Synopsis: Using a white dwarf star fragment, physicist, Ray Palmer, has developed a lens which will shrink inanimate objects when ultra-violet light is sent through the lens. However, Ray has been unable to perfect the process because the shrunken objects always explode withing minutes.
Visiting an underground cavern on a nature hike with his girlfriend Jean Loring and a nature club, Ray becomes trapped inside with the group during a cave-in. Exploring the cave, Ray locates only one tiny opening. He uses the sunlight, beamed through the lens to shrink himself to tiny size. Then using the diamond from his ring, enlarges the opening until people can safely pass through.
Worried that he might explode, Ray hurries back to the lens and enlarges himself back to normal. He is surprised that he did not explode and hypothesizes the cave water may have altered the properties of the lens. When he returns to his lab, objects still explode when shrunk, leaving Ray to conclude that his own body possesses a mysterious force, enabling him to survive the shrinking process.Synopsis uses material derived from dcindexes.com.

Synopsis: David Clinton, an ex-con, becomes obsessed with time. He invents several gadgets using time as a theme, then he begins a series of robberies as Chronos, the time-thief. Clinton uses a clock shop in Ivy Town as a cover for his illegal activities. When Ray Palmer comes in and tells Clinton about an atomic clock at the university, the crook goes after it.
Chronos crosses paths with Palmer at the university, then the Atom shows up to fight. After escaping, Chronos sets a trap for the Atom whom he suspects is Ray Palmer. When Atom arrives at his shop, Chronos traps him, but the tiny titan escapes, defeats Chronos, and protects his dual identity.
Synopsis: Ray Palmer visits another scientist, Professor Alpheus V. Hyatt, at his lab. Hyatt has developed the Time Pool, a hole in time-space created by light. The professor is able to send objects into the hole and bring them back, much like fishing. The hole is too small for people to travel in however.
Atom is able to fit into the Time Pool, so he rides the professor?s fishing line into the past. Disoriented by the experience, Atom takes a nap inside a lamp. The lamp belongs to an arab boy, Hassan. Atom emerges and is thought to be a genie. He helps the boy locate a family treasure and protects it from thieves. Then Atom makes a return trip through the Time Pool, bringing a gold dinar with him as proof of his trip into the past.
This is the first Time Pool story. The Time Pool, invented by Professor Hyatt, is a tiny hole of white light into which small objects can placed to travel backwards in time. The Time Pool becomes a regular method for the Atom to time travel and have adventures in the past.
