Today, a short but earth-shaking bit of science, from over 2000 years ago.

The story of Eratosthenes and Earth’s circumference, as told by Carl Sagan

After hearing that the shadows disappeared at noon in the town of Syene (now known as Aswan), Eratosthenes achieved his understanding of our planet’s size by comparing the angle of the sun’s rays in the port city of Alexandria-at the same time.

The Sagan video won’t post for whatever reason, but this is the link:

Ladies and Gentlemen, we regret to announce that because this year’s annual Pi Day celebration falls on a Tuesday, it will have to be postponed. The good news is that pi is infinite. Any day can be Pi Day!

I will focus on pie at a later, more auspicious time. Until then, please enjoy both the mathematical concept and culinary reality of pi/e.

Despite weekend efforts to the contrary, my taxes remain unfinished (soon! really!). In the larger scheme of things, however, it’s not that big a deal.

In case you’ve ever wondered how to cure idiopathic persistent singultus, and really, who hasn’t? 

How to (Actually) Stop Hiccups – The Atlantic

First, exhale completely, then inhale a deep breath. Wait 10 seconds, then—without exhaling—inhale a little more. Wait another five seconds, then top up the breath again. Finally, exhale. Generally, you will find that your singultus is gone.

It’s been just over two years since the Perseverance rover began its quest on Mars. What’s it been up to? A lot, but this article has a summary and link to the whole of its adventure (so far) distilled into a time-lapse video.

The rover has now traveled almost 15 km (9 miles). In addition to studying numerous rocks, it has also collected and stowed away 18 sample containers of rocks, regolith, and even the Martian atmosphere, to be gathered later and brought to Earth in a future Mars Sample Return mission.

It’s like this: I have a whole folder titled 365, full of interesting and informative ideas for this blog. I even had an idea for the post I wanted to do today, but lo (for various reasons involving day job bureaucracy for both myself and Mr Man), ’tis not to be. Instead, I give you ChatGPT’s idea of “a quote about joy in the voice of my cat.”

“Joy is found in the simple things, like a warm sunbeam, a cozy napping spot, and a good belly rub. Purr-fect happiness is just a whisker’s length away.”

— Your Cat.

Because this is the sort of information that everyone needs.

For more on cats and whiskers:

* You may also know that “chat” is French for cat. So now we know what’s really behind A.I…. that’s right, animal intelligence.
