In many ways, the heart is like a tire. Its elastic walls handle immense pressure, and work tirelessly to keep the rest of the body moving. Like a tire, the walls of the heart can wear down over time, the elastic does not spring back as readily as it used to and the tire cannot hold up to the high pressure the way it did when it was new.

Understanding a Solar Eclipse: Then and Now

Thanks to scientific observations with telescopes, satellites and mathematical calculations, we not only understand what happens during a solar eclipse but we can also predict when they will occur and where they will be seen well into the future. 

That hasn’t always been the case. 

Take, for example, the origin of the word eclipse. It’s derived from the ancient Greek word ekleipsis, meaning "abandonment." You get the idea. The folks back then thought the Sun had just turned off. It had, in effect, abandoned the Earth. 

A Deadly Day at Sea: The Fateful Battle of the Atlantic
