Jabberwocky

`Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves, 

And the mome raths outgrabe.


"Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!"

He took his vorpal sword in hand:
Long time the manxome foe he sought --
So rested he by the Tumtum tree,
And stood awhile in thought.

And, as in uffish thought he stood,
The Jabberwock, with eyes of flame,
Came whiffling through the tulgey wood,
And burbled as it came!

One, two! One, two! And through and through
The vorpal blade went snicker-snack!
He left it dead, and with its head
He went galumphing back.

"And, has thou slain the Jabberwock?
Come to my arms, my beamish boy!
O frabjous day! Callooh! Callay!'
He chortled in his joy.

`Twas brillig, and the slithy toves
Did gyre and gimble in the wabe;
All mimsy were the borogoves,

And the mome raths outgrabe.

No 'Around the Internet' section this month - I've unfortunately not really had the time to blog at all recently.


Instead here is some 'Pumpkin Art' by artist Ray Villafane to enjoy:

The Ig Nobel Prizes 2010

The Ig Nobel prizes for 2010 were awarded last Thursday (30th September) at Harvard's Sanders Theatre.

For those who are unaware of them the Ig Nobels are a somewhat less serious version of the Nobel prizes, to quote Improbable Research (the people who award the prizes):

"The Ig Nobel Prizes honor achievements that first make people laugh, and then make them think. The prizes are intended to celebrate the unusual, honor the imaginative — and spur people's interest in science, medicine, and technology."

The winners were:

ENGINEERING PRIZE:
Karina Acevedo-Whitehouse and Agnes Rocha-Gosselin of the Zoological Society of London, UK, and Diane Gendron of Instituto Politecnico Nacional, Baja California Sur, Mexico, for perfecting a method to collect whale snot, using a remote-control helicopter.

MEDICINE PRIZE:
Simon Rietveld of the University of Amsterdam, The Netherlands, and Ilja van Beest of Tilburg University, The Netherlands, for discovering that symptoms of asthma can be treated with a roller-coaster ride.

TRANSPORTATION PLANNING PRIZE:
Toshiyuki Nakagaki, Atsushi Tero, Seiji Takagi, Tetsu Saigusa, Kentaro Ito, Kenji Yumiki, Ryo Kobayashi of Japan, and Dan Bebber, Mark Fricker of the UK, for using slime mold to determine the optimal routes for railroad tracks.

PHYSICS PRIZE:
Lianne Parkin, Sheila Williams, and Patricia Priest of the University of Otago, New Zealand, for demonstrating that, on icy footpaths in wintertime, people slip and fall less often if they wear socks on the outside of their shoes.

PEACE PRIZE:
Richard Stephens, John Atkins, and Andrew Kingston of Keele University, UK, for confirming the widely held belief that swearing relieves pain.

PUBLIC HEALTH PRIZE:
Manuel Barbeito, Charles Mathews, and Larry Taylor of the Industrial Health and Safety Office, Fort Detrick, Maryland, USA, for determining by experiment that microbes cling to bearded scientists.

ECONOMICS PRIZE:
The executives and directors of Goldman Sachs, AIG, Lehman Brothers, Bear Stearns, Merrill Lynch, and Magnetar for creating and promoting new ways to invest money — ways that maximize financial gain and minimize financial risk for the world economy, or for a portion thereof.

CHEMISTRY PRIZE:
Eric Adams of MIT, Scott Socolofsky of Texas A&M University, Stephen Masutani of the University of Hawaii, and BP, for disproving the old belief that oil and water don't mix.

MANAGEMENT PRIZE:
Alessandro Pluchino, Andrea Rapisarda, and Cesare Garofalo of the University of Catania, Italy, for demonstrating mathematically that organizations would become more efficient if they promoted people at random.

BIOLOGY PRIZE:
Libiao Zhang, Min Tan, Guangjian Zhu, Jianping Ye, Tiyu Hong, Shanyi Zhou, and Shuyi Zhang of China, and Gareth Jones of the University of Bristol, UK, for scientifically documenting fellatio in fruit bats.

Fun with Probabilities

This post by Stephen Landsburg on his Big Questions blog has got me thinking about probabilites.

I'd like to post my own (well, plagarised from here) problem to readers:

Three poker chips are in a cup. One is marked with a BLUE dot on each side, another with a RED dot on each side, and the third has a BLUE dot on one side and a RED dot on the other. So there is one blue/blue chip, one red/red chip, and one blue/red chip.

Without looking, you take out one chip, and lay it on the table.

1. Suppose the up-side turns out to be BLUE? What is the chance that the down-side will also be BLUE?

2. What if the up-side is RED? What is the chance that the down-side will also be RED?

3. Before you see how the chip has fallen, what is the chance that it has the same color dot on both sides?

4. Suppose you answered 1/2 in response to Questions 1 & 2. That would mean that whichever the up color of the chip, the chance is 50/50 that the color on the down side is the same. But if at Question 3 you said that chance is 2/3, aren't you contradicting yourself?

If you follow the link to the paper the question comes from you'll get an explanation of the correct answer.  This is essentially a rephrasing of the more familiar Monty Hall problem.
