Perhaps I’ve Been Too Effusive About Phil Plait Recently
Posted on December 23rd, 2009 No commentsBut it’s difficult to resist his enthusiasm. Click on the image below to get the Bad Astronomy explanation:
As I’ve said before, he left the presidency of the James Randi Educational Foundation to pursue a television opportunity. I hope it works out; he’s awesome.

Physics Insults and Pick Up Lines
Posted on December 23rd, 2009 No comments1. You are circumferencely enhanced.
2. Your normal force is greater than mine.
3. The integral of your curves approaches infinity.
4. I want to be your derivative so I can lie tangent to your curves.

Could Parallel Universes Be Congenial to Life?
Posted on December 23rd, 2009 No comments
… recent studies by Alejandro Jenkins and Gilad Perez, authors of our cover story, “Looking for Life in the Multiverse,” show that some other universes may not be so inhospitable after all. “We have found examples of alternative values of the fundamental constants, and thus of alternative sets of physical laws, that might still lead to very interesting words and perhaps to life,” they write. In other words, scientists get a “disaster” for life if their models vary just one “constant” of nature, but if they vary more than one they can find values that are compatible with the formation of complex structures and perhaps intelligent life. What would these universes be like?Many of us are captivated by the search for other beings in the vast cosmos beyond Earth. So it is ironic that we sometimes place such a paltry value on life that already exists on our own planet. Seven horrific tropical diseases, mostly caused by parasitic worms, ruin the lives and health of a billion impoverished people around the world by making them chronically sick, yet these ailments get less attention and money than HIV/AIDS, malaria and tuberculosis. In his feature article, Peter Jay Hotez presents “A Plan to Defeat Neglected Tropical Diseases.” Surely there is a way to provide the necessary drugs—which can cost just 50 cents per person—so that all people can thrive.

Making relativistic positrons using ultraintense short pulse lasers
Posted on December 23rd, 2009 No commentsHui Chen, S. C. Wilks, J. D. Bonlie, S. N. Chen, K. V. Cone et al.<br/> This paper describes a new positron source using ultraintense short pulse lasers. Although it has been theoretically studied since the 1970s, the use of lasers as a valuable new positron source was not demonstrated experimentally until recent years, when the petawatt-class short pulse lasers were de … [Phys.

Dust acoustic instability driven by drifting ions and electrons in the dust plasma with Lorentzian kappa distribution
Posted on December 23rd, 2009 No commentsZhipeng Liu and Jiulin Du<br/> The instability of the dust acoustic wave mechanicss driven by drifting electrons and ions in a dusty plasma is investigated by the kinetic theory. All the plasma components (electrons, ions, and dust particles) are assumed to be the Lorentzian kappa (kappa) distributions. The spectral indices kappa of the ka … [Phys.

Structure and dynamics of dilute suspensions of finite-Reynolds-number settling fibers
Posted on December 23rd, 2009 No commentsMansoo Shin, Donald L. Koch, and Ganesh Subramanian<br/> Many-fiber simulations and a linear stability analysis are used to explore the structure and dynamics that arise in a dilute suspension of sedimenting slender fibers with finite particle Reynolds numbers. Dynamic simulations based on a slender-body treatment of the fibers coupled with a pseudospectr … [Phys. Fluids 21, 123304 (2009)] published Wed Dec 23, 2009.
