How Making Things Bigger or Smaller Changes Behavior
19 pgs,77Q/solnScale models involve scaling dimensions up or down and this changes properties like weight, surface area, height. These in turn change heat energy, temperature change, suit costs, strength to weight which changes the ability to move even. Ants have a problem with water attached to their bodies. Making something taller means that eventually it won't be able to hold up its own weight. Why are tiny people impossible or why couldn't mon
