He demonstrated his principle using vector space geometry based on an “ orthogonality condition ” which only worked in systems where the velocities were defined as a single vector or tensor, and thus, as he wrote at p. 347, was “ impossible to test by means of macroscopic mechanical models ”, and was, as he pointed out, invalid in “ compound systems where several elementary processes take place simultaneously ”.

This is because of the vector addition properties of quantum mechanical angular momenta, and because light particles ( photons ) have angular momenta of 1.

The LRL vector was essential in the first quantum mechanical derivation of the spectrum of the hydrogen atom, before the development of the Schrödinger equation.

A subtlety of the quantum mechanical operator for the LRL vector A is that the momentum and angular momentum operators do not commute ; hence, the cross product of p and L must be defined carefully.

From a mechanical viewpoint, up to 99 % of the energy delivered by the rider into the pedals is transmitted to the wheels, although the use of gearing mechanisms may reduce this by 10 – 15 %.

Eversharp, a maker of mechanical pencils, teamed up with Eberhard Faber in May 1945 to license the design for sales in the United States.

The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and unifies its contents from the cellular cytoplasm, and the nucleoskeleton ( which includes nuclear lamina ), a meshwork within the nucleus that adds mechanical support, much like the cytoskeleton, which supports the cell as a whole.

With a rigid mechanical linkage, smooth engagement would be near-impossible because engine movement inevitably occurs as the drive is " taken up.

The tower is made up of three sections: a 30. 5 m ( 100 ft ) high tower base forming the main entrance and public circulation spaces ; a 235. 4 m ( 772 ft ) tall tower body containing 57 office floors, a sky lobby and five mechanical plant floors ; and the tower top consist of six mechanical plant floors and a 102 m ( 335 ft ) tall tower mast.

At one time, Pressman Toys manufactured a product called Domino Rally that contained tiles and mechanical devices for setting up toppling exhibits.

The quantum mechanical nature of this spin causes the electron to only be able to be in two states, with the magnetic field either pointing " up " or " down " ( for any choice of up and down ).

Pickups are transducers attached to a guitar that detect ( or " pick up ") string vibrations and convert the mechanical energy of the string into electrical energy.

This type of glass-ceramic exhibits excellent mechanical properties and can sustain repeated and quick temperature changes up to 1000 ° C.

Aside from written numerals, the first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic operation, then manipulate the device to obtain the result.

However, up to the 1940s, many subsequent designs ( including Charles Babbage's machines of the 1822 and even ENIAC of 1945 ) were based on the decimal system ; ENIAC's ring counters emulated the operation of the digit wheels of a mechanical adding machine.

Materials demand is driven by substrates, making up over 70 percent of the market, packaging coatings and increasing use of chemical mechanical planarization ( CMP ).

Therefore some magnetos have an impulse coupling, a springlike mechanical linkage between the engine and magneto drive shaft which " winds up " and " lets go " at the proper moment for spinning the magneto shaft.

Positive displacement pumps physically displace the fluid ; hence closing a valve downstream of a positive displacement pump will result in a continual build up in pressure resulting in mechanical failure of either pipeline or pump.

Therefore, kyanite is often the preferred material, as it contributes both mechanical strength and, in amounts up to 20 %, significantly reduces thermal expansion.

* Deprecation of the Aristotelian theory that matter was continuous and made up of the elements Earth, Water, Air, and Fire because its classic rival, Atomism, better lent itself to a " mechanical philosophy " of matter.

In addition to Salmon's model, others have suggested that explanation is primarily motivated by unifying disparate phenomena or primarily motivated by providing the causal or mechanical histories leading up to the phenomenon ( or phenomena of that type ).

The game features the cities, parks, and suburbs of the Vorticons, and their women, children, pets, and mechanical toys make up the enemies.

CATIA enables the creation of 3D parts, from 3D sketches, sheetmetal, composites, molded, forged or tooling parts up to the definition of mechanical assemblies.

To the end of his life Cumming retained an infectious, if sometimes eccentric, enthusiasm for the tradecraft and mystification of espionage, experimenting personally with disguises, mechanical gadgets, and secret inks in his own laboratory.

CFAP is characterized by chronic pain, with no physical explanation or findings ( no structural, infectious, or mechanical causes can be found ).

The washing process whereby soils are removed consists basically of applying mechanical action to loosen the dirt particles and dried matter in the presence of water which helps to float off the debris and acts, to some extent, as a dissolving and solvating agent.

In a few years ( 1939 ) Turing would propose, like Church and Kleene before him, that his formal definition of mechanical computing agent was the correct one.

Jules Verne, in From the Earth to the Moon, published in 1865, wrote " there will some day appear velocities far greater than these the planets and the projectile, of which light or electricity will probably be the mechanical agent ... we shall one day travel to the moon, the planets, and the stars.

Pleyel essentially acted as his agent in collecting mechanical royalties for his works and provided him with a monthly income and a studio space at its headquarters in which he could work and entertain friends and business acquaintances.

With each of these processes, oil and a reclaiming agent are added to the reclaimed rubber powder, which is subjected to high temperature and pressure for a long period ( 5 – 12 hours ) in special equipment and also requires extensive mechanical post-processing.

The leavening agent incorporates gas bubbles into the dough — this may be air incorporated by mechanical means, but usually it is carbon dioxide produced by biological agents, or by chemical agents reacting with moisture, heat, acidity, or other triggers.
