room in the RSL.
