.. an orchard owner has maintained records that show that if 25 appl trees are planted in one acre then each tree yields an aveerage of 500 apples. The yield decreases by 10 apples per tree for each additional tree that is planted. How many trees should be planted for max total yield? The...

This paper does a lot of testing of different kinds, and concludes that the string theorists assertion that the graviton reproduces the physics of GR in flat spacetime is a myth.

Would a massless spin 2 boson traveling at light speed collide with a fermion to yield particle-antiparticle pairs (if the spin 2 was a graviton the particles would have to have a very small mass so far undetected by science)? Could this spin 2 boson be electromagnetic in nature? Could a...

Just a few questions I have and I cannot seem to find any good explanations in the book: 1) How do you calculate mass yield of a solution? 2) How do you calculate the number of moles used in a titration? Any help is greatly appreciated.

fire.biol.wwu.edu/trent/alles/Origin_of_Elements.pdf In this source Alles gives a detailed description of the mechanism underlying Type Ia supernovas----so that one sees why they always release about the same amount of energy and can be used as standard candles for measuring distance. But he...
