The Coligny Calendar is a Gallo-Roman luni-solar calendar with a 30-year metonic cycle likely compiled by Druidic leaders in the first century BCE, based partly on earlier Babylonian calendars. Discovered in 1897 near Coligny, France, the bronze plaque fragments show evidence of centuries of adjustments to align lunar and solar years, revealing insights into Gallo-Roman timekeeping science. The calendar divides the year into twelve named months plus intercalary months, with each month split into two fortnights tracked by movable pegs.
The Montessori method is an educational approach developed by Italian physician Maria Montessori in the early 20th century that emphasizes hands-on learning, student autonomy, and natural curiosity over formal teaching and grades. The method spread globally from Italy to the United States and beyond, though it faced opposition from the American educational establishment before resurging in the 1960s. Scientific studies generally report favorable outcomes for students using this approach.
