Calm after the storm.....recent visit to Porthmadog.
All things computing, software engineering and physics related! Now also including retirement stuff.

Retirement activities proposed by Gemini
Here are some fun retirement projects:
* **Travel:** Explore new places, cultures, and cuisines.
* **Volunteer:** Give back to your community and help others.
* **Learn a new skill:** Take up a new hobby or learn a new language.
* **Start a business:** Turn your passion into a profitable venture.
* **Write a book:** Share your stories and experiences with the world.
* **Take up a sport:** Get active and stay healthy.
* **Spend time with family and friends:** Cherish your loved ones.
* **Relax and enjoy life:** Take some time for yourself to relax and recharge.
Well I can sign up to the last point for a while!

Paradoxically Olbers paradox
This is a typical photo of an Egyptian temple representation of the night sky.
Whats so strange about it?
No constellations, no 'brighter' stars, no Moon? It's effectively a night sky completely full of stars. Wherever you look there is a star. Exactly what Olbers paradox is all about - why is the night sky dark - if, in an infinite universe filled with stars, why would you not see a star wherever you looked? Essentially the night sky would then be bright!
Of course we now have an explanation for the night sky being dark - see Wikipedia Olbers paradox, for a start. Short answer is a finite universe and red shifted star light because it is also expanding. Well at least thats what we think at the moment.
So maybe those 👽 weren't so clever after all.....or maybe they know something we don't!
Again, I thought that was going to be it on the Egyptian front, but looking at these night sky depictions has raised another issue.....

Ancient Egyptian quantum experimentation
Following on from the previous post on wave-particle duality in ancient Egypt, what about this one.
Evidence of a Youngs slit experiment in the Dendera Temple of Hathor. The photo clearly illlustrates both the particle (triangles running down from the slit) and 'waves' (running up from slit and depicted as as ripples in a sea of stars).
Why is all this physics in the Temple of Hathor? Well clearly she was also a physicist - doing wave-particle duality experiments, being the personification of the Milky Way and the 'Lady of the Stars'.

Ancient Egyptian quantum physics
The Sun's rays are now depicted as lines with a hand at the end. The 'particle' triangles have now gone. Clearly the hand is there so that it can represent a 'wave'.
Ancient Egyptian Particle Physics continued.
Ok - feels like I'm heading down an ancient rabbit hole but I've been doing some extensive research (that's over my breakfast coffee) into neutrino hieroglyphs. I've come across this image - courtesy of the Metropolitan Meseum - hope that's OK.

Which shows an advance on the 3 neutrino view of the last post! I think this one is a bit later in time from 200BC ish. Clearly there was additional neutrino research undertaken and 5 types are now depicted as rays.
Check out current particle physics searches for a 4th 'sterile' neutrino type here,

so, looks like we have a bit more work to do to uncover the other 2! Which will require changes to the 'standard model' - it's those 👽 again ;)
