What would you regard as the most unique invention of the universe.
I think Gun is the most unique invetion as it can be used without electricity and needs no energy. Just think of a giant Machine gun just spreading bullets in every direction without getting no energy.
What are your suggestions.
That could be called as unique too.
What about electricity?
Surely, that would be the Universe itself. oooh being a pedant is so satisfying.
Apart from universe, earth, big bang and the other stuff. I am talking about inventions by Humans
A stamp for stamping eggs as they come out of the chicken's bum (attached to the chicken's bum, ow)
A device to replace car tyres with blocks of ice (vehicle travels by sliding on these blocks as they melt)
A wire shoulder mount for a ladies' mirror
These and many more were all patented too, read about it in a book called Useless Inventions (I think)
The 2nd invention was funny. The ice one.
No seriously what do you think?
I think asking what the most 'unique' invention is is wrong. You cannot have 'most unique', and all inventions with a patent are unique, maybe you mean useful? best? ingenious?
Also, things like electricity are not inventions, you discover electricity.
Y'know, I'm pretty sure a gun does involve the use of energy. I think the laws of thermodynamics would have a few complaints about a gun that could just propel chunks of matter through the air without any energy being involved in the process.
Guns use chemical energy in the gunpowwder and kinetic energy from the trigger, to create imense kinetic energy to fire the bullet. Nothing can be done without energy of some sort, thats physically impossible.
Opposable thumbs - they enabled us to use tools.
the wheel - it's unique as it has to be circular.
