The DNA double helix as a visible sign of science complements the Latin motto's optimistic invocation of science:
TEMPUS FUGIT AUGEBITUR SCIENTIA
Time flies. Knowledge will increase.
We owe the mixed augebitur scientia to the title page of Francis Bacon's Instauratio Magna of 1620 which reads: Multi pertransibunt et augebitur scientia, "Many shall pass through, and knowledge shall increase," with an image of two ships sailing on the ocean, setting out beyond the Pillars of Hercules.
