Na sastanku eksperata tehnologije, zabave i dizajna (TED) u Oksfordu, koji je organizovan za razmenu ideja za buducnost, profesor Richard Dawkins smatra, izmedju ostalog, da je zivot verovatno sasvim uobicajena stvar u univerzumu, ali da je sam Univerzum veoma tezak za ljudski mozak da ga raspozna.
Covek zivi u tzv. nivou razmisljanja "srednjeg sveta" koji je sam stvorio.
Universe 'too queer' to grasp
By Jo Twist
BBC News science and technology reporter
Professor Dawkins believes life might be quite common within the universe
Scientist Professor Richard Dawkins has opened a global conference of big thinkers warning that our Universe may be just "too queer" to understand.
Professor Dawkins, the renowned Selfish Gene author from Oxford University, said we were living in a "middle world" reality that we have created.
Experts in design, technology, and entertainment have gathered in Oxford to share their ideas about our futures.
TED (Technology, Entertainment and Design) is already a top US event.
It is the first time the event, TED Global, has been held in Europe.
Species software
Professor Dawkins' opening talk, in a session called Meme Power, explored the ways in which humans invent their own realities to make sense of the infinitely complex worlds they are in; worlds made more complex by ideas such as quantum physics which is beyond most human understanding.
"Are there things about the Universe that will be forever beyond our grasp, in principle, ungraspable in any mind, however superior?" he asked.
Events of 7/7 and 9/11 remind us that we do not live in three different worlds. We live in one world
Ashraf Ghani, former Afghan finance minister
"Successive generations have come to terms with the increasing queerness of the Universe."
Each species, in fact, has a different "reality". They work with different "software" to make them feel comfortable, he suggested.
Because different species live in different models of the world, there was a discomforting variety of real worlds, he suggested.
"Middle world is like the narrow range of the electromagnetic spectrum that we see," he said.
"Middle world is the narrow range of reality that we judge to be normal as opposed to the queerness that we judge to be very small or very large."
He mused that perhaps children should be given computer games to play with that familiarise them with quantum physics concepts.
"It would make an interesting experiment," he told the BBC News website.
ET worlds
Our brains had evolved to help us survive within the scale and orders of magnitude within which we exist, said Professor Dawkins.
We think that rocks and crystals are solid when in fact they were made up mostly of spaces in between atoms, he argued.
This, he said, was just the way our brains thought about things in order to help us navigate our "middle sized" world - the medium scale environment - a world in which we cannot see individual atoms.
This idea meant that life was probably "quite common" in the Universe, Professor Dawkins said.
He concluded with the thought that if he could re-engineer his brain in any way he would make himself a genius mathematician.
He would also want to time travel to when dinosaurs roamed the Earth.
More serious focus
Developing world economist and businesswoman Jacqueline Novogratz brought Professor Dawkins' thinking into focus, arguing that we need to fully engage with "developing worlds" to move away from "them and us" thinking.
"The world is talking about global poverty and Africa in ways I have never seen in my life," she said.
"At the same time I have a fear that the victories of G8 will see that as our moral absolution. But that is chapter one; celebrate it, close it and recognise we need a chapter two - a 'how to'.
"The only way to end poverty is to build viable systems on the ground that can deliver services to the poor in ways that are sustainable," she said.
Former Afghan finance minister Ashraf Ghani added that globalisation was "on speed" and needed real private investment and opportunities to flourish.
"Events of 7/7 and 9/11 remind us that we do not live in three different worlds; we live in one world."
He criticised the West for being only concerned with design issues that affect them, and solving environmental problems for themselves.
"You are problem solvers but are not engaging in problems of corruption," he told TED Global delegates.
"You stay away from design for developments. Your designs are selfish; it is for your own immediate use.
"We need your imagination to be brought to bear on problems the way meme is supposed to. It is at the intersection of ideas that new ideas and breakthroughs occur."
More than 300 leading scientists, musicians, playwrights, as well as technology pioneers and future thinkers have gathered for the conference which runs from 12 to 15 July.

