reminds me of my folks! dude, I'm emailing this to my dad!
Where do you get a cesium clock from anyway?
Maybe some of you want your kids to work at McDonald's, but don't criticize this guy for exposing his to science.
Involve kids in science! What is all this negativity because he included his kids in an experiment? This guy proved something. Hate nerds--that's okay because it won't change the fact that your world works because of them.
Ummm well I am glad he did this because I would not. I would rather spend my time and money on a more interesting endevour such as exploring new parts of the country and actually not wasting so much fuel.
This guy had kids? They should really screen out nerds (especially physics nerds) from being adoptive parents...
That's an awesome experiment! I would love to try that myself, I wonder how much it would cost to get my hands on these clocks...
Very geeky and creative
Special Relativity vs. General Relativity
In his 1905 paper about Special Relativity Einstein correctly predicted that an object in motion experiences a slow down in time with respect to a stationary observer. However, special relativity lacked some important aspects. It only dealt with objects at constant speeds, but not acceleration or deceleration. It took Einstein another ten years to fill in the missing pieces. In 1915 he wrote the paper on General Relativity. Interestingly he used Gedankenexperiments very similar to the ones of Galileo Galilei to explain the Principle of Equivalence. He came to the important realization that an accelerating object experiences the same relativistic effects as an object in a gravitational field... but I digress.
To sum it up. As you drive your cesium clocks up on a mountain, the time in your car passes slower with respect to the reference clocks at home as predicted by STR. But since the gravity is lower at higher altitudes, your time passes faster in the mountains.
That is the most impressive thing: to perform relativity experiments in the company of small children.
seems like a waste of fuel
"That is so bad for your car to idle for hours and hours"
Who cares?! There's science to be done!
I wish my dad were this cool.
... and I thought that I was a scarily geeky dad!
lol I think wvwvwwvvw said it best
Absolutely brilliant. I love the fact that you got the kids involved. Im a bit of a self trained physics buff and my 6 year old daughter is always asking more and more physics related questions. She would love this experiment.
Guy proves for himself the theory of relativity with homemade experiment! And a fun family trip. (Albeit with a lot of wasted gas and needless pollution). :-P
