Nuclear Physics of Stars

1807–2007 Knowledge for Generations

Each generation has its unique needs and aspirations. When Charles Wiley first

opened his small printing shop in lower Manhattan in 1807, it was a generation

of boundless potential searching for an identity. And we were there, helping to

define a new American literary tradition. Over half a century later, in the midst

of the Second Industrial Revolution, it was a generation focused on building

the future. Once again, we were there, supplying the critical scientific, technical,

and engineering knowledge that helped frame the world. Throughout the 20th

Century, and into the new millennium, nations began to reach out beyond their

own borders and a new international community was born. Wiley was there, ex-

panding its operations around the world to enable a global exchange of ideas,

opinions, and know-how.

For 200 years, Wiley has been an integral part of each generation’s journey,

enabling the flow of information and understanding necessary to meet their

needs and fulfill their aspirations. Today, bold new technologies are changing

the way we live and learn. Wiley will be there, providing you the must-have

knowledge you need to imagine new worlds, new possibilities, and new oppor-

tunities.

Generations come and go, but you can always count on Wiley to provide you

the knowledge you need, when and where you need it!
