ジュールたち

Ｇ４

学歴なし、家業廃業、妻子死去、ジュール家没落。財が底をついても就職は眼中になく、明るくボン・ジュール、実験一筋の人生 / 死別の多い前半生。姉と父、妻を亡くし再婚は最初から悲惨極め、娘もうけて離別、翌年に母と死別。辛さに耐えて後半生に花を咲かすＡ / 豊かな才能、海を愛するＫ、海底ケーブル敷設に貢献 / 光学の父。外角定理（三角形の内角２つの和は隣り合わない外角と等しい）を通して彼の才能に触れる

Overcoming the difficulties and living brightly / He didn’t find a job despite lack of funds. He lived his life as an experimenter. / His sister and father died one after another. He didn’t motivate anything. His wife died of cancer. Remarriage disastrous from the very beginning
