Timeline of Communications, Transport and Military Technology
This is a timeline that very briefly covers important events for the
development of communication technology. Because communications intrinsically
relate to mathematics, transport, politics and military history, many dates
relating to those subjects are included too. Also includes early Internet
development and computers and programming languages.
The information has been drawn from a variety of sources around the Internet
and has been summarized extremely heavily. Searching suitable keywords on
Wikipedia or Google will provide greater detail.

The base 60 system still remains in use for time measurements
and map coordinates (degrees, minutes and seconds).

The writing runs in a spiral from the centre outward, a configuration
next used by "Compact Disc" systems 3500 years later.

and adopting elements of Linear-A.

the Macedonian Phalanx commanded by Perseus of Macedon. Both sides had approx 40000
infantry and 4000 cavalry. The Roman infantry had larger shields, better armour
and short swords while the Greeks had long spears. Although the phalanx was able to
drive the legion back against the foothills of Mount Olocrus, they lost structure on
the uneven ground and Perseus was too cowardly to deliver the charging cavalry wedge
that was the hallmark of his ancestor Alexander's victories. This battle marks the
