Not a googler but I don't think they are using it extensively for scientific computing internally. The devs seem to be pushing it more towards server and systems development.
IE The GC thread I linked in another comment [1] makes it pretty clear that they may actually break the ability to easily call existing scientific libraries (ie by handing a pointer to a go []float64 to cgo) in favor of better real-time guarantees.
