Explanation: How come the crescent Moon doesn’t look like this? For one reason, because your eyes can’t simultaneously discern bright and dark regions like this. Called earthshine or the da Vinci glow, the unlit part of a crescent Moon is visible but usually hard to see because it is much dimmer than the sunlit arc. In our digital age, however, the differences in brightness can be artificially reduced. The featured image is actually a digital composite of 15 short exposures of the bright crescent, and 14 longer exposures of the dim remainder. The origin of the da Vinci glow, as explained by Leonardo da Vinci about 510 years ago, is sunlight reflected first by the Earth to the Moon, and then back from the Moon to the Earth.


Just another funny guy in a funny hat with yet another funny story

Someone had told me somewhere in 2006 or 2007, to check out this ‘Human Design’, I did not know that one could make a chart, so the only impression I got was ‘Just another funny guy in a funny hat with yet another funny story’. As so many I’ve encountered before, where I just did not find the hook into. All these theories, all these philosophies, these systems.

Some time later, my chart was made, now I had the angle to look at it again. I was told to be a 4/6 Reflector, PLL-DLR, Right Angle Cross of Rulership. In between I had read some things about Human Design, but found it difficult to grasp, but ever since knowing my Type I really dived in and (re)searched anything and everything I could possibly find (online).

That was 12 years ago today 🙂 👍

Thank you sweet baby Jesus… I mean Ra
