Solid Definition and 1000 Threads

In object-oriented computer programming, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible, and maintainable. The principles are a subset of many principles promoted by American software engineer and instructor Robert C. Martin, first introduced in his 2000 paper Design Principles and Design Patterns.The SOLID concepts are

The Single-responsibility principle: "There should never be more than one reason for a class to change." In other words, every class should have only one responsibility.
The Open–closed principle: "Software entities ... should be open for extension, but closed for modification."
The Liskov substitution principle: "Functions that use pointers or references to base classes must be able to use objects of derived classes without knowing it". See also design by contract.
The Interface segregation principle: "Many client-specific interfaces are better than one general-purpose interface."
The Dependency inversion principle: "Depend upon abstractions, [not] concretions."The SOLID acronym was introduced later, around 2004, by Michael Feathers.Although the SOLID principles apply to any object-oriented design, they can also form a core philosophy for methodologies such as agile development or adaptive software development.

    Can CO2 in the Earth's atmosphere sublimate into a solid?

    CO2 becomes a solid at -78.5 C or -109.3 F. The coldest temperature ever recorded on Earth was on Antarctica at -89.2 C or -128.6 F. So is it possible for CO2 to literally freeze out of Earth's atmosphere under certain conditions? If not then why not?

    Is Solid Residue Present in Pure Water?

    Hi everyone! If I have a sample that didn’t present conductivity and left a solid evaporation residue but its density is approximately 1 g/mL (1,08 g/mL), can I still say it is pure water? I suppose pure water shouldn’t have any kind of solid residue. Thanks!

    I Why do protons and nuclei of light elements not ionize solid objects like metal?

    When protons or nuclei of light elements like Helium passes through gas, it ionises the molecules on it path. But that's not the case when proton or nuclei of light elements pass through solid objects like metal. What's the reason behind that?
