It's Square Root Day......Party on!

Math fans celebrate Square Root Day on 3-3-09

REDWOOD CITY, Calif. - Dust off the slide rules and recharge the calculators. Square Root Day is upon us.

The math-buffs' holiday, which only occurs nine times each century, falls on Tuesday - 3/3/09 (for the mathematically challenged, three is the square root of nine).

Transcendental meditation would have left you feeling better the next day ... just in time for Julius Caesar Day.

But serially, folks, here's a useful pi page from a math site:

Will they hold a special Pi day in 6 years?
by Bill Osler / March 3, 2009 6:54 AM PST

I wonder if anybody celebrated Pi day in 1592? But then I'm not even sure which calendar system was dominant then or whether anybody recorded dates in m/d/y format back then.

FWIW: I'm not sure very many folks outside the US would make the connection between March 14 and Pi. Aren't we one of the few users of the m/d/y format? Everywhere I've visited outside the US people have preferred d/m/y.

Math Club on campus will do it up.

Chalking formulae on the sidewalks et al.

Let's see: 3/14/(20)15
Hey! Pretty good!

When did Gregory mess with the calendar? If before 1592 then your other one goes out the window. Happy

BTW in my link I didn't see one excellent approximation of pi: 22/7. I tell my kids about it because it's the best one to use in problems involving other fractions. Try it yourself- it doesn't fail until the thousandths digit.

Used to be my party piece in High School reciting Pi
by Ziks511 / March 11, 2009 7:42 PM PDT

to 20 decimal places, also the speed of light though not to so many places. What I remember of Pi is 3.1415962. As for C it's 186,288.1 mpsec. My son got me a T-shirt from Think Geek.com that has the sign for Pi marked on the shirt with little tiny numbers, a couple of thousand of them to make the Pi about a foot tall. I finally get a shirt with a lot of Pi and now my eyes won't let me read it.

ThinkGeek- highly recommended.

I just discovered it, and have had plenty free entertainment just reading the product descriptions. I just may buy the wi-fi signal-strength T-shirt.

But wait! There's more!
by drpruner / March 3, 2009 3:43 PM PST

Just saw a campus poster advertising a performance of Calculus: The Musical !
This "comic 'review' of the concepts and history of calculus" was co-written by a high school math teacher as an aid.
'Calculus is used in rocket science but need not be "rocket science"' we're assured.

Pi, you say? Here we have our pi in the sky!
No more smarmy stagings of Our Town- this is real drama! Newton vs. Liebniz! The battle of the Difference Engines! Infinitesimal concepts presented!
Soon to be a major [incremental] motion picture starring Brad Pitt as Newton, F. Murray Abraham as Liebniz, and Penelope Cruz as the Woman in Red!

Since pi day is Saturday,
by drpruner / March 9, 2009 6:46 PM PDT

the Math club (see post above) is celebrating on its regular meeting day. That's tomorrow, Woden's Day.
From noon to 1:15 they'll have "festivities" and free pie !
You are all invited!

According to the formula printed at the bottom of the poster, pi are squared, but you'll have to come see for yourselves.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
