Engineers from Caltech have discovered that Leonardo da Vinci’s understanding of gravity—though not wholly accurate—was centuries ahead of his time.

In an article published in the journal Leonardo, the researchers draw upon a fresh look at one of da Vinci’s notebooks to show that the famed polymath had devised experiments to demonstrate that gravity is a form of acceleration—and that he further modeled the gravitational constant to around 97 percent accuracy.

Da Vinci, who lived from 1,452 to 1,519, was well ahead of the curve in exploring these concepts. It wasn’t until 1,604 that Galileo Galilei would theorize that the distance covered by a falling object was proportional to the square of time elapsed and not until the late 17th century that Sir Isaac Newton would expand on that to develop a law of universal gravitation, describing how objects are attracted to one another. Da Vinci’s primary hurdle was being limited by the tools at his disposal. For example, he lacked a means of precisely measuring time as objects fell.

Meta is preparing a fresh round of job cuts, according to a report from the Financial Times. Two people familiar with the matter told the Financial Times that there has been a lack of clarity around budgets and the future headcount at the company. The job cuts are expected to take place around March, but it’s unknown how people could be affected.

The lack of clarity has resulted in staff noting that not much work is getting done, as managers have been unable to plan ahead, the report says. Certain budgets that would normally be finalized by the end of the year still haven’t been finalized, and decisions that would usually take days to be signed off on are now taking a month in some cases.

Meta did not immediately respond to TechCrunch’s request for comment.

Explore what would happen if humans were suddenly eradicated from the world, and the Earth was left to heal itself. From the safety of nuclear power plants to the fate of pets, livestock, and wild animals, this video takes a detailed look at the environmental and societal impacts of such a scenario. Discover how air quality and greenhouse gas emissions would change and the Earth’s temperature would slowly return to its pre-industrial levels.

The ship design has ‘solar wings.’

Designer Jozeph Forakis has introduced the world’s first 3D-printed super yacht concept, and it’s called Pegasus. The concept is 88 meters long and comes complete with reflective ‘Solar Wings,’ allowing it to have zero emissions and an infinite range.

The idea for the futuristic yacht was conceived on a beach in Koufonissi island, Greece. Forakis claimed to be “inspired to create a yacht as close to the sea and nature as possible, made of clouds floating above the waterline, becoming virtually invisible,” according to the designer’s page.

Feb. 11 (UPI) — The death toll from Monday’s devastating earthquakes in Turkey and Syria is continuing to climb, surpassing 25,000 as of late Saturday, according to a new official count.

Officials confirmed more than 80,000 injuries as of 7:30 p.m. local time stemming from the 7.7 and 7.6 magnitude earthquakes which struck early Monday morning, according to the Turkish Ministry of Foreign Affairs.

Nearly 2,000 aftershocks also hit the region with more than 13 million people across 10 provinces affected in some way.
