This website was created in memory of Kostyantyn Gusliyenko: a genius, extraordinary scientist, who was passionate and devoted to his work, that was his life's purpose. His day started and finished from writing formulas in his notepads. On this website we have uploaded the copies of his notebooks, more than 5 000 pages. The notebooks are in reverse chronological order from November 2025 to May 1985.

Kostyantyn, I wanted to keep and save all your work that you have done with such love and desire to advance science in this world for the better. So, that young or new scientists can learn from you. By doing so I am expressing my admiration of your devotion and love to science. I am thanking you for this event-filled, active and bright scientific road that we have passed together hand in hand during 45 years of our life.

Kosten`ka wherever you are through time and space, in other worlds, in other dimensions, in other galaxies in our universe I am sending you my LOVE and GRATITUDE for everything.
