Contemporary researchers in the mathematical sciences enjoy countless advantages over their counterparts of a century ago. A vastly larger and better-funded community now has convenient access to the literature, and to communication channels that make global collaboration easy.

General conditions, too, overwhelmingly favor contemporary researchers. Rates of extreme poverty have plummeted. Life expectancies are longer by two decades. No mathematician or physicist today dies of tuberculosis, or of peritonitis following a ruptured appendix.

Perhaps partly as a result, IQ scores have risen over the past 100 years. Just from 1942 to 2008, average scores on those tests that best measure abstract pattern recognition ability -- the key requisite for mastering advanced mathematics -- have risen by a standard deviation.

Access to advanced education in the mathematical sciences has become much easier and more general over the last century. Today's graduates hoping to pursue a career in research have vastly more practical options than did their counterparts of a century ago.

Institutional support is also vast compared to a century ago. In the US alone, major research universities offering tenure to professors in the mathematical sciences have more than doubled in just the past 25 years. Conferences, summer schools, and prestigious prizes abound.

Over the decades, the number of PhDs granted in the mathematical sciences has steadily grown. In the US alone, nearly three times more PhDs in mathematics were granted between 1995-9 than between 1960-4. (In physics, the corresponding growth factor was just over two.)

The global community of researchers in the mathematical sciences has grown over the last century by more than an order of magnitude, and technologies and circumstances obviously favorable to its success have improved and spread spectacularly.

Yet it is impossible to argue that all these advantages enjoyed today by researchers in the mathematical sciences have led to equally spectacular improvements in the overall quality of their achievements. At best, it may be possible to argue that no steep decline has occurred.
