Why we need the explorers: Brian Cox on TED.com

Posted By Shanna Carpenter

In tough economic times, our exploratory science programs — from space probes to the LHC — are first to suffer budget cuts. Brian Cox explains how curiosity-driven science pays for itself, powering innovation and a profound appreciation of our existence. (Recorded at TEDSalon London 2010, April 2010 in London, England. Duration: 16:29) Watch Brian Cox’s […]


LHC back in action

Posted By Jenny Zurawell

Tonight scientists at CERN are rebooting the LHC (Large Hadron Collider) in an attempt to recreate conditions fractions of a second after the Big Bang by crashing opposing proton beams, traveling at nearly the speed of light, into one another. Shortly after the LHC’s debut last September, a manufacturing glitch in wiring led to a […]


Large Hadron Collider set to try again in November

Posted By TED Guest Author

Last week, CERN announced that the world’s largest particle accelerator will power up again in November. However this time it will run on 3.5 trillion electron volts per beam, about half its expected energy level. Last year, the LHC shut down because of a fault between two superconducting bending magnets but recent tests have confirmed […]


Supercomputer visualizations show the guts of exploding stars

Posted By Matthew Trost

Scientists at Argonne National Laboratory are using the IBM Blue Gene supercomputer to model supernovas, and New Scientist has published a gallery of snapshots from the fiery visualizations. The images uncover the beautiful symmetry — and chaos — flowing through these explosive events. Visit the gallery now >> TEDTalks stars Carolyn Porco, Brian Cox and […]


The week in comments

Posted By Shanna Carpenter

This was an especially lively week on the TED commenting front, as our community tackled debates on swine flu, race and politics, and globalization. These amazing discussions can get a little heated — so we appreciate that there always seems to be a voice of reason that emerges from the group to soothe frazzled nerves […]


Another bonus of inventing the World Wide Web …

Posted By Emily McManus

Today, CERN’s been throwing a party to celebrate the 20th birthday of the web — which they date to the now-famous memo that Tim Berners-Lee wrote to his boss, sketching out a framework for a document-sharing system. As they tell it: Twenty years ago this month, something happened at CERN that would change the world […]


Hawking makes $100 bet that the LHC won't find Higgs

Posted By Emily McManus

Dr. Stephen Hawking has made a $100 bet that the Large Hadron Collider at CERN, which throws its first beam tomorrow, will not find the elusive particle knows as the Higgs boson. What makes the Higgs the most highly sought-after particle in physics? In his TEDTalk, Brian Cox describes the Higgs particle “in language a […]


Getting ready for Big Bang Day

Posted By Emily McManus

If all goes according to plan this week, the Large Hadron Collider at CERN in Geneva will circulate its first beam on Sept. 10 — a step that’s been compared to “switching on” the machine, but that is, as you’d expect, much more complicated than that. Once the first beam is established, the next steps, […]


Dropping mad science at the Large Hadron Collider

Brian Cox on the world's biggest experiment

Posted By Bgiussani

Sometime towards the end of August or possibly early September, the world’s biggest and most ambitious scientific experiment will go live: the LHC, or Large Hadron Collider will be started up at CERN in Geneva. Particle physicist and TED favorite Brian Cox (watch his TED talk) has written a must-read essay explaining the science of […]


The World Science Festival starts tomorrow

Posted By Tedstaff

Tomorrow, Thursday, May 29, 2008, begins the World Science Festival: a four-day celebration of scientific exploration and discovery in New York City created by TEDster Brian Greene. Members of the TED team will be liveblogging the event right here on the TED Blog, keeping you updated on the latest from many TEDTalks favorites who will […]


What really goes on at the Large Hadron Collider: Brian Cox on TED.com

Posted By Tedstaff

“Rock star physicist” Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings us along on a tour of the massive complex — and describes the vital role it’s going to play in understanding our universe. (Recorded March 2008 […]
