Bill Nye the Science Guy

There were many, incredible, life changing inventions through science that have lead to hundreds of other discoveries, and these are just a few of the ones I observed.

Periodic table: was invented to teach students about the elements and
after all of the know Chemicals were written down, it was discovered
that many of them have similar qualities. That now makes up the
current periodic table.

Electricity: First in this experiment, pot ash was melted. He ran one of his biggest battery to
the pot ash and it burned and pure potassium was the result. This was the beginning of finding out what elements made up a structure.

1850's-different items burn in different colors when under great heat.
Specrascope was placed over a flame and many colors were present. Every
element burns a different color. They found that when they did the
same thing with the sun, there was the color for sodium in the sun.

JJ Thompson found that one could find a particular piece of an atom.
He was using a crooks tube in his experiments. 1897 when the crooks
tube is used as he used it, he found that what he saw was the electron
stream.

Gilbert Luis began the revolution of compounds.


X-Rays radiation. A number of scientists found that...
1896 various minerals created radiation. (uranium) paper, uranium, photo sheet.


Curry: tried to identify which elements made uranium radioactive and
found two new elements.

Alfa and beta particles and gamma rays; they have given us the ability
to know how old the earth is and power our satellite in space

Johns hiat discovered plastic. Polymers are atoms that are powerful
and creates fibers that are much stronger than natural fibers.

Buckey Balls the molecules are clusters. Carbon nano tubes are the
stiffest materials in the world. 100 times stronger than steel. Can be
used for almost anything.nano technology is creating an object or
molecule from scratch. The atoms have to self assemble.
