Science and Technology in this alternate timeline is mostly changed from both Nuclear War (WW3) and failed Bio-weapon that damaged human civilization more.
Science and Technology after Doomsday and Outbreak
Americas (sans remant of Brazil)
Since most of Electric technology is permanently disabled in almost parts around of the planet, Most communication technology is cause revival of "old" post delivery system by horse (Mostly North America).
A History Technology and Science after Doomsday and Outbreak
After the war most countries focused on the survival of mankind. As things began to improve, new technologies came into existence.
1964-1975: Restructuring (in remains of Brazil, Europan, (least several parts) Asian and Oceanian of remaining nations)
1975-1990: "Cyber Dark Ages"
While 2/5 parts of world as Restructuring due thanks of Soviet Union's famous electricians bring some it back in Europe (firstly), Places like North America, Latin America, Africa, New Zealand (eventally in early 1980s) is permentantly failed there due of Nuclear bombs or missles destory all electrity around former parts of United States. Its cause technology seemly reverted back for now into "Neo"-Medieval technology and Feudal government system was revived and tribal goverment system with primitivie technology came in 1970s as anarchy destoryed remaining Doomsday nations.
1995-1999: Priorities and Preparation
1999-2006: Second Dark Ages (least in British Isles and still stuck in unfixable parts of world)
2008-Ongoing: Technological revolution
Technological Revolution was triggered by Soviet Union, Japan, Germany and Australia was successed reviving all lost technology books within from Pre-Nuclear War/Outbreaks, More new scientists, electricians, inventors and etc. (that have related to science and technology).
And its cause birth of newer technologies like miltiary, communications, house life, daily life, industry, biotechnology, spaceflight and airflight are finally reprogress and move on from unstuck in early-mid 1960s into seemly late 1960s to beyond (currently in reach to early 1970s).
2009-Ongoing: Recommunication attempts to North America
France's goverment was rediscovered lost american continents as its fifths satellite communication take photographs around plant with white lights (mean presents areas have electricity) and some are planning is ether take there lost colonial island(s) (Saint Pierre and Miquelon) from unclaimed since WW3 happened.
