For a small child, understanding the concept of time and its passage is very difficult. As a result, children are often impatient when expecting something or confused when trying to remember something from the past. They live in the present, and learn the notion of time only little by little. But accepting the passage of time, and the reality of aging, is something that plagues us even as adults. The lucrative cosmetic and plastic surgery industries show how humanity seeks to control or deny the passage of time, an urge that has proved to be relentless.

Within architecture, water evokes sentiments of calmness and wellbeing. The element has influenced design through its dynamic and fluid nature. With recent technological advances, architects have created some of the most strategic, innovative, and unexpected intersections of design and H2O.

Below, we have provided a roundup of indoor pools that highlight the application of water in different spaces, showing its relationship to materiality and use.

The key to successfully designing or recovering public spaces is to achieve a series of ingredients that enhance their use as meeting places. Regardless of their scale, some important tips are designing for people's needs, the human scale, a mix of uses, multifunctionality and flexibility, comfort and safety, and integration to the urban fabric.

To give you some ideas on how to design urban furniture, bus stops, lookouts, bridges, playgrounds, squares, sports spaces, small parks, and urban parks, check out these 100 notable public spaces.

Let us return to the first architecture class on structures and the classification of structural efforts. In most structures, whether natural or man-made, compression forces are the primary actors. These are efforts undertaken with equal and opposing loads, applied in the interior of the structure, which tend towards the shortening of the piece in one direction - or compressing it, as the name indicates. It is not difficult to find examples of this: for example, a stone wall or a wooden log can resist the weight of a covering through internal compression efforts that are inherent to each material. Tension efforts, on the other hand, tend to lengthen components in the direction of the applied force of action. Steel, for example, is a material with good tensile strength. It is used in reinforced concrete precisely in the parts where the piece is in traction. But it is also possible for a structure to only have tensile parts, as is the case of membrane, tensioned, or tension structures, which consist of surfaces pulled by the action of cables or ropes in which the masts absorb compression efforts.
