Our home, from space.

Sixty-one years ago, Yuri Gagarin became the first human to make it into space and probably the first to experience what scientists now call the "overview effect." This change occurs when people see the world from far above and notice that it’s a place where “borders are invisible, where racial, religious and economic strife are nowhere to be seen.”

The overview effect makes man’s squabbles with one another seem incredibly petty and presents the planet as it truly is, one interconnected organism.

College students use AI to decode ancient scroll burned in Mount Vesuvius

“Some of these texts could completely rewrite the history of key periods of the ancient world."

When Mount Vesuvius erupted in 79 C.E., it buried entire cities in volcanic materials. While Pompeii is the most famous site affected by the natural disaster, the nearby villa of Herculaneum was also laid to waste—including over 800 precious scrolls found inside Herculaneum’s library, which were carbonized by the heat, making them impossible to open and recover their contents.

Which brings us to the Vesuvius challenge, started by computer scientist Brent Seales and entrepreneurs Nat Friedman and Daniel Gross in March 2023. The contest would award $1 million in prizes to whoever could use machine learning to successfully read from the scrolls without damaging them.

On February 5, the prize-winning team was announced.

Cavemen must have been perpetually late, given that humans didn't get around to inventing the sundial until 1500 BCE. The first attempts at measuring time via sun movement were shadow clocks created by the Egyptians and Babylonians. These led to the sundial, an instrument that tells time by measuring shadows cast by the sun on a dial plate. Sundials were our preferred method of timekeeping until the mechanical clock was invented in 14th-century Europe.

In 1972, Hamilton introduced the world's first digital watch. Its $2,000 price tag was hefty, but by the '80s, digital watches became affordable for the average person. Now, both technologies have merged in a cool invention, the digital sundial. Created by French Etsy seller Mojoptix, this outdoor clock uses the patterns on a suspended wand to mold natural shadows into a digital-looking time readout. The digital sundial has two major drawbacks: It only reports the time in 20-minute intervals, and it's not very effective after sundown. But it sure does look cool.

Here's the digital sundial in action!
