Apocalypses

Imatge
Current year (2012) must be last year. Mayas predicted the end of the time at December 21th but the day passthrough and it didn’t pass anything. In fact humanity has many challenges which it’s playing its future, however there was the same challenges in the day 22th to 20th and in the same severity.   Apocalypse is the Christian Book that relates the end of the world. This Book isn’t the only relate that talks about of this theme. Exist a great number of prophecies, cosmologies or natural signs that predict the finish of the time.  Some of these are allegoric histories without temporal references except they always happen in a far future. Others suggest a kind of terms without explicit date which are allowing a legion of fortunetellers, wizards, gurus and charlatans to mark dates. In Doomsdays (The Economist Dec/12) can see some dates of possible end of World, I would observe that all rebased dates was failing. People have a great fascination for the destruction and catastrophe

A little Christmas Tale

Imatge
Catalan greeting It’s usual to these holydays to make a stop of our day to day witch we reflect about where we are, where we go and where we come. Often this reflection is masked by the usual noise that accompanies these dates: to buy gifts, write Christmas cards, preparing meals… but everyone will take a brief moment to make it, or the moment will take you when you least expect. I never like these days.  May be the trivialization or how depressing it can be to become, I use to try avoid Christmas dates. But this year I’m beginning to write a blog and I think that a formal “Merry Christmas” is very sad, so I have written a little Christmas count that I expect to like you.   A long time ago it appeared a new star that began to shine above the rest. People marveled at this great wonder but nobody knew the reason for this. But four Wizards who lived in orient understood that was its mean: Everybody Knows and is prophecy, who will take away the sins, will be born in a stable.   No

Doha, the time is over

Imatge
Doha hasn’t been a success. Connie Hedegaard has a contrary opinion on this issue, as she expose in her paper Why the Doha climate conference was a success (the Guardian 12/14/12), and her voice is much more authoritative that mine. But in my humble opinion, Doha and the before last conferences of climate, have not covered the minimum and the expectations.   She talks about the success in terms of a steep more on the path to achieve the goal. She shows a checklist of objectives and achievements; she laments the slow progress and she hopes that it can fulfill the 2015 agenda. I believe that conference has made advances but they are sufficient. Humans work bat the concept “Time”, this defect produces most of the errors that humanity makes and we have done historically. Like the tortoise and the hare of the story, climate doesn’t stop while we continue with our problems unrelated to the advancement of events. Yes we have made a steep but the climate change between our steeps make t

All argues aren’t valid

Imatge
Today we can hear many voices calling for greater strength by the scientific community about climate change and its consequences. This call is due to complete paralysis of government in this question. Weather changes and we can see it day by day and we just see how it applies some paid, later and bat. In other hand economic powers pay scientific or pseudo-scientific informs that denies the climate change or justified by an improvement in changing environmental conditions. In this respect we find a paper published in The Guardian: Light pollution can have positive effects on wildlife, study shows (Jessica Aldred 28/11/12); where expose those artificial light benefice migratory birds.   I believe that migratory birds life better after arrived of electrical light and its perpetual day, but how many species suffer the inconvenience of living without night. That some birds can hunt at night like day precludes other species that need the darkness can do, for example the owl. Other pr

Coffee

Imatge
Black as sin  bitter defeat as  short a sigh  and hot as hell As a good coffee man defines thought it would be a good coffee. But in this question there are so many opinions as people. From what we could swim in the bowl until the sugar overflows over, in the middle we have who don’t want sugar coffee and who which would throw the coffee into the sugar box and then try to ingest content. But no matter million liters of it are consuming daily and in global terms this is the most famous tisane and It’s consuming throughout the world. This drink is who moves Occident (aided by other infusions like tea). It has a stimulant that helps the daily movement, and makes Western society can maintain its frenetic beat. His omnipresence everywhere, thanks to the vending machines, makes it one of the most common addictions around the world. Who has not had an impasse and eventually  gone to take a coffee. For a lot of willpower and ability weakens the forces when the body begins

