Royal Society exhibition revives 18th-century debate about shape of the Earth

Some members of the French Academy of Sciences interpreted measurements taken in Paris by scientists including Jacques Cassini as supporting the idea that the Earth was elongated at the poles, resembling a lemon or a melon.

By contrast, Isaac Newton had proposed that the centrifugal force caused by the Earth’s rotation would result in the planet being flattened at its poles, thus having a similar shape to an orange.

The Index itself is designed to always appear to be going 'up.' Stocks selected for the Index that have stopped improving are replaced with better performing ones. The rare times the Index drops are usually economic disasters. Slow down turns have less effect.
It's purpose is to get people to 'invest' seeing only the 'winners.'

Ancient Egyptian scribes and specific skeletal occupational risk markers (Abusir, Old Kingdom)

Our research reveals that remaining in a cross-legged sitting or kneeling position for extended periods, and the repetitive tasks related to writing and the adjusting of the rush pens during scribal activity, caused the extreme overloading of the jaw, neck and shoulder regions.

The problem with long term investments

If, in 1970, you invested $100 in a fund tracking the S&P index, then by 2023 the investment would have grown to $22,000, far more than it would have in other assets such as real estate or government and corporate bonds. Case closed, right? Put your money into an index fund and simply leave it there.

The Invisible Workers Behind AI: Exposing Underpaid Tech Labor

Meet the invisible workforce behind tech giants like Google, Facebook, Amazon, and Uber. These underpaid and disposable workers label images, moderate content, and train AI systems, often earning less than minimum wage. Their work is essential yet remains in the shadows, unacknowledged by the companies that depend on them.

Arabic Loanwords in Hebrew

The influence of Arabic, both spoken (in innumerable dialects, including those spoken by Jews) and written, took place in the mediaeval and modern periods of Hebrew; its vocabulary forms more than half of the Hebrew lexicon, according to the renowned dictionary of Abraham Even-Shoshan (Rosenstein, 1906–1984). The approximately 8,000 lexical items in the Bible are not sufficient to entirely meet the needs of either a written language or a spoken one.

Ancient DNA sheds light on the genetic origins of early Iron Age Philistines

Our analysis suggests that this genetic distinction is due to a European-related gene flow introduced in Ashkelon during either the end of the Bronze Age or the beginning of the Iron Age. This timing is in accord with estimates of the Philistines arrival to the coast of the Levant, based on archeological and textual records (2–4).

Indigenous Arabs are descendants of the earliest split from ancient Eurasian populations

The Arabian Peninsula was the initial site of the out-of-Africa migrations that occurred between 125,000 and 60,000 yr ago, leading to the hypothesis that the first Eurasian populations were established on the Peninsula and that contemporary indigenous Arabs are direct descendants of these ancient peoples.

AI is exhausting the power grid. Tech firms are seeking a miracle solution.

As power needs of AI push emissions up and put big tech in a bind, companies put their faith in elusive β€” some say improbable β€” technologies.

5 Famous Cartographers You Need to Know About

Gerardus Mercator is perhaps well-known for all the wrong reasons. His last name evokes the infamous Mercator projection, which depicts the world in a distorted way. The projection has been criticized for putting Europe at the center of the world and favoring the northern hemisphere by making countries there appear bigger than they are in reality.
