This Week's Letters

The author of The River responds to a letter from researchers whose work was discussed in his book. Science reported comments from several presidential candidates concerning the decision to eliminate evolution from Kansas' science curriculum requirements, but not comments from Bill Bradley: a reader passes those along. Another perspective on the book From Space to Earth is offered from a scientist who was at the heart of efforts to develop solar cells for the commercial market: "[John] Perlin's book tells the story of people who took an existing space technology and used it to improve the quality of life on Earth." Some clinical observations are offered by Oliver Sacks of the ability of patients with different mental impairments to conceive of other people's mental states. And aspects to be considered in proposals for worldwide ecosystem assessment are discussed.
