In the Bible, the value Pi is 3.0

1 Kings 7.23 (KJV)

And he made a molten sea, ten cubits from the one brim to the other: it was round all about…and a line of thirty cubits did compass it round about.

March 14

Happy birthday Albert Einstein - Born today in 1879.

Happy Pi Day (3.14) to everyone else.

Measure the circumference of a flat circle of any size. Divide by its diameter, and you get Pi.

The approximation 3.14 is 99.95% accurate. Good for most Pi emergencies.

In Florida, at 345-feet, Britton Hill is the highest elevation — the lowest highest elevation in United States. This makes Florida supremely susceptible to sea-level rise during Climate Change.

An objective truth even if you don’t believe in Climate Change. Just Sayin'.

PROPHESY: When AI perfects deep-fakes of people, places, & things, no news will be trusted. Even those who previously believed fake news will think their fake news is faked. At that moment a tear in the spacetime continuum will open and swallow all social media from the internet.

Yeah, this is real, if slightly embarrassing, given my history with the little ice-ball.

Moments ago I captured the Moon.
You can too, if you act real soon.

That sickle in the sky
We call waxing crescent.

Behold evening twilight.
Our Moon — luminescent.

If you missed last week’s free screening of Shot In the Arm, now thru Dec 31, you can gift a private viewing — to yourself, or others.

The documentary, by @ScottHamiltonKennedy, looks compassionately at how anti-science thinking feeds vaccine hesitancy.

We've all heard it told: 'days get shorter in the Winter'. But since today is the December Solstice, the first day of Winter and shortest day of the year (in the North), that means the days instead get **longer** in the Winter.

Just sayin'.

It’s that time of year again - December Solstice - with the least daylight (in the N. Hemisphere) and most daylight (in the S. Hemisphere).

As you might surmise, on Earth’s equator it’s equal night & day all year round. So residents there experience none of this.

Don’t know why I should care about the science literacy of others. But I do.

Maybe it’s because the future of civilization depends on it.
