Bits are a common and invasive piece of equipment used in equestrian sports. A bit should be carefully chosen to suit the individual horse according to the pressure points it is willing to accept. Bit pressure is poorly understood due to a lack of ac... Read More about A photographic methodology for analysing bit position under rein tension.

Fundamental limit to the use of effective medium theories in optics (2013)
