Nankali's Masticatory Force Systematization force of the masticatory system and discovered the differences in the produced force, which was approximately doubled. The periodontal system controls automatically the measure of mastication force in this process and the jaw elevator muscles develop the main forces used in mastication. Dr. Weber worked out that 1 cm cross section surface area of any masticatory muscle can produce approximately 10 kg force. The following average surfaces were found: temporalis - 8 cm, masseter - 7.5 cm, and medial pterygoid - 4 cm which makes a total of 19.5cm. However, this force in some people is measured up to 3900N
What the Tortoise Said to Achilles to suggest that the moral of the dialogue is a particular case of a general lesson, to the effect that the proper "application" of rules governing a form of human activity cannot itself be summed up with a set of "further" rules, and so that "a form of human activity can never be summed up in a set of explicit precepts" (p. 53). Carroll's dialogue is apparently the first description of an obstacle to conventionalism about logical truth, later reworked in more sober philosophical terms by W.V.O. Quine.
