*I am just a novice who has done one or two undergrad courses in Physics, so forgive me if my questions seem to be silly.* According to Heisenberg 's principle , the exact location of an electron can't be ascertained as whatever radiation we use displaces it. Furthermore , there is an irony that for smaller wavelengths of the radiation used , the energy of the radiation is high , so this causes greater displacements of the electron . So we can only speak in terms of probabilities of the electron . I would like to know , what is the scientific explanation that this is the only way one can detect particles , viz using some sort of radiation ? We have got 5 senses viz Eye , touch , nose , ear , taste , so any input that we get through these is definitely depended on some sort of wave or the other . But how does this rule out some other being on some distant planet not being able to detect particles using some other means ? Even if it is theoretically impossible for humans to do so , how does that rule out the real picture ? I am particularly uncomfortable with the statement :-GOD DOES PLAY DICE . Now I am neither implying the existence nor non-existence of God . But , all I am saying is suppose there is a God outside the bounds of our universe , and he/she/it has a means of detecting particles without making use of radiations , won't he/she/it be able to speak of electrons entirely in terms of particles ? Shouldn't we be saying:- GOD MAY OR MAY NOT BE PLAYING DICE , BUT FOR US , HE/SHE/IT SEEMS TO BE PLAYING DICE. I would be glad if someone told me about theories or websites where such issues are discussed . Also , I would like to know some good books or websites where the basics of the maths behind quantum mechanics are given , so that I can begin getting to know this amazing branch of science.
