Interesting, it works in German too.

While it was called “Preussen”, this orginated from the name Prussen.

And people from Russia are called Russen in 🇩🇪 .

People who know cars, is this this one?

I googled Corvette looking like Ferrari and it came up, but morphology is not full match:

I think those were the only decent FROG measurements I have ever gotten.

Long time ago, but I still remember that it was quite finicky.

It is quite a stark contrast, isn’t it? If you can afford such a car, you could also get nice coffee😅.

My girls like to go there on Sunday mornings, as it is the only coffee shop we can walk to.

People pull up in all kinds of cars, including Cybertrucks and other monstrosities.

Ohh, I went to flex my 8 fs laser pulses after compression (bottom row).

Well, it was @spie.org Photonics West, not our local coffee shop😅.

Neither can that dude; our streets have so many potholes and random bumps, this must be a pain to drive it…

Saw this car this morning at Starbucks.

My guess it cost more than a Ti:Sapph laser.

Still prefer an ultrafast laser over a sports car😀.

Yeah, quite amazing.

He beat Odermatt who is in his prime. By a second in first run; and then almost slipped in second run, but kept it together.

Aha, just as I worked on doing the new formatting…

I guess it’s still better to get it done anyways.

Swiss golden boy Von Allmen wins super-G to complete Milano Cortina hat-trick Switzerland's Franjo von Allmen joined a very exclusive club of Alpine skiers as he powered to his third gold medal of the Milano Cortina Olympics with a super-G masterclass down the Stelvio.

Third gold medal for Franjo von Allmen, wow!

He is only the third guy ever to win three olympic gold medals in skiing.

In terms of Swiss history, he has now surpassed Wilhelm Tell and Leonhard Euler.

Hopp Schwizz!

Somewhat frustrating when watching the Olympics and knowing folks stop at 4π solid angle on their microscopes (2.7 steradians more realistically).

Congrats to Kokomo Murase who did a 8π rotation jump to win the Snowboard big air event at the Olympics.

Also a big win for using radians over degrees!

This made me happy this morning:

USB powered laser diode with decent beam profile.

On demand collimated beams of different sizes.

Little ups while most things look pretty bleak.

Unrelated, I remember Lufthansa once doing go arounds a gogo at FRA with multiple crews on board a “heavy”.

Have to ask my buddy who flies for LH if that is still a thing.

Integrated in an imaging system with a 60X NA 1.49 lens.
