I now found a thinner non black marker! As you can see, every order extra is an extra little arrow. If I am in an artistic mood I can also draw (x^4,y-x^2,z-x^3) for a 3D effect.

These I draw every year I teach algebraic geometry (to be honest, for the ring I use C instead of R because the students must learn to draw R and see C)

Excellent drawing!

Usually the best part of my commute is the walk at the end (see photo).

Today however the bus was full of primary school kids, and halfway up the hill they started singing Sofia by Àlvaro Soler.
I am in my office now and I am still smiling. I may have tanked energy for the whole day.

No cat has been harmed for this picture.

Buona domenica!

I managed to keep a daily diary for a full year. A very small diary, but a diary nevertheless. Very useful as my memory never fully recovered from the depression years.

NB I had bought this notebook in early 2021, but soon lost it. A year ago I found it again.

Home from work, eldest is out to buy cat food, so sitting on her chair to give cat a warm place to lie down on.

Does the café also have Kuchen?

To get something vaguely Kuchen-adjacent I ended up buying this at a supermarket in Sežana.

I followed the “get started“ advice and emptied three 50x60 cm drawers by sorting old clothes into “I might still use” “give away” “trash”.

I had meant to do this for a long while and it only took me about one hour.

Thank you!

Today I arrived early and got pictures of the cute lecture room!

I am not sure how many of the students appreciate my devoting 1 hour every 5 to examples, drawings, and elementary calculations, but I sure do!

Bonus picture: corridor with lecture rooms NOT in alphabetical order.

I'm back home and tonight I get to sleep in the room with the cat because the room's owner is still on vacation.

I can't do anything helpful but you can spend a few seconds gazing on a fountain on a street close to the Vatican in Rome. No I don't know why there's a chubby dragon (the eagle is a symbol of Rome).

Bonus cat for Caturday.

I am in an airport without a mask on.

Yes I am sitting directly next to a door which opens all the time.

Greetings from the Black Forest! I am super happy because I found how to switch on the heating in my room*.

Q Who needs to see a picture of a cat who has regained his full winter fur and this looks particularly round?

A We all do.

This morning strong wind (70kmh average 100kmh top speed) and rain, after lunch the sun came out and the wind ceased.
This was taken about 5pm, I am looking out to sea and the handsome mountains in the distance are the Alps, which means good weather all the way there.

Having waited near the door for the return of his human for many* hours, the poor cat has become exhausted.

The air quality at FRA is surprisingly decent.

Wednesday afternoon in Oberwolfach's the program is "walk to the heavy and eat Black Forest Cake".
I walked almost 4 hours and 25+K steps and am very tired now.

There's a nice book in Oberwolfach's library which I have no time to read while I am here, but maybe I can ask my university to buy it.

Anyone has opinions?

Oberwolfach chronicles today: of course a maths research center uses robots!
