Notes on Teaching delivers utterly relevant guidance, lucid explanatory commentary, and helpful examples that will help anyone become a better teacher. Like its siblings in the Notes On series (Notes on Directing and Notes on Cooking), the book's clear, accessible, and practical insights into the art and craft of teaching invoke the spirit of Strunk & White's The Elements of Style and Sun Tsu's The Art of War, giving its audience the information they need in the way they want it: brief, efficient, direct. The notes are designed to provoke strong reactions--either in agreement or dissent--that will guide anyone who teaches to acknowledge, test, and debate their own beliefs. By turns provocative, funny, and unerringly blunt (#166 \"Steer clear of the grumblers\"), the authors understand that HOW the information is delivered is as valuable as the information itself. The book's afterword is by Taylor Mali, a teacher and one of the most well-known poets to have emerged from the poetry slam movement, famous for his poem, \"What Teachers Make.\" Notes on Teaching is endorsed by: Wendy Kopp, Founder, Teach for America. Geoffrey Canada, President and CEO of Harlem Children's Zone. Michael Thompson, PhD., co-author of Raising Cain: Protecting the Emotional Lives of Boys and The Pressured Child. Jack Covert, Founder and President of 800CEOREAD and co-author of The 100 Best Business Books of All Time. Marc Tucker, President, National Center on Education and the Economy.

IS THE hydrogen economy, popularized by Jeremy Rifkin's 2002 book of the same name, all washed up? Fuel-cell technology is still expensive and there is still no widespread hydrogen production and refuelling infrastructure. For hydrogen supporters, the ultimate future is replacing declining fossil fuel reserves with a mix of alternative energies, using hydrogen as the principal energy vector for energy storage and transportation. Proponents say that this system would help reduce climatechanging pollutants, improve energy independence, and even boost our economy. It is difficult to argue against the goals of such an initiative, though sceptics may rightfully ask, \"Where is the hydrogen?\" The news from Europe is equally promising. European initiatives include over 30 ongoing hydrogen/fuel-cell projects totalling over euro100 million (about $142 million CAN), and over 20 hydrogen-refuelling stations. Germany has set the European standard, representing half of the refuelling stations and a third of the projects. Even developing nations are moving in the right direction. As part of its preparations for the 2008 Olympics, China is investing heavily in fuel-cell buses and hydrogen infrastructure to improve urban air quality.

Polymer electrolyte membrane fuel cells (PEMFCs) exhibit encouraging potential as an enabling technology for the Hydrogen Economy. Currently an important barrier to commercialization is the cost associated with existing PEMFC materials; this project’s goal was to investigate alternative materials for PEMFC bipolar plates. Conductive thermoplastic materials offer the promise of low density, low cost processing, and inexpensive resins, and were the focus of material development for PEMFC bipolar plate applications. In order to develop a thermoplastic bipolar plate this study utilized the combination of a low cost injection moldable commodity polymer resin, and low cost carbon materials as conductive fillers. The materials selected and tested included; a polypropylene copolymer; acetylene carbon black; Vulcan carbon black; and short carbon fiber. The components were combined in a twin screw extruder and injection molded into samples for testing. The result was a spectrum of composite samples with a range of filler loadings from 0 to 60 wt% and varying filler type ratios. Synergy between the different carbon types was achieved which led to better physical properties, specifically conductivity. The novel blends produced were tested for electrical conductivity, mechanical properties, rheology, microscopy, and actual plates were made and tested in a single cell PEMFC. These trials enabled discussion around the feasibility of the materials with respect to processability, cost, and performance (both in the fuel cell and in potential applications). The most significant results were measured using a composite blend with 54 wt% filler loading and a 1:1:1 filler ratio. Mechanical results achieved 68% and 100% of the industry targets for tensile and flexural strength, respectively. Tensile strength attained 27.7 MPa and flexural strength measured 82.8 MPa. Electrical conductivity results for the same samples varied between the two methods of measurement used. Using a fuel cell industry recommended procedure 2.2 S/cm was achieved and using a four point ASTM measurement technique 12.0 S/cm was reported. These values represent 3% to 12% of the industry target. Actual 16 cm2 fuel cell plates were produced, fuel cell hardware constructed and assembled, and the power output was found to be 51% relative to graphite plates. Thermoplastic bipolar plates for PEMFCs made of composite materials is promising, but optimum filler loading that balances all properties is still required in order to achieve conductivity targets. Nevertheless this study has demonstrated that conductive thermoplastic bipolar plates can be produced via injection molding.

He says the problem with teachers is, \"What's a kid going to learn from someone who decided his or her best option in life was to become a teacher?\" He reminds the other dinner guests that it's true what they say about teachers: Those who can, do; those who can't, teach. I make kids sit through 40 minutes of study hall in absolute silence. No, you may not work in groups. No, you may not ask a question. Why won't I let you get a drink of water? Because you're not thirsty, you're bored, that's why.

(CNN) -- Editor's Note: Taylor Mali spent nine years in the classroom teaching everything from English and history to math and SAT test preparation. He is an advocate for teachers and speaks at education conferences and teachers' workshops. His book, \"What Teachers Make: In Praise of the Greatest Job in the World,\" will be released on March 29. \"Empty pockets never held anyone back. Only empty heads and empty hearts can do that.\"-- Norman Vincent Peale, American minister and author On one level, my new book, \"What Teachers Make: In Praise of the Greatest Job in the World,\" is an explication and expansion in prose of a piece of writing that first came to me in the form of poetry. At a New Year's Eve party in 1997, a young lawyer managed to insult me and the entire teaching profession by essentially saying that no person dumb enough to want to be a teacher should be allowed to actually become a teacher. The poem I wrote in the weeks that followed, \"What Teachers Make,\" is the response I wish I had been smart enough to give to the lawyer at the party.

\"It's quality, not quantity,\" \"In small packages good things come.\" my poetry doesn't resonate. Oh no.
