Yesterday, the guest post published by Suzan from Romania touched many of you. In that guest post there was mention of the dog Joe.
Take Joe. Joe had been sold on Facebook and bought by dog-baiters, bitten so severely vets thought he would die. You’d think that’s turned him off to humans? But no! He was a beautiful 6yr-old Collie. He was awesome. He obeyed, loved and cherished us, giving cuddles, playing gently … I’ve never had such a beauty under my roof.
I also wrote that I would publish more today. Taken directly from Mrs Skeats’ blog.
ooOOoo
Joe died but his death is still carrying a message.
It’s 19th June 2014. Joe died 6 months ago on 23rd December 2013.
Joe was a 6 year old beautiful boy taken from us after only 10 months by a cruel twist .. an accident due to a lack of information .. so I started a mini campaign. And I’ve just read about another poor soul, a friend of a friend, having to wait to see if his dog will survive a stick injury. Heartbreaking.
Ok so writing about it channelled my grief but the whole thing goes beyond that.
What was to be thought a rare, freak accident turned out to be all too familiar to vets and families worldwide. What was thought to be a personal kick in the nuts turns out to be a case of ignorance that is most definitely not bliss.
I received hundreds of comments on my first post after Joe died. I received hundreds of facebook and twitter comments too. The current ‘WordPress’ views are at over 139,000 which is great, and yet not enough. Dogs are still being treated for nasty stick injuries, vets see a few each month. I can’t preach and say stop it, but I can let anyone and everyone who cares know what a potential danger stick throwing is: better than being totally ignorant of the risks.
What happened to Joe, and happens to dogs all over the world at a frighteningly too-often rate, was borne of ignorance, stupidity, even years of “that’s what we do with dogs”. We simply never thought about the consequences it could bring.
Historically, when man decided to have dogs as pets and not merely working companions (not all that long ago in the UK) chasing a stick was a favourite game. We’ve all seen the old adverts in faded yellows and reds with a boy, stick in hand and his faithful dog panting happily as he waits for the ‘toy’ to be thrown. Why should we think it’s dangerous? We see things like celebs on the One Show with their dog, happily throwing it a stick, or in videos…. Dogs and stick throwing seems synonomous.
These are but a few stories of reasons why we should try and change this ……………..
Please think twice before you throw a stick for your dog to chase.
In memory of a beautiful dog, whose life will not ever have been in vain, but will mean so much more if we save others from pain.
ooOOoo
Please follow those links that Suzan included and read the articles. The message is clear. If you are the owner of a dog or play with dogs, don’t ever throw them a stick to catch.
As with yesterday’s post, please share this as widely as you can.
Apologies again for today’s post being largely the republication of other essays but looking after our guests is, as it should be, taking first priority.
The first one was something I read on the Cliff Mass weather blogsite. It was a forecast as to which of the lower US 48 States would remain habitable. It opens:
Will the Pacific Northwest be a Climate Refuge Under Global Warming?
As global warming takes hold later in the century, where will be the best place in the lower 48 states to escape its worst effects?
A compelling case can be made that the Pacific Northwest will be one of the best places to live as the earth warms. A potential climate refuge.
and offers this conclusion:
So what conclusion does one inevitably reach by studying the IPCC reports, the U.S. Climate Assessment, and the climate literature?
The Northwest is the place to be during global warming.
Temperatures will rise more slowly than most of the nation due to the Pacific Ocean (see below)
We will have plenty of precipitation, although the amount falling as snow will decline (will fall as rain instead). But we can deal with that by building more reservoir and dam capacity (and some folks on the eastern slopes of the Cascades have proposed to do exactly that).
The Pacific Ocean will keep heat waves in check and we don’t get hurricanes.
Sea level rise is less of a problem for us due to our substantial terrain and the general elevation rise of our shorelines. Furthermore, some of our land is actually RISING relatively to the sea level because we are still recovering from the last ice age (the heavy ice sheets pushed the land down and now it is still rebounding).
There is no indication that our major storms…cyclone-based winds (like the Columbus Day Storm)… will increase under global warming.
Increased precipitation may produce more flooding, but that will be limited to river valleys and can be planned for with better river management and zoning.
