Its not so cut and dry. First off, the word they used to describe the eclipse translates to "twisted sun". I guess you could say thats an eclipse, but it could also be something else.


Do you think that is the only time the phrase is ever used? It might be ambiguous if that was the only time the term was ever attested, but we have thousands of Assyrian and Babylonian astronomical texts. Eclipses are discussed quite often in them, particularly in astronomical omen texts (where eclipses are bad news), so the meaning of the phrase is quite clear, based on many examples of its use.

idk what else would happen to the sun other than a total eclipse that you would really ever notice or describe as "twisted". based on personal experience from the recent eclipse the light level doesn't even noticeably change until you hit like 85% occlusion! nobody's writing down lovely partials as major events, it would be safe to say the majority of partials in history were not even noticed even without factors like "it literally happened after sunset"

Have you seen a solar eclipse either at or near totality?

The 791 eclipse would have only been about 74% occlusion at Assur and also would have happened right around sunset on the Mediterranean coast, meaning the sun would have set over Mesopotamia. Frankly it's extremely unlikely it would have even been noticed.

E: like actually peep this map. You tell me a Syracusan wrote about the 791 eclipse I'll believe you, but not an Assyrian


annular eclipse is also not the same as a total eclipse. moon's too far away so it's angularly smaller than the sun.

Apparently in geology they’re a fan of BP or Before Present. It’s not really standardized (and 74 After Present doesn’t make any sense) but they like setting the origin point at 1950 because that’s when atomic testing started changing the ambient radiation levels that get used for dating prehistoric rock samples and objects. There’s certainly worse time scales.

I've noticed this a lot in newer archaeological papers too, I suppose since that's related to geology but I feel like it's been catching on in recent years as some scholars want to move away from BC/AD but don't like BCE/CE either.

It's less because its related to geology and more because of the cultural baggage associated BC/AD.

I suspect part of the appeal is the sciencey element of relating your calendar and your archeological work to radiometrics. If you’re using carbon dating and providing the error margin then BP can be useful to clarify that’s what you’re doing. Though in truth, BP has only a limited relationship with carbon dating since the atomic testing had no impact on carbon decay that I’m aware of. On the other hand, if you’re relying on other evidence to establish an object’s age, or if you want to talk about a specific date, then other calendars are probably more appropriate.

I saw this from Tacitus linked in a discussion about deflation

quote:

Hence followed a scarcity of money, a great shock being given to all credit, the current coin too, in consequence of the conviction of so many persons and the sale of their property, being locked up in the imperial treasury or the public exchequer. To meet this, the Senate had directed that every creditor should have two-thirds of his capital secured on estates in Italy. Creditors however were suing for payment in full, and it was not respectable for persons when sued to break faith. So, at first, there were clamorous meetings and importunate entreaties; then noisy applications to the prætor's court. And the very device intended as a remedy, the sale and purchase of estates, proved the contrary, as the usurers had hoarded up all their money for buying land. The facilities for selling were followed by a fall of prices, and the deeper a man was in debt, the more reluctantly did he part with his property, and many were utterly ruined. The destruction of private wealth precipitated the fall of rank and reputation, till at last the emperor interposed his aid by distributing throughout the banks a hundred million sesterces, and allowing freedom to borrow without interest for three years, provided the borrower gave security to the State in land to double the amount. Credit was thus restored, and gradually private lenders were found. The purchase too of estates was not carried out according to the letter of the Senate's decree, rigour at the outset, as usual with such matters, becoming negligence in the end.

How did credit and banking work in first century Rome? Unfortunately there is a famous pop star named Roman Banks so my googling is confounded.

No I'm pretty sure it's so you can talk about the distant past without having to make reference to one particular Eurocentric religion. Changing the name to BCE/CE doesn't change the meaning of the date itself.

Also less mental arithmetic.

The bombs added carbon-14 to the air, and industrialism has diluted the atmosphere with carbon dioxide, but the actual decay rate remains unchanged. As a result those levels are returning to a baseline, and within a few decades the relationship between carbon dating and the bomb testing will essentially end.

Does it affect the really old samples or is it more like you can't reliably carbon date things from after when the nuke tests started

The latter.

C-14 levels in the atmosphere have actually fluctuated naturally through time and dendrochronology is used to calibrate the C-14 activity vs. age curve.

Thr concentration was abruptly doubled due to bombs, which means that you can actually date ringless trees based on when the c14 shows up in their tissues

Nessus posted:

It only gets added to living tissues, then starts decaying. Previously atmospheric levels were constant and thus living tissue held an equilibrium, with levels dropping once atmospheric carbon was no longer mxied in.

anything living after nuke tests has elevated levels (thus Before Present, since everything that died after that point is no longer reliable. Just blindly putting carbon levels into the previously valid formula would give a negative age)

There are also lots of other dating systems that are unaffected so it's not that big a deal. Low-background steel is for use in instruments that involve extremely precise and fiddly radiation detection. It's also not that important anymore since the elevated radiation from nuclear testing has mostly decayed.

Carbon 14 is produced by cosmic rays hitting nitrogen in the upper atmosphere. I can't imagine that nuclear testing made a meaningful impact on a stock and flow of that size.

Burning fossil fuels on the other hand has certainly altered carbon isotope ratios in the atmosphere. But we don't do 45 billion tons of nuclear explosions every year.
