Of Things That Matter Most - 0 views

  • For example, it wasn’t long after astronauts and cosmonauts orbited the earth that they realized ballpoint pens would not work in space. And so some very smart people went to work solving the problem. It took thousands of hours and millions of dollars, but in the end, they developed a pen that could write anywhere, in any temperature, and on nearly any surface. But how did the astronauts and cosmonauts get along until the problem was solved? They simply used a pencil.
  • Let us simplify our lives a little. Let us make the changes necessary to refocus our lives on the sublime beauty of the simple, humble path of Christian discipleship—the path that leads always toward a life of meaning, gladness, and peace.

    Maybe we don't need to drop everything and live in the woods.  We need to take a look at life and prioritize.  We can have a Walden-like experience by simplifying.

Trickle-down Economics and Ronald Reagan - 0 views

  • no significant barrier to the accumulation of wealth by individuals
  • If the rich do well, benefits will "trickle down" to the rest.
  • To qualify as TDE a country must have either a low or flat rate tax on income or only a mildly progressive one (to insure that the rich can continue to get richer, or to trick the poor and middle income people into thinking they can get more and keep it).

  • John Maynard Keynes published his General Theory of Employment, Interest and Money in 1936 and its main thesis was that the federal budget need not always be balanced. Indeed Keynes proposed that the federal government should run a deficit, especially during a recession/depression.

      This presentation really helped my wrap my mind around both special relativity and general relativity. The movies in the presentation do a great job explaining these difficult concepts.

A Logic Named Joe - 1 views

  • Say you punch "Station SNAFU" on your logic. Relays in the tank take over an' whatever vision-program SNAFU is telecastin' comes on your logic's screen. Or you punch "Sally Hancock's Phone" an' the screen blinks an' sputters an' you're hooked up with the logic in her house an' if somebody answers you got a vision-phone connection. But besides that, if you punch for the weather forecast or who won today's race at Hialeah or who was mistress of the White House durin' Garfield's administration or what is PDQ and R sellin' for today, that comes on the screen too.

      Joe disables content filtering services.
  • The screen says, "Service question: What is your name?" She is kinda puzzled, but she punches it. The screen sputters an' then says: "Secretarial Service Demonstration! You—" It reels off her name, address, age, sex, coloring, the amounts of all her charge accounts in all the stores, my name as her husband, how much I get a week, the fact that I've been pinched three times—twice was traffic stuff, and once for a argument I got in with a guy—and the interestin' item that once when she was mad with me she left me for three weeks an' had her address changed to her folks' home. Then it says, brisk: "Logics Service will hereafter keep your personal accounts, take messages, and locate persons you may wish to get in touch with. This demonstration is to introduce the service."

BBC News - The business of innovation: Steven Johnson - 0 views

  • The lone genius, beavering away in the seclusion of his lab is how most of us imagine the great moments of innovation have come into being. But is this really the whole story?
  • "[Good ideas] come from crowds, they come from networks. You know we have this clichéd idea of the lone genius having the eureka moment.
  • "And so much of that is because it's wonderfully set up for other people to build on top of other people's ideas. In many cases without asking for permission.
  • ...4 more annotations...
  • "One of the lessons I've learned is that so many of these great innovators, Darwin is a great example of this, one shared characteristic they all seem to have is a lot of hobbies."
  • So what should companies be doing to foster innovation in their workforces?
  • "I think there's this abiding belief that markets drive innovation, corporations drive innovation, entrepreneurs driven by financial reward drive innovation, and while that's certainly true in many cases there's also this very rich long history of important world-changing ideas coming out of the more or less intellectual commons of the universities.
  • "Go for a walk; cultivate hunches; write everything down; but keep your folders messy; embrace serendipity; make generative mistakes; take on multiple hobbies, frequent coffee houses and other liquid networks; follow the links; let others build on your ideas; borrow, recycle, reinvent."

