	Differential (mechanics) - WOI Encyclopedia Italia
		In vehicles without a differential, such as karts, both driving wheels are forced to rotate at the same speed, usually on a common axle driven by a simple chain-drive mechanism.
		Vehicles without a center differential should not be driven on dry, paved roads in all wheel drive mode, as small differences in rotational speed between the front and rear of the vehicle cause a torque to be applied across the transmission.
		The oldest known example of a differential, in the Antikythera mechanism, used such a train to produce the difference between two inputs, one input related to the position of the sun on the zodiac, and the other input related to the position of the moon on the zodiac.

	BBTF's Bullpen Mechanics
		Not only does it have good movement and speed differential from his fastball, but what he does best is that he "sells" his changeup.

		What I do want to point out is that his mechanics have changed for the better from last year to this year and he's throwing harder because of it.

	Differential (mechanics)
		In vehicles without a differential, such as karts, both driving wheels are forced to rotate at the same speed, usually on a common axle driven by a simple chain-drive mechanism.
		Another solution is the locking differential, which employs a mechanism for allowing the planetary gears to be locked relative to each other, causing both wheels to turn at the same speed regardless of which has more traction; this is equivalent to removing the differential entirely.
		Vehicles without a center differential should not be driven on dry, paved roads in four wheel drive mode, as small differences in rotational speed between the front and rear wheels cause a torque to be applied across the transmission.

		Tensors, forms, integration and differentiation are all covered, as are curvature and geodesics.

	Geometry from a Differentiable Viewpoint
		Differential geometry is a subject of basic importance for all mathematicians, regardless of their special interests, and it also furnishes essential ideas and tools to physicists and engineers.
		This gave rise to the fruitful idea, due to Gauss and later developed in full generality by Riemann, of dealing with intrinsic differential geometry, that is, to geometrical questions that concern only geometry in the surface as evidenced by the nature of the length measurements on it.
		This is a book for advanced undergraduates carrying ``the reader from the familiar Euclid to the state of development of differential geometry at the beginning of the twentieth century''.

	On the Integration of the N-Body Problem Equations
		In paper [2] we considered the general positions of classical mechanics from the point of view of the the theory of manifold transforms, which represent, in appearance, a geometrical method of solutions of the differential equations of dynamics.
		Yet, precisely in connection with his working up of the theory of differential equations, Euler proved the theorem of elliptical differentials [23], which is a first step towards a general theory of conic sections, setting up a law of their composition as simple events.
		And, in reality, the {projectivization} of a manifold transforms the differential equations of geodesics, the non-linear equations of Newton, to total differentials ([32, 33], {ct.} [34]), (because) the components of integrations are inside the structure of the coordinates, which are given by a complicated proportion [35, 36].

		The new mechanics also permit the optimization of actual, extended shapes within resistive media (such as a wing moving in atmosphere or a body moving in water) via the optimal control isotopic theory, and similar integro- differential problems which cannot evidently be treated via a local-differential mechanics.
		Quantum mechanics is assumed as exact for the conditions of its original conception, the atomic structure and the electroweak interactions at large for matter, while its isodual is under study for a novel treatment of antimatter.
		The isotopic branch of hadronic mechanic is under study to attempt a more realistic representation of the hadronic structure and the strong interactions at large for matter, while its isodual is studied for a novel representation of corresponding antiparticles.

		In the back the power enters the rear differential and is divided between the two transaxles (both are housed inside the rear axle tube), the power then goes into the hub of the wheels and turns the wheel (the rear hubs are always locked).
		Now the problem with open differentials becomes apparent; the two wheels on the top of the gully have a lot of traction and the two in the gully have little or no traction so all the power will go to the wheels with little traction.
		The second is to replace your open differential with a locker, with a locker the problem of lifting a wheel on the trail isn’t such a problem because the wheel on the ground will share the power being sent to the axle with the wheel in the air.

		In an automobile and other wheeled vehicles, a differential is a device for supplying equal torque to the driving wheels, even as they rotate at different speeds.
		Differentials are typically comprised of a gear mechanism in which a ring gear receives input power, which is transferred to two side gears by means of usually two opposing central pinion gears on a common shaft.
		A four-wheel-drive vehicle will have at least two differentials (one for each pair of wheels) and possibly a centre differential to apportion power between the front and rear wheels.

	35: Partial differential equations
		Like ordinary differential equations, partial differential equations are equations to be solved in which the unknown element is a function, but in PDEs the function is one of several variables, and so of course the known information relates the function and its partial derivatives with respect to the several variables.
		Linear differential equations occur perhaps most frequently in applications (in settings in which a superposition principle is appropriate.) When these differential equations are first-order, they share many features with ordinary differential equations.
		For example, integral techniques (solving a differential equation by computing a convolution, say) lead to integral operators (transforms on functions spaces); these and differential operators lead in turn to general pseudodifferential operators on function spaces.

	Geometry and Topology of Fluid Flows
		Researchers in a number of areas of fluid mechanics and MHD are realising that an infusion of mathematical knowledge which is non-traditional in these subjects can greatly enhance their ability to understand and explain the phenomena that they observe.
		The topics fall roughly into four categories: the application of dynamical systems and topology to stirring and chaotic advection, the application of differential geometry to fluid mechanics, the application of topology to magnetic and classical fluid flows, and the application of geometric and topological concepts to the problem of regularity/blowup in hydrodynamics.
		The main goals were to inject ideas from modern differential geometry and topology into fluid mechanics and to inspire new directions in these mathematical fields from discussions on the major problems in fluid mechanics.
