Vikings between 900AD and 1100AD had Ulfbehrt swords. Swords so strong and flexible, so much better than any other western weapons, they were essentially magic. They’re real and about 170 of them are scattered in medieval weapon collections in museums.

They’re made out of crucible steel. This is a process for heating iron up to 3000 degrees to push out all the impurities and increase the carbon content. The process for producing crucible steel was unknown until the 1800s in the West when it was discovered during the Industrial Revolution.

So how did Vikings in 900AD lay hands on swords made of steel not discovered until 1800AD? Time travelers? Well, maybe. But the process was actually discovered first in Sri Lanka and southern India around the birth of Christ, and ingots likely came to Damascus and newly-established Baghdad via the Indian Sea trade route. And from there, Vikings reached the Middle East markets via the Volga Sea/Caspian Sea routes. They bought ingots in the marketplaces in exchange for northern goods (pelts, dried fish, etc) and brought them back home. Their blacksmiths forged the swords…

And because they were so storied, fakes appeared in West marketplaces everywhere. But because most people were illiterate, they failed to properly replicate the marks of a real Ulfberht swords…

Cool story and makes from an interesting possible driver for a campaign.

The big deal about quantum computing is that when you have that kind of power, you can model things – organic molecules, materials, the interactions of complex systems – down to the atomic level. That means you can figure out how to build all kinds of useful things, without having to actually build the ones that won’t work.

Which effectively means “a quantum computer worked it out” is like “a wizard did it,” only for SF.

Quantum computing is such an enormous advancement it’s unfair to even describe it in terms of computers as we know them.

Climate change, water pollution and fishing practices have been decimating coral reefs for decades, threatening the ecosystem that’s home to 25 percent of all marine species. Within the next 15 years, nearly three quarters of all reefs will likely be damaged or destroyed.

Scientists have long been searching for ways to help repair these delicate living structures. They’ve replanted reefs, using both natural and artificial materials. They’ve tried replacing reefs’ algae with stronger varieties. They’ve even used electric current to help stimulate coral growth. Lately, they’ve been working with one of the technology community’s current darlings, 3D printing. Printed reefs can closely mimic natural ones, providing a home for baby coral to take root and grow. The process is still in its infancy—in 2012, the first 3D printed reefs were sunk in the Persian Gulf off the coast of Bahrain, where the existing reefs had been badly damaged. Similar projects are in the works around the world.

I first encountered Spring-Heeled Jack in Tim Powers’ excellent The Anubis Gates. There’s great potential in the legend for casting him as an alien, a time-traveller, or something supernatural.

Tiny molecular machines. Their work marked the advent of nanobiotechnology.

James M. Tour, a professor of chemistry at Rice University in Houston, said the Nobel would bestow legitimacy on the field and help convince people that nanomachines are not just fantastical science fiction of the far future.

“No one is making money on these right now, but it will come,” he said. “These men have established and built up the field in a remarkable way.”

Dr. Tour predicted that the first profitable use of the technology might be machines that open up cell membranes in the body to deliver drugs. “It’s really going to be quite extraordinary,” he said.

Via Larry Panozzo. The article explicitly points out something I’ve been noticing for a while: at each stage of the development of technology, the previous stage’s cutting edge is packaged and standardised so that it can be treated as self-contained building blocks to make the next stage, which is why a twelve-year-old can now program a successful mobile game that would once have been beyond the most advanced computer scientists.

At the end, it talks about virtual decision support advisors, which sparked the thought: what about a future election where everyone used these advisors to decide who to vote for? All of a sudden, the candidates would need to switch from convincing voters to convincing AIs that their policies would benefit voters…

Deep Learning trying to go wide

A company called Bonsai joins a movement to democratize machine learning. Get ready to build your own neural net.

…But what if you could get the benefits of AI without having to hire those hard-to-find and expensive-to-woo talents? What if smart software could lower the bar? Could you get deep learning with a shallower talent pool? A startup called Bonsai and an emerging class of companies with the same idea say yes. Brace yourself for the democratization of AI. It’s a movement that might eventually include millions of people — and, some say, billions.