Pa naravno da ima.
Na primer, cim neko postavi pitanje: Sta je iza kraja Univerzuma, odmah znas da je u sebi stvorio sliku da sve mora da ima kraj, ali onako kako ga on zamislja: neki zid verovatno

Science and technology have powered huge leaps in understanding but our biggest challenges lie ahead.
The science of complexity is perhaps the greatest challenge of all, Astronomer Royal Sir Martin Rees believes.
The biggest conundrum is humanity and how we came to be, he told the Technology, Entertainment and Design (TED) conference in Oxford.
The cosmologist said that in the 21st Century science has changed the world faster than ever before and in many new ways.
"Our century is very, very special," said Professor Rees. "It is the first where humans can change themselves."
Advances such as drug implants may have fundamentally changed human beings profoundly already - the effects of which we could see this century.
We know more about our Universe, we know how stars are fuelled, how nuclei in atoms act together, and how galaxies are held together by dark matter - huge swarms of particles.
We can trace events back to the early stages of the Big Bang, but we still do not know what "banged", or even if there were multiple "bangs", said Prof Rees.
There is still a lot of "unfinished business" for humans, he said, particularly in understanding the theory that links the very large and the very small in our Universe - the theory that may lead to understand potentially different dimensions.
Quarter of a second in June
Prof Rees also had warnings for conference participants.
"Bio and cyber technologies are environmentally benign as they offer marvellous prospects, but they will have a dark side," he said.
"One technology may empower just one fanatic to trigger a global catastrophe.
"We have to accept the risks if we are going to enjoy the benefits of science," he said.
Prof Rees called on scientists and entrepreneurs to take on the responsibility to campaign and alert the rest of the world to both the risks and benefits. Earth, after all, has a long history ahead.

Whatever happens in this uniquely crucial century will resonate in the remote future and perhaps far beyond the Earth.
Sir Martin Rees
Even those in the field of evolutionary sciences are far from knowing how humanity will change.
Computer models can only go so far when we do not even fully understand how we came about on Earth in the first instance.
We have only existed, as far as we know, for a few billion years.
"If you represent the Earth's lifetime in a single year, the 21st Century would be a quarter of a second in June," said Prof Rees.
We are not even halfway through our allotted time on Earth before the Sun itself burns out.
"Any life and intelligence that exists then will be as different from us as we are to bacteria," he explained.
Our rate of population growth and our addiction to fossil fuels and consumption of resources only adds to the uncertainty about our future.
Life - but not as we know it
One man who is set on trying to unfold the complexity of life and how we are made up and came to be in order to understand our future is Craig Venter.
He was one of the masterminds behind the sequencing of the human genome - the genetic code that creates life.
His next big challenge is to create living, artificial organisms from a kit of genes, and he is well on his way. He says an artificial single cell organism is possible in two years.
"We sequenced 130 genomes this year. The rate of reading the genetic code has changed but we have barely scratched the surface," he told the conference.
Microbes make up over a half of all Earth's biomass. A mouthful of seawater accidentally swallowed sends millions of different bacteria into your gut.
To unravel the complexity of life on our planet in order to understand more about where humans come from, Dr Venter embarked on a round the world ocean voyage to take samples of seawater every 200 miles.
At every stop they found new species. At one location, one barrelful contained 1.3 million new genes and 50,000 new species.
To him, these genes are the design components of evolution, the "software that builds its own hardware".

The building blocks of life could help create new life forms
But evolution has only given us so many answers. "We need new methods to understand the biology out there. Only by trying to build it will we truly understand it," he says.
But the aims of his mission are even wider than that.
"We are optimistic we will have a new form of artificial life based on our knowledge of these existing genomes that provides knowledge to go forward to tackle environmental problems," he says.
"We know lots of different pathways and thousands of organisms that live off carbon dioxide can catch that back from the atmosphere."
That can then be converted to biopolymers and new products.
There are lots of pathways that can be engineered to convert methane into useful products too.
Future engineered species could be a source of food, energy, and could help regenerate damaged environments.
To Dr Venter, his venture is crucial to understanding our future.
He dismisses fears that if one can create artificial life once the code has been written, then this will open a Pandora's Box for those who want to play God or take us to an era of bioterror.
"Almost every major religion requires humans to try and improve society," he says.
One certainty in an uncertain world is clear to Prof Rees: "Whatever happens in this uniquely crucial century will resonate in the remote future and perhaps far beyond the Earth."

