A flower -- can anyone identify the species? (I have a guess as to its indetity but I might be wrong).

As long as you send images to me (and I hope it will be for forever), I shall continue to share them with my readership. My purpose for posting these images is to remind all of us of the grandeur of the natural world and that there is a world out there that is populated by millions of unique species. We are a part of this world whether we like it or not: we have a choice to either preserve these species or to destroy them in search of short-term monetary gains. But if we decide to destroy these other life forms, the least we can do is to know what we are destroying by learning that they exist. If you have a high-resolution digitized nature image (I prefer JPG format) that you'd like to share with your fellow readers, feel free to email it to me, along with information about the image and how you'd like it to be credited.

Eat food. Not too much. Mostly plants.

post from Curious Cat Science and Engineering Blog on 28 January 2007 01:40:00 PM. © Curious Cat Science and Engineering Blog

Excellent articles on eating healthy but also provides a nice insight in the practice scientific inquiry: Unhappy Meals by Michael Pollan:Eat food. Not too much. Mostly plants. That, more or less, is the short answer to the supposedly incredibly complicated and confusing question of what we humans should eat in order to be maximally [...]

What Kind of Reader Are You

I ran across a quiz that identifies what sort of book reader you are. My own results are below the fold and I hope that you share yours with me too, along with your opinion of the questions they used;

Twisted Spaces: Fiber Bundles

post from Good Math, Bad Math on 28 January 2007 10:32:03 AM. © Good Math, Bad Math

It's been a while since I've written a topology post. Rest assured - there's plenty more topologyto come. For instance, today, I'm going to talk about something called a fiber bundle. I like to say that a fiber bundle is a cross between a product and a manifold. (There's a bit of ageeky pun in there, but it's too pathetic to explain.)

The idea of a fiber bundle is very similar to the idea of a manifold. Remember, a manifold is atopological space where every point is inside of a neighborhood that appears to beeuclidean, but the space as a whole may be very non-euclidean. There are all sorts ofinteresting things that you can do in a manifold because of that property of being locallyalmost-euclidean - things like calculus.

A fiber bundle is based on a similar sort of idea: a local property that does not necessarily hold globally - but instead the local property being a property of individual points, it's based on a property of regions of the space.

So what is a fiber bundle, and why should we care? It's something that looks almost like a product of two topological spaces. The space can be divided into regions, each of which is a small piece of a product space - but the space as a whole may be twisted in all sorts of ways that would be impossible for a true product space.

Sunday morning eruption of evil

post from Pharyngula on 28 January 2007 10:03:36 AM. © Pharyngula

The Nielsen Haydens filled my morning with horror, so I'm going to make you suffer, too. Behold, a Danish disco band pretending to be Apaches:

video details and more

It goes on for an interminable 4½ minutes; seriously, you've done your penance if you watch 20 seconds, long enough to spot the sequins and the Groucho mustache on the keyboardist. I recommend you turn it off before the Apache maidens emerge from behind the teepee—that was just too much.
