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"

Ten of Swords

Many thousands of stray dogs live in Moscow and its suburbs (believed to number well into the tens of thousands) and to survive many have learned to navigate the complex subway system there. Some live in the underground stations to avoid the cold weather in winter and others have been observed catching trains to and from different neighborhoods where they look for food before catching another train back after dark. Most go unnoticed on the trains as they hide under the seats.

In Mendeleyevskaya station there is even a statue of a feral dog that lived in the station. He was nicknamed Malchik (boy) by some of the local traders in the station who used to feed him and play with him. In 2001 a mentally ill woman brutally killed the dog with a kitchen knife which caused public outrage. Local artists created the sculpture called "Compassion" as a symbol of respect to all living creatures and a symbol of protest against inhuman treatment of stray animals. It sits in the station concourse.

Looks like they based the statue on the moment she plunged the knife in for the first time :eek::eek:

The United States has 3 rollercoasters that are taller than Florida. Britton Hill is only 101m tall.

The highest point in the Netherlands is surprisingly high, Mt Scenery at 887m. It is slightly cheating though, being in the Caribbean

The Moon is retreating from the Earth at a rate of about 1 inch a year .

If you could time travel back to the Jurassic period when Dinosaurs existed and looked up at the moon on a clear night it would appear 4 times larger in the sky than it does now due to it being closer to the Earth at that time in Earths history.

So presumably tides were a lot stronger then?

Would that be half the distance away, the tides would be 4 times greater?

And we're in a cool time in history where solar eclipses happen the way they do, where the moon just covers the sun. In the distant past they'd have lasted much longer with more totality, in times to come there will come a point where they'll only ever be partial.

Dinosaurs existed 66M years ago. 66M inches = 1676.4km
Tne earth is 384,400 km from the moon, so how did it appea 4 times the size when it was less than 0.5% closer than it was now?

I would also think rate has increased over time to what it is currently due to gravitational pull

Fourier

Brief point for the bit below, angular momentum is basically the 'hitting power' something has from rotating. You can increase it in three ways: being heavier, rotating faster or rotate at the same speed from further away.

The moon's retreat from the Earth is a complex topic. Roughly speaking by squeezing the oceans and the Earth's rock, the moon effectively puts a break on the Earth's rotation. The squeezing, like stretching and pressing putty, heats up the oceans and rock slightly and this heat is paid for by removing some of the energy from the Earth. This makes the Earth spin more slowly losing angular momentum. However the Earth-Moon system as a whole has to have the same total amount of angular momentum*, so to compensate for the Earth's loss the moon increases its orbital distance so as to be rotating from further away.

However how quickly the moon does this is really a function of how easily it can squeeze the oceans. At times when giant supercontinents like Pangaea were in the way it couldn't do so as easily, so the Earth loss less angular momentum to heat and the moon retreated more slowly. So the rate of the moon's recession is not a pure physics problem, you need detailed knowledge of paleogeography.

It wouldn't have been four times bigger in the sky in the time of the dinosaurs, but it would have been about 4.1 billion years ago. Around the emergence of life it would have been twice as big in the sky. By the time of the Cambrian explosion it would have looked pretty much the same as today in size.

*This is a law of physics ultimately resulting from the structure of spacetime

Ben Nevis at 1,345m is the Highest montain in the UK

Except it's not.

Mount Hope is 3,239m. But there's some question as to whether it's really in the UK so probably safer to say Mount Paget at 2,935m

Did a bee-keeper course recently.....they are fascinating creatures.

The queen is not the boss. She is a bee producing living factory . She mates for 1 day in her life and stores the sperm and uses it to fertilize an egg. Perhaps 100 thousand in course of her life.

Bees dont mind the cold. They can heat up the colony by vibrating. They can cool it down by standing by entrance and fanning their wings to bring cool air in. They keep colony temperature within a degree of 37.5 (human body temp).

Scout bees find good food sources, and fly back and tell the rest of the colony so they can go directly there (saves energy). They tell the colony direction & distance! The do a "wiggle dance" which is a figure of 8 routine and the centre of the 8 points in the direction of food. Distance? That involves walking in a circle, which means "near" (less than 500m). If there is no circle done after the wiggle dance it means food is far, bring a snack!

If you have a few hives, you cant let one get too strong or too weak. If one becomes too strong it will raid the weak one, killing all bees in it, and steal their honey...in less than a day! Why? Because its easier fly next door and get a years worth of honey instead of flying for miles, if you think you can get away with it!

Bees do see in colour. But its not colour as we know it. They have good high-contrast vision, and bee keepers often paint symbols on the hive. A different one on each box, eg 3 horizontal bars, triangle, daisy, circle, etc. When a bee leaves the hive, she does a quick fly around to see where home is so she can find right hive when she gets back.

Local honey is supposed to be good for allergies (its made from the flowers (pollen) you are allergic to). But all honey made in Ireland is "local". Thats because the plants in Donegal, are largely same as those in Kerry, and Wicklow. The local label applies to very large countries like USA where there is huge difference between plants in Texas, and Florida and Alaska etc.

Its a true commune. Ruled by collective decisions by hundreds of bees.

A bee's sting is barbed so as to stick or fix in its target. This will rip off half the bee's body as it moves away. So a bee dies in stinging.

A wasp can sting repeatedly.

There is an international beekeeping competition.

The Judges are circulating, appraising the candidates.

The Frenchman has 10,000 bees in four very stylish, contoured bee hives. “A joyful bee is a profitable bee” he says. The Judges nod their approval. Aesthetic.
Next, they look at the German’s 15,000 bees housed in seven well-constructed, efficient hives. “Zis is vented, moisture controlled, well organised and my Bees become everything they can be- achieving tremendous honey production” he says.
“Well done” admire the Judges.
Lastly the Judges approach the Kerry man’s entry. There is a single dilapidated, yellow, podgy, crooked looking little Hive. 20,000 bees are crammed in, bustling for room.
“Aren’t these bees a little short on space”? ask the Judges.

“Yerrah, fuck them” he says.

AP McCoy had his first ride – seventh-placed Nordic Touch on the Flat at now defunct Dublin track of Phoenix Park on this day (September 1st) in 1990. Pat Healy took two photos of the then unknown jockey with Jim Bolger and his dad Peader because, AP's dad said to the photographer "Will you take a picture of my son’s first ride? He might not get many more." AP's win record was 4,358 GB & IRE Jumps winners along with 9 Flat race wins.

In 1914 the cruise ship - the Empress of Ireland sank with a total loss of 1012 lives, just two years after the RMS Titanic disaster, and a year before the loss of the RMS Lusitania.

It took just 14 minutes for the St. Lawrence River to swallow the Canadian Pacific’s RMS Empress of Ireland in the pre-dawn of May 29, 1914.

Although there were enough lifeboats for all on board the sinking resulted in the deaths of more passengers, but less crew, than perished in the sinking of the Titanic in 1912.

Three months after the Empress of Ireland sank, the First World War broke out. The disaster is essentially forgotten.
