 MasersA maser is a device that produces an intense and highly focused beam of electromagnetic radiation in the microwave range of the spectrum.

 St. Modesto's Day (2020)St. Modesto is the patron saint of farmers in Greece. His feast day is celebrated with various rituals in honor of farm animals. In Lemnos, kollyva (cooked wheat berries) and holy water are mixed with their fodder, while in Lesbos, the holy water is sprinkled on the fields to ward off locusts and disease.

He is known for a sermon he preached on the bodily Assumption of the Virgin Mary into heaven. More... | |
