I got to join in on a great conversation this morning on Minnesota Public Radio's "The Daily Circuit", all about the Higgs Boson and what it means for the future of physics.
This is a fascinating issue. Finding the Higgs Boson (if that is, indeed, what scientists have done) means that all the particles predicted by the Standard Model of physics have now been found. But that's not necessarily good news for physicists. For one thing, it would have been a lot more interesting to break the Standard Model than to uphold it. For another, we're now left with a model for the Universe that mostly works but still has some awkward holes — holes that it might be hard to get the funding to fill.
Daily Circuit host Kerry Miller, Harvard physics chair Melissa Franklin, and I spent 45 minutes talking about what is simultaneously a beautiful dream and a waking nightmare for the physics world. And I got to make a "Half Baked" reference in a conversation about particle physics, so you know it's a good time, too.
The good folks on the most-excellent BBC Radio/Open University statistical literacy programme More or Less decided to answer a year-old Reddit argument about how many Lego bricks can be vertically stacked before the bottom one collapses.
They got the OU's Dr Ian Johnston to stress-test a 2X2 Lego in a hydraulic testing machine, increasing the pressure to some 4,000 Newtons, at which point the brick basically melted. Based on this, they calculated the maximum weight a 2X2 brick could bear, and thus the maximum height of a Lego tower:
The average maximum force the bricks can stand is 4,240N. That's equivalent to a mass of 432kg (950lbs). If you divide that by the mass of a single brick, which is 1.152g, then you get the grand total of bricks a single piece of Lego could support: 375,000.
So, 375,000 bricks towering 3.5km (2.17 miles) high is what it would take to break a Lego brick.
"That's taller than the highest mountain in Spain. It's significantly higher than Mount Olympus [tallest mountain in Greece], and it's the typical height at which people ski in the Alps," Ian Johnston says.
"So if the Greek gods wanted to build a new temple on Mount Olympus, and Mount Olympus wasn't available, they could just - but no more - do it with Lego bricks. As long as they don't jump up and down too much."

In the midst of the biggest natural disaster to hit the New York metropolitan area in modern times, most of the staff of community radio station WBAI was prevented from broadcasting - not because of a power outage, but due to management decisions that put prerecorded programming over the airwaves instead of the usual live broadcasts. The hacker/technology program "Off The Hook" has been kept off the air for an unprecedented three weeks, making it impossible to help listeners deal with the technological challenges of losing communications and connectivity throughout the crisis. While a small group of broadcasters was allowed to put live programs on the air during daylight hours, a 6 pm on-air curfew was imposed, effectively locking out the majority of the station staff, including "Off The Hook." This has led the members of the world's longest running hacker radio program to start searching for another broadcast outlet, as it doesn't seem that technology-based programming is taken seriously or considered a priority, based on these actions.
BURN: An Energy Journal, the radio documentary series hosted by former NPR journalist Alex Chadwick, has a 2-hour election special out. It's the most powerful piece of radio journalism I've listened to since—well, since the last episode they put out. You really must do yourself a favor and set aside some time this weekend to listen to “The Power of One.”
Energy policy, defining how we use energy to power our economy and our lives, is among the most pressing issues for the next four years. In this special two-hour edition of BURN, stories about the power of one: how, in this election season, a single person, place, policy or idea can — with a boost from science — affect the nation’s search for greater energy independence.
The documentary examines how "individuals, new scientific ideas, grassroots initiatives and potentially game-changing inventions are informing the energy debate in this Presidential Election year, and redefining America’s quest for greater energy independence." It was completed and hit the air before Hurricane Sandy, but the energy issues illuminated by that disaster (blackouts, gas shortage, grid failure, backup power failure at hospitals) further underscore the urgency.
During last night's storm emergency, I monitored the FDNY scanners to try and follow fast-moving and difficult-to-obtain details about what was happening where in NYC. For future reference, radioreference.com is an excellent way to do that (provided you have power and internet access). Along with that, you'll want to have two browser tabs open, for a cheat sheet on the codes the first responders use: Box Codes (find the location of the fire alarm boxes people use to get an FDNY response in an emergency), and FDNY 10 codes (shorthand developed in 1937 for common communication among first responders).
One good thing to keep in mind: not everything you hear on the scanner is confirmed fact. By definition, the first responders are often working with incomplete and unconfirmed calls for help, and chaotic situations. That, combined with the fact that it can be hard to understand what they're saying, make careful listening and sharing essential. Read the rest
BB reader Jane Lowers sends along this beautiful BBC Radio documentary about two men in California who have been together for decades, now facing one's terminal pancreatic cancer diagnosis. "I know both of them; Eric was a columnist at a radiology magazine I used to work for," says Jane. "Their house is every inch as insane as described. But the story -- trying to decide how to deal with a diagnosis, how to use the time you have, and how it can affect relationships -- was very well-described, I thought." Read the rest
Two of my favorite people talk about one of my favorite topics, all on the same radio program. Our very own Maggie Koerth-Baker was interviewed by my friend (and former NPR colleague) Alex Chadwick on KCRW's daily show "To the Point" today, to talk about "Geoengineering and the fight against climate change."
Everybody talks about the weather, but nobody does anything; and when people repeat that witticism, they make it sound as though someone should. Now, someone may. Geoengineering. Guest host Alex Chadwick explores whether we could use technology to alter the atmosphere and cool the warming planet. What could go wrong with that? There are scientists who think we should start trying to research exactly these questions.
Alex has been doing a lot of interesting journalism around energy issues lately, most notably with BURN: An Energy Journal. He was sitting in for host Warren Olney today.Read the rest
Tuesday night's As It Happens program on CBC radio featured a segment on the terrible human rights situation in Bahrain, opening with an archive interview with Zainab Al-Khawaja, daughter of the dissident Abdulhadi Al-Khawaja, who was snatched, beaten and indefinitely detained by Bahraini police a year ago. Abdulhadi Al-Khawaja is now on a hunger-strike and may die soon. As It Happens then interviews his daughter again about her father's situation and the human rights situation in Bahrain. Zainab Al-Khawaja explains that her father is risking his life to draw international attention to Bahrain's awful human rights situation, the hundreds of dissidents rotting in jail, some as young as 12 years old, facing torture and inhumane conditions.
As It Happens then interviewed Bernie Ecclestone, president of Formula One, whose big annual race is to be held in Bahrain this year. Ecclestone is the perfect picture of denial and callousness, as he blithely asserts that Bahrain is a perfectly nice place where protest is tolerated. He's smug about his race for expensive cars in a totalitarian police-state, and blames the media for any negative impression the world may have gotten about Bahrain.
Here's a recent CNN article on the Al-Khawajas, here's Murtaza Hussain on Salon on the same subject, and here's Democracy Now!'s archive of pieces on the family. Zainab Al-Khawaja tweets as @angryarabiya.
As I noted in a Boing Boing post yesterday, there's news of a possible change ahead for in-flight gadget rules in the US.
The Federal Aviation Administration currently prohibits passengers from using electronic devices on commercial flights when the plane is below 10,000 feet in altitude. But the FAA announced this week that after widespread demands to modify restrictions, there may be new efforts to review whether devices like the iPad or phones in "airplane mode" can be permitted safely during takeoff and landing.
Aviation journalist and pilot Miles O'Brien, who uses his iPad for navigation while flying his own plane, joined KPCC's Patt Morrison show today to discuss the news. Here's a direct MP3 link to the radio segment. It's a good listen. Read the rest
