Reed students celebrate “Nitrogen Day” every year because it is arguably one of the coolest elements on the periodic table.

And even though the air we breathe is mostly nitrogen (nitrogen gas makes up 78% of the atmosphere), our bodies can’t process it in that form. Instead, we need bacteria and plants to “fix” atmosp...
