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"

Mass and weight aren't the same as we know. Weight can vary depending on the gravitational field we find ourselves in. Mass is basically the measure of any matter's inertia i.e. how much force it will take to accelerate the mass and it remains the same despite what field it finds itself in.

A rudimentary understanding but in an atom the nucleus with the protons repel each other as we know. They can't 'fuse' together due to the repulsion. The neutrons have a 'neutral' charge and are bound in the atomic nucleus and become important later in the process. The electron has a negative charge.

In this model, the space between the nucleus and electrons is empty, it is pure vacuum. The atom can not get any smaller since the positively charged nuclei repels the bound electrons. The nucleus is 20,000 times smaller than the atom itself and the electrons in a variety of energy levels surrounding the nucleus.

In neutron star formation: picture a neutron to be the byproduct of an electron 'falling' into a proton and somehow combining with it due to some complex physics. That is why neutron has no charge (positive proton charge just cancels the equal but negative charge of the electron). Neutrons don't repel each other as they have zero electric charge. Thus the formation of a neutron star is when gravity forces all the electrons of the various atoms in the star into the protons making them all into neutrons hence the name.

All the electrons are now gone. The initial protons are converted to neutral neutrons and no longer repel each other. Newly formed neutrons plus the original atomic neutrons come together making essentially one big atomic nucleus made up of nothing but trillions of trillions of trillions of neutrons packed as closely as physically possible. All the empty space in the original atoms has gone in the matter. The result is a 20,000 times reduction of the size initially taken up by all of the atoms but retaining much of the same mass of the original matter. The density of the neutron star is now ten trillion times higher than ordinary matter, very a high mass density.

For example, ordinary iron (FE - atomic number 26) has a density of about 8000 kgs per cubic meter. The neutron star has a density of 2.4 × 10 to the power of 17 kg per metre cubed. That is a factor of 25 trillion times difference.

Well Shiiiiiiiiiit.....

You have that the wrong way round.

It has similar mass, but squeezed into a much, much, smaller volume. From a radius of maybe a million KM down to a couple of dozen or so. It's basically a star, but with all the empty space in the individual atoms removed, which goes to show just how much "nothing" there is in "something" Therefore the density is off the scale. A sugar cube sized piece of neutron star would weigh roughly the same as this whole planet.

The stone dolerite is a mafic intrusive rock. That is a rock formed by lava bursting towards the earth's surface but not quite making it to the surface before cooling. In the U.S it is called diabase.

When people in the Neolithic Stone Age started to mine copper and tin in what would later become the Bronze Age. They used dolerite to make the heads of hammers as it is an extremely hard rock.
(Used today for chippings in road construction).
When cutting rocks, copper saws were used and crushed granite dust (a felsic intrusive igneous rock formed again by lava) or dolerite dust was used as grit or like the teeth in the saw.

The climate changed in the late Neolithic and early Bronze Age in Europe and became wetter and colder. It was during this time that people began constructing stone circles. Dolerite or granite was used for the standing stones but dolerite seems to have been preferred over granite if it was available. Stone circles always had an entrance and facing the entrance as the person walked in would usually be a quartz stone.
Quartz is composed of silicon and oxygen. Silicon is used nowadays for chips in computers.
Some people say the granite and dolerite gives off energy and this may not be so far fetched as they can contain small amounts of uranium. The theory behind the quartz stone was that it amplified this energy towards whoever walked into the entrance.

But they called it "We haven't invented nails yet".

Nails were first used by the Egyptians around the time Newgrange was built, but the technology hadn't arrived here yet.

Nails were hand made up until around 1800 and were so valuable that they were often reused. The quickest way to get nails from an old, abandoned house was to simply burn it down and comb the ashes for them.

Not really particularly Irish - I think that is just for thicks to be honest

"The Irish equivalent of the verb "to be" has two present tenses, one (the present tense proper or "aimsir lhreach") for cases which are generally true or are true at the time of speaking and the other (the habitual present or "aimsir ghnlhreach") for repeated actions. Thus, "you are [now, or generally]" is tú, but "you are [repeatedly]" is bn tú. Both forms are used with the verbal noun (equivalent to the English present participle) to create compound tenses. This is similar to the distinction between ser and estar in Spanish.

The corresponding usage in English is frequently found in rural areas, especially Mayo/Sligo in the west of Ireland and Wexford in the south-east, Inner-City Dublin along with border areas of the North and Republic. In this form, the verb "to be" in English is similar to its use in Irish, with a "does be/do be" (or "bees", although less frequently) construction to indicate the continuous, or habitual, present:

"He does be working every day." Bn sg obair gach l
"They do be talking on their mobiles a lot." Bn siad ag caint go minic ar a bhfp
"He does be doing a lot of work at school." Bn sg damh go leor oibre ar scoil.
"It's him I do be thinking of." Is air a bhn mg smaoineamh.
This construction also surfaces in African American Vernacular English, as the famous habitual be."

Some pirate trivia that I just recently read.

