One Week Till Book Release, and a Twitter Autograph Game!
posted on July 26th, 2012

In celebration of the release of my new geometry book on August 2nd, I’ve decided to have a little autograph game! In this game, the 10 winners will win autographed nameplates to put in their copies of Girls Get Curves: Geometry Takes Shape. And I’ll personally sign them to you or a different name – a niece? Daughter? Friend?

Here’s how it works:

For 24 hours, from the evening of August 2nduntil the evening of August 3rd, I will randomly tweet 10 questions – mostly requiring use of the book (for example: What do the letters in the diagram on p.--- of Girls Get Curves spell?), and maybe one or two questions that don’t require you to have the book – but they’ll be geometry questions.  J Each time, the FIRST person to tweet me back will get a brief follow and DM from me so I can get the address and name that the autograph goes to!

The book will be available in stores on August 2nd, but if you pre-order it on Amazon, they should deliver it by August 2nd, too – and in time for the game to start. (But most of the questions will happen on August 3rd.)

Win an autographed nameplate sticker to put in your copy of GGC!

Thanks for reading about my nifty little game, and I hope you’ll join me on Twitter next Thursday and Friday to play!

The common rail system prototype was developed in the late 1960s by Robert Huber of Switzerland and the technology further developed by Dr. Marco Ganser at the Swiss Federal Institute of Technology in Zurich, later of Ganser-Hydromag AG (est.1995) in Ober?geri.
The first successful usage in a production vehicle began in Japan by the mid-1990s. Dr. Shohei Itoh and Masahiko Miyaki of the Denso Corporation, a Japanese automotive parts manufacturer, developed the Common Rail fuel system for heavy duty vehicles and turned it into practical use on their ECD-U2 common-rail system mounted on the Hino Rising Ranger truck and sold for general use in 1995.[3] Denso claims the first commercial high pressure common rail system in 1995.[4]
Modern common rail systems, whilst working on the same principle sensor are governed by an engine control unit (ECU) which opens each injector electronically rather than mechanically. This was extensively prototyped in the 1990s with collaboration between Magneti Marelli,Centro Ricerche Fiat and Elasis. After research and development by the Fiat Group, the design was acquired by the German companyRobert Bosch GmbH for completion of development and refinement for mass-production Common Rail Nozzle . In hindsight, the sale appeared to be a tactical error for Fiat, as the new technology proved to be highly profitable. The Common Rail Injector Valve had little choice but to sell, however, as it was in a poor financial state at the time and lacked the resources to complete development on its own.[5] In 1997 they extended its use for passenger cars Common Rail Injector . The first passenger car that used the common rail system was the 1997 model Alfa Romeo 156 2.4 JTD,[6] and later on that same year Mercedes-Benz C 220 CDI.Common Rail Shim & Gasket kit have been used in marine and locomotive applications for some time. The Cooper-Bessemer GN-8 (circa 1942) is an example of a hydraulically operated common rail diesel engine, also known as a modified common rail.
