Nature.is articles: Sólin

Aldrei má horfa í sólina!

Sólin er ekki aðeins björt heldur líka heit, enda er hún eldhnöttur. Má finna mun á hita þegar andlitinu er snúið að sól (með lokuð augu!) eða frá henni, verið í sólarljósi eða skugga?

Þennan hita má líka mæla, beint með hitamæli.

Eða óbeint; ísmolar settir í tvö glös. Annað glasið haft í sól, hitt í skugga. Í hvoru glasinu bráðna ísmolarnir fyrr?
