Frustrated by not being able to sing two notes at the same time, musical inventor Beardyman built a machine to allow him to create loops and layers from just the sounds he makes with his voice. Given that he can effortlessly conjure the sound of everything from crying babies to buzzing flies, not to mention mimic pretty much any musical instrument imaginable, that’s a lot of different sounds. Sit back and let the wall of sound of this dazzling performance wash over you.

In a robot lab at TEDGlobal, Raffaello D’Andrea demos his flying quadcopters: robots that think like athletes, solving physical problems with algorithms that help them learn. In a series of nifty demos, D’Andrea show drones that play catch, balance and make decisions together — and watch out for an I-want-this-now demo of Kinect-controlled quads.
There’s more on Raffaello here where you can read this:
My work is focused on the creation of systems that leverage technological innovations, scientific principles, advanced mathematics, algorithms, and the art of design in unprecedented ways, with an emphasis on advanced motion control.
By their very nature, these creations require a team to realize. Many are enabled by the research I conduct with my graduate students. Many are also the fruit of collaborations with architects, entrepreneurs, and artists.
My hope is that these creations inspire us to rethink what role technology should have in shaping our future.

and where you can also find this further video – Zurich Minds – doubly fascinating.
The full description may be read here, but I have taken the liberty of republishing this extract:
Earth, which is 898 million miles (1.44 billion kilometers) away in this image, appears as a blue dot at center right; the moon can be seen as a fainter protrusion off its right side. An arrow indicates their location in the annotated version. The other bright dots nearby are stars.
Now it doesn’t take too much imagination to put that minute speck of light, our Planet Earth, into its scale of meaning and importance vis-a-vis the universe. You get my message, I’m sure.
The second event was a comment left by long-term reader and supporter of Learning from Dogs, Patrice Ayme. The comment was on yesterday’s post, The meaning of wildness, and I quote:
Excellent article. Clearly primary temperate rain forest, nearly gone everywhere except in the American North west, has to be reintroduced.
Sheep ought not to be removed by man, but be removed by wolf, bear, felids. Cows would feel whole, having to fight off lions. And man’s sense of what nature means, vital to insure our survival, would blossom in this hour of need, when we have arisen as the planet’s gods. gods of evil, or gods of wisdom? That is the most important question.
“gods of evil, or gods of wisdom?”
To everybody I say this. (And I am most certainly not excluding me.) When you next look at yourself in the mirror will you make a decision? Will you be a god of evil or a god of wisdom?
Dan sent me an email with a link to a most astounding video. But before we get to that, just take a look at these images. Here are the first three from the set of eight.
Eight breathtaking images of baby stars
1. Beautiful newborns
In a universe of fantastic images, a newborn star is a mystical masterpiece. Cradled within the dusty arms of a nebula, a baby star seems to blink its way to a new life. The lifespan of a star is a series of sequences. A star may spend most of its life in a “main sequence phase” where nuclear fusion of hydrogen into helium is happening in its core. But before this happens, it lives as a protostar, or baby star.
Thanks to NASA’s advanced infrared space telescopes such as Hubble and Spitzer, we are able to view these star births as never before. Pictured here are newborn stars peeking out “from beneath their natal blanket of dust” in the Rho Ophiuchi dark cloud as seen by the Spitzer Space Telescope. (Text: Katherine Butler)
2. Young stars in Serpens
Here the Spitzer Space Telescope reveals the Serpens South star cluster, in which 50 or so young stars exist. They are seen as the “green, yellow, and orange-tinted specks sitting atop the black dust lane.” A supernova or galaxy collision can cause a star to form when huge clouds of hydrogen and helium collapse under mutual gravity. As the cloud collapses, it heats up and starts to spin. Since protostars are covered in dust, they can be seen only through infrared telescopes like Hubble and Spitzer. As Universe Today writes, “After about 100,000 years or so, the protostar stops growing and the disk of material surrounding it is destroyed by radiation.” Then this star, now called a T Tauri or pre-main sequence star, is visible from Earth.
3. Bubbly little star
We are used to images of babies blowing bubbles, and it looks like the infants of the cosmos do the same. This image, taken by the Spitzer Space Telescope, shows the HH 46/47 baby star blowing bubbles into space via powerful jets of gas. Located about 1,140 light-years from Earth, HH 46/47 is the bright white star at the middle of the image. Two bubbles reach out in opposite directions and are formed when the jets collide with the dust and gas surrounding the star. As Universe Today reports, “Astronomers think that young stars accumulate material by gravitationally pulling in gas and dust. This process ends when the star gets large enough to create these jets. Any further material is just blown away into space.”
