The world's first privately sponsored space launch occurred three days later at Cape Canaveral where Telstar 1 was launched into orbit on top of a Thor-Delta rocket on July 10, 1962. It successfully relayed through space the first television pictures, telephone calls, and telegraph images, and provided the first live transatlantic television feed. http://forums.pelicanparts.com/uploa...1728937142.jpg |

I was being watched on the way home today. Or maybe there's a blind giant muppet somewhere waiting for his eyes to arrive.

The shortest distance between two points is always a straight line, but only in Euclidean geometry. What is this? It's a geometry that is usually taught in school, where figures are two-dimensional and presented on a flat surface like a sheet of paper. In real life, on the surface of the Earth, the shortest distance traveled is a curve called a geodesic. That's because (unfortunately for flat-earthers) our planet is not flat! On the map, the cities of New York and Moscow were used as references. http://forums.pelicanparts.com/uploa...1729028125.jpg |

Inspired by the 1870s penny-farthing bicycle, it features a massive front tractor tire and a smaller rear wheel. Powered by a 60-year-old, 80-hp motor, the bike reaches speeds up to 15 mph (24 km/h). With a steering wheel instead of handlebars and retractable stabilizer wheels, it's a fascinating fusion of creativity and engineering. |

In post 16985, I would take exception to the assertion that planes do not fly in a straight line. A great circle route drawn on a Mercator projection will often exhibit a curve because of the limitations of the medium. However if you take a string and use it to connect two points on a globe, what you see is a perfect depiction of a great circle route.
Now to achieve this, given our method of charting our earth the airplane may have to constantly change headings, but no turns must be made. Best Les http://forums.pelicanparts.com/uploa...1729112712.jpg |

It took thirty Union Pacific freight cars to transport the parts to the mine. Some of the castings weighed ten tons. Assembling the pump at the mine took nearly two years, and was completed late in 1883. A USGS report described the pump: The flywheel was 30 feet in diameter and weighed 70 tons. The pumps were 20 inches in diameter, had a 10-foot stroke, and were capable of throwing 320 gallons of water at each stroke. The pump rod, of Oregon pine, was 1,060 feet long and 16 inches square, and its several sections were united by iron strapping plates 1 by 10 and 1 by 12 inches 30 feet long, The pump lifted 2,560 gallons a minute, 153,600 gallons an hour, or 3,686,400 gallons a day from the 1,000-foot level to the drain tunnel on the 600-foot level. http://forums.pelicanparts.com/uploa...1729113490.jpg |

He is best known for his invention of the first fully functional all-electronic image pickup device (video camera tube), the image dissector, as well as the first fully functional and complete all-electronic television system. He developed a television system complete with receiver and camera—which he produced commercially through the Farnsworth Television and Radio Corporation from 1938 to 1951, in Fort Wayne, Indiana. In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth Fusor, employing inertial electrostatic confinement (IEC). Like many fusion devices, it was not a practical device for generating nuclear power, although it provides a viable source of neutrons. |
