American inventor and educator Alexander Graham Bell develops the telephone by converting electrical impulses into sound. 

Alexander Graham Bell believed the photophone, not the telephone, was his greatest invention. His photophone carried the spoken voice by reflected sunbeams instead of wire, but did not find any practical application a century ago. Because light has 20,000 times shorter frequency than microwaves, it can carry 20,000 time more information. Only since the onset of ( plastic ) computers has this ability been needed. It would seem that Alex Bell was ahead of his time. 

The photoacoustic effect was first discovered by Alexander Graham Bell in the early 1880s [18], but it was not applied to Fourier transform infrared (FTIR) spectroscopy until a century later [19,20], Significant advantages of FTIR photoacoustic spectroscopy (PAS) include the following (1) Spectra may be... 

President Garfield was shot in 1881 and died two months later of an infection. Alexander Graham Bell tried to find the bullet with a metal detector that he had invented, but failed — probably due to the metal in the president s bed frame.

Avoid words like afflicted , crippled , and victim when referring to a person with a disability. Also, remember that people are more than their disabilities. Instead of saying that President Roosevelt suffered from asthma , Helen Keller was handicapped by blindness , Peter Stuyvesant was an amputee or Moses was afflicted with a speech impairment , do say Einstein has a learning disability , Napoleon had epilepsy , or Alexander Graham Bell was hard of hearing or Marlee Matlin is an actress who is deaf .

Alexander Graham Bell s first phone call to his assistant in the next room was made on March 10, 1876. By 1920, 35 percent of U.S. households had telephones. Household access is now nearly universal. The Federal Communications Commission (2003) reports 97.6 percent of U.S. households had a landline telephone in the year 2000 (see Fig. 3-4). 

Thomas Edison and Alexander Graham Bell became celebrities and secular prophets. In Germany, privileged young aristocrats took to dreaming of new machines the way earlier generations dreamed of the hunt. ... 

Have you an ambition to found a new science Why not measure a smell Can you measure a smell Can you measure the difference between one kind of smell and another Until you can measure their likenesses and their differences you can have no science of odor. Find out what odor is—weight, or a vibration, and therefore capable of being reflected. Odors are becoming more and more important in the world of scientific experiments and in medicine—and the need of more knowledge will bring more knowledge, as surely as the sun shines. (Alexander Graham Bell, in Scientific Monthly, vol. 25, No. 6 [December, 1927], p. 481)... 

Information Technology (IT) has been called a disruptive technology, not because it interferes with the traditional personal doctor/patient relationship, but because it will leave behind those who do not embrace it. The invention of the electrical speech machine by Alexander Graham Bell was a disruptive technology that revolutionized communication. Information ethnology helps standardize and speed up medical care so that more patients can be treated at reduced cost. IT extends the physician s brain by providing information at his or her fingertips.
