and today we have a wonderful guest maria kalinina, doctor of chemistry, professor of the russian academy of sciences, leading researcher at the frunkin institute of physical chemistry and electrochemistryabsolutely correct. 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 say i, of course, yes. well , i, probably, like everyone else, like most of the housewives in our country, first of all cook. borsch cabbage soup in a hodgepodge, well, occasionally 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. it seems to me that it is worth giving a definition of what is caloid chemistry, columnar chemistry studies surface phenomena and the behavior of dispersed systems. so the crushed one was already frightened immediately for soup. you look with some horror. well, we grind it into ingredients, which we take for him any voluminous object that the listener is