Go and view the remaining five stunning images here.
Now to what was sent by Dan.
Check out this mind-bending video that talks about the “Hubble Ultra Deep Field” image captured by NASA astronomers nearly a decade ago — a photograph that some call “the most important image ever taken.”
It all started back in 1996 when a group of astronomers pointed the Hubble Space Telescope at an empty patch in the sky close to the Big Dipper in hopes of seeing something, anything. At the time, it was considered to be a risky move, given that demand for use of the telescope was so high. What if the experiment yielded no results? What if nothing but an empty image was the final result?
After ten full days of exposing the telescope’s CCD camera sensor to this seemingly vacuous patch of sky, a breathtaking image was produced. Over three thousand galaxies appeared in one image — some as dots, others as spirals. It was a visual reminder of just how big our universe really is. The photo is called the “Hubble Deep Field“:
In 2004, astronomers pointed Hubble near constellation Orion and opened the shutter for a whopping 11 days. Using sensitive detectors and specialized filters, the telescope was able to capture an image with over 10,000 galaxies. This image became known as the “Hubble Ultra Deep Field.”
Scientists later used redshift calculations of the galaxies to turn the photograph into a “fly-thru” view of the photo:
It didn’t end there. Last year, NASA scientists created the Hubble Extreme Deep Field, which has an equivalent exposure time to 23 days and features. It’s the “deepest image of the sky ever obtained” that reveals “the faintest and most distant galaxies ever seen”:
And just think: scientists created these photos by pointing their mega-camera at a tiny speck of the night sky that appears to be completely devoid of visible stars!
oooOOOooo
“… a tiny speck of the night sky that appears to be completely devoid of visible stars!”
Dan said in his email, “Are we really here? What are the chances?”
You really have to wonder! Incredibly long odds. Both to us being here and to us being the only conscious, intelligent species in the universe.
Now I did say this was going to be an odd assortment of posts for a few days!
Back in my ‘previous’ life in SW England and together with a group of friends we formed an online aviation briefing company, called AvBrief rather unimaginatively! The UK Met Office have their headquarters in Exeter, Devon and AvBrief had a commercial relationship with the Met Office.
Although no longer resident in the UK, I still subscribe to the UK Met Office blog and find many of their posts interesting. Such as this one that came in yesterday.

Cyclone twins form in the Indian Ocean by Dave Britton
11th May, 2013
April to June each year usually sees the transition from the southern to the northern hemisphere tropical cyclone season.
During this time it is possible to see cyclones in both hemispheres simultaneously. Furthermore, cyclone ‘twins’ sometimes develop at approximately the same longitude either side of the equator.
For the first time since 2009 cyclone twins have developed in the Indian Ocean.
This was caused by a strong burst of westerly winds along the equator about a week ago. A large mass of clouds located in the same area initially moved eastwards with the wind.
The clouds furthest from the equator then started to curl northwards in the northern hemisphere and southwards in the southern hemisphere due to the earth’s rotation. Over time these cloud masses have consolidated and started to rotate to produce twin tropical storms.
The southern hemisphere storm has been named Jamala and is currently not expected to affect any land areas.
The northern hemisphere storm has been named Mahasen and there is a stronger likelihood of this making landfall next week on one of the Bay of Bengal’s coastal regions.
The Met Office routinely supplies predictions of cyclone tracks from its global forecast model to regional meteorological centres worldwide, which are used along with guidance from other models in the production of forecasts and guidance.
You can keep up to date with tropical cyclones around the world on our website or follow us on Twitter.

Yesterday, I reposted 12 stunning photographs of the world we live on that had been published on Mother Nature Network on the 19th.
Coincidentally, I also saw something on the 19th that was just as breathtaking as those pictures of Planet Earth. Here’s the picture that took my breath away.

Description: Stunning new view from ESA’s Herschel space observatory of the iconic Horsehead Nebula in the context of its surroundings. The image is a composite of the wavelengths of 70 microns (blue), 160 microns (green) and 250 microns (red), and covers 4.5×1.5 degrees. The image is oriented with northeast towards the left of the image and southwest towards the right.The Horsehead Nebula resides in the constellation Orion, about 1300 light-years away, and is part of the vast Orion Molecular Cloud complex. The Horsehead appears to rise above the surrounding gas and dust in the far right-hand side of this scene, and points towards the bright Flame Nebula. Intense radiation streaming away from newborn stars heats up the surrounding dust and gas, making it shine brightly to Herschel’s infrared-sensitive eyes (shown in pink and white in this image).To the left, the panoramic view also covers two other prominent sites where massive stars are forming, NGC 2068 and NGC 2071.
