"Thus quantum mechanics is a statistical theory. It can make definite predictions about ensembles of identical systems, but it can generally tell us nothing definite about an individual system. Where it differs from other statistical theories, such as statistical mechanics, weather forecasting...
I have to clear something here that
in the second scenario when talking about radiating, I am supposing that the temperature of two objects are equal.
actually i remember some sentence that i have heared in school "Black objects both absorb and radiate heat more (stronger) that white objects "...
black material is black becuase it absorbs more energy and reflect less.
what i think is :
the amount of radiation depends on temperature and material.
the amount of absorption depends on the amount of radiation the object is exposed to and the material
if we have two objects white(W) and...
excuse me if this is too basic question. why is it that black materials BOTH "absorb" and "radiate" more heat ( energy ) and white materials do it less. i mean is there a rule that any material absorbs and radiate heat in the same amount and can't absorb more (like black materials) and...
im happy that despite my seemingly general question the conversation went thr way i expected. actually this was a confusion for me since one of my friends was trying to tell me about quantum physics (my major is computer science and i don't have any education in the field of quantum physics but...
Thank all of you for reply. I am new here and i didn't know where to post my question. i wanted to what do people exactly mean when they use the word RANDOM in physics.
maybe this is too basic question but it is not so clear for me. when we refer to a random experiment, can a phenomenon be absolutely random by itself or its all about our uncertainty about the outcome that we call it random?
