I bet you didnt know that

Cartouche

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"

This stone (in German it's called "Sonnenstein") even works if it's cloudy. There are 2 lightbeams which you can see inside the stone and the brightness of this 2 lightbeams is used to see where you need to travel to get to specific positions. You can use this stone even 40 minutes after the sun is not visible anymore.

If you haven't seen the awful remake of Total Recall then don't.

If you have then the shuttle thing that goes through the centre of the earth breaks a lot of physics. Ignore the fighting outside while travelling in air that's very hot and dense, the stupid one is that the shuttle would have to be travelling about three times escape velocity, as in it would keep going right out into outerspace.

Researchers Solve the Mystery of the Atacama ‘Alien’ Mummy (her skeleton is 6-8 inches long)

Nolan’s initial analysis suggested that Ata, as the remains are known, was indeed a human with an estimated bone age of six to eight years at the time of death. This latest study adds to the find, revealing that Ata was a girl of Chilean descent. Her small stature and abnormal proportions were likely the result of genetic mutations largely associated with human growth, such as mutations in genes associated with dwarfism and scoliosis.

As Ian Sample reports for The Guardian, these genetic mutations can also explain the apparently advanced age of her bones. Based on this latest analysis, Nolan and his team believe Ata was born preterm, and was either a stillborn or died shortly after birth.

As Nolan explains in the statement, the “dramatic phenotype could in fact be explained with a relatively short list of mutations in genes known previously to be associated with bone development.”

The specimen is not ancient, writes Gizmodo’s George Dvorsky, probably dating back around 40 years.

So to respond to this and some related info, it's a handy jumping point to explain atoms.

The Thomas Jefferson National Accelerator Facility managed to use electromagnetic fields to measure the pressure within a proton. Previously people thought you'd have to use gravitational fields to do this (gravity responds directly to pressure, electromagnetism doesn't), but the group found a way around this. (Any more detail is too much for a forum post)

Quantum Theory is broken into two main branches:
Quantum Mechanics, which deals with situations were particles are moving slowly and don't decay or combine

Quantum Field Theory, which basically deals with every situation. However it is very difficult to work with.

There's a quantum field theory to handle each of the three forces, the one for the strong nuclear force being called Quantum Chromodynamics (QCD for short). This handles everything to do with what goes on in atomic nuclei.

QCD predicts massive internal pressure inside a proton, which has been confirmed by this experiment. The pressure in a proton is over ten times that on a Neutron star. Or

1,000,000,000,000,000,000,000,000,000,000

times atmospheric pressure. That's in every proton in your body.

So now that we have confirmation of this, the best way to think of* a proton is basically a ball of paste that starts off fluid like near the center and gets more viscous the further from the center you go, until it becomes solid at a certain point (the edge of the proton). At the point where it becomes solid, the pressure within the paste is ten times that of a neutron star. There are also three knots in the fluid/places where the fluid is twisted at the center (we'd call them quarks). Neutrons are the same. The internal flow of the paste is incredibly complicated, a supercomputer can't fully manage it.

Or simpler, a proton is like a toffee ball with a molten toffee center. There are three swirls within the creamy center, these are the quarks. They're more patterns in the proton than things in and of themselves

In helium then you'd have two protons and two neutrons, being four "paste balls" like this. It's never really clear when one ends and another begins though as tubes of paste connect each of them (we see these tubes as pion particles).

Then sitting on top of this is an electrically charged fluid, much more smooth and fine than the paste within the proton (like oil versus toffee). This fluid is the two electrons. We tend to think of it as two particles because it tends to leave two small marks in equipment like a Geiger counter. As Arnold Neumaier, professor of physics in Vienna says:
He uses the more accurate term "electronic fluid".

Other atoms are then the same, just with more toffee balls and more electronic fluid on top of them.

Again all of this is with the proviso that Quantum Theory just says "this is a handy way to think of an atom", it doesn't say if an atom is really anything like this. All this fluid stuff is most likely just like the flashing lights from my boardgame analogy earlier. It's what we tend to see, but it could be just a shadow or aftereffect of the real thing.

Note: It's a myth that an atom is mostly empty space. Coming from pre-quantum physics. The electronic fluid fills the atom from the nucleus all the way out to the edge. It comes from measuring the size of stuff with a Geiger counter or similar, but that's just one way of measuring this stuff, again to quote Arnold Neumaier:

Brilliant synopsis Fourier.

