INTRODUCTION
This post will be every bit as varied as its title suggests, featuring a mix of politics, mathematics, music, nature and photography (and possibly more).
SOME MATHS RELATED STUFF
I start with one of more recent followers, RobertLovesPi, and I have several pieces of his to share:
- I start with the first piece of his that I read, which is titled “The 15-75-90 Triangle” – a graphic is reproduced below:
- Next comes “The 43rd Stellation of the Snub Dodecahedron, and Related Polyhedra, Part One“, the first part of a series the whole of which I heartily recommend. It features some very impressive graphics, one of which I reproduce below:
- My third offering from this excellent blog is a short story “The T-Shirt from the Future” – here is the picture of the T-shirt:
My next piece, courtesy of whyevolutionistrue is titled “The Coffer Illusion“, which concerns the picture below:
If the illusion defeats you, you can find out where the circles are by going to the original post.
I finish this little section with a nod to the mathematical website Brilliant, which I am a regular visitor to (I am currently on a 64 day problem solving streak). As a sample here is a problem I solved today, rated at maximum difficulty by the site, pretty close to minimum by me:
You can look at solutions to this problem on the website, and I will reveal the answer on this blog tomorrow.
A FEW POLITICAL PIECES
There has been a lot of coverage from various people of events in Charlottesville. I choose to draw your attention to Richard Murphy’s excellent piece on Tax Research UK, titled “Charlottesville is a cradle of extremism: we should take note“. Below is a screenshot of the first few paragraphs:
My second link is to the petitionsite, regarding a young women in El Salvador who having been raped and then had a miscarriage has then been jailed for 30 years due to the Catholic church influence anti-abortion laws of that country. The screenshot below is formatted as a link to take you to this petition to sign and if possible share it:
I finish this section on a lighter note, courtesy of whyevolutionistrue. This little piece titled “Where is North Korea? Some Americans have no idea” reminds us how unacquainted USians are with that area known as the rest of the world! Here is a screenshot of the opening paragraph:
PHOTOGRAPHS
I usually end my blog posts with some of my own photographs, but this photograph section has an additional feature – as a nod to the principal subjects of many of the photos that follow I offer you a musica prelude – Ottorino Respighi’s “The Birds”:
