Number Treasury 3
Investigations, Facts and Conjectures About More than 100 Number Families
Written as a resource for both teachers and students, this enlarged third edition of Number Treasury is designed to guide readers through the steps that will help them to think critically, to provide explanations and to formulate conjectures about different families of positive integers. Its 137 exercises and 28 'investigations', at three levels of difficulty, cover such intriguing topics as magic squares, palindromic numbers and twin primes. Detailed solutions are provided at the back of the book.
The Telomerase Revolution
The Enzyme That Holds the Key to Human Aging... and Will Soon Lead to Longer, Healthier Lives
Why does growing old lead to so many forms of illness? Recent advances in the study of human cells have revealed that the key to answering this question lies in the telomeres – the tips of chromosomes – which shorten every time a cell reproduces. As he explains these insights, Fossel highlights the ability of the enzyme telomerase to re-lengthen the telomeres and discusses its potential as a means of treating age-related diseases such as Alzheimer’s.
The Graphene Revolution
The Weird Science of the Ultrathin
The strongest substance ever discovered, a better conductor than any metal and able to act as a molecular sieve to purify water, graphene is set to revolutionize technology. This guide explores the properties and potential uses of this remarkable new material.
The Reality Frame
Relativity and Our Place in the Universe
By building and populating a virtual universe, Clegg demonstrates that reality is not a system of immovable absolutes; instead, the ever-shifting world of relativity is what provides the frame of reference that allows us to understand both the universe and humanity’s place within it.
The Equations of Life
The Hidden Rules Shaping Evolution
Professor Charles Cockell argues that evolution and natural selection have always been constrained by basic physical laws, from an atomic level to the animal realm. For instance, there are sound scientific reasons why creatures can’t evolve with wheels instead of legs, and why carbon-based cells are ideal for trapping energy, so life on Earth is far more understandable and predictable than we might imagine.
