In no field have we witnessed a greater impact of emerging technologies than in that of distance learning. Correspondence courses using printed material and postal mail have been replaced by Web-based courses with the potential to make learning available to anyone, anywhere at anytime. This potential cannot be realized, however, unless two digital divides are eliminated. Some people are on the wrong side of the first “digital divide” between the technology “haves” and the technology “have-nots”. The benefits of technology are less available to those who are poor, who live in rural areas, who are members of minority racial or ethnic groups, and/or who have disabilities (Kaye, 2000; U.S. Department of Commerce, 1999). Lack of access to new technologies limits their options for taking and teaching technology-based courses. This is true for individuals with disabilities, even though the rapid development of assistive technology makes it possible for an individual with almost any type of disability to operate a computer (2003 Closing the Gap Resource Directory, 2003). Unfortunately, many people with disabilities still do not have access to these empowering tools, putting them on the “have not” side of the first digital divide.

We have become accustomed to differentiating between the scanning microscope and the conventional transmission microscope according to the resolving power which the two instruments offer. The conventional microscope is capable of a point resolution of a few angstroms and line resolutions of periodic objects of about 1Å. On the other hand, the scanning microscope, in its normal form, is not ordinarily capable of a point resolution better than 100Å. Upon examining reasons for the 100Å limitation, it becomes clear that this is based more on tradition than reason, and in particular, it is a condition imposed upon the microscope by adherence to thermal sources of electrons.
