The Face on Mars

APOD has a cool new picture of what that Face on Mars really looks like.

APOD Face on Mars

It still has a face-like appearance, although it does look like more of a natural, not artificially created structure.

The big high resolution version of the photo makes a really cool desktop background.

Farewell Voyager

APOD’s got a pretty cool representation of what Voyager 1 is about to encounter at the edge of the solar system.

90 AU out, and moving at over 3 AU/year. That’s over 448793612 km/year (278866864 miles/year) or 51197 km/h (31819 miles/h) or 14 km/s (8.8 miles/s). Now that’s fast.

IoP Book Sale

If you’re in the market for some physics related books, the Institute of Physics is having a huge book sale. Books are discounted up to 75%, so if they have a text you’ve been eyeing for a while, but have been putting off because it’s too expensive, see if it’s one the books on sale. The list of books sorted by title (which I’m browsing through now) is 18 pages long, so there are plenty of books to choose from. Lots of proceedings, lots of hardcore physics books, and a bunch of general interest books. The sale ends Dec 31, so go check it out!

Autumn’s here

Yesterday was the autumnal equinox. Soon, the weather will be cooling down, and leaves are supposed to be turning colour. Around here though, the weather changes from really really hot to just hot. And leaves don’t turn colour. The live oaks and palm trees stay green, and all the other trees just turn brown and drop their leaves. No brilliant display of colour, no brisk chill in the air. None of what I’m used to. Aside from the weather cooling down enough to make going outside enjoyable again, fall around here is a pretty dull season (hurricane excitement notwithstanding).

I miss having different seasons.

Identify this spider

Ok, there’s this big nasty looking spider hanging out by the sliding door to our room at my wife’s parents’ house. Somebody tell me what it is.
