Read more about LISA!
In addition to the various online resources (see LISA on the web), there are a number of good books that will give you further information about the search for gravitational waves, and about LISA's role in that endeavour.
A good starting point is
- Marcia Bartusiak, Einstein's Unfinished Symphony. Berkley Books, 2003.
Bartusiak tells the story of gravitational wave research and the people behind it - from the pioneers of the 1960s to the current detectors and future projects like LISA.
If you want to learn more about the objects that LISA is meant to study, such as black holes, and if you would like to find out more about the physics behind gravitational waves, then you will find a veritable treasure trove in
- Kip Thorne, Black Holes and Time Warps. Einstein's Outrageous Legacy. W. W. Norton, 1995.
Of course, in physics, the real fun starts when you begin to dig a little deeper. True - to fully understand what black holes and gravitational waves are about, you would need a thorough grounding in advanced mathematics. But it's amazing how much further, compared to prose science writing, even elementary maths of the kind taught in school can take you. So if you still remember what a square root looks like, have a look at
- Bernard Schutz, Gravity from the Ground Up. Cambridge University Press 2004.
Schutz takes the reader on a tour from Newton's to Einstein's gravity, from ordinary stars like our sun to black holes, and from our own cosmic neighbourhood to the universe as a whole, using no more than simple high-school mathematics.
