His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.I was traveling and lecturing throughout much of the Lenten season and had the misfortune to pick up a bug along the way, which put me in bed for two weeks and forced me, for the first time ever, to cancel one of my lectures (in Ottawa, Canada).Fortunately, my good friend John Iannone graciously took my place at the last minute.The size of the sample then required, however, was ~500cm, which would clearly have resulted in an unacceptable amount of damage, and it was not until the development in the 1970s of small gas-counters and accelerator-mass-spectrometry techniques (AMS), requiring samples of only a few square centimetres, that radiocarbon dating of the shroud became a real possibility. The shroud was separated from the backing cloth along its bottom left-hand edge and a strip (~10 mm x 70 mm) was cut from just above the place where a sample was previously removed in 1973 for examination.Check here for important announcements and other Shroud of Turin Website news.Now a new find has produced a breakthrough in the investigation.
