If authors manage to write something, there are still hazards to be negotiated like proof-readers (e.g. for the C3–C4 book deciding photon should be changed to proton), copy-editors, type-setters (as were), publishers who
trash books, distributors, book sellers, editors who have problems, libraries and political correctness. So it is very nice, when enthusiasm starts to flag, that authors are sometimes offered kind encouragement. Now I feel this website refreshed, my enthusiasm rekindled and immensely grateful to my colleagues in photosynthesis for honoring me in this way.” With this mindset, David devoted time to making his major works available in digital form; in conjunction with the GSK872 in vitro ISPR they are hosted by
Hansatech Instruments (see http://www.hansatech-instruments.com/david_walker.htm). Early on, he believed there was a role for digital books in facilitating retrieval of buy CBL0137 information from “a library which never closes.” He recognized that texts which depend heavily on cited references, “books” in Portable Document Format (PDF) which contain embedded hyperlinks, can guide and facilitate rapid retrieval of reliable information from the Internet. David’s books were also greatly enhanced by colorful illustrations drawn by his son, Richard (e.g. Fig. 3; also see Web resources at http://www.photosynthesisresearch.org). Fig. 3 A Richard Walker, David’s son. Richard was an illustrator and collaborator for some of David’s published works. Three illustrations are shown; B See web resources at: http://www.photosynthesisresearch.org; C from Walker (1992a); D from Walker (1987) A favorite activity of David’s around Christmas time was to go
to pubs for singing of traditional Yorkshire Christmas carols, which he thoroughly enjoyed. Thus, maybe it’s not surprising that another outreach effort to promote science to the Sulfite dehydrogenase general public was his development of a series of multiple choice questions which were placed on designed beer mats (coasters) for pubs. In 2000, he got a Millennium award to distribute 90,000 of them! (Fig. 2, also see http://www.hansatech-instruments.com/pub_understanding.htm). David also took pleasure in creating high-resolution pictures within leaves based on the distribution of starch: see starch prints at the above web site. David wrote extensively about sources of energy, photosynthesis, biofuels, plants and man, the greenhouse effect, and global climate change in his books “Energy, Plants and Man,” (Walker 1992a) and “Global Climate Change” (Walker 2002d). In his last paper, “Biofuels—for better or worse?” (Walker 2010), David was concerned about some of the unrealistic benefits, or claims, being made about biofuels and their potential to contribute to road and air transport without full scientific vetting.
