Maths is effective when it delivers simple, compact expressions that we can apply with regularity to many situations. It is ineffective when it fails to deliver that elegant compactness.

To summarize, it works well when it works well; it doesn't work well when it doesn't work well.

Global warming is a good example of when it doesn't work well since the previous collected data does not follow a pattern.

We can not predict weather long term but we can predict the time of sunrise and sunset.
