  1. Yes, a fictional and very funny character.
  2. So are you saying Howard Wolowitz isn't a scientist?
  3. An engineer is a specific type of scientist. The term "scientist" is very broad, an engineer is just a specific type of scientist, there are many different types of scientists. Not all scientists are engineers but engineers are all scientists, of a type.
  4. An engineer is a scientist. The Wright Brothers were engineers, so there you have it, an engineer is a scientist, a type of scientist. And I do believe the Wright Brothers did become relatively wealthy from their airplane inventions. From early on Jeff Bezos displayed scientific interests and technological proficiency and he graduated college with a Bachelor of Science in Engineering degree in electrical engineering and computer science. Elon Musk graduated with a Bachelor of Arts degree in physics. Bill Gates took computer science courses. I woul
  5. For somebody with a passion for science, it can, in my opinion, be a very rewarding career. Also, there's lots of wealth in a career as a scientist, indeed you can make mountains of money. Something that is inaccurate, I believe, about the fictional character of Sheldon Cooper, is that he isn't rich. He lives in an apartment that he shares with Leonard. A good scientist should be rich enough to be able to live in a mansion. Im not saying a scientist necessarily would live in a mansion, just that a good scientist should be able to afford to live very well if one wants to. Take for instanc
  6. Who would've thought that the inventions of Charles Babbage and Alexander Graham Bell would be merged and miniaturized. Now, if we could only do the same thing with the inventions of Henry T Ford and the Wright Brothers.
  7. So having electric engines would be less polluting, not just in terms of emissions but in terms of other factors such as friction.
  8. Motors for any kind of gas or electric machine be it a car, lawnmower, ect.
  9. Well I don't see why such pollutants would be any worse in an electric motor than they would be in a gasoline motor. So is there any point to having smoke stacks?
  10. In terms of electrical systems causing pollution, I do know that electricity creates ozone which I believe can be harmful at ground level. I don't know about any other harmful emissions or pollutants created from electricity.
  11. It is common knowledge that burning fossil fuels can be harmful to the environment. However, if we are going to burn fossil fuels I believe there are ways to do it that are less harmful. For instance, smoke stacks. With smoke stacks you don't have ground level pollutants. Ground level pollutants are more harmful than pollutants way up in the air which is why I believe factories are required to have them. However there are some machines that burn fossil fuels that will result in ground level pollutants the most obvious being cars and trucks. Other gas operated machinery such as lawnmowers, leaf
  12. From what I know, when you melt down rusty metal the rust floats to the top. However, I heard that with smelting there are chemical procedures to actually reverse the rusting effect, that after melting down the metal they will somehow turn the rust back into its natural form. Rust forms when oxygen combines with the metal so supposedly there's ways to remove the oxygen from the rust. This reversal process I believe involves the use of chemicals.
  13. If the Earth was the size of a tennis ball, this video explains the size and scale of the universe. This video will make you feel very small.
  14. How about a water wheel, isn't that harnessing gravity to power a motor? If you've got a waterfall and you build a water wheel, you're using gravity to make the wheel move.
  15. So its the Kelvin scale that's used in Physics.
