A Note on Web Sources

Where a book is cited, I have generally provided a link to the appropriate Amazon page. However, this may, on occasion, point to a different edition of the book to that cited in the text -- the original is held in the author's collection, and the link is provided as a service to the reader.

I also provide, where available, links to online versions of journal articles. Many journals prevent full text access without a subscription, so the full paper will not always be available.

Where a reference is cited on multiple occasions (eg. Artificial Life), only the first instance is linked.

Paperback Edition Notes

I have made a few minor changes to the references for the paperback edition (published, in the UK at least, on June 14 2007). These include updating web links, replacing "web-only" citations with rather more long-lived sources, and replacing all Wikipedia references with "traditional" (rather more rigorous) sources. Whilst Wikipedia might be a useful resource for initial research, I felt that using it as a primary source was perhaps inappropriate for a book with at least some scholarly aspirations.

Where a reference has changed, I have (for the time being) included the original after the new reference. These old citations will eventually be removed.

Prologue

  1. It was only after I'd written this prologue that I discovered a book that essentially shares the same title as this one. James P. Hogan's novel The Genesis Machine even opens with a remarkably similar scene, although any parallels observed here are completely unintentional, and, if anything, the creation of my fictional introduction owes more to Blood Music.

  3. In a private email, Greg Bear confirmed my theory that the character was named in homage to Stanislaw Ulam, a stellar mathematician and one of the founders of the field of computational biology. He also pointed out that `Vergil I. Ulam' is an anagram of `I am Gulliver'. The double-helix derivation of `Neal Mendal' is left as an exercise to the reader.

  23. You may actually be more familiar with the notion of an infinite loop than you think. When a computer crashes or freezes, this is often the result of the program spiralling downwards into an infinite loop. This may be caused by a hardware fault (for example, the computer repeatedly looking for a device that is not plugged in), user errors or sometimes just bad programming. The program is, for all intents and purposes, still running, which is why you often need to press CTRL-ALT-DELETE to interrupt its execution and restart the system.
  24. It is easy to simulate a Turing Machine on a standard computer (ignoring the requirement for unbounded memory). The mathematician Karl Scherrer actually built a Turing Machine in 1986, using construction kits and ball bearings to represent data. Its last known location was in the entrance to the Department of Computer Science at the University of Heidelberg, Germany.

However, this account has been disputed, with sources at Apple claiming that the rainbow is a reference to Isaac Newton's work on optics. A President of Apple Products, Jean-Louis Gassee, has commented: "One of the deep mysteries to me is our logo, the symbol of lust and knowledge, bitten into, all crossed with colors of the rainbow in the wrong order. You couldn't dream of a more appropriate logo: lust, knowledge, hope, and anarchy." (Apple Confidential: The Real Story of Apple Computer, Inc, Owen W. Linzmayer, No Starch Press, 1999). Regardless of the involvement of Apple, biographer Andrew Hodges said it best during his 1998 oration to Turing at the unveiling of a Blue Plaque on his birthplace; "...time has partly revealed his secret song of innocence and experience, and given significance to the veiled image of the poisoned apple.".

  29. The average chip contained 5.5 million components in 1995, a matrix of roughly 2.35 x 2.35 million. A standard postage stamp is roughly 2cm = 0.02m per side. 2.35 million (components) x 0.02m = 47,000m per side = 47km per side = 2,209 sq km. The area of Snowdonia National Park is 2,210 sq km, or roughly a tenth of the size of Wales (or a third of the size of Delaware, for readers in the USA).
  30. The average chip contains 256 million components (a conservative estimate), giving a matrix of 16 million by 16 million. Given 0.02m per stamp side, 16 million (components) x 0.02m = 320,000m per side = 320km per side = 102,400 sq km. According to the CIA Factbook at http://www.cia.gov/cia/publications/factbook/, the area of Iceland is roughly 103,000 sq km, or five times the size of Wales (or roughly the size of Virginia).

  32. Richard Feynman made this point in typical fashion when describing his role as a school textbook reviewer for the California State Board of Education. `For example there was a book that started out with four pictures: first there was a wind-up toy; then there was an automobile; then there was a boy riding a bicycle; then there was something else. And underneath each picture it said `What makes it go?' ... I turned the page. The answer was, for the wind-up toy, `Energy makes it go.' ... Now that doesn't mean anything. Suppose it's `Wakalixes.' That's the general principle: `Wakalixes makes it go.' There's no knowledge coming in. The child doesn't learn anything; it's just a word!' (Richard P.

The subtitle of this book was the subject of much editor-author discussion, after my publisher argued that, to the general reader, this research does seem like totally new science. I agreed to let it stand, on the condition that I was permitted to make my own position clear (that it isn't really a new science, and is more of a novel conjunction of existing scientific disciplines).

  45. A version of the Kevin Bacon game also exists for mathematicians, replacing the actor with Paul Erdos, the late mathematician who was famously prolific in his collaborations. Erdos is assigned the value 0; if you co-authored a paper with Erdos before his death, you get the value 1. If you co-author with a co-author of Erdos you are assigned the value 2, and so on. A low number is considered prestigious by some mathematicians. See http://www.oakland.edu/enp/ for more details.

  17. Or, if you prefer, `soccer' ball. A typical eukaryotic cell might be 20 micrometers in diameter. The nucleus is roughly 6 micrometers across. A standard football is 22 cm in diameter. If we round this down to 20 cm, we can see that a football is 10,000 times the size of a cell. Scaling the nucleus up by the same factor, we arrive at a diameter of 6 cm, which is roughly the size of a satsuma.

  33. When a newly-sequenced gene sequence is lodged in the public databases, it is given a `name' by which it may be referred in the literature. These names are often informal - one gene, for example, when knocked out in fruitflies, caused them to develop pointy projections on their body, so the gene was named hedgehog. A similar gene was subsequently found and named Sonic hedgehog, after the game character, and this name now regularly appears in the titles and abstracts of serious scientific papers. Recently, the manufacturers of the Pokemon toy took out legal action to prevent gene researchers infringing their trademark with a gene name. Other, more serious problems may arise - as Ken Maclean points out in a letter to Nature, the innocent `humour' of gene names may be lost in translation to patients, when `people facing serious illness are told that they or their child have a mutation in a gene such as Sonic hedgehog, Slug or Pokemon' (Nature 439, 266, January 19, 2006).
