Albert Einstein Day

Diana Asked:

Hi Tanner,

What did Albert Einstein do to become so famous? Was it a really hard math problem he solved? 

How did Groundhog day become a national holiday?

Albert Einstein became famous when he came up with the theory of relativity, which is actually two theories - Special Relativity and General Relativity.

General Relativity

Says that large objects cause space to bend in the same way that putting a tennis ball on a thin sheet would cause the sheet to bend. The larger the object, the more space bends.

Special Relativity

Says it's impossible to determine if you're moving unless you can look at another object.   It also shows that measurements of distance and time depend on how fast you are traveling. This means that if someone your age goes into space for ten years and travels millions of miles, that person will come back looking two years younger than you!

Groundhog Day

Started in America among the Pennsylvania German communities in the 18th and 19th centuries as a traditional celebration to predict the beginning of spring.