Infinite growth

Imatge
Since Edwin Hubble showed that the expansion of the universe in 1929, although in fact it was Georges Lemaître in 1927 who first discovered, the dream of unlimited growth was a reality. The twentieth century became the space age, humans will be covering interplanetary distances, we will travel to the stars and we colonize the universe as the times of the great discoveries of the modern age, it will become the human golden future. In the 60s of the last century we had certainly that we will be exploring Mars and the existence of human colonies in Moon or orbit around earth at the end of the century. But we arrived at 2012 and there is only a space station orbiting the earth with a population of three astronauts. The space that we have it’s too far for humans. We dream in Martian exploration but we don’t dare go to the moon that is a challenge three or four degree of magnitude less difficult than a trip to Mars. As ever our perceptions have betrayed us and what we assumed th

Human heat

Imatge
We are in an interior room where natural light doesn’t come in. Generalization of electricity has meant that we solve this problem just by pressing a switch usually placed near the entrance that ignites an artificial source of light (i.e. a strip light). This source illuminates walls and objects contained in the room, and the same in all directions make this reflection, a fraction of reflected light reaching our eyes just allowing us to create an image of what surrounds us. But if we press the switch other time instantly becomes dark. The second action is natural because we daily experience proves this, but someone has stopped to think where the light go. It may seem a trivial question because if we turned off the light that is over, but it is not. Energy isn’t created nor destroyed, the room that we were hasn’t opening up so all the energy that enters the electrical wires trapped inside the room, yet we see the light disappears. Really this is absorbed by the walls, and it joins ener

Ignore the evidence

I am just a poor boy Though my story's seldom told I have squandered my resistance For a pocket full of mumbles such are promises All lies and jests Still a man hears what he wants to hear And disregards the rest                                       The boxer (Simon & Garfunkel) This is a famous song by Simon & Garfunkel (1969) which tells the first person story of a pariah. This first verse summarizes what has been his life: a series of deceptions to exhaustion, but also acknowledges his guilt is to understand just what suited him. In the paper "Sometimes a nudge from the government is just not enough" ( 07/06/12 ) Lord Krebs asked even campaigns promoting environmental awareness and good habits like quitting smoking and not exceed the weight advisable, why not obtain the expected results. The writer talked about inducing behaviors to overcome inertia, but others simply would apply coercive measures like bans, fines and social marginalization. These seconds

The day after Tomorrow

Imatge
This is the title of a 2004 film that related about the sudden arrival of the fifth Quaternary glaciation. The film has the same rigor that 2012 film: none; but unlike 2012 where it exposed an improbable situation even with the entry conditions of film, the day after it presents a realistic situation and the probable events, while exaggerated developing the script and the plot is pathos. Like every movie has a happy ending entirely unrealistic because the reduction of a third of the area who have to live half of the 7,000 million inhabitants probably end up with a war for the remaining land (in this context Is it sure that Mexico will be able to contain 150 million evacuees at the border, as shown in the film, until you write off debt before wile evacuation is doing by second largest and technical army in the world? and why we do it extends to China Russia, UK, France, Japan ...). I don’t what to speak about the movie but the real possibility of a new ice age that would change in

Feedback

Today more or less everyone has heard about climate change and the greenhouse effect. Another thing is that everyone really understands the same when they talk about these two concepts. When the same academic don’t agree on many aspects of the climate, it’s unrealistic to think that the general population has a unique view of the events that affect the current and future climate. Everything concepts and Climate Change and Greenhouse are two concepts that attempt to describe unambiguous easily. Climate Change is exactly that means its name: the climate change is only the pass-through of a particular climate state in other different. It is a very common situation that has happened several times in the life of our planet and for some historical times. It is a traumatic event for a living beings but characteristic of the weather luckily frequency is small compared to the lives of most of these beings, allow periods with calm. The Greenhouse is a quality of our atmosphere which allowed lif

Method and imagination

Today computers are extending the entire world. Their size and potencies are very assorted so like their utilities. Computers have come in our lives that work for us. Without their intervention we never have arrived at technological and knowledge level that we have today, level unimaginable before, even science fiction literature. The unstopping growing of potencies helps us to confront a lot of problems with awkward solution that we can do methodic solutions when the problem didn’t allow analytic once.  Method is the best thing that you can do when the problem has a knowing solution and the method is just for it. Method is fast and sure but it’s restricted at the specific problem that it thinks. Sometimes we can extrapolate the method at the similar problem even there are methods that we apply at all the field of problems. But more times we are tempted to take the short lane and to apply methods that we know, at all the problems that we can find, even when the problem has specific me