The second item was this:
Antarctica’s Point of No Return
POTSDAM – Recent satellite observations have confirmed the accuracy of two independent computer simulations that show that the West Antarctic ice sheet has now entered a state of unstoppable collapse. The planet has entered a new era of irreversible consequences from climate change. The only question now is whether we will do enough to prevent similar developments elsewhere.
What the latest findings demonstrate is that crucial parts of the world’s climate system, though massive in size, are so fragile that they can be irremediably disrupted by human activity. It is inevitable that the warmer the world gets, the greater the risk that other parts of the Antarctic will reach a similar tipping point; in fact, we now know that the Wilkes Basin in East Antarctica, as big or even bigger than the ice sheet in the West, could be similarly vulnerable.
There are not many human activities whose impact can reasonably be predicted decades, centuries, or even millennia in advance. The fallout from nuclear waste is one; humans’ contribution to global warming through greenhouse-gas emissions from burning fossil fuels, and its impact on rising sea levels, is another.
Indeed, the latest Intergovernmental Panel on Climate Change (IPCC) report stated, in uncharacteristically strong terms, that the sea level is “virtually certain” to continue to rise in the coming centuries or millennia. Moreover, the greater our emissions, the higher the seas will rise.
Simply, because the quicker that the awareness of the critical challenges ahead becomes widespread knowledge, right around the world, the quicker that there will be political movements to change our relationship with our planet.
It’s never about not needing governments, it’s always about needing the right sort of governments.
Jealous wags: Dogs show envy is ‘primordial’ emotion
By Matt McGrath – Environment correspondent, BBC News
These border collies inspired the study on jealousy in dogs.
Jealousy is not just a human condition according to researchers, as it appears to be hard wired into the brains of dogs as well.
Scientists in California found that canines succumbed to the green eyed monster when their owners showed affection to a stuffed dog in tests.
Some experts have argued that jealousy requires complex cognition and is unique to people.
But the authors say their work shows it may also come in a more basic form.
These findings probably won’t be a major surprise to anyone who’s ever owned a dog, but the team say this is the first experimental test of jealous behaviours in man’s best friend.
Human jealousy is a complicated emotion, requiring a “social triangle” and usually arising when an interloper threatens an important relationship.
It is said to be the third leading cause of non-accidental homicide across cultures.
Building on research that shows that six month old infants display jealousy, the scientists studied 36 dogs in their homes and video recorded their actions when their owners displayed affection to a realistic-looking stuffed canine.
Faux fido
Over three quarters of the dogs were likely to push or touch the owner when they interacted with the decoy.
The envious mutts were more than three times as likely to do this for interactions with the stuffed dog compared to when their owners gave their attention to other objects including a book.
Around a third tried to get between the owner and the faux fido, while a quarter of the put-upon pooches snapped at the dummy dog.
“Our study suggests not only that dogs do engage in what appear to be jealous behaviours but also that they were seeking to break up the connection between the owner and a seeming rival,” said Prof Christine Harris from University of California in San Diego.
“We can’t really speak to the dogs’ subjective experiences, of course, but it looks as though they were motivated to protect an important social relationship.”
The researchers believe that the dogs understood that the stuffed dog was real. The authors cite the fact that 86% of the dogs sniffed the toy’s rear end, during and after the experiment.
Jealousy, according to the authors, may have evolved in species that have multiple dependent young that concurrently compete for food and affection.
The argue that jealousy might give an advantage to a young animal that is not only alert to the interactions between its siblings and its parents but is motivated to intervene.
“Many people have assumed that jealousy is a social construction of human beings – or that it’s an emotion specifically tied to sexual and romantic relationships,” said Prof Harris.
“Our results challenge these ideas, showing that animals besides ourselves display strong distress whenever a rival usurps a loved one’s affection.”
Yesterday, I published a post under the title of Just to focus our minds. It featured a chart that demonstrated how long Planet Earth would take to ‘recover’ if the human race disappeared today.
Why today’s post seemed a perfect companion was because it explores how we could think better. For if the human race doesn’t quickly find a way to think better, then that aforementioned chart may not be such an academic abstract after all.
The post is more or less a copy of what appeared on the Big Think blogsite, a site I have been following for some time now.

Want to Make a Difference in the World? Think Small
Stephen Dubner
Ambition can work against you by leading you to set unrealistic and overwhelming goals. Want to make a difference in the world? Think small. It’s much less complicated, you’ll have easier access to the data that you’ll need. Most importantly, you will preserve one of your most precious resources: optimism.
