what do the inventors first do when they discover or make a new thing and why?
Answers
ᴀɴs. Inventions are useful, practical creations of the human mind. All our minds work in roughly the same way, so it's not really surprising that different people can have similar ideas for a problem-solving invention at almost exactly the same time.
ᴀɴs. According to the well-known saying, "necessity is the mother of invention"; in other words, people invent things because society has difficult problems that need solving. There's some truth in this, though less than you might suppose. It would be more accurate to say that inventions succeed when they do useful jobs that people recognize need doing. But the reasons inventions appear in the first place often have little or nothing to do with "necessity," especially in the modern age when virtually every need we have is satisfied by any number of existing gadgets and machines.
