Corrections:
- Page 51 Figure 3.1 (a): Barberpoles (and thus bipole) were found by the M.I.T. group, according to Martin Gardner's Feb 1971 Mathematical Games column dvgrn 10/4: fixed
- Page 53 Line 13: "combinations and known objects" is possibly intended to be "combinations of known objects". Check the wording carefully, as I'm not entirely sure. dvgrn 10/4: yup, pretty sure that's just a typo -- fixed
- Page 54 Figure 3.7 (b): Roteightor RLE does not match image (wrong phase)
- Page 57 Line -1: Remove 96 from and add 93 to the list of oscillators that use caterer dvgrn 10/4: already fixed
- Page 58 Figure 3.15: The caterer on rattlesnake is not a combination of a finger and dot spark. In fact, finger sparks cannot typically interact with dot sparks as claimed. dvgrn 10/4: not sure I've fixed this completely -- here's what I tried: Finger sparks can be combined with either dot spark predecessors (as in (b)) or standard domino sparks (as in (c)), but thumb sparks are best paired with domino sparks (as in (a))
- Page 59 Line 17: "arrangements of small still lifes" -> "arrangements of still lifes and sparkers" dvgrn 10/4: fixed
- Page 59 Line -11: "as this twin" -> "as the twin" dvgrn 10/4: already fixed
- Page 61 Line 1: "dot sparker known whose spark" -> "dot sparker whose spark" dvgrn 10/4: fixed
- Page 61 Figure 3.23 (b): p24 T-tetromino hassler RLE does not match image (wrong phase) dvgrn 10/4: fixed
- Page 61 Line 14: The p4 sparker used in the p24 shuttle was not seen earlier, as claimed. dvgrn 10/4: added clarifying footnote
- Page 62 Figure 3.26: The tub-stabilized form of Eureka was not the first known pre-pulsar shuttle (see Lifeline vol. 11 pgs. 16-17) dvgrn 10/4: fixed
- Page 234 Line 1: "high period-guns" -> "high-period guns" dvgrn 10/4: fixed
- various locations: There are a few cases where "period-[n]" is written (where [n] is some specific number), when the standard in the text appears to be "period [n]". just search "period-" to find them. dvgrn 10/4: fixed in chapters 3, 5, 6, 7, 8
- Page 53 Figure 3.5: Maybe add note about discoverer (Bill Gosper, Sep 1971) dvgrn 10/4: added
- Page 53 Figure 3.6: Maybe add note about discoverer (Mark Niemiec, 1972) dvgrn 10/4: added
- Page 54 Line -2: Remove "simply", as it's redundant dvgrn 10/4: fixed
- Page 59 Figure 3.18: Remove "(with improvements to decrease their size by Matthias Merzenich)", as it's unnecessary detail and the improvements were essentially trivial dvgrn 10/4: removed
- Page 60-61 Figures 3.21, 3.22: The reactions described as pushing a T-tetromino "left by 2 cells and mirroring it", but this reaction is typically considered a "left by 3 cells" push. This could maybe be reworded, although it's not essential. dvgrn 10/4: added another clause
- Page 54 Figure 3.7 (e) Dinner table RLE does not match image (rotated 90 degrees) dvgrn 10/4: fixed
