In 2012, Apple managed to make a screen for mobile terminals that has 9.7 inches and a resolution of 2048 x 1536 pixels and this is a real achievement from a technological point of view. To mark the event, those from the famous American museum Smithsonian presented the image above in which we have the concept of a microfilm projector. The concept was published in a scientific magazine in 1935 and presents a way by which a user can watch microfilms right at home, but we are talking about an extremely complex technology for that time.
It has proven possible to photograph books, and throw them on a screen for examination, as illustrated long ago in this magazine. At the left is a device for applying this for home use and instruction; it is practically automatic.
Making a comparison with today's tablets and the technology of that time, we realize how much humanity has evolved in less than a century, and I, for one, look to the future with great confidence.
