02/12/2012 — Another Permutation Day!

Today we celebrate our second Permutation Day of the year!  I call days like today permutation days because the digits of the day and month can be rearranged to form the year.

We enjoyed our first permutation day of 2012 just 21 days ago.  Exactly three weeks apart!  That seems unusual.  I also wonder “How close could two permutation days be?”

Celebrate Permutation Day by mixing things up!  Try doing things in a different order today.  Just remember, for some operations, order definitely matters!

GIF Animations of Simple Machines

World of Technology has several great GIF animations demonstrating some fundamental mechanics:

Seen at right is the radial engine.  The constant velocity joint is my favorite, but it’s also great to learn how a sewing machine really works!

Some great visualizations of interesting and intricate 3D geometry and engineering.

Career Advice for the Mathematics Student

There is a great set of videos from MathsCareers.org.uk that focus on mathematics in industry.  The videos speak to strong math students who have questions about finding careers that utilize their mathematical abilities.

The speakers are employers and recent graduates working in technical fields, and they offer a lot of clear, thoughtful advice.

The “Why are ‘Soft Skills’ Important?” segment is particularly great to see:  the speakers all stress how communcation, writing, presenting, and teamwork skills are crucial to success in technical fields.  In addition, the “Why are Maths Graduates Sought After?” segment really highlights what is fundamentally important in mathematics:  problem solving skills, thinking creatively, and the ability to break complex ideas down into simpler ones.  These skills are prized in every field and industry.

The best advice I saw throughout the videos is to start thinking early about what really interests you and explore all the options you can.  There’s more to math than just teaching and banking!
