The algae bloom is very Julia set-like.

Your flowers aren’t the only thing blooming this summer. Our Aqua satellite captured this stunning image of phytoplankton blooms in the North Sea. These plantlike organisms tend to be most abundant in late spring and early summer due to high levels of nutrients in the water and increasing sunlight. http://go.nasa.gov/1M80vyp #EarthRightNow

Funny workplace safety videos from the 1950's to today.  The sound effects in the first clip from Xerox are the best.

Love the word but admit nothing.
There are insults and there are compliments.
Then, there's this...

New cover photo is the work of my recently turned 15 year old student exploring the nature of repeating and not repeating decimals.

He was expecting it to be less work.  He was expecting me to give more hints.  I just asked more questions about his work and forced him to test his theories.  Because he doesn't like to be wrong, he keeps his guesses to himself so I'm obliged to pull molars without anesthesia.  

He had colored-coded factors nicely and the answer was right in front of his nose.  I kept my hand over my mouth and waited for him to see it.  For more than one session he would see by the look on my face that he was so close but that I still wouldn't just tell him.  When he got the pattern for which decimals always repeat and which don't, it was great!  Then, it didn't take long for him to figure out why that pattern worked.  

Nice work, Ben!

I throw away the whites and eat 3-4 yolks at a time, most of the time.  When I scramble them I separate eggs and add extra yolks.  I drive hubby nuts but I think it's one reason my numbers are far better than his.

EAT YOLKS!

You may find me at the Puddle of Accumulated Water or at Little Red Gate but never at Cholera Camp.

Set up my profile on wsj.com community.  There's no category for education, I guess because no educator would be interested in reading The Journal.

I'll go...as long as there are plenty of my favorite math books.

We rather fancy dipping our toes in the water and relaxing on this white sandy beach...

Romulus Whitaker (http://en.wikipedia.org/wiki/Romulus_Whitaker) has been searching for crocodiles at least 20 feet long (PBS Nature:Supersize Crocs).  He didn't find any in the PBS episode Supersize Croc , but this week he has his answer.
