The keyboard we most commonly use today is called the "qwerty" keyboard for obvious reasons, but did you ever wonder why the letters are in that order?
It's actually because the original keyboards would jam if letters that were next to each other were pressed in too rapid succession.
In 1874 Christopher Sholes, who developed the layout, was aiming to slow typists down by putting the most common letters in the most hard to reach places, and thus reduce jamming.
Although modern technology has no issue with jamming, the keyboard stuck and is still the one we use today!
In common use, the word noise means any unwanted sound. Noises have different volume levels, and logic can pretty much explain that the loudest the noise, the more “I want to rip my ears off” feeling will increase.
Ever wondered what’s the loudest noise that mankind has ever heard?
On July 1 of 1916, at the Battle of the Somme, a charge of 60,000 lbs. Of explosives was detonated creating a crater that was 300 feet across and 90 feet deep.
The explosion, which occurred in France, could be heard as far away as London and was the loudest man made sound in history at the time.
Apparently there has been a louder noise, but this is one that Europe will surely never forget.
The tree that the house resides in is 80 feet tall and over 12 feet long.
This tree comfortably holds an 11 floor, 8000 square foot, over 250,000 nail wonder that would put every eight year old's tree house to shame.
The house stands at 97 feet tall, which means that it is 17 feet taller than the tree it resides in.
The creator of the treehouse, Horrace Burgess, is 56 years old and has said that he put over $12,000 into the building of the structure.
Also, Burgess says that he is not done making his monument in the trees. He's not stopping at floor #11! Do you want to move into this treehouse? I know I do. Tell us what you think about the colossal cabana in the comments below!
Michael Vasey, professor of psychology at Ohio State University, found in his research that if you're afraid of spiders, you tend to perceive spiders as bigger than they really are. This may feed your fear, and make it difficult to overcome.
It has been found that spider phobia affects 1 in 6 males and about half of all females. Participants of the study were asked to estimate the size of the spiders after each encounter. Researchers found that participants who were most afraid of spiders, also estimated the tarantulas' sizes to be largest
It makes sense that the animals most evolutionarily close to us would exhibit early manifestations of higher social behavior. In this case, scientists have observed that some primates are surprisingly sensitive to others' problems. For example, chimpanzees can't swim. Despite this, some chimpanzees have drowned in zoo moats trying to save others from drowning.
More evidence: Scientists set up an experiment where rhesus monkeys could pull a chain to get food. If they pulled the chain, however it would shock one of the monkey's companions. The result? They starve themselves for several days.
Behaviorists say that human morality grew out of this primate sociality, with two extra levels of sophistication: humans have a much more rigorous enforcement of moral codes with rewards, punishment and reputation building. We also have a degree of judgment and reason, something that other animals haven't developed.
