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"

Michell/Kingsbury tilting-pad fluid bearings, most likely. It's a form of hydrodynamic lubrication, which most modern-ish car engines use as well.

Steamers would mostly use tilting pad bearings, but the last one (LP section) is always usually an elliptical bearing

They numb the scalp to take care of that.

For epilepsy or brain surgery on tumours in critical areas of the brain that control speech, movement etc surgeons can perform awake brain surgery. They put you to sleep, open your skull up, then bring you around from the general anaesthetic while they are operating on you.

They'll map the function of the area of the brain, using electric probes to stimulate the brain and see what effect it has on you - asking you questions, checking your responses to make sure they're not hitting anything important while they're digging around in your head. Once they've built up a map of the areas they can safely remove they put you back under and complete the operation. Pretty amazing stuff.

Women can be fully awake during a C Section and people can be awake during dental surgery.

It's not THAT amazing...

A cow is usually standing during a c-section. Not always but vets prefer it.

Cow is still strung up on local anaesthetic though

Persil the washing powder for laundry got it's name from it's ingredients sodium perborate and sodium silicate.

It was developed by Henkel & Cie in Dusseldorf, Germany and launched on the 6th June 1907.

However in French, Persil means parsley. So in France it is branded and sold as "Le Chat".
It's sold under the name "Dixan" in Greece, Italy and Cyprus.
Then it's sold under the name "Wipp" in Spain and China.

It's sold as "Persil" mostly everywhere else around the world.

On August 27, 1883, Krakatoa, an uninhabited volcanic island near Indonesia, erupted spectacularly, expelling huge clouds of gas and ash, generating massive tsunamis, and killing more than 36,000 people

Starting at 5:30 a.m, Krakatoa experienced four massive explosions over the course of 4.5 hours. The blasts were so loud they could be heard as far away as Perth, Australia—3000 miles away. The force of the final blast at 10:02 a.m. was 10,000 times more powerful than the one unleashed by the atom bomb dropped on Hiroshima, and shockwaves generated by the eruption registered all over the world.

Apparently this is the loudest sound ever recorded, although not necessarily the loudest sound in history. It was measured at 180dB from a distance of 160km!

Yeah. The really crazy thing is it was heard at the time on Rodrigues island near Mauritius. 3,000 miles away! :eek:

Except that the decibel scale wasnot invented until 1923.

But one thing I do not know is - how did they measure sound levels in 1883 and what was the unit of measurement?

They used a Barograph, which was inveented in the mid 1700's. The sound wave was recorded several times over a few days, meaning that it travelled around the globe on a number of occasions.

You have to remember that it spread out like the ripple on a pond, except around a sphere, so on several occasions the sound wave actually crossed over itself.

From using calculations from other observatories, they were also able to pinpoint roughly where the explosion occured before any eyewitness reports confirmed it.

Persil is sold in France. It may be like tayto or bulmers where two companies have an identical brand name but the packaging looks the same as Persil sold in Ireland.

Dust from volcanoes can provoke beautiful fiery sunsets, and has inspired may artists over the years. Munch was inspired by the sunsets caused by the Krakatoa eruption to paint The Scream.

Becky Sharp was the first Technicolor movie. President Nixon's future wife appeared in it.

According to the current standard model of cosmology, the observable universe – containing all the billions of galaxies and trillions upon trillions of stars – is just one of an infinite number of universes existing side-by-side, like soap bubbles in a foam.

Because they are infinite, every possible history must have played out. But more than that, the number of possible histories is finite, because there have been a finite number of events with a finite number of outcomes. The number is huge, but it is finite.

There are an infinite number of "you" playing out different roles in different histories

Even more amazingly, we can work out how far away our nearest doppelganger is. It is, to put it mildly, a large distance: 10 to the power of 10 to the power of 28 meters. That number, in case you were wondering, is one followed by 10 billion billion billion zeros

Van Buren was the only president whose first language was not English. He grew up in a Dutch-speaking town in New York.

Wow. I almost didn't believe that so I googled them before posting. Amazing. Imagine what inspired them to dream up a world where one's physical shape was determined by a computer program. A wish fulfillment dream?
I hope they are happy in their new genders. They are geniuses and have contributed so much to intelligent sci fi.

That theory is not fully standard yet. It's not very provable for one.

The word Marmalade comes from Mary, Queen of Scots

When the queen was ill; the servants would bring her an orange preserve they made that seemed to help with her ailment. They would say “Marie est malade,” this was changed to Mariemalade, and later just pronounced Marmalade

Its a nice story but not true. The word marmalade predates Mary Queen of Scots.

James Caan a New York Jew was first put forward to play the lead Italian Mafia character Michael Corleone in the Godfather.

Coppala didn't like him because he didn't look like a wiseguy, he was pale and had light curly hair.

Instead he casted a dark featured real Italian. Al Pacino who was relatively unknown at the time. Caan was given the Santino role instead, which he played superbly in fairness.

Every film that John Cazale appeared in was nominated for the Best Film Oscar.

All his scenes in The Deer Hunter were shot first as he was dying of cancer at the time, he died before its release.
