Research more or less in, on, or about dogs and/or calculus
by Otto Didact, Improbable Research staff
The College Mathematics Journal published a series of studies by humans who were chewing at the question of whether and how dogs do calculus. Here are some significant items from that series.
Do
“Do Dogs Know Calculus?” Timothy J. Pennings, The College Mathematics Journal, vol. 34, no. 3, May 2003, pp. 178-182.
Don’t
“Dogs Don’t Need Calculus,” Michael Bolt and Daniel C. Isaksen, The College Mathematics Journal, vol. 41, no. 1, January 2010, pp. 10-16. The authors implore:
Many optimization problems can be solved without resorting to calculus. This article develops a newvariational method for optimization that relies on inequalities. The method is illustrated by four examples, the last of which provides a completely algebraic solution to the problem of minimizing the time it takes a dog to retrieve a thrown ball, demonstrating that dogs don’t need calculus.

Variations

Bifurcations
“Do Dogs Know Bifurcations?,” Roland Minton and Timothy J. Pennings, The College Mathematics Journal, vol. 38, no. 5, November 2007, pp. 356-361
Trammel?

Rates?

The betamax died out in the mid 80's do to the same reasons MiniDisc, and 7" audio disks died. Sony kept the tech proprietary. The tapes, discs, whatever material had to be bought along with the machines, from Sony ALONE. At Sony's prices. Which are, even today, still at the top of the bar for consumer electronics. The VHS was licensed freely and had very strong competition driving down costs on both the machines and consumables along with raising competition for features on the machines. But Sony tech stagnated and did not continue to keep up with feature upgrades since they were not making the sales.
This simply a case of keeping too tight a hold and not having a strong enough brand to carry the price tag. Apple runs this risk as well. And, as competition increases giving other devices and OSes equal footing, Apple continues to loose market share. JUST LIKE Sony. It's simply a case of market econ.
