|Did you kow that Arcturus (known as the Bear Guardian and is the brightest star in the Bo÷tes constellation) played a key role in opening the Chicago World's Fair of 1933? Light from this star passed through a telescope and was collected on a photoelectric cell that converted starlight into the electricity that turned on the lights to the grounds. Neat, eh? This was 70 years ago. And you thought Granny lived in the Dark Ages!|
Oh, how times have changed.
