People show anger to others by their face, what they do with their body, not trying to understand or help other people's problems, and sometimes acts of aggression or force in public (e.g. punching a wall). Animals and humans might try to scare- by making loud sounds, trying to make their bodies look bigger, by showing their teeth, or by staring.
When we face a challenge, our response may be anger or fear. It may be difficult to decide whether to face the challenge, or walk away. In animal behaviour terms, we face the choice of a fight or flight response.
Being angry changes the human body by making the heart beat faster, increasing blood pressure (the pressure made by the blood at right angles of the walls of blood vessels) and increasing amounts of the hormones adrenaline and noradrenaline (chemicals which send messages to parts of the body to make changes).
Being angry makes the levels of the hormones adrenaline and noradrenaline in the body go up, although this does not last for very long. Adrenaline quickly makes the body ready to act when there is important trouble by increasing the supply of oxygen and glucose (needed to make energy) to the brain and muscles, while slowing less important things the body is doing, like digesting food.
Noradrenaline is released during stress. It goes to areas of the brain which control attention (how much you think or concentrate) and reactions. It is very important when the body chooses "fight-or-flight" (attacking or running away). Then it increases heart rate, takes glucose out of storage so it can be used, and increases blood flow to muscles.
Anger may be passive anger or aggressive anger.
These two types of anger have some characteristic symptoms:
Passive anger can be expressed in various ways. Basically it means being angry, but not facing the issue at hand.
The symptoms of aggressive anger are:
Light microscope
A light microscope works like a refracting telescope except that the object is very close to the objective lens. An object to be studied, for example a tiny organism so small it looks like just a dot, is put on a slide, which is usually a flat piece of glass. The clips on the microscope's flat stage hold the slide in place. The stage can be adjusted to add more light. It also moves to allow different layers of the object to be in focus. The user looks through the microscope eyepiece. A mirror at the bottom of the microscope reflects light rays up to the object through a hole in the stage. Objective lenses magnify the image which is made even larger when it is seen through the eyepiece lenses. Some light microscopes are actually digital cameras, made to photograph small things but having no eyepiece.
Many microscopes, often used in colleges and high schools, normally have a top magnification of 40x with the option of having 4x and 8x. This lets the microscope show basic cells and other items. Others can magnify hundreds of times, or thousands.
All modern optical microscopes designed for viewing samples by transmitted light share the same basic components of the light path, listed here in the order the light travels through them. Also almost all microscopes have the same 'structural' components:
These entries are numbered according to the image on the right.
Optical microscopes cannot show things that are smaller than light waves, because of the diffraction limit. Microscopes which can see smaller things include:
Rembrandt
Rembrandt Harmenszoon van Rijn (Leiden, 15 July 1606 – Amsterdam, 4 October 1669) was a famous Dutch painter and artist.
He is generally considered one of the greatest painters and printmakers in European art history, and the most important in Dutch history. His contributions to art came in a period that historians call the "Dutch Golden Age".
After his success as a young portrait painter, he had personal tragedy and financial hardships in his later years. Yet his etchings and paintings were popular throughout his lifetime, and his reputation as an artist remained high. For twenty years he taught nearly every important Dutch painter.
Rembrandt's greatest creative work is seen in his portraits of his contemporaries, self-portraits and illustrations of scenes from the Bible. His self-portraits are a unique biography, in which the artist surveyed himself without vanity and with the utmost sincerity.
He went to the University Leiden but he liked painting better so he became a painter. In 1631 he went to live in Amsterdam, because people there had heard of him and wanted him to paint their portraits. He married a woman called Saskia van Uylenberg in 1634. They had four children, but three of them died very young. Only their fourth child, Titus, who was born in 1641, survived into adulthood. Saskia died in 1642 soon after Titus's birth, probably from tuberculosis.
During Saskia's illness, a nurse was hired, who probably also became Rembrandt's lover. She later charged Rembrandt with breach of promise and was awarded 200 guilders a year. When Rembrandt learned she had pawned Saskia's jewellery, which Rembrandt had given her, he had her committed for twelve years to a poorhouse (a 'bridewell') at Gouda.
Rembrandt then lived with a young woman called Hendrickje Stoffels from Bredevoort who had been his maid. They had a daughter called Cornelia. Rembrandt died in Amsterdam on 4 October 1669.
Rembrandt painted many famous pictures. The portraits use light and dark colors; people sitting in the pictures are often shown in a calm or thoughtful appearance. He was such a good painter, that many of his pictures make people feel as if they are taking part in what is happening. Paintings by Rembrandt can be seen in art galleries all over the world.
Throughout his work Rembrandt used colour which darkens as it approaches the edge of the painting, and lighter towards the center. There is always a certain person, or event, or group of people that is near the center, and they are shown to be brighter than the rest of the picture. The dark backgrounds are painted to be very interesting and important. In most of his paintings, there are deep whites and blacks which shows contrast between different parts of the work.
Major movie studios
The Big Five are the United States's major movie production studios which also distribute their product. All of them have historic flagship production facilities near Hollywood.
With the possible exception of Disney, all five major studios are parts of much larger business enterprises, with their corporate headquarters offices far from Hollywood.
The group of major studios long numbered seven, but was reduced to six with the fading from importance of MGM in the 1980s. They became five when, on December 14, 2017, Disney announced its deal to buy Fox for $52.4 billion.

Culinary mustard
Culinary mustard is a condiment people use when making food. It comes from the seeds of the mustard plant.
Mustard is prepared by grinding the seeds of the Mustard plant, and mixing them with water or vinegar. Depending on which seeds are taken, and/or how much vinegar is added, the mustard may turn out hotter or less hot.
Most mustard is made available as a bottled condiment and can be spread on a slice of sandwich bread or squirted onto a hotdog along with ketchup, horseradish and other spices. It is often found in fast-food restaurants in the form of a small packet which the diner may open and squeeze into the dish of choice.
Condiment
A condiment is a prepared food that is put to other food, to make the food better or taste different. It usually is in the form of a sauce or a powder. Salt and pepper are examples of well-known condiments. Ketchup, mustard, relish, mayonnaise, horseradish, soy sauce and Worcestershire sauce are also well-known condiments.
