science係explain/predict 現象，maths只係講出黎的語言，唔係content. 
諗唔明點解Lindelof Covering Theorem點解啱
例如infinite covering{(1/n,1)}n=2 to inf cover (0,1)
點解會搵到finite subcovering cover (0,1)
定係我理解錯

有finite cover有咩出奇
條theorem句statement係乜

睇錯野，你呢個唔可能有finite cover架喎
Countable 喎
S is a subset of R^n, F is a open cover of S then there exists a countable subcover of F for S
係喎
個theorem 係 countable subcover ？
thank you
