Lecturer: Professor David W. Ball Ph.D.

 

Matter is the raw material of the universe. Stars, planets, mountains, oceans, and atmospheres are all made of matter. So are plants and animals-including humans and every material thing we have ever produced. Amazingly, this immense variety is generated by a limited number of chemical elements that combine in simple, well-defined ways.

 

Consider carbon, a relatively common atom with many faces:

 

â?? Diamond: When one carbon atom bonds to four others in a cubic structure, repeated many times, the result is diamond, a form of pure carbon that is the hardest known mineral.

 

â?? Graphite: In a different geometric arrangement, carbon atoms bond in a flat lattice that is among the softest known substances, graphite, which is used in pencil leads and lubricants.

 

â?? Nanotubes: Loop a sheet of graphite, one atom thick, into a cylindrical shape and you get a carbon nanotube, a material 300 times stronger than steel with remarkable electrical properties.

 

â?? Life: You would not be reading this if carbon were not an atom of surprising versatility, able to combine with other elements to create the complex chemicals that are the basis of life.
