Congratulations and Ευχαριστώ dear Nikos Christodoulides. The Cypriot presidency was a real success. You drove forward our EU agenda, from competitiveness to enlargement. Abroad, you built bridges with our partners in the Middle East at a crucial moment.

Source and context of $\frac{22}{7} - \pi = \int_0^1 (x-x^2)^4 dx/(1+x^2)$?
Possibly the most striking proof of Archimedes's inequality $\pi < 22/7$ is an integral formula for the difference: $$ \frac{22}{7} - \pi = \int_0^1 (x-x^2)^4 \frac{dx}{1+x^2}, $$ where the inte...
