Mauna Kea is a volcano in Hawaii. It rises 4,205 m above sea level, compared to the Mount Everest rising 8850 meters up in the air this seems like peanuts. But the secret of Mauna Kea’s hight, is under water;
Measured from its base at the bottom of the Great Ocean, Mauna Kea is 10,203 meters high!

During pregnancy, learning and memory skills improve dramatically, say researchers, reversing the popular myth that it is a time of dumbing down. Key brain areas also alter in size; changes that can persist for decades. Far from transforming mothers into weakened emotional wrecks who lose car keys and drop in IQ, it turns out having children makes them cleverer. It’s just hard to spot thanks to all that lost sleep.
‘Many benefits seem to emerge from motherhood, as the maternal brain rises to the reproductive challenge,’ says Professor Craig Kinsley, of Richmond University, and Professor Kelly Lambert, of Randolph-Macon College, both in Virginia, writing in the latest Scientific American. ‘In other words, when the going gets tough, the brain gets going.’
Their paper reveals that the brain-boosting potential of parenthood includes enhanced sensory abilities just after childbirth, allowing women to recognise their infants by faint smells and sounds. It also reports that women who have children in their forties are four times more likely to survive to 100 than women who gave birth earlier. Pregnancy enhances women’s brains just when the memory decline of middle age normally kicks in, say researchers, leading to better mental health and longevity.
Underlying these changes are two key processes. The first involves the hormonal fluctuations of pregnancy, birth and lactation, which remodel the brain, increasing the size of neurons in some regions. Women become vigilant and alert - and the benefits appear to be long-lasting, say Kinsley and Lambert.
Secondly, rearing a child is so challenging it stimulates brain activity. Having a baby is ‘a revolution for the brain’, says Dr Michael Merzenich of the University of California in San Francisco. The brain creates cells that thrive the more they are used and the emotional, novel experiences of childraising provide the most stimulating use of all.

By the time he was eight he had taught himself eight languages (Latin, Greek, French, Russian, German, Hebrew, Turkish, and Armenian). He also invented another, which he called Vendergood.
Youngest student at Harvard
William James Sidis gained entrance to Harvard at eleven, and gave a lecture on four-dimensional bodies to the Harvard Mathematical Club his first year. He earned his Bachelor of Arts degree, cum laude, on June 18, 1914, at age 16.
Shortly after graduation, he told reporters that he wanted to live the perfect life, which to him meant living in seclusion. He granted an interview to a reporter from the Boston Herald, which published his vows to remain celibate and never to marry, and a statement that women did not appeal to him (however, he later developed a strong affection for a young woman named Martha Foley). He later enrolled at Harvard’s Graduate School of Arts and Sciences.

Coca-Cola is invented by John Pemberton in the late 19th century. It was originally intended as a medicine against fatigue and headaches. The idea to call it Coca-Cola came from his business partner Frank Robinson in 1885. The name is made up from the two ‘medical’ ingredients; extract of coca leaves and kola nuts.
Cocaine
How much cocaine there was exactly in the cola is hard to determine, but that is was in there is certain. Frederich Allen even thought it had to remain an ingredient of the cola, despite all the heavy critique;
“But neither could Candler take the simple step of eliminating the fluid extract of coca leaves from the formula. Candler believed that his product’s name had to be descriptive, and that he must have at least some by-product of the coca leaf in the syrup (along with some kola) to protect his right to the name Coca-Cola. Protecting the name was critical. Candler had no patent on the syrup itself. Anyone could make an imitation. But no one could put the label “Coca-Cola” on an imitation so long as Candler owned the name. The name was the thing of real value, and the registered trademark was its only safeguard. Coca leaves had to stay in the syrup.”
It was not before 1929 that Coca-Cola became cocaine free.
Lina Medina (born September 27, 1933 in Paurange in Peru) gave birth at the age of 5 years, 7 months an
d 21 days and is the youngest confirmed mother in medical history.
Lina’s parents brought her to the hospital because of her increasing abdominal size. They thought she had a tumor, but in the hospital it was quickly clear that she was pregnant. A month later, at May 14 1939, her son was born by a caesarean section necessitated by her small pelvis.
The surgery was performed by Dr. Lozada and Dr. Busalleu, with Dr. Colretta providing anaesthesia. Before the operation, Dr. Lozada had brought her to the hospital in Lima to check whether Lina was really pregnant or not.
The case of Lina is well registered by Dr. Edmundo Escomel in La Presse Medicale.
Her son weighed 2.7 kg (6 lb) at birth and was named Gerardo after her doctor. Gerardo was raised believing that Lina was his sister, but found out at the age of ten that she was his mother. He grew up healthy but died in 1979 at the age of 40 of a disease of the bone marrow.
Lina her menarche had occurred at 8 months of age, and she had had prominent breast development by the age of 4. By age 5 her figure displayed pelvic widening and advanced bone maturation.

Very often the town with the name
‘Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch‘
is mentioned as the longest of the world, but it only comes in third on the list of longest place names.
The second place is hold by New Zealand who have a name for a hill that consists of 92 letters:
Tetaumatawhakatangihangakoauaotamateaurehaeaturipukapihimaungahoronuku pokaiwhenuaakitanarahu.
This one is actually entered in the Guiness Book of Records and is said to mean:
“The place where Tamatea, the man with the big knees, who slid, climbed, and swallowed mountains, known as land eater, played his flute to his loved one.”
This is called the Mpemba effect after the student who discovered this phenomanon. The high school student Mpemba from Tanzania, Africa discovered in 1969 that hot water freezes faster than cold water while making icecream.
His teachers did not believe it was possible, and it took several years until university professors finally accepted his discovery.
It is unclear what the exact cause of this phenomenon is, but there are several factors that have influence on the mpemba effect:
A part of the water vaporizes which already cools down the remaining water and of course has the effect that there is less water left to be freezed.
Besides the following has to be taken into account such as the possibility that the hot water holds less dissolved gasses, there is a difference in convection currents when cooling down and of course the surroundings can have effect as well.

People with red hair feel more pain than people with blond or dark hair. It is scientificaly proven that people with red hair need about 20% more anaesthetic during operations than other patients.
The cells that produce skin and hair pigment have a dysfunctional melanocortin 1 receptor in people with red hair.
This dysfunction triggers the release of more of the hormone that stimulates these cells, but this hormone also stimulates a brain receptor related to pain sensitivity.
This causes people with red hair to be more sensetive to pain.
Poor redheads!

It hardly ever rains in the desert, but if it does it rains really heavy rains. The water flows then through valleys where no one expects it even to be possible that water is flowing there.
These water flows are very dangerous as they surprise the people who are there at that given moment. There is no time to escape from water flows like this and the people drown.
In 1995 more than 300 people drowned like this in only one weekend in the Sahara.

This means that they already knew the earth was round.
Eratosthenes used geometry to estimate the circumference of the Earth.
Eratosthenes measured the altitude of the noontime sun at Alexandria at its maximum on Jun 21st. On that date, the Sun is directly overhead at noontime at Syene, in southern Egypt (latitude = 23.5 degrees north).
The zenith distance is the angle from the zenith to the point where the Sun was at noon; it is also 90 degrees minus the altitude. At Syene, the zenith distance was 0 degrees; at Alexandria it was about 7 degrees.
He knew how far it was from Alexandria to Syene, so he used geometry and the difference in zenith angle to estimate the size of the Earth.
