Chaos Theory
Posted On : Aug / 02 / 2008
In
mathematics, chaos theory describes the behavior of
certain dynamical systems – that is, systems whose
state evolves with time – that may exhibit dynamics
that are highly sensitive to initial conditions
(popularly referred to as the butterfly effect). As
a result of this sensitivity, which manifests itself
as an exponential growth of perturbations in the
initial conditions, the behavior of chaotic systems
appears to be random. This happens even though these
systems are deterministic, meaning that their future
dynamics are fully defined by their initial
conditions, with no random elements involved. This
behavior is known as deterministic chaos, or simply
chaos.

The World's First Time Machine?
Posted On : Jul / 24 / 2008
Never
heard of "traversable wormholes?" Well, soon you
might start hearing about them, as the world's most
powerful particle accelerator becomes functional
this spring - unleashing forces, capable of
distorting not only space (just like gravity
distorts space around Earth), but also TIME. An
experiment nuclear scientists plan to carry out in
underground tunnels in Geneva in May could create a
rift in the fabric of the universe. The European
Organisation for Nuclear Research (CERN) hopes its
"atom-smashing" tests - which aim to recreate the
conditions in the first billionth of a second after
the "Big Bang'" created everything - will shed
invaluable light on the origins of the universe.
Large Hadron Collider
Posted On : Jul / 24 / 2008
The
Large Hadron Collider (LHC) is a particle
accelerator complex intended to collide opposing
beams of 7 TeV protons. Its main purpose is to
explore the validity and limitations of the standard
model, the current theoretical picture for particle
physics. This model is known to break down at a
certain high energy level. The LHC is being built by
the European Organization for Nuclear Research
(CERN), and lies under the Franco-Swiss border near
Geneva, Switzerland. The LHC will become the world's
largest and highest-energy particle accelerator. It
is funded and built in collaboration with over two
thousand physicists from thirty-four countries as
well as hundreds of universities and laboratories.
Archimedes

Archimedes
was a Greek mathematician, physicist, engineer,
inventor, and astronomer. Although few details of
his life are known, he is regarded as one of the
leading scientists in classical antiquity. Among his
advances in physics are the foundations of
hydrostatics, statics and the explanation of the
principle of the lever. He is credited with
designing innovative machines, including siege
engines and the screw pump that bears his name.
Modern experiments have tested claims that
Archimedes designed machines capable of lifting
attacking ships out of the water, and setting ships
on fire using an array of mirrors.
Magnetosynthesis

Mr.
Jackson's most recent research has yielded an
astounding theory; that movement is as important as
nourishment to human beings. He came to that
conclusion based on the behavior of magnetic
bacteria. He also believes these bacteria may be
responsible for cell division. "I think movement
through the earth's magnetic field is as important
as nutrition."
Biofuel
Posted On : Jun / 24 / 2008
Biofuel
(if cultivated, then also called agrofuel or
agrifuel) can be broadly defined as solid, liquid,
or gas fuel consisting of, or derived from recently
dead biological material, most commonly plants. This
distinguishes it from fossil fuel, which is derived
from long dead biological material. Biofuels are
used globally and biofuel industries are expanding
in Europe, Asia and the Americas. The most common
use for biofuels is as liquid fuels for automotive
transport. The use of renewable biofuels provides
increased independence from petroleum and enhances
energy security.[1]
Are We Missing a Dimension of Time?
Posted On : Jun / 16 / 2008
A
scientist has put forward the suggestion that there
are two dimensions of time, not the one that we are
all familiar with, and even proposed a way to test
his heretical idea next year. Time is no longer a
simple line from the past to the future, in a four
dimensional world consisting of three dimensions of
space and one of time. Instead, the physicist
envisages the passage of history as curves embedded
in a six dimensions, with four of space and two of
time. "There isn't just one dimension of time,"
Itzhak Bars of the University of Southern California
in Los Angeles tells New Scientist. "There are two.
One whole dimension of time and another of space
have until now gone entirely unnoticed by us."
Time is Running Out - Literally
Posted On : Jun / 16 / 2008
The
idea that time itself could cease to be in billions
of years - and everything will grind to a halt - has
been set out by Professor José Senovilla, Marc Mars
and Raül Vera of the University of the Basque
Country, Bilbao, and University of Salamanca, Spain.
The motivation for this radical end to time itself
is to provide an alternative explanation for "dark
energy" - the mysterious antigravitational force
that has been suggested to explain a cosmic
phenomenon that has baffled scientists.....
Radioactive Decay
Posted On : Jun / 15 / 2008
Radioactive
decay is the process in which an unstable atomic
nucleus loses energy by emitting radiation in the
form of particles or electromagnetic waves. This
decay, or loss of energy, results in an atom of one
type, called the parent nuclide transforming to an
atom of a different type, called the daughter
nuclide. For example: a carbon-14 atom (the
"parent") emits radiation and transforms to a
nitrogen-14 atom (the "daughter"). This is a random
process on the atomic level, in that it is
impossible to predict when a particular atom will
decay, but given a large number of similar atoms,
the decay rate, on average, is predictable.
Supernovae
Posted On : Jun / 15 / 2008
A
supernova is a stellar explosion. They are extremely
luminous and cause a burst of radiation that often
briefly outshines an entire galaxy before fading
from view over several weeks or months. During this
short interval, a supernova can radiate as much
energy as the Sun could emit over its life span. The
explosion expels much or all of a star's material at
a velocity of up to a tenth the speed of light,
driving a shock wave into the surrounding
interstellar medium. This shock wave sweeps up an
expanding shell of gas and dust called a supernova
remnant.
Fuels Gold - Ethanol

"All
this hoopla about corn ethanol is child's play
compared with the issue of biomass production in the
tropics," he says. "The issues with converting
pristine, important ecosystems into plantations will
dwarf the problems we have with corn ethanol in the
U.S. We're encroaching on the basic environmental
services of the planet, and that's a lot more scary
than polluting the Mississippi Basin and Gulf of
Mexico with nitrates." There's no such thing as a
totally benign, farm-grown energy source. "It's not
that simple," he says sadly. "It's anything but
simple."
Seawater : A Safe Blood Plasma Substitute?
Posted On : May / 08 / 2008
Diluted
ocean water is so similar to mammalian blood plasma
that it has been used successfully in animal tests
as a blood transfusion substitute. Historically, it
could also remineralize the body, normalize pH
levels, balance electrolytes and heal diseases. My
long-time fear of having a blood transfusion or
anything else injected directly into my unprotected
bloodstream has grown stronger over the years. Being
a health researcher, terrible visions of what could
go wrong haunt me, with good reason. I feel like the
meat inspector who becomes a vegetarian. I know
things that forever destroyed my innocent faith in
all things medical. I no longer worship in "The
Church of Modern Medicine" nor tithe to its
pseudo-gods voluntarily.
Rene Quintons Research - Ocean Plasma
Posted On : May / 08 / 2008
Have
you ever heard of René Quinton? Probably not. Yet
this man saved several thousands of children's lives
in France and in Egypt at the beginning of this
century by using a serum which now bears his name.
René Quinton "was the first person to discern and to
investigate the similarity between sea water and
mammalian lymph and blood plasma systems. He
endeavored to solve the mysteries of sea water and
its compatibility with living organisms by
proceeding to carry out several scientific
experiments in hospitals. The results he obtained
were dramatically unexpected, since several people
who were dying regained their vigor.
