- Simple Harmonic (and non-harmonic) Motion § Harvard Natural Sciences Lecture Demonstrations

Think ..."Some time ago I received a call from a colleague. He was about to give a student a zero for his answer to a physics question, while the student claimed a perfect score. The instructor and the student agreed to an impartial arbiter, and I was selected. I read the examination question: The student had answered, "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring the rope up, measuring the length of the rope. The student really had a strong case for full credit since he had really answered the question completely and correctly! I suggested that the student have another try. In the next minute, he dashed off his answer which read: "Take the barometer to the top of the building and lean over the edge of the roof. At this point, I asked my colleague if he would give up. "Well," said the student, "there are many ways of getting the height of a tall building with the aid of a barometer. "Fine," I said, "and others?" "Of course.

Stone Island Heat Reactive Jacket *notcot in wearable , 07:18 Thermochromatic goods seem to come and go and never quite disappear… remember when American Apparel brought it back and AZFN did their version too? Well latest to run into is Stone Island’s Heat Reactive Jacket “A hooded bomber jacket in cotton nylon canvas with thermosensitive liquid crystals, the garment changes colour according to the temperature. The fabric of the heat reactive jacket is treated with a thermo-sensitive coating that changes colour at high temperatures. Beginning at 27 degrees the molecules within the micro- capsules of the external strata undergo a rotation modifying the light course. The colour of the garment gradually begins to morph from the dark colour of the surface coating to a much lighter and brighter surface colour. See the video of it dramatically changing colors Tags: fashion - gifts - outdoors - shopping - technology

After reading an article in a science magazine about a new developed polymer called “D3O™”, they travelled to the UK to discuss the need for low profile, flexible, high impact reductive products within the industries they are still both actively involved in. After years of prototyping, testing and developing, the Xion PG brand (formerly known as Xion Stuntpadding) became known within the underground scenes of various early adaptors. Although Xion PG initially started to design universal body protection for stunt applications, it soon became evident that the products were suitable for a much greater audience. Everyone, confronted with the risk of getting injured, either professional or leisure wise, will highly benefit from our protective product line.
