Go here to watch a cool video: they say that now there is an engine that could move objects with a speed of light. Do you believe it?  

Can you express the speed of light in scientific notation? Just give your answer in comments below.

Too easy? Then, create your own - more challenging problems!

The accuracy of the measurement, though, is amazing! Of course, Dr. Z is easy to amaze. Maybe, this is why he thinks that the life is amazing. Despite, Everyday Life problems. Better say, life challenges. 

Talking about challenges, how long do you think will it take to measure speed of light with accuracy to a cm, mm, mkm, nm, etc. Can you express these prefexes in scientific notation? 

Boring? How about this cool video with short takes from Gravity Effect songs?
