Archimedes Do not disturb my circles! Original form: "noli ... istum disturbare" ("Do not ... disturb that (sand)") — Valerius Maximus, Memorable Doings and Sayings, Book VIII.7.ext.7 (See Chris Rorres (Courant Institute of Mathematical Sciences) – "Death of Archimedes? Sources".). This quote survives only in its Latin version or translation. In modern era, it was paraphrased as Noli turbare circulos meos and then translated to Katharevousa Greek as "?". Reportedly his last words, said to a Roman soldier who, despite being given orders not to, killed Archimedes during the conquest of Syracuse; as quoted in World Literature: An Anthology of Human Experience (1947) by Arthur Christy, p. 655
Archimedes Vitruvius 9.9.10.
Attributed, on discovering the principle of upthrust on a
floating body while having a bath. Archimedes had been given the
task of establishing whether there was the proper weight of
gold in the crown of Hieron of Syracuse. One day when entering
his bath he noticed the water which flowed over the sides as he
entered and he correctly perceived that the weight of the water
displaced was that of the weight of his body.
