Many parts of maths would probably come back if I ever made an attempt to refresh my memories, because it was more about doing than about memorizing. But all the fact-based subjects, from biology through physics to history, are mostly gone. The basic frameworks are there still, but none of the details.<\/p>\n<p>Languages have been truly useful. English, of course, and French, and even the smattering of German I learned in university.<\/p>\n<p>In a strong second place after languages comes basic geometry. Pythagoras&#8217; theorem is good for all kinds of everyday problems, from shaping the sleeve of a knit cardigan to estimating the length of steel flowerbed edging. And the relationship between the radius and the area of a circle comes in surprisingly handy for estimating the size of a pancake pan, and hence the right amount of batter. If the radius of the large pan is about 50% larger than that of the small pan, then the amount of batter will be 100% larger. 0.5 dl for the small pan, 0.7 for the medium, 1 whole dl for the largest one. I could of course reach the same result with trial and error, but that&#8217;s less fun.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sometimes the kids grumble over schoolwork and ask me whether I&#8217;ve ever needed to know the year when Gustav Vasa became king of Sweden, or some such thing.
