"This title contains information"
How can we mathematically test the claim made in the title? In this talk, we will learn about Claude Shannon's entropy and determine if it gives us the best measure of informativeness. If you can picture the graph of a logarithm, you are well prepared.

"Diophantine equations involving the Euler totient function"
We deal with various Diophantine equations involving the Euler totient function. In particular, for $a,b,c,m,n\in\mathbb{N}$ with $m\geq 2$ we study the equations $\varphi(ax^m)=\frac{b\cdot n!}{c}$ and $\varphi\left(\frac{b\cdot n!}{c}\right)=ax^m$ where $\varphi(x)$ is the Euler totient function. We also deal with similar equations involving Lucas sequences of the first kind and second kind, generalising the work of Luca and Stanica.
