Question: Title: More futility of utility Review: Amazing for what it misses. Sato could have solved the problem advertised by Mirowski, but merely worked all around it without seeing it. Discusses the question whether it is legitimate to assume 'price as gradient of utility' from the standpoint of Frobenius' theorem (hitting a nut with a sledgehammer), but fails to apply similar horsepower to the Hamilton-Jacobi equation (discussed in the last pages). Therefore misses the main point: in optimization problems (Hamiltonian dynamics), price as a function of demand or supply ('price equals gradient of utility'), and utility itself, do not exist unless the Hamiltonian dynamical system is Liouville integrable (see my paper "The Futility of Utility"). Is the review positive or negative?
Answer: Negative

Question: Title: A ++++ cordless Review: Ive had this phone for several years now and it is the best phone I've ever seen. It is clear on both handset and base unit, the answer machine is clear to both the caller and listing to message on other end. I can go for 3 1/2 to 4 weeks on a single charge before I need to put handset back in charging cradle. Answer machine has toll ctr. which is also nice. Is the review positive or negative?
Answer: Positive

Question: Title: great for pets and kids! Review: Originally found these on clearance at a farm and ranch store. Thought they were a great concept. knot the bag and make it as big or as small as you need. Used them for doggie doo, dirty diapers, wet swimsuits, etc. leave them in the diaper bag for what ever comes up. Great product, and the light scent helps with the stinky odors too!
