and today we have a wonderful guest , maria kalinina, doctor of chemistry , professor of the russian academy of sciences, leading researcher at the frukkin institute of physical chemistry and electrochemistrye out quite right. and today we will talk on the one hand about very difficult chemistry. and about very simple things, for example, about the court. let's try to tie them together. let's start with the soup, well, the forces have at least ever eaten the court, and sometimes cooked the court. you speak. of course i do. well, i, probably, like everyone else, like most of the housewives in our country, first of all cook, borscht cabbage soup in a hodgepodge. uh, well, occasionally a pickle. well, where to start more you can remove from the broth quite right. and what is the broth in terms of colloidal chemistry? bouillon? let's do it anyway. i think it's worth giving definition of what is caloid chemistry, column chemistry studies surface phenomena and the behavior of dispersed disperse systems. so the crushed one was already frightened immediately for soup. you look with some horror. well, we grind into ingredients that we take for him any volumetric object that the listener is looking
