More in 3D Printing

As has been previous noted, I am very exci3D printed fluteted about the burgeoning era of 3-D Printing.  Here is another amazing example of where this technology is heading:  a computer printed concert-quality flute!

After the 15-hour printing process with an Objet Connex500, a printer that applies several different raw materials, all that reamined was some minor assembly.  And, of course, some test-flauting!  Check out the video to the quality of the flute for yourself.

This is Jeopardy!

jeopardy boardIn the past we tested the prowess of our supercomputers by teaching them to play chess and pitting them against humanity’s greatest players.  Today we test our supercomputers by filling them up with trivia, arming them with a quick trigger finger, and pitting them against America’s greatest Jeopardy! contestants.

On February 14th, 15th, and 16th, IBM’s Watson will compete against Jeopardy! superstars Ken Jennings and Brad Rutter.

This should be a lot of fun.  I can’t wait to see what Watson’s Daily Double strategy is!

2010: The Year in Facebook Statistics

facebook logoThis is a cool summary of 2010 in terms of Facebook-related statistics:

With 500 million (!) users, Facebook is rapidly becoming a source of seemingly limitless data about how people live and interact in modern society.  Some of the highlights:

  • Nearly 61 million people changed their relationship status to in a relationship / engaged / married
  • Nearly 43 million people changed their relationship status to single
  • Over 6000 pages were liked every second!  (Speaking of which, how about liking my page?)

The potential applications of analysis of this data, both good and bad, are mind blowing.  As previously noted, people have used Facebook data to identify peak break-up times and to predict someone’s sexual orientation based on their various connections and activity.

Math Photo: (Sine) Waves on the Beach

While on vacation, I passed some of my time looking for math on the beach, and I saw a sine wave creeping up the shore.

sine wave in nature

I thought I might be looking too hard for something mathematical, thereby seeing things that weren’t really there.  Thankfully, Geogebra is well-equipped to justify my observations.

Or perhaps it’s more accurate to say that Geogebra helps enable my obsessions.

Shocking Mathematical Results

 

Welectroshock therapyhen it comes out that I’m a math person, the most common response from people I meet is “I was never very good at math“.  After a lifetime of struggling to find the appropriate response, I finally have something positive and proactive to say:  go get yourself some electroshock therapy.

According to a recent study, running a mild electric current through the brain seems to temporarily increase mathematical ability.   Apparently the study involved teaching the subjects a new numeration system (could it have been octomatics?) and testing their ability to organize those symbols before and after electrical stimulation of the parietal lobe.

In addition to slightly increasing mathematical ability and potentially treating dyscalculia, there is hope that such electrical stimulation could improve other brain function, as well.

Now, how can I bring this revolutionary technique into my classroom?
