The study of science implies not only the presence of talent, but first of all, it requires aspiration and a strong desire. Without these characteristics, it will be complicated, and not many will be able to engage in this field. However, there are people with disabilities who could prevent them from studying various sciences, but they have only proved that everything is possible. One such example was Professor Stephen Hawking, who investigated the basic laws governing the universe. Despite the illness that deprived him of movement, he devoted his whole life to developing an equation to combine relativity theory and quantum physics, which was called the theory of everything.
Stephen Hawking was a pioneer in the study of the origin and structure of the universe. He studied the Big Bang and black holes and revolutionized this field. Therefore, being the most significant theoretical physicist in the history of humankind, Hawking had a massive obstacle in his path (Pinochet, 2019). The man had amyotrophic lateral sclerosis (ALS), which leads to impaired function of motor neurons in the brain and prevents the transmission of messages to the muscles of the body (Gopakumar & Wadia, 2018). As this circumstance ultimately deprived the scientist of doing his job, and a practical solution was found.
A specialized chair equipped with the latest technologies was created for him. Hence, Hawking used a thumb switch and a flashing switch to control the computer. For communication and continuation of work and various performances, the scientist used the movements of the muscles of the cheeks and eyelids to activate the infrared switch. With it, he chose characters to compose speeches, view information, speak through a voice synthesizer, and, most importantly, continue his valuable activities.
