Question: Who wrote the book that Eureka appeared in?

<P0-S0> Pan Lei () (1646 – 1708) was a Qing dynasty scholar. <P0-S1>  He wrote the prefaces for a number of works that appeared in his time. <P0-S2>  In the preface to writer Qu Dajun's book "Guangdong Xinyu", widely regarded as a valuable source on the economic and social conditions of Guangdong in 1700, Pan wrote about the beauty, natural resources, and unique history of East Guangdong. <P0-S3>  Pan was also involved in the study of mathematics. <P0-S4>  In the preface to Mei Wending's "Fangchenglun", a treatise on linear algebra written in 1690, he wrote: <SEP> <P1-S0> Reaching for the Invisible God: What Can We Expect to Find? <P1-S1>  is a book written by Evangelical Christian writer Philip Yancey and published by Zondervan in September 2000. <P1-S2>  The popularity of Yancey's 1997 book "What's So Amazing About Grace? <P1-S3> " helped boost the sales of "Reaching for the Invisible God" to the point that it appeared on religion bestseller lists immediately upon publication. <P1-S4>  Within a month, Zondervan reported sales of 94,000 copies. <P1-S5>  While preparing to write the book, Yancey asked several people how they knew that their trust in Jesus had changed their lives, and one Christian radio host responded, "I have no trouble believing God is good. <P1-S6>  My question is more, what good is he? <P1-S7>  ... I cry out to God for help, and it's hard to know just how he answers". <P1-S8>  "Reaching for the Invisible God" includes discussion of Yancey's bad experiences of growing up in a very judgmental church, a theme that he had previously discussed in "The Jesus I Never Knew" and "What's So Amazing About Grace?" <P1-S9>  and later returned to in "Soul Survivor". <P1-S10>  In November 2000, "Reaching for the Invisible God" became the first print book to be released as an e-book by Zondervan, appearing on Microsoft Reader. <P1-S11>  The book received the 2001 "Christianity Today" Book Award in the spirituality category. <P1-S12>  A "Topeka Capital-Journal" review called "Reaching for the Invisible God" "another accessible book from Yancey on a theologically complex subject for those who believe in God, and those who aren't sure if they can". <P1-S13>  David Crumm of the "Lincoln Journal Star" wrote a review of the book and said that Yancey's honesty about his own personal pursuit of God is remarkable. <P1-S14>  In a 2001 review in "The Christian Century", Peter Marty writes that Yancey "succeeds brilliantly [in] tell[ing] the truth about the Christian life 'without overselling it'". <SEP> <P2-S0>  It was published on June 18, 1908 and reunites Dorothy with the humbug Wizard from "The Wonderful Wizard of Oz" (1900). <P2-S1> Dorothy and the Wizard in Oz is the fourth book set in the Land of Oz written by L. Frank Baum and illustrated by John R.
