I propose English speakers to replace for quarantine & social distance issues “Let us keep in touch” by “Let us keep in distance”. More polite but technical variants may be “Let us keep in nonlocal touch”, “Let us keep in noncausal distance”, “Let us keep in uncorrelated touch”.
I constantly tell my students & researchers: never calculate anything if you do not know the answer. You only know the answer beforehand if the problem is perfectly well posed. Why to waste time & efforts calculating then? This philosophy is central to my way of doing research.
