M.C. Escher (June 17, 1898 – 1972) was a Dutch-Frisian graphic artist. He is known for his often mathematically inspired woodcuts, lithographs, and mezzotints. These feature impossible constructions, explorations of infinity, architecture, and tessellations.

Danish aviation pioneer Jacob Ellehammer was born June 14, 1871 (d. 1946). Originally trained as a watchmaker, Ellehammer quickly got ambitious and started inventing motorbikes, aeroplanes and helicopters. On September 12, 1906 he made a tethered flight (as with most early flights, this one is also disputed), becoming the second European to succeed in making a powered flight. (His helicopter performed a hover as early as 1914!)

After today’s exams, it is a comfort to turn to the wisdom of classical English literature.
"Drink today, and drown all sorrow;You shall perhaps not do it tomorrow;Best, while you have it, use your breath;There is no drinking after death”— Ben Jonson  (c. 11 June 1572 – 1637)
