If you are in NYC, please help! Below is a frame from a video recorded inside The Oculus, the main hall of the World Trade Center Transportation Hub. For a 3D vision project we would like to know the length and width of the marble tiles. We prefer the metric system. Thanks!

I do not like the summer heat but I do like to walk while talking about science and mathematics in 17th century Amsterdam. So I scheduled an Amsterdam Geo-Walk in the early morning of Wednesday 22 July. That is in 10 days when it is predicted to be a little cooler. www.skool.com/amsterdam-ge...
Amsterdam Geo-Walk
A guided tour through 17th century Amsterdam. Where cartography meets geometry. Where the Dutch Golden Age meets the Scientific Revolution.

I visited Amsterdam for the first time (without parents) in the early 1980s. Ed van der Elsken captured 1982 Amsterdam in his documentary “Een fotograaf filmt Amsterdam”. The city was clearly less international than it is now, but paradoxically also more diverse. Link below.
The Arnolfini Portrait, masterpiece of Northern Renaissance, oil on oak panel, 1434 by Jan van Eyck, died in Bruges #OTD 1441; tender memorial probably of wife who died in childbirth; richly detailed interior of brass candelabra, snuffed candle, faithful dog, mirror reflecting artist. ALT NG London

I have heard people say that getting a PhD means overly specializing in an extremely tiny piece of knowledge. I think that it is essentially an exercise in realizing how f#€k!ng difficult it is to actually really understand something.
Adam J French captured the Zeitgeist perfectly.
this graduation speech moment is notable, and her amazed shock at having failed to read the room feels instructive. when you're inside the bubble, you think everybody else is. but everybody isn't.

In the final assignment of this year's Vision for Autonomous Robots course the students have to create a Visual 3D map and do the navigation on that map. Luckily there is an Aibo robot dog overlooking their progress from its watchtower.
Happy GIS Day! 🌍❣️ Felt fitting that the theme of the #30DayMapChallenge was projections today! I want to dive into the math behind these sometime, it’s fascinating!!
For reasons I do not recall the Geo-Walks have always been on weekdays. So, the next Amsterdam Geo-Walk is on Saturday 15 November, starting at 10:00. The main characters are father & son Blaeu, and Mayor Hudde, with cameos of Descartes and Huygens. You can sign up at www.skool.com/amsterdam-ge...
It is election night here in the Netherlands. We voted today for the members of parliament in the Second Chamber. It is quite unpredictable this time. I always enjoy looking at the people behind the reporter at the gatherings of the political parties. As an amateur anthropologist.
Deze info heb ik nu even nodig. Dank Steeph!
Naast klimaat is er tijdens de verkiezingen veel te weinig aandacht voor alle ontwikkelingen rond het thema digitaal. AI, tech sovereignty, cyberwar, chip tekorten, election hacking, etc... Maar te weinig kandidaten met kennis op de lijsten. Dus stemadvies (mijn). Check verder nerdvote.nl #TK2025
As a citizen of Amsterdam, I was invited to celebrate its 750th anniversary in City Hall on Dam Square. I was mainly interested in the 6.24-meter-diameter floor maps by Joan Blaeu in the Burgerzaal. I made a cameo appearance during an interview for local news channel AT5. I am the man in blaeu.
The Royal Palace Amsterdam is probably the only building in the city that is exactly aligned with the cardinal directions. Strangely satisfying.
Natural Perspective is an approach that basically ignores the optical projection. Euclid called it 'visual cone’ (300 BC). Gibson later called it 'visual solid angle’ (1986). I apply Rational Trigonometry (Wildberger 2005) and get pleasantly simple expressions. youtu.be/9qCtaVkFZsI

In the 7th and final session today I gave a summary of the theory of vision I am developing. I realised I have shared many partial results but have never given a overview of all the steps in the vision process. If you want to join me on this adventure, sign up at www.skool.com/geometric-vi...
