     Stephen Hawking's book A Brief History of Time was a huge commercial success. Its achievements in

bringing difficult scientific ideas to a wide audience are not so clear. Now the distinguished physicist has

teamed up with his daughter Lucy to produce a children's book designed to communicate contemporary

physics. Will it capture the attention of young minds and teach them some real science?Will it be boring and

over the heads of the prospective readers?

     George's Secret Key to the Universe is an adventure story complete with villains (反面人物) and hero and

is illustrated with enjoyable line-drawings. It involves a lost pig,a humorously portrayed (描写) intelligent

computer,school bulies and a trip through the Solar System. Didactic discussions on aspects of modern

physics,such as supernova explosions and black-hole physics are hung on this set-up.There are also fact boxes

on physics and astronomy,and some photographs of astronomical phenomena:planets,comets,galaxies (星系)

and so on. Overall, the book is a serious effort to convey facts and ideas in present day astronomy and

astrophysics,within a science-fiction adventure story.

     The mixture is great. Children love facts and adventure stories. The combination will catch their interest

and keep them occupied for hours. After ten minutes of leafing through the book,my granddaughter Ruby

was deeply absorbed and I had to promise to bring it back for her to read after I had completed my review.

Like any educational tool,it will succeed for some and not for others. I suppose there should be more of the

former.
