Measuring the Speed of Light With Valentine's Day Chocolate

Cytotoxic writes "What to do with all of those leftover Valentine's Day chocolates? — a common problem for the Slashdot crowd. The folks over at Wired magazine have an answer for you in a nice article showing how to measure the speed of light with a microwave and some chocolate. A simple yet surprisingly accurate method that can be used to introduce the scientific method to children and others in need of a scientific education."

you can use chocolate to measure speed of light

although its far more interesting to use chocolate to measure the speed of digestion

Why bother?

It's approximately 300 000 km/h. 'Nuff said.

Or even, what's this thing called "leftover chocolate?"

Are you sure? My Texas School Board Approved textbook says the speed of light is exactly the speed it takes God to wink. Coincidence? I think not.

This experiment is imprecise and delicious.

This experiment has lots of problems. *nom nom nom* First, microwave ovens don't always precisely match the given frequency. *chomp chomp* Second, and more importantly -- *chew chew swallow* -- identifying the hotspots and measuring the distance between them is difficult and error prone. *nom nom* And that's even when the chocolate is fresh! It's worse after it's already been partially melted. *stuff face* So I had to perform many experiments, using fresh chocolate each time, to get an accurate measurement.

In conclusion, this experiment rules. *nom nom nom nom*

Sheldon Cooper??

Is this what Dr. Sheldon Lee Cooper do on Valentines Day?

Now I am *horny*. There must still be hope in my case...

If a microwave, chocolate, and performing an experiment make you horny...

Let's just hope you never learn what fondue is.

God takes speed to wink... :|

Now this is very informative ;-)

Actually, not that much since you did not specify in which environment it has that "exact speed". Saying the speed of light is 194792442 m/s or any value is just as precise.

Now, saying that c is constant equal to 299792458 m/s is absolutely correct although, the speed of light is actually:

c/n where n is the refraction index.

In a microwave oven at sea level, the speed of light is *approximately* 299792458/1.0003 = 299702547 m/s

Bu bu but... That's the secret ingredient in auntie Curie's "soul warming" chicken casserole!

It warms you up inside, helps you lose weight, AND makes you the brightest one at school, all at once!

Anything else I can do for you today ? My car _really_ needs to be washed... and it would also be nice if you could give the interior a "once over" with a perfect vacuum.
