Regarding researchers' boycotting Elsevier journals, a mathematician comments on the publisher's high priced mathematics titles as well as apparent lack of peer review.
Review of 1999 book on cosmology demonstrating universal phenomena contingent on six numbers. "Forget those 1,000 things you need to do before you die, the 10 commandments and seven deadly sins. Concentrate instead on six impossible things that, as the White Queen advised Alice, you must try to believe before breakfast. Without them there would be no galaxies of stars, no chemistry, no people, no books and no breakfast."

(abstract only, full text requires subscription or purchase) "We analyze the logs of an online mathematics game tournament, played simultaneously by thousands of students. Nearly 10,000 students, coming from 356 schools from all regions in Chile, registered to the fourth tournament instance. The children play in teams of 12 students from the same class, and send their personal bets to a central server every 2 minutes. Each competition lasts about one clock hour and takes place within school hours. Students are pre-registered and trained by their school teacher. The teacher is responsible for reviewing curriculum contents useful for improving performance at the game and coaches students participating in trial tournaments taking place a few weeks before the national tournament. All bets are recorded in a database that enables us to analyze later the sequence of bets made by each student. Using cluster analysis with this information, we have identified three types of players, each with a well-defined strategy. "
"a weekly activity for students of grades 8 to 12 and post-secondary students. The activities are something beyond classroom traditional in-class and curriculum-based learning. Presentations by Circle members or by invited mathematicians and scientists, discussion about specific topics and solving math problems, puzzles and games; review math/science history and preparation for maths contests and Olympiads are the main activities in the GMC."
Review of Conway's Mathematical Connections, written for undergraduate mathematics courses, with the aim that instructors help students find connections across branches of math. Two similar books for undergraduates, recently published, are mentioned as well.
2013 memoir by Edward Frenkel chronicling his journey from the Soviet Union (where he was prevented from studying at Moscow State University) to teaching at Harvard and University of California, and the role and centrality of mathematics in his life. Subtitled the Heart of Hidden Reality
Over the last ten months since I launched iPadApps4School.com I have reviewed a lot of mathematics apps that are appropriate for elementary school students. These are the ten that have been the most popular over the last ten months (based on total clicks and shares through social media).
Relying on a comprehensive review of the research, Mathematics Learning in Early Childhood lays out the critical areas that should be the focus of young children's early mathematics education, explores the extent to which they are currently being incorporated in early childhood settings, and identifies the changes needed to improve the quality of mathematics experiences for young children.
In this lesson, students learn how to measure the area of the tire footprint on a car and to find air pressure using a tire gauge. Students then find the weight of the car using their fraction multiplication skills.
Learning Objectives
Students will:
Estimate weight of a large object
Use a ruler and a tire gauge to take measurements
Collect and record data
Review square units of measure
Calculate area by multiplying fractions
Materials
Strips of poster board
Ruler
Tire gauge
How Much Does a Car Weigh? Activity Sheet
Computer with internet connection
Car
Instructional Plan
In preparation for this lesson, place a car in a safe lcation for the students to measure the tire footprints and pressure. In case of bad weather, find a covered location. Be sure to measure the tire footprint and the pressure (in PSI) of each tire ahead of time, so that you will be able check the accuracy of students' measurements. Also, check the accuracy of your calculation by comparing to it to the weight of the car listed on the sticker inside the driver's door or in the vehicle manual.
By the end of the day, data may change because air has leaked out of the tires while students were using the tire gauge. For safety, check the tires before driving home.
A workshop scheduled in Berkeley, California, Feburary14-16, 2011. "The workshop will discuss what is important and unique to the publishing
of mathematical research articles and how we can best ensure that
publishing practices support peer reviewed research in the long term.
Much of the current discussion is taking place between funders and
publishers, including learned societies, but not directly with
mathematicians. A second goal is to see if we can find a consensus of
opinion on what is important about journal publishing to mathematicians,
that is, where the balance lies between the desire for profits from
publishing and the broader dissemination of research."
