Zacharias Janssen made
the first crude
compound microscope.In the mid 1600s
Anton Van
Leeuwenhoek
made the first simple
microscope using
a glass
bead for a lensRobert Hooke used the
term cell to discribe the
empty boxes seen in corkTheodor Schwann studied
animal cells and determined
that all animals were made
of cellsRudolph Virchow hypothesized
that cells don't form on their that
cells divide to form new cellsMatthais Schleiden studied
plant parts and determined
that all plants are made of
cellsAn important discovery with
microscopes is that
lenses combining two types of
glass could reduce the chromatic
effect, with its disturbing halos
resulting from differences in
refraction of light.Gerd Binnig and Heinrich
Rohrer invent the scanning
tunneling microscope that
gives three-dimensional
images of objects down to
the atomic level.The Human Genome draft was
completed, laying success stones
for the project which was completed
in April 14, 2003. The project
succeeded sequencing and
mapping of human genome
with a 99.99 percentage.
