TO THE 120<sup>th</sup> ANNIVERSARY OF A.L. CHIZHEVSKY’S BIRTH
Alexander Leonidovich Chizhevsky (1897-1964) is the founder of heliobiology. This paper is presented as a scientific essay and is dedicated to the memory of Chizhevsky. We briefly discuss an unusual aspect of heliobiology. It is closely related to the question whether living organisms are macroscopic quantum objects. There is no scientifically grounded answer to the question, but many scientists are inclined to give a positive answer based on indirect evidence. The project of biophysical experiment using an original device for excitation of the field of vector potential is described in the hope that in future such types of experiments will make it possible to clarify the question.
