Architecture is what we build by combining natural shapes and the structure of our own physical selves. We put ourselves "into" our buildings, and they have an impact on our surroundings as they work back on us. This is why artists love architecture - it allows them to express themselves through their use of shape and material. Also, architects are artists who design buildings, so they naturally develop similar skills in other artistic fields, such as painting or sculpture. Architecture is also a science that uses mathematics and physics to design structures. As with other sciences, engineers have developed tools to help them predict how structures will behave under certain conditions. Engineers are also trained in art, which helps them understand what kind of shapes would be effective at expressing ideas within structures. Finally, architecture is a very personal thing. Each building influences the people around it, so it has the potential to cause good feelings or bad ones depending on how it is used. For example, a beautiful building designed by a famous architect can make someone feel important even if they aren't an owner, while a boring office block could cause dissatisfaction with the local council for denying it a face-lift. Architecture is therefore responsible for some people feeling proud or ashamed depending on how they perceive it. This is why artists love architecture - because it is such a powerful tool for expression and understanding of the human condition.
