Wodny spektakl
Czy jest wśród Was ktoś, kto nie słyszał o wodospadzie Niagara? Wodospad ten znajduje się na granicy Kanady i Stanów Zjednoczonych. Nie jest największy na świecie, nie niesie najwięcej wody. W czym tkwi jego magia?
Szczęśliwego 31²+27²+17²+6² roku…
W tytule występuje oczywiście liczba 2015, przedstawiona w postaci sumy czterech kwadratów liczb całkowitych. Matematycy często dla zabawy używają tego rodzaju przedstawień, składając życzenia noworoczne lub urodzinowe.
