(p. 2) Michio Kaku is a theoretical physicist and professor at City College of New York. When not trying to complete Einstein’s theory of everything, he writes books that explain physics and how developments in the field will shape the future.
. . .
One of the most intriguing things I’ve read lately was by Miguel Nicolelis, called “Beyond Boundaries: The New Neuroscience of Connecting Brains With Machines,” in which he describes hooking up the brain directly to a computer, which allows you to mentally control a robot or exoskeleton on the other side of the earth.

Khan’s Cousins Liked Him Better on YouTube than in Person

(p. D5) In 2008, Salman Khan, then a young hedge-fund analyst with a master’s in computer science from M.I.T., started the Khan Academy, offering free online courses mainly in the STEM subjects — science, technology, engineering and mathematics.

Today the free electronic schoolhouse reaches more than 10 million users around the world, with more than 5,000 courses, and the approach has been widely admired and copied. I spoke with Mr. Khan, 37, for more than two hours, in person and by telephone. What follows is a condensed and edited version of our conversations.
. . .
Did you have background as a math educator?
No, though I’ve had a passion for math my whole life. It got me to M.I.T. and enabled me to get multiple degrees in math and engineering. Long story shortened: Nadia got through what she thought she couldn’t. Soon word got around the family that “free tutoring” was going on, and I found myself working on the phone with about 15 cousins.
To make it manageable, I hacked together a website where my cousins could go to practice problems and I could suggest things for them to work on. When I’d tutor them over the telephone, I’d use Yahoo Doodle, a program that was part of Yahoo Messenger, so they could visualize the calculations on their computers while we talked.
The Internet videos started two years later when a friend asked, “How are you scaling your lessons?” I said, “I’m not.” He said, “Why don’t you make some videos of the tutorials and post them on YouTube?” I said, “That’s a horrible idea. YouTube is for cats playing piano.”
Still, I gave it try. Soon my cousins said they liked me more on YouTube than in person. They were really saying that they found my explanations more valuable when they could have them on demand and where no one would judge them. And soon many people who were not my cousins were watching. By 2008, I was reaching tens of thousands every month.
Youtube is a search engine where producers can upload short videos at no cost. Would the Khan Academy have been possible without this technology?
No. Before YouTube, the cost of hosting streaming videos was incredibly expensive. I wouldn’t have been able to afford the server space for that much video — or traffic. That said, I was probably the 500th person to show up on YouTube with educational videos. Our success probably had to do with the technology being ready and the fact that my content resonated with users.

Catmull’s Pixar Had Technology Serve Story

Ed Catmull, one of the creators of Pixar, discusses a favorite book of 2013. Catmull’s appreciation of the importance of storytelling may help explain why the early Pixar movies were so wonderful:

(p. C6) I am constantly struck by how many people think of stories solely as entertainment–edifying or time-wasting but still: entertainment. “The Storytelling Animal” by Jonathan Gottschall shows that the storytelling part of our brain is deeper and more complex than that, wired into the way we think and learn. This struck me as a powerful idea, that our brain is structured for and shaped by stories whose value goes beyond entertainment and socialization.

Hero Rebels Against the Bureau of Technology Control

InfluxBK2014-02-19.jpg

Source of book image: online version of the WSJ review quoted and cited below.

(p. D8) In “Influx,” . . . , a sinister Bureau of Technology Control kidnaps scientists that have developed breakthrough technologies (the cure to cancer, immortality, true artificial intelligence), and is withholding their discoveries from humanity, out of concern over the massive social disruption they would cause. “We don’t have a perfect record–Steve Jobs was a tricky one–but we’ve managed to catch most of the big disrupters before they’ve brought about uncontrolled social change,” says the head of the bureau, the book’s villain. The hero has developed a “gravity mirror” but refuses to cooperate, despite the best efforts of Alexa, who has been genetically engineered by the Bureau to be both impossibly sexy and brilliant.