Having the will to attack an issue at its root—from launching a socially conscious business to demanding more green spaces in your neighborhood—requires energy and enthusiasm to see the project through. By being less ambitious in your plans you’re more likely to stick with them and be successful.
Besides, when you first developed your problem-solving skills you were small—a child. Stephen Dubner, the co-author, with economist Steven Levitt, of Freakonomics and Think Like a Freak, wants you to go back to that way of thinking:
One of the most powerful pieces of thinking like a child that we argue is thinking small. So I realize that this runs exactly counter to the philosophy of the arena in which I’m appearing which is thinking big, Big Think, but our argument is this. Big problems are by their nature really hard to solve for a variety of reasons. One is they’re large and therefore they include a lot of people and therefore they include a lot of crossed and often mangled and perverse incentives. But also a big problem – when you think about a big problem like education reform. You’re dealing with an institution or set of institutions that have gotten to where they’ve gotten to this many, many years of calcification and also accidents of history. What I mean by that is things have gotten the way they’ve gotten because of a lot of things a few people did many, many years ago and traditions were carried on.
Want to break those traditions and build something new and forward-thinking? Then curb your ambition. Start to look at the world again with the eyes of a child.
Stephen Dubner talks about [that YouTube link reveals the transcript of the talk. PH] the importance of thinking small in order to tackle some of the world’s biggest problems piece by piece. Dubner is the co-author of Think Like a Freak
ooOOoo
Stephen Dubner and economist Steven Levitt co-authored the book Freakonomics. If you are interested, the Freakonomics website is here.
Just to put this into context, if you watched the George Monbiot speech that was the highlight of my post last Tuesday, The Goon Show, you might well have been forgiven for wondering if these are starting to feel like the end-times for species homo sapiens.
Almost perfectly on cue, on Monday, John Hurlburt down in Payson, AZ., sent me the following. It does make one think!
Time Required for the Earth to Heal if the Human Race Disappeared Today
Time Required for the Earth to Heal if the Human Race Disappeared Today.
(While John over the telephone read out the URL that was the source of this ‘chart’, I was unable to link to it. Thus apologies for not recognising the author.)
Then if you are up for more of the same theme, here’s a film that will ‘entertain’ you.
Published on Sep 2, 2012
What will happen when humans disappear from the face of the Earth? This movie will certain make you think about the impact we have made on this beautiful planet. But when humans are gone… Earth does continue.
Imagine if one minute from now, every single person on Earth disappeared. All 6.6 billion of us. What would happen to the world without humans?
How long would it be before our nuclear power plants erupted, skyscrapers crumbled and satellites dropped from the sky?
What would become of the household pets and farm animals? And could an ecosystem plagued with years of pollution ever recover?
Similar to the History Channel’s special Life After People (recommended), Aftermath features what scientists and others speculate the earth, animal life, and plant life might be like if humanity no longer existed, as well as the effect that humanity’s disappearance would have on the artefacts of civilisation.

As I have been intimating previously, today is the start of my mother from London visiting us here in Oregon. Thus, as one would expect, time for blogging is going to be restricted. Then in a week’s time, we are also joined by my sister, Elizabeth, who lives in Tokyo. So, dear reader, you will understand if there is a deficit of creative writing, assuming you find some of it creative, why that is.
Thus today, I’m leaning heavily on a recent item I read on the EarthSky blogsite. It’s all about pronking! Yes, I hadn’t come across the word before.
ooOOoo
Does your dog pronk?
Among wild animals, pronking may be a way of avoiding predators. But when you see an animal pronk, you can’t but think it’s leaping for joy.
Alpacas, gazelles, some deer and baby lambs are all known to pronk. That is, they leap into the air as if leaping for joy, lifting all four feet off the ground at once. The fact that – in some species like sheep – young animals do it more than older ones does suggest playfulness. But, among wild animals, pronking may be a way of avoiding predators. It means something like, “Hey, I’m very fit so don’t bother chasing me.”
But how about dogs? I didn’t find much online discussion about true dog-pronking, although many of us, at one time or another, may have seen our dog leaping for joy. I recall my own dog Snoop (rest his soul) released from the car in a South Dakota meadow, leaping and running like crazy through the long grass for maybe 20 minutes, until we called him back. It was one of the most joyful things I’ve ever seen, and definitely one of my best memories of Snoop.
