Le Compendium

    At the origin of "Le Compendium", there is certainly a desire to present a collection of ancient scientific instruments belonging mainly to the domain of Education, but there is also the need to highlight the most modest of them such as the pocket microscope. It is about small forgotten or underestimated objects that are found today in garage  sales and flea markets. Lingering over these objects, apparently unpretentious, one realizes the ingenuity which is displayed by their creators.

    Speaking about devices more impressive, such as the motor with electro-magnets, the spectrograph with quartz prism, or about the small device for observation that is the floroscope, we should not let them disappear.

    After visiting "Le Compendium", you can, of course, leave me a message and give me your opinion.
