The weekly routine

My two big new projects for 2012 are Numberphile and Deep Sky Videos.

I'm being flexible about upload dates so the videos can react to what happens in the world (and space).

But as a general rule I am trying to upload Deep Sky Videos on Mondays and Thursdays.

Numberphile films go up on Tuesdays and Fridays.

Here are last week's additions...

MONDAY - The Elliptical Galaxy M105


TUESDAY - Why the fraction 3/4 is important in biology


THURSDAY - The Reflection Nebula M78


FRIDAY - Why the number one is NOT prime
