“This is an ingenious experiment that worked for Dr. Williscroft's own son. I genuinely hope that it works for your child, too, and that each new story in this series will enrich your child as much as they did his son. In fact, I sincerely hope that this experiment will prove to be very successful for all children!”

A Relativity Birthday Present is the first story in the captivating, educational and beautifully illustrated Starman Jones Series designed to give young readers an intuitive grasp of esoteric scientific concepts like Relativity. It teaches young readers about one of the amazing effects of Relativity.
Starman Jones and Spacepup are anxious to take Baby Billy on their adventurous trips from star to star in their starship, Willywinder. Billy, unfortunately, is too young, so Starman Jones devises a trip to the star Alpha Centauri. During the journey he and Spacepup will travel so fast that time slows down for them on Willywinder, while time progresses normally back on Earth for Baby Billy.
Ultimately, Starman Jones and Spacepup return to Earth nine years later on Billy's ninth birthday, but they have hardly aged at all. Billy has caught up with them, and can now accompany them on future star trips. It is the best birthday present Billy has ever had – a relativity birthday present.
