Neural Navigator 🚀Castle at night with bats
The picture takes place in Belgium at dawn in the future. The weather is a violent cyclone, with swirling grey clouds illuminated by streaks of neon pink and turquoise from the rising sun attempting to break through. Rain lashes down, reflecting the city lights. The genre is Battle, depicting a surreal, impossible conflict. Soldiers clad in sleek, chrome armor, reminiscent of M.C. Escher’s tessellations, fight amidst a chaotic cityscape of decaying gothic architecture interwoven with […]
The Tigress Awakens1971 And Counting
Today is my birthday! And so I wrote a poem about being alive for open link day and fellow poets at Dverse. Enjoy!https://thetigressawakes.wordpress.com/2026/05/21/1971-and-counting/

Ferruginous Hawk
Did you know that 🦅 Ferruginous Hawks have an impressive hunting technique? They often glide on rising thermals, reaching speeds of up to 120 km/h (75 mph) as they dive to catch their prey. These majestic birds are known for their sharp eyes and powerful talons, making them efficient hunters in open grasslands and shrublands. 🌳 Text model: aya-expanseImage model: MoxieFlux1DS
DandomRudeDrawing Hands by M. C. Escher (1948)
Artist: Maurits Cornelis Escher
Year: 1948
Medium: Lithograph
Drawing Hands is a lithograph by the Dutch artist M. C. Escher first printed in January 1948. It depicts a sheet of paper, out of which two hands rise, in the paradoxical act of drawing one another into existence. This is one of the most obvious examples of Escher’s common use of paradox.
In the DarkM.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).