So enjoy the videos below. And, by the way, although it is a survival strategy for some, the very word pronk comes from an Afrikaans verb pronk-, which means show off or strut. It has the same linguistic derivation as our English verb prance.
“Pronking” seems to occur when an animal gets excited and jumps around his field, leaving the ground with all four feet simultaneousl, almost as though he had springs attached to his feet..Often these jumps can be high in the air.No-one really knows why llamas pronk. Certainly it is the response to some sort of excitement or disturbance. It is often infectious; sometimes my entire herd will take off. I am told that it isn’t only llamas but sheep and goats. Those of you old enough to remember BBC’s Magic Roundabout may well recall that Zebedee was a “pronker”. We never had a telly as kids, but I believe Zebedee was a dog (??).
Okay, well, maybe some sheep and wild animals like this young springbok – in Etosha National Park, Namibia – are the only true pronkers. Maybe true pronking has to have the downward-pointing head and stiff-leggedness. But if you ever see your dog do what the dogs in these videos do … you’ll feel happy. Image via Wikipedia.
Bottom line: Among wild animals, pronking seems to be a way of avoiding predators. But when you see an animal pronk, you can’t but think it’s leaping for joy.
ooOOoo
So there you go. Don’t say that Learning from Dogs doesn’t teach you some new words from time to time!
Thus it was rather fun to come across, more or less by chance, an essay from the Perimeter Institute for Theoretical Physics under the title of Is The Universe A Bubble? The essay describes how Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. It opens:
Never mind the big bang; in the beginning was the vacuum. The vacuum simmered with energy (variously called dark energy, vacuum energy, the inflation field, or the Higgs field). Like water in a pot, this high energy began to evaporate – bubbles formed.
Each bubble contained another vacuum, whose energy was lower, but still not nothing. This energy drove the bubbles to expand. Inevitably, some bubbles bumped into each other. It’s possible some produced secondary bubbles. Maybe the bubbles were rare and far apart; maybe they were packed close as foam.
But here’s the thing: each of these bubbles was a universe. In this picture, our universe is one bubble in a frothy sea of bubble universes.
That’s the multiverse hypothesis in a bubbly nutshell.
It’s not a bad story. It is, as scientists say, physically motivated – not just made up, but rather arising from what we think we know about cosmic inflation.
Cosmic inflation isn’t universally accepted – most cyclical models of the universe reject the idea. Nevertheless, inflation is a leading theory of the universe’s very early development, and there is some observational evidence to support it.
It includes this interesting video:
and concludes, thus:
Meanwhile, the team is at work figuring out what other kinds of evidence a bubble collision might leave behind. It’s the first time, the team writes in their paper, that anyone has produced a direct quantitative set of predictions for the observable signatures of bubble collisions. And though none of those signatures has so far been found, some of them are possible to look for.
The real significance of this work is as a proof of principle: it shows that the multiverse can be testable. In other words, if we are living in a bubble universe, we might actually be able to tell.

So that’s blown the dust off your Saturday brains! You can go and hug your dog now! 🙂
The second, and last, episode of the BBC Clouds Lab programme offers an intriguing message.
On Monday, I published a post under the title of The clouds above us. The second episode demonstrated that even in atmospheric conditions of near vacuum, intense cold and very low humidity, conditions that would kill a human in seconds, there was microscopic bacteriological material to be found.
Exploring the troposphere
The troposphere is a turbulent layer of air that begins at the Earth’s surface and ranges from 23,000-65,000 feet above sea level, depending on the latitude, season and the time of day. Its name originates from the Greek word tropos, meaning change. It’s now known that bacteria actually exists in clouds and scientists believe that it plays a significant part in the creation of rain but little is known about life higher up. Microbiologist Dr Chris Van Tulleken has discovered that living bacteria can exist well above 10,000ft in a hostile environment with low pressure, increased UV radiation, freezing temperatures, high winds and no oxygen or water.
What I took away from watching the programme was that the minimum conditions necessary for living bacteria were far more harsh than one might expect. In other words, finding living bacteria in other solar systems might not be such a science-fiction idea.
