Fold a piece of paper in half 103 times, and its wider than the observable universe.
this is due to exponential growth; the increase in previous thickness is doubled each time you fold the piece of paper again. physically you could probably only fold a piece of paper about 7 - 8 times on your own.
Given a paper large enough—and enough energy—you can fold it as many times as you want. If you fold it 103 times, the thickness of your paper will be larger than the observable Universe; 93 billion light-years distance.
How can a 0.0039-inch-thick paper get to be as thick as the Universe?
The answer is simple: Exponential growth. The average paper thickness in 1/10th of a millimeter (0.0039 inches.) If you perfectly fold the paper in half, you will double its thickness.
Folding the paper in half a third time will get you about the thickness of a nail.
Seven folds will be about the thickness of a notebook of 128 pages.
10 folds and the paper will be about the width of a hand.
23 folds will get you to one kilometer—3,280 feet.
30 folds will get you to space. Your paper will be now 100 kilometers high.
Keep folding it. 42 folds will get you to the Moon. With 51 you will burn in the Sun.
Now fast forward to 81 folds and your paper will be 127,786 light-years, almost as thick as the Andromeda Galaxy, estimated at 141,000 light-years across.
90 folds will make your paper 130.8 million light-years across, bigger than the Virgo Supercluster, estimated at 110 million light-years. The Virgo Supercluster contains the Local Galactic Group—with Andromeda and our own Milky Way—and about 100 other galaxy groups.
And finally, at 103 folds, you will get outside of the observable Universe, which is estimated at 93 billion light-years in diameters.
The concept of intelligence has some rough backgrounds.
THE OBVIOUS RASICM
For example during the 19th century physical anthropologist Samuel George Morton believed that brain size was a measure of intelligence. He measured the sizes of hundreds of human skulls to assert that there was a difference between races.
He concluded that Europeans had the highest brain capacity, followed by Chinese, Southeast Asians, Polynesians, American Indians, and lastly African & Australian Aborigines.
Ofcourse now we look back at his work and realize it was the result of unconscious bias, reporting selected data, analytical errors & mismeasured skulls.
IQ tests stand for Intelligence Quotient Test. They are a standardized test that one cannot really study for. An IQ test measures a person’s general intellectual ability to understand ideas compared to the general population at the same developmental level.
How well we reason, distinguish relationships and solve problems and how well we process information, particularly our ability to store and retrieve it are also things IQ tests measure.
However, IQ tests fail to measure many things such as creativity, emotional sensitivity and social competence.
IQ tests are fundamentally flawed because they do not take into account the complex nature of the human intellect and its different components.
Furthermore, IQ tests are not good at predicting how well you are going to do in life. Just because someone scores high, it does not guarantee success.
Different people are good at different things. Someone might fail at one topic but excel at another.
As Albert Einstein said, "Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.”
These are 9 types of intelligence proposed by Howard Gardner.
Naturalist Intelligence (Nature Smart): human sensitivity to the natural word. Have you ever met someone who was really good with animals? Or who had a “green thumb”? Today they can be a chef or a botanist
Musical Intelligence (Music Smart): ability to recognize tone, rhythm, timbre, and pitch and more
Logical-Mathematical Intelligence (Number/Reasoning Smart) : ability to calculate, quantify, consider propositions and hypotheses, and carry out complete mathematical operations.
Existential Intelligence: sensitivity and capacity to tackle deep questions about human existence, such as the meaning of life, why do we die, and how did we get here.
Interpersonal Intelligence (People Smart): ability to understand and interact effectively with others.
Bodily-Kinestic Intelligence (Body Smart): manipulate objects and use a variety of physical skills. (athletes, dancers, surgeons)
Intrapersonal Intelligence (Self Smart): capacity to understand oneself and one’s thoughts and feelings, and to use such knowledge in planning and directioning one’s life
Spatial Intelligence (Picture Smart): those who have an amazing use of mental imagery and artistic skills
Linguistic Intelligence (Word Smart): ability to think in words and to use language to express and appreciate complex meanings.
Ofcourse these probably don’t capture everything in the wide range of smarts that we all have.
