And it turned out to be a that little path next to the Royal Observatory in Greenwich, not the Prime Meridian line. The 0° meridian is what the GPS uses for global navigation, the discrepancy results from the fact that the Prime Meridian was originally measured without taking it into consideration that the Earth isn’t a perfect smooth ball (if the measurements are made inside the UK, as it it was originally done, this does’t lead to as much discrepancy as when vaster areas are included).
We are very grateful to brother Robert and his awesome colleagues from the Urania observatory for tonight’s adventure. We saw Jupiter and its four main moons, Saturn and Venus. And refreshed the most visible summer stars in our memory.

The telescopes were brought to the panorama floor of the museum “het MAS” by the Urania observatory staff and volunteers, including Robert Matheus – a very special someone who has already done so much for us in the past.
Simon into Simon’s eyes, is it like a mirror reflected by a mirror? (Simon’s best friend is also called Simon).
Simon returned to the Solar System in Processing Coding Challenge by Daniel Shiffman – something he tried before and got stuck. He has now successfully completed both the 2D and the 3D parts:
In this project Simon combined two exercises and one example from Daniel Shiffman’s Nature of Code book, Chapter 5 – Physic Libraries. The specific physics library used here is Box2D. Simon combined exercises 5.6 (Bridge) and 5.10 (Attraction Apply Force), and example 5.7 (Create a windmill) to create a motor that catapults particles towards an attractor. If the particles fly past the attractor, “bricks” can be added to the canvas by clicking the mouse – the weight of the bricks helps regulate the motor in the right direction. For this project, both gravitational attraction and global gravity force were applied:
This challenge is part of the spring 2017 “Intelligence and Learning” course at NYU’s Tisch School of the Arts Interactive Telecommunications Program. Simon was especially happy to find out that Daniel Shiffman left a couple of personal comments praising Simon’s progress and offering help in pushing his code to Danniel’s GitHub repo.

Simon didn’t finish this coding challenge. He went as far as building a spaceship and controlling it. He also made it reappear after it hit the edges. He got stuck with the asteroids part.
On Saturday Simon had his second astronomy workshop at the local observatory. The pages below is “homework”. He wasn’t particularly enthusiastic doing it but found tasks 4, 5 and 8 intriguing and was proud of himself when everything was completed. I always struggle with myself when giving him such “compulsory” tasks as he works better autonomously or at least when being able to chose the problems (which is often possible when using an online math platform, for example).
He also doesn’t like writing things down for someone else, in other words when he doesn’t see any practical value in it for the future. I’ve noticed that he prefers writing things down for himself to remember. Sometimes he even gets up at night to write something down, it’s quite funny to watch.
He said he liked his second workshop but couldn’t answer the question whether he learned anything new. He literally said “I can’t say yes or no to this question”. The workshop was about stars and galaxies. The first workshop was about constellations. Simon also confided to me that he is a little bit afraid of the third workshop next month: it’s called “3, 2, 1 Go!”. He is old enough to understand they would definitely not be taking an actual space flight during the workshop, still it seems to be triggering the old fears he’s always had of (accidentally) stepping in an aircraft and taking off.
On Saturday Simon started his monthly classes at Urania, the local observatory.
