SQRRR or SQ3R is a reading comprehension method named for its five steps: survey, question, read, recite, and review. The method was introduced by Francis P. Robinson in his 1941 book Effective Study .
Science Research Associates Inc. was founded in 1938 [1] with a trade and occupational focus. In 1957, it moved into individualized classroom instruction with the iconic SRA Reading Laboratory Kit, a format that they translated to mathematics, science, and social studies [1] commonly called SRA cards.

The empty set is the unique initial object in Set, the category of sets. Every one-element set is a terminal object in this category; there are no zero objects. Similarly, the empty space is the unique initial object in Top, the category of topological spaces and every one-point space is a terminal object in this category.
A structural type system means that the language decides whether types are compatible and/or equivalent based on the definition and characteristics of the types. Type checking determines whether and when types are verified. Static checking means that type errors are reported based on a program's text (source code).
Whereas in Effective Study, he suggests to do this for each passage. So Survey whole chapter, then on first passage Question, Read, Recite, repeat for each passage, then Review at end of chapter. I think we should stick to the original Effective Study SQ3R and possibly mention the variations.
In fact, by the existence theorem for limits, all finite limits exist in a category with binary products and equalizers; equivalently, all finite limits exist in a category with terminal object and pullbacks (by the fact that binary product is equal to pullback on the terminal object, and that an equalizer is a pullback involving binary product).
In mathematics, a characterization of an object is a set of conditions that, while possibly different from the definition of the object, is logically equivalent to it. [1] To say that "Property P characterizes object X" is to say that not only does X have property P, but that X is the only thing that has property P (i.e., P is a defining ...
A circular shared_ptr chain can be broken by changing the code so that one of the references is a weak_ptr. Multiple threads can safely simultaneously access different shared_ptr and weak_ptr objects that point to the same object. [11] The referenced object must be protected separately to ensure thread safety.
