Entry Two


Scientists at Europe's nuclear research centre have, for the first time, managed to trap
stable "anti-matter" particles.

In the above model, we can see an hydrogen atom and an anti-hydrogen atom.
in the anti-hydrogen atom, we can see a positron orbiting an anti-proton, as
opposed to the hydrogen atom, where we can observe an electron
orbiting a proton.

Most scientists agree that when the Big Bang occured, matter and anti-matter should 
have been produced in equal quantity. Up to now, almost everything we can observe
from the earth is made of matter rather than anti-matter.

This apparent imbalance is named "Baryon asymmetry.

Using the "Alpha experiment", scientists are able to hold antihydrogen particles for
as long as one tenth of a second, giving time for measurement.
So far, 38 antiatoms have been trapped for study.

Scientists are now closer to the truth about anti-matter and to the answer to:
Why so much matter and so few anti-matter?

Ghosts are visible manifestations of a deceased person or animal.

Ghosts have appeared in many different cultures.
In christian beliefs, orbs of light, a common form for ghosts,
represnt the devil disguised as an angel of light.

In chinese culture, ghosts are sometimes worshipped, but also feared.

In egyptian culture, ghosts represent the continued existence of the soul after
the death of a person. they also have the possibility of assisting or harming
the living. they also have the possibility of a second death.

In popular culture, ghosts haunt either a house, a cemetary, a family.
More often evil than good, these ghosts have appeared in many horror
movies and stories such as The Shining, Pacman, Super Mario, The Flying Dutchman, etc.

Examples of non-evil ghosts incluse Casper, The Three Stooges, The Ghosts in Harry potter, etc.

Most oftenly, ghosts only appear in pictures and just wander around the place.
Some may make noise to annoy the living, some may be harmful, some may warn those
to whom they appear.

Do you believe in ghosts?
Have you ever seen a ghost?
What do you think they want?
Are you afraid of them?
