The question you asked is from the 8th grade California Physical Science textbook pg 446 #19. You are one retard for not knowing the answer. Go f**k yourself. You don't deserve to pass this class. Go die in a hole.
Theoretically it is impossible. Many have tried and many continue to attempt to develop a perpetual motion machine. Only if there is no friction and no energy is lost to the surroundings, would perpetual motion be possible... No. Such machines are not possible, although until the end of mankind people will perpetually try to imagine or create one.
the atom
yes
No. There is no known way to make living things or common objects invisible. Given the way that light behaves and the way that matter is composed, it is very unlikely that any such thing will ever be possible. The best that technology can do is develop new ways to camouflage objects.
You can develop a general theory of the dynamics of turbulent flows and the motion of granular materials.
Nothing.
through observation and reasoning
based on observation of what is wrong with the work of other scientists
furthur explanation about the books theme.
It showed that fixed air is carbon dioxide.
Nothing. A hypothesis is just a guess as to a possible explanation of something. If it's wrong, it's wrong. No big deal. If you still desire to explain the thing, you should develop a new hypothesis.
I think it is possible that you can develop a kind of power similar to clairvoyance.

The Maya studied astronomy, calendrics, agriculture, and the movements of celestial bodies from observation. They built impressive observatories and used their knowledge to develop sophisticated calendars and accurately predict celestial events.
