The First President of the APS (American Physical Society) was Henry A. Rowland. His presidential address, delivered at the second meeting of the Society on 28 October 1899, is remarkable. I consider it a must-read for all physicists and especially those young physicists who are still pursuing their studies.
Click below for PDF hosted at aip.org:One of the most important outstanding problems in astrophysics today concerns the “dark matter problem.” For about forty years now, it has been assumed that the observed dynamical behavior of spiral galaxy disks cannot be explained by canonical Newtonian physics without invoking ‘dark matter’ particles, which make up the majority of a spiral galaxy’s mass, yet are mysteriously invisible. This proves to have been a mistake; a definitive answer to the problem may be found here: < http://GravitySim.net >
