studied pictures of the Shroud of Turin and noticed that the weave in the area where the sample had been taken for carbon dating was an ever so slightly different weave than the rest of the shroud. (Carbon testing had determined that the shroud was not 2,000 years old but from medieval times.) She also did research into cloth repair. Well, nobody would listen as she was just this DIYCSI housewife w/out proper credentials. But she refused to take no for an answer; and finally, some mucky mucks took a look. Lo and behold, *they* discovered that the sample cut from the edge of the cloth was part of a medieval patch. Why do we do it? To observe, question, and seek answers is in man's nature.
