How is reducing the aperture of an inexpensive camera reduce the amount of spherical aberration?

Bananas make the spherical aberration very elongated and yellow, therefore causing the aperture to reduce and the spherical aberration to completely stop.

How does the surface area change when a large cell gets smaller but has the same total volume?
The surface must get more spherical. When it reaches a perfect sphere the surface area cannot be reduced without also reducing the volume.
How is plastic a boon?
Plastics were originally a boon because they provided an inexpensive packing option reducing the use of paper and glass. They are also used extensively in computer technology and have been used very successfully in the health industry.
How would you 'stop'the action during a sports match?
All shots rely on three settings - the shutter speed, aperture (lens opening) and ISO or film speed. The first, shutter speed, is the most important to stop the action. Putting the camera in a sports mode effectively shortens the length of time the shutter is open, reducing the motion blur in pictures. This can be done manually by letting more light into the camera either by making the aperture larger (lower f/ number) or raising the ISO.
What does stopping down mean in photography?
The following applies to an SLR and may not apply to a DSLR. It can mean either: a) simply reducing the light transmitted to the film or camera sensor by way of adjusting the aperture so that it is smaller. b) manually reducing the aperture from full-open before taking the picture to either i) preview the depth of field through the viewfinder or ii) take a meter reading at the aperture that will be used for the shot in order to arrive at the corresponding shutter speed or iii) take the shot with the aperture stopped down, forcing the camera meter to calculate the shutter speed at the moment of exposure. The latter two are referred to as stop-down metering. To do so and allow ambient light to enter the viewfinder eyepiece (say, because you mount the camera on a tripod and stand back from the camera) would be a mistake since light entering the eyepiece will alter the meter reading. One reason for performing stop-down metering is because the lens has been attached to the camera body by means of a reversing ring. In this case, the lens levers and pins cannot transmit the aperture information to the camera in order for the meter to calculate the exposure. Not all cameras have stopped-down metering capability, for sure. My old Canon A1 does, and has a lever controlled metal blind that covers the eyepiece to prevent stray light from entering.

Why does liquid take the shape of a sphere when in zero gravity and gases does not?
It is due to surface tension. Surface tension is only for liquids. Due to surface tension surface energy is to be minimized only reducing the area. For a given volume sphere has minimum surface area. Hence spherical shape.
