No, Evolution will always be a theory. Observable changes over time
can be facts.


The first electron microscopes appeared in the late 70s and early
80s that enabled us to see atoms for the first time. I guess that
means that before we actually 'observed' them, the existence of
atoms was a theory too? You need to take a science class again, Arny.

but electron microscopes cannot 'see' atoms. About the best they can
manage is to 'see' are some of the larger molecules.


Agreed.

Furthermore as I showed in another post, the Electron Microscope was
invented in the late 1930s, about a half a century earlier than Schizoid Boy
thinks it was.

Atoms can only be 'seen' by a scanning-tunnelling microscope (so far).
Invented by
IBM, as I recall, who rearranged a few dozen atoms to form the company
logo.


Again agreed that the scanning-tunnelling microscope can view and manipulate
atoms.

"The same principle was later used in the scanning tunneling microscope. The
remaining barrier to the development of that instrument was the need for
more adequate vibration isolation, in order to permit stable positioning of
the tip above the surface. This difficult problem in mechanical design was
surmounted through the work of Gerd Binnig and Heinrich Rohrer, IBM Research
Laboratory, Zurich, Switzerland, who in 1986 shared in the Nobel Prize in
Physics for their discovery of atomic resolution in scanning tunneling
microscopy. In their announcement of the award, the Royal Swedish Academy of
Sciences recognized the pioneering studies of Russell Young."

Those are single atoms on there, pals. But more on that in a minute.

He never claimed that it was invented in the late 70s and early 80s.
He said this:

The first electron microscopes appeared in the late 70s and early 80s
*that enabled us to see atoms for the first time*.

This is speaking of a specific type of electron microscope. I guess
you stopped reading before the word "that".

Atoms can only be 'seen' by a scanning-tunnelling microscope (so far).
Invented by
IBM, as I recall, who rearranged a few dozen atoms to form the company
logo.

Then how can you agree with the statement:

"but electron microscopes cannot 'see' atoms. About the best they can
manage is to 'see' are some of the larger molecules".

http://physics.nist.gov/GenInt/STM/text.html

"The same principle was later used in the scanning tunneling microscope. The
remaining barrier to the development of that instrument was the need for
more adequate vibration isolation, in order to permit stable positioning of
the tip above the surface. This difficult problem in mechanical design was

You see, according to Nobelprize.org:

"The Scanning Tunneling Microscope
The scanning tunneling microscope (STM) is a type of electron
microscope that shows three-dimensional images of a sample. In the
STM, the structure of a surface is studied using a stylus that scans
the surface at a fixed distance from it".

Ooops, pedantry shot down in flames. Sorry guys, you lose. Trumped by
the good folks who bring you the Nobel prize.
