How To Make a Quantum Bit

Can You Solve This?
Posted by info on 08:23
How do you investigate hypotheses? Do you seek to confirm your theory -
looking for white swans? Or do you try to find black swans? I was
startled at how hard it was for people to investigate number sets that
didn't follow their hypotheses, even when their method wasn't getting
them anywhere.
In the video I say "when people came to
Australia..." by which I meant, "when Europeans who believed all swans
were white came to Australia..." I did not mean any offence to
Indigenous Australians who were already in Australia at that time.
Please accept my apologies for the poor phrasing if you were offended by
it.
This video was inspired by The Black Swan by Nassim Taleb and filmed by my mum. Thanks mum!
Partly
my motivation came from responses to my Facebook videos - social media
marketers saying 'Facebook ads have worked for me so there can't be fake
likes.' Just because you have only seen white swans, doesn't mean there
are no black ones. And in fact marketers are only looking for white
swans. They think it was invalid of me to make the fake Virtual Cat
page: 'well of course if it's a low quality page you're going to get low
quality likes.' But my point is this is black swan bait, something they
would never make because their theory is confident in the exclusive
existence of white swans.
Anti-Gravity Wheel?

Huge thanks to A/Prof Emeritus Rod Cross, Helen Georgiou for filming,
Alex Yeung, and Chris Stewart, the University of Sydney Mechanical
Engineering shop, Duncan and co. Ralph and the School of Physics.
In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it's spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was 'light as a feather' and could not be explained by Newton's Laws. I wanted to find out for myself what I really felt like.

Can Silence Actually Drive You Crazy?
Posted by info on 08:16
Many stories have circulated claiming the longest anyone has stayed in
an ultra-quiet anechoic chamber is 45 minutes, the reason being any
longer would drive you insane. To me this sounded like unsubstantiated
rubbish, like the claim the Great Wall is the only manmade structure
visible from space. So I put my own psyche on the line, subjecting
myself to over an hour of the most intense quiet on Earth. No, this was
not THE quietest room on Earth (-9dB) but it is one of the quietest, and
the truth is once you put a person inside, they are by far the loudest
thing in there so the sound rating of the room is irrelevant.
I was not surprised to find that I could stay in there for as long as I liked and feel perfectly fine. What was surprising is that my heartbeat was audible. You can hear it on the sound recording. Now I wasn't consciously aware of the sound of my heart while in the room, but I was more aware of the feeling of it beating.
Huge thank you to everyone at BYU: Duane Merrell, Spencer Perry, Cameron Vongsawad, Jazz Myers, Ann Clawson, and Robert Willes.

Dirtbike Backflips over Aerobatic Plane
On a sunny, windless, fall morning, Glen Dell took off from a remote airstrip in the North West bushveld to perform a stunt with FMX rider Nick de Wit. He was to fly his Extra 300 aerobatics aircraft low enough for Nick to backflip his dirtbike over it.Under Over was the culmination of two years of detailed planning, and would ultimately become the final building block in an aviation legacy that spans 30 years and over 25,000 hours on over 250 different types of aircraft. 5 weeks after completing this project, Glen was fatally injured while performing at an air show in Secunda, South Africa. This video is in memory of Glen's unbelievable aviation legacy. RIP Glen.

5 Most Mysterious Sounds Ever Recorded
Posted by info on 11:10
From mysterious sounds in the sky to strange sounds in the sea,
unexplained sounds have been reported worldwide. These are the top
strange noises reported around the world, including creepy Russian
numbers stations like UVB-76, the underwater Bloop sound, an unexplained
hum - sometimes known as the Taos hum - vibrating the air in places as
far apart as Canada and Australia, mysterious booms rocking the sky, and
the odd whale sounds of the 52 hertz whale -- the loneliest whale in
the world.
These strange sounds have been reported throughout history, but some continue through 2014 and today. Just what are these strange, sometimes scary noises? Are they signs of the apocalypse? Caused by government projects like HAARP, secret Air Force jets or even NASA? Or perhaps there are reasonable, less apocalyptic explanations... Turn up the volume, and watch to find out!

