Nikola Tesla (1856-1943) was an electrical and mechanical engineer. He was born in Serbia but lived in the US beginning in 1884. Tesla described the phenomenon of the rotating magnetic field, and developed polyphase machines and allocation schemes of polyphase currents. He pioneered high-frequency engineering (generators, transformers, etc.) and also researched the possibility of wireless energy transfer to electronic power devices. Tesla’s contemporaries called him the “Lord of lightning.”

Tesla’s perception had its own peculiarities. Any image he had ever come across was presented in many tiny details in his mind as soon as he heard something that he associated with the visual image in question. Many believe that Tesla had an explicit synesthesia – a perception phenomenon which is expressed by means of a sense other than the one being stimulated. Before beginning the creation of a new invention Tesla could imagine it in details clearly.

Andrei Tupolev (1888 – 1972) was a Russian aircraft designer. Under the supervision of Tupolev over 100 types of aircraft were designed including the first intercontinental turboprop passenger jet Tu-114. Seventy-eight world records were set using his planes.

Tupolev was in a state of “inner observation” pretty much most of the time. He “observed” the problem “inside himself.” Tupolev said that incorrect decisions affected him physically: “You realize and feel that it won’t work, it feels wrong, sometimes it feels physically disgusting.” He could gently shake a plane and reveal the structural weaknesses that would be damaged first. He had an ability to “get the feel” of the contraption and feel the “behavior” of the air space from within.

A professional painter worked in Tupolev’s design department. He worked on detection and fixing the future plane image.

Pierre-Auguste Renoir (1841 -1919) was a French painter, graphic artist, sculptor, and one of the leading representatives of the Impressionist style. During his career, which lasted around 60 years, he created 6, 000 paintings meaning he painted, on average, two pictures each week.

Osho, an Indian mystic, guru, and spiritual teacher, said the following about Renoir, “Artists painted a woman’s body the way it looked like in their eyes. Renoir painted it the way it felt in his hands.” Renoir’s perception presented in his paintings is notable for its warmth, closeness, and joy. He was recognized among his contemporaries mostly thanks to his portrait-painting skills. Renoir didn’t flatter his models; he looked at them as happily and joyfully as he looked at everything around him, and that’s why people appeared happy and beautiful in his works.

Salvador Dali (1904 - 1989) was a Spanish painter, graphic artist, sculptor, director, and a writer. He was one of the most prominent surrealist painters and one of the greatest eccentrics of the 20th century. Dali was the master of the outrageous, author of shocking revelations about his life and ironic arguments about people and objects. They say he was driven by the desire to be different from his contemporaries, yet at the same time he wanted to be the leader with his own singularly correct points of view.

Contradiction was his perception criterion. He was fond of seeing, showing, and combining incompatible things. Perceptible and clear images were full of both uncertainty and ambiguity in his paintings. “Realistic in unrealistic” was the basic idea of his creativity. With an extraordinary imagination Dali combined diverse objects and caused a clash between them in unnatural situations.
