It may be brave, but IMO Roger's assertion is totally justifiable.
As you state, mathematics is a language, a model, of the real world. It
may exist on its own in the real world (you can get a degree in the
subject), but like any other language, its use is as a representation or
reality, validated by experiment.
And when you put numbers (data) in a model, it can become more than a
generalisation, it can become highly specific - Apollo 11 on its journey
to the moon and back.
