Чтобы избежать плохой архитектуры, рекомендую освоить принципы SOLID и писать код в соответствии с этими принципами. SOLID (single responsibility, open-closed, Liskov substitution, interface segregation, dependency inversion) — это пять принципов объектно-ориентированного программирования. Это набор правил, которым нужно следовать при создании структуры классов. Я советую подробнее узнать об этих принципах и других важных аспектах красоты кода, прочитав книгу Роберта Мартина «Чистый код».

Question
[default - edit me]
Answer

I'm not sure if this answers your question, but if you are looking at graphs of real valued-functions, you could describe the graphs of f f f and g g g as "touching" at a point x 0 x 0 x_0 if there is a neighborhood I I I of x 0 x 0 x_0 with the property that f ( x ) ≥ g ( x ) f ( x ) ≥ g ( x ) f(x) \ge g(x) for all x ∈ I x ∈ I x \in I and f ( x 0 ) = g ( x 0 ) f ( x 0 ) = g ( x 0 ) f(x_0) = g(x_0) . Thus the graphs intersect but can't "cross" as the value of g g g never exceeds that of f f f .

Interestingly if f f f and g g g are differentiable and their graphs touch at x 0 x 0 x_0 in this sense then it must follow that f ′ ( x 0 ) = g ′ ( x 0 ) f ′ ( x 0 ) = g ′ ( x 0 ) f'(x_0) = g'(x_0) simply because f − g f − g f - g attains its minimum value at x 0 x 0 x_0 .

I never though about an analogy to space curves but now I'm curious.
