As people here work in various jobs / professions they might know things from work or study no one here knows yet. this is what this topic is about.

what do you know that we have never heard of?

Eg: you don't need to be great at maths to be an architect

this is obvious to me but everyone says to me "i wanted to be an architect but i was bad at math,i can barely add"

You'd probably guess that volcanic lava is heated by pressure, but you may be surprised to know that it is substantially heated by two other major mechanisms:

1. Continuous cooling of the earth's core and mantle since the earth was formed about 4.6 billion years ago
2. Radioactive decay from naturally occurring materials such as plutonium and uranium

I found it hard to think that there would be a substantial affect from billions of years of cooling, nor enough radioactive material to cause heating. However, the vast majority of the thermal energy within the earth is from these means, with a tiny amount from the sun.

There is a rare mental illness called the Cotard delusion (or informally as Walking Dead Syndrome) in which the sufferer thinks they are dead.
It can happen due to some sort of brain damage such as an accident or a stroke.
There are successful drug treatments now, but people in the past with the syndrome have died of starvation through thinking that they don't need to eat because they are dead...

Did they try haunting people or places?

Tell me how

The term rain check is pretty widely used as a polite informal way to stay away from or cancel an engagement. I myself understood that its origins were directly weather related. As in, it was common to say something like "we'll check on the day, and if it is raining, we will cancel." This was only partially true.

Heard this morning that the true reason and origin of the phrase came from Baseball in the early 20th century. If a game was rained off or cancelled outright due to poor weather, fans were given a voucher to attend a future game. This voucher or rain check used the American spelling (check as opposed to cheque) and the term moved in to common usage. I think it is a good example of where something is misunderstood and yet the false understanding is as believable and accurate as the correct one.

Nuclear testing in Algeria driven northwards by winds like the Scirocco.

1950's is residue from early US and USSR tests as well as bombings in Japan.

All European wines show these traits. The levels are harmless.

I don't think that was the one (IIRC it was a Western, but I'll check tomorrow), it was filmed just beside the test area and nobody had been told about it, and half of the actors and crew died of cancer.

The nuclear experiments in the US that eventually caused cancer in John Wayne and a rake of other actors in that film they were shooting near there?

Either that or it was the four packets of cigarettes he smoked a day!!

The film you are referring to was called The Conqueror, where the Duke was playing none other than Genghis Khan! A bit of a crackpot casting choice, but the film made money but was savaged by critics.

It has made it into folklore because a fair number of the cast and crew (including the leading lady, director and support actors) died of cancer. Out of over 200 crew, I think maybe 50 or so (not exact numbers but thereabouts) died of cancer. But when you think about it, there is a fair chance that out of every four people you know, at least one will get cancer. Back in those days when medicine had not come as far as it has now, it would have been fatal in a lot of cases. Plus, lifestyles were different, everybody smoked as mentioned above. More than likely John Wayne's cancer came from the cigarettes.

With that said, there were areas that were in the direct line of those nuclear tests, and people in those areas most definitely got cancer due to radioactive material from the blasts. But that was in a different area to the shoot for The Conqueror. In fact, in the main fallout zones there were a lot of mormons living there. When they started presenting with increased rates of cancers and leukaemia at a rate nearly five times higher than the national average, alarm bells started ringing. They shun both alcohol and cigarettes for a start, rates of cancer, if anything, should have been lower than the national average.

It has often been said, but obviously never confirmed, than the US government picked areas with a high mormon population as there was a better chance of them not causing too much of a scene if things went awry.

The gauge used by 17th century gunners, to calculate elevation for range, was marked off in intervals of 7.5 degrees of arc, called 'points'; the lowest point, for zero elevation, was blank, so led to the term 'point blank range' for short range gunnery.

That’s true in some sense and it does still happy in poorer countries where communities still bake their own bread in the local bakery, essentially to cut down on fuel costs. But the main reason for cutting dough is to create weak spots so the bread will rise evenly.

Seriously one of those ultraviolet pens for detecting counterfeit notes will show you the dots on the back of the pages on most colour and laser copiers.

This is Lake Attabad in Pakistan, one of the newest naturally formed lakes on the planet. It was formed after a giant landslide on January 4th 2010, blocking the river Hunza. The river and meltwater from surrounding glaciers filled the valley behind the landslide and by June of that year it had peaked at over 100m deep.

It is now over 20 km long and holds about 100 times as much water as Lough Neagh.

It also blocked off the Karakorum Highway which links Pakistan and China, necessitating a $275,000,000 diversion which involved building 7 tunnels.

It has become a tourist attraction in its own right thanks to its glacial waters and stunning bright colours.

Pakistan has more glaciers than any other country outside the polar regions.
