We tend to believe that civilizational change is driven entirely by the invention of superior tools…but consider the washing machine. The technology was introduced in the 01910s but wasn’t widely adopted until the 01950s. Why?

In the early 20th century, laundering was entangled with class signaling, racist labor structures, and plumbing limitations. A fascinating exploration from JSTOR illustrates how the pace layers of commerce and infrastructure can only move as fast as culture allows:

Early electric laundry appliances promised to make housework easier. But convincing American households to buy them was another matter.

In 01851, Herman Melville opened Moby-Dick with the iconic line, “Call me Ishmael.” In 02014, two readers took him at his word: Stephanie Kent and Logan Smalley set up a real phone number for Ishmael, with a voicemail where callers could leave a message about a book they love.

Thousands of people have called to share stories of books that changed their lives. There’s even a refurbished pay phone where readers can pick up the receiver and listen.

Ishmael is still taking calls: 774-325-0503

The Call Me Ishmael project — named after the celebrated opening line of Moby-Dick — is an award-winning literary initiative that collects and shares anonymous voice messages about books people love.

Nearly every phone and computer on Earth relies on one plain-text file to know what time it is.

When a country changes its clocks with a few weeks’ notice, or Morocco pauses daylight saving for Ramadan, someone has to update that file. Since 02005, that someone has been Paul Eggert, a computer science professor at UCLA, who does it as a volunteer.

Take a look at this great data visualization to see the full story:

Four billion phones ask one text file what time it is. One lecturer keeps it in his spare time. We counted the rest.

The Long Now Foundation fosters long-term thinking. Our work encourages imagination at the timescale of civilization — the next and last 10,000 years — a timespan we call the long now.

In a remote corner of the driest state in the country, Anne Heggli's team has been keeping watch over the Earth’s oldest trees. Since 02012, Heggli’s Desert Research Institute NevCAN network has recorded conditions at the Long Now Nevada Bristlecone Preserve every eight minutes. The result is more than 120 million data points and a high-resolution portrait of how a bristlecone pine thrives.

Accompanied by artist/philosopher Jonathon Keats and paleoclimatologist Adam Csank, Heggli made the case for long science: patient, continuous observation that will help us answer the future’s most urgent climate questions.

“Imagine a pitch that starts with, ‘This is going to take 100 years.’ And then, ‘We’ll also need a forest.’ And on top of that, ‘We’ll also need famous writers.’” This is the story of Future Library, a century-long artwork — a forest growing future books that will remain secret until 02114 — and what it will take to keep it alive: https://na2.hubs.ly/H08fCcL0