With that in mind, I’m republishing an essay that Patrice Ayme wrote in 2013. I’m grateful for his permission to so do.

40 Billion Earths? Yes & No.
Up to twenty years ago, a reasonable opinion among scientists was that there might be just one solar system. Ours. Scientists like to project gravitas; having little green men all over didn’t look serious.
However, studying delicately the lights of stars, how they vary, how they doppler-shift, more than 1,000 planets have been found. Solar systems seem ubiquitous. Astronomers reported in 2013 that there could be as many as 40 billion habitable Earth-size planets in the galaxy. However, consider this:
Centaurus A: Lobes Of Tremendous Black Hole Explosion Fully Visible.
Yes, that’s the center of a galaxy, and it has experienced a galactic size explosion from its central black hole.
One out of every five sun-like stars in our galaxy has a planet the size of Earth circling it in the Goldilocks zone, it seems — not too hot, not too cold — with surface temperatures compatible with liquid water. Yet, we have a monster black hole at the center of our giant galaxy, just like the one exploding above.
The Milky Way’s black hole is called Sagittarius A*. It exploded last two million years ago. Early Homo Erectus, down south, saw it. The furious lobes of the explosion are still spreading out, hundreds of thousands of light years away.
We are talking here about explosions potentially stronger than the strongest supernova by many orders of magnitude (depending upon the size of what’s falling into Sagittarius. By the way, a cloud is just heading that way).
Such galactic drama has a potential impact on the presence of advanced life. The richer the galaxy gets in various feature the situation looks, the harder it looks to compute the probability of advanced life.
The profusion of habitable planets is all the more remarkable, as the primitive methods used so far require the planet to pass between us and its star.
(The research, started on the ground in Europe, expanded with dedicated satellites, the French Corot and NASA’s Kepler spacecraft.). Sun-like stars are “yellow dwarves”. They live ten billion years.
From that, confusing “habitable” and “inhabitated”, the New York Times deduced: “The known odds of something — or someone — living far, far away from Earth improved beyond astronomers’ boldest dreams on Monday. “
However, it’s not that simple.
Primitive bacterial life is probably frequent. However advanced life (animals) is probably very rare, as many are the potential catastrophes. And one needs billions of years to go from primitive life to animals.
After life forms making oxygen on Earth appeared, the atmosphere went from reducing (full of strong greenhouse methane) to oxidizing (full of oxygen). As methane mostly disappeared, so did the greenhouse. Earth froze, all the way down to the equator:
When Snowball Earth Nearly Killed Life.
Yet volcanoes kept on belching CO2 through the ice. That CO2 built up above the ice, caused a strong greenhouse, and the ice melted. Life had survived. Mighty volcanism has saved the Earth, just in time.
That “snowball Earth” catastrophe repeated a few times before the Earth oxygen based system became stable. Catastrophe had been engaged, several times, but the disappearance of oxygen creating life forms had been avoided, just barely.
Many are the other catastrophes we have become aware of, that could wipe out advanced life: proximal supernovas or gamma ray explosions.
Cataclysmic eruption of the central galactic black hole happen frequently. The lobes from the last one are still visible, perpendicularly high off the galactic plane. The radiation is still making the Magellanic Stream simmer, 200,000 light years away. Such explosions have got to have sterilized a good part of the galaxy.
In 2014 when part of the huge gas cloud known as G2 falls into Sagittarius A*, we will learn better how inhospitable the central galaxy is for advanced life.
Many of the star systems revealed out there have surprising feature: heavy planets (“super Jupiters“) grazing their own stars. It’s unlikely those giants were formed where they are. They probably swept their entire systems, destroying all the rocky planets in their giant way. We don’t understand these cataclysmic dynamics, but they seem frequent.
Solar energy received on Earth fluctuated and changed a lot, maybe from one (long ago) to four (now). But, as it turned out just so that Earthly life could survive. Also the inner nuclear reactor with its convective magma and tectonic plates was able to keep the carbon dioxide up in the air, just so.
The Goldilocks zones astronomers presently consider seem to be all too large to allow life to evolve over billions of years. They have to be much narrower and not just with red dwarves (the most frequent and long living stars).
One of our Goldilocks, Mars, started well, but lost its CO2 and became too cold. The other Goldilocks, Venus, suffered the opposite major technical malfunction: a runaway CO2 greenhouse.
