question:Some of Baird's early inventions were not fully successful. In his twenties he tried to create diamonds by heating graphite and shorted out Glasgow's electricity supply. Later Baird invented a glass razor, which was rust-resistant, but shattered. Inspired by pneumatic tyres he attempted to make pneumatic shoes, but his prototype contained semi-inflated balloons, which burst. He also invented a thermal undersock (the Baird undersock), which was moderately successful. Baird suffered from cold feet, and after a number of trials, he found that an extra layer of cotton inside the sock provided warmth. Baird's numerous other developments demonstrated his particular talent at invention. He was a visionary and began to dabble with electricity. In 1928, he developed an early video recording device, which he dubbed Phonovision. The system consisted of a large Nipkow disk attached by a mechanical linkage to a conventional 78-rpm record-cutting lathe. The result was a disc that could record and play back a 30-line video signal. Technical difficulties with the system prevented its further development, but some of the original phonodiscs have been preserved, and have since been restored by Donald McLean, a Scottish electrical engineer. Baird's other developments were in fibre-optics, radio direction finding, infrared night viewing and radar. There is discussion about his exact contribution to the development of radar, for his wartime defence projects have never been officially acknowledged by the UK government. According to Malcolm Baird, his son, what is known is that in 1926 Baird filed a patent for a device that formed images from reflected radio waves, a device remarkably similar to radar, and that he was in correspondence with the British government at the time. The radar contribution is in dispute. According to some experts, Baird's "noctovision" is not radar. Unlike radar (except Doppler radar), Noctovision is incapable of determining the distance to the scanned subject. Noctovision also cannot determine the coordinates of the subject in three-dimensional space. Answer this question "Were there any problems with it?" by extracting the answer from the text above.

question:Question: I can use this background: When you go to the dentist to get a tooth pulled, you really don’t want to feel any pain. The dentist injects an anesthetic into your gum and it eventually becomes numb. One theory as to why anesthetics work deals with the movement of ions across the cell membrane. The anesthetic gets into the membrane structure and causes shifts in how ions move across the membrane. If ion movement is disrupted, nerve impulses will not be transmitted and you will not sense pain – at least not until the anesthetic wears off. Now, I have a new situation: Jake and his brother Jordan both have to go to the dentist to get a tooth pulled. Jake is allergic to the anesthetic unfortunately, so he has to have the procedure done without it. Jordan isn't allergic, so he is able to get his tooth pulled after an anesthetic is injected. Answer this question please: Who will not experience a disruption of ion movement in their cell membranes? Answer:

question:Given the question: Article: About ten men in every hundred have the trouble of color blindness in some way. Women are luckier, only about one in two hundred is affected in this matter. Perhaps, after all ,it is safer to be driven by a woman. There are different kinds of color blindness. For example, a man cannot see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can't tell the difference between blue and green. Only a few unlucky men may see everything in shades of green-- a strange world indeed. Color blindness in human beings is a different thing to explain. In only one eye there are millions of very small things called "cones " . These help us to see in the bright light and to tell differences between colors. These are also millions of "rods" ,but these are used for seeing when it is nearly dark. They show us shapes but not colors. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky. With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of the rods we can see shapes at night. Question: We can attract and kill mosquitoes by using a _ light. Yes or no, is the answer "blue"? The answer is:

question:Read the following conversation and answer the question. W: Good morning. Sit down please, Mr. Johnson. M: Thank you, madam. W: I have read your letter here. You seemed to have done very well at school. Can you tell me something about your school work? M: As you can see, my strongest subjects were arts subjects. My best subject was history and my second best was geography. However, my favorite subject was math, and the results I got in the math paper were quite reasonable. W: That's true. Now, can you tell me why you think these subjects will help you in this job? M: Well, madam, I understand that you manufacture computers, prepare software, and advise clients on how to use them. Is that right? W: That's right. M: And I've been told that working with computers needs a logical mind rather than great skills in mathematics. That's especially true, I believe, when it comes to writing programs. So I think my results show that I have some ability in logic and in mathematics as well. W: So, you would like to write material for computers, would you? M: Yes, madam. That's what interests me most about computers - writing programs, but I think the computer industry itself is still expanding enormously. I'm sure that career prospects in the industry would be very good no matter what sort of job I went into. W: I see, well, thank you. I've enjoyed our talk. We'll be writing to you. M: Thank you, madam. Good morning. Question: Mr. Johnson thinks that ________ can help him a lot in the job. - logic - writing - history Answer:
