Gravitational Flexion
Gravitational Flexion (pronounced "flecks-shun" for the uninitiated, and yes, it is a real word) is a new technique for measuring 2nd order gravitational lensing signals in background galaxies and
radio lobes.
Unlike shear, flexion directly probes variations of the potential field.

Hi All,
I am a beginner to OpenGL programming. I am stuck with a problem. I will
explain it with a simple example.
I wanted to draw a tilted V using two lines and some rotations. I wanted
to do in the following way.

Perfect Numbers
When playing taxman, there are numbers like 6 where the taxman will tie your first move. Another number where this happens is 28 (try it out). When a number equals the sum of its proper factors, it
is called a "perfect number".
Perfect numbers are surprisingly few and far between, and mathematical knowl... | {"url":"http://davidbau.com/archives/2008/12/11/perfect_numbers.html","timestamp":"2014-04-18T05:43:33Z","content_type":null,"content_length":"9227","record_id":"<urn:uuid:a98bfb24-bcca-4b3c-8744-79df58baaeef>","cc-path":"CC-MAIN-2014-15/segments/1398223203235.2/warc/CC-MAIN-20140423032003-00206-ip-10-147-4-33.ec2.inte... |

Thank you for this amazingly informative article. I hardly like to mention that, in equation (4) above, where you have given the equations of the foci of an ellipse, the second set of co-ordinates
should refer to F2, and not F3 as listed.

What are the higher homotopy groups of Spec Z ?
up vote 25 down vote favorite
The homotopy groups of the étale topos of a scheme were defined by Artin and Mazur. Are these known for Spec Z? Certainly π[1] is trivial because Spec Z has no unramified étale covers, but what is
known about the higher homotopy groups?
