Fascinating and apparently replicating results for a century! I agree and to understand the experiment's intractability, I need to know more about the conditions under which the results were measured without "observation". Were electrons, et al, fired at a wall with slits in a room devoid of observers, utilizing some kind of delayed turn-on switch? And the results reviewed after the fact? How can you possibly control the experiment to the extent that the only difference leading to this "weird" result is the presence of an observer? Is the equipment used in measuring the same as when observing and measuring? (Has anyone observed from an adjacent room through a window?) My scientific background is non-extant and I'm striving to understand what an objective experiment in this case would look like.
