Visualising China: explore historical photos of China Gigantic Swiss atom smasher breaks world record The world's largest particle accelerator, the Large Hadron Collider, has set a new world record for colliding two beams of more particles together than ever before. The Large Hadron Collider (LHC) at the CERN physics lab in Geneva, Switzerland, has been operating since 2009, slowly ramping up its power levels and the intensity of its particle beams. Beam intensity is measured in luminosity, which corresponds to how many particles — in this case protons — are packed into each beam. The more protons that are accelerated along LHC's 17-mile long (27-km) loop, the greater the chances that two protons will smack into each other head on. "Beam intensity is key to the success of the LHC, so this is a very important step," CERN director general Rolf Heuer said in a statement. The LHC set the new beam intensity world record around midnight Geneva time on April 22. With the new intensities of the LHC, physicists should know soon whether the Higgs boson exists or not.

2012 Update from the CEO Velocity, execution and focus Sergey and I founded Google because we believed that building a great search experience would improve people’s lives and, hopefully, the world. And in the decade-plus that’s followed, we’ve been constantly delighted by the ways in which people have used our technology—such as making an artificial limb using old designs discovered online. But we’re always impatient to do better for our users. Last April, I began by reorganizing the management team around our core products to improve responsibility and accountability across Google. A beautifully simple experience across Google Creating a simpler, more intuitive experience across Google has been another important focus. Think about basic actions like sharing or recommendations. When you sign up for Google+, you can use Circles to group people into different categories, such as “Friends,” “Family,” or “Rocket Scientists,” and then engage with them just like in real life.

Reiserecht: Kundin bucht Bordeaux statt Porto Stuttgart - Eine Buchung ist auch dann gültig, wenn die Mitarbeiterin eines Reiseunternehmens den Zielort wegen undeutlicher Aussprache des Kunden falsch verstanden hat. Der Kunde ist dafür verantwortlich, dass der Mitarbeiter ihn richtig versteht, urteilte das Amtsgericht Stuttgart-Bad Cannstatt. Das berichtet die Deutsche Gesellschaft für Reiserecht in ihrer Zeitschrift "ReiseRecht aktuell". In dem Fall hatte eine Kundin einen Flug nach Porto buchen wollen. Vor der verbindlichen Buchung habe sie zweimal in korrekter hochdeutscher Sprache die Flugroute genannt, erklärte die Mitarbeiterin. Diese Art von Fehlbuchung ist kein Einzelfall: Jährlich besuchen mehrere Urlauber einen Ort namens Rodez in Frankreich, die eigentlich nach Rhodos in Griechenland wollen.

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
The Internet map 6 Ridiculous Myths About the Middle Ages Everyone Believes When you think of the Middle Ages, chances are you picture gallant knights sitting astride brilliant destriers galloping through a sea of plagues, ignorance, and filth. And you can hardly be blamed for that, when everything from the movies you watch to your high school history teacher (who was mainly the football coach) has told you that ... #6. Scientific Progress Was Dead Getty The Myth: They call it the Dark Ages for a reason. Getty"No, we can't cross the ocean there, don't you see that sea monster in the way?" The Reality: Aside from the fact that, as we've already explained, most people in the Middle Ages did not think the Earth was flat, the church wasn't responsible for killing science -- to the contrary, it was largely responsible for saving it. After the barbarians invaded Europe and Rome went the way of the dinosaurs, the Catholic church was the last remaining aspect of Roman culture in Western Europe. SjuPfft, like people are going to want to learn a whole other set of characters.
