To understand ecosystems, ultimately will be to understand networks. – B. C. Patten and M. Witkamp A while back I decided one way to apply my math skills to help save the planet was to start pushing toward green mathematics: a kind of mathematics that can interact with biology and ecology just as fruitfully as […]

6:17 PM | Hubble at 25: My picks
For the Hubble space telescope’s 25th anniversary (April 24, 2015), NASA released a picture of the Westerlund 2 star cluster that the telescope shot. The image shows an expanding shell of gas lit up by the radiation from a cluster of 3,000 stars at its center. On the occasion of a quarter-century of operations, here are my favorite […]

4:33 PM | Happy Birthday to Our Fellow 'Great Observatory'
If you are at all interested in astronomy, chances are you’ve heard that the Hubble Space Telescope is celebrating its 25th anniversary this week. What some people may not know is that Hubble is one of four siblings, so to speak. Back in the 1980s, NASA commissioned the"Great Observatories," each designed and built to study different wavelengths of light. The four Great Observatories, in order of their launches that took place between 1990 and 2003, are Hubble, the Compton Gamma Ray […]

3:28 PM | Il colombre
E' il pesce che i marinai sopra tutti temono, in ogni mare del mondo. E' uno squalo tremendo e misterioso, più astuto dell'uomo. Per motivi che forse nessuno saprà mai, sceglie la sua vittima, e quando l'ha scelta la insegue per anni e anni, per una intera vita, finché è riuscito a divorarla. E lo strano è questo: che nessuno riesce a scorgerlo se non la vittima e le persone del suo stesso sangue.Io non l'avevo mai visto. Ma dalle descrizioni che ho sentito […]

1:08 PM | The exoplanet 51 Pegasi b detected in reflected visible light
Image and further reading: ESO Text: A&A Twenty years ago, the discovery of 51 Peg b heralded the birth of a new field, exoplanetology. However, the Jupiter-like planet that orbits at only 0.05 AU from its parent star does not transit in front of its star. The emphasis therefore shifted toward the study of other […]

12:07 PM | Slightly Belated Star Talk TV Thoughts
Neil deGrasse Tyson’s TV talk show had its debut Monday night on the National Geographic channel, something that’s very relevant to my interests. It airs after I go to bed, though, so I set the DVR to record it, and watched it Tuesday afternoon. Then I was too busy yesterday to write about it… Anyway,…

11:00 AM | Radio Electron...
An electron in a magnetic field will turn circles and emit radiation. Adrian Cho - Science MagTopics: Cyclotron, Electromagnetism, Neutrinos, Particle Physics, RadiationPhysicists have long known that charged particles like electrons will spiral in a magnetic field and give off radiation. But nobody had ever detected the radio waves emanating from a single whirling electron—until now. The striking new technique researchers used to do it might someday help particle physicists answer a […]
