Stephen Hawking’s Legacy Includes Making His Work Widely Approachable

We are saddened by the passing of physicist Stephen Hawking. One of the great minds of our time, Hawking’s work to apply quantum theory to black holes launched his career and led to his best known theoretical discovery that black holes emit radiation, aptly known as Hawking radiation.

Thinking back on Stephen Hawking’s contributions to humanity, it strikes us that one of his most important is his embrace of pop culture. While his scientific discoveries and writings are what will stand the test of time, in our own age it is remarkable that Stephen Hawking is a household name around the world.

Hawking’s first book, A Brief History of Time, has sold more than 10 million copies and for many readers was their introduction into the way physicists view space and time. It was written for general consumption and not reserved for those who were already bathed in the jargon of theoretical physics. It sent the message that contemplating science is something that is fun to do in your spare time. This work continued with his more recent mini-series Into the Universe with Stephen Hawking created for the Discovery Channel.

A fan of the series, Hawking appeared in an episode of Star Trek: The Next Generation in 1993 and made subsequent, often repeat, appearances on The SimpsonsFuturama, and The Big Bang Theory. This was great fun for all science geeks who knew of his work, but it has a far more profound effect of normalizing interaction with a world-class scientist. Appearing on these shows told the story that the pursuit of knowledge is cool.

Having scientists in the public light is crucial to research and advancement. It lets the general public know what kind of frontiers are being pursued, and why that matters. This trickles both up and down, inspiring the next generation of scientists by introducing deep topics at an early age, and ensuring funding and opportunities for this upcoming wave of researchers has widespread support.

Stephen Hawking showed us some incredibly complicated secrets of the cosmos both through his discovery, and through his ambassadorship of scientific knowledge. He will be greatly missed but leaves behind an admirable legacy which we can all strive to live up to.

The Inaccurate Predictions Of Back To The Future

Sometime this evening, after we haven’t rehydrated a pizza for dinner, all of the events portrayed in Back To The Future will have happened in the past. This is it. This is the day all your dreams die.

So, what’s so special about the technology in Back To The Future that we don’t have now? Hoverboards, obviously, but a lot of people have been doing their part to make sure we have something like a hoverboard on this important day. Last week, the record for the longest hoverboard flight was broken by a Canadian company making large multirotor platforms. While it’s called a hoverboard, it’s really not in the spirit of the device that would recreate the skateboard chase scene in front of Hill Valley’s courthouse. For that, you’ll need something that doesn’t use propellers, at least.

There’s a better way to construct a hoverboard than by strapping a few blenders to your feet. Last summer, Lexus built one with superconducting materials and magnets. Yes, it’s effectively the same demonstration you’ve always seen with superconducting materials, only this time it’s dressed up with pro skaters. There are tens of thousands of dollars worth of magnets in the Lexus hoverboard, making this entirely impractical for anyone who wants to build their own.

next-yearThere is another option if you want a hoverboard. This day, last year, Hendo Hoverboards launched a Kickstarter with the best media blitz we’ve ever seen. They built a hoverboard that is basically a quadcopter, but instead of propellers, they use magnets. These magnets produce eddy currents in the metallic, non-ferrous ‘hover surface’. The grand prize for this Kickstarter? Today, October 21, 2015, you’ll be invited to a VIP event where you will not only get to ride a hoverboard, you’ll get one to take home. Price: $10,000.

News Drones
News drones. People still read newspapers.

This company isn’t in the market of building hoverboards; they have a much, much more grandiose idea: the founder wants to use hoverboards as a stepping stone to an active earthquake mitigation strategy for buildings. Yes, buildings can hover inches above their foundation, just in case an earthquake strikes. You say the power might go out during an earthquake, causing the building to fall inches to the ground? I never said it was a good idea.

Lucky for us, the Hendo hoverboard did prove to be a proof of concept that a ‘spinning magnet’ hoverboard is capable of supporting the weight of a rider. We know a few people have been working on this technology before the Hendo hoverboard was announced, and replicating the Hendo hoverboard build shouldn’t cost more than about $1000 USD. We’re eventually going to have to do this, and we’re going to replicate the Pitbull hoverboard, bojo, because we want powah.

So, what else of Back to the Future Part II hasn’t become a reality? News drones. People don’t read newspapers anymore. Self-driving cars are more realistic than hovercar conversions. Pepsi Perfect exists, but only at a Comic Con. Nike Air Mags exist, but not with power laces. The world of Hill Valley still has fax machines, and I really want to rehydrate a pizza.

cubbiesIt’s alright, most of the technology of Back to the Future was just a joke; ‘Queen Diana’ would have never happened, and what exactly was the point of Gray’s Sports Almanac if you can look everything up on the Internet?

There was one possibly accurate prediction in Back to the Future: The Chicago Cubs may win the 2015 World Series. Let me repeat that, for effect. The most accurate prediction of the future given to us in Back to the Future was that the Chicago Cubs win the World Series. That’s how inaccurate Back To The Future was.

F.A.T. GOLD San Francisco: May 21-31

Two of the ideas we keep at our core here at Hackaday: the free and open exchange of information and ideas; and “why” is the wrong question. These concepts are fully in line with the F.A.T. Lab. The Free Art and Technology Lab lives at the intersection of Open Source and Pop Culture and they’re inviting you to jump into the pool of awesome by joining them for the F.A.T. Gold Show in San Francisco May 21-31.

If you’re unfamiliar with the group, take a look at the video after the break and you’ll easily confirm that you need to check this out. We’ve enjoyed the work of F.A.T. Lab members for years now. [Brian] pointed out part of the importance of the “Open” aspect the group in this post on universal connectors for popular toy blocks. We also covered their collaboration on EyeWriter which shows how to build IR eye tracking for the disabled. The group hosts the Graffiti Research Labs (also a collaborator on EyeWriter); we built their Laser Graffiti project as part of a live Hackaday event in January of last year thanks to the open source code they published.

What will you see at this year’s show? The best work the group has to offer from the last eight years plus some debut exhibits. We wish we could be there but we’re planning to be in LA that weekend for the LayerOne conference.