Saturn's Mysterious Moons
Posted by info on 11:02
Launched three years before the new century... a spacecraft wound its
way through the empty reaches of the solar system. On Earth, its
progress was little noted, as it swung twice by the planet Venus, then
our moon. And Earth. The asteroid belt. And Jupiter.
Almost seven years later, on the first of July 2004, the Cassini probe entered the orbit of Saturn. It then began to compile what has become one of the greatest photographic collections of all time, of a giant gas planet, surrounded by colorful rings, guarded by a diverse collection of moons, and millions of tiny moonlets.
Within this record, is a trail of clues... pointing to the energy sources and complex chemistry needed to spawn life. What are these mysterious worlds telling us about the universe, and Earth?
In the outer reaches of the solar system, a billion and a half kilometers from the Sun... there is a little world known as Enceladus. Nearly all of the sunlight that strikes its icy surface is reflected back into space, making it one of the brightest objects in the solar system.
At its equator, the average temperature is minus 198 degrees Celsius. It can rise about 70 degrees higher in grooves that stretch across the south pole like tiger stripes. Looming over it is the giant planet Saturn.
In myth, Saturn - the Roman name for the primal Greek God Chronos - was the youngest son of Gaia, or Earth, and Uranus, sky. Wielding a scythe provided by his mother, the story goes, Saturn confronted his abusive father, castrating him. The blood of Uranus flowed into the seas, fertilizing the Earth and giving rise to Enceladus and other giant offspring.
Saturn's moon Enceladus has its own tangled story. In 2005, the Cassini spacecraft spotted plumes of water vapor shooting out into space from its south pole.
More recent close encounters have revealed jets of water, flavored by slightly salty chemical compounds, spewing out from vents in the rough, cracked polar terrain. That may mean that Enceladus harbors a remarkable secret below its frigid surface: A liquid ocean, and perhaps, a chemical environment that could spawn simple life forms.
It's not the only promising stop in the realm of Saturn. The moon Titan is often said to resemble Earth in its early days. It is lined with volcanoes and a hazy atmosphere rich in organic compounds.
While Enceladus is the size of Great Britain, Titan is ten times larger, 50% larger than our moon, and the second largest moon in our solar system.
We've known about Titan since the astronomer Christian Huygens discovered it in 1655, and Enceladus since William Herschel spotted it in August 1789, just after the start of the French Revolution.
Scientists began to investigate these moons in earnest with the launch of the two Voyager spacecraft in 1977. The lineup of outer planets in the solar system allowed the spacecraft to fly past each of them.
They disclosed new details about their magnetic fields, atmospheres, ring systems, and inner cores. But what really turned heads were the varied shapes and surfaces of their moons.
They've all been pummeled over the millennia by wayward asteroids and comets. A few appear to be sculpted by forces below their surfaces. Neptune's largest moon Triton has few craters. It's marked with circular depressions bounded by rugged ridges. There are also grooves and folds that stretch for dozens of miles, a sign of fracturing and deforming.
Triton has geysers too, shooting some five miles above the surface. But on this frigid moon -- so far from the Sun -- the liquid that spouts is not water but nitrogen.
Tiny Miranda, one of 27 known moons that orbit Uranus, wears a jumbled skin that's been shaped and reshaped by forces within. Jupiter's moon Io -- orbiting perilously close to the giant planet is literally turning itself inside out. Rivers of lava roll down from open craters that erupt like fountains.
Flying by Europa, Voyager documented a complex network of criss-crossing grooves and ridges. In the 1990s, the Galileo spacecraft went back to get a closer look. It found that Europa's surface is a crazy quilt of fractured plates, cliff faces and gullies... amid long grooves like a network of superhighways. How did it get like this?
Then, heat rising up through a subsurface ocean of liquid water cracks, and shifts, and spreads the icy surface in a thousand different ways. Europa's neighbors, Callisto and Ganymede, show similar features, suggesting they too may have liquid oceans below their surfaces.
Crossing outward to Saturn, Voyager found a similar surface on the moon Enceladus. So when the Cassini spacecraft arrived in 2004, it came looking for answers to a range of burning questions: if this moon and others have subsurface oceans? Do they also have the ability to cook up and support life? And what could they tell us about the origin of life throughout the galaxy?

