"Between air and earth there is a tree not only graphic but literally." Where does a plant get it´s mass from? "From the soil." one intuitively could answer. "Soil and water maybe." Jan Baptist van Helmont came to be in 1580 and left in 1644. He asked himself the same question and made an experiment. He grew a willow tree and measured (soil, water and weight) five years long. 74kg was the weight of the tree, but the soil remained nearly the same. So water it is, meant Jan. Today we say that it comes from air, most of it. A plant takes the carbon dioxide from the air and uses sunlight to chop out the oxygen. Then it stirs the carbon together with water, which also comes from the air in the form of rain. Just some minerals are added from earth. That is it! A tree is growing and when fallen, turns further to earth, a piece of paper or a chair. Or a warm fire in a cold winter night, which is again, released sun energy, catched long before over an amount of time, by a tree. It keeps on spinning leaving me giddy. Amazing! "Straight up, that is the way to be you could hear from every tree except at your very end earth calls you, my dearest friend."
