Homeopathy

Though Korsakov was not formally trained as a doctor, he was interested in medicine, possibly because of the difficulty in getting medical care in the rural area where he lived. According to his journals he treated several thousand patients, at first using
conventional medicine Medicine is the science and Praxis (process), practice of caring for a patient, managing the diagnosis, prognosis, Preventive medicine, prevention, therapy, treatment, Palliative care, palliation of their injury or disease, and Health promotion ...
, but in 1829 switching to homeopathy at the urging of his relatives. Korsakov is noted in homeopathic circles as the originator of the Korsakovian method of dilution, which differed from the Hahnemannian dilutions used by (and named for) homeopathy's founder in that it used a single container for a series of dilutions rather than a new container for each. Korsakov also used dilutions higher than those previously used (30C and higher). Dilutions made using his method are commonly designated with the letter "K", e.g. 15K.


Inventions

While working in the statistics department of the Police Ministry, Korsakov became intrigued with the possibility of using machinery to "enhance natural intelligence". To this end, he devised several devices which he called "machines for the comparison of ideas".Intellectual machines
These included the "linear homeoscope with movable parts", the "linear homeoscope without movable parts", the "flat homeoscope", the "ideoscope", and the "simple comparator". The purpose of the devices was primarily to facilitate the search for information, stored in the form of punched cards or similar media (for example, wooden boards with perforations). Korsakov announced his new method in September 1832, and rather than seeking patents offered the machines for public use. The

, when a revival of historical interest resulted in the publication (in 1961) of several documents from the academy's archives relating to Korsakov's machines and the uncovering of a book about them written by Korsakov himself.
