That's like saying that anybody who's ever drawn a circle knows about Pi.

but they don’t have a clue that they are using the Pythagorean formula, so the pi statement by the gentleman above doesn’t follow logically.

aware of that formula. I learned it in junior high school. Most carpenters have also gone to school. A lot of carpenters even know some basic trigonometry, which is also taught in high school. "How long do those rafters need to be?" A $15 calculator will provide the answer in a second, but an old book on carpentry I have, from the 19th century, has tables in it that let you calculate rafter length using trig.

WTF is this doing in Science?

Their astronomers predicted future astronomical events in calculations which required the theorem, also thousands of years earlier. When the library at Alexandria was burned it made the clay tablets permanent, so we can read them today.

The news here is not that this occurred "before Pythagoras" but before contact with more settled, literate, "civilized" (in the sense of having permanent cities) societies. Which just shows we need to fine-tune our concept of what "primitive" means. (Literally, it means "first, original", not "ignorant".)

Pythagoras codified, and presumably proved, the theorem which bears his name, but that doesn't imply he was the first to know of it. Don't think we need an astrology "expert" (oxymoron alert!) to tell us that.

From The Telegraph:

...

The new book, published today to coincide with today’s summer solstice, shows how within one of Stonehenge’s earliest incarnations, dating from 2750BC, there lies a rectangle of four Sarsen stones which when split in half diagonally forms a perfect Pythagorean 5:12:13 triangle.

When people make claims like this, I file them with the pyramidiots and pay them no further attention
