Lisa Randall is hugely gifted... Full of passion and jaw-dropping facts... Fascinating

An impressive study...essential reading for anyone interested in science

Dazzling ideas... Read this book today to understand the science of tomorrow

Science has a battle for hearts and minds on its hands... How good it feels to have Lisa Randall's unusual blend of top flight science, clarity, and charm on our side

In this fascinating book, Lisa Randall, professor of theoretical physics at Harvard, explains the experimental research at the LHC and the theories that try to anticipate what they will find

Her touch is light and deft; these are not topics that come easily to life, and they are unavoidably complex at times, but Randall's calm authority and clarity of explanation are exemplary

Lisa Randall does a great job of explaining to the non-physicist the basic scientific approaches of modern physics and what the latest experiments might reveal. This is a must read to appreciate what is coming in our future.

I didn't think it was possible to write a complex, detailed look at the world of physics that the non-scientist could understand, but then Lisa Randall wrote this amazing, insightful and engaging book and proved me wrong.

Lisa Randall is the rarest rarity--a theoretical physics genius who can write and talk to the rest of us in ways we both understand and enjoy. This book takes the nonspecialist as close as theyll ever get to the inner workings of the cosmos.

Written with dry wit and ice-cool clarity...Knocking on Heaven's Door is a book that anyone at all interested in science must read. This is surely the science book of the year.

Randell...tries to illuminate something of the underlying themes driving current scientific thinking.

His honesty and integrity are legendary and this shines through in his book... Nothing, nothing was too small or unimportant to escape his attention. They all had their place in the wonderful balance of nature... He didn't just make wildlife films grow up. He made the best there ever was and will ever be and told his stories with a humour and innuendo and so poignantly that it brought the other living creatures that we live with on our planet level with us, and gave them a status and dignity that they'd never had before...a must for, well, everyone

Alan, almost single-handedly in my opinion, made wildlife films grow up