Pirates doubled as mixologists. They created a drink that prevented certain diseases. Pirates borrowed the recipe for grog and made it legendary by adding lemon juice (it helped prevent scurvy) and sugar (it tasted good). Their's was a drink that packed a punch.

Not all pirates who wore eye patches had missing eyes. The patches helped them with night vision. By wearing an eye patch, the sea buccaneers could always keep one eye adjusted to night vision. Pirates spent a lot of time going from the bright light above deck to the darkness below deck, especially when they were raiding ships or defending their own. If he lifted his patch before going below deck, a pirate could instantly see even if there was only a little light.

Red flags on a pirate ship were really bad. The Jolly Roger flag that flew from pirate masts was terrifying but the most dreaded sea flag was red. A ship hoisting a red flag warned its enemies that no mercy would be given to a captured ship, everyone on board would be killed immediately.

Pirates practiced gay marriage as early as the 1600s.

Julius Caesar was once captured by pirates. In 75 BCE, pirates captured Julius Caesar but when they only asked for a ransom of 20 talents, Caesar laughed in their faces and told them he was worth at least 50. While he was held captive, Caesar serenaded the pirates with poetry. Once his ransom was paid, though, Caesar had the pirates crucified as punishment.

Pirate earrings also served as ear protection. Pirate ships were outfitted with numerous cannons. Blackbeard’s Queen Anne’s Revenge, had a whopping forty. Those cannons were vital during combat when a pirate ship might need to sink an enemy to prevent capture. Cannonballs were accompanied by a loud blast, though, and were known to deafen. Pirates would hang wads of wax from their earrings to prevent this sound damage. They popped the waxy contraptions into their ears like a makeshift earplug when firing cannons.

Thanks for that, very interesting.

On a slightly related note, September 19th is Talk Like A Pirate day.

I think this is an obscure and strange enough story to go in here.

Chris Kyle is basically America's most famous soldier.
"The Navy credits me with more kills as a sniper than any other American service member, past or present. I guess that's true. They go back and forth on what the number is. One week, it's 160, then it's way higher, then it's somewhere in between."

He published his bestselling autobiography, American Sniper, in 2012. His book was turned into a film staring Bradley Cooper, and directed by Clint Eastwood, it made over $547 million (highest grossing US film of 2014).

In his autobiography, he wrote about a fight that he got into at a "Navy SEAL'S bar" with another ex-military guy who was 'disrespecting' America, so he punched this guy in the face. In the book he only referred to the ex-military guy as 'Scruff Face'.
He then went on a media tour to promote his book, and named Jesse Ventura as 'Scruff Face'.

Jesse Ventura is a former military guy, wrestler, author, presenter and former Governor of Minnesota. He won the Governor race as a non Democrat or a Republican!

Here is Chris Kyle saying that it was Jesse Ventura who he assaulted.

Jesse Ventura claimed that "The event this man spoke of never happened."
He filed a defamation suit against Kyle in January 2012, which Ventura did after Kyle failed to agree on a settlement in which he would state that the incident never happened.

This video was published on February 2nd, 2012. He died February 2nd, 2013. Chris Kyle was murdered in an unrelated incident at a gun range, by a guy who he had brought to the gun range.

In May 2013, Ventura substituted Taya Kyle, as executor of Chris Kyle's estate, as the defendant, with his lawyers arguing that "it would be unjust to permit the estate to continue to profit from Kyle’s wrongful conduct and to leave Governor Ventura without redress for ongoing damage to his reputation."

On July 8, 2014, Ventura was awarded $1.8 million: $500,000 for defamation and $1,345,477.25 for unjust enrichment. Everything that Chris Kyle said about the bar fight was entirely made up.

Following the verdict, HarperCollins announced that it would pull the sub-chapter "Punching out Scruff Face" from all future editions of the book.

A higher court then decided to overrule the lower courts judgement.

So as it stands now, Jesse Ventura won the case, spent $1 million on his legal fees, but won't receive any compensation from Chris Kyle's estate.

He has said that he is refiling a lawsuit against the estate.

Here is Jesse Ventura talking about it.

It's a fairly strange story all things being told.

It's a system that has been in place for decades, and has failed in some isolated situations which is known as a "run on a bank".

^ that’s not quite right. Jimmy doesn’t have to deposit 1000. The bank just needs to have 200 in its own reserves/capital to create a loan of 1000. Since that loan is deposited somewhere it increases the money supply. It’s a deposit in the account of the loanee or, if he uses the loan to purchase something, in the account of the person he purchases it from.

It's called fractional reserve banking and it's beggars belief.
They must keep a percentage on reserve, (usually 20%) so Jimmy blogs goes into the bank with E1000 and puts it on deposit. The bank can then loan out 800, I go get a loan of this E800 and the bank I deposit it into can then loan out 720. So on so forth until you get to zero. The figures are nuts. Put a few zeros on that and you can see why the banking system is fcuked. They create money out of nothing.
I believe now that some banks don't even hold a percentage on reserve.. breaking the fractional banking system too.
