"An approximate answer to the right problem is worth a good deal more  
than an exact answer to an approximate problem."  - J. W. Tukey


"I like working on applied and theoretical problems at the same time  
and one thing nice about statistics is that you can be useful in a  
wide variety of areas. So my current applications include  
biostatistics and also astrophysical applications. The surprising  
thing is that the methods used are similar in both areas." - Bradley
