The ha-index is a new revolutionary index to measure the impact of a researcher.

• It is computed by taking her (his) height in centimeters and substracting 100. For women, 12 is added to the obtained value.
  
• Degrees
  • An ha-index between 80 and 85 is considered to be excellent.
  • An ha-index higher than 85 is too good.
  • An ha-index lower than 70 needs to be improved.
• The main advantages of the ha-index over other indices:
  • very easy to compute
    
  • gives better estimates of a researchers impact than others
    
  • in a research group this parameter clearly indicates the visibility of the researcher. The higher your index the more you stand out of the crowd.
    
  • chinese research will have troubles to catch up
    
  • confuses american researchers not used to centimeters
