46 Fabulous Photos of Endeavour’s Last Ever Spacewalk May 27th, 2011: the last spacewalk for NASA’s Endeavour astronauts. Here, a fish-eye lens attached to an electronic still camera was used to capture this image of NASA astronaut Michael Fincke (top center) during the mission’s fourth session of extravehicular activity (EVA) as construction and maintenance continued on the International Space Station. Photo #1 by NASA A bright sun, a portion of the International Space Station and Earth’s horizon are featured in this image photographed by a spacewalker during the STS-134 mission. Photo #2 by NASA May 27, last day for Endeavour spacewalkers, NASA astronaut Greg Chamitoff continued to work on the International Space Station. May 27: A portion of the International Space Station and the docked space shuttle Endeavour is featured in this image photographed by a spacewalker, using a fish-eye lens attached to an electronic still camera, during the STS-134 mission’s fourth session of extravehicular activity (EVA). Flight Day 5: May 20, 2011.

Tools Solar System Dynamics on-line Tools The following is a list of on-line tools designed to provide data in support of solar system body observations as well as general scientific research. Ephemeris Generation The JPL HORIZONS On-Line Solar System Data and Ephemeris Computation Service provides access to key solar system data and flexible production of highly accurate ephemerides for solar system objects (planets, planetary satellites, comets, asteroids, the Sun, L1, L2, select spacecraft, and system barycenters). Small-Body Database Search Engine and Browser JPL's small-body database (SBDB) contains orbital elements and physical parameters for all known asteroids and most recent comets. The Small-Body Database Search Engine can be used to generate custom tables of orbital and/or physical data for all asteroids and comets (or a specified sub-set) in our database. The Small-Body Database Browser can be used to view data for a specified asteroid or comet. Small-Body Identification

Is the Universe a Holographic Reality? The Universe as a Hologram by Michael Talbot Does Objective Reality Exist, or is the Universe a Phantasm? In 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century. You did not hear about it on the evening news. In fact, unless you are in the habit of reading scientific journals you probably have never even heard Aspect's name, though there are some who believe his discovery may change the face of science. Aspect and his team discovered that under certain circumstances subatomic particles such as electrons are able to instantaneously communicate with each other regardless of the distance separating them. University of London physicist David Bohm, for example, believes Aspect's findings imply that objective reality does not exist, that despite its apparent solidity the universe is at heart a phantasm, a gigantic and splendidly detailed hologram.

Heavy Boots Editorial note: I received this as an email from a friend who got it from a friend who ... I do not know who the original author is, but I do believe this to be true. Who could possibly make it up? Heavy Boots About 6-7 years ago, I was in a philosophy class at the University of Wisconsin, Madison (good science/engineering school) and the teaching assistant was explaining Descartes. He was trying to show how things don't always happen the way we think they will and explained that, while a pen always falls when you drop it on Earth, it would just float away if you let go of it on the Moon. "No it wouldn't." the TA explained calmly, "because you're too far away from the Earth's gravity." I countered, "why didn't they float away?" "Because they were wearing heavy boots." he responded, as if this made perfect sense (remember, this is a Philosophy TA who's had plenty of logic classes). As we left the room, my friend Mark was raging. 1. About 47 percent got this question correct. 2. 13.
