"Earth Revealed" is a geology video series that can be viewed online for free (for users in the U.S. and Canada). Sample video topics include plate tectonics, the sea floor, the earth's interior, earthquakes, and volcanoes. The site provides program descriptions for each of the 26 half hour videos and also includes links to related resources. (Produced by Annenberg Media).

Hasty induction is also called incomplete induction, sometimes called jumping to a conclusion. However, since no human being can ever hope to have in hand all the data concerning any large prohlem, any induction about the larger problems of the world runs the risk of being incomplete. But conclusions from incomplete data may later become justified by additional facts. For example, when Columbus sailed west, he had only very scanty facts on which to base his conclusion that he might find land in that direction. The outcome precludes our blaming him for his incomplete induction; instead we say, "How wonderful: what a brilliant intuition." Similarly, William Harvey, the discoverer of the circulation of the blood, announced that all animals come from an egg, or an ovum. We now know that he was right. But at that time (1651), nearly three hundred years ago, nobody had ever seen the ovum of any mammal. Harvey was just making a hasty but clever induction and happened to be right. In this case also, we commend him for his shrewd insight, his intelligent grasp of fundamentals. His induction was based on incomplete data, but turned out to be completely correct.

H.J.A. Berendsen (2005) PDF 56pp, 17MB This booklet was made for fluvial sedimentologists who want to get an overview of the Rhine-Meuse delta in one day. The present excursion guide has been completely revised for the International Conference on Fluvial Sedimentology (ICFS) in Delft (2005), and is mainly based on Berendsen & Stouthamer (2001).
