There's no sense in being precise when you don't even know what you're talking about. – John von Neumann
The dark, inner shadow of planet Earth is called the umbra. Shaped like a cone extending into space, it has a circular cross section most easily seen during a lunar eclipse. For example, last Saturday the Full Moon slid across the southern half of Earth’s umbral shadow, entertaining moonwatchers around much of the planet. In the total phase of the eclipse, the Moon was completely within the umbra for 51 minutes. Recorded from Beijing, China, this composite eclipse image uses successive pictures from totality (center) and partial phases to trace out a large part of the umbra’s curved edge. Background stars are visible in the darker eclipse phases. The result shows the relative size of the shadow’s cross section at the distance of the Moon, as well as the Moon’s path through Earth’s umbra.

This line is too true… my father used to say, “Give me a business that has no customers and no employees, and I’ll be a happy man.”
Photographer Mark Mawson has published a wonderful series of fourteen new underwater ink photographs entitled Aqueous Fluoreau. The images are stunning not only for their vibrant colors but their almost sculptural appearance. His previous projects from the same family, Aqueous and Aqueous II are also incredible and worth your time. If you liked this, also check out the work of Alberto Seveso. (via behance)
As part of their series on road accidents, BBC News mapped every recorded death on the road in Great Britain, from 1999 to 2010. That’s 2,396,750 road crashes. As you’d expect, the map looks a lot like population density, but check out the videos, which show twelve years of data compressed as if it were one week, played out over a few minutes. Each light represents an accident.
A reworking of a sentiment I say a lot these days.
It never occurred to me, when I was younger, that if I got successful, I would have to work twice as hard. I thought being “successful’ was not having to work…
But success is a very delicate flower. It doesn’t take a very heavy elephant in order to trample it to the ground.
So one has to work twice as hard, keeping those pesky elephants out of the yard.
The trouble arises when you get SO BUSY battling the elephants, you forget all about the flower. We’ve seen it happen, many times before.
