monkeyborg, Can’t say more without revealing where I work, but this week I read about a jaw-dropping bit of experimentation — by an undergrad! — which may allow us soon to visualize what exactly is happening with quantum wave-particle duality. Like in an intuitive, “oh that’s what that means” kind of way, not a “don’t try to understand it, just do the math” kind of way. Very exciting for pop science nerds like yours truly.