Extensive networks of cool gas and dust weave throughout the scene in the form of red and yellow filaments, some of which may host newly forming low-mass stars.
Don’t know about you but I found that description a little dry, so to speak.
By Jonathan Amos, Science correspondent, BBC News.
Europe’s Herschel space telescope has imaged one of the most popular subjects in the sky – the Horsehead Nebula – and its environs.
The distinctively shaped molecular gas cloud is sited some 1,300 light-years from Earth in the Constellation Orion.
It is in a region of space undergoing active star formation – something Herschel has been most keen to study.
The Hubble space observatory has also returned to the Horsehead scene, to celebrate 23 years in orbit.
Together, these two great facilities give scientists a much broader insight into what is taking place in this familiar patch of the heavens.
“You need images at all scales and at all wavelengths in astronomy in order to understand the big picture and the small detail,” said Prof Matt Griffin, the principal investigator on Herschel’s SPIRE instrument.
“In this new Herschel view, the Horsehead looks like a little feature – a pimple. In reality, of course, it is a very large entity in its own right, but in this great sweep of a picture from Herschel you can see that the nebula is set within an even larger, molecular-cloud complex where there is a huge amount of material and a great range of conditions,” the Cardiff University, UK, researcher told BBC News.
To provide a sense of scale, the Horsehead Nebula, also known in the catalogues as “Barnard 33”, is about five light-years “tall”.
Hubble’s new view of the Horsehead Nebula, a large cloud of hydrogen laced with dust.
Hubble sees the Horsehead in near-infrared light. Herschel, on the other hand, goes to much longer wavelengths. This allows it to see the glow coming directly from cold gas and dust – the material that will eventually collapse under gravity to form the next generation of stars.
Scientists are particularly keen to understand the mechanisms that drive the production of the biggest stars – objects much more massive than our own Sun that form relatively fast, burn bright but brief lives, and interact strongly with their environment, influencing the next round of star formation.
Anyway, that’s more than enough to copy directly from that BBC article. Read the rest by going here. All I will add is Jonathan’s last sentence, “A scholarly paper describing Herschel’s investigation of the Orion Molecular Cloud Complex has been published in the journal Astrophysical Journal Letters.”
Oh, and ponder on how far away from Earth is that Constellation Orion. Remember it was stated as 1,300 light-years.
Well, one light-year is just under 10 million, million kilometres (or about 6 million, million miles). Apparently defined by the IAU, or to give its the full name, the International Astronomical Union, a light-year is the distance that light travels in a vacuum in one Julian year.
So brace yourself! 1,300 light-years is just under 13,000,000,000,000,000 kilometres or in old money, 7,800,000,000,000,000 miles.
Rather puts pottering to the shops in Grants Pass into perspective!
Does rather serve to remind us of our place in the scheme of things.
This stunning image was taken by the Cassini-Huygens probe. Many of the images taken by NASA are available for download from the DVIDS website, which is where this one was found. (But also do visit the Ciclops website.)
The title of the photograph is:
A View of Earth from Saturn
Although the Earth Observatory typically reserves ”Image of the Day” space for publishing data and images acquired by Earth-observing satellites, we are sometimes so enthralled by the spectacular images acquired by spacecraft observing other parts of the solar system that we want to share these ‘otherworldy’ views with our visitors. And if you are looking for remotely sensed images of the Earth, this view is the most remotely sensed image we have ever published!
This beautiful image of Saturn and its rings looks more like an artist’s creation than a real image, but in fact, the image is a composite (layered image) made from 165 images taken by the wide-angle camera on the Cassini spacecraft over nearly three hours on September 15, 2006.
Scientists created the color in the image by digitally compositing ultraviolet, infrared, and clear-filter images and then adjusting the final image to resemble natural color. (A clear filter is one that allows in all the wavelengths of light the sensor is capable of detecting.) The bottom image [the one above. Ed.] is a closeup view of the upper left quadrant of the rings, through which Earth is visible in the far, far distance.
On this day, Saturn interceded between the Sun and Cassini, shielding Cassini from the Sun’s glare. As the spacecraft lingered in Saturn’s shadow, it viewed the planet’s rings as never before, revealing previously unknown faint rings and even glimpsing its home world. Seen from more than a billion kilometers (almost a billion miles) away, through the ice and dust particles of Saturn’s rings, Earth appears as a tiny, bright dot to the left and slightly behind Saturn.
