Nice!
 
Today's #googledoodle  is fantastic! I like the ascending and descending chain conditions, as well as all the references to conserved quantities.

Probably everyone has heard this news, but just in case:

Very exciting, and, for some reason, mildly surprising.  
The ocean there is thought to extend to 10 times the depth of Earth's oceans

An opportunity to hear mathematicians talking about what it's really like to do research, including dispelling several myths, such as the persistent one that it helps to have mental problems. Vicky Neale is one of the other guests, and another one is the director of the recent film X+Y (which I haven't seen but which appears to promote that myth). Cedric has done a huge amount of this kind of thing in France -- it's great to have him doing some of it in the UK too. I hope the programme is available outside the UK but don't know how to check that.
On Start the Week Tom Sutcliffe finds out what goes on inside the mind of a mathematician. Cédric Villani explains the obsession and inspiration which led him to being awarded the Fields Medal, 'the mathematicians' Nobel Prize' in 2010. Zia Haider Rahman combines pure maths, investment banking and human rights in his exploration of how abstract theory can impact on real life. Vicky Neale reveals the beauty of prime numbers, while the director Mor...

NASA has confirmed that Dawn entered the orbit of the dwarf planet Ceres, making history twice over.

Ignore the inaccuracy of the headline.  The article itself is written by someone who actually knows what they're talking about

From the article:
"Sweet Briar was founded in 1901, and has operated as a women's liberal arts college throughout its history, known for small class sizes and close student-faculty interaction. The college is considered a pioneer in study abroad and operates a leading study abroad program in France. Sweet Briar's equestrian program is also nationally acclaimed."

Eeeek!

Long article, but, worthwhile.  Its description of the problem of teaching math in the US is, in my experience, dead on.  We know how mathematicians do math, and, we know that in other countries, learning math that way is how students best both learn and come to love math.  But changing US mathematical education is not a matter of simply changing  x's and o's.  Instead it would require an absolutely titanic cultural shift one that's beyond the scope of money or legislation, I'm afraid.
The Common Core should finally improve math education. The problem is that no one has taught the teachers how to teach it.

I've been paying a little more attention to teacher's postings about the difficulties in our educational system. This was a very informative article. Thanks for posting it.

Even though at my latitude the hypothesis that I'll see it fails at 2 sigma, I'm still staying up till midnight and driving out of town.  Who knows when I'll have another chance?
The OVATION Aurora Forecast Model shows the intensity and location of the aurora predicted for the time shown at the top of the map. This probability forecast is based on current solar wind conditions measured at L1, but using a fixed 30-minute delay time between L1 and Earth.

Heard this on NPR today.  While I don't agree with some of the manifestations of her teaching philosophy (the quadratic formula memorized using a song??)  the philosophy itself is sound:  Make learning fun, bring passion and energy to it, care about your kids (yes, kids, not students - although they are that, too).  It's some kind of crime that she's paid just 30,000/yr.  She'll most likely leave the profession in the next few years - as do all the capable energetic young people who commit themselves to this career.  Then, the same people who pay her only 30k will justify that salary generally, by saying there aren't good teachers.  These legislators are like arsonists who blame the buildings they burned down on inefficient fire departments.

Daylight Saving snuck up on me again, exactly like in this action thriller.
