You're welcome!
I just did a back-of-the-envelope calculation that I can hardly believe: If we imagined scaling up the kapton cylinder to the size of the famous NASA Vehicle Assemble Building, the VAB, at Cape Kennedy, it would weigh..... 0.0016 kilograms, equal to 0.0564383 ounce!!! I am calculating with the cylinder being 1 cm. long. The VAB is 160 meters high. Could somebody try to check my result, as I said I can hardly believe it myself... |

I just did a back-of-the-envelope calculation that I can hardly believe: It can happen! Last year I wrote an article in the RSC's Chemistry World magazine asking people to speculate on the following question: "Imagine all the sodium chloride in all the world's oceans crystallised into one enormous prismatic salt crystal with a 1cm x 1cm base. How long/tall would it be?". I then provided the scarcely believable answer - 20,000 light years! |
