Media mistakes

Cement must be doubtful, after all the Romans are known to have used concrete.
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.

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.

Issac Newton invented the telescope? I think not. He invented the reflecting telescope, the refracting telescope having been in use for decades (notably by Galileo to discover the moons of Jupiter, and IIRC Galileo died the year Newton was born).

John Logie Baird did not invent colour TV.

The problem is not so much that the article is wrong, but it leaves out detail which makes it a misrepresentation.

And as for the cat flap, well...

Beat me to it.

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.

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
 
I agree things can be unclear. Newspapers (paper ones) have limited space and so the headline writers sometimes take liberties.
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.
 
Sure, a mechanically scanned monochrome system – but not colour. How many times do I need to emphasise the word colour?

"Colour television was first demonstrated publicly by John Logie Baird on 3 July 1928"

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!
 
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.

DId you hear the one about the dyslexic Yorkshireman?
the green ball was behind the brown
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.
(I see the BBC have gone retro with the music, back to 1977 (or whenever it was).)

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.

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 believe this goes back to the days of the movies, where makeup worn by actors (and actresses) was done in weird colours to get suitable looking makeup on B&W film, which at the time was badly lacking in spectral response. It probably continued into monochrome TV times as well.

But then there was a the son of a work friend of my father. The lad was totally colour blind, and when NZ went to introduce colour TV, wanted to know why, because he already saw the pictures in full colour anyway.
 
Just seen a clip from the Call The Midwife xmas special, set in the (judging by the looks) early '60s. A woman turns the TV on and the picture & sound appear immediately. TVs don't boot immediately now, let alone in the '60s when all the valves and the tube had to warm up!

Not so much a mistake, but a deliberate annoyance by the BBC. A slide up message at the end of "Strike" telling you to press red for the next episode. :mad:
What if your TV isn't connected to the internet? I'm against screen junk so you can imagine how much this development p's me off!
