Post Modern world 1945-now
Late modern world 1780-1945 (from French revolution)
Early modern world (the Renaissance) 1450-1780
The first, literally my history, and where I have obviously witnessed so much change - especially in the UK. The other periods I have come across more than earlier ones in my reading, and where perhaps so much happened to advance progress, but no essential expertise as to such.
So, as to the first:
Like, not even having a TV in the house (as a child); listening to the (valve) radio quite a lot (even having had a crystal set (with headphones) - and where a mouse made its home in the valve radio); having food rationing until 1954 (and hence obesity being very rare); where the (suburban) roads were relatively safe to play on (cars not so common - and my parents never having had one).
Where smog sometimes appeared (London); where religious differences didn't seem to be a problem, although with an influx of migrants, racist attitudes were common (toward blacks), and where even the N-word was seemingly acceptable in a Dylan song (but understandable because of the context); where I did a lot of cycling to explore around London and its environs; where caning at school was common (especially for me!); where a mangle was used to wring water out before hanging clothes to dry in the garden; where refrigerators were not so common (not in our house, as per washing machine); where the local library was well-used - as were the local cinemas (four close by); having one good friend at school whose parents did have a car and who were relatively well off (Father an inspector at Bow Street police station in London) - such that we often went for days out, or to TV audience shows together (Arthur Askey being one).
Where, as a family, we often went on day-trips to the seaside or various amusements (zoos, funfairs, etc. - Battersea being one favourite, and the Roy Rogers and Trigger Show being another): where I can remember visiting the 1951 Festival of Britain exhibition (Dome of Discovery and Skylon) but not much else (aged five); where I can remember being in the crowd to witness the coronation of Queen Elizabeth II (1953); at school we would use logarithm tables (then slide-rules at college); bought one of the earliest available computers (Amstrad 6128), which did actually have a disk drive and colour monitor (mid 1980s); used the earliest examples of the internet (with screeching modem connecting); until 1967/8 homosexuality was illegal but now all changed, and the atmosphere much better in my view; from some TV programmes, it appears that the relationships between kids and teachers is more relaxed, even if life overall might be more stressful for the kids - all the new technology for example; where equality for females in most spheres eventually became more normal - even if some way to go still; seeing the first hovercraft being tested at the Isle of Wight - whilst on holiday there. Etc.
I have posted this before - as to scientific and technological developments occurring during my life.
