The middle day of the days counted, so one week of news cannot move it. The line under it is the last 60 days, one point a day.
Something wrong?A Stoic polymath who tried to measure the sun's distance, calculate Earth's diameter, and link the moon to the tides - then lost every word he wrote, leaving later scholars to mine the wreckage for what the most learned man of his era once knew.

Riches are a cause of evil, not because, of themselves, they do any evil, but because they goad men on so that they are ready to do evil.
A single day among the learned lasts longer than the longest life of the ignorant.
Things which bestow upon the soul no greatness or confidence or freedom from care are not goods.
About this person
Born around 135 BC in Apamea, Syria, Posidonius studied Stoic philosophy under Panaetius in Athens before spending years traveling Spain, Africa, Italy, Gaul, and the Adriatic coast for scientific research. He settled in Rhodes as a teacher, drawing scholars from across the Mediterranean and becoming known to Roman power brokers like Pompey and Cicero - key to pushing Stoicism into Roman intellectual life. He wrote more than twenty works blending Stoic doctrine with Plato and Aristotle, and pursued genuine questions in astronomy, geography, mathematics, and natural history: the size of the sun, the diameter of the earth, the moon's pull on the tides. All of it is gone now, surviving only as fragments and citations in the texts of those who came after.
