Dear all
Yesterday night my daughter who is in class 6 called me and asked about the God particle. It was very difficult to explain to her as at that age the knowledge of particle physics is far off. This is excerpts from the mail that I sent her, from what i understand from the 4th July CERN announcement; Do read it out to your child if of the same age group:

Yesterday night my daughter who is in class 6 called me and asked about the God particle. It was very difficult to explain to her as at that age the knowledge of particle physics is far off. This is excerpts from the mail that I sent her, from what i understand from the 4th July CERN announcement; Do read it out to your child if of the same age group:
From studying physics you know that the 118 elements in
the periodic table like Hydrogen, Oxygen, Nitrogen, Hydrogen etc is made up of atoms which has a mass, and
hence weight, and it can move. These properties of atoms are measurable and
quantified and hence we believe that it exists even though we can’t see them
with our eyes. These small balls of one element say like oxygen can join or
form a bond with another element
like hydrogen and can change into a
different substance or a bigger ball
like water . This bigger ball of water we call as water molecule. Thus we have all
the elements in the universe joining with each other elements forming big balls
or molecules of many things that we see and use whether it is your table salt
or chalk powder.
However if we
start taking a molecule, say that of water, we know that it is made of the
bonding or mixing up of two atoms of hydrogen and one atom of oxygen. Now if we
want to break this bonding, we can mix water molecules with the molecule of, say, calcium carbonate
which is nothing but your chalk. These molecules react to each other and one of
the elements say hydrogen atom escapes out in its original gas form.
From the above we know that the materials and substances
that we see and use in our daily life are made up of molecules which are made
of a combination of many atoms of the elements. However, scientist by their
experiments have found and proved that the atoms can also be divided and inside
an atom there is another small ball called the nucleus (which has protons and neutrons. Protons are positively
charged and neutron have no charge)
which is surrounded by negatively
charged particles called electrons.
They also found that the nucleus can further be broken into protons and
neutrons. The components of an atom -
electrons, protons and neutrons are called as sub atomic particles. Scientists
also found that sub-atomic particles posses energy in them, and this energy
cannot be seen but experienced like the heat energy and electric energy. We know
that that the electricity which gives us light and makes our machines work are
coming from these subatomic particles.
So how does a particle like an electron or a proton give
energy? Scientists in particularly Albert Einstein found that the matter or mass
which is seen and experienced as a particle is created from a large amount of
energy. And by breaking these particles, the mass in it can be converted back
to energy. So they developed machines called accelerators which will shoot one
particle like a gun into another particle and break it into energy. This
reaction was termed as nuclear reaction. While doing such experiments, the
scientists found that while breaking the smaller particles of protons and
electrons, along with the formation of energy, there are many other still
smaller particles formed which they
named as quarks.
Quark is an elementary particle which matter is made of.
Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the
components of atomic nuclei. Due to a phenomenon known as color confinement,
quarks are never directly observed or found in isolation; they can only be
found within baryons or mesons.
Mesons are hadronic subatomic particles composed of one quark and one antiquark,
bound together by the strong interaction.
An Indian scientist called Satyendranath Bose found that
it is a mistake to presume that all such sub atomic particles have mass which
can be converted to energy, but there are some other type of particles which exists
as an energy field but is a cause for
providing a mass to other particles. He wrote about this to Einstein and he
agreed to this thought and those imaginary particles were called Bosons to honour Bose. Later a
scientist named Peter Higgs in 1954 found that among many bosons there is a
type of boson which is the most elementary particle existing in an energy state
which was named as Higgs field. Thus
the Boson- Higgs particle was considered
as the basic element which gave matter its mass from an energy state and hence
resulted in creation of the matter and hence the Universe. Later a person called Leon Lederman wrote a
book on Higgs Boson and named it God
Particle which became popular.
The European Organisation of Nuclear research called CERN
headquartered in Geneva in Switzerland announced on 4th July that
the bosons which was till now only theoretically known was discovered in the
accelerator .
The significance of the god particle was first postulated
by our old Rishis in the Sankhya philosophy. This philosophical thought
mentions about Prakriti (Mass/Universe ) and Purusha(Energy State/
Consciousness ) as the basis of the
universe. The Prakriti is according to them was formed from the Purusha
through a basic element called as thanmatra,
which we today discovered as Boson- Higgs Particle.
