Ephemeral vortices that form in the vacuum of space may have been spotted for the first time. They could help to explain how matter gets much of its mass.

Most of the mass of ordinary matter comes from nucleons � protons and neutrons. Each nucleon, in turn, is made of three quarks. But the quarks themselves account for only about 1 per cent of the mass of a nucleon. The remainder of the mass comes from the force that holds the quarks together. This force is mediated by particles called gluons.

A theory called quantum chromodynamics is used to calculate how quarks and gluons combine to give mass to nucleons, but exactly how this phenomenon works is not fully understood.

One possibility is that the fields created by gluons can twist, forming vortex-like struc

Earliest starlight of the universe is revealed

http://www.newscientist.com/article/dn8255-earliest-starlight-of-the-universe-is-revealed.html

* 18:00 02 November 2005 by Maggie McKee

NASA's Spitzer Space Telescope may have detected the infrared glow from the very first generation of stars, a new study reports. If confirmed, the work would reveal the structure of the universe a few hundred million years after the big bang, when the galaxies that exist today were just beginning to take shape.

Astronomers have already detected light from even earlier times, when the universe was a mere 370,000 years old. It was then that radiation first escaped from a scalding primordial soup of matter and energy, and it still suffuses space today in the form of the cosmic microwave background radiation.

But infrared light also floods space in what is called the cosmic infrared background radiation. "It is a repository of the emissions of all the stars that have ever existed in the un

No, I don't even know what that is...from context, I assume some sort of TV show.

In any case, You're misinterpreting what I mean by fuel. I fully accept that we can't harvest antirocks out of the earth an burn them. What I'm talking about is taking some other sort of energy (solar, nuclear, whatever), and converting it into antimatter. The reason for this is that a small amount of antimatter has a ridiculous energy density, so in cases where the weight of the fuel is important (like rocket launches), it will make an excellent fuel, no matter where the energy to make it came from in the first place.

Well, a tiny amount of antimatter produces a ridiculous high amount of energy but you need a ridiculous high amount of energi to produce a tiny amount of antimatter. Now remember that there is no 100% efficient energy conversion(most of the energy used to produce antimatter will be lost and most of the energy got from antimatter will be lost too) and that store something that reacts with any matter need constant energy use this isn't a great thing to use as fuel.

TL;DR too expensive and, instable and too hard to store.

I originally thought antimatter had negative mass. Unfortunately most physicists contend that while everything else is opposite, it has positive mass. So someone can't build an anti-matter bomb and have say, the Empire State Building vanish, which would be cool and also scary.

There are patterns inside the number sequence of pi. They are fucking strange. Pattern complexes when you combine the numbers into different forms. Blocks of five. Every five numbers combined equals one number. Printed out with hundreds of 5 number sets combined into different sets reveals ridiculous patterns and combination's of numbers. Patterns are to be seen in ten block sets. In odd/even number sets. Set all of the numbers of Pi out in just odd or just even. Put those into block sets. Patterns in primes, patterns in Mandelbrot sets when input with pi combination's. Simply put a sphere or a circle is the most efficient way for energy to take shape.

I cannot talk more on this subject. I feel that I am under surveillance.

Do not look simply in the numbers, it is in how the numbers are used.

A 48-year-old woman with a stimulating electrode implanted in her right ventral thalamus started to compulsively self-stimulate when she discovered that it could produce erotic sensations.

This is a report from the early days of deep brain stimulation, way back in 1986, from an article for the medical journal Pain which discussed some unintended side-effects from one patient's DBS treatment for chronic pain.

Soon after insertion of the nVPL electrode, the patient noted that stimulation also produced erotic sensations. This pleasurable response was heightened by continuous stimulation at 75% maximal amplitude, frequently augmented by short bursts at maximal amplitude. Though sexual arousal was prominent, no orgasm occurred with these brief increases in stimulation intensity. Despite several episodes of paroxysmal atrial tachycardia [heart disturbance] and development of adverse behavioural and neurological symptoms during maximal stimulation, compulsive use of the stimulator d

Since this is the most generic board of this "chan", What book are you reading now (apart of the ones for uni/school)

Picture related, I'm a medical student and I'm reading this. It's not a true medical book, more like a book written by a medic about medical mysteries like phantom limbs, blind vision and how our brains work.

The only bad thing about this book is that the one who translated it ot my language wasn't in the medical area so some terms were misstranslated...

Sun Tzu said...

All warfare is based on deception. [1:18]

Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near. [1:19]

Hold out baits to entice the enemy. Feign disorder, and crush him. [1:20]

The spot where we intend to fight must not be made known; for then the enemy will have to prepare against a possible attack at several different points; and his forces being thus distributed in many directions, the numbers we shall have to face at any given point will be proportionately few. [6:16]

Rapidity is the essence of war: take advantage of the enemy's unreadiness, make your way by unexpected routes, and attack unguarded spots. [11:19]

In a tour de force of office supply physics, researchers at the University of California, Los Angeles, have shown that it is possible to produce X-rays by simply unrolling Scotch tape.

Next step: nuclear fusion.

�We�re going to do that,� said Seth J. Putterman, a professor of physics at U.C.L.A. �I think it will work.�

But first, X-rays.

In the current issue of the journal Nature, Dr. Putterman and his colleagues report that surprisingly fierce flows of electrons were unleashed as the tape was unpeeled and its gooey adhesive snapped free of the surface. The electrical currents, in turn, generated strong, short bursts of X-rays � each burst, about a billionth of a second long, contained about 300,000 X-ray photons.

