Fractional Distillation Of Air

Did you know that the air we breathe isn’t just oxygen, infact it’s made up of a number of different gases such as nitrogen, oxygen, carbon dioxide, argon, neon and many others. Each of these gases carry useful properties so separating them from the air around us is extremely beneficial.

The process is called fractional distillation and consists of two steps, the first relies on cooling the air to a very low temperature (i.e. converting it into a liquid), the second involves heating it up thus allowing each gas within the mixture to evaporate at its own boiling point. The key to success here is that every element within air has its own unique boiling temperature. As long as we know these boiling temperatures we know when to collect each gas.

So what are the real world benefits of separating and extracting these gases? Well liquid oxygen is used to power rockets, oxygen gas is used in breathing apparatus, nitrogen is used to make fertilizers, the nitric acid component of nitrogen is used in explosives.

The other gases all have their own uses too, for example argon is used to fill up the empty space in most light bulbs (thanks to its unreactive nature). Carbon dioxide is used in fire extinguishers and is great for putting out fires in burning liquids and electrical fires. There really are too many uses to list but suffice it to say that fractional distillation is an extremely useful process for humans the world over.

History Made as 90,000 Earthlings Send Messages to Mars


There’s really a more productive way to spend Black Friday instead of going berserk and storming the stores. A really huge crowd of 90,000 people capable of invading every bigger mall during the yesterday’s run-and-buy frenzy, has made history sending greetings to our reddish neighboring planet. “Today uwingu.com sent almost 90,000 messages to Mars—first time people’s names & messages sent to Mars by radio!” the Uwingu company which crowd funds space projects, said on Twitter. It was a global shout-out event to mark the 50th anniversary of NASA’s Mariner 4 - the first mission to Mars.

Astronomers Observe a Spooky Alignment of Quasars


New observations with ESO’s Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the central supermassive black holes in a sample of quasars are parallel to each other over distances of billions of light-years. The team has also found that the rotation axes of these quasars tend to be aligned with the vast structures in the cosmic web in which they reside. A team led by Damien Hutsemékers from the University of Liège in Belgium used the FORS instrument on the VLT to study 93 quasars that were known to form huge groupings spread over billions of light-years, seen at a time when the Universe was about one third of its current age. "Alignments between galaxy axes and large-scale structures are expected in theories of structures and galaxy formation. The alignments between quasar axes and large-scale structures are found on much larger scales so that it is a bit mysterious and a challenge for the theory," Hutsemékers told astrowatch.net. The research was presented in a paper entitled “Alignment of quasar polarizations with large-scale structures“, by Damien Hutsemékers et al., to appear in the journal Astronomy & Astrophysics on 19 November 2014.

New theory says that death does not exist!

does not exist
Many of us fear death. We believe in it because we were told that we will die.

People associated with the bodies, and as we know, the body dies. However, new scientific theory holds that death is not the final event, says Robert Lanza, an expert in advanced cell technology on his blog.

One well-known aspect of quantum physics is that certain observations can not be predicted absolutely. Instead, there are a number of possible observations, each with a different probability.

One frequent explanation, interpretation of the "many worlds", argues that each of these possible observations corresponds to a different universe (multiverse).

A new scientific theory called biocentrism bit cleared these ideas. There are an infinite number of universes, and everything that could possibly happen, it happens in them. Death does not exist in the real sense in these scenarios. All possible universes exist simultaneously, regardless of what happens in them.

Although our bodies are destined to be destroyed, the sense of life - "Who am I?" Is actually a fountain of energy of 20 watts, which controls the brain. However, this energy does not disappear after death. One of the most reliable axioms of science is that energy never dies - it can neither be created nor destroyed.


Whether this energy is transferred from one world to another?

Judging by biocentrism, space and time are not the hard objects the way you think. If you wave your hand through the air - if you remove everything, what's left? It's nothing.

The same thing can be applied to time. We can not see anything through the bone that surrounds your brain. Everything we see and feel is currently the vortex of information that is going on in our head. Space and time are only tools used to make everything connect.

Death does not exist in a timeless and spaceless world.

At the very end, even Albert Einstein admitted, "My old friend has left this strange world in front of me. It does not mean anything. People like us know that the distinction between past, present and future only stubbornly persistent illusion. "

Immortality does not mean continuous existence in time without end, it is situated outside of time.

Astronomers Find Planet-forming Lifeline in a Young, Low-mass Binary Star System


Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a streamer of gas flowing from a massive outer disc toward the inner reaches of a young, low-mass binary star system GG Tau-A. The never-before-seen feature may be responsible for sustaining a second, smaller disc of planet-forming material that otherwise would have disappeared long ago. “We have demonstrated that the inner disks can be replenished with fresh material and are thereby potential sites of planet formation,” Emmanuel Di Folco, co-author of the study from the Laboratory of Astrophysics of Bordeaux, France told astrowatch.net. Our finding with ALMA is that there is a large amount of cold material that flows into the cavity (from the outer ring) towards the inner disk(s) and stars. The infalling material can nurture the inner disk(s) and extend their lifetime on timescales long enough to sustain planet formation therein.” The researchers detailed their findings in a paper to be published in the journal Nature on Oct. 30, 2014.

Astronomers Find Two Families of Comets Around Beta Pictoris


A French team of astronomers has discovered that two families of exocomets orbit the nearby star Beta Pictoris. The researchers used the HARPS instrument at ESO’s La Silla Observatory in Chile to make the most complete census of comets around another star ever created. "The expansive statistics of the comets that we observed with HARPS and the high quality of the instrument allowed us to distinguish two groups of detections," Flavien Kiefer of the Paris Institute of Astrophysics, lead author of the new study told astrowatch.net. "We found that these two groups were physically different and thus composed distinct families." The research was presented in a paper entitled "Two families of exocomets in the Beta Pictoris system" which is published in the journal Nature on Oct. 23.

Hidden Star Formation Found in a Protocluster


Astronomers have used the APEX telescope to probe a huge galaxy cluster that is forming in the early Universe and revealed that much of the star formation taking place is not only hidden by dust, but also occurring in unexpected places. The Spiderweb Galaxy (formally known as MRC 1138-262) and its surroundings have been studied for twenty years, using ESO and other telescopes, and is thought to be one of the best examples of a protocluster in the process of assembly, more than ten billion years ago. This is the first time that a full census of the star formation in such an object has been possible. "To obtain a full census requires a lot of observing time at a broad range of telescopes using different techniques. As the observing time is very expensive and hard to obtain, this can only be done in a few very carefully selected regions, such as the proto-cluster surrounding the Spiderweb Galaxy," Carlos De Breuck, APEX project scientist at ESO, and a co-author of the new study told astrowatch.net.
