Why was the sundial invented?
Space and AstronomyWhy was the sundial important? The oldest known instrument for telling time, the sundial, allows us to track the position of the sun more accurately. Up until the early 19th century sundials were the main instrument people used to tell time. If they are correctly placed, sundials can be used to accurately tell time down

Why are Cepheids used as standard candles?
Space and AstronomyIt turns out that the rate at which the star pulsates is correlated with how bright the star is. If astronomers can measure the period of a Cepheid variable, they can calculate the absolute magnitude of the star, making Cepheid variables standard candles.Dec 6, 2015 Why can quasars be used as standard candles? Astronomers have
