5:07 PM | Wave-Particle Duality' And Quantum Uncertainty - Two Sides Of The Same Mystery?
If you think of quantum physics in terms of information about a system, it is a lot less complicated, according to a new paper. In that context, features of the quantum world previously considered distinct  -  wave-particle duality and the quantum uncertainty principle - are different manifestations of the same thing.read more

2:50 PM | Advent Calendar of Science Stories 21: Hot and Cold
Another weekend day, another story I’m going to outsource a bit. In this case, to the original scientist, who at the time of his discovery was a 13-year-old schoolboy in Tanzania: In 1963, when I was in form 3 in Magamba Secondary School, Tanzania, I used to make ice-cream. The boys at the school do…

3:08 PM | Advent Calendar of Science Stories 19: Eucatastrophe
As I endlessly repeat, I’m an experimentalist by training an inclination, so I especially appreciate stories about experimental science. There’s something particularly wonderful about the moment when an experiment clicks together, usually after weeks or months of hard, frustrating work, when things just keep breaking. Of course, sometimes, breaking stuff can be a Good Thing.…

2:24 PM | Method and Its Discontents
Given that I am relentlessly flogging a book about the universality of the scientific process (Available wherever books are sold! They make excellent winter solstice holiday gifts!), I feel like I ought to try to say something about the latest kerfuffle about the scientific method. This takes the form of an editorial in Nature complaining…

9:10 AM | The Ongoing Issue of Dark Matter
New research data is shining an ever brighter light on the Big Bang – but dark matter remains elusive. In early December 2014, in Ferrara, Italy, leading astronomers discussed measurements taken by the Planck space observatory. From 22 December, the European Space Agency wants to make all data relating to this mission accessible online. The […]

The Most Radioactive Places on Earth Who on Earth is exposed to the most ionizing radiation? I’m filming a documentary for TV about how Uranium and radioactivity have shaped the modern world. It will be broadcast in mid-2015, details to come. The filming took me to the most radioactive places on Earth (and some places, which surprisingly aren’t as radioactive as you’d think). Chernobyl and Fukushima were incredible to see as they present post-apocalyptic landscapes. I also […]

2:55 PM | DNews: Search for Dark Matter's Calling Card Heats Up
We may have found evidence that elusive, mysterious dark matter -- something for which there is no direct proof -- is actually sterile neutrinos. And that's going to take some explaining, by way of a speed-tutorial on quantum mechanics from Julian.

8:00 AM | Being Disagreeable
Scientific method: Defend the integrity of physics (via zapperz) Faced with difficulties in applying fundamental theories to the observed Universe, some researchers called for a change in how theoretical physics is done. They began to argue — explicitly — that if a theory is sufficiently elegant and explanatory, it need not be tested experimentally, breaking [...]

2:54 AM | Quantum Immortality (Synopsis)
They say that a cat has nine lives, mostly because of their uncanny ability to find themselves in — and escape from — frequently perilous situations. Perhaps, of all the animals that he could have chosen, that’s why Schrödinger made his famous thought experiment about the most diminutive of felines. But there’s an incredible outcome that…

2:27 AM | In the matter of Walter Lewin, MIT goes medieval
By now most people must have heard the unpleasant news that Walter Lewin, the beloved and world-renowned physics teacher at MIT whose legendary video lectures drew comparison with the Feynman Lectures on Physics has been barred from campus and stripped of his emeritus professor title in response to charges of sexual harassment of a student in one of his MITx courses. Unfortunately, considering the very public fame that Lewin achieved, MIT has been frustratingly silent on divulging the details […]
