But I’d also like to think that every individual’s impact is far greater than that - call it the butterfly effect - but I do always visit Pere Lachaise and visit Apollonaires grave: he invented a term I use every day: surreal!

When I first visited France it was Poitiers (figure that out! 😹) and in the cathedral there were all these panels reading “merci” from WW1. Even in Pere Lachaise so many monuments are so weathered by nature (not human memory) that this must just be the way things are.

A minor actress in the 1930s and a theater director in the 1950s in Paris, she died in relative obscurity. But last night, after figuring out who she was, I realized I probably was the only person on earth today remembering Germaine. She must have lived such an extraordinary life!

Three years ago I found these pictures in a pile of trash on a corner in the 19th eme of Paris. Turns out this is actress Germaine Rodger (1910-1975). I had forgotten I placed them in a book and they fell out last night. Made me think about memory and remembrance.

The friends I met (gave a cat face to a friend’s kid due to privacy issues but how incredibly lucky I am to have friends like this around the world?)

Montmartre at dusk is the most beautiful thing you can experience on earth.

I found a spot in Venice where I was just so lucky to be there.

Yes the canicules were terrible this year. The hottest temperature ever recorded in Paris and it just will get worse. I did my best by going to pools (Pallieron the 19th, the great pool at Butte aux Callies-and even the Seine, Canal Saint Martin, and other places!)

It was amazing. One of the top ten art experiences of my life. Close behind on the third floor of the bourse was Bill Viola (who I once had dinner with at the university of Chicago but who passed last year) piece Fire woman. Breathtaking.

View from the Ligne 6 line from Dupleix to Bir Hakeim in Paris. Feels very cinematic with this Max Richter music.

Climbed a mountain or at least a very big hill in the Puy du Dôme region in France near Clermont Ferrand with my colleague Cederic Bouquet.

Sunrise in Montmartre in Paris. I will always for the rest of my life be amazed and astounded that a friend offered me this opportunity to experience all of this.

Went yesterday to the Bourse de Commerce in Paris to see Fujiko Nakaya’s piece “Cloud 07156” in which the rotunda filled with clouds. It was amazing. Here is a timelapse…it was probably the best work of modern art I’ve experienced.

The pool at Butte Aux Cailles in Paris. They should be winning Olympic records going at these speeds!

I didn’t add sound to this video: there was a busker playing the violin on the car that I was on! Still has to be the best view from any train on earth.

This is mundane but Got my hair cut by a guy @chrisinparis.bsky.social suggested who is Arabic, doesn’t speak a word of English but has a cool shop with Budgerigar birds inside. Really nice guy who gives a great haircut in case you’re in need of one in Paris 9th / 18th…

I love it but I love even more remote parts of Paris: the coulee vert, the Rue de la Butte-aux-Cailles, these places are amazing!

Truly is the best station on earth. You have the 2 and the 4…where else do you need to go? 😹

Was here after having pho in Belleville. What a beautiful view of Paris! But is there any not beautiful view of Paris? 😹

Spent the afternoon with a former student Debrille who was in Paris for a day and is now a professor at the University of Washington! Gave a tour of Montmartre. Was great to reminisce and talk. She is working on amazing things. We also happened to have been born in the same hospital years apart!

Interesting - I was just walking by that very place in Montmartre. It’s also where Renoir made his famous painting!

Hung out at the Tuileries for a while watching the sun set over the Olympic torch and contemplating life. What an amazing city - you can see here Concord (where Louis XVI met his end) and the Arc de Triomphe in the distance.

Went swimming in the Seine today and it went swimmingly well due to the high quality filters they use in the water to keep it clean.

Okay since folks will ask the woman in the picture we had a moment when the subway train blew her skirt up and she looked back and said she was so embarrassed and I said “truly it’s all good I would have made the same mistake!” So be careful in Paris walking over those grates!

I’ve had the kind of few days that I never expected I’d have in a lifetime due to my friend @chrisinparis.bsky.social. I’m taking the day to sweep a terrace, feed cats, water plants, but I hope everyone once in their life gets a chance to have the same kind of cool days. (Funny about photo 2! 😹)

Spoke with a charming American woman about why counterfeit is so problematic and it truly is going back to antiquity. Here is one early example of wine vassals having to have different tops due to counterfeit 3000 years ago!

When I do go out I usually try inexpensive places like this Algerian place near Ménilmontant (Ligne 2) which cost less than 10 euros…or this other Moroccan place in Barbés that cost like 5 euros. I’m not going to “Guy Savoy” on my professor income! 😹 You can find cheap eats in Paris!

I don’t often eat out in Paris for a few reasons - I’m usually alone 😿, and I enjoy going to markets 😻(a lesson from @chrisinparis.bsky.social)But I met friends who wanted to try Bullion Racine (Bullion restaurants are notoriously inexpensive) - look at the gorgeous decor and food (my bill was $20)

If you’re in Paris 18 (Montmartre) stop by this record store on Rue Pierre Picard - live music and live cats!

One of the amazing things about being with my friends in Roquebrune was the food - we never went to a restaurant as it is so much better to go to the market see what is good and go from there. I will incorporate this lesson in future classes on culture and food…

You get the “good” figs once I depart! 😹 Honestly I will remember the figs and Gorgonzola for the rest of my life! I’ll be in the old folks’ home telling anyone who will listen “I once was in Roquebrune - in France! - and had these figs…”
