{"product_id":"geophysical-inverse-theory-9780691036342","title":"Geophysical Inverse Theory","description":"\u003cp\u003eIn many physical sciences  the most natural description of a system is with a function of position or time. In principle  infinitely many numbers are needed to specify that function  but in practice only finitely many measurements can be made. Inverse theory concerns the mathematical techniques that enable researchers to use the available information to build a model of the unknown system or to determine its essential properties. In Geophysical Inverse Theory  Robert Parker provides a systematic development of inverse theory at the graduate and professional level that emphasizes a rigorous yet practical solution of inverse problems  with examples from experimental observations in geomagnetism  seismology  gravity  electromagnetic sounding  and interpolation. Although illustrated with examples from geophysics  this book has broad implications for researchers in applied disciplines from materials science and engineering to astrophysics  oceanography  and meteorology.  Parkers approach is to avoid artificial statistical constructs and to emphasize instead the reasonable assumptions researchers must make to reduce the ambiguity that inevitably arises in complex problems. The structure of the book follows a natural division in the subject into linear theory  in which the measured quantities are linear functionals of the unknown models  and nonlinear theory  which covers all other systems but is not nearly so well understood. The book covers model selection as well as techniques for drawing firm conclusions about the earth independent of any particular model.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":45965893566517,"sku":"ByrdShop_0691036349","price":114.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9780691036342.jpg?v=1788372312","url":"https:\/\/atxbooks.com\/products\/geophysical-inverse-theory-9780691036342","provider":"ATX Books","version":"1.0","type":"link"}
