"Inventors and Inventions" Opens Tomorrow at Explorit
So, when was the last time you wereinside a camera?
Lately, cameras have been getting
increasingly small to the point where some clever people have invented cameras
that are petite enough to fit in your pocket so that you can have one available
for those candid snapshots. However, cameras have not always been quite so
portable. Although they are now ubiquitous, the camera is a relatively new
invention.
Explorit Science Center's new exhibition
"Inventors and Inventions Through the Centuries" has a version of an early type
of camera, the camera obscura, that you actually enter in order to use.
Although you cannot take lasting pictures with this camera, you can create and
view images using the techniques that early photographers had available to them.
And when was the last time a camera was
inside you? Arthroscopic and laproscopic surgical techiques, which allow
surgeons to insert small "video cameras" connected to wires through small
incisions in the patient, have decreased the size of incisions needed for
procedures, which makes them very good inventions from the view of both surgeon
and patient. The video microscope at Explorit, which magnifies objects 200
times, is akin to the cameras used in these surguries.
But Explorit's new exhibition about
inventors and inventions certainly isn't just about cameras. Since the start of
this millenium--and earlier--human ingenuity, often out of necessity, has
produce many useful tools and ideas. This exhibition affords you a rich
opportunity to explore creative inventions from around the world.
For example, the slide rule was
certainly not the only precursor to today's calculators and spreadsheet
programs. The abacus was invented in Asia roughly 2,500 years ago! Think that
Excel is tricky? Try your hand at doing calculations using the giant abacus on
the wall at Explorit!
Non-sighted people have had the
opportunity to read and write using an alphabet of raised dots since the 1820s
thanks to inventor Louis Braille, who was blind himself. If you are lucky
enough to be able to read text, you may have had your curiosity aroused when
you've encountered Braille in an elevator or at the ATM. Now is you chance to
try your hand (literally) at writing and reading Braille with the Braille writer
at Explorit.
These are just a very few of the
inventors and inventions represented in Explorit's new exhibition. There's the
wheel, electricity, Morse Code, a telescope, a "Rube Goldberg" machine, a
personal computer and more! And it just wouldn't be Davis if the bicycle wan't
represented.
This stunning new exhibition, partially
sponsored by Genentech, Inc., opens tomorrow. What invention will you use to
get to Explorit to experience it?

Now is the time to renew your Explorit
membership or to join for the first time! Hurry; the membership drive ends on
December 17. As an Explorit member, you'll be entitled to free admission to
Explorit and to over 225 other science museums worldwide for one year, discounts

But why the rush to join during the
membership drive? Joining by December 17 automatically enters you in the drawing
for eleven prizes, including the Grand Prize cruise and dinner on Lake Berryessa
for you and 12-15 friends. No matter when you join, you will get the
satisfaction of knowing that you are making hands-on science possible for our
community surrounding counties that Explorit enriches with its unique outreach
programs.
