Long's Peak solo: Lamb's Slide, Loft, Clark's Arrow.

This weekend my climbing partner was out of town, so I decided to do something long and solitary. I decided to try Long's Peak via a reasonably technical route. Enough to make it fun, but not too dangerous to solo. And to make it as solo as possible I decided to start on Monday.

In May we tried to climb Long's via a variation of the Clark's Arrow (Loft) route, where you get to the Loft by climbing Lamb's Slide to its top and then traversing the top of Flying Dutchman Couloir to the saddle itself. Last time we made it only to the top of Lamb's, so this time I decided to start really early. After leaving Fort Collins at midnight, I drove to Estes and ended up starting hiking at 1-35am, from a deserted parking lot. The moon went down by the time I got above the treeline, and I saw Milky Way for the first time in my life. That thing alone was worth all the trouble. And there was more to come ;-). The night was really dark, so I could discern the silhouette of the mountains just by the line between a starry blackness and a tar-like blackness. It was surprisingly warm, and even with the wind picking up I felt comfy in a thin T-shirt.

At 3-35am I got to the Chasm Lake, which was invisible. I could only see what my LED headlamp was illuminating, an oval spot several meters ahead of me. I thought that I'm gonna get in trouble finding my way to the Mills Glacier, but it was surprisingly easy. At 4-25am, when the sky started to change color, I was looking up the Lamb's Slide. After taking a little 15min break I put on my crampons, took one of my ice axes and started to kick steps up the couloir. The snow was perfect, firm but not icy, which made for a very fun climb. As I was getting higher, so was the sun, first turning Diamond red, and then orange. After getting above the Broadway I took some photos:
That's looking down the Lamb's Slide. After 1 hour of climbing I got to the top, from where it was easy to traverse on to the Loft. Here is the top of Flying Dutchman:Another fun and easy patch of snow that brought me to the Loft at 5-40am, with a great view of Meeker with its Flying Buttress (the prow in the center):As it turned out, this was the easiest part of the ascent. The real fun part started higher up...

To be continued.

Remix.

Только что нашел в глубинах жесткого диска:

Захожу к операм в кабинет, а как правило в любом оперском кабинете висят на стенке листочки А-4 с каким нибудь умным изречением, типа: "если вас съели у вас есть два выхода" и т.д. и т.п., сегодня прочитал:

"Трудно собирать выбитые зубы сломанными руками, когда в глазах темно.." и подпись Конфуций.

И я понял что это ментовской ремикс на известное выражение китайского философа: "Трудно искать черную кошку в темной комнате особенно если ее там нет".

Plato's "Allegory of the Cave".

что было -- то и будет, и что делалось -- то и будет делаться, и нет ничего нового под Солнцем!
Екклесиаст

It amazing what people come up with over 2000 years ago. Following an excellent tip from my climbing partner, Morgan (thanks! the advice is greatly appreciated!), I read Plato's "Allegory of the Cave". It's one piece of deserving reading!

P.S. It was a required reading for a political science class.

Wonderfully intangible: Memes.

During a very cool discussion with my boss about Richard Dawkins, I was acquainted with a concept of memes, which is a unit of cultural information exhibiting a gene-like behavior. I found the concept to be a great example of a pure "informational entity". Wonderfully intangible.

A riddle.

A man is being hanged. There is a man in the crowd of observers who is asked of his relation to the guy on the gallows. He doesn't want to admit it, so he answers in a riddle:

-Brothers and sisters I have none, but that man's father {pointing to the man about to be hanged} is my father's son.

What is the relation between the condemned and the man in the crowd?

Mono-monostatic body ("GÖMBÖC").

Arnold's conjecture that convex, homogeneous bodies with less than 4 equilibria points (mono-monostatic bodies) exist was shown to be correct. In other words, it's possible to make a "come-back kid" {"ванька-встанька"} from a block of homogeneous material. So no matter how you drop it, it will straighten itself out and get on all four paws :-). Here is a page with a neat video demonstrating how "GÖMBÖC" rolls itself into equilibrium. And this Wikipedia article does a much better job of concisely explaining what this thing is (and what it does).
This picture is taken from a full paper: P. L. Varkonyi, G. Domokos Mathematical Intelligencer 2006, 28(4), 1.

P.S. Why less than four equilibria points, not just one? Because both stable and unstable equilibria count, hence gomboc has two equilibria points, not one.
