> The meeting moved on without taking any formal action. Atlantis’ debris strike would pose no roadblock for Endeavour’s mission—just as foam never had held up a flight in the past. However, NASA would make sure its paperwork was in order. The hazard report would be looked over to be certain its wording more precisely reflected the nature of the foam threat.

> NASA’s public affairs staff churned out dozens of fact sheets, color brochures, and feature stories touting the scientific value of the research. But it was a tough sell. The experiments seemed second-tier to many outside observers. It was not that any one experiment represented demonstrably bad science. But given the half-billion-dollar cost of a shuttle flight, critics argued the price tag far outweighed the potential benefits. Even some in the shuttle program privately questioned the value of Columbia’s research.

> Columbia carried 13 rats, eight garden orb weaver spiders, five silkworms and three cocoons, four Medaka fish eggs, three carpenter bees, 15 harvester ants and an assortment of fish, mostly because students wanted to see how they would behave when weightless. One student experiment later attracted potshots from critics. Called “Fun with Urine,” the idea was to test the feasibility of urine-based paint as a possible way to redecorate future spacecraft, and thus stave off depression, on long-duration voyages.

> Crater analyses, like most of Boeing’s other shuttle production and operations tasks, had been done for years at the company’s Huntington Beach office. But responsibility for that and many other shuttle operations officially had moved from California to Houston earlier that month in an efficiency and cost-cutting move. As a result, Boeing engineer Paul Parker, who had been trained on Crater but had used the program only twice before, was assigned to help perform the analysis. Despite his inexperience, he knew enough about Crater to have concerns. The foam block that hit Columbia was estimated to have a volume of 1,200 cubic inches. That was at least 400 times greater than the largest foam cylinders used in impact tests to develop Crater.

> NASA engineers decided to simply remove the ramps and to install electric heaters to prevent ice buildups. The massive fittings that anchor the two struts holding the nose of the shuttle to the external tank—fittings that used to be buried inside the foam ramps—will be fully exposed on all future flights

This photograph book, while not a comprehensive collection of the early Peace Corps years in South Korea, includes numerous contributors, most notably Ambassador Kathleen Stephens’ (under President Obama) photographs from the late 1960s. Because it includes color images from the years of rebuilding when Peace Corps volunteers were both welcomed and regarded with superstition in the rural countryside, the book is an interesting testament to a slice of time in South Korea.

This book is the presentation of material from a doctoral thesis that took a couple of decades to get out. While containing interesting ideas and hypotheses, it suffers greatly from the extremely inflated ego of the author, who presents mere hypotheses as fact, and merely notes a couple of times in the middle of long footnotes that the archaeologists and anthropologists don't agree with him. His sourcing is questionable, as much is derived from secondary sources, primarily books written for a lay audience. In addition, he appears to ignore a substantial portion of the scholarship on this issue, preferring to pick and choose a handful of sources that he can use to support his arguments, without engaging the arguments of other scholars that don't come to the same conclusions. The book is further marred by the author's puritanical insistance on using the exact Hebrew or Aramaic spelling of Biblical names, which is bad form in a book written for a general audience, as it becomes in-your-face promotion of the knowledge of the author, and does not serve to move the book along; in fact, it gets it bogged down in minutiae that might be appropriate in a doctoral thesis, but not in a general audience book that seeks to "correct" a lack: the fact that information on the origins of the Bible is unavailable to the ordinary lay person. That fact alone calls into question some of the premises of the author, as by the time this book was published, there were several other books on that topic, some of which he cites in his footnotes and bibliography. Another weakness is his logical fallacies; his initial premise was based on circular reasoning, and he mangles logic in several other places, as well, in one place even taking absence of evidence for evidence of presence! This book was clearly an ego-trip for the author, and that's unfortunate, because he has some interesting and thought-provoking ideas that could generate a great deal of valuable discussion if he wasn't so determined to be the smartest guy in the room.… (altro)
