M.C. Escher and CP Violation
I’ve had these pictures for quite a while and can’t remember where I got them from, but I used to show them in my lectures on Theoretical Particle Physics when I was in Nottingham to illustrate CP-violation and used them in this morning’s lecture at Maynooth.
The following picture by M.C. Escher is called Day and Night:
If you look at it you can see two kinds of symmetry emerging. One is a kind of reflection symmetry about a vertical axis drawn through the centre of the picture that applies to shapes but not to colour. The other is between black and white. But it is obvious that the picture doesn’t display these symmetries separately: to get a picture unchanged from the original you would have to do the mirror reflection and change black to white (and vice-versa).
The mirror reflection in the image can be taken to represent parity (P). Strictly speaking parity refers to a reflection through the origin in 3D rather than a mirror reflection, but it’s just for illustration. We know that a parity symmetry is violated in weak interactions just as it is in the picture.
The other possible symmetry, between black and white can be taken to represent charge-conjugation (C), the operation that converts particles into anti-particles and vice-versa.
While P is not an exact symmetry of weak interactions, it was long thought that the combination of C and P (CP) would be. Actually it isn’t. The story of the discovery of CP-violation is fascinating but I don’t have time to go into it here. It suffices to say that the Escher print also displays CP violation.
First lets do `C’, i.e. convert black to white and vice-versa. The result is:
Now reflect about the vertical mid-line to illustrate `P’:
If `CP’ were an exact symmetry then that image would be identical to the original, which I reproduce here:
You can see, however, that while some elements of the picture do look the same after this combined operation (e.g. the birds), others (e.g. the buildings at the bottom) do not. Although CP is not an exact symmetry of this picture, it is almost (just like it is in particle physics).

M.C. Escher remains the undisputed king of visual paradoxes. 🎨
Even when modern tech decodes his illusions, the real magic is how he dreamt up such complex compositions using nothing but a pencil and pure imagination. It is a humbling reminder that while computers are fast, the human mind is the original engine of infinite complexity. 🧠

Die Mathematik-Erklär-Videos von #3Blue1Brown sind eigentlich immer lohnenswert. Hier erklärt Grant Sanderson die Mathematik hinter M.C. Eschers Werk "Druckgalerie" und geht der Frage nach, was sich wohl im Zentrum des Bildes befinden könnte.

Wonderful analysis and animated recreation of M.C. Escher's "Picture Gallery" by 3B1B: https://www.youtube.com/watch?v=ldxFjLJ3rVY
The 2003 paper by De Smit and Lenstra who as number theorists were intimately familiar with elliptic functions ("doubly periodic complex functions") at the heart of the image https://pub.math.leidenuniv.nl/~smitbde/papers/2003-de_smit-lenstra-escher.pdf
I grew up in Baarn where Escher lived for a while but only learned later that he lived on the same street! D'oh. Of course we were separated by 35 years.

I am a loner drawn to multiplicity, he might have said.
I like it when things change but stay the same,
as a village in Italy creeps around and around a hill.

Samuel Jessurun de Mesquita (1868 Amsterdam – 1944 Auschwitz)
Am Morgen des 28. Februar 1944 macht sich Maurits Cornelius Escher von Baarn aus auf den Weg nach Amsterdam, um seinem alten Lehrer Samuel Jessurun de Mesquita in diesem kalten Hungerwinter ein paar Äpfel zu bringen. Doch die Tür in der Linnaeuskade steht offen, das Haus ist verwaist, die Fenster im ersten Stock sind zerbrochen, der Wind pfeift durch das verwüstete Atelier, das Inventar und hunderte Zeichnungen sind wild durcheinander auf dem Boden verstreut. Unter der Treppe am Eingang liegt eine Radierung – die Karikatur zweier lästernder Frauen –, auf der ein deutscher Soldatenstiefel einen Abdruck hinterlassen hat. Escher ist schockiert. Er klopft bei den Nachbarn. Die sagen: »Haben Sie das denn noch nicht gehört? Die De Mesquitas wurden abgeholt«. (Eschers Lehrer)

M.C. Escher über Kristalle
Lange bevor es Menschen auf diesem Globus gab, wuchsen alle Kristalle in der Erdkruste. Dann kam der Tag, an dem zum ersten Mal ein Mensch eines dieser glitzernden Fragmente der Regelmäßigkeit wahrnahm; – oder vielleicht stieß er mit seiner Steinaxt dagegen. Es brach ab und fiel ihm zu Füßen; dann hob er es auf und betrachtete es, wie es dort in seiner offenen Hand lag. Und er staunte.
Die grundlegenden Gesetze der Kristalle haben etwas Atemberaubendes an sich. Sie sind keineswegs eine Entdeckung des menschlichen Geistes, sie „sind“ einfach da – sie existieren völlig unabhängig von uns. Das Beste, was der Mensch tun kann ist, sich in einem Moment der Klarheit ihrer Existenz bewusst zu werden und sie zur Kenntnis zu nehmen. (1959)

„Wenn ihr wüsstet, was ich in der Dunkelheit der Nacht gesehen habe. Ich bin manchmal wahnsinnig vor Kummer gewesen, weil ich das nicht darstellen konnte. Jedes Bild ist im Vergleich dazu ein Fehlschlag, der noch nicht einmal einen Bruchteil von dem wiedergibt, was hätte sein müssen.“

M.C. Escher – Das Gleichgewicht von Teufel und Gott
Das ist das Gleichgewicht. Ich lebe von dieser Dualität. Aber das scheint auch nicht erlaubt zu sein. Die Menschen werden über diese Dinge gleich so tiefsinnig, dass ich bald davon überhaupt nichts mehr verstehe. Doch in Wirklichkeit ist es so einfach: Weiß und Schwarz. Tag und Nacht.“

Miracles
A person who is lucidly aware of the miracles that surround him, who has learned to bear up under the loneliness, has made quite a bit of progress on the road to wisdom.
