The Road From Discovery- To Invention

Where does discovery end... and invention begin?

All the laws of physics were already set in place in the universe. (assembled in this arrangement)  All we had to do was find the precise combinations to be able to generate electricity, motion, atomic physics.  Sure, contraptions, machines can be invented, but __.

Isaac Newton stated, "If I have seen farther than other men, it is because I have stood on the shoulders of giants."  Modern innovators, scientists, biomedical researchers are all standing on the shoulders of giants.  But which giants?

The natural laws of the universe have been set down before time immemorial.

Isn't it (the situation) that the laws of physics already dictated that it will be this way?  And then just sat back, waiting for us to discover the methods that put it in optimal arrangement so that the "inventions" could work?  Consider medicine and pharmacology.  Sure extraction + purification methods had to be created.  But didn't the laws of physics already decree that this precise medicine would have to be administered in this dosage, in this method (muscle, intrathecal, iv)?

What I am asking is, how much of this is truly invention and originality on the part of the human being?  What percentage of it was honestly completely willed into existence by the person who worked with this system most?  On the contrary, how much of it was, at its core and essence, merely discovery?

On a similar note, how much credit should the author or creator get?  There are grammar editing software programs, there are software that supposedly "increase your creativity tenfold" like mindmapping.  There are standing mixers that mix the butter and sugar or knead the bread dough; there are graphic design digital software programs. where must the line between creativity and help be drawn?

Pondering About Homo sapiens

laws of physics in this universe. - What is it that makes our species so special?

I am not really asking rhetorically; I really do want to know.  We have opposable thumbs and we have the ability to lock our knees when standing [walk upright]. But it is the laws of physics in this universe, in the so-called "very fabric of existence" that dictate that in this universe, pertinent to this universe's laws of physics, and existing sub-subatomic particles, that opposite thumbs are a boon (put us above other species).

What about the human gift of speech?  That is great, but not on a logistic level.  Not in any way special for the purpose of giving/exchanging relaying information.  All species have some form of communication -- whale clicks, bees dancing, bats radar/sonar, etc.  These all communicate information such as warn about enemies, claim their territory, signal fear of predator species, about where food can be found.

We do however, have the ability to do more lofty things with that speech, such as create stories, write plays, novels, etc.  But that is combined with human right-side brain, which gives us panache (affinity, flair) for creativity and having an imagination.  Maybe when they say gift of speech, they are talking about things like creativity and sht.

the four main laws of the universe - strong force (explain), weak force(explain), gravity and(4th I don't remember).
