There is an Arabic saying that the soul travels at the pace of a camel. While most of our self is led by the strict demands of timetables and diaries, our soul, the seat of the heart, trails nostalgically behind, burdened by the weight of memory. If every love affair adds a certain weight to the camel's load, then we can expect the soul to slow according to the significance of love's burden.
Saudade is a deep emotional state of nostalgic or profound melancholic longing for an absent something or someone that one cares for and/or loves. Moreover, it often carries a repressed knowledge that the object of longing might never be had again.
Choi: I love [this contemporary banana cream pie] because sometimes new presentations create that iconic or nostalgic thing, but then they don't taste like nostalgia. But this one tastes like a banana cream pie.
Puck: So many young chefs today forget that food has to be delicious. If it's not delicious, why do it? If it's just interesting, you go once, that's it – "okay, I get it, but I don't want to go back."
Choi: I hear you chef. That's what I teach my cooks. I say, "You can do anything you want, but if you can't beat a banana cream pie, then the banana cream pie still wins." In most cases they don't. They can't beat the original.
Engineers seem to have a clear, if usually implicit, model of the process of design. It is usually an orderly model of an orderly process as the engineer conceives it.
The notion that the design process should be modeled as a systematic step-by-step process seems to have first developed in the German mechanical engineering community.
Herbert Simon independently argues for design as a search process in The Sciences of the Artificial. He was motivated to lay out a strictly rational model of design precisely because such a model was a necessary precursor to automating design. His model remains influential even if today we recognize the "wicked problem" of original design as one of the least promising candidates for AI.
In software engineering, Winston Royce independently introduced a seven-step Waterfall Model to bring order to the process. In fact, Royce introduced his waterfall as a straw man that he then argued against, but many people have cited and followed the straw man rather than his more sophisticated models. Even if ironically, Royce's seven-step model must be considered one of the foundational statements of the Rational Model of Design.
