Radioactivity in quantum physics

Shouldn't quantum Zeno effect slow down the decay considerably in this case, compared to decays of single isolated atomes?

No, I just wanted to know how radioactivity is viewed theoretically in orthodox quantum physics. DrClaude's post #4 is very instructive...

Oh and another question, more mathematical: If I take the limit ##m_1\rightarrow 0## instead of ##\frac{m_1}{m_2}\rightarrow 0##, I get...

Okay. For consistency, let ##T_1=T_r## and ##T_2=T_b##. I'll assume no slack, which means ##a_1>g## (otherwise, both masses are free...

Ah, I see. I think I'm running into trouble here because of my assumption that if ##m_2\gg m_1##, then ##m_2## is "practically" free...

Okay, that makes my initial question trivial. I was way too focused on finding the forces first to realize that the acceleration can be...

I used the law of the lever on the wheel and axle and added this force to the gravitational force acting on ##m_1## (but I see now that...

But if the blue rope accelerates at ##g##, then the red one does so at ##\frac{d_1}{d_2}g##. And if my ##F_1## from #1 is correct and...

Hi. The following situation: The pulleys are fixed to the floor/ceiling and massless, as are the ropes, and there is no friction. At...
