Ira M. Freeman (1905–1987)

1955 Fun with radioactivity!

Published for middle-grade to high-school aged readers, this is an introduction to the history of the science to determine the structure of matter. It begins with the suppositions of the early Greeks, meanders around some, lingers lovingly on the work of John Dalton especially. Then really flies with the advances of Einstein and Fermi, and then tip toes on the A bombs on Japan, the later H bomb tests, and resumes speed with the last chapters of "isn't progress show more wonderful" with the many uses of isotopes and zapped elements elements mankind has discovered. The gas ethylene + gamma rays of radio cobolt = Polyethylene, hurray!

I can't say that I followed all the science more than superficially Of course not, I'd be a nuclear physicist if I could. But sometimes the text made giant scientific leaps in a single bound and I felt extra wobbly and left behind. It was fun, though, how it used clever analogies to put the energy and size of an atom into perspective.

For example, if one atom were blown up to the size of an American football stadium, the atom's nucleus would be the size of a BB pellet on the 50 yard line.

Here was another tidbit that related especially to the industry that dominates my location: oil. Single pipelines carry various oil grades. In 1955, at least, the grades could now be separated by "little squirts" of radioactive oil when the grade changes, which is then detected "by workers" and valves are used to send the new grade to their different storage tanks. I know enough people in the oil industry that I should be able to ask more about this technique and if it is still used. But whether anyone knows, in spite of livelihoods being made, would be interesting in itself.

In the end, I was hurrahing for all the advancements. Yippee! Especially in medicine. And just think how we've had more time to play around with all the wonders (and disasters) for an additional 70 years since this book was published.

I do wonder, though, if there isn't an analogy that could be made of the atom with the value of human knowledge? That, like energy and mass, nothing is ever really made or lost, only changed.

What a book to mark my 200th book read in 2024.

Everyday physics explained in simple terms. Almost no math, just simple commentary. A place to begin for young students interested in physics.

I read this as a kid in the 90s and became very dissapointed there still weren't trips to the moon.

Basic information, easy for children to read, about the sun, moon and stars. Written in 1959, it isn't the most up to date info, but it's a good start.
