Water
is refreshing, hydrating, and invaluable to your survival. But clean
water remains a precious and often scarce commodity – there are nearly
800 million people who still don’t have regular access to it. Why is
that? And how can you tell whether the water you have access to —
whether from a tap or otherwise — is drinkable? Mia Nacamulli examines
water contamination and treatment.

Eighty-five
percent of the matter in our universe is dark matter. We don’t know
what dark matter is made of, and we’ve yet to directly observe it, but
scientists theorize that we may actually be able to create it in the
Large Hadron Collider, the most powerful particle collider in the world.
So how would that work? CERN scientist Rolf Landua explains how to
discover a new particle.

Observations
at far- and mid-infrared wavelengths provide a wealth of information
about the molecular inventory of interstellar gas clouds. Because of the
different chemical pathways responsible for their formation and
destruction, different molecules probe specific aspects of the
interstellar environment. Carefully interpreted, they provide unique
information about the molecular fraction, the UV radiation field, the
dissipation of energy within the turbulent ISM, and the cosmic-ray
density in the Galaxy. This talk will include a general overview of
astrochemical probes of the interstellar medium, along with new
estimates of a key parameter in astrochemical models: the cosmic-ray
ionization rate.

New Space Documentary 2017.

The
Universe is all of time and space and its contents. It includes
planets, moons, minor planets, stars, galaxies, the contents of
intergalactic space, and all matter and energy. The size of the entire
Universe is unknown.The earliest scientific models of the Universe were
developed by ancient Greek and Indian philosophers and were geocentric,
placing Earth at the center of the Universe.Over the centuries, more
precise astronomical observations led Nicolaus Copernicus (1473–1543) to
develop the heliocentric model with the Sun at the center of the Solar
System. In developing the law of universal gravitation, Sir Isaac Newton
(NS: 1643–1727) built upon Copernicus's work as well as observations by
Tycho Brahe (1546–1601) and Johannes Kepler's (1571–1630) laws of
planetary motion.Further observational improvements led to the
realization that our Solar System is located in the Milky Way galaxy,
which is one of many galaxies in the Universe. It is assumed that
galaxies are distributed uniformly and the same in all directions,
meaning that the Universe has neither an edge nor a center. Discoveries
in the early 20th century have suggested that the Universe had a
beginning and that it is expanding at an increasing rate.The majority of
mass in the Universe appears to exist in an unknown form called dark
matter.The Big Bang theory is the prevailing cosmological description of
the development of the Universe. Under this theory, space and time
emerged together 13.799±0.021 billion years ago with a fixed amount of
energy and matter that has become less dense as the Universe has
expanded. After the initial expansion, the Universe cooled, allowing the
first subatomic particles to form and then simple atoms. Giant clouds
later merged through gravity to form galaxies, stars, and everything
else seen today.There are many competing hypotheses about the ultimate
fate of the Universe and about what, if anything, preceded the Big Bang,
while other physicists and philosophers refuse to speculate, doubting
that information about prior states will ever be accessible. Some
physicists have suggested various multiverse hypotheses, in which the
Universe might be one among many universes that likewise exist.The
Universe can be defined as everything that exists, everything that has
existed, and everything that will exist.According to our current
understanding, the Universe consists of spacetime, forms of energy
(including electromagnetic radiation and matter), and the physical laws
that relate them. The Universe encompasses all of life, all of history,
and some philosophers and scientists suggest that it even encompasses
ideas such as mathematics and logic. The word universe derives from the
Old French word univers, which in turn derives from the Latin word
universum.The Latin word was used by Cicero and later Latin authors in
many of the same senses as the modern English word is used.A term for
"universe" among the ancient Greek philosophers from Pythagoras onwards
was τὸ πᾶν tò pân ("the all"), defined as all matter and all space, and
τὸ ὅλον tò hólon ("all things"), which did not necessarily include the
void.Another synonym was ὁ κόσμος ho kósmos (meaning the world, the
cosmos).Synonyms are also found in Latin authors (totum, mundus, natura)
and survive in modern languages, e.g., the German words Das All,
Weltall, and Natur for Universe. The same synonyms are found in English,
such as everything (as in the theory of everything), the cosmos (as in
cosmology), the world (as in the many-worlds interpretation), and nature
(as in natural laws or natural philosophy).

Universe | Beyond the Big Bang

       



Universe | Beyond the Big Bang

Δημοσιεύτηκε στις 10 Αυγ 2017

The
Big Bang theory is the prevailing cosmological model for the universe
from the earliest known periods through its subsequent large-scale
evolution. The model describes how the universe expanded from a very
high density and high-temperature state and offers a comprehensive
explanation for a broad range of phenomena, including the abundance of
light elements, the cosmic microwave background (CMB), large scale
structure and Hubble's Law. If the known laws of physics are
extrapolated to the highest density regime, the result is a singularity
which is typically associated with the Big Bang. Detailed measurements
of the expansion rate of the universe place this moment at approximately
13.8 billion years ago, which is thus considered the age of the
universe. After the initial expansion, the universe cooled sufficiently
to allow the formation of subatomic particles and later simple atoms.
Giant clouds of these primordial elements later coalesced through
gravity in halos of dark matter, eventually forming the stars and
galaxies visible today.

