4: I have to study a scientist in a certain field and my question is , can you give me any names of people who are involved in the history of the computer?
5: In our Biology class we are doing a paper about a scientist and how they have changed a particular science. We were instructed to seek you out for help in finding a scientist. I would appreciate it if you could respond with a scientist that has something to do with the modernization of computers. Thank you
6: How does a computer's screen work?
7: V.B. - Visual Basic I am trying to write a install program using visual basic, it might be under the engineering department, I was wondering if you guys could maybe do it for me? It would be very appreciated
8: At home we have the Internet. It comes through the same cable that hooks to our TV. My neighbors have the Internet too, their mom has a lab top computer that she can move anywhere around the house. She gets the Internet to on her labtop but it is not hooked to any wires. My dad says they have a wireless LAN. Question 1: How does she get the Internet with no wires? Question 2: If we don't need wires for the Internet then why do people spend money buying them? Question 3: Is it the same Internet that people get on their cell phones?
9: How does a computer work?
10: Q1.Who invented the internet? Q2.Who invented the website, and the computer?
11: Could you please tell me if is it possible to replace telephone lines by electromagnetic waves such as tv broadcasts, so that one would access the internet anywhere simply by the help of an antenna like he does the same while he wishes to watch TV? Without any cables I hope you can get my question. And thanks in advance for your kindness.
12: Consider if it is possible to store information in a linear system?
13: Does electronic mail use any electromagnetic waves eg. radio waves for tranmission of information, e.g. emailing overseas?
14: How do computers work?
15: How do you create a programming language?
16: What are the definitions and functions of operational computers, diodes, transistors, transformer to an fm component?
17: I am a Mechanical Engineering student and I want to know simulation process of robots. Could you help me with knowledge about the hardware connections?
18: Hi! How could I, (or what would I need, too) to make a relatively simple search engine of my own?
19: Hi, I read an article the other day about an artificial retina that nanotechnologists have recently created. I really liked it and all, but I was wondering how something like that could work. My sister who is in college now told me about brain input and output signals that are recived from electronic sources, such as the artificial retina. How would a blind person be able to "remember" what they saw with the artificial retina? If the artificial retina does not have direct contact with the part of the brain that stores information, how is seeing something, and (knowing you have seen it) possible?
20: Um, I bet this question is going to be common sense, but i have always wondered about it. How does something that is concrete, is it able to become an electronic file stored on a computer? How does a simple code make something happen on a computer?
21: What are your views on pesticide use? Do you think their use is dangerous to the environment? If so, what do you suggest we do to decrease pesticide use?
22: Are lithium polymer batteries dangerous? Why?
23: If a human had been uploaded with a computer program, how could one test his brain to prove it, and determine who the originator of that program was?
24: How is that a computer can make fast calculations?
25: How many circuits can you fit in the computer called MINAC (Miniature Navigation Airborne Computer)?
26: What is the difference between computer digital signals and T.V. analog signals?
27: My partner has a Nintendo 64 and I have a Playstation. So we decided to do our science project on memory-cards . We wanted to know how they are flawlessly working and how they can store so much memory if they are only about 3 inches in length .
28: How do 3-D computer graphics work? I am interested in how to design the graphics. How it is different on a computer from "2D"?
29: Can you help me find information on my title: Can a Magnet Erase a Cassette Tape, Floppy Disk, and a Compact Disk, what kind of magnet is used to do so and, how does it erase?
30: I am currently participating in a project where I have to design a space settlement. I would like some data on quantum computing.
31: How do computers contain so much information in them? They are so small, but we are bigger and contain less information?
32: How do scanners work? How do they work to process the information and send it to the computer?
33: How can a little computer chip do all kinds of things? How can a little chip in a computer have that much information?
34: How do CDs work?
35: I have read that Josephson junctions are used in supercomputers. I read that these superconduction circuits used a special material as a cunductor, and it also said in the article that the speed of these computers can be measured in 100s of gigahertz. My question is what is limiting these supercomputers from going into mass production? Does it have something to do with cooling or energy use? Does it have something to do with the size of these computers?
36: I have a question about data storage in the hard drives of computers. I was rreading an article that said that at a certain small grain size, the magnetic grains of a hardrive will spontaneously loose their charge I was wondering whether or not this affect would happen if the hardrive was contained in a vacuum. If it is possible to create such a small vacuum, then could it be possible to use this idea to create a new, extremely high capacity, hard drive using a vacuum?
37: I'm wondering why, on a computer, red (R), green (G), and blue (B) together make white, but cyan, yellow, and magenta make dark gray. Then you have to add black (K) to make a complete black, but in RGB you don't need an extra color to make white.
38: I am working on a science project about how color affects taste and I was wondering if you could connect me with someone who knows a lot about this topic that i could interview via email. I would be asking questions like, are there any flaws in how i set up my experiment? What do you think is the most efficient way to test this hypothesis? and also some questions about the topic itself.
39: Do any aliens exist? Does any planet have conditions to live?
40: What is meant by Morse Code?
41: What evidence supported Wegener's theory of continental drift?
42: What exactly is heat?
43: Why only silicon chip is used in computers? Does it have any special property?
44: Why do crystals form in water? What do you do in your lab with others? Me and my dad are interested in what you do.
45: How does space never end?
46: Why do we think the way we do? What is it in our brains that allows us to not only process information, but allows us to imagine or have emotion? Theoretically, what would separate a naturally developed brain from one 3d printed from stem cells in terms of thought?
47: How can you find glitches in programming without having to go through it manually and run the program a lot?
48: Could you explain to me in a simple way what the scientific base for quantum computers is? What is the difference between them and the computers we use nowadays? When will we be able to use quantum computers? Thank you for your time.
49: Does the study of crystals include copper sulfate crystals? Are copper sulfate crystals salt crystals rather than protein crystals and therefore not as useful?
50: New Orleans was able to prepare for Hurricane Katrina. How were they able to predict that this hurricane was coming?
51: Can you explain in simple words how the quantum computer works?
52: Dinosaurs today and paleontologists using robotics and computer based technology to learn about them more than ever before.
53: Are quantum computers going to be programmed in the same way as normal computers of today?
54: Will cybernetic enhancements ever be more than just arm and legs and be like computer chips in your brain like science fiction movies?
55: What data type is being used for computer images? I know it will all ultimately be converted to bits. I want to know as a user, which data type should be used to store such information. Also, I want to know how the CPU works to change the given data into bits, and what data type will be good for the CPU to easily change the given data. Thanks!
56: Why does c++ have long and int (4 byte integers)? Why have two words for the exact same data structure?
57: How does Tor work? I heard it's like a super VPN.
58: Why is it that early computers had green text?
59: In c++ when we have an a && b, then if a is false, b isn't considered. Does something similar happen when we have a && b &&c?
