Happy Pi Day, 3.14

Happy Pi Day.

Pi is the symbol for the ratio of the circumference of a circle to its diameter. It is approximately 22/7 and is usually calculated to 3 digits, 3.14. With the use of computers, Pi has been caculated to over 51 billion decimal places. Pi is an irrational number meaning it will continue infinitely without repeating. The symbol for pi, pi, was first used in 1737 by William Jones, but was popular after it was adopted by the Swiss mathematician Leonhard Euler in 1737.

Next up, Mole Day.

Gorton’s Law Redux

Back in February I cheekily proposed a new Internet adage called Gorton’s Law. It was an allusion to the more well-known Godwin’s Law and is the notion that in any discussion of sea life, no matter how rare, strange or repulsive, some knucklehead will quickly sour the conversation by asking how well it goes with lemon or butter. An addendum to this is that it will usually happen within the first 10 comments and that they might also propose some other condiment.

My intent was to highlight how prevalent the attitude is that sea life is there merely for us to “harverst.” That the primary purpose is for our consumption and not for any intrinsic value or ecological roles those flora and fauna may contain.

Deep-Sea News has now officially formulated this notion into an actual equation.

Gorton’s Measure states that the time for someone to ask “Can you eat?” when discussing a marine species is directly proportional to the rareness, strangeness, and repulsiveness of the species.

Gorton's Laws, Equation for Sea Life Trolling [154x65, 4K]where theta=time for someone to ask “Can you eat?”
t=total people in room
alpha=species’ rareness
sigma=species’ strangeness
delta=species’ repulsiveness

Gorton's Laws, Equation for Sea Life Trolling [162x35, 4K]This is related to Gorton’s Constant (Gamma) that states that the question “How well does it go with lemon and butter?” will occur at a very high percentage approaching infinity despite relative changes in audience size (n).

My thanks to Craig for working out the maths. Of course, now that it is officially formulated, I regret a little going for the more amusing Gorton’s Law and not the more eponymous Robertshaw’s Law. At least that way I would have been know for something. Oh well. :)

Minnesota Museums: Science StoryPacks & Science Buzz Blog

[via Informal Science Educators Network Listserv]

Reading PZ Myers, one gets the inkling that Minnesota is an anathema to science education. But these sites seem to be fighting that impression.

Over at the Minnesota Children’s Museum there is an interesting and economical idea for teaching science.

Science StoryPacks™ are backpacks filled with literature and fun science activities for students Pre–K – 5. They’re a great addition to educational settings: as a science book nook for students, a parent involvement activity, or a small group instruction. Shipping: Pick–up available at Minnesota Children’s Museum for free, or a shipping fee of $10 each way is charged for each kit.

And over at The Science Museum of Minnesota, they have a website called Science Buzz, which is a, “regularly updated community newsletter highlighting current science news, events, and findings.” One contributor has written an entry on the recent Humboldt squid invasion off the coast of California which has generated so much…buzz.

Teachers can browse the Buzz Blog by science standards.

UPDATE: Got in touch with Maija from the Science Museum of Minnesota. Their MathPacks website is www.smm.org/mathpacks. They have also published an article in Teaching Children Mathematics, the NCTM elementary journal:

Measuring Growth on a Museum Field Trip: Dinosaur Bones and Tree Cross Sections
The MathPacks program at the Science Museum of Minnesota provides students with in-depth understanding of real-world applications of mathematics and science. Students measure museum specimens and investigate ratios, patterns, and mapping while simulating the work of scientists.
