Jellyfish donât have a brain either BUT:
âIt was once presumed that jellyfish can only manage the simplest forms of learning, including habituationâi.e., the ability to get used to a certain stimulation, such as a constant sound or constant touch. Now, we see that jellyfish have a much more refined ability to learn, and that they can actually learn from their mistakes. And in doing so, modify their behavior,â says Anders Garm, an associate professor at the University of Copenhagenâs Department of Biology.
The Great Polish Map of Scotland is a large (50 m x 40 m) three-dimensional, outdoor concrete scale model of Scotland, located in the grounds of the Barony Castle Hotel.
âA gift to the Scottish people for the hospitality the Scots had shown the Poles during the war years.â
Here are 40 useless facts that everyone should know. There will be NO quiz on these later:
- In 10 minutes, a hurricane releases more energy than all the worldâs nuclear weapons combined.
- On average, 100 people choke to death on ballpoint pens every year. (This never happened back when we used feather quills on parchment.)
- On average, people fear spiders more than they do death. (Especially that big hairy thing behind my dryer that pops out when I change loads. Yikes!)
- Thirty-five percent of the people who use personal ads or online apps for dating are already married. And, men are three times more likely to use them than women.
- Only one person in two billion will live to be 116 or older.
- Itâs possible to lead a cow upstairsâŠbut not downstairs. (Which explains why the phrase âYou can lead a cow upstairs âŠ.â never caught on like leading a horse to water.)
- Women blink nearly twice as much as men. (Research has shown that dumbfounded wives blink at five times their husbandsâ rate after he has done something idiotic.)
- The Main Library at Indiana University sinks over an inch every year because engineers failed to account for the weight of all the books that it would eventually hold. (In other news, thereâs probably no truth to the rumor that you can enroll in the IU School of Engineering for $1.99 per credit hour.)
- A crocodile cannot stick its tongue out. (This is only a problem for pre-teen crocs when their parents ask them to do chores.)
- Ping Pong balls can travel off the paddle at speeds up to 160 km/hr. Thatâs just under 100 mph.
- A dentist invented the electric chair. (I think he didnât have many repeat patients.)
- In ancient Egypt, priests plucked EVERY hair from their bodies, including their eyebrows and eyelashes. (Any modern woman that has attempted to pluck a manâs eyebrows only to hear him scream like a toddler finds this fact unbelievable.)
- TYPEWRITER is the longest word you can type using only the letters on one row of the keyboard. (And no ⊠QWERTYUIOP is not a word!)
- âGo.â is the shortest complete sentence in the English language. (However, scientists found that virtually every woman on the planet just has to give her significant other âThe Look,â and they donât even have to use the word, âgo.â Itâs pretty much understood.)
- Nutmeg is extremely poisonous if injected intravenously. (Be careful next time you visit Grandma during the holidays. Iâm just sayinââŠ.)
- Honey is the only natural food made without destroying any life. What about milk, you say?
- A cow has to eat grass to produce milk, and the grass is living. There you go âŠ
- A snail can sleep for three years.
- No word in the English language rhymes with âMONTH.â
- Cephalacaudal recapitulation is the reason our extremities develop faster than the rest of us. (Iâm not sure what this is, but Iâm ready to kick your butt in our next game of ScrabbleÂź, Grandma! Hey ⊠is that nutmeg I smell?)
- The most common name in the world is Mohammed.
- The cigarette lighter was invented before the match.
- Americans, on average, eat 18 acres of pizza every day. (Donât look at me ⊠I can only do a couple of slices these days.)
- The âpoundâ key on your keyboard (#) is called an octotroph. (Freak Millennials out by saying âOctotrophâ instead of âHashtagâ the next time youâre trying to be hip. Such as âOctotroph BlowingMyMind!â)
- The only domestic animal not mentioned in the Bible is the cat.
- The âdotâ over the letter âiâ is called a tittle. (Yep ⊠I had to read that twice to make sure it wasnât what I thought it was at first ⊠Lol)
- Spiral staircases in medieval castles run clockwise. This is because all knights used to be right-handed. When the intruding army would climb the stairs, they would not be able to use their right hand, which was holding the sword, because of the difficulties of climbing the stairs. Left-handed knights would have had no trouble, except left-handed people could never become knights because they were assumed to be descendants of the devil. (My ex-wife is left-handed. Octotroph IKnewThereWasSomethingEvilAboutHer)
- A catâs jaw cannot move sideways. (Probably why cats got left out of the Bible.)
