ARCHIMEDES' PRINCIPLE
An object is buoyed up with a force equal to the weight of the liquid it displaces. This is known as Archimedes' Principle. As an example, suppose you pushed an empty (and sealed) one-liter milk
carton under the water in your bath tub. Since the carton must displace (push aside) one liter of water... | {"url":"http://www.exploratorium.edu/xref/phenomena/archimedes'_principle.html","timestamp":"2014-04-18T03:00:14Z","content_type":null,"content_length":"2736","record_id":"<urn:uuid:56e24058-7e17-48b3-80a3-5a42dfe0f3e1>","cc-path":"CC-MAIN-2014-15/segments/1397609532480.36/warc/CC-MAIN-20140416005212-00176-ip-10-147-4-... |

A very beginner question about indexing: let x be an array where n =
len(x). I would like to create a view y of x such that:
y[i] = x[i:i+m,...] for each i and a fixed m << n
so I can do things like numpy.cov(y).

Finding the middle group in a SES.
I'm in the situation that I have a short exact sequence of groups 1->A->B->C->1. I know that A and C are Z and Z[2] respectively and I know that B is torsion-free. Is this enough information to find
B?
