  8. Etymology: [Cf. F. diffrentiel.]


  1. Differential

    A differential is a device, usually, but not necessarily, employing gears, which is connected to the outside world by three shafts, chains, or similar, through which it transmits torque and rotation. The gears or other components make the three shafts rotate in such a way that, where, and are the angular velocities of the three shafts, and and are constants. Often, but not always, and are equal, so is proportional to the sum of and . Except in some special-purpose differentials, there are no other limitations on the rotational speeds of the shafts, apart from the usual mechanical/engineering limits. Any of the shafts can be used to input rotation, and the other to output it. See animation of a simple differential in which and are equal. The shaft rotating at speed is at the bottom-right of the image. In automobiles and other wheeled vehicles, a differential is the usual way to allow the driving roadwheels to rotate at different speeds. This is necessary when the vehicle turns, making the wheel that is travelling around the outside of the turning curve roll farther and faster than the other. The engine is connected to the shaft rotating at angular velocity . The driving wheels are connected to the other two shafts, and and are equal. If the engine is running at a constant speed, the rotational speed of each driving wheel can vary, but the sum of the two wheels' speeds can not change. An increase in the speed of one wheel must be balanced by an equal decrease in the speed of the other.

    This is the law that all life evolves by the differential survival of replicating entities.

  2. Patti Perez:

    For me, the biggest message from this, if I were Patti Perez or if I were Patti Perez, is that the days of having layers of structure in place that exacerbate that power differential between an employer and an employee need to kind of go away, i think that especially the new generation of workers that are coming into the workplace, there's just going to be a higher demand for greater transparency.

  3. Catherine Barber:

    What’s so striking to me is the differential burden for young black men. You don’t see these sort of differentials in health data very often, the scale is so huge for young black men – 90 per 100,000 for firearm homicides.

  4. Cary Woodruff:

    Previously, we could only really speculate, we could tell that a bone had broken and healed, but we had no idea of what caused the break. While that can certainly still be the case today, the more we approach these pathologies from a differential diagnosis perspective, and importantly, the more we work with medical professionals, the greater our identification accuracy is.

  5. Brooks Ritchey:

    If Greece goes, you win short term. If Greece doesn't, you win long-term because of the interest rates and monetary policy differential, U.S. versus ECB, you have two chances to win with short euro. You want to bet on two horses just in case one horse falls asleep.