- The slogan on New Hampshire license plates is âLive Free or Die.â Ironically, prisoners at the State Penitentiary in Concord make the stateâs license plates!
- Chinese Crested dogs can get acne. (Puppy Clearasil is probably big in China.)
- Hydrogen gas is the least dense substance in the world, at 0.08988g/cc.
- There is debate on what is the densest substance in the world. Some say itâs hydrogen solids at 70.6g/cc, while others say it is Osmium, with a density of 22.61 g/cm3. (I can confirm that the densest thing in the world is my brother-in-law, Wayne.)
- The house fly hums in the middle octave key of F. (No word on how lovely itsâ singing voice is, however.)
- Betelgeuse, a giant red star, has a diameter longer than Earthâs orbit around the sun. (Fun Fact: Say the red starâs name three times, and Michael Keaton will appear in your living room.)
- The longest name of a place still in use is a hill in New Zealand: Taumatawhakatangihangaoauauotameteaturipukakapikimaungahoronukupokaiwhenuakitanatahuâ(thatâs 92 letters. I counted so you wouldnât have to. Obviously, mail envelopes in NZ are freaking HUGE!)
- According to Einsteinâs Special Theory of Relativity, it is possible to go slower than light and faster than light, but it is impossible to go at the speed of light. Also, there is a particle called tachyon, which is supposed to go faster than light. This means if you fire a tachyon beam, it travels before you fire it. Octotroph BlowingMyMindAgain
- Hummingbirds are the only animals that can fly backward.
- If you yelled for eight years, seven months, and six days, you would have produced enough sound energy to heat one cup of coffee. (Hardly seems worth it. Unless itâs a Monday, of course!)
- If you passed gas consistently for six years and nine months, you would produce enough gas to create an atomic bombâs energy. (I ainât touching this one!!!)
- The human heart creates enough pressure when it pumps out to the body to squirt blood 30 feet. (So, basically, Monty Python and Quentin Tarantino got it right.)

Spiders that disguise themselves as poo
We have quite a lot in our garden.
African elephants are a highly social bunch with tonnes of different ways to communicate.
They greet each other by intertwining trunks and express strong emotions by trumpeting. They are even thought to send messages over large distances with ground-based vibrations, which could be detected through their feet.
Now researchers behind a new study in Nature Ecology and Evolution believe wild elephants may be able to communicate with other members of their group by using sounds akin to names.
In the wild, theyâre incredible to watch.
You havenât lived until youâve experienced an angry bull trumpet. The vibration reverberates right through you.
Lightweight in comparison to many stories, but for the rock scene and the 70âs was quite a common occurrence!
According to the Ah-Tah-Thi-Ki Museum in Clewiston, Florida, the Seminole tribe is the only Native American tribe that was never defeated by white men.
The research vessel RV Flip is the only vessel in the world capable of shifting from horizontal to vertical position in the middle of the ocean.
Flip is not a small ship, it is about 108 meters long and weighs 700 tons. Engineers designed it to be able to move to a vertical position with 90 degrees straight, so that the front of the ship at the top is 17 meters high (i.e. a 5-storey building high) while at the bottom is submerged 91 meters long, i.e. that most of the ship is submerged underwater.
This helps the shipâs stability and resistance to waves, the transformation process takes about 30 minutes, in which the seawater is pumped into huge tanks in the back of the ship, which makes it sink into the water to become the ship in a vertical position, and this ship is considered one of the most important ships in the field of scientific research of seas and oceans.
Well, that gives a whole new meaning to the phrase bottoms up 
Donât get me started on that there vesselâs name⊠
I wouldnât want to be on it when it was doing it though.
âThe deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.â
Letâs say 7 miles
Or 10.9km (so much less maths) 
Hardly anyone in the UK would be able to relate just how deep 10.9km is, but 35,876 feet is easily compared to Everests 29,000 feetâŠ
They have my sympathy.
Miles sound better. Itâs actually 6.794697 miles but I rounded it up to 7.
Yes Bruce, I suspected that there might be a chart or statistic lurking somewhere on the internet that would negate my postâŠI think imperial may die out with my generationâŠOld dogs and all thatâŠ
There is quite a lot of metric in UK. I regularly did so with the Doctors measurements. Also with electrical systems.
