Weighing the Earth

“A STANDARD experiment which deserves to be carried out more frequently than seems customary is that of weighing the earth. The fact is, the earth weighs something like 6,000,000,000,000,000,000,000 tons; as the scientist would put it, 6 x 10²¹ tons; or in more ordinary language, six thousand-million-million-million tons. Nor is it such a great trick to find this figure with the apparatus that we are able to bring to bear upon the problem,” says the Scientific American.
