What is the difference between not null and null?
In database terminology, "not null" means that a column in a table must have a value, and it cannot be empty or null. On the other hand, "null" means that a column can have a missing or unknown value, and it is not required to have a value. In other words, "not null" enforces the presence of a value, while "null" allows for the absence of a value. **
What is a null sentence?
A null sentence is a sentence that does not contain any overt lexical content, such as a subject or a verb. It is often used in linguistics to refer to sentences that are understood through context or inference rather than through explicit words. Null sentences are common in many languages and can convey meaning through non-verbal cues, shared knowledge, or previous discourse. **

There are uncountably many null sets in the real numbers, such as the Cantor set, which has the same cardinality as the real numbers and is a null set. Therefore, there are uncountable null sets in mathematics. **