All of the experiments were conducted with Scotch tape, manufactured by 3M. The details of what is occurring on the molecular scale are not known, the scientists said, in part because the Scotch adhesive remains a trade secret.

Other brands of clear adhesive tapes also gave off X-rays, but with a different spectrum of energies. Duct tape did not produce any X-rays, Dr. Putterman said. Masking tape has not been tested.

The research opens up the possibility of looking for X-ray emissions from composite materials as they fatigue. Such materials, increasingly used in airplanes and automobiles, do not show the visible weaknesses that metals do before breaking.

The tape phenomenon could also lead to simple medical devices using bursts of electrons to destroy tumors. The scientists are looking to patent their ideas.

Finally, there is the possibility of nuclear fusion. If energy from the breaking adhesive could be directed away from the electrons to heavy hydrogen ions implanted in

It is very likely it was discovered by accident. Many important discoveries in Science were originally discovered by accident or while looking for a different result.

It said it only occurs while in a vacuum or possibly a very dry environment where the water in the air would not short it out. Maybe some scientists were working in a vacuum and pulled out some tape to fix an experiment and whallagh.

If it faster than light travel as easy as in sci fi is possible and there are many advanced civilizations in universe much older than we are them why they are not everywhere? They should be in the Earth, Moon, Mars, terraformed Venus, and some moons of giant planets for thousand of years.
Since they are not this means that travel in space is not easy (take too long), too expensive, or there aren't so many advanced civilizations around.

Start thinking and planning on a scale of time that is millions of years, not lifetimes.

It would be much easier to seed a planet and let that planet develop and seed 1 other or 2 other planets, in order to spread intelligent life, than to go there yourself, with the limits the lifespan.

The bloom of this "viral" campaign would be much faster than light travel.

Another concept that I personally think is more likely is that generally speaking each planet that can support life eventually creates and starts the evolutionary process...

And, that most of the Universe is within a certain age range (AROUND US), and evolution being a LAW of nature, occurs and approximately the same pace on all the similar aged planets, so AROUND US, so that in our section of the Universe we're all (of the planets capable of it) are developing at about the same pace...so we're all at about the same technological age, give or take a million years...(which is really close)

The problem is that our current Science has really good Evidence that Fully Matured Galaxies have been around for as soon as less than 1 Billion years after the big bang. That would give other species a 12 Billion year + head start on us. It is absolutely possible that a species came to our current level of technology 12 Billion years ago. The range of prediction for the Evolution of a species 12 Billion years ahead of our own is astounding.

In fact our own Milky Way Galaxy is estimated to be 13 Billion years old, as old as the current estimates for our Universes age. That means that life could have evolved BILLIONS of years ahead of our own inside our own Milky Way Galaxy!

Or to put it in a way that actually makes sense. there are untold billion stars. If one tenth of one percent of each of those stars has a habitable planet. and 1/1000'th of those potential habitable planets gave rise to life. and if say 1/100 of those life bearing planets gives rise to intelligent life....and if..say. Half of those make it out into space?

There are more habitable planets out in the universe than anyone could possibly care about. So why try to terriform shitty little balls like mars.

These sounds are of very low frequency, generally below the 50Hz range and are of unknown origin with ranging characteristics.

Based on experiences with Earth, the environment of a planet can be altered deliberately: however the feasibility of creating an unconstrained planetary biosphere that mimics Earth on another planet has yet to be verified. Mars is considered by many to be the most likely candidate for terraformation. Much study has been done concerning the possibility of heating the planet and altering its atmosphere, and NASA has even hosted debates on the subject. Several potential methods of altering the climate of Mars may fall within humanity's technological capabilities, but at present the economic resources required to do so are far beyond that which any government or society is willing to allocate to the purpose. The long timescales and practicality of terraforming are the subject of debate.

In the not-too distant future, population growth and demand for resources may create pressure for humans to colonize new habitats such as the surface of the Earth's oceans, the sea floor, near-Earth orbital space, the moon and nearby planets, as well as mine the solar system for energy and materials.

Mars already consists of many soil minerals that could theoretically be used for terraforming. Additionally, recent research has revealed large amounts of ice permafrost just below the Martian surface down to latitude 60, as well as on the surface at the poles, where it is mixed with dry ice, frozen CO2. It has also been hypothesized that there are vast amounts of ice in the deeper crust. As frozen carbon dioxide (CO2) at the poles sublimes back into the atmosphere during the Martian summer, a small amount of water residue is left behind, which fast winds then sweep off the poles at speeds approaching 250 mph (400 km/h). This seasonal ocurrence transports large amounts of dust and water vapor into the atmosphere, giving rise to Earth-like cirrus clouds.

Oxygen is only present in the atmosphere in trace amounts, but is present in large amounts in metal-oxides on the Martian surface. Some oxygen is also present in the soil in the form of per-nitrates. An analysis of soil samples taken

It has been suggested that Mars once had an environment relatively similar to that of Earth during an earlier stage in its development. This similarity is indicated by the thickness of the Martian atmosphere, as well as the evident presence of liquid water on the planet's surface in the past. The atmosphere has thinned over millions of years as gases have escaped into space, although it has also partially condensed into solid form. While water once appears to have existed on the Martian surface, it now only appears to exist at the poles and just below the planetary surface as permafrost. The exact mechanisms which led to the current atmospheric conditions on Mars are not fully known, although several hypotheses have been proposed. One hypothesis is that the gravity of Mars today indicates that lighter gases in the upper atmosphere could have contributed to the thinning of the atmosphere, with the excess atoms escaping into space.
