I, the author, am incredibly excited about this third edition of “Analog Computing” as it shows that there is a growing interest in analog and hybrid computing, my favorite topics in life. 🙂 This edition contains a wealth of new material, including two new chapters on digital control units (→section 9) and autopatch systems (→section 11) as well as a new appendix containing a comprehensive description of the circuitry of THE ANALOG THING, a small educational computer which has been in widespr ead use for the last couple of years (→section A). The section on the LORENZ system (→section 8.8) has been completely rewritten with a thorough exposition of the scaling process. The section on the Caltech computer (→section 3.5) also has been considerably extended. Spelling is now according to American English, although all dates are in dd.mm.yyyy format. Apart from this the bibliography has been substantially expanded and now contains 1265 entries, including many additional application examples and in-depth sources. This book would not have been possible without the support of many friends, family members, and colleagues. First of all, I would like to thank my beloved wife RIKKA MITSAM for her patience and never ceasing support of my obsession with analog and hybrid computing. I am also greatly indebted to UTE SKAMBRAKS from DeGruyter – without her support there would have been no 3rd edition of this book at all. Dr. CHRIS GILES not only enthusiastically proofread this book but also made many invaluable suggestions and improvements which greatly enhanced the quality of the book. In addition to this he always had an open ear when I needed someone to discuss technical topics in depth. NICOLE MATJE, OLIVER BACH, STEFAN WOLFRUM, SHRISH ROY did a terrific proofreading job. I am also greatly indebted to DANIEL RUEPP who spotted and corrected many subtle and not so subtle mistakes, ranging from simple grammatical blunders and sign errors to outright mathematical sins. JOACHIM WAGNER worked wonders with many of the new pictures included in this 3rd edition, especially in cases where only very grainy, old pictures were available. I would also like to thank MARCO GUERINI for discussions on analog computing in general as well as for several historic papers he sent me. CHRISTOPHER HOWARD made me aware of a special form of servo function generators used in early flight simulators and even took detailed photos on my behalf of such devices. Dr. ANTON GSANDTNER sent me a wealth of information about the work done in hybrid computing at the TU Wien. DAG SPICER from the Computer History Museum in Moffett Field gave me access to detailed manuals for a very earlyR EAC system. Last but not least, I would like to thank Prof. Dr. OLIVIER BOURNEZ (École Polytechnique) for long and fruitful discussions on computational complexity and related fields. I would also like to thank BARBARA HOELZER-BECK, HELMUT HOELZER’s daughter, for her support and her incredible hospitality RIKKA and I experienced during a week-long visit a few years ago. She also granted the rights for →figure 3.18 showing her father working on the replica of his analog computer in the 1990s. Thanks ar e also due to Mrs. SHELLEY HOLLINGDRAKE and Dr. GRAHAM CLAYTON of the Society of Dyers and Colourists for the wonderful pictur e of COMIC (15.40) and the permission to use it in this bookJ.O HANNES FRITZSCHE took the author’s photo used on the book cover. The cover picture of this edition was taken by TIBOR FLORESTAN PLUTO and shows the me with my beloved Telefunken RA770 precision analog computer, built in 1966. The schematics shown in this book now appear in three different styles (not counting schematics and computer setups r eplicated from literature). The earliest ones, dating back to 1st edition from 2009, were mostly drawn with xfig, a rather basic X-windows vector graphic program. Later schematics added in the 2nd edition were drawn using Eagle, a CAD program once in rather widespread use. Things have changed a lot since then and schematics added in this 3rd edition were drawn using KiCAD, a cross-platform open source electronics design automation suite.
