P. C. W. Davies

Paul Davies is a an excellent science writer, bringing fresh perspective to historical and new science but what makes this book particularly interesting is the insight we get from firsthand access to the research on the subject.

Biology is still a strange science, exceptions outweigh the rule when you try to make any statement, there is a lack of fundamental principles to follow and even being able to effect a measurement reliably is completely non trivial.

However this state is unlikely to remain like this forever and the direction of a new way to identify principles in biological sciences will include information as a metric and evolutionary “optionality”.

Paul Davies in this book brings something new evem to people that feel they know contemporary biological methods.

On the down side the book is less accessible than other texts by the author ans requires attentive reading.… (more)

I found this short book a delightful read. Davies gives us a brief overview of how current physics theory, in particular relativity and quantum mechanics, can allow the possibility for time travel, both to the future and, more surprisingly, to the past. He also briefly describes the kinds of paradoxes that can result from time travel to the past and how these paradoxes might be resolved. This brief introduction motivates me to seek more detailed treatments in the popularized science genre and the more technical physics research literature.… (more)
