Walter H. G. Lewin - Center for Future Civic Media A native of The Netherlands, Professor Lewin received his Ph.D. in Physics from the University of Delft (1965). In 1966, he came to MIT as a postdoctoral associate in the Department of Physics and was invited to join the faculty as an Assistant Professor later that same year. He was promoted to Associate Professor of Physics in 1968 and to full Professor in 1974. Professor Lewin's honors and awards include the NASA Award for Exceptional Scientific Achievement (1978), twice recipient of the Alexander von Humboldt Award (1984 and 1991), a Guggenheim Fellowship (1984), MIT's Science Council Prize for Excellence in Undergraduate Teaching (1984) and the W. Buechner Teaching Prize of the MIT Department of Physics (1988).
Fibonacci Numbers, the Golden section and the Golden String Fibonacci Numbers and the Golden Section This is the Home page for Dr Ron Knott's multimedia web site on the Fibonacci numbers, the Golden section and the Golden string hosted by the Mathematics Department of the University of Surrey, UK. The Fibonacci numbers are The golden section numbers are 0·61803 39887... = phi = φ and 1·61803 39887... = Phi = Φ The golden string is Grid Paper PDFs Free Online Graph Paper / Grid Paper PDFs Downloadable and very printable, I find these PDFs extremely useful.

Used as part of a lesson, clips from movies can reinforce topics, spark discussion, and promote new perspectives. There's still a great need to introduce kids, and especially girls, to STEM fields like neurobiology, nanotechnology, and civil engineering. Whether it's a short clip from a Hollywood film to reinforce the concept of gravity or a feature-length documentary that highlights the work of engineers, incorporating movies into your lessons can help kids connect what they're learning in the classroom to the world at large. And even after the credits roll, you can extend the learning: Create a model, start a debate, or begin a community project that the film -- and your teaching -- inspires.

Book NRICH Bespoke PDBook Forthcoming EventsBook our Hands-on Roadshow 10 Maps That Will Change How You View The World Maps are one of those things you can lose yourself in for hours. Since their humble origins as scribbles in the sand thousands of millennia ago, maps have been useful companions during the development of human culture and society. Now, in an age of seemingly endless information, maps are more abundant, advanced and fascinating than ever before. Here are some of the most interesting maps we could find; hopefully, they will leave you looking at our little "pale blue dot" with a fresh perspective.