Mars’ axis of rotation tilts on the solar system’s plane enormously: by 60 degrees, over millions of years. So Mars experiences considerable climatic variations over the eons, as it goes through slow super winters and super summers (it’s imaginable that, as the poles melt, Mars is much more habitable during super summers; thus life underground, hibernating is also imaginable there).
Earth’s Moon prevents this sort of crazy hyper seasons. While, differently from Venus, Earth rotates at reasonable clip, homogenizing the temperatures. Venus takes 243 days to rotate.
It is startling that, of the four inner and only rocky planets, just one, Earth has a rotation compatible with the long term evolution of advanced life.
Earth has also two striking characteristics: it has a very large moon that store much of the angular momentum of the Earth-Moon system. Without Moon, the Earth would rotate on itself once every 8 hours (after 5 billion years of braking by Solar tides).
The Moon used to hover at least ten times closer than now, when earth’s days were at most 6 hours long.
The tidal force is the difference between gravitational attraction in two closely separated places, so it’s the differential of said attraction (which is proportional to 1/dd; d being the distance). Hence the tidal force is inversely proportional to the cube of the distance.
Thus on early Earth tides a kilometer high were common, washing back and forth every three hours. a hyper super tsunami every three hours, going deep inside the continents. Not exactly conditions you expect all over the universe.
Hence biological material fabricated on the continental margins in shallow pools would get mixed with the oceans readily. That would guarantee accelerated launch of life (and indeed we know life started on Earth very fast).
The theory of formation of the Moon is wobbly (recent detailed computations of the simplest impact theory do not work). All we know for sure, thanks to the Moon rocks from Apollo, is that the Moon is made of Earth mantle materials.
Somehow the two planets split in two. (Fission. Get it? It maybe a hint.)
Another thing we know for sure is that Earth has, at its core, a giant nuclear fission reactor, keeping Earth’s core hotter than the surface of the sun. An unimaginable liquid ocean of liquid iron deep down inside below our feet undergoes iron weather. Hell itself, the old fashion way, pales in comparison.
Could the Moon and the giant nuclear reactor have the same origin? This is my provocative question of the day. The Moon, our life giver, could well have formed from giant nuclear explosions, of another of our life givers, what became the nuke at the core. I can already hear herds of ecologists yelp in the distance. I present the facts, you pseudo-ecologists don’t decide upon them. It’s clear that nuclear fission is not in Drake equation: if nothing else, it’s too politically incorrect.
All the preceding makes this clear:
Many are the inhabitable planets, yet few will be inhabitated by serious denizens.
This means that the cosmos is all for our taking. The only question is how to get there. The closest stars in the Proxima, Beta and Alpha Centauri system are not attainable, for a human crew, with existing technology.
However, if we mastered clean colossal energy production, of the order of the entire present energy production of humanity, we could get a colony there (only presently imaginable technology would be fusion).
Giordano Bruno, professor, astronomer, and priest suggested that there were many other inhabitated systems around the stars. That insult against Islam meant Christianity was punished the hard way: the Vatican, the famous terrorist organization of god crazies, put a device in Giordano’s mouth that pierced his palate, and having made sure that way that he could not tell the truth, the terrorists then burned him alive. After seven years of torture.
The horror of truth was unbearable to theo-plutocrats.
Now we face something even worse: everywhere out there is very primitive life. It is likely gracing 40 billion worlds. But, if one has to duplicate the succession of miracles and improbabilities that made Earth, to earn advanced life, it may be just here that civilization ever rose to contemplate them.
Congratulations to India for launching yesterday a mission to Mars ostensibly to find out if there is life there (by finding CH4; while life is presently unlikely, Mars has much to teach, including whether it started there). That’s the spirit!
The spirit is to have minds go where even imagination itself did not go before.
If we sit back, and look at the universe we have now, from Dark Matter, to Dark Energy, to Sagittarius, to the nuclear reactor below, to billions of Earths, to a strange Higgs, to Non Aristotelian logic, we see a wealth, an opulence of possibilities inconceivable twenty years ago.
Progress is not just about doing better what was done yesterday. It’s also about previously inconceivable blossoms of entirely new mental universes.
A team of scientists take to the skies in one of the world’s largest airships, for a unique exploration of Earth’s most precious and mysterious environment – the atmosphere.
