On September 30, 2011 at 11:08am, Derek Deville's Qu8k (pronounced "Quake") launched from the Black Rock Desert in Nevada to an altitude of 121,000' before returning safely to earth. Above 99% of the atmosphere, the sky turns black in the middle of the day and the curvature of the earth is clearly visible. The rocket motor produced 4,000 lbs of thrust for 8 seconds accelerating the vehicle to over Mach 3 at over 10,000'. After that, momentum carried the rocket skyward for another 84 seconds to a peak altitude of 121,000'.
How to get an 80' rig through the 65' bridges of the Intracoastal Waterway using two tons of water. The balls get swung out with an initial turn to port or stbd. The tendency then is for the roll to continue by itself, but is controlled by letting the bags out slowly with a line made off to each bag and running through necessary tackle to a cockpit winch.

This is a hard drive clock I built from a 3.5" hard drive, some tri-color LEDs and a PIC16F252 microcontroller. It works by shining the LEDs underneath a platter with a slot cut into it, and by timing the various colors it can produce an analog clock display as well as other patterns.
"The Grand Rapids LipDub Video was filmed May 22nd, with 5,000 people, and involved a major shutdown of downtown Grand Rapids, which was filled with marching bands, parades, weddings, motorcades, bridges on fire, and helicopter take offs. It is the largest and longest LipDub video, to date.
This video was created as an official response to the Newsweek article calling Grand Rapids a "dying city." We disagreed strongly, and wanted to create a video that encompasses the passion and energy we all feel is growing exponentially, in this great city. We felt Don McLean's "American Pie," a song about death, was in the end, triumphant and filled to the brim with life and hope." - Rob Bliss, Director & Executive Producer

In 2001, former president Bill Clinton delivered a speech at Georgetown University in which he discussed the West’s response to the recent terrorist attacks of September 11. The speech contained a short but significant reference to the crusades. Mr. Clinton observed that “when the Christian soldiers took Jerusalem [in 1099], they . . . proceeded to kill every woman and child who was Muslim on the Temple Mount.” He cited the “contemporaneous descriptions of the event” as describing “soldiers walking on the Temple Mount . . . with blood running up to their knees.” This story, Mr. Clinton said emphatically, was “still being told today in the Middle East and we are still paying for it.”Read the whole thing here.
This view of the crusades is not unusual. It pervades textbooks as well as popular literature. One otherwise generally reliable Western civilization textbook claims that “the Crusades fused three characteristic medieval impulses: piety, pugnacity, and greed. All three were essential.”1 The film Kingdom of Heaven (2005) depicts crusaders as boorish bigots, the best of whom were torn between remorse for their excesses and lust to continue them. Even the historical supplements for role-playing games—drawing on supposedly more reliable sources—contain statements such as “The soldiers of the First Crusade appeared basically without warning, storming into the Holy Land with the avowed—literally—task of slaughtering unbelievers”;2 “The Crusades were an early sort of imperialism”;3 and “Confrontation with Islam gave birth to a period of religious fanaticism that spawned the terrible Inquisition and the religious wars that ravaged Europe during the Elizabethan era.”4 The most famous semipopular historian of the crusades, Sir Steven Runciman, ended his three volumes of magnificent prose with the judgment that the crusades were “nothing more than a long act of intolerance in the name of God, which is the sin against the Holy Ghost.”5
The verdict seems unanimous. From presidential speeches to role-playing games, the crusades are depicted as a deplorably violent episode in which thuggish Westerners trundled off, unprovoked, to murder and pillage peace-loving, sophisticated Muslims, laying down patterns of outrageous oppression that would be repeated throughout subsequent history. In many corners of the Western world today, this view is too commonplace and apparently obvious even to be challenged.
But unanimity is not a guarantee of accuracy. What everyone “knows” about the crusades may not, in fact, be true. From the many popular notions about the crusades, let us pick four and see if they bear close examination. ...
Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and (seemingly) random motion.
...
The period of one complete cycle of the dance is 60 seconds. The length of the longest pendulum has been adjusted so that it executes 51 oscillations in this 60 second period. The length of each successive shorter pendulum is carefully adjusted so that it executes one additional oscillation in this period. Thus, the 15th pendulum (shortest) undergoes 65 oscillations. ...