Mars: World That Never Was
Posted by info on 11:00
Did Mars long ago develop far enough for life to arise? If so, does
anything still live within Mars' dusty plains, beneath its ice caps, or
somewhere underground?
In 1964 the Mariner Four spacecraft flew by Mars and got a good look. What it saw looked more like the Moon than the Earth. Then, in the mid-1970's, two lander-orbiter robot teams, named Viking, went in for an even closer look. The landers tested the soil for the chemical residues of life. All the evidence from Viking told us: Mars is dead. And extremely harsh.
The mission recorded Martian surface temperatures from -17 degrees Celsius down to -107. We now know it can get even colder than that at the poles. The atmosphere is 95% carbon dioxide, with only traces of oxygen. And it's extremely thin, with less than one percent the surface pressure of Earth's atmosphere.
And it's bone dry. In fact, the Sahara Desert is a rainforest compared to Mars, where water vapor is a trace gas in the atmosphere. On Earth, impact craters erode over time from wind and water... and even volcanic activity. On Mars, they can linger for billions of years.
Earth's surface is shaped and reshaped by the horizontal movement of plates that make up its crust driven by heat welling up from the planet's hot interior. At half the width and only 11% the mass of Earth, Mars doesn't generate enough heat to support wide-scale plate tectonics.
Nor does it have the gravity to hold a thick atmosphere needed to store enough heat at the surface to allow liquid water to flow. Nonetheless, some areas that looked to Viking-era scientists like craters and volcanic areas, were later shown to be riverbeds, lake bottoms, and ocean shorelines.
If water once flowed on Mars' surface, where did it all go?
This was the scene at NASA's Jet Propulsion Lab in 2004. The twin rovers Spirit and Opportunity had just bounced down on the Red Planet. When the excitement died down, the rovers were set off on one of the most remarkable journeys in the history of planetary exploration. Missions like this could one day pave the way for a day when we'll view images from a real astronaut's camera.
Opportunity had come to rest in a small crater near the equator, at a spot called Meridiani Planum. Here, in plain view, on a nearby crater wall, its camera revealed exposed bedrock, the first ever seen on Mars. Not far away, the rover found layered rocks on the face of a cliff. On Earth, they typically form as sedimentary layers at the bottom of oceans.
And at every turn, Opportunity rolled across tiny, smooth, round pellets. They became known as "blueberries" because they appeared purplish-brown against Mars' rust-colored surface. Initially thought to be volcanic in origin, they turned out to be iron-rich spherules of the type that form within cavities in the mud at the bottom of an ocean.
Drilling into rocks, the rover inserted a spectrometer to read the mineral content. The readings showed significant amounts of sulfate salt, a tracer for standing water. That wasn't all. Spirit's broken wheel, dragging behind it, exposed soils saturated in salt.
Clearly there once was water on Mars' surface, but how long ago? And, if there is anything left, where would you find it? One possible answer: the North Pole. From orbit, this region seemed to be covered in frozen CO2 - what we call dry ice. But was there water ice below the surface?
Enter Phoenix, a lander that touched down near the North Pole in early 2008. Radar readings from orbit, taken by the Mars Express mission, hinted at the presence of ice just below the surface.
The Phoenix lander's descent thrusters blew away the top layer of soil, allowing its camera to snap pictures of what looked like ice. Scientists instructed the robot to conduct a simple experiment: reach out and dig a trench, then watch what happens.
As expected, clumps of white stuff appeared. A couple of days later, it was gone. Vaporized. That means it can't be salt or frozen CO2, which is stable in the cold dry temperatures of the Martian pole. So it had to be water, the first ever directly seen on Mars.
There are indications that the North Pole was actually warm enough in the recent past for water ice to become liquid. The Mars Reconaissance Orbiter, or MRO, used radar pulses to peer beneath the surface of the ice cap. These data reveal that the ice, just over a mile thick, formed in a succession of layers as the climate alternated between warm and cold.
Our planet avoids mood swings like this in part because its spin is stabilized by a massive moon. Mars' spin is not, so it can really wobble, with the pole tilting toward the sun for long periods. New observations by the MRO spacecraft show that these wobbles can lead to dramatic releases of CO2, and warming periods due to an increase in the greenhouse effect.

Swiss Alps expected to open in 2016. With a route length of 57 km (35.4
mi) and a total of 151.84 km (94.3 mi) of tunnels, shafts and passages,
it is the world's longest rail tunnel, surpassing the Seikan Tunnel in
Japan.
Its main purpose is to increase total transport capacity across the Alps, especially for freight, notably between Germany and Italy, and more particularly to shift freight volumes from road to rail to reduce environmental damage caused by ever-increasing numbers of heavy lorries. A secondary benefit will be to cut the journey time for passenger trains from ZĆ¼rich to Milan by about an hour and from ZĆ¼rich to Lugano to 1-hour 40 minutes.
The project consists of two single-track tunnels. It is part of the AlpTransit project, also known as the New Railway Link through the Alps (NRLA), which includes the Lƶtschberg Base Tunnel between the cantons of Bern and Valais and the under construction Ceneri Base Tunnel (scheduled to open late 2019) to the south. It bypasses the Gotthardbahn, a winding mountain route opened in 1882 across the Saint-Gotthard Massif, which is now operating at capacity, and establishes a direct route usable by high-speed rail and heavy freight trains.
The total cost of the project is 9.8 billion Swiss francs, or US$10.3 billion. When completed, the Gotthard Base Tunnel will be one of the longest tunnel construction projects in the world: 20 years of constant construction and preparation.

