    Best answer: They design and market things people wan or need. Bill Gates created the Windows Operating System. Mark Zukerburg created Facebook.

    Best answer: They design and market things people wan or need. Bill Gates created the Windows Operating System. Mark Zukerburg created Facebook. A degree has nothing to do with what a person is capable of doing. It just means they sat through endless hours of boring lectures from people who never cared if they listened or not. What you create and market doesn't even have to have any real value so long as you can convince enough people to buy it.

  • Do Surveyor's use Slide rules as part of their job? Or did they used to?

    Best answer: Surveyors used to use Slide Rules and later someone invented a portable cranking calculator called a "CURTA" which was carried in the field and used to calculate.

    Best answer: Surveyors used to use Slide Rules and later someone invented a portable cranking calculator called a "CURTA" which was carried in the field and used to calculate. It wasn't long after and the portable electronic calculator was invented and further developed into the scientific calculator. Now the calculations are made by feeding information into a hand held computer with the results being shown instantly after the information is fed into the computer. I'm a surveyor and retired from surveying 13 years ago after 36 years being a surveyor. I enjoyed my work and never woke up and wished I didn't have to go to work.

  • Is there an inexpensive DC to AC converter that also works as a rheostat?

    Is there an inexpensive DC to AC converter that also works as a rheostat? I am designing my own electric car and that would save so much work and space. so if it has a spring that always returns it to off that would be even better. if you know of one please let me know.

  • If a HUMAN is sitting on a MOVING flying carpet 2,000 ft. in the air, can he accurately drop an average sized sword on someone's head below?

    Like, seriously, let's factor everything in. Tailwinds, the weight of the sword causing it drop hilt first and likely no longer arrow dynamic, etc.

  • Why don't humanoid robot faces look completely realistic?

    Looking online at most PICTURES of humanoid robots, I don't think I've seen one that looks totally human - their faces always look slightly off. You could probably believe it was a human, but you'd think it had some kind of condition or something. Why is that? What is it about it that looks wrong?

  • Is this a series or shunt voltage regulator?

    Is this a series or shunt voltage regulator?

    Best answer: This is a series voltage regulator as the regulation element is in between input and output.

    For shunt regulator, you need the regulation element between the input and ground. The simplest one will be to use a resistor after full wave rectification and a 5V zener diode between output and ground.

  • Will adding pipe length and an elbow reduce pump performance?

    Best answer: Most manufactured pumps have pump performance curves that gauge pump performance based mostly on the head that the pump has to deliver which is partially a factor of overall pipe length, and number of elbows and other fittings. This would require considerable analysis. I would agree with most of the other... show more
    Best answer: Most manufactured pumps have pump performance curves that gauge pump performance based mostly on the head that the pump has to deliver which is partially a factor of overall pipe length, and number of elbows and other fittings. This would require considerable analysis. I would agree with most of the other responders that your reconfigure shouldn't make much difference. If you wish to reduce the effect of the added piping length, you could increase the pipe diameter.
