This is a fascinating article from New Scientist. The symbols we use to represent numbers are, mathematically speaking, arbitrary. Now there is a way to write numbers so that their areas equal their numerical values. The font, called FatFonts, could transform the art of data visualisation, allowing a single infographic to convey both a visual overview and exact values.

SPLAT!
Here is the answer to the exploding brain problem.
43% of 9 lb = 3.87 lb
1 kg is approx. 2.2 lb so woman's brain weighs 1.76 kg
If 1 kg of water is equivalent to 1000 cubic centimetres then the volume of blood is approx. 1760 cubic centimetres. If this is spread at a thickness of 1mm (ie. 0.1 cm) then the area covered would be 17591 square centimetres or 1.76 square metres.
In reality blood is thicker than water (ie denser) so less area would be covered.
