Week 24 – #14 Enclosed

14 Enclosed-1

Enclosed in the case is Edison’s scale.  On the table next to the case are other tools and instruments he used, such as his microscope.  This was taken at the Edison – Ford Winter Estate in Ft Myers, FL in Edison’s lab where he was trying to find a plant that could help produce rubber.

  1. Great shot Sue for theme. I have been to the museum several times over the years with different family members when they have joined us on our yearly vacation on Sanibel Island. I always see something different every time I go. The grounds are especially beautiful.

  2. As having a degree in Chemistry I have a great appreciation for the shot in his laboratory. Do you know why the scale is enclosed? There is significance to it being enclosed. Gary

      1. This is an Analytical Balance, measures in grams and micorgrams. 1 gram is about 0.0022 pounds. Any air currents would make the balance reading unstable and therefore it is open and closed when adding or removing things that are being weighed. This particular type is counterbalanced, meaning you have an exacting weight on one side and balance it against the substance that you are weighing. The scale above it would allow you to measure weights that are not exact to the exacting weight. Todays equipment is all digital and you only have to put the thing you are weighing on the balance pan and get an exact weight. I know too technical, but that is me. Thanks for letting me expound. A good balance today would run around $2,500, the price of a good camera and lens. Gary
