Allotropes of carbon
Carbon is capable of forming many allotropes due to its valency. Well known forms of carbon include diamond and graphite. In recent decades many more allotropes and forms of carbon have been discovered and researched including ball shapes such as buckminsterfullerene and sheets such as graphene. Larger scale structures of carbon include nanotubes, nanobuds and nanoribbons. Other unusual forms of carbon exist at very high temperature or extreme pressures.

ALUMINUM
THE 13TH ELEMENT IN THE PERIODIC TABLE OF ELEMENTS
*WHAT IS ALUMINUM?
- Aluminum derives its name from alum. The Latin name for alum is 'alumen' meaning bitter salt.Note on Naming: Sir Humphry Davy proposed the name aluminum for the element, however, the name aluminium was adopted to conform with the "ium" ending of most elements. This spelling is in use in most countries.
Aluminium was also the spelling in the U.S. until 1925, when the American Chemical Society officially decided to use the name aluminum instead.
*WHO DISCOVERED ALUMINUM?
-Hans Christian Oersted
*FACTS ABOUT OERSTED
-Hans Christian Oersted launched a new epoch in science when he discovered that electricity and magnetism are linked.
He showed by experiment that an electric current flowing through a wire could move a nearby magnet.
The discovery of electromagnetism set the stage for the eventual development of our modern technology-based world.
Oersted also discovered the chemical compound piperine and achieved the first isolation of the element aluminum.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

6. ALuminum in our society
Aluminum is used for many things in today society

Engines of vehicle
7. Sources
The process of getting aluminum metal by the electrolysis of alumina dissolved in
cryolite was discovered in 1886 by Hall in the U.S. and at about the same time by
Heroult in France. Cryolite, a natural ore found in Greenland, is no longer widely
used in commercial production, but has been restore by an artificial mixture of
sodium, aluminum, and calcium fluorides.
Aluminum can now be produced from clay, but the process is not economically
feasible at present. Aluminum is the most abundant metal to be found in the earth's
crust (8.1%), but is never found free in nature. In addition to the minerals declared
above, it is also found in granite and in many other common minerals.
8. Compounds
Ordinarily, aluminum is trivalent. At elevated temperatures, however,
a few gaseous monovalent and bivalent compounds have been
prepared (AlCl, Al2O, AlO).
In aluminum the configuration of the three outer electrons is such
that in a few compounds (e.g., crystalline aluminum fluoride [AlF3]
and aluminum chloride [AlCl3]) the bare ion, Al3+, formed by loss of
these electrons, is known to occur.
The energy required to form the Al3+ ion, however, is very high;
and, in the majority of cases, it is energetically more favorable for the
aluminum atom to form covalent compounds by way of sp2
hybridization, as boron does.
The Al3+ ion can be stabilized by hydration, and the octahedral ion
[Al(H2O)6]3+ occurs both in aqueous solution and in several salts.
9. History
(L. alumen, alum) The ancient Greeks and Romans used alum as an astringent and as a mordant
in dyeing. In 1761 de Morveau proposed the name alumine for the base in alum, and Lavoisier, in
1787, thought this to be the oxide of a still undiscovered metal.
Wohler is generally credited with having isolated the metal in 1827, although an impure form was
prepared by Oersted two years earlier.
In 1807, Davy proposed the name alumium for the metal, undiscovered at that time, and later
agreed to change it to aluminum. Shortly thereafter, the name aluminium was adopted to
conform with the quot;iumquot; ending of most elements, and this spelling is now in use elsewhere in the
world.
Aluminium was also the accepted spelling in the U.S. until 1925, at which time the American
Chemical Society officially decided to use the name aluminum thereafter in their publications.
