The secret of Roman concrete was lost, I'm not sure they've worked it out even now, but I'm pretty sure it would have been based on lime. The modern cement is known as Portland. I can't vouch for who invented it.Cement must be doubtful, after all the Romans are known to have used concrete.
Beat me to it.Ada Lovelace invented the computer? What's all that about??! Lovelace is known as the first programmer (and immortalised in the programming language Ada), as she collaborated with Babbage.
He supposedly demonstrated it before anyone else. But Baird's version of TV was so clumsy that it's debatable whether he invented TV as we know it.John Logie Baird did not invent colour TV.
I gave everyone a day.Beat me to it.
Sure, a mechanically scanned monochrome system – but not colour. How many times do I need to emphasise the word colour?He supposedly demonstrated it before anyone else.
The survey is credited to Netflix.Looks like the whole article has not been researched properly. No wonder it's credited to a Daily Mail reporter. Accuracy and the Daily Mail - hmm
Back when typesetting was a skill, there would have been a limited range and number of characters. This is still evident today when online versions of long-established rags use 'pc' instead of a % symbol which is naturally available on any journalist's keyboard.I agree things can be unclear. Newspapers (paper ones) have limited space and so the headline writers sometimes take liberties.

Well, I never knew that! I've seen plenty about early TV, but no mention of alternating filters. Heck, the refresh rate was low enough in mono, so I can't imagine persistence of vision working well enough for colour rendition!The history of colour TV in the UK | National Science and Media Museum

"Colour television was first demonstrated publicly by John Logie Baird on 3 July 1928"
DId you hear the one about the dyslexic Yorkshireman?And as for the cat flap, well...
I believe it was Ted Lowe who said "For those of you watching in Black and White, the pink is behind the green". It's not as daft as it sounds when the green ball is on its designated spot.the green ball was behind the brown
There was something lurking in the hidden depths of my memory that made me think Baird demonstrated colour TV. (Back in my school days I had an interest in TV history). I had to do a web search to confirm it.Well, I never knew that!
I never thought it was daft. It's perfectly reasonable to describe the position of the balls like that for b&w viewers - if you know where the green is.It's not as daft as it sounds when the green ball is on its designated spot.
In those days the viewers would (mostly) have known where the colours where spotted and it was only when a colour was knocked well away from its spot that extra info was useful.I never thought it was daft.

It was Robert William Thomson from Stonehaven in Aberdeenshire that invent it. He also invented the refillable fountain pen.thought it was Dunlop invented the pneumatic tyre - I may well be wrong though.
"intendified" Identified makes more sense!
Were not the on screen presenters painted green to give clearer pictures. A forerunner of the launch of colour on BBC2 using snooker so no longer having to tell viewers the green ball was behind the brown.
Quite often one valve (pcf80?) failed and we had to call out the repair person. Less than immediate start.TVs don't boot immediately now, let alone in the '60s when all te valves and the tube had to warm up!
