As new industries developed all over the world, the need for power grew—and so did the worry. And then suddenly, in 1942, one of the greatest discoveries of all time was made. The atomic age was born and the perfect fuel was found.

Atomic energy can do things never before dreamed of. Atoms, without any fire, without any noise, can run a huge electricity plant. The atoms in one pound of fuel can keep the lights burning in your home for 1000 years!

Atoms can send a large ship back and forth across the ocean many times—on one small load of fuel!

Atoms can keep hamburger fresh for weeks without freezing!

Atoms can sometimes cure sick people!

Atoms can find leaks in pipes, and can test the rubber in a set of car tires!

Atoms, in many ways, can make life easier, healthier, and better for us.

What are these wonderful atoms, anyway? Let's find out.
