This is a group of blogs on the universe and other light topics. I post a new one monthly on the 1st Wednesday. Sometimes I post a series on a subject weekly for a few weeks.

Just hover your mouse over the heading "Pencils - Physics and Philosophy Blogs" and a drop down menu will appear showing the different threads. The first one explains the title "Pencils".

If you want to be notified when a new blog is posted, follow me on Twitter: @hughmoffatt. I promise not to flood your inbox.

Let me know your thoughts!
