Physics says plants never lose, and on Tea & Terps, Nik makes the case with three equations and then a fourth.
This clip pulls together Planck, Gibbs, and Nernst to explain how a plant manages energy at the molecular level. Planck's law tells you how much light energy arrives. Gibbs free energy tells you what work it can do. Nernst governs the electron-and-proton dance: separating charges now, recombining them later through metabolism. That's textbook physical chemistry.
Then Nik makes his move. Photons strike the chromophores in anthocyanin pigments, one of the plant's protective layers, and protective pigments, antioxidants, and chelating agents can help those pieces hold the most favorable positions possible even as NPK shifts around. Here's the metaphor that ties it together: the NPK model taught us to ask which pieces we can manipulate on the board, while these equations taught us to ask which pieces we can manipulate the board with.
The closer rests on a fourth equation, the one Nik thinks these physicists were really onto: electrical potential is directly related to useful work. Learn how to work with energy and, barring the extreme ends of the laws of physics, plants hold their ground. The way Nik puts it: they never lose.
Practical takeaway: before adding another round of NPK to a stalled plant, look at the energy side of the board: light reaching the leaf, minerals staying chelated and available, antioxidant capacity holding the position.
