Please check the youtube video on sizes from Planck length to whole universe . My question is at 1:34 instance. What is the range of the size for the quantum effects to happen at noticeable state i.e. as per the sizes shown in the video from which point upto which point we can expect the quantum nature of particles should occur? At 1:34 the sizes of UV light, virus, transistor gate are shown. Can I assume that transistor gate, virus etc. may face the quantum effects i.e. uncertainty, wave-particle duality etc.
