Who Was William Rollins and What Can We Learn?
Who was William Rollins and what can we learn? Stuart C. White UCLA Presented to AAOMR in Nov. 2005 Setting the Scene 15 BY BP: Big Bang 4.6 BY BP: Solar system evolved 100,000 BP: Homo sapiens evolved 1830: Gas tubes invented Michael Faraday 1791-1867 1830 Studied effects of electric current on gas • Tube was filled with a gas • Metal plates were connected to series of batteries • Gas slowly pumped out of tube • When the gas pressure became small enough, the gas began to glow Heinrich Geissler tubes mid-1800's • Built improved vacuum pumps • Produce low-pressure gas tubes in a variety of sizes, shapes, and configurations Julius Plucker 1801 - 1868 1858 • Noted that when residual pressure of gas inside cathode-ray tube is small, the glass at one end of tube emits light • Could change position of patch of glass that glowed by bringing a magnet close to the tube • Whatever produced this glow is electrically charged Rühmkorff spark inductor 1860’s onward - provided higher voltages Rühmkorff coil + Geissler tube Johannes Hittorf - 1860s Noted that in high vacuum tubes glow extends from negative electrode and produce a fluorescent glow if it strikes the glass walls of the tube Johannes Hittorf 1869 • When a solid object is placed between cathode and anode a shadow is cast on the end of the tube across from the cathode • This suggests that some beam or ray is given off by the cathode; these tubes soon became known as cathode-ray tubes William Crookes Confirmed previous work by Plucker and Hittorf, and showed that cathode rays are negatively -

Waves: Light, Sound and Other Oscillations by Richard Brock
IOP Education | Stories from physics booklet 4 Waves: light, sound and other oscillations By Richard Brock iop.org Stories from physics Stories from physics Introduction Message from the author Waves are a fascinating phenomenon to teach because they occur across a diversity The story of physics is intertwined with the stories of contexts and over a vast range of scales. However, the abstracted descriptions of of people. Richard has collected some amazing, waves found in curricula can present challenges for students. This booklet provides amusing and enlightening stories and I am very an assortment of stories that can help to contextualise waves and spark your students’ interest. pleased that the IOP is able to help him to There are stories drawn from the history of physics, including why the distinguished share them. I’m sure that you will be inspired physicist, Blondlot, came to believe in non-existent N-rays and how Tesla by the stories and their engaging retelling here. accidentally pre-empted Röntgen’s discovery of X-rays. You can read about how Newton fudged his data, why John Scott Russell chased a wave for several miles They will be of interest to any teacher and are down a canal and the polarisation navigation system the Vikings probably didn’t use. ready to use with students to bring the discipline You will also find out about contemporary research related to waves. Discover why alive and illustrate its reliance on human ingenuity mussels don’t like radio waves and read about the mysterious signals from space and frailty. that researchers found were being emitted from their own kitchen.
