Convulsive seizures are reported as [effects] of prefrontal lobotomy in 5 to 10 percent of all cases. Such seizures are ordinarily well controlled with the usual anti-convulsive drugs. Post-operative blunting of the personality, apathy, and irresponsibility are the rule rather than the exception. Other side effects include distractibility, childishness, facetiousness, lack of tact or discipline, and post-operative incontinence.
The Black Pearl (Scott O'Dell)
The Black Pearl is a book for teens by Scott O'Dell first published in 1967. It is about the son of a pearl dealer living in the Lower California peninsula. It won the Newbery Honor in 1968.
The story is about a Mexican teenager named Ramon Salazar who works with his father finding and selling pearls. One day, Ramon went diving in an underwater cave in search of pearls and found a pearl bigger than his fist. It was so shiny and big that he thought that it was called the Pearl of Heaven. The pearl was found in a lagoon that belonged to an Indian who warned Ramon that the pearl belonged to the Manta Diablo.
In 1977, Saul Swimmer directed the U.S.-Spanish co-production "The Black Pearl" aka "The stupid Negra".
Hot air balloon
A hot air balloon is a type of aircraft. It is lifted by heating the air inside the balloon, usually with fire. Hot air weighs less than the same volume of cold air (it is less dense), which means that hot air will rise up or float when there is cold air around it, just like a bubble of air in a pot of water. The greater the difference between the hot and the cold, the greater the difference in density, and the stronger the balloon will pull up. This means that balloons can carry more weight on a cold day, or if the air inside the balloon is very hot. At higher temperature, the air molecules move faster. This causes the molecules to spread out and therefore hot air is less dense than cooler air.
The hot air balloon is the oldest form of flying technology that can successfully carry people. The earliest use of hot air to make objects fly was made in Ancient China. Paper lanterns were sent into the air for signalling.
The first hot air balloon to carry a person was made by the Montgolfier brothers. On 19 September 1783, they demonstrated their invention for King Louis XVI and Queen Marie Antoinette at the French court in Paris. The passengers were a sheep, a duck and a rooster. They flew for 480 metres. The first flight carrying a person was on 15 October 1783. It carried Jacques-Etienne Montgolfier. The balloon was attached to the ground by a rope. The first "free" flight, without being attached to the ground, was a few weeks later, on 21 November 1783. It carried Marquis François d'Arlandes and Pilatre de Rozier.
The air is made up of molecules. When the air is cold, these molecules are closer together. When the air is hot, they move away from each other. So, in the same space, there are fewer molecules in hot air. Hot air is therefore lighter than cold air. This makes it rise and carry up the balloon when the air inside it is heated. The air is heated in the balloon with a burner, which uses bursts of fire to keep the air hot. The fire is fuelled by propane.
The heated air is kept inside the balloon by its fabric. This is called the "envelope". It is usually made of nylon.
The passengers and the pilot stand in the basket, which is attached to the balloon by ropes. The basket is usually made of wicker. Baskets can come in many sizes. It can have enough places for up to 36 people. It depends the size of the balloon to carry that much weight.
A hot air balloon festival is a type of air show. It is where ballooners display and fly their balloons together. During these events, they fly in the morning and in the evening if the conditions allow it. People can enjoy a balloon flight if they pay. There are many activities. Sometimes, the balloons are lit up against the night sky.
At these festivals, people can see different shapes of balloons. Usually, they are kind of round but they may have forms.
Gaius Caesar
Gaius Julius Caesar (20 BC–4 AD) was one of two brothers adopted by the first Roman emperor, Augustus. Both died in their early twenties, clearing the path for Tiberius. Gaius Caesar had achieved the rank of Consul before his death.
Biplane
A biplane is a fixed-wing aircraft that has two fixed wings. The lower wing is often attached to the body of the aircraft and the top wing is raised above. Most early airplanes were biplanes because they have a stronger structure than a monoplane. When engineers found how to makes strong monoplanes, biplanes became rare because they produce more drag.
Famous biplanes include the Polikarpov Po-2, Sopwith Camel, Avro Tutor, Antonov An-2, Beechcraft Staggerwing, Boeing Stearman, Bristol Bulldog, Curtiss JN-4, de Havilland Tiger Moth, Fairey Swordfish, Hawker Hart, Pitts Special and the Wright Flyer. The Stearman is particularly associated with stunt flying with wing-walkers.
White chocolate
White chocolate is a type of chocolate. White chocolate is made of cocoa butter, milk, and sugar. In the United States, white chocolate must be at least 20% cocoa butter, at least 14% total milk solids, at least 3.5% milk fat, and less than 55% sugar or other sweeteners.
In the European Union, there must be at least 20% cocoa butter, at least 14% total milk solids and at least 3.5% milk fat.
Sea plane
A seaplane is a fixed-wing aircraft that can take off and land on water.
Paraglider
A paraglider is a free-flying, foot-launched aircraft.
In mountain areas, pilots usually take off from great height to fly down to the valley. In flat areas, a winch is used to tow the paraglider to a height of up to 400 meters before it is released. It is also possible to soar on the coast in laminar sea breeze. Some more advanced pilots also launch from hot air balloons or helicopters.
Blank slate
"For the book see here"
Blank slate, or tabula rasa (which means the same thing) was a philosophical idea of John Locke. It had, like much of philosophy, a history which went as far back as Aristotle, but it was Locke who made it known to our modern world:
Humans, when born, are thought not have mental experience or knowledge, and that everything is learned after they grow. In particular, Locke thought all knowledge came from sense data, and the mind is empty at the beginning. By 'sense data' is meant the process of hearing, seeing, touching etc.
Locke's idea was immediately picked up by others:
Many have held similar views. The founder of behaviourism, John B. Watson (1878–1938):
Throughout the 20th century the influence of evolution and genetics ran against these liberal ideas. Ethology proved that much animal behaviour was inherited, instinctual, (innate and permanent). Konrad Lorenz argued that the aggression so obvious in the history of mankind was a playing out of behaviour which had evolutionary advantage in our past. The field of evolutionary psychology set out to examine the role played by evolution on our mental life. If humans share a common evolutionary history with the other animals, it is likely that we inherit mental traits from our evolution. The human ability to learn a language is inherited, and is of huge practical importance. Very important also (though less obvious) is the way that our unconscious mind helps us get through life. The apparatus which performs that mental activity is certainly inherited. These are some reasons why a number of recent publications have rejected Locke's idea.
Lined paper
Lined paper is paper with lines printed on it. The lines are never parallel to each other, uniformly spaced with a larger space at the top. The horizontal lines are meant to separate lines of hand-written text. Lined paper is thinner than other types of paper
