LineSolar Could High-Dive Jumpers Leap Over This Whole Pool? This is an older video from the World Championship in Dødsing. That’s about all I know except that it’s in Oslo, Norway. Watching this shows several very entertaining jumps. There are also a few jumps that look a little too close to the far edge of the pool. That makes the jump doubly scary. So, is it possible to run and jump from the high dive and hit the far end of the pool? Gathering Information After looking around on Google Maps, I found the location of the high dive. That’s about 16 meters from the end of the platform. Projectile Motion Yes, there is some guy jumping off a platform — in physics we would call this projectile motion even though he isn’t being “launched” like you might think. Since the only force is in the vertical direction, I can write the following two force equations. The acceleration in the horizontal (x-direction) would be zero and the acceleration in the vertical direction would be -g (or -9.8 m/s2). Since the x-velocity is constant, we can write the following:

It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator. All the controls for the accelerator, its services and technical infrastructure are housed under one roof at the CERN Control Centre. How many kilometres of cables are there on the LHC?

Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. This text owes a lot to many. i i i