BBC News - Why companies watch your every Facebook, YouTube, Twitter move - 0 views

  • These days one witty Tweet, one clever blog post, one devastating video - forwarded to hundreds of friends at the click of a mouse - can snowball and kill a product or damage a company's share price.
  • It's a dramatic shift in consumer power. But what if companies could harness this power and turn it to their advantage?
  • At the most basic, these tools measure the volume of social media chatter. Researchers at Hewlett Packard showed that they can accurately predict a Hollywood movie's box office takings by counting how often it is mentioned on Twitter before it opens.

  • One European clothing company, popular with inner city youth in the United States, admits privately that its social media team is baffled by its customers' ever changing slang, and even the online Urban Dictionary provides little help.
  • Social media is quickly becoming a customer relationship management system, as companies have "for the first time access to people's minds in real-time," says Jorn Lyseggen. The tools on offer provide companies with dashboards that show trends, hot topics, the reach of brands, customer mood and how competitors are doing.
  • Social media may be all the buzz, but in reality "only a few firms get it [and use it], it's of peripheral interest for most", says Tom Austin at technology consultancy Gartner. Few realise that using social media has become much more than customer service and reputation management.
  • many social media tools are poorly integrated into the corporate workflow
  • But there are dangers. Financial Times columnist Lucy Kellaway warns that the obsession with social networking can make management lose focus.
  • To survive the world of social media, companies have to throw away their old marketing playbook.
  • "don't push... and don't pretend you are hip"
  • "Once companies have worked out that they should do something with social media, they usually don't know how to do it,"
  • "If you want to influence the people who influence your customers, that's a very powerful game, but it's also very dangerous if you get it wrong."
  • it's not about how many friends or followers somebody has, but whether they make an impact.
  • When Virgin America recently launched new routes from California to Toronto, it used Klout to identify a small group of social media "influencers" and gave them free flights. This generated thousands of tweets, triggered press coverage and delivered more immediate impact than traditional advertising.
  • "Consumers are spending their attention on social media," he says, but firms don't know how to repay them properly. "There's no manual for that yet."
  • Social media are dynamic, and today's Twitter may be tomorrow's forgotten website. "Don't assume that what works today will work tomorrow," says Tom Austin at Gartner. "Your model has to be continually adapted."

  • 1952   Discovery of the area rule of aircraft design Richard Whitcomb, an engineer at Langley Memorial Aeronautical Laboratory, discovers and experimentally verifies an aircraft design concept known as the area rule. A revolutionary method of designing aircraft to reduce drag and increase speed without additional power, the area rule is incorporated into the development of almost every American supersonic aircraft. He later invents winglets, which increase the lift-to-drag ratio of transport airplanes and other vehicles.

  • 1904   Concept of a fixed "boundary layer" described in paper by Ludwig Prandtl German professor Ludwig Prandtl presents one of the most important papers in the history of aerodynamics, an eight-page document describing the concept of a fixed "boundary layer," the molecular layer of air on the surface of an aircraft wing. Over the next 20 years Prandtl and his graduate students pioneer theoretical aerodynamics.
  • 1933   First modern commercial airliner In February, Boeing introduces the 247, a twin-engine 10-passenger monoplane that is the first modern commercial airliner. With variable-pitch propellers, it has an economical cruising speed and excellent takeoff. Retractable landing gear reduces drag during flight.
  • 935   First practical radar British scientist Sir Robert Watson-Watt patents the first practical radar (for radio detection and ranging) system for meteorological applications. During World War II radar is successfully used in Great Britain to detect incoming aircraft and provide information to intercept bombers.
  • 1937   Jet engines designed Jet engines designed independently by Britain’s Frank Whittle and Germany’s Hans von Ohain make their first test runs. (Seven years earlier, Whittle, a young Royal Air Force officer, filed a patent for a gas turbine engine to power an aircraft, but the Royal Air Ministry was not interested in developing the idea at the time. Meanwhile, German doctoral student Von Ohain was developing his own design.) Two years later, on August 27, the first jet aircraft, the Heinkel HE 178, takes off, powered by von Ohain’s HE S-3 engine.
  •   1939   First practical singlerotor helicopters Russian emigre Igor Sikorsky develops the VS-300 helicopter for the U.S. Army, one of the first practical singlerotor helicopters.
