Five years after founding @malengo.org, it’s time to let it fly! Today I’m stepping down as CEO, and Chad Sterbenz is taking over. He brings decades of experience in related roles, and I’m grateful that he is throwing his talents behind our mission. 1/3

I will remain on the Board, where I will set up a new Impact & Evidence Committee that will advise the organization on how to learn about our impact; more on that soon. 2/3

In October 1786, the German physicist Georg Christoph Lichtenberg wrote to fellow scientist Johann Beckmann that if we want a sheet of paper to retain the same aspect ratio when it is halved or doubled, the aspect ratio must be sqrt(2). 1/n

How long do the sides have to be for the sheet to have an area of 1 sqm? b * sqrt(2)*b = 1 ==> b = 2^(-1/4) ≈ 841mm ==> a ≈ 0.841 * sqrt(2) ≈ 1,189mm 3/n

For your weekend entertainment, here are some impressions from a trip in a small airplane from Germany to the US last summer! I first did this in the other direction five years ago. My friend John came along again this time — he's a very experienced pilot, and of late also a world record holder!

The next day began with the dodging of thunderstorms on the way to Burlington, VT, where the little planelet was re-admitted to her home country. John said goodbye here and flew back home to Chicago.

Northern Canada means having to buy fuel by the barrel, but at least in Iqaluit you don't have to use your own wiggle pump. We continued on to Goose Bay, happy to be over land again most of the way.

The flight from Nuuk to Kangerlussuaq the next morning was very bumpy, but beautiful.

Once the weather allowed, we had a spectacular flight to Kulusuk; then Narsarsuaq on the Southern tip; and finally to the capital, Nuuk. The detour South bypassed the ice shelf, which is 9000 feet thick and dangerous because you cannot escape to lower altitudes if you encounter icing in clouds.

Stornoway to Egilsstaðir, Iceland is one of the longer overwater legs at 483 NM, but the Faroe Islands offer an emergency out. In Eglisstaðir we refueled and then continued to Reykjavik, across glaciers and past volcanoes. Reykjavik offered another IFR approach to minimums.

The next morning we flew from Glasgow to Stornoway in the Outer Hebrides, with beautiful views of the highlands. First use of the GoPro on the wingtip! (Sound on for Nimrod from Elgar's Enigma Variations!)

On departure the next morning, we didn't close the door properly, leading to a drafty flight and an unplanned landing in Oostende, Belgium. Then across the channel to the UK with a beautiful view of the cliffs of Dover, and a fuel stop in Norwich.
