encounter_doc Posted August 29, 2006 Share Posted August 29, 2006 anyone out there interested in this sstuff? its actually a great read and the daily applications is phenomenal... Took 1 advanced physics course back in college, and I remember I was very much interested in quantum mechanics. The coolest principle in my opinion is the Heisenberg uncertainty principle, i.e. it's impossible to measure (with arbitrary precision) certain pairs of properties (e.g. position and momentum) of a single elementary particle at the same time. If you increase the precision in measuring a particle's position, the effect is it will decrease the precision in measuring the momentum; and vice-versa. In general, quantum mechanics changed the Newtonian view of the world that existed for almost 300 years - when you go down to the elementary particle level, Newton's laws of physics won't apply anymore. Now thats what I call a revolutionary idea! Quote Link to comment

Equus Posted September 19, 2006 Share Posted September 19, 2006 yep yep... i love the fact that macroscopic observable reality does not apply to the world of the very small... knda proves that fractal theory does not exist... unless we deduce that perception of reality is not reality at all... hehehehehehehe... ismple analogy, you get a car, running on gasoline and electricity... that much we know. lets say you make another car, at 1/2 inch in size, even if you microscopically make engine components through nano tech, the small car cannot run on gasoline and electricity... reason? the viscosity of gasoline is too dense for an automobile of that size to use... point being, rules and LAWS change when dealing with the very small... Heisenbergs uncertainty principle is cool... I also love schroedingers/wheelers cat thought experiment... it says that if you put a cat inside a closed box and with that cat in the box, you put a vial ful of cyanide and a radioactive isotope beside that... question being, is the cat dead or alive...? Answer? it is either and neither... it's both. until you observe it.. whats the point? the reality of whether or not the cat is dead or alive is solely dependent on the observer and not on an actual facet of reality... hehehehehehehehehehee.... doc, have you read the EPR paper? Quote Link to comment
encounter_doc Posted September 19, 2006 Share Posted September 19, 2006 hehehehehehehehehehee.... doc, have you read the EPR paper? Yes, the "cat" analogy by Schrodinger was very good ... I remember my professor used that as an example as well. I was never into "hard core" physics (which was really one of my academic frustrations), so I wasnt able to read the complete EPR (Einsteing-Podolsky-Rosen) paper. Quote Link to comment
Equus Posted September 19, 2006 Share Posted September 19, 2006 well the EPR paper was more into justification of reality in due respect to its locality. Stating that "an object/event/whatever is only real if you can observe it and upon its observation, your perception does not disturb its state of reality./" or something like that...

shadowspy Posted September 28, 2006 Share Posted September 28, 2006 Took up 1 subject in quantum mechanics in undergrad and 2 subjects in grad school. Interesting topic. Pero sometimes, the mathematics are hard to grasp. Took me a while to make sense out of those equations. Quote Link to comment

foxy_fujiko Posted October 24, 2006 Share Posted October 24, 2006 Order from chaos is a matter of dimensions & reflexivity. Tis how I deal with both the physical & social sciences.omg... same here.. I cant boast of taking up any advance physics subject back in school but I love Quantum Mechanics... reinforces the idea that change is constant even with existing laws... yay.. if you guys have any more ideas post it here... I want to learn more... im bumping the thread too... Quote Link to comment

Mobius Stripper Posted October 27, 2006 Share Posted October 27, 2006 (edited) Isn't it amazing how Einstein's Laws of the Expanding Universe conflict with the Randomness of Sub-Atomic Particles of Heisenberg's Principles & vice versa? No wonder they were at each other's necks. Anyone studying string theory here? Edited October 27, 2006 by Mobius Stripper Quote Link to comment
