Elements

Everything around us contains material that was once part of a star. The cells in our bodies, the air we breathe, and materials that make up the planets in our solar system are all linked to the stars through chemical elements.

Hydrogen and helium are the two most abundant elements. They were made in the Big Bang more than 13 billion years ago. Others, like oxygen and iron, are created deep inside stars. Supernova explosions blast them into space and form even heavier elements, such as gold and uranium.

Everyday Elements

Chemical elements are the building blocks of everything. The Sun and stars, the silicon chips in our computers, and all the cells in our bodies are collections of elements.

Hydrogen is the lightest and most plentiful element. It has one proton, one electron, and an atomic number of 1. It was created in the Big Bang, along with helium. The other elements up to uranium (number 92) are made in stars.

Elements Made by People

When physicists smash smaller atoms together during experiments in nuclear accelerators and reactors, they create elements that have atomic numbers higher than 92. Neptunium, californium, and plutonium (which is used in spacecraft power supplies) are good examples of these elements. Scientists also study the tracks atomic particles make in bubble chambers during high-speed experiments (right).

Formation and Distribution

Big Bang

The nuclei of the three most basic and plentiful elements in the universe began forming during the first 100 seconds after the Big Bang.

Stars

Atomic reactions deep inside stars combine atoms to form many of the familiar elements that make up planets, stars, galaxies, and us.

Supernovae

The extremely high temperatures and pressures inside exploding stars help create the heaviest elements. Supernova explosions scatter them throughout space.

Humans

Our bodies contain more than two dozen elements. We are made of material that was created in stars.

Gases

Most elements are solids and liquids at room temperature. Eleven are gases.

Stars, People, and Atoms

Elements in Us

The human body is mostly hydrogen and oxygen, with traces of other elements (color coded to the elements table).

How Elements Reach Our Bodies

If you want to know where most elements originate, look at the night sky. Most of the stars and all the planets you see came from materials cooked up deep inside other stars. When those stars died, their elements were scattered into space in gas and dust clouds.

•A nebula is the graveyard of a star that exploded as a supernova. Material in the cloud may become new stars.

We, too, are part of the cosmic recycling process. It began billions of years ago inside an ancient star. The calcium in our bones, iron in our blood, and oxygen in our lungs were all created inside that long-dead star.

•Look at your hand. It is a piece of the universe. Its millions of skin cells are each made of elements from stars.

Elements are the building blocks of the universe. Atoms are the basic units of elements. Most atoms are made up of three types of particles: protons, neutrons, and electrons. Every structure in the cosmos is made of atoms from many different elements.

•Each droplet of carbon is a tenth of the width of a human hair and contains thousands of atoms.

Creation of Elements in Supernova Explosions

Thanks to stars and the elements they create, the universe renews itself. When stars die, their material gets scattered through space as the seeds for new generations of stars. The heaviest elements are created in huge stellar explosions like Supernova 1987a (left). Temperatures and pressures in these outbursts are so high that atoms fuse to make more complex elements, such as lead, gold, and uranium.

The Fingerprints of Elements

Light from celestial objects identifies the chemical elements they contain. Each element has a specific fingerprint, which we can see with a spectroscope. Helium and neon are made inside stars. Helium’s spectral fingerprint is simple, while neon has many more lines. Elements like krypton and mercury are created in supernova explosions.

The human body is mostly hydrogen and oxygen, with traces of other elements (color coded to the elements table).

How Elements Reach Our Bodies

If you want to know where most elements originate, look at the night sky. Most of the stars and all the planets you see came from materials cooked up deep inside other stars. When those stars died, their elements were scattered into space in gas and dust clouds.

•A nebula is the graveyard of a star that exploded as a supernova. Material in the cloud may become new stars.

We, too, are part of the cosmic recycling process. It began billions of years ago inside an ancient star. The calcium in our bones, iron in our blood, and oxygen in our lungs were all created inside that long-dead star.

•Look at your hand. It is a piece of the universe. Its millions of skin cells are each made of elements from stars.

Elements are the building blocks of the universe. Atoms are the basic units of elements. Most atoms are made up of three types of particles: protons, neutrons, and electrons. Every structure in the cosmos is made of atoms from many different elements.

•Each droplet of carbon is a tenth of the width of a human hair and contains thousands of atoms.

Creation of Elements in Supernova Explosions

Thanks to stars and the elements they create, the universe renews itself. When stars die, their material gets scattered through space as the seeds for new generations of stars. The heaviest elements are created in huge stellar explosions like Supernova 1987a (left). Temperatures and pressures in these outbursts are so high that atoms fuse to make more complex elements, such as lead, gold, and uranium.

The Fingerprints of Elements

Light from celestial objects identifies the chemical elements they contain. Each element has a specific fingerprint, which we can see with a spectroscope. Helium and neon are made inside stars. Helium’s spectral fingerprint is simple, while neon has many more lines. Elements like krypton and mercury are created in supernova explosions.

The rocket "Fairydust" is the logo of CCC events. On the picture you can see the 7 meter high rocket in the exhibition hall Leipzig.

Ai Weiwei / 艾未未 : Sunflower Seeds

Ai Weiwei / 艾未未 : Sunflower Seeds

Ai Weiwei 艾未未 Sunflower Seeds at the Tate Modern, London – part of the Unilever Series. 12th October 2010 to 2nd May 2011.

See also a related set of CGI / 3D Computer Generated Images based on the work.

The work is made up of 100 million porcelain ceramic sunflower seeds, with the characteristic dark stripes created by individually hand painting a glaze by skilled craft workers in workshops in the Chinese city of Jingdezhen / 景德镇, a region with a very long history of production of quality pottery.

The seeds are grey and white, but the combination of skylight and artificial lighting creates purple and green hues in the shadows.

Visitors could originally walk upon the "field of seeds", but health concerns over the small quantities of airborne ceramic / vitreous dust that might be generated by friction between the seeds resulted in the work being fenced off with a knee high wire rope, and continuous guarding.

Both the public and the artist were not very happy with this arrangement.

Ai Weiwei ("Ai" is the family name) needles away at the conflict that arises between China’s ferocious economic freedoms and growth, and the restrictions resulting from an authoritarian single party state. He has both been the artistic consultant on the Beijing National (Olympic) Stadium and also endured house arrest and international travel restrictions. On one occasion he was so badly assaulted by the police that he almost died, requiring surgery to attend to internal bleeding from a head injury.

All the same. All different. Sunflower seeds are a traditional chinese snack food. You can offer them to people.

都是一樣的。所有不同。葵花籽是傳統的中華名小吃食品。你可以給的種子作為禮物的人見面時。向他們展示友好。
