Panorama of, cognitive spaces used to capture the larger scale. The device of the panorama existed in painting, particularly in murals, as early as 20 A.D., in those found in Pompeii, as a means of generating an immersive 'panoptic' experience of a vista. This novel perspective was quickly conveyed to America by Benjamin Franklin who was present for the first manned balloon flight by the Montgolfier brothers in 1783, and by American born physician, John Jeffries who had joined French aeronaut Jean Pierre Blanchard on flights over England and the first aerial crossing of the English Channel in 1785.

Tradeoffs for locomotion in air and water balloons. By changing the amount of gas in these swim bladders, fish actively control their density. If they increase the amount of air in their swim bladder, their overall density will become less than the surrounding water, and increased upward buoyancy pressures will cause the fish to rise until they reach a depth at which they are again at equilibrium with the surrounding water. In this way, fish behave essentially as a hot air balloon does in air. Some seabird species utilize surface feeding or plunge diving during foraging in which gravity and/or momentum is used to counteract buoyancy effects
