Physical science and chemistry have reached a degree of development that should allow
them to start describing plants with more physical models than ever before. All
knowledge on genetics grants us now at least an insight into how mass and energy
transfer is regulated. Computational and storage capacity make it possible these days to
acquire data and calculate biological models and results complex enough to make sense in
the biological way. It may sound strange, but building the first atomic bomb and flying to
the moon was possible with a much lower computational capacity than just taking daily 4
images of 1,000 plants, putting them in a database and analysing their watering needs on
account of hanging leaves. As these capacities are now available, biologists should
develop concepts and apply them, learning as much as possible from the methods and
experience of the physicists to get a better understanding themselves: Better
understanding is the first step to better engineering.
