Inside Thomas Edison's Vertically Integrated MegaLab
Thomas Edison was not an inventor for the love of the game. "I always invented to obtain money to go on inventing," he said. For a tireless mind like that, a lab had to be far more than a lab.

Dr. NakaMats: The Man Who Claims to Have Invented Nearly Everything You Love

Does Paul Allen Suing The Entire Internet Prove Our Patent System's Broken?

6 Legends of TV Inventions
There's not much better than a good infomercial-except maybe a really bad one. But these days there's no better innovation hotbed than basic cable paid programming. Here we separate product from pitchman, and celebrate the brains behind As-Seen-On-TV.

Who Invented the Macintosh?
As invention has shifted from the singular genius to the corporate R&D lab, the notion of the true creator has become more slippery. For instance, who invented the Macintosh?

Do Different Languages Equal Different Realities?
We usually assume words are just a way of expressing ideas already in our heads. But what if it's the other way around? Some linguists say the languages we speak fundamentally alter the way we think, and even perceive reality.

Why Failure Is an Option at Intellectual Ventures
Nathan Myhrvold explains why failure is an option at Intellectual Ventures-and it has to be for any inventor, really.

A lot of amazing inventions, ideas, and technologies came about in the 21st century, but we want to know: Which tech invention do you think was the most important during this time?

Rube Goldberg: The Man Behind the Machines
From the maddening board game Mouse Trap to that awesome OK GO video (to the hundreds of brilliant contraptions scattered across YouTube), Rube Goldberg machines continue to enjoy a widespread popularity. But who was Rube Goldberg in the first place?

Inside the Secret Underwater Lake Fort
A Nevada family of scuba divers has prototyped an underwater fort-an anchored air pocket in a net-at the secret location at the bottom of a lake in the Sierras. And it's been there for three years!

MIT's Top 35 Innovators Under 35
As we said in the introductory article for our Eureka theme-week, inventors are either white-haired old men like Edison, or crackpots from infomercials. MIT's Technology Review helps debunk these stereotypes with their 2010 list of the top innovators under 35.

How Kodak Built a FrankenCamera to Take Digital Photos in 1975
During the frigid Rochester winter of 1975, researchers at Kodak pieced together the future a quarter of a century early. Built from scavenged parts, the team had created their first "film-less" camera-an idea far ahead of its time.

Whoops! The 10 Greatest (Accidental) Inventions of All Time
"Everything comes to him who hustles while he waits," Thomas Edison once said. But is hustling all it takes? Is progress always deliberate? Sometimes genius arrives not by choice-but by chance. Below are our ten favorite serendipitous innovations.

Why Ideas Are Expensive
Intellectual Ventures founder and modern day Merlin Nathan Myhrvold explains why it costs a lot of damn money to create new ideas. Hint: Think Hollywood.

Like Most Men, Thomas Edison Enjoyed A Good Catfight
Thomas Edison and his friends were prone to recording short movies for amusement. This particular one reveals how the brilliant inventor is really just like nearly any other man: He just wanted to watch women box.

Nike's Got Back to the Future II Sneaker Patents

Prototype Robot Swarm Could Clean Up Oil Spill in a Month

How Intellectual Ventures Wants to Reinvent Invention

Eureka: Hello Invention
Once upon a time, "inventor" was an honest-to-god occupation. You could check a box, and tell the U.S. Census Bureau that's what you were. Now, inventors are as-seen-as-on-TV caricatures and "innovation" is a corporate-speak. We want to celebrate invention. Eureka.
