V.A. Shiva Ayyadurai.
In 1978, a 14-year-old named V.A. Shiva Ayyadurai developed a computer program, which replicated the features of the interoffice, inter-organizational paper mail system.

He named his program “EMAIL”. Shiva filed an application for copyright in his program and in 1982 the United States Copyright Office issued a Certificate of Registration, No. TXu-111-775, to him on the program. 

In the summer of 1978, Shiva had been recruited for programming assignments at the University of Medicine and Dentistry of New Jersey (UMDNJ) in Newark, New Jersey. One of his supervisors, Dr. Leslie P. Michelson, recognized his abilities and challenged him to translate the conventional paper-based interoffice and inter-organizational communication system (i.e., paper-based mail and memoranda) to an electronic communication system.

2022-04-04 04:51:13 Is the earth's rotation slowing down?

Yes it is, due to a transfer of Earth's rotational momentum to the Moon's orbital momentum as tidal friction slows the Earth's rotation.

That increase in the Moon's speed is causing it to slowly recede from Earth(about 4 cm per year), increasing its orbital period and the length of a month as well.
