Reading "why we travel" by Ash Bhardwaj while traveling. Came across the following quote which equally well applies to doing math:

#books #math #mathSky #travel
... humans have 'a natural inclination to solve the information gaps'. And the closer we get to solving a riddle, the more we want to do so.

Müssen wir wirklich nicht-hilfreiche Stereotypen auch noch auf Flaschen drucken?

What does it mean (to you) to understand a piece of mathematics?

I like to start my days in the Cafeteria with a coffee and some research. Most days the same other researchers also come and sit here.
The black walls in the back are all chalk boards. They are freshly cleaned each morning ready to be filled with math during the day.

Hello and Welcome to all new people here in my little corner of the sky.
Today I'd Like to share a sneak peek into my office shelves.

Weihnachten kommt nicht immer passend. Manchmal kommt es zu früh, mal zu spät, mal ungelegen. Aber es kommt.
Weihnachten erinnert uns, dass auch in kalter und dunkler Zeit Platz (und Not) für Wärme und Licht ist.

In diesem Sinne:
Frohe Weihnachten!

Die Goldbach Vermutung besagt, dass jede gerade Zahl größer als 2 die Summe zweier Primzahlen ist.

Christian Goldbach beschreibt diese Beobachtung erstmals 1742 in einem Brief an Leonhard Euler.
