Only a Trillion is a collection of ten science essays and three scientific spoof articles by Isaac Asimov. It was the first collection of science essays published by Asimov. It was first published by Abelard-Schuman in 1957. A paperback edition published by Ace Books in 1976 included updates of outdated material (re-issued in 1980). The book was also published under the title Marvels of Science by Collier Books in 1962.

The title refers to the number of atoms of astatine-215 in the top 10 miles of the Earth's crust of the North and South American continents – only a trillion.

Reception

Floyd C. Gale stated that Asimov "[a]lmost certainly had enormous fun writing this collection of articles. He staggers, frightens, amazes and, in two, fiendishly misleads his reader".^[1]

Following the publication of Only a Trillion, Asimov compiled several more science essays into the manuscript for another, similar book titled Only a Light-Year, but that book was never published, because Only a Trillion had not sold enough copies.^[2]