In the publishing world, there is a growing sense that “Influx,” Mr. Suarez’s fourth novel, may be his breakout book and propel him into the void left by the deaths of Tom Clancy and Michael Crichton. “Influx’ has Mr. Suarez’s largest initial print run, 50,000 copies, and Twentieth Century Fox bought the movie rights last month.
An English major at the University of Delaware with a knack for computers, Mr. Suarez started a consulting firm in 1997, working with companies like NestlĂ© on complex production and logistics-planning issues. “You only want to move 100 million pounds of sugar once,” says Mr. Suarez, 49 years old.
He began writing in his free-time. Rejected by 48 literary agents–(a database expert, he kept careful track)–he began self-publishing in 2006 under the name Leinad Zeraus, his named spelled backward. His sophisticated tech knowledge quickly attracted a cult following in Silicon Valley, Redmond, Wash., and Cambridge, Mass. The MIT bookstore was the first bookstore to stock his self-published books in 2007.

It Does Not Take a Government to Raise a Railroad

(p. A17) . . . , All Aboard Florida (the train will get a new name this year), is not designed to push political buttons. It won’t go to Tampa. It will zip past several aggrieved towns on Florida’s Treasure Coast without stopping.
Nor will the train qualify as “high speed,” except on a stretch where it will hit 125 miles an hour. Instead of running on a dedicated line, the new service will mostly share existing track with slower freight trains operated by its sister company, the Florida East Coast Railway.
But the sponsoring companies, all owned by the private-equity outfit Fortress Investment Group, appear to have done their sums. By minimizing stops, the line will be competitive with road and air in connecting the beaches, casinos and resorts of Miami and Fort Lauderdale with the big airport and theme-park destination of Orlando. Capturing a small percentage of the 50 million people who travel between these fleshpots, especially European visitors accustomed to intercity rail at home, would let the train cover its costs and then some.
But Fortress has a bigger fish in the pan. Its local operation, Florida East Coast Industries, is a lineal progeny of Henry Flagler, the 1890s entrepreneur who created modern Florida when he built a rail line to support his resort developments. Flagler’s heirs are adopting the same model. A Grand Central-like complex will rise on the site of Miami’s old train station. A similar but smaller edifice is planned for Fort Lauderdale.
The project is a vivid illustration of the factors that have to fall in place to make passenger rail viable nowadays. If the Florida venture succeeds, it would be the only intercity rail service anywhere in the world not dependent on government operating subsidies. It would be the first privately run intercity service in America since the birth of Amtrak in 1971.

70 Percent of Current Jobs May Soon Be Done by Robots

Kelly may be right, but it does not imply that we will all be unemployed. What will happen is that new and better jobs, and entrepreneurial opportunities, will be created for humans.
Robots will do the boring, the dangerous, and the physically exhausting. We will do the creative and the analytic, and the social or emotional

(p. A21) Kevin Kelly set off a big debate with a piece in Wired called “Better Than Human: Why Robots Will — And Must — Take Our Jobs.” He asserted that robots will soon be performing 70 percent of existing human jobs. They will do the driving, evaluate CAT scans, even write newspaper articles. We will all have our personal bot to get coffee. There’s already an existing robot named Baxter, who is deliciously easy to train: “To train the bot you simply grab its arms and guide them in the correct motions and sequence. It’s a kind of ‘watch me do this’ routine. Baxter learns the procedure and then repeats it. Any worker is capable of this show-and-tell.”

