"Doctor WHO" is not a name, but a question to which we're
still learning the answer. We do know that the being who calls
himself the Doctor is a Time Lord from the planet Gallifrey.
Hundreds of years old, clownish, brilliant and wise, he travels
through time and space in his TARDIS, a ship, which looks like
a British Police call box on the outside but is almost infinitely
large within. Currently in his tenth regenerated form and together
with companions from Earth and other planets, the Doctor wanders
the cosmos, fighting oppression, outwitting nasty aliens, maniacal
computers, killer robots and an evil Time Lord called the "Master".
He makes the Universe a much more exciting and interesting place.
