A psychiatrist who can sense neutrinos. Talk about a person who can see
right through you... (Rimshot)
The use of neutrinos to see a bone fracture is, of course, not a technology that is currently available to us. Scientists who wish to sense neutrinos nowadays use immense detectors like the Super-Kamiokande in Japan to find even a few, rare interactions between neutrinos and the more quotidian matter around them. |

Meh. Not very happy with the art today; I'm not sure what happened. Sorry, I'll try to do better next time.
As I mentioned last time, Mars is making its closest approach to Earth for thousands of years this month. Even from the most light-polluted city the planet will be easy to find. I noticed it by accident tonight: a bright, very red star shining steadily and purposefully low in the southeastern sky. Check this link from the Planetary Society for more on how to observe Mars yourself this month. |