Physics | The Mysteries of Antimatter

Δημοσιεύτηκε στις 13 Αυγ 2017

In
particle physics, antimatter is a material composed of the antiparticle
"partners" to the corresponding particles of ordinary matter. A
particle and its antiparticle have the same mass as one another, but
opposite electric charge and other quantum numbers. For example, a
proton has positive charge while an antiproton has negative charge. A
collision between any particle and its antiparticle partner leads to
their mutual annihilation, giving rise to various proportions of intense
photons (gamma rays), neutrinos, and sometimes less-massive
particle–antiparticle pairs. The consequence of annihilation is a
release of energy available for heat or work, proportional to the total
matter and antimatter mass, in accord with the mass–energy equivalence
equation, E = mc2.

The Fourth Phase of Water: Dr. Gerald Pollack at TEDxGuelphU

            

The Fourth Phase of Water: Dr. Gerald Pollack at TEDxGuelphU

Δημοσιεύτηκε στις 6 Σεπ 2013

Does water have a fourth phase, beyond solid, liquid and vapor?

University
of Washington Bioengineering Professor Gerald Pollack answers this
question, and intrigues us to consider the implications of this finding.
Not all water is H2O, a radical departure from what you may have
learned from textbooks.

Pollack received his PhD in biomedical
engineering from the University of Pennsylvania in 1968. He then joined
the University of Washington faculty and is now professor of
Bioengineering. His interests have ranged broadly, from biological
motion and cell biology to the interaction of biological surfaces with
aqueous solutions. His 1990 book, Muscles and Molecules: Uncovering the
Principles of Biological Motion, won an "Excellence Award" from the
Society for Technical Communication; his more recent book, Cells, Gels
and the Engines of Life, won that Society's "Distinguished Award."
Pollack received an honorary doctorate in 2002 from Ural State
University in Ekaterinburg, Russia, and was more recently named an
Honorary Professor of the Russian Academy of Sciences. He received the
Biomedical Engineering Society's Distinguished Lecturer Award in 2002.
In 2008, he was the faculty member selected by the University of
Washington faculty to receive their highest annual distinction: the
Faculty Lecturer Award. Pollack is a Founding Fellow of the American
Institute of Medical and Biological Engineering and a Fellow of both the
American Heart Association and the Biomedical Engineering Society. He
is also Founding Editor-in-Chief of the journal, WATER, and has recently
received an NIH Transformative R01 Award. He was the 2012 recipient of
the Prigogine Medal and in 2013 published his new book: The Fourth Phase
of Water: Beyond Solid, Liquid, and Vapor.


In the spirit of
ideas worth spreading, TEDx is a program of local, self-organized events
that bring people together to share a TED-like experience. At a TEDx
event, TEDTalks video and live speakers combine to spark deep discussion
and connection in a small group. These local, self-organized events are
branded TEDx, where x = independently organized TED event. The TED
Conference provides general guidance for the TEDx program, but
individual TEDx events are self-organized.* (*Subject to certain rules
and regulations)

beta minus decay.
This does assume some knowledge of sub-atomic particles.

Fans
of particle physics often encounter a series of doodles called Feynman
diagrams. These mystifying scribbles were invented by Richard Feynman
and they encode information on how particle physics collisions unfold.
But they have an even deeper significance. In this video, Fermilab’s
Dr. Don Lincoln gives you a peek into the deeper meaning of these
important scientific pictograms.

Previous Episode:
The Real Star Wars
https://www.youtube.com/watch?v=Q8shn...

Feynman’s
path integral shows us that, to properly calculate the probability of a
particle traveling from point A to point B, we need to add up the
contributions from all conceivable paths between those points –
including the impossible paths! In fact we can go even further:
according to Feynman’s approach, every conceivable happening that leads
from a measured initial state to a measured final state DOES in a sense
happen. To calculate the probability of any quantum system evolving from
one state into any other state we need to sum over every conceivable
intermediate state. This is impossible because there are infinite
possible intermediate states.

Isaac
Newton’s Universal Law of Gravitation tells us that there is a
singularity to be found within a black hole, but scientists and
mathematicians have found a number of issues with Newton’s equations.
They don’t always accurately represent reality. Einstein’s General
Theory of Relativity is a more complete theory of gravity. So does using
the General Theory of Relativity eliminate the singularity? No. Not
only does it concur with Newton’s Universal Law of Gravitation but it
also reveals a second singularity, not at the center of the black hole
but at the event horizon.
