Description

Finding the Speed of Light: The 1676 Discovery That Dazzled the WorldMore than two centuries before Einstein, using a crude telescope and a mechanical timepiece, Danish astronomer Ole Romer measured the speed of light with astounding accuracy. How was he able to do this when most scientists didn't even believe that light traveled? Like many paradigm shattering discoveries, Romer's was accidental. Night after night he was timing the disappearance and reappearance of Jupiter's moon Io behind the huge, distant planet.

More than two centuries before Einstein, using a crude telescope and a mechanical timepiece, Danish astronomer Ole Romer measured the speed of light with astounding accuracy. How was he able to do this when most scientists didn't even believe that light traveled? Like many paradigm-shattering discoveries, Romer's was accidental. Night after night he was timing the disappearance and reappearance of Jupiter's moon Io behind the huge, distant planet. Eventually he realized that the discrepancies in his measurements could have only one explanation: Light had a speed, and it took longer to reach Earth when Earth was farther from Jupiter. All he needed then to calculate light's speed was some fancy geometry.

Nice product but size is not as expected
Size: 3X-Large, Color: Green White
This shirt is really nice and really stands out only downside is the size isn't as expected. I usually wear a 2xl and decided to go with a 3xl and it was still a bit too fitted for me liking..Disappointed I couldnt use it

Snazzy!
Pretty good shirt, embracing my Sopranos/ Goodfellas in the daily life. However, the red is soooo much darker than shown, otherwise it would be a 5 Star.
