Paracelsus, a sixteenth-century alchemist and healer, adopted as his slogan: The patients are your textbook, the sickbed is your study. Is this view consistent with using the scientific method?
Why do we use an objects mass, rather than its weight, to indicate the amount of matter it contains?
Calculate the average density of a single Al-27 atom by assuming that it is a sphere with a radius of 0.143 nm. The masses of a proton, electron, and neutron are 1.67261024g,9.10941028g, and 1.67491024g, respectively. The volume of a sphere is 4r3/3, where r is its radius. Express the answer in grams per cubic centimeter. The density of aluminum is found experimentally to be 2.70 g/cm3. What does that suggest about the packing of aluminum atoms in the metal?
Scientific models do not describe reality. They are simplifications aid therefore incorrect at some level. So why are models useful?
