Mandala mosaic on our magnetic wall





It finally arrived!

So happy to get my fractiles! Got them on our magnetic wall quickly and easily.




The geometry is pretty ingenious. There are three different pieces, each with four sides. There are six different possible angles, 1/14, 2/14, 3/14, 4/14, 5/14, and 6/14, thus providing sevenfold rotational symmetry (per package description).

Did you feel the earthquake?

For those of us who live in earthquake country, this question comes up in conversation with regularity. Often, smaller earthquakes don't make it to the headlines so we're often left debating whether it really happened.

Fortunately, the USGS has gathered up local, recent earthquake data for California and Nevada at: http://quake.usgs.gov/recenteqs/

A few games, winding down for the holidays

Now that Halloween has come and gone, the holiday season has officially started. My blogging will be slowing down drastically, so I'd like to recommend a few favorite games that are free online to entertain you.

1. Coloretto

A great family card game for 3-5 players, this is a family favorite both at home and online. Even the five year old is getting proficient at it. Great for teaching strategy, since everyone's cards are face up, and there is no reading involved.





2. Set

A game for any number of players, this is a card matching game where you find a 'set' of 3 cards among the 12 on the table that fit certain characteristics. Try the Set Daily Puzzle.


3. Sudoku

It's a fad that's likely come and gone, but it is still a wonderful logical deduction puzzle. My favorite online version is at websudoku.

For more information about board and card games in general, I highly recommend BoardGameGeek. Not only do they rank thousands of games by user votes, they also have descriptions, photos, and shopping links to help you fill out your shopping/wish list.

Happy Holidays, whatever you may celebrate. Enjoy the time off work if you can!

Carnegie Mellon University computer scientists have developed an interactive, online game featuring a little fish named Phil that can teach people how to better recognize and avoid email "phishing" and other Internet scams.
Researchers gave people pre and post tests after a 15 minute game session, and determined people learned more from the game than they did spending the time reading about, or taking other tutorials about the subject.

More information about Anti-Phishing Phil is at: http://cups.cs.cmu.edu/antiphishing_phil/

Or, go here to play the game. (They are also offering a raffle for a $100 amazon.com gift card for participants who leave an email, and participate in a post test 1 week later.)

The Heinlein Archives, now digitally available

Robert A. Heinlein is best known as one of the 'Big 3' of science fiction writers (along with Isaac Asimov, and Arthur C. Clarke). More about his life can be found here.

His bibliography can be found here.


Located at http://www.heinleinarchives.net/upload/, this collection:
...presents digital copies of the entire collections of Robert A. and Virginia Heinlein in downloadable form for research and academic purposes. Heinlein’s OPUS manuscripts is the first complete collection presented. These manuscript files include Heinlein’s files of all his published works with his notes, research, early drafts and edits of manuscripts, to the final published form. These files provide both a look at Heinlein’s creative process and add insights into his intent and the meaning in his stories.
It's like having access to the director's cut, to better grok the man and his stories. For a fee, of course. TANSTAAFL.

Learn about your brain: the Video Game

The video gives you an idea of the graphics, as well as the target audience (citations are annoyingly targeted at parents).

From Corante:
Neuromatrix is an NIH-funded video game developed to teach children about their brains.

In the game, you play a secret agent infiltrating a top-secret neuroscience research facility. Your mission: to track down and root out the Nanobots that have invaded the brains of the scientists there. If you fail, the Nanobots and the secret entity that spawned them will take over the Earth, reprogramming the human brain into docile submission.

The game was developed by Morphonix and is recommended for kids age 10-15.

RFIDs on your mobile phone to pay for stuff on campus

From TUV News:
Pennsylvania's Slippery Rock University is to unveil a 13.56-MHz RFID tag which can be attached to pupils' mobile phones and allow them to pay for services and goods at the institution, reports RFID Journal.
No need to carry money on campus, just your cell phone. And, you'll have to memorize another PIN number to complete any transactions.

More details from engadget:
"...which will "allow them to pay for everything from laundry and copier services to movies and groceries in the surrounding town of Slippery Rock...Of course, high rollers should be aware that their guardians can log in at any time and view their purchasing habits, so we'd be careful before pulling out the long face and car trouble story. The cards will reportedly cost around $1 apiece, but will be "available for free" to all of the SU students."
As long as they don't start using this to track high school students' attendance, it seems like a useful convenience.

CDC Disease Cards

That's right, the Center for Disease Control has created a set of collectible cards of infectious disesases.

Originally designed for middle school students, these cards have already sold out. Fortunately, you can freely download and print these .pdf files from the CDC website.

