What is Idea: Definition and 833 Discussions

In common usage and in philosophy, ideas are abstract concepts. Also in philosophy, ideas can also be mental representational images of some object. Many philosophers have considered ideas to be a fundamental ontological category of being. The capacity to create and understand the meaning of ideas is considered to be an essential and defining feature of human beings. In a popular sense, an idea arises in a reflexive, spontaneous manner, even without thinking or serious reflection, for example, when we talk about the idea of a person or a place. A new or an original idea can often lead to innovation.

    An idea I have for better magnetic shielding....

    To try to contain a magnetic field in a pair of wires carrying a 6 volt at 2 amp current I twist the wires together. Could a braided shield surrounding those two twisted wires connected to ground help in that process? Using a braided cable such as RG 174 as a audio signal wire with the braid...

    Is portable generator a good idea?

    I'm living in Canada.. It's been one week since we have no power in our home. We are finding it very difficult to do our works without the power supply.

    How does the idea of entropy relate to something like E8

    Is this a possible idea for an antimatter rocket engine?
