In medieval and ancient philosophy, the Wheel of Fortune or Rota Fortunae is a symbol of the capricious nature of Fate. The wheel belongs to the goddess Fortuna ( Greek equivalent: Tyche ) who spins it at random, changing the positions of those on the wheel: some suffer great misfortune, others gain windfalls.
Early designs of perpetual motion machines were done by Indian mathematician–astronomer Bhaskara II, who described a wheel (Bhāskara's wheel) that he claimed would run forever. [2] A drawing of a perpetual motion machine appeared in the sketchbook of Villard de Honnecourt, a 13th-century French master mason and architect.
The Spinning Wheel is also the title/subject of a classic Irish folk song by John Francis Waller. [51] [52] A traditional Irish folk song, Túirne Mháire, is generally sung in praise of the spinning wheel, [53] but was regarded by Mrs Costelloe, who collected it, [54] as "much corrupted", and may have had a darker narrative. It is widely ...

WHEE-LO is a trademark for a handheld toy that propels a plastic wheel along both sides of a metal track with magnets built into the wheel. As the track is tilted up and down, the wheel rolls the length of the track, top and bottom, and then again on the opposite side of the wire.
The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly than the true rotation, it can appear stationary, or it can appear to rotate in the opposite direction from the true rotation ...
Random.org (stylized as RANDOM.ORG) is a website that produces random numbers based on atmospheric noise. [1] In addition to generating random numbers in a specified range and subject to a specified probability distribution, which is the most commonly done activity on the site, it has free tools to simulate events such as flipping coins, shuffling cards, and rolling dice.
The wheel shows a tendency to align its spin axis with the axis of rotation (the gimbal axis), and it is this action which rotates the entire vehicle about its roll axis. Ideally, the mechanism applying control torques to the gimbal ought to be passive (an arrangement of springs , dampers and levers ), but the fundamental nature of the problem ...
