After watching a number of YouTube videos and consulting several math books your video here did the trick and helped me to see just what a bases is where I think I now understand what that means. Thanks! Great video!

Thank you! Your videos are great and very helpful! Keep it up!

@Silhouette93 Yes you are right but still.. In a topological space you can use Neighborhoods which is equivalent to "open balls" in a metric space.

Am I right in saying that the use of open balls for a basis only works for metric topologies because there is no sense of distance to define the open balls on in non metric topologies?

What is the purpose of defining basis of a topology?

Just FYI, the Greek letter "τ" is pronounced as "tough", not "taw".

sir please take better the writing in the videos, thanks like good method at all

I would not recommend using union symbols and also denoting your open sets by the letter U. They look the same and it’s very confusing to distinguish between the two
