# Spike Lee

Spike Lee at the 2009 Tribeca Film Festival
**Spike Lee** (born March 20, 1957) is an American movie director, producer, screenwriter, and actor. He also teaches movie at New York University and Columbia University. Lee has acted in many of his own movies.

## Early life

Lee was born Shelton Jackson Lee in 1957 in Atlanta, Georgia. His mother was a teacher, and his father was a jazz musician. When Lee was very young, the family moved to live in Brooklyn, New York City. His mother gave him the nickname "Spike".

## Career

The first movie Lee directed was *She's Gotta Have It*. Lee directed the two music videos for Michael Jackson's single "They Don't Care About Us". In 2002 Lee won the Special Award at the BAFTAs.

Lee's movies *Do the Right Thing*, *Malcolm X*, *4 Little Girls*, and *She's Gotta Have It* were picked by the Library of Congress to be remembered forever in the National Film Registry for being "culturally, historically, or aesthetically significant".

# Mark of Cornwall

King Mark and La Belle Iseult by Edward Burne-Jones
**Mark of Cornwall** was a king of Cornwall and a character in the Arthurian Cycle of medieval literature. Specifically, Mark is the husband of Isolde, who upon falling in love with Tristan a tragic story that has been the subject of numerous literary versions from the Middle Ages to the present day.
# Bromine

A tube with bromine in it. At the bottom is bromine as a liquid and above it is bromine as a gas. The tube is sealed in an acrylic cube.
**Bromine** (Br) is a chemical element. Its atomic number (which is the number of protons in it) is 35, and its atomic weight is 80. It is part of the Group 7 elements (halogens) on the periodic table. It is diatomic, which means that two atoms are stuck together to make a molecule in any bromine sample.

## Properties

### Physical properties

Bromine is a red-brown liquid. Liquid elements are rare; only bromine and mercury are liquid at room temperature. It easily evaporates to make suffocating brown fumes. It has a bad smell. Its name means "stench of he-goats". It can become a metal at very high pressures.

It has two stable isotopes. They are 79Br and 81Br. There are about 29 other radioactive isotopes.

### Chemical properties

Bromine is quite reactive. Its reactivity is between chlorine, which is more reactive, and iodine, which is less reactive. It reacts with metals and nonmetals. Phosphorus reacts violently with bromine. Aluminum reacts in a similar way. It can bleach things like chlorine. It reacts better in the light. It dissolves a little in water. Hot water makes it disproportionate into hydrobromic acid and hypobromous acid. Bromine can form compounds with substances such as sodium to form sodium bromide.

### Chemical compounds

Bromine forms compounds in many oxidation states: –1, +1, +3, +5, and (sometimes) +7. –1 is the most common. It is found as bromide. Bromides are not reactive. They are colorless solids that dissolve in water easily. Covalent bromides can be liquids or gases. The other compounds are all strong oxidizing agents. Their chlorine cousins are more common. +1 has the hypobromites, which are unstable. +3 has the bromites. Bromine dioxide is the only common bromine compound found in the +4 oxidation state. +5 has the bromates, which are more common than all the other ones except the bromides. Bromates are strong oxidizing agents and are sometimes added to flour. +7 has the perbromates. Perbromates are very unstable.

* Potassium bromide
* Sodium bromate

## Occurrence

Bromine is found as bromide in the ocean and in brine pools. The Dead Sea has a lot of bromide in it. Bromine is not an important part of our body, unlike its relatives chlorine and iodine.

## Preparation

Bromine is made by bubbling chlorine gas through a solution of a bromide. The bromide is oxidized to bromine, while the chlorine is reduced to chloride.

## Uses

It is mainly used to make organobromine compounds, organic compounds with bromine in them. Organobromines are used to put out fires. They used to be added to gasoline. Some were used as pesticides. Some inorganic bromides were used as sedatives. Bromine can also be used as a disinfectant. Silver bromide is used in film.

## Safety

Bromine is toxic and corrosive to skin. Bromine gas is irritating when it is breathed in, too. Bromine can react violently with many things.
# Entomology

Part of a large beetle collection
**Entomology** is the science of insects. People who study insects are called entomologists. Insects have been studied since prehistoric times, but it was not until as early as the 16th century that insects were scientifically studied.

Some entomologists study how insects are related to each other. Others study how insects live and reproduce because we do not know very much about some kinds of insects. Other entomologists study ways to keep insects away from crops that people use for food. There are billions of unknown species throughout the world and taxonomists categorize the newly found.

Entomologists meet to talk about their study of insects and to share ideas, just as all scientists do.