Charles Darwin's letters available online

Pic: A letter from Darwin to his friend Joseph Hooker (right), written whilst he was recuperating in the lull between writing On the Origin of Species and its publication. On the left is a reply from Hooker.

The complete works of Charles Darwin is available online at: http://darwin-online.org.uk/

Apparently, handwritten letters were recently added to the Darwin Correspondence Project at: http://darwin1.caret.cam.ac.uk/

It's a pretty big collection:

Darwin was a prolific letter writer, exchanging correspondence with nearly 2,000 people during his lifetime (1809-1882). Nearly 14,500 of his letters are known to exist, with the biggest collection residing in Cambridge.
Makes me wonder how Darwin would have felt if he knew that so many of his personal letters would someday be publicly available to anyone with an internet connection. Seems an ironic devolution of privacy.
The article below mentions the variety of his letters, including some family conversations about his personal hygiene. I wonder if that's as embarrassing as baby bath pictures?

Exploratorium Exhibit Index

Brings back many happy memories.

Here's a nice reference list of exhibits. Some also have posted explanations. http://www.exploratorium.edu/xref/exhibits/exhibit_index.html

Or, for the more experienced scientist, an index by phenomenon.

Lastly, for those who prefer to roam around, an area index.

The key to understanding the big picture? Sleep

"Science Daily — Memorizing a series of facts is one thing, understanding the big picture is quite another. Now a new study demonstrates that relational memory -- the ability to make logical "big picture" inferences from disparate pieces of information -- is dependent on taking a break from studies and learning, and even more important, getting a good night's sleep. "
Researchers did a study where they had students learn a relationship pattern between objects. Students were then broken down into 4 groups: a group that took the test 2o minutes later, a group that took the test 12 hours later but without sleep, a group that took the test 12 hours later and got sleep, and a group that took the test 24 hours later with a full night's sleep. The students that took the test 20 minutes later did the worst.

The researchers speculate:
"This strongly implies that sleep is actively engaged in the cognitive processing of our memories," notes Ellenbogen. "Knowledge appears to expand both over time and with sleep...Concludes Walker, "These findings point to an important benefit [of sleep] that we had not previously considered. Sleep not only strengthens a person's individual memories, it appears to actually knit them together and help realize how they are associated with one another. And this may, in fact, turn out to be the primary goal of sleep: You go to bed with pieces of the memory puzzle, and awaken with the jigsaw completed."

Robots to learn emotions and socially appropriate responses

Dr. Lola Canamero with her robotsOh my....

"Feelix Growing is a research project involving six countries, and 25 roboticists, developmental psychologists and neuroscientists.
Co-ordinator Dr Lola Canamero said the aim was to build robots that "learn from humans and respond in a socially and emotionally appropriate manner". "

They start with basic robot hardware, and are focussing on software that learns, via neural networks. The article breaks the tasks up into three parts.

1. Sensory input - "Tactile feedback and emotional feedback through positive reinforcement, such as kind words, nice behaviour or helping the robot do something if it is stuck." Another article jokes about whacking them on the head with a newspaper if they are naughty.

2. Detect expressions - "The robots will get the feedback from simple vision cameras, audio, contact sensors, and sensors that can work out the distance between the machine and the humans. " Then they will use neural networks to learn and intergrate the data.

3. Imprinted behaviors - They start by having the robot imprint to the first object they see, much like Lorenz and his geese. ""We have a prototype of a robot that follows people around and can adapt to the way humans interact with it. "It follows closer or further away depending on how the human feels about it." "We are focusing on emotions relevant to a baby robot that has to grow and help human with every day life ".

Makes me think of the movie AI. Definitely worth seeing. Futuristic Pinocchio story, excellently done.

Montessori for college students?

A nice study that supports giving college kids freedom to learn and think, instead of cookbook lab experiments provided better test scores, and more objective thinkers.

"Science Daily — Give college students less instruction and more freedom to think for themselves in laboratory classes, and the result may be a four-fold increase in their test scores."

Here's the breakdown: "Roughly 300 students, all taking an introductory biology course for science majors, were in each group. The first group used what Rissing calls the “cookbook method” – they followed step-by-step instructions on how to carry out the experiment and display their results. These students were provided with a standard, prepared enzyme solution.
The second group of students had to prepare their own enzyme solutions from a piece of raw turnip. They were also given more freedom to think through their approach to the same experiment, and were encouraged to use critical thinking and hands-on discovery to come up with their approach. "

Results: ..."(23 percent) in the “cookbook” group answered the question correctly. But 83 percent of the students who developed their own approach gave the right answer".

The goal is to increase scientific literacy for the masses, and this is a good start.
