Now, I tried a video describing Planck's constant, but the video started quoting IMPOSSIBLY small things. Whew!! It bit the dust for me. Anyways, there is plenty of Planck's constant info on the internet and YouTube. I don't LIKE numbers used in Physics. It burns like fire to IMAGINE such entities. So I stay away from the numbers game used by Physicists.
That's just my defect. I live in the Middle World of 5-sensory things. That's IT for me.
