Remember a couple months ago, when you spent the better part of a week trying to understand the Big Bang in order to appreciate a huge, new discovery in physics? Now other physicists think that discovery might just be an artifact of data analysis — not a real finding at all.
...scientists cautioned that the result would have to be scrutinized thoroughly. And now a potential problem with the BICEP analysis has emerged, says Adam Falkowski, a theoretical particle physicist at the Laboratory of Theoretical Physics of Orsay in France and author of the Résonaances blog. The BICEP researchers mapped the polarization of the CMB across a patch of sky measuring 15° by 60°. To study the CMB signal, however, they first had to subtract the "foreground" of microwaves generated by dust within our galaxy, and the BICEP team may have done that incorrectly.
For their part, the folks at BICEP are unequivocally denying this. There's a very nice piece at New Scientist by Lisa Grossman that gives you some good reasons to be skeptical of the skepticism. Ultimately, nobody is going to know whether the BICEP results are legit (or not) until their work is replicated (or not) by another team of researchers ... something that could take another year to happen. Watch this space.
It’s a commonplace that in the natural world, males attempt to mate with multiple females, while females attempt to entice males into being monogamous; this is attributed to the high cost of producing an egg and bearing children (or laying eggs) for females, and the low cost of sperm production for males.
Mathematician Stephen Wolfram and his company do a lot of consulting for Hollywood. But he doesn’t often do it on an urgent basis because a movie is about to shoot and they neglected to “tech the tech.” When I first started looking at the script for [Arrival], I quickly realized that to make coherent suggestions […]
Can you “hear” motion or light flashes? If so, according to new research from City University London, you may be experiencing a not-so-rare form of synaesthesia. Synesthesia is the fascinating neurological phenomenon whereby stimulation of one sense involuntarily triggers another sensory pathway. For example, a synesthete might taste sounds or hear colors. (In this study, […]

You know as well as I that writing complex, long-long form text requires significant organization. You’re probably also well aware that Word just isn’t up to the task. That’s why I’m a huge fan of Scrivener, the software suite used by best-selling authors and technical writers alike.Scrivener is much more than another digital typewriter. With a […]
