Hello

Can someone help me with this sentence: "I'm going from atoms to quarks
there is a change of scale by a factor of at least 10 million. It is impressive than quantum mechanics can take that in its stride. The problems of interpretation cluster around two issues: the nature of reality and the nature of measurement."

I don't understand that sentence at all and there is no really a context with it because it comes from my linguistic books. The sentence is an example of some grammatical English features.

Thanks for your help
Je passe des atomes au quarks, et le changement d'échelle est d'au moins 10 million. C'est impressionnant de voir que la mécanique quantique peut aller de l'un à l'autre (littéralement "peut faire ça dans sa marche"). Les problèmes d'interprétation se regroupent autour de deux choses : la nature de la réalité et la nature des mesures.
Is the problem that you don't know what a quark is? An atom (nucleus and surrounding electrons) is about 10^(-10) meters (0.1 nanometer, nm). A nucleus is about 10^(-16) meters (0.1 femtometer, fm). A quark is a subatomic particle that is not seen isolated; protons and neutrons are made up of three quarks.
oh ok. You're right. I did not understand the meaning of "quark" but I see what it means now. Thank you very much
