what is it that makes materials strong ? density ? melted ? chemistry reactions ? strong nuclear force ? all of that ? regards garfield1729

hi all why do many things in physics move in waves ? in fact , if I am not mistaken , everything apart from mass moves in waves : electromagnetism ( and light ) , heat ( not ? ) (do phonons move in waves or lines ? ) , radioactiv rays , weak nuclear force , gravitons (?) and many "...

sorry if i annoye you. im sorry , I am no expert in physics , don't intend to be a crakpot. im not here to promote or believe in perpetuum mobile. in fact i don't believe in perpetuum mobile or free energy. but does it make sense to say " garfield is wrong ; because if he were right ...

yes a thermos is a nice example of something that keeps things hot when hot and cool when cool. so you claim no thermos of " exotic material " can be made to only keep cool ? what about those boxes you put ice into keep the food cold ? they don't heat up much when the envirement out of...

why don't you guys believe me ? isolation materials are used all the time. what about greenhouses , isolation material to keep out the cold in buildings , or to keep out the heat in warm countries. so you are claming all materials either both conduct cold and heat or neither ?

hi everybody, how does isolation work ? some things don't conduct heat , whereas other don't conduct cold. what gives these properties ? and in what proportion ? im pretty sure mass density of the objects is sometimes related , but there must be more factors to it since light...
