Physics Richard Feynman is a hero of mine. If you like physics, you should get to know his work. You can find a list of Feynman resources here. The Science Creative Quarterly & A DIALOGUE WITH SARAH, AGED 3: IN WHICH IT IS SHOWN THAT IF YOUR DAD IS A CHEMISTRY PROFESSOR, ASKING "WHY" CAN BE DANGEROUS SARAH: Daddy, were you in the shower? DAD: Yes, I was in the shower. SARAH: Why? DAD: I was dirty. The shower gets me clean. Regents Physics Introduction So, you’ve decided to take on the challenge of learning physics… a noble pursuit, no doubt, but what have you gotten yourself into? What do you hope to accomplish with this newfound knowledge? Where ever will you use what you learn? Why go to all this trouble?

Origin of the Chemical Elements During the process of stellar evolution nuclear fusion reactions take place within a star. These give rise to the formation of the chemical elements. Clues to the processes involved may be deduced from the graph below, which shows the cosmic abundances of elements (y-axis) plotted against atomic number (x-axis). Einstein for Everyone Title page, Preface and Table of Contents for Einstein for Everyone Introduction: the Questions Special Relativity Special Relativity: the Principles Special Relativity: Clocks and Rods Thingternet My Nest article got me thinking about smart metering. In my head, smart metering is all about energy efficient homes constantly connected to utility companies, controlling all my appliances to minimise my energy use. The reality is a bit different A few hundred thousand UK homes have had smart meters installed so far. The full roll-out will start in 2014 and should be complete by 2019. The meters being rolled out in the UK use the mobile telephone network to send usage data back to your supplier.

HyperPhysics Concepts About HyperPhysics Rationale for Development HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network. The bottom bar of each card contains links to major concept maps for divisions of physics, plus a "go back" feature to allow you to retrace the path of an exploration.

Radiation and Life: Education There would be no life on Earth without lots of sunlight, but we have increasingly recognised that too much of it on our persons is not a good thing. In fact it may be dangerous, so we control our exposure to it. Sunshine consists of radiation in a range of wavelengths from long-wave infra-red to short-wavelength ultraviolet, which creates the hazard. Beyond ultraviolet are higher energy kinds of radiation which are used in medicine and which we all get in low doses from space, from the air, and from the earth and rocks.