Speaking of neutrons, they make the magic happen, so to speak and allow us to harness nuclear power. Before their discovery it was thought to be impossible to release the energy within an atom.

Lorelli!

In 1974, Holland had a great football team and were expected to win The World Cup.

Before the final against West Germany, it is believed that they were set up by the German newspaper Bild who apparently sent women over to the team's hotel pool and then ran the story "Cruyff, Sekt, nackte Madchen und ein kuhles Bad"(Cruyff, Champagne, naked girls and a cool bath), targeting the team's star player Johan Cruyff and he spent most of the day before the final in talks with his wife over the phone.

West Germany went on to win.

A new technique to measure (well to extrapolate) the pressure inside a proton has lead to an astronomically high measurement, actually in the region of an order of magnitude higher than the pressure inside a neutron star (the densest object known) or 10 to the 30 times standard atmospheric pressure.

International career. Whiteside broke Pelé's record as the youngest player to appear in a World Cup, when he debuted for Northern Ireland aged 17 years and 41 days at the 1982 World Cup in Spain.

pleas advice

just reading a bit about Northern Ireland at the World cup:

In the 1958 competition Northern Ireland became the least populous country to have qualified for the World Cup, a record that stood until Trinidad & Tobago qualified for the 2006 World Cup. [Record now held by Iceland] Northern Ireland remains, however, the least populous country to have qualified for more than one World Cup finals tournament, to win a World Cup finals match, to have scored at a World Cup finals, [Record now held by Iceland] and to have progressed from the first round of the World Cup finals.

World War II

In occupied Europe the Nazis attempted to jam broadcasts to the continent from the BBC and other allied stations. Along with increasing transmitter power and adding extra frequencies, attempts were made to counteract the jamming by dropping leaflets over cities instructing listeners to construct a directional loop aerial that would enable them to hear the stations through the jamming. In the Netherlands such aerials were nicknamed "moffenzeef" (English: "kraut sieve")

Here’s a bit of Cup trivia you may not know. In 1962, NASA launched a small, spherical communications satellite called Telstar that ended up altering the look of the balls used in the World Cup.

Telstar was the first active communications satellite and the first commercial payload in space. By sending television signals, telephone calls, and fax images from space, the 3-foot-long satellite kicked off a whole new era in telecommunications—and soccer ball design.

There’s a direct line between the distinctive black and white patterning of Telstar’s hull and solar panels and the Adidas ball used as the official ball of the 1970 World Cup in Mexico and the 1974 World Cup in West Germany. While earlier generations of soccer balls were brown and did not show up well on television

The black and white panels were chosen to provide contrast for black and white TV's

Telstar had an orbital period of a little over two and a half hours. So you could only use it when when it was overhead. And not for long

https://www.youtube.com/watch?v=mn6TNWVjZP0

The Tornados had an instrumental called Telstar. #1 in the USA charts.
For 1962 it was jaw dropping, thanks to the production by Joe Meek.

If there's one tip I could give you today it's watch BBC4 music documentaries.

Joe Meek genius, but went crazy towards the end. Murdered his landlady and then killed himself. The really sad bit is that the legal battle over the royalties was settled in his favour three weeks later.

While earlier generations of soccer balls were brown and did not show up well on television, the 1970 and 1974 balls featured the now iconic 32-panel design of alternating white hexagons and black pentagons, a pattern that closely resembled Telstar. Fittingly, that first ball was called Telstar Elast; the official ball in 2018, a nod to the 1970 ball, is called the Telstar 18.

More likely because you needed two fuel holes for quick access to keep the thing running for any length of time. Not quite a joke either. I knew someone who had the series three E-Type with the V12. You could actually watch the fuel gauge slowly but perceptively drop on tickover. :eek: That engine was a beautifully engineered petrol leak, with added noise.

I had an XJ12 many many moons ago in Canada, fabulous car for L'Autoroute but it's a good thing fuel was cheap there. I think it was 2*40 liter tanks in a 5.3l V12....didn't last very long.

Also dead handy that it came with a builtin radar detector when we bought it

Nothing whatsoever happened in British history between 3 and 13 September 1752. The British Calendar Act of 1751 proclaimed that in Britain (and Americn Colonies) Thursday 3 September 1752 should become Thursday 14 September 1752

In 1752 Britain decided to abandon the Julian calendar in favour of the Gregorian. By doing so, 3 September instantly became 14 September - and as a result, nothing whatsoever happened in British history between 3 and 13 September 1752.
