Hi, I'm currently writting an article for people my age (15-18) about Quantum Physics, it's complexity, it's vast uncertainty and it's applications. However, being only young and just halfway through John Gribbin's 'In Search of Schrodinger's Cat', there are several points I would like to raise, but am unnable to explain. I am aware that this may belong in a homeowrk help thread, but I thought I would find the most passionnate and most qualified here. Simple answers please, this is only a simple article! Thanks in advance, PipBoy Q: In what way does a particle exhibit both wave like and particle like behaviour? What makes it like a wave, what makes it like a particle? Q: Does Quantum Theory agree with Relativity, and what is the definition of Relativity Theory? These as a start, thanks.