The finish of North Pole ice can provoke a new ice age

Imatge
The paper publicized in Nature “ Western Arctic Ocean freshwater storage increased by wind-driven spin-up of the Beaufort Gyre ” (Katharine A. Giles, et al. 01/2012), authors talked about a great bulge with 8.000 Km3 of fresh water that is caching between ice and saline water. In the last years its size tends to grow, and the phenomenon is linked to climate change. The origin of fresh water is the water of the rivers that flow into Artic Sea and snow of ice layer thawed. This water doesn’t blend with the Artic water and its size has a fluctuated seasonal. Why exits a bulge fresh water and does it blend with Artic water? I can explain it. If you take fresh water and you put into salt, salt dissolves quickly; but if you take fresh and saline water and both put into glass slowly both liquids continue without blended, similar water and oil. This behavior is caused by different density of them also if we stir them water blended. In the sea happens the same but in surface there are win

How will workers life after total robotic industry?

Terminator returns from future that machines were won the war with humans. The history talk about a rebellion of robots with superior intelligent and they arrived at the conclusion that humans were redundant. NY Times in this article related a history about industry without workers and there are only the first because it will extends to all the world even china and emergent nations. The mechanization was come the liberation of heavy works to humanity. And its extension was been a point of inflexion with a global health and life quality. On the other hand the progressive advance of mechanization reduces the number of workers in manual jobs too. This reduction is supplied by creation of new kind of jobs, but it never is so quickly for compensation the destruction. The results of them some people are leaving off the system in the process. The logical evolution will come to total mechanization of industrial work. But not only because administrative work has mechanized too; maintenance, d

Hot today doesn’t necessary mean Cretaceous Climate tomorrow

We are now in one of the hotter summer until we have data, and affect all north hemisphere. The extreme climatic episodes has augmented in last years and it’s a prove the begin of climate change.  The most relevant effect is the growing of mean planetary temperature associate at the growing of CO 2 concentration. Both grows are simultaneous and the most preoccupant of them is that is making with exponential form. But can we affirm that the future weather will be the same of the Cretaceous age in a few years? The answer is not trivial. The growing of greenhouse gasses help to grow the atmosphere temperature, and the growing of temperature augment the concentration of this gasses, this fact is naming Feedback. Feedback is the main mechanism to guide the atmospheric processes. There are same studies that show the correlation of CO 2 concentration and temperature, and there are numeric models that demonstrate this correlation. This thing don’t mean that we had burned a lot of fossil fue

The drop that makes a glass overflows

If you fill a glass until the top and the last section we do drop to drop, we reach a point where a drop enters the glass begins to overflow. We can consider that the penultimate drop completed volume of the glass and last drop did not fit and so it fell by the side. So just get out there would expect a drop, but in reality much more water overflows. This behavior is caused by the surface tension of the liquid that links the surface preventing it from breaking, thus the last drops before overflow don't fit but tension doesn't let water to fall by side. When it starts to overflow? So when the weight of the liquid is higher than the tension, the surface loses its mechanical consistency and breaks, it let out all the excess liquid. There are other metastable situations that after passing the threshold of stability, under certain conditions so close to threshold, it remains stable until they were disturbed or too move away to threshold. The instantaneous vaporization of water’s gl

Risk premium, something more

Not everyone to squander one's money these days of debauchery. There is a growing tendency by economists and politicians to scold and blame current people for all the evils existing, and thus justify a number of unfair measures against the population. We talk about how they mistreat the citizens standing with the excuse that the "blame" is of their, and while no one touches the rich and their servants, politicians and economists. This necessary collaborators both in action as  omission, neither warned nor acted when it was time, the few things they did just helped ruin the situation more and continue they are doing. Now we find that the punishment falls both as right as guilty. Even more dramatic is the injustice of all, those who have saved and have not followed the mainstream and the general festival, now are suffering like the others. It's like the fable of the ant after working all summer, in winter it was expropriated the nest and left in the street next to the
