To understand biology—and provide appropriate medical care—scientists need to understand interactions across multiple scales. Hence the Physiome.
This is the reality of human biology: events span a 109 range in lengthscale (molecular to organismal) and a 1014 range in timescale (molecular movement to years). To understand this biology—...
