Hmm. I think there is a slightly misleading statement in the song. Wave-particle duality is not related to the wavefunction, which is a complete, probabilistc mathematical description of a system. De Broglie waves and particles actually (co-)exist, but the particle can be forced to become either depending on how we observe it.
Why is Carl Sagan singing in the chorus? He's a cosmologist as far as I know and has no connection to QM. It might be because he's a popular science figure.
Energy sources without the need for fuel or energy input exist ,But the Oil companies want these technologies unknown to the masses,Get the blueprints for a real Magnet motor free enegy machine at LT-MAGNET-MOTORdotCOM ,Big change is comming soon!
Haha! Most of QM requires a good understanding of partial differential equations and linear algebra. Relativity requires tensors. So really, its a question of which upper-level mathematics you're more comfortable with. For me, it was the former. Some people probably think the latter is easier. Although special relativity is certainly the winner since it only needs algebra.
@nageljr The math complexity is probably similar, but the concept of a curved space-time is far simpler than physical states represented by elements of a Hilbert space and observables by self-adjoint operators... not to mention the paradoxes of every interpretation fo QM I have heard of (Copenhagen, Many-Worlds...)
@tombombadil10000 I like to think that QFT is bigger too! quantum has absorbed Special relativity and people have been trying to include general relativity as well. But you don't have too many relativists doing quantum theory.
this is bullshit. of you point a laser pointer to a needel edge you still see outcome from a slit experiment, but this time without the slit. ho can Q-physics explain that?
@maydayfire So what your saying is that under completely different conditions, because the outcome is similar, quantum mechanics must be wrong? What does a needlepoint have to do with the slit experiment?
Nice video, but what does diffraction of *light* by a slit have to do with quantum mechanics (being quite a nice home-makeable proof for wave nature of light though)?
The demonstration is assuming you already believe that light consists of photons, and is not really a continuous wave. The thing we really wanted to show is that a stream of discrete photons distributed in a sinc-squared pattern (the little red-dot animation) produces a nearly identical pattern to the one you see with the laser interference. So really, I guess we should call it a "correspondence" demo, but whatever. It still looks cool, right? :)
if light is made of particles, as was once "proven", classically it shouldn't interfere or diffract. Since is does, is must also be a "wave" - hence the wave-particle duality.
Nearly every modern technology owes its existence to quantum mechanics. Computers, CDs, DVDs, solar cells, MRI scanners, spectroscopy, pharmaceuticals, fiber optics, lasers, Teflon, LEDs, digital cameras, everything. They all would fail to function if quantum theory were not true and correct.
Compare: All 18e century equipment has been made according to the newtonian mechanics is Newton always right then?No, Newton can't describe the quantumphenomena or the mechanics at very high speeds
It's just that we haven't found a flaw in the quantumtheorie. But a lack of experimental prove that a theory is not true, does NOT prove that the theory is right!
