The other assumption is the corollary of the first; the biosphere has the same overall concentration of radiocarbon as the atmosphere due to equilibrium.
Radiocarbon’s entry into the global carbon cycle starts in the atmosphere where it is formed by the interaction of neutrons produced by cosmic rays with nitrogen atoms.
For a while I thought it could be an essay, but I couldn’t wrap my mind around it.
It occurred to me that maybe everything I thought I understood about love was wrong, and that it was all connected to these narratives of love that I had invested in, including my parents’ own love story.
Mixing and exchanges happen between the atmosphere and the biosphere until such time that equilibrium is established.
Radiocarbon dating rests heavily on this assumption such that other sources of carbon 14 had, at first, not been considered nor accounted for.
Her piece, which referenced psychologist Arthur Aron’s “36 Questions That Lead to Love,” went viral, and an equally popular TED Talk soon followed.
Last month, she published her first book, about—you guessed it—love.
This 1,344 square foot house sits on a 6.58 acre lot and features 2 bedrooms and 1 bathroom.
This property was built in 1950 and last sold on May 31, 2017 for 5,000.
The carbon 14 produced reacts with oxygen atoms in the atmosphere to form carbon dioxide.
