多様性の比率 (Essay) Ratio of Diversity, 2:8 Rule?
研究室にいながら、異なる分野、異なる文化背景などの異質を巻き込んだ多様性のある環境に身を置くことで、不確実性を経験することができます。By being in a diverse environment involving different fields, different cultural backgrounds, etc. while in the lab, students can experience uncertainty.

Essay: Interdisciplinary Research for the “Next” Education
Global challenges are always complex, so placing an excessive value on a competition will lead the world in the wrong direction. For the long term good, the winner will be meaningless. Understanding and caring about each other’s history is the key to collaborating with other countries.
学際的なアプローチの重要性(Essay) Pentingnya pendekatan interdisipliner.
Tantangan global itu selalu kompleks, sehingga penempatan nilai yang berlebihan pada suatu persaingan akan membuat dunia ini menuju ke arah yang tidak tepat. Untuk kebaikan jangka panjang, siapa pemenangnya akan menjadi tidak berarti. グローバルな課題は常に複雑であるため、競争に過度の価値を置くと、世界は間違った方向に導かれます。 長期的な利益のための勝者は無意味になります。