Although it might appear that Earth is located within Saturn’s outermost rings, that positioning is just an illusion created by the enormous distance between Cassini and Earth. When Cassini took this image, the spacecraft was looking back at Saturn from a distance of about 2.2.million kilometers (about 1.3 million miles). The Sun was millions of additional miles beyond, hidden behind Saturn. On September 15, Earth’s orbit had brought our home planet to a location slightly behind and to the left of the Sun from Cassini’s perspective. The Website of the Cassini Imaging Central Laboratory for Operations (CICLOPS) provides more detailed information about this image. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency, and the Italian Space Agency.
Trying to find that faint image of Planet Earth in the above photograph is a challenge, even for those with much younger eyes than mine.
However, with a little bit of jiggery-pokery I was able to crop and enlarge the photograph, see below:
Planet Earth is in the ’10 o’clock’ position in the photograph, about half-way from the centre of the enlarged segment towards the top-left corner of the picture, just outside the outer white ring.
That’s us. All that we have ever been. All that we ever will be. Just that small white dot.
DA14, or to give it’s full name, Asteroid 2012 DA14, is calling by Planet Earth rather soon. To quote the item on the Planetary Society’s website,
Asteroid 2012 DA14 Discovery Enabled by Planetary Society Grant
On Friday, February 15, 2013, Asteroid 2012 DA14 will travel just 17,000 miles above the Earth – closer to our planet than the orbit of the communications satellite that broadcast the Super Bowl around the world. About half the size of a football field and with more than 100 times the energy impact of the nuclear bomb that fell on Hiroshima, DA14 will miss Earth this time around, but if it had impacted, this asteroid could have taken out any major metropolitan city on our planet.
The discovery of Asteroid DA14 was made by a small team of observers at La Sagra Observatory in Southern Spain, on February 22, 2012, enabled with a grant provided by The Planetary Society. One of the observatory’s telescopes had recently been upgraded with funds donated by The Planetary Society’s NEO Shoemaker Grant program. Its new camera enabled detection of fast moving objects like 2012 DA14 – requiring very fast imaging for discovery and determination of their paths. The upgraded instrument has far outperformed the Observatory’s other telescopes.
Now, we get to point the world’s telescopes at this 2013 close flyby and learn more about this asteroid and its orbit because of the support of our Planetary Society Members all over the world.
This asteroid won’t hit Earth, at least for many, many decades. But it is a reminder we live in a cosmic shooting gallery. We need to find, track, and characterize these objects and develop the technical and political capability to deflect an asteroid. It is not a matter of whether there will be a dangerous impact, it is a matter of when.
NASA have recently released a video, see below, but a search on YouTube will find more, some of which are more engaging than the rather dry style of the NASA release.
Have questions? Bet you do! Here are some of the answers to the obvious ones. Including these:
What is the time of closest approach
Feb. 15, 2013, 19:25 UTC (11:25 PST)
What is the closest approach altitude?
Approximate altitude above the surface of the Earth will be 27,330 km, 17,000 mi (34,100 km, 21,200 mi from center of Earth). That is closer than the altitude of geosynchronous satellites, e.g., satellite TV satellites, at 35,786 km (22,236 mi) altitude.
Will it be visible with the naked eye, how bright will it be?
It will not be a naked eye object. At closest approach, its brightness will be about a magnitude of 7. It will be bright enough that it could be seen with steady binoculars or a small telescope if you are on the side of Earth it will be passing.
What parts of Earth will have a chance to observe it telescopically?
Near closest approach when it is brightest, most of Europe, Asia, and Africa. It will pass from the southern hemisphere to northern hemisphere. Though it will be much dimmer, it is observable by larger telescopes for days to weeks before and after closest approach.
Finally, well done those gents that first spotted DA14.

In my recent post Electrosensitivity, I wrote about “spending a number of years studying for a Diploma in Electrical Engineering at Faraday House, Southampton Row, London and becoming a UK Radio Amateur at the age of 17 (G3PUK)“.
In reverse order, I shall start with becoming a UK Radio Amateur, now rather back in the mists of time!
After my father died in 1956 my mother subsequently remarried. Her new husband was Richard Mills and he was very knowledgeable about radio matters; he was a technical author in the radio-communications industry. It was Richard, my step-dad, who showed me how to make a crystal set and I started listening to the strange world of wireless radio. It fascinated me and motivated me to save up my pennies and buy an ex-military radio receiver known as a R1155.
