sentence1: The closure of a mathematics summer camp in Sirince, Izmir, Turkey by Turkish authorities has drawn scorn from scientists around the world. Professor Alexandre Borovik, who organized some of the opposition, said "We are shocked to learn that the Summer School of Mathematics initiated by Professor Ali Nesin was shut down by local authorities. We found it surprising that such an esteemed mathematician such as Professor Nesin needs a specific permit each time he wants to teach math, as we saw that one of the reasons for shutting the camp down was the lack of such a permit, especially considering how this contradicts the fact that the summer schools organized every year by Professor Nesin are sponsored by The Scientific and Technological Research Council of Turkey (TÜBITAK), Turkish Mathematics Association and many respected Turkish universities."
