星屑を探して | Jon Larsen | TEDxFredrikstad

小さな粒子は屋根や窓辺、市街地の路上などに絶えず降り積もっています。このTEDxFredrikstadの講演では、ノルウェーのジャズミュージシャン、作曲家、ビジュアルアーティストであり市民科学者でもあるJon Larsenが、身近な塵への持続的な好奇心が音楽から顕微鏡へと彼を導いた経緯を語ります。Stardustプロジェクトが、微隕石と人為的な粒子を見分ける方法をどのように開発したかも説明されます。講演はまた、日常的なものへの注意深い観察が予想外の発見につながりうることにも触れています。

• ジャズから市民科学へ

Stardust is falling around us all the time. On rooftops, windowsills and city streets. Jon Larsen tells how an obsessive curiosity about tiny particles led from jazz clubs to microscopes, scientific verification and a new way of finding micrometeorites in urban environments. His story is not only about cosmic dust. It is about attention: how a willingness to look closely at the ordinary can open an unexpected path to discovery, and how science can begin with a simple question that nobody thought worth asking. Jon Larsen is a Norwegian jazz musician, composer, visual artist and citizen scientist. After decades in music, including as a founding figure in Hot Club de Norvège, his curiosity shifted toward tiny particles hidden in everyday dust. Through the Stardust Project he developed methods for distinguishing micrometeorites from human-made particles, contributing to research that helped change how scientists think about collecting modern cosmic dust in populated areas. His journey is a reminder that expertise can begin with sustained curiosity and that discovery sometimes starts by looking closely at what everyone else ignores.
