Question 1: What is it that Hawking can talk but can't? How does Hawking talk to the outside world, give speeches and be interviewed by the media? "He relies on computer technology to communicate with the world." Professor Qiu Chengtong, a famous mathematician and a good friend of Hawking, said: Hawking has only three fingers to move. He used his fingers to operate the computer speech synthesizer to express his ideas. Every time he gives a speech, he will meditate for a while, then start his remote control, press one of the keys, and some English words will appear on the computer screen fixed in the wheelchair. At this moment, Hawking's eyes are particularly magical. His thumb keeps pressing, words become phrases, and phrases become sentences. When the thumb is pressed again, the sound comes from the speaker. What you hear is typical American English, with clear voice and cadence.

Technology has changed Hawking's life. After Hawking lost all speech functions, he communicated with people through eye contact for a while: he faced a spelling board and made people point to English letters. When he pointed to the letter he wanted, he raised his eyebrows and finally spelled the word. But this kind of communication is very difficult, let alone writing scientific papers. A Californian named Watt? Waldo's computer experts helped Hawking out of the predicament. He sent Hawking a computer program called Equalizer, which he wrote himself, so that Hawking could choose words from the screen. As long as he presses the switch in his hand, the words will be sent to the language synthesizer for pronunciation. Later, David, who oversees communications companies in Cambridge? Mei Sen improved a very small personal computer and speech synthesizer, which was installed in Hawking's wheelchair, greatly speeding up Hawking's "speaking" speed. He can create 15 words per minute, and he can speak and print out words.

Question 2: Why can't Stephen Hawking talk? Stephen Hawking can't pronounce because he has muscular dystrophy lateral sclerosis.

Question 3: Stephen Hawking can't write or speak, so how did he write A Brief History of Time? ... Steven had a tracheotomy for pneumonia on 1985, and completely lost the function of speaking. Speech and question-and-answer can only be done by a speech synthesizer.

So he can't speak, but the action of Adam's apple can be produced by a speech synthesizer. He spoke sentence by sentence and was written by his assistant.

Question 4: Mr Hawking can't speak, but he can still make a speech. How is it achieved? Of course he learned sign language!

Sorry, I was just kidding.

In fact, there is a vibration sensor next to his glasses. When the corner of his left eye moved down, 26 letters appeared on the display screen in front of him, and each screen was divided into 6 letters. When he sees the letter he wants to say, when his right eye moves the screen, all the words at the beginning of the letter will appear. When he sees the word he wants to say, he moves his right corner of his eye again and turns what he wants to say into sound.

According to media reports, Hawking only speaks 5-6 words per minute.

Question 5: How did Hawking give birth to a grandmother who was paralyzed and even needed someone to take care of her when talking and eating?

The closest person in my family is my grandmother, and I spent my whole childhood under her care. My grandfather died early, and my grandmother loved me the most among the older generation.

I remember when I was in primary school, my parents didn't have time to take care of me because of their busy work, so I would go to my grandmother's house for lunch alone every day after school at noon. Grandma's cooking is delicious. Every time I eat all the dishes on the table, grandma is very happy to see me so famous, so I have had lunch at her house for six years. Every time I get off the table after dinner, my grandmother will come over and ask me, "Are you full?" No matter how much I ate at the dinner table just now, she is always worried that I am not full, so she always asks after dinner.

After dinner, I usually watch TV for a while and then do my homework. After finishing my homework, my grandmother will ask me again, "Are you hungry?" ? Do you want something to eat? "At this time, when I said I was hungry, my grandmother would immediately run into the kitchen to get busy, and soon a dish was served in front of me. If I say I'm not hungry, my grandmother will try her best to persuade me to eat some fruit. If I insist on not eating, she will put an apple in my bag before I go to school, in case I am hungry in the afternoon and have nothing to eat.

My grandmother devoted herself to the whole family all her life. She has little education and a little backward in thinking, but she has been quietly raising for generations. She can't be ordinary in this world, nor can she be ordinary, but without her busyness in our big family, our life can't be so orderly. Sometimes I talk back to her, sometimes I lose my temper in front of her, but every time I regret it afterwards, I see her kindness to me.

I have always remembered my grandmother's kindness to me since I was a child. I hope I can repay her later. These two words of my grandmother have always been treasured in my mind and become the warmest memories in my childhood memory.

Dream catcher-Hawking

The universe is mysterious to people. Because it is so vast, no matter how hard people try to explore and reason, it is just groundless speculation. Since ancient times, one scientist after another has devoted his life to this great proposition. Among scientists, the brightest star stands out. He is: Steven? William? Hawking.

Hawking was born in Oxford, England on 1920. At the age of 17, Hawking entered the University College of Oxford University to study natural science. It took him very little time to get a first-class honorary degree, and then he transferred to Cambridge University to study cosmology. Hawking's grades are not ideal at this time, but he is flexible and can assemble a computer by himself. In 2000, he combined quantum mechanics with general relativity and proposed that black holes emit energy, which eventually led to the evaporation of black holes. This kind of energy is named Hawking radiation, which has attracted the attention of physicists all over the world. His new discovery is regarded as the most important progress in the field of theoretical physics for many years.

After more than ten years, Hawking's motor neuropathy made him completely lose his ability to speak and his whole body gradually became paralyzed. You can only send out "brain waves" with your eyes. Even though fate was so ruthless and cruel, he was still not knocked down by it. But bravely pursue their dreams-time in the shell and a brief history of the universe. These two books explore the origin and destination of the universe from the study of black holes, which are the crystallization of Hawking's persistence and dreams!

Hawking, your body is so tired and your soul is so strong! It is you who lead mankind to the mysterious realm of the universe. And you are not only leading, but also chasing. Chase your dream of discovery and exploration! On the way to chasing dreams, no physical torture can knock you down Your soul transcends everything.

I

Speaking of myself, I'm at a loss. What kind of person am I? The answer seems unclear to me. If you ask me who I am, I can only answer: "I am a grain of sand in the vast sea of sand."

I have a face that is not easy to remember, but a pair of delicate eyes are hidden behind glasses that look like bottle caps. My small nose and rosy lips are embedded in my white face. Because of my fair complexion, I got a glorious name "Taibai Venus". I don't think this is a derogatory term, so I readily accepted this glorious title. This shows that I am an "optimist". Nothing can make me sad, but I am very entangled, because I will cry black or be moved by a little thing. For example, I lost my cat and cried all night. Get up in the morning, my eyes are swollen like a big walnut.

Question 6: Why does Hawking speak so fast because he has made careful preparations?

Question 7: Why did Stephen Hawking say that "philosophy is dead"? Hawking's views have been criticized. What Hawking means by saying this is that when philosophers speculate on philosophy, they absorb and draw lessons from science too little. However, philosophy and science themselves answer different questions, and science is not omnipotent. Even if science becomes omnipotent, philosophy will not die out, because science is value-neutral, and at most it destroys religion.