I had joined the Harrow Radio Society who, amazingly, are still active today, as their website demonstrates.
Under the fabulous tutelage of many of the older ‘hams’ I went on to sit my exams and on Valentine’s Day 1962 was awarded the Postmaster-General’s Amateur Radio Certificate. I applied for a call-sign and was allocated G3PUK. I was just 17 years old!
oooOOOooo
Now some memories of Faraday House. I can do no better than refer you to an article that appeared on the Electrical Review website in the UK. As the article was published over three years ago, I think republishing it on Learning from Dogs isn’t being too naughty.
Faraday House Association closes after 105 years
FRIDAY, 29 JANUARY 2010
It is with sadness we report the Faraday House Old Students Association (FHOSA) is to close after operating continuously over the last 105 years. It had been host to thousands of chartered electrical engineers. The Association membership is derived from old students of Faraday House.
In 1888 the revised Electric Lighting Act encouraged many local authorities to apply for Parliamentary Powers to establish generating stations to transmit power. Faraday House was founded to train engineers in this new practice. The college started life as the Electrical Standardising, Testing and Training Institution at Charing Cross but in June 1890 used the name Faraday House. It was located in the Charing Cross area, and fees were 100 guineas per annum. The first Faraday House Dinner was held in 1895 – it was free and some 170 attended. In 1905 the FHOSA was formed and 100 old students joined. A move was then made to Southampton Row. By now the college had 110 students.
In 1909 Dr Russell was appointed principal, and pioneered the sandwich course. This meant students had a year or so of theory and then experienced work in industry, returning again to more theory. By 1914 many old students joined up and a crash course was started to aid the war effort. By 1919 some 350 had been in the services and 34 had died. In 1920 the fees had risen to 300 guineas.
By 1928 1000 students had joined the Old Students Association and in 1929 a 40th anniversary dinner was held. In 1939 a discussion with the governors resulted in a decision to evacuate the college to Thurlestone in Devon. A new principal, Dr WRC Coode-Adams, took over from Dr Russell. Faraday House took over the Links Hotel. Staff and students who were married lived in the hotel or in houses that had been taken over by the college.
In 1942 the college returned to Southampton Row. After the war Faraday House had difficulty in recruiting, students were lured to other colleges and universities by grants. In 1957 Mr GH Randolph Martin was appointed Principal. He had been a lecturer at the college since 1948. The college closed its doors in 1967 as losses were now running at £20,000 per year.
During its lifetime Faraday House produced a succession of engineers who attained the most senior positions in industry and electrical supply in many countries, and six old students have been president of the Institution of Electrical Engineers (now the IET).
The Old Students Association has a membership that is steadily growing older and shrinking as members die. The closure was inevitable without younger people coming forward to run it. The FHOSA will shut its doors finally after the Annual General Meeting in March 2010.
From knowledge to awareness and then to protection.
Yesterday, I dipped into the subject of electro-magnetic radiation. As hopefully made clear, I was writing in response to the film Beings of Frequency that was presented the previous day.
If you haven’t yet watched the film, then do. To be frank, the posts of yesterday and today are that much more valuable after the film has been watched.
In terms of reducing the effects of EMF, then a quick ‘Google’ search will bring up teems of websites. Many of them are selling filters, consultancy, EMF surveys, and more. While in no way impugning those services, my instinct is to be drawn to those websites and blogs motivated by the desire to be informational alone. At this stage of my research anyway.
There is a connection between electromagnetic fields and some cancers including leukemia
EMFDamage.com is online for these reasons: 1. To let you know there are serious health risks involved in living or working too close to power lines. I am certain the power line behind my home is the direct cause of my diagnosis of chronic lymphocytic leukemia. Electromagnetic fields (EMFs) have also been linked to other adult leukemias, childhood leukemia and brain cancer.
2. In addition to EMFs from power lines, you may also be exposed to unhealthy levels of EMFs from sources inside your home and workplace. These fields are easier to control and correct.
3. There are many ways to detect and measure the EMF levels at your home and at work.
4. You can reduce high EMF levels to reduce your risk of exposure.

So at this time, I don’t have the awareness of just what levels of EMF radiation we are exposed to here at home. But I’m going to undertake an investigation and, if we have a problem, work to a ‘cleaner’ house.
I shall be writing about this journey at regular intervals and explaining clearly why we did or did not do this or that.
What I would be delighted to publish on Learning from Dogs are accounts from others who have made similar journeys or know that they have been affected by EMF radiation. Do please drop me an email.
