The question of whether a device will come into being depends upon three things: first, whether there is a practical use for it that warrants its development and manufacturing costs; second, whether the laws of physics applying to the elements available for its design allow the attainment of the needed ranges, sensitivities, or the like; and third, whether the pertinent art of manufacture has advanced sufficiently to allow a useful embodiment to be built successfully.
About this quote
- What does it mean?
- A device will only be created if there is a practical use, if physics allows it, and if manufacturing technology is advanced enough.
- In plain terms
- Devices get built when they are useful, physically possible, and manufacturable.
- What can you take from it?
- Build only when there is a need, a physical possibility, and the means to make it.
