      I love helicopters!  But I never knew that they had been around for so many years.
  • 1947   Sound barrior broken U.S. Air Force pilot Captain Charles "Chuck" Yeager becomes the fastest man alive when he pilots the Bell X-1 faster than sound for the first time on October 14 over the town of Victorville, California.
  • 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.
  •   1917   The Junkers J4, an all-metal airplane, introduced Hugo Junkers, a German professor of mechanics introduces the Junkers J4, an all-metal airplane built largely of a relatively lightweight aluminum alloy called duralumin.
  • 1925-1926   Introduction of lightweight, air-cooled radial engines The introduction of a new generation of lightweight, air-cooled radial engines revolutionizes aeronautics, making bigger, faster planes possible.
  • 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.

    I'm not sure that this is how most people use tumblr, but it occured to me that searching for images through a blogging service where people are handpicking these images may be a better system. How many of us have looked something up through google images with sheer frustration at the lack of variety of images? Maybe I'm the only one. All I'm saying is that you should try opening up tumblr, plugging in a word like "mountains" or something and see what rolls out. Keep in mind that an extract of the blogger's text entry is displayed with the image, so it is not a legitimate "image search." But I really feel that this way of people deciding what images should be showing up is a great one. That is all. Also--Don't get too distracted by the huge sign up form in the middle of the page.

      Of course they want mess with the data, other wise the fundung companies pulls out from under you...
  • However, whether consciously or subconsciously, the danger is that these data may sometimes be interpreted in a certain, more favourable, light.

The best art is born from democracy - 0 views

  •  
    An interesting article. I believe this is true. Think of the wide range of art in the world today. This also has a great deal to due with technology and the ability to share images, of course. Democracy itself has allowed art to blossom and allowed the visual expression to become quite a personal thing.

  • principle of accountability also applies to the spiritual resources conferred in the teachings we have been given and to the precious hours and days allotted to each of us during our time in mortality.
  • The significance of our increased discretionary time has been magnified many times by modern data-retrieval technology. For good or for evil, devices like the Internet and the compact disc have put at our fingertips an incredible inventory of information, insights, and images. Along with fast food, we have fast communications and fast facts. The effect of these resources on some of us seems to fulfill the prophet Daniel’s prophecy that in the last days “knowledge shall be increased” and “many shall run to and fro”
  • homely story

  • “Do you think we need a bigger truck?”
  • our biggest need is a clearer focus on how we should value and use what we already have.
  • But to what purpose?
  • “knowledge of words, and ignorance of the Word,” in which “wisdom” is “lost in knowledge” and “knowledge” is “lost in information”
  • We have thousands of times more available information than Thomas Jefferson or Abraham Lincoln. Yet which of us would think ourselves a thousand times more educated or more serviceable to our fellowmen than they?
  • I could never complete my assigned task within the available time unless I focused my research in the beginning and stopped that research soon enough to have time to analyze my findings and compose my conclusions.
  • we must begin with focus or we are likely to become like those in the well-known prophecy about people in the last days—“ever learning, and never able to come to the knowledge of the truth” (2 Tim. 3:7).
  • But a bale of handouts can detract from our attempt to teach gospel principles with clarity and testimony.
  • Stacks of supplementary material can impoverish rather than enrich, because they can blur students’ focus on the assigned principles and draw them away from prayerfully seeking to apply those principles in their own lives.
  • Each of us should be careful that the current flood of information does not occupy our time so completely that we cannot focus on and hear and heed the still, small voice that is available to guide each of us with our own challenges today.
  • Our priorities determine what we seek in life.
  • “a man’s life consisteth not in the abundance of the things which he possesseth”
  • Our priorities are most visible in how we use our time.
  • Good choices are especially important in our family life. For example, how do family members spend their free time together? Time together is necessary but not sufficient.
  • I believe many of us are overnourished on entertainment junk food and undernourished on the bread of life.

    Available information wisely used is far more valuable than multiplied information allowed to lie fallow.

Uh-merican: Pet Rocks - 0 views

  • Only in America could a guy like Dahl take advantage of so many people. I know I have probably paid for dumb things in my lifetime, like Keds shoes or canned beets, but seriously, a rock?

    Have you ever heard of pet rocks? Thinking about FarmVille and all the services you pay actual money for online for virtual things made me think of them. Check out this blog post about them, and tell me it's not ridiculous.

The Crystal Palace/ The Great Exhibition of 1851 - 0 views

  • Over 13,000 exhibits were displayed and viewed by over 6,200,000 visitors to the exhibition.
  • The London Borough of Bromley, who own the park today, together with the Crystal Palace Foundation, have recently submitted an outline proposal the National Heritage Lottery Fund to restore much of the park to its former glory.
  • The Crystal Palace itself was destroyed by fire on  November 30th 1936, following which the area lost much of its focus and began to decline. But many of the most important events in the history of the Crystal Palace took place in the grounds, which retain much of their original overall layout today and are a Grade II listed historic park.
  • ...4 more annotations...
  • The park also contained unrivaled collections of statues, many of which were copies of great works from around the world, and a geological display which included a replica lead mine and the first attempts anywhere in the world to portray life-size restorations of extinct animals, including dinosaurs.
  • This "bigger and better" building was divided into a series of courts depicting the history of art and architecture from ancient Egypt through  the Renaissance, as well as exhibits from industry and the natural world.
  • The Crystal Palace was originally designed by Sir Joseph Paxton in only 10 days and was a huge iron goliath with over a million feet of glass.
  • The Great Exhibition of 1851 in London was conceived to symbolize this industrial, military and economic superiority of Great Britain.

Future Shock Re-assessed by Richard Slaughter - 2 views

  • both individuals and societies needed to learn how to adapt to and manage the sources of over-rapid change.
  • Possibly the best section in the book is that on education. Here he advanced a powerful critique: ‘what passes for education today, even in our ‘best’ schools and colleges, is a hopeless anachronism.’ He then added: for all this rhetoric about the future, our schools face backwards towards a dying system, rather than forwards to an emerging new society. Their vastenergies are applied to cranking out Industrial Men - people tooled for survival in a system that will be dead before they are. (2) The thesis was then advanced that the prime objective of education should be to ‘increase the individual’s ‘cope-ability’ - the speed and economy with which he can adapt to continual change.’ (3) Central to this was ‘the habit of anticipation’. Assumptions, projections, images of futures would need to become part and parcel of every individual’s school experience.
