A gyroscope (from Greek γῦρος gûros, "circle" and σκοπέω skopéō, "to look") is a spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. Because of this, gyroscopes are useful for measuring or maintaining orientation.
Gyroscopes based on other operating principles also exist, such as the electronic, microchip-packaged MEMS gyroscopes found in consumer electronics devices, solid-state ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope.
Applications of gyroscopes include inertial navigation systems where magnetic compasses would not work (as in the Hubble telescope) or would not be precise enough (as in intercontinental ballistic missiles), or for the stabilization of flying vehicles like radio-controlled helicopters or unmanned aerial vehicles, and recreational boats and commercial ships. Due to their precision, gyroscopes are also used in gyrotheodolites to maintain direction in tunnel mining. Gyroscopes can be used to construct gyrocompasses, which complement or replace magnetic compasses (in ships, aircraft and spacecraft, vehicles in general), to assist in stability (Hubble Space Telescope, bicycles, motorcycles, and ships) or be used as part of an inertial guidance system.
A hydraulic press is a device (see machine press) using a hydraulic cylinder to generate a compressive force. It uses the hydraulic equivalent of a mechanical lever, and was also known as a Bramah press after the inventor, Joseph Bramah, of England. He invented and was issued a patent on this press in 1795. As Bramah (who is also known for his development of the flush toilet) installed toilets, he studied the existing literature on the motion of fluids and put this knowledge into the development of the press.
The hydraulic press depends on Pascal's principle: the pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force. Only small-diameter tubing (which more easily resists pressure) is needed if the pump is separated from the press cylinder.
Pascal's law: Pressure on a confined fluid is transmitted undiminished and acts with equal force on equal areas and at 90 degrees to the container wall.
Vacuum is space void of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object as being in what would otherwise be a vacuum.
The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. Much higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (10−12) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm3.Outer space is an even higher-quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average. According to modern understanding, even if all matter could be removed from a volume, it would still not be "empty" due to vacuum fluctuations, dark energy, transiting gamma rays, cosmic rays, neutrinos, and other phenomena in quantum physics. In the electromagnetism in the 19th century, vacuum was thought to be filled with a medium called aether. In modern particle physics, the vacuum state is considered the ground state of matter.
Why does a gyroscope not turn in the direction you push it? Seeing the equations that tell me this is not satisfying to me. I have found a way to think about it that allows me to sleep at night.

It continues to fascinate young and old alike with its mysterious force that seems to defy gravity. It can even dance on a tightrope or balance on the lip of a glass. Discover the secret and make your gyroscope do these and other astounding tricks. This is an excellent tool to teach gyroscopic inertia and teaches a physical principle of the conservation of angular momentum. Gyroscope technology is used in numerous applications of everyday life such as in bicycles, levitating tops, satellites and navigation systems of airplanes and space shuttles.

NOTE: This video will appear in a playlist on Smarter Every Day hence the references to Veritasium. Destin does lots of cool science stuff - check out his channel if you haven't already http://www.youtube.com/destinws2 We have been collaborating on rotational motion, which is timely for some of the videos I've been doing lately. In this video I talk about gyroscopic precession - the "wobbling" of a spinning top around its axis. This is caused by the torque due to the object's weight. The big idea is that the torque vector increases angular momentum in the direction of torque. So if there is no angular momentum initially, it will cause the system to swing in such a direction that it is rotating with new angular momentum in the direction of the torque. However, if there was angular mom...

Ralph and the School of Physics. In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it's spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was 'light as a feather' and could not be explained by Newton's Laws.

In this video I put a levitating gyroscope in the vacuum chamber to see if it will spin forever without any air resistance. This has been requested many times by my viewers, and I have always wondered what happens to a levitating spinning disk in a vacuum chamber. I show you how the levitation woks and I also give you some tips on how to do it if you get one of these levitating disks.

Update: main components are listed at the bottom of this description. This is my first attempt to build gyro-stabilized system for 2-inline-wheeled platform. I use model steam engine flywheel for the gyroscope, door hinge as steering unit and wheels from inline skates. I'm planning to add some motors for active gyro controlling, forward-backward motion and steering. At this point this thing would not stand by itself for a long period of time. I need to add an active gyro control system. The gyroscope natural movement (swing) you see on video is the precession. By actively control the gimbal (manipulating precession), maybe I can get better stability.

GYROSCOPIC TRANSPORTATION OF THE FUTURE amazing concept from DAHİR İNŞAAT highlights what could possibly be the future of transport. this was designed for the urban commuter looking for an entirely new and unique driving experience. With just two wheels, the glass-dome cabin is self-balancing and can be controlled with a joystick instead of a steering wheel. This has a huge potential to provide an efficient, economical, safe, environmentally friendly, comfortable, and maneuverable conveyance that is independent of the general traffic flows on arterial roads. That is because the lane separator between lanes satisfies all of the requirements for the creation of this mode of transportation. It will inevitably take its rightful place as a modern urban form of transportation. It is just simply...

It was a hell of a climb
and I swear that I searched everywhere but I'm damned if I could find
your promise ring
Like a candle in the window
I was waiting till the cold winds blow
I did ten years for my crime.
So tonight I think I'll just take my time... for tonight I sing of big and better things.
I best sing before the lights go out.
Time.
Sing before the lights go out.
Time.
I share no secrets. I know you won't keep them anyway.
Hate kills time and time kills haters
They look good but I feel greater hey.
No way
