Vision Scientist | Lecturer | Guide | Amsterdam, The Netherlands join my online university at https://www.skool.com/geometric-vision-8685

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

The couple’s costly fur-trimmed and lined clothes (his purple silk velvet tabard trimmed with sable and her spring green houppelande lined with miniver) suggest the male subject is Giovanni di Nicolao Arnolfini, silk merchant from Lucca, who lived in Bruges & supplied fine textiles to Philip the Good of Burgundy, ruler of Europe's richest court, and patron of Van Eyck. 

The young woman has been identified as Giovanni’s wife Costanza, thought to have died in childbirth. 

The intimacy & tenderness of the couple, with their joined hands, is reflected in the convex mirror, which also bears witness to the shadowy presence of the artist, whose signature & date are just above: ‘Johannes de Eyck fuit hic 1434’ (Jan van Eyck was here 1434).

The painting passed into the Habsburg Collections (Margaret of Austria, Philip II of Spain) before The National Gallery.

Note: forthcoming Exhibition of Van Eyck at National Gallery London - from November 2026.

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.

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.

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.

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.
