Ever since the TARDIS was first revealed in 1963, Doctor Who has presented a bewildering array
of alien technology and gadgetry. Human scientific knowledge can do nothing to explain the
mysteries of the astonishing devices and phenomena that the Doctor takes for granted.

This is the first publication devoted to the incredible ideas that the series has made its own.
Highlights include a comprehensive guide to the sonic screwdriver, the secrets of the Time Lords
and the weaponry of the Doctor’s most dangerous enemies.
