摘要：
这种情况总是发生：你有一场晚宴演讲，却什么都没准备。你的招牌菜从不失手，但你已经端上它太多次了，想用新东西给客人惊喜。试试这些对高级料理经典的快速、轻快且色彩缤纷的重新诠释，比如（非交换）傅里叶变换和有限群的 Plancherel 定理。
英文摘要：
It always happens: you have a talk for dinner and nothing prepared. Your signature dish never fails, but you have served it too many times already and you'd like to surprise your guests with something new. Try these quick, light and colourful reinterpretations of haute cuisine classics, like (nonabelian) Fourier transforms and the Plancherel theorem for finite groups.