In an example of what might be called a massive change of topic from yesterday’s post on Integrity and democracy, today’s offering to you, dear reader, is about the magnificent atmosphere upon which we all depend.
Here’s a clue.
Sunrise to our North-East at a little after 7am on Sunday, 13th July, 2014.
Every Breath We Take: Understanding Our Atmosphere
The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. But how did we come to understand what air is made of? How did we come to know that this invisible stuff around us contains anything at all?
Gabrielle Walker tells the remarkable story of the quest to understand the air. It’s a tale of heroes and underdogs, chance encounters and sheer blind luck that spans the entire history of science. It began as a simple desire to further our knowledge of the natural world, but it ended up uncovering raw materials that have shaped our modern world, unravelling the secrets of our own physiology and revealing why we are here at all.
There is much more to explore on the website, including this trailer to the programme.
Oh, here’s another ‘clue’ from Oregon.
Same morning, same sunrise.
The presenter of the BBC series is Felicity Aston who writes on her BBC Blog:
I joined Operation Cloud Lab: Secrets Of The Skies as the expedition leader and also as a meteorologist.
The plan was to fly from Florida to California, looking at the science of the skies.
But as well as scientists, there were plenty of other people on the team including three pilots, a ground crew of 14 that followed the airship by road and a full production team including two camera crews. Not everyone could be on board at once – the airship would never have got off the ground!
But I was really fortunate to spend a lot of time on board and flew most of the way across the continent.
Exploring in three dimensions rather than being limited to making observations from the ground was a revelation to me.
The clouds in the tropics around the Gulf of Mexico are huge, and being in the sky with them really brought home the vast scale of the forces at work.
Towering cumulus cloud in Florida.
We were able to travel over, under and through these monsters, revealing that clouds are about as far from the popular image of light and fluffy floating puffs of cotton wool as you can get! They are dense and heavy and full of destructive energy.
I remember looking down at the cloud layer from a plane as a child, and daydreaming about exploring this new world of unknown places, so I was very excited the first time we flew straight through a cloud.
I leaned out of the airship as far as I dared into the heart of a cloud and found that it was a dark, damp mass of floating fog (of course!) – no mysterious worlds – my childhood fantasies were crushed!
There’s more to read on her blog as well as some stupendous photographs of clouds.
So if this gives you a thrill then don’t delay in watching the full-length Episode One on YouTube before it gets taken down. (Warning: if you watch the opening first few minutes you will be hooked for the full hour!)
A republication of an essay on the history of dogs.
Dr. George Johnson
For some time I have been aware of an essay authored by Dr. George Johnson under his On Scienceseries page umbrella. As that page explains:
ON SCIENCE is a weekly science column written by me (George Johnson), published initially in the St. Louis Post Dispatch, and now in the online newspaper St. Louis Beacon (stlbeacon.org). For over 30 years I taught biology to college students at Washington University. For the last decade of these years, I taught a freshman course that introduced nonscience majors to current issues where science plays a key role, issues such as AIDS, the environment, cloning, genetic engineering, and evolution.
The course was intended to give them the tools to think about these issues as citizens and voters. I write my column as a way of teaching the general public about these same issues.
Most people are very interested in science, but put off by the terminology. When you don’t know what the words mean, it’s easy to slip into thinking that the matter is difficult, when actually the ideas are simple, easy to grasp, and fun to consider. It’s the terms that get in the way, that stand as a wall between citizens and science.
It is the intent of my column to turn those walls into windows, so that readers can peer in and join the fun. Analogies are my tool. In each column I look for simple analogies that relate the matter at hand to things we all know. As science, analogies are not exact, but I do not count myself compromised. Analogies trade precision for clarity. If I do my job right, the key idea is not compromised by the analogy I use to explain it, but rather revealed.
Anyway, the particular essay that I was very interested in was, unsurprisingly, one about the history of the domestic dog.
I wrote Dr. Johnson asking for permission to publish his essay here on Learning from Dogs and promptly received such permission. Indeed, better than that, here is his reply email:
By all means, but please cite a revised version of the article (in ESSENTIALS OF THE LIVING WORLD, 5e, George B Johnson, McGraw Hill Publ., 2015). It is somewhat shorter, but more up-to-date. I enclose a copy of the relevant page below.
