This question already has an answer here:
I read the book
The Not So Short Introduction to LaTeX, and found this line:
LaTeX: Tilde '~' generates a space that cannot be enlarged and...
It seems that the tilde make the space smaller when I compare
Question 1: When shall I generate a space that cannot be enlarged?
In addition, same in the section
The Space Between Words, there is a line:
If a period follows an uppercase letter, this is not taken as a sentence ending,...
However, no matter uppercase or lowercase I follow a period, I cannot find something different.
Question 2: Can anyone show me an example?
The command \@ in front of a period specifies that this period terminates a sentence even when it follows an uppercase letter.
Similarly, for those two lines, I cannot find any difference.
I am new to Latex\@. And you?
