This is such a great tool, try configuring it for roundabouts and have a great deal of learning by modeling.
This is an online edition of the classic technical reference Five Hundred and Seven Mechanical Movements by Henry T. Brown.
This site contains the original illustrations and text from the 21st edition of the book, published in 1908. It also includes animated versions of the illustrations, and occasional notes by the webmaster.
The video above was created using the results from the census on exterior finishes of single-family homes. It looks at the historical use of wood, brick, stucco, vinyl, fiber and ‘other’ options starting in 1977 and ending in 2017. The census accounts for up to 1.6 million houses each year and includes homes across the U.S.A., so provides a broad look at how finishes have risen and fallen in popularity over the full period. These changes in popularity not only account for aesthetic fashionability but also availability, cost and practicality. From a trend perspective, each finish dominated a specific decade, in terms of houses completed in that finish. Brick dominated the 70s, wood dominated the 80s, vinyl, which only became available in the 90s, dominated that decade, and stucco and fiber cement dominated the 2000s. ‘Other’ materials also saw their highest use during the late 80s and 90s.
This spring I reviewed the Packt publishing book Moodle 3 E-Learning Course Development – Fourth Edition
Within a week after it being published I had already recommended it for a teacher/consultant to use it to setup there online training course in support of their book/program. Take a look it is pretty great.
I have just finished reviewing another Moodle book for Packt which should be officially published soon.
