The camera obscura.
Explanation:
The camera obscura was first invented by the Arab scientist Ibn al-Haytham. This was the first approximation to what we know today as a digital camera.
The camera obscura was a black small box (or a room) with a small hole in one side, that allows light to get through, this projects the image in the outside to one of the walls of the box; hence, a 2D projection of a 3D object.
Around 700 years later, the Italian painter Leonardo Da Vinci also used this device to work on his arts and invested a lot of time into improving its design.
Answer:
-A small boy has to be reminded over and over not to pet strange dogs without permission.
-A pre-teen with diabetes resists being taught how to give herself insulin injections
Explanation:
A small boy has to be reminded not to pet strange dogs is likely to stem from the fact that he is quite young(has not developed all mental capacities)and wouldn't heed easily to instruction(reminding orally) and therefore be reinforced in this manner. At this stage children learn more unconsciously than consciously and so instructions are less effective. The same would likely apply to the pre-teen here.
