Very awesome trip last week. The Baltimore chapter of the Women’s Transportation Seminar (WTS) took the students who have been participating all year in WTS’s Transportation You mentoring program to the airport!
Transportation You is all about increasing the number of girls interested in transportation, engineering, and other STEM careers. At Baltimore-Washington International Thurgood Marshall Airport (BWI) we learned about aviation, the infrastructure of the airport itself, and some of the jobs performed by women in those areas.
Introductions at BWI
Of course, I knew it was going to be a great trip when we walked in and saw all these trusses in the ceiling!
Trusses Trusses Everywhere!
Among many interesting parts of the visit, they took us up to the Operations Control room.

And then out onto the roof!

A fun day it was!
Once again, Pi Day has arrived!
As you probably know, pi (π) is a mathematical constant found in circles and throughout mathematics! Since pi’s decimal expansion starts off 3.14…, and today’s date is 3/14, we celebrate pi and all things mathematical on this day!

My Top Pi Ways to Celebrate Pi Day
1. Share pi (and pie) with friends
2. Read and learn more about pi
3. Contemplate the wonder of the universe and mathematics’ role within it

Pieces of Pi
Related to #1 and #2 above, here are a few cool tidbits about pi and pi day:
- Check out this piem, that is, a poem where the number of letters in each word yields the sequence of pi’s digits. Though I’ve discussed several of these before (most notably, Poe, E. Near a Raven), I had not run across this century-old piem before this week!
- Relatedly, here’s a statistical analysis on the probability of writing piems or other pilish phrases by accident!
- If you’re a fan of mathematical art, check out this Numberphile video explaining some of the art I’ve featured in today’s post, and also this gallery of mathy art from this winter’s Joint Mathematics Meetings in Baltimore!
- Challenge yourself with some pi sudoku puzzles from Brainfreeze from years past! Or with the online Pi Day Challenge!
- Listen to a new recording of the sound of pi (this one uses pi in base 12 to match up with the chromatic scale)!
- Read this article about pi’s normality (whether each digit or combination of digits appears equally in the decimal expansion of pi) from this month’s American Mathematical Monthly!
- Today I had my students throw toothpicks at some lines (the Buffon’s Needle experiment, described here and here; the connection to pi is explained here). Fun!
- Some other ways to celebrate can be found in my (Pi Day – 2) post here!
- Thanks to the math department at my alma mater, Williams College, for featuring this post on their website!
I cannot believe it’s been 10 years since my first pi day expansive email that set up (or continued) a crazy propaganda war between the mathematical constants pi and e. (Going back even further, by my count I’ve been celebrating pi day in some form or another for almost 18 years now!) Just about each year since 2004 I have sent out my annual missive on Pi Day, by email and/or by blog (a few years when March was especially busy for me, I sent out messages on other pi-related days). A list can be found in yesterday’s pre-pi-day post here.
Have a great Pi Day today, and many more!
3.13 – that’s nothing special – but it’s almost Pi Day!
In case you can’t read it, it says “Plenty of Pi to go around” and has digits of pi arranged in a circle around the outside! Image and pie by Pippi, from this website.
Enjoy this picture of a pi pie, and get ready for tomorrow’s celebration!
To tide you over, here are some of my past posts concerning pi:
As you know, Pi Day is nigh! This Friday, March 14th (3/14), is the great and glorious day of pi (π=3.14…)!
Not sure what to do on Pi Day?

It’s approximately pi days until Pi Day here on the east coast (i.e. a little more than three days)!

I leave you for today with a little quip I just thought of, written in pilish (count the number of letters in each word):
Day o’ math I await: celebrate pi!
Pi Day is on its way!
That’s right, Pi Day (3/14) will be this Friday, so I hereby declare a happy Pi Week to all!

The contract was ratified. Boo.
Unfortunately, it seems there was very low turnout. Only about 1000 teachers voted today, compared to the nearly 3000 who voted in November 2010, and out of a total union membership of approximately 6000.
Perhaps this was due to the sudden and rushed way this contract and the vote were sprung upon us only a week ago. Perhaps to a feeling of disenfranchisement of teachers who were not consulted in the writing of the contract which was negotiated behind closed doors. Or perhaps due to the hours of voting, 7:30am-5:30pm, at only six different sites, which is pretty much synchronous with the school day for many hardworking teachers.
Here’s what I wrote over 3 years ago at my last contract vote:
Voting today was supposed to go from 7am to 6pm. I got to my voting location this morning at 7:05 but went to the wrong side of the building/campus. At 7:15 I parked my car in the right place, got out, greeted a number of teachers from my school who were standing in line, and found out voting hadn’t yet begun; they were still setting up inside. This was outrageous, since they had had weeks to prepare and they knew that teachers had to get to their jobs and teach a full work day. No leave or early-release day had been given, and 7:30-6 are pretty much my usual working hours!
I heard similar stories of polls opening late this morning. I made it to a voting station today at about 5:00pm. I was the only voting teacher there (along with about 5-6 poll staff). Everything went smoothly for me this time. I just wish more teachers had voted: it might have made the difference in being able to re-negotiate a better contract instead of being stuck with this very flawed one.
