Oops

Fell of my bike again yesterday. This time I have nobody else but myself to blame for rolling around in the gutter shrieking like a girl...

I've come a cropper about 4 or 5 times now, been hit by a couple of cars, slid on ice... but this time I just clipped the curb, locked my brakes and landed in a pile of horsesh!t. That's London for you.

Anyway, I really should read more of this. Full of top tips on how to survive on 2 wheels, apparently.

Ringpiece!

A cheap joke for a rather interesting story. Wired.com has a piece about the rings of Saturn (see what I did there...), in that the 30-foot thick bands of rock and ice that girdle the planet are not entirely uniform.

In a nutshell, every fifteen years or so Saturn reaches its equinox, which results in some very different light angles, reflections and suchlike, and the latest one has allowed folks in Colorado to study the rings in some detail. In so doing, they've found some areas to be thicker than others, caused by the gravitational pull exerted by Saturn's moons. Pretty cool stuff.

From one ring to another: Ever wondered what makes gold and copper so different to the other shiny metals? Why one is yellow, another orange? As it turns out it's all to do with electrons; yes, that old chestnut again. See for yourself: these folks explain it all far better than I ever could.

Of course, ever since people began rummaging in the dirt we've always had a fascination for a bit of bling. I suppose with gold being so unusual a metal it became more than an object of fascination, it became currency. Copper, too, would once upon a time have been a prized material: copper ingots were used for trading a heck of a lot, as was lead of course. And yet, my Grandmother remembers when Aluminium was considered rare and precious: we now know it's probably the most abundant metal in the earth's crust. I reckon that's a result of all the takeaways we eat.

I thank you ladies and gentlemen, I'm here all week.

Isn't technology wonderful?

I saw this story on Reddit of all places, as you do, and was immediately fascinated: someone claims to have imaged the s- and p-electron orbitals in a single carbon atom. Then I saw the comments below the story: shurely shome mishtake seemed to be the order of the day: why are they not sp- hybrids? Anyway, the paper has only just been accepted by Physical Review B so it may be a while before we see the details. However, sp- or no sp-, it still seems incredibly exciting. We shall see.

Also, I see that the folks at the European Space Agency have basically given NASA a resounding "meh" following the latest Hubble images (see previous posts), and gone and released some of the images their own Planck telescope has started to capture.

Lest we forget, Planck is the coldest object in the sky, chilled to -273 deg C (can't do the ascii), designed to answer some of the most complicated questions posed by astronomers. One idea is that a model of the initial expansion of the universe may be accurately determined. So, from the very small to the very large; how splendid. Have a good weekend!

My word!

Something in the Indescribable today: the legend of a man-eating bird!

Apparently the Maoris had this legend: a raptor big enough to catch and kill a child or small adult, called a "Haast's Eagle," or "Te Hokioi."

It's been extinct for 500 years, which might come as a relief, but even so I shouldn't wonder that such a creature would have been a truly amazing sight. Let's face it, a bird with a 3m wingspan would have been seriously scary. Here be dragons, and all that.

Busy, busy, busy

Dreadfully sorry, it's been rather a long time since my last post. I do have an excuse though, my book has been progressing very nicely and I'm about 1/3 or maybe even 2/5ths of the way through. I don't think it'll be finished by the end of the year but who knows?





Anyway, I'm not the only one who's been busy, those rather splendid people working on the Hubble telescope have been doing stuff since the big beast itself was upgraded. Look at this, for example. And taken from the same site...

All very pretty. Well, who knows, in a few years time we may even get an upgraded version of the Deep Field video. In case you haven't seen it, here it is.

Personally I think it is the most humbling, yet the most incredible and uplifting thing I've seen in a long while. Well, since this, anyway.