Carnegie Failed Twice Before Bessemer Success

(p. 101) [Carnegie] . . . organized his own company to secure the rights to the Dodd process for strengthening iron rails by coating them with steel facings. Thomson agreed to appropriate $20,000 of Pennsylvania Railroad funds to test the new technology.
On March 12, 1867, Thomson wrote to tell Carnegie that his Dodd-processed rails had failed their first test: “treatment under the hammer…. You may as well abandon the Patent–It will not do if this Rail is a sample.” Three days later, Thomson wrote Carnegie again, this time marking his letter with a handwritten “Private” in the top left-hand corner and “a word to the wise” penned in just below. Carnegie had apparently asked Thomson for more time–and/or money–to continue his experiments. Thomson replied that the experiments his engineers had made had so “impaired my confidence in this process that I don’t feel at liberty to increase our order for these Rails.”
Instead of giving up, Carnegie pushed forward, hawking his new steel-faced iron rails to other railroad presidents, attempting to get a new contract with Thomson, and reorganizing the Freedom Iron Company in Lewistown, Pennsylvania, in which he was a major investor, into Freedom Iron and Steel. In the spring of 1867, he succeeded, despite Thomson’s misgivings, in getting the approval to manufacture and deliver a second 500-ton batch of steel-faced rails. The new rails fared as poorly as the old ones. There would be no further contracts forthcoming from the Pennsylvania Railroad or any other railroad.
Carnegie tried to bluff his way through. When his contacts in England recommended that he purchase the American rights to a better process for facing iron rails with steel, this one invented by a Mr. Webb, Carnegie retooled his mill for the new process. He was fooled a second time. Not only was the Webb process as impractical as the Dodd, but there was, as there (p. 102) had been with the Dodd process, confusion as to who held the American patent rights. Within a year, the company Carnegie had organized to produce the new steel-faced rails was out of business.
. . .
These early failures did not deter him from investing in other start-up companies and technologies, but he would in future be a bit more careful before committing his capital. In March 1869, Tom Scott solicited his advice about investing in the rights to a new “Chrome Steel process.” Carnegie replied that his “advice (which don’t cost anything if of no value) would be to have nothing to do with this or any other great change in the manufacture of steel or iron…. I know at least six inventors who have the secret all are so anxiously awaiting…. That there is to be a great change in the manufacture of iron and steel some of these years is probable, but exactly what form it is to take no one knows. I would advise you to steer clear of the whole thing. One will win, but many lose and you and I not being practical men would very likely be among the more numerous class. At least we would wager at very long odds. There are many enterprises where we can go in even.”

READING I just started “David and Goliath,” by Malcolm Gladwell. He has some really interesting statistics about how at the top-tier universities like Stanford and Harvard, freshmen who go into engineering often fall out versus if those same students had gone to a second-tier school, they would have been in the top of their class and therefore would have stayed in. It really spoke to me because I was definitely one of those engineering students at Stanford who constantly felt like I was surrounded by geniuses. I was intimidated, but I stayed because I am just so stubborn.

In 20th Century, Inventions Had Cultural Impact Twice as Fast as in 19th Century

NgramGraphTechnologies2013-12-08.png I used Google’s Ngram tool to generate the Ngram above, using the same technologies used in the Ngram that appeared in the print (but not the online) version of the article quoted and cited below. The blue line is “railroad”; the red line is “radio”; the green line is “television”; the orange line is “internet.” The search was case-insensitive. The print (but not the online) version of the article quoted and cited below, includes a caption that describes the Ngram tool: “A Google tool, the Ngram Viewer, allows anyone to chart the use of words and phrases in millions of books back to the year 1500. By measuring historical shifts in language, the tool offers a quantitative approach to understanding human history.”

(p. 3) Today, the Ngram Viewer contains words taken from about 7.5 million books, representing an estimated 6 percent of all books ever published. Academic researchers can tap into the data to conduct rigorous studies of linguistic shifts across decades or centuries. . . .
The system can also conduct quantitative checks on popular perceptions.
Consider our current notion that we live in a time when technology is evolving faster than ever. Mr. Aiden and Mr. Michel tested this belief by comparing the dates of invention of 147 technologies with the rates at which those innovations spread through English texts. They found that early 19th-century inventions, for instance, took 65 years to begin making a cultural impact, while turn-of-the-20th-century innovations took only 26 years. Their conclusion: the time it takes for society to learn about an invention has been shrinking by about 2.5 years every decade.
“You see it very quantitatively, going back centuries, the increasing speed with which technology is adopted,” Mr. Aiden says.
Still, they caution armchair linguists that the Ngram Viewer is a scientific tool whose results can be misinterpreted.
Witness a simple two-gram query for “fax machine.” Their book describes how the fax seems to pop up, “almost instantaneously, in the 1980s, soaring immediately to peak popularity.” But the machine was actually invented in the 1840s, the book reports. Back then it was called the “telefax.”
Certain concepts may persevere, even as the names for technologies change to suit the lexicon of their time.
