Agar was first introduced into the laboratory in 1881. Since then, microbiologists have depended on agar to create strong jellies. When microorganisms are streaked or plated onto this jellied surface and incubated, individual cells multiply into distinct colonies that scientists can easily observe, select, and propagate for further experiments. Many of the most important findings in biological research of the last 150 years or so — including the discovery of the CRISPR/Cas9 gene-editing tool — have been enabled by agar.4 Agarose, a derivative of agar, is also essential in molecular biology techniques like gel electrophoresis, where its porous gel matrix separates DNA fragments by size, enabling researchers to analyze and isolate specific genetic sequences.

在流亡的日子里，家人的消息是塔可夫斯基最大的慰藉，也最容易触动他心底的柔软。友人奥列格・扬科夫斯基带来一个包裹，里面是他的所有剧本，还有儿子佳普斯、亲友安娜・谢苗诺夫娜和达库斯的照片。他在日记中写道：“让人既感动又悲伤，我很想哭。”一张照片便能轻易击溃这位硬汉导演的心理防线。收到儿子寄来的一封信和一幅画，画里的布兰卡乔城堡逼真动人，塔可夫斯基写道：“关于安德留什卡，我现在不敢提笔记录，甚至连想都不敢想起……”
