There can be no question but that the great principles of freedom of conscience, separation of church and state and voluntarism in religion, so basic in American Protestantism and so essential to democracy, ultimately are derived from the Anabaptists of the Reformation period.

With these confident words, Harold S. Bender introduced the main theme of his presidential address at the fifty-fifth meeting of the American Society of Church History, held at Columbia University on 28 Dec. 1943. In the decades that followed, Bender's speech—which he titled.

Plotting defect locations in insulating SiC presents a challenge because the total number of locations on a wafer is so large. We scan the wafer with visible light at an appropriate resolution and sort out transmissions appropriate for the defects we are looking for. Under these conditions, we find that voids and micropipes reduce the pixel transmission to 0.3 to 0.5. Sorting for this transmission reduces the number of pixels of interest to a manageable number, especially with recent progress in growing lower defect SiC. Now a commercial plotting program can easily display defect locations within a circle representing the wafer boundary. We verify the defect locations by scanning electron microscope secondary electron images and scanning optical microscope visible-light images at several resolutions.

Type I or ionic comet tails on the average make an angle of a few degrees at the nucleus with the prolonged radius vector in the direction opposite to the comet’s orbital motion. This fact was explained by Biermann (1951) as the aberration angle caused by the comet’s motion in the outflowing solar wind plasma, and, as is well known, led to the discovery of the solar wind itself.