The Largest Oil Rig in The World
Posted by info on 10:47
Perdido is the deepest floating oil rig (platform) in the world at a
water depth of about 2450 meters operated by the Shell Oil Company in
the Gulf of Mexico.
The Perdido is located in the Perdido fold belt which is a rich discovery of crude oil and natural gas that lies in water that is nearly 8000 feet deep. The platform's peak production will be 100,000 barrels of oil equivalent per day. At 267 meters, the Perdido is nearly as tall as the Eiffel Tower.
An oil rig is a large structure with facilities to drill wells, to extract and process oil and natural gas, and to temporarily store product until it can be brought to shore for refining and marketing. In many cases, the platform contains facilities to house the workforce as well.

An-225 Mriya
The An-225 with Buran atop, at the Paris Air Show in 1989.
Role Strategic airlifter
National origin Soviet Union / Ukraine
Manufacturer Antonov
First flight 21 December 1988
Status In service
Primary user Antonov Airlines
Produced 1988
Number built 1
Developed from Antonov An-124
The Antonov An-225 Mriya (Ukrainian: ŠŠ½ŃŠ¾Š½Š¾Š² ŠŠ½-225 ŠŃŃŃ, Dream, NATO reporting name: 'Cossack') is a strategic airlift cargo aircraft, designed by the Soviet Union's Antonov Design Bureau in the 1980s. The An-225's name, Mriya (ŠŃiŃ) means "Dream" (Inspiration) in Ukrainian. It is the largest airplane in the world; it is the heaviest aircraft with a gross weight of 640 tonnes and the biggest heavier-than-air aircraft in terms of length and wingspan in operational service.
The Antonov An-225, originally developed specifically to transport the Buran spaceplane, was an enlargement of the successful Antonov An-124. The first An-225 was completed in 1988 and a second An-225 has been partially completed. The completed An-225 is in commercial operation with Antonov Airlines carrying oversized payloads.[1] Among its many records, it holds the absolute world record for airlifted payload at 189,980 kilograms (418,834 pounds).[2][3]
The Antonov An-225 was designed to airlift the Energia rocket's boosters and the Buran space shuttle for the Soviet space program. It was developed as a replacement for the Myasishchev VM-T. The An-225's original mission and objectives are almost identical to that of the United States' Shuttle Carrier Aircraft.[4][5]
The An-225 first flew on 21 December 1988 with a 74 minute flight from Kiev. The aircraft was on static display at the Paris Air Show in 1989 and it flew during the public days at the Farnborough air show in 1990. Two aircraft were ordered, but only one An-225 (registration CCCP-82060 later UR-82060[6]) was finished. It can carry ultra-heavy and oversize freight, up to 250,000 kg (550,000 lb) internally,[4] or 200,000 kg (440,000 lb) on the upper fuselage. Cargo on the upper fuselage can be 70 metres (230 ft) long.[7]
A second An-225 was partially built during the late 1980s for the Soviet space program. The second An-225 included a rear cargo door and a redesigned tail with a single vertical stabilizer. It was planned to be more effective for cargo transportation.[8] Following the collapse of the Soviet Union in 1991 and the cancellation of the Buran space program, the lone operational An-225 was placed in storage in 1994.[9] The six Ivchenko Progress engines were removed for use on An-124s, and the second uncompleted An-225 airframe was also stored. The first An-225 was later re-engined and put into service.[10][11]
By 2000, the need for additional An-225 capacity had become apparent, so the decision was made in September 2006 to complete the second An-225. The second airframe was scheduled for completion around 2008,[12] then delayed. By August 2009, the aircraft had not been completed and work had been abandoned.[1][13] In May 2011 Antonov CEO is reported to have said that the completion of a second An-225 Mriya transport aircraft with a carrying capacity of 250 tons requires at least $300 million, but if the financing is provided, its completion could be achieved in three years.[14] According to different sources, the second jet is 60--70% complete.[15]
