This question is now closed.

I once worked for a company
that published the Yellow pages (or the Hull version anyway, which was actually in colour). I once asked how they got the colours so vibrant given the background, to which I was told that the paper isn't yellow to start with, it's actually white paper and is printed yellow, leaving spaces for the coloured adverts, (known in the industry as red/blue/white knockout. Which is why the white especially, was so white and not some off-white slightly ivory colour.
However, the black text is printed straight on to the yellow background.

How do projectors, project black?
I was sat in a meeting with some pretty clever people when one of them (who was clearly bored by my presentation) asked the above questions. Despite repeated internet searches to find the solution I am still stumped. Projecting no light at all would just show the wall colour (even with the contrast of the surroundings).

Could someone clever explain/solve this as it's been doing my head in.

Evidence Based Medicine
And why it took us so long to get there.

Medicine, like so many other fields, used to do things in a certain way just because they'd always been done in that way. Take broken ribs. The conventional treatment used to be to strap up broken ribs in a tight bandage around the chest. This achieved the square-root of fuck-all except to make the patient even more uncomfortable. It wasn't until some curious doctor started to measure patient outcomes that they discovered the ribs would heal at exactly the same rate regardless of whether they were strapped up or not.

Then take the duodenal ulcer. Used to be amongst the most common causes of surgery. Sometimes the surgery worked, often it didn't - and the doctors didn't know why. It wasn't until two bright sparks in Australia realised that almost all patients with the condition were infected with a common bacteria - H. pylori - and a simple regime of antibiotics were enough to clear up the ulcer in most cases. This was also the reason that some patients who had other surgery got better. It wasn't the surgery - it was the antibiotics they were given during the surgery that cured them.

So, it's puzzled me for ages why medicine didn't adopt evidence based medicine earlier. For a lot of conditions doctors used to be no more than modern witch doctors. Shake this stick, drink this tea, don't drink that coffee - with absolutely no clue as to what cured some of the patients. Was it shaking the stick or drinking the tea?

It's a lot better now but we're still not there. Some doctors still prescribe based on what they've always prescribed regardless of any evidence that the remedy does any good.

"But some patients get better on this regime" cry the doctors

Yes. But people have a tendency to get better on their own for a huge number of conditions.

Evidence based medicine. You know it makes sense. Homoeopaths, osteopaths and other snake-oil salesmen, take note.

Cheers

I hope I can explain this. I want someone who's faaaar less lazy than I am to work out what pages, ie, at what points in time, do you get the good answers, or better stories, as evidenced by being chosen for the Newsletter. I reckon that the the more keen posters will post good stories early, but who knows. Maybe it takes a few days, ie pages, for people to work out their ever-so-thriling tales.

Registration plates.
Why are the registration plates on cars in the UK black-on-white at the front and black-on-yellow at the back?

There must be a really good reason, because that's the convention that the French adopted when they ditched white-on-black plates a few years ago. (I think they're moving to black-on-white for both now, so there's a secondary question about why that is better yet, and why the UK doesn't do likewise.)

Landing lights
Why are you told to raise the blinds as aeroplanes come in to land? And why do they switch the lights off?

I once asked an air stewardess this, and she didn't know; her best guess was that it meant that your eyes would adjust to the light at the destination. I rejected this account on the grounds that it was palpably nonsense.

But I remain perplexed.

The moon mystery
I happened to find myself at Milton Keynes train station early one morning. I was waiting for the train to arrive in the bridge area (above the tracks) if anyone is familiar with the station.

So, I'm staring out of one of those little round windows at the moon. Perfect full moon and quite large (optical illusion when it's near the horizon or some such)

Anyhoo was just about to leave when all of a sudden the moon moved across the sky by tens of thousands of miles and turned blood red at the same time.

A sign of the apocalypse!!!? Was really shocking to behold such an event. Did the solar system just get a whack.

A less rational person than I would have ran for the hills (or nearest bunker or called the police and newspapers..

However it did take a tad bit too long for me to work out I had actually been staring at the reflection of the train signals.. doh!

Has anyone actually watched the Ocean Finance TV channel?

One that is bugging me after watching ‘Motorway Cops’:

Why is it, when the police want to stop a vehicle using the ‘stinger’ do they sit on the side of the road with their lights flashing then wonder why the criminal just drives onto the kerb. Surely it would be better to park their car around a corner and remain hidden.

As the stale aroma of a fart drifting through the room caused her nose to wrinkle in disgust
she sharply asked 'Was that YOU?'

'No!' I lied. However she insisted that as the one who denied it, I must have supplied it. By way of counter-accusation I pointed out that as the one who smelt it, she must have dealt it. TOUCHE!

I think I see the problem
Years ago I worked for a company supplying industrial process control equipment. It was all run by DEC PDP computers (I said it was years ago) which were floor-standing, cupboard-sized minicomputers.

One day we got a call from a customer who couldn't get their system started. After running through all our checks, it seemed that it must be a hardware problem so we contacted DEC to get one of their engineers to go and have a look.

A couple of hours later we got a call from the DEC engineer. In the original phone call, which lasted over an hour, at no point did the customer think it was necessary to mention that the computer room was currently six inches deep in water, due to a burst pipe...

Ace Mechanic, me.....
In the early 90s I was working in a particularly shite job in London, a 2 hr commute from home in East Sussex. My wife worked near to home, but had to drop our toddler son off at the childminders on her way to work. Several days in a row, she would drive the 10 miles in our ancient Volvo 360 to the childminders, drop the sprog, and return to the car only to find that it refused to start no matter what.

Twice, and because I needed little excuse to bail out of work, I left work in London (having only just arrived) to come and rescue the car. I would arrive at the car and it would start first time.

Staring under the bonnet, I realised that that when the engine got warm the radiator coolant would rise in the expansion bottle bolted to the inner wing. That bottle was cracked, and the water would soak the wiring that ran beneath it, causing it to not start once stopped. Leave it a couple of hours (the time it took me to get back from London) and the wiring had sufficiently dried to let it start again. £5 for a replacement from a scrappy, everyone's happy, except me... I had to go back to work.
