Several reviews here give the reader the chance to under- stand the basic theoretical concept of gravitational lensing and to obtain an overview of observational work. The present state of the field and latest results are given in a large number of specialized papers. Anextensive source and subject index make these proceedings valuable also as areference book for all researchers active in the field. 410 0$aLecture Notes in Physics,$x0075-8450 ;$v406 606 $aGravitation 606 $aObservations, Astronomical 606 $aAstronomy?Observations 606 $aAstrophysics 606 $aGeophysics 606 $aDifferential geometry 606 $aMathematical physics 606 $aClassical and Quantum Gravitation, Relativity Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P19070 606 $aAstronomy, Observations and Techniques$3https://scigraph.springernature.com/ontologies/product-market-codes/P22014 606 $aAstrophysics and Astroparticles$3https://scigraph.springernature.com/ontologies/product-market-codes/P22022 606 $aGeophysics/Geodesy$3https://scigraph.springernature.com/ontologies/product-market-codes/G18009 606 $aDifferential Geometry$3https://scigraph.springernature.com/ontologies/product-market-codes/M21022 606 $aTheoretical, Mathematical and Computational Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19005 615 0$aGravitation. 615 0$aObservations, Astronomical. 615 0$aAstronomy?Observations. 615 0$aAstrophysics. 615 0$aGeophysics. 615 0$aDifferential geometry. 615 0$aMathematical physics. 615 14$aClassical and Quantum Gravitation, Relativity Theory. 615 24$aAstronomy, Observations and Techniques. 615 24$aAstrophysics and Astroparticles. 615 24$aGeophysics/Geodesy. 615 24$aDifferential Geometry. 615 24$aTheoretical, Mathematical and Computational Physics. 676 $a523.1/12 702 $aKayser$b Rainer$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aSchramm$b Thomas$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aNieser$b Lars$4edt$4http://id.loc.gov/vocabulary/relators/edt 906 $aBOOK 912 $a9910257435803321 996 $aGravitational lenses$91478062 997 $aUNINA LEADER 02038nam 2200589Ia 450 001 9910453175603321 005 20200520144314.0 010 $a1-281-93428-3 010 $a9786611934286 010 $a981-279-351-8 035 $a(CKB)1000000000538191 035 $a(StDuBDS)AH24685073 035 $a(SSID)ssj0000276228 035 $a(PQKBManifestationID)11221593 035 $a(PQKBTitleCode)TC0000276228 035 $a(PQKBWorkID)10223832 035 $a(PQKB)10366872 035 $a(MiAaPQ)EBC1681462 035 $a(WSP)00001771 035 $a(Au-PeEL)EBL1681462 035 $a(CaPaEBR)ebr10255615 035 $a(CaONFJC)MIL193428 035 $a(OCoLC)815752297 035 $a(EXLCZ)991000000000538191 100 $a20080722d2008 uy 0 101 0 $aeng 135 $aur||||||||||| 181 $ctxt 182 $cc 183 $acr 200 10$aZany, zeal, zeat and zing$b[electronic resource] $ethe z way to happiness /$fZaibun 210 $aSingapore ;$aNew Jersey $cWorld Scientific$dc2008 215 $aix, 105 p 300 $aBibliographic Level Mode of Issuance: Monograph 311 $a981-279-350-X 320 $aIncludes bibliographical references (p. 97-101) and index. 327 $aHappiness Is a Serious Matter; What Is Happiness; Be Zany; Apply Zeal; Have Zest; Put Zing into Your Life. 330 $aProvides a brief history of happiness and motivates readers to apply strategies related to happiness in their day-to-day life.