Humans have a "moral imperative" to open up space as a "new frontier", says X-Prize founder Peter Diamandis.
He also believes that within the next decade humans will find ubiquitous life on Mars and, in our lifetime, millions of people will be going into space.
Mr Diamandis addressed last week's Technology, Entertainment and Design (TED) conference in Oxford, held in Europe for the first time.
TED Global brings together scientists, designers and big thinkers to discuss how to make a better future for all.
High ambition
"If you think about space, everything we hold of value on this planet is in infinite supply there," Mr Diamandis explains.
"Earth is a crumb in a supermarket full of resources."
Inspired by the Apollo mission, it has been his ambition since childhood to take people into space, he says.
Mr Diamandis raised cash with help from the Ansari Foundation and others to create the Ansari X-Prize.
The prize rewarded the first non-government funded manned craft to reach the official 60km boundary of space twice in two weeks.
The $10m jackpot was won by aviation pioneer Burt Rutan's Scaled Composites team in 2004.
Its SpaceShipOne craft was the first vehicle to achieve the feat, and a modified version will now form the fleet for Richard Branson's Virgin Galactic space tourist service.
Both Mr Rutan and Mr Diamandis are passionate believers that humanity's future in space should be led by non-governmental missions.
Risk and reward
Only those missions can afford the great risks that are inherent in such early exploration.
"True breakthroughs require risks," thinks Mr Diamandis.
The cost of getting into orbit is the key to human survival, wealth and prosperity
Peter Diamandis
"The X-Prize showed that risk was OK. We should be allowed to take risk, and anyone who says we shouldn't should be put aside," he explains.
Those breakthroughs could happen in space; some could even provide world changing solutions for Earth, he believes.
Such risks, as evidenced by the recent false starts for the space shuttle, are proving increasingly difficult to justify for government-supported organisations, such as Nasa.
English Astronomer Royal, Sir Martin Rees, told the BBC News website that non-government missions were the only real option.
"My feeling is that with every advance in the miniaturisation of robotics, the practical case for sending humans into space is weakened," he said.
"Nasa-type projects are vastly expensive, partly because they are risk averse.
"So I think that any future for manned space exploration should be private sponsorship by people who are prepared to take the risk and cut corners," he argued.
He foresees many more probes doing the exploring for us, as satellite technology advances. This will help us understand our origins.
New frontiers
Indeed, one of the main themes at TED last week was that humanity has barely touched the tip of the iceberg in terms of its own evolution.
That goes for our knowledge of life outside of our "middle world" existence, as biologist Professor Richard Dawkins phrased it at the conference.
"We are young as a species," says Mr Diamandis. In terms of what our future in space would look like, he says: "We cannot conceive it".
"It is like asking the Europeans in the 1400s to think of life today. We will make decisions to change the very fabric of society.
"We may even reinvent society and the human form," he says.
If it sounds reminiscent of Christopher Columbus' colonialist ambitions, Mr Diamandis talks the talk that suggests it is.

Life on Mars could be waiting for us, says Mr Diamandis
"We are on the verge of the greatest exploration the human race has ever known," he says.
Frontiers are among our planets' scarcest resources, according to Mr Diamandis.
At frontiers, new decisions are made. People can rise to their full potential there because they are unhindered by social structure, he argues.
Of course, one motivation for claiming new frontiers and colonising them is power and wealth, which Mr Diamandis says drives the human desire for exploration.
"The cost of getting into orbit is the key to human survival, wealth and prosperity," he says.
The infinite resources that Mr Diamandis talks of include nickel-iron asteroids worth $20 trillion on the open Earth market.
But for now, Mr Diamandis is busy organising other X-Prizes to push humanity into taking risks, pushing scientific, medical, and technological advances.
X-Prizes for energy, genetic, environmental and medical development are all under development.
Geneticist Craig Venter has just joined the X-Prize board for a rapid genome prize.
His motivation here sounds altruistic.
"The most critical tool for solving humanity's challenges is a committed passionate human mind," says Mr Diamandis.

I sad neko kaze a sta je iza tog zida..... opet neki zid,pa prostor...pa... I ako tako pocnemo mozemo do preksutra 
Hteo sam samo da se nadovezem da je stvarno covekov um mali da sve to shvati!

Mali da shvati... Ili privremeno onesposobljen da razume... Moje misljenje je da imamo mnogo neverovatnih mogucnosti koje mozemo izvesti svojim mozgom, ali da nam je neko namerno poiskljucivao raznorazne opcije... Tako sebi objasnjavam pojave telekineze, levitiranje, telepatiju, sesta cula, ali i samospaljivanje, telesni magnetizam itd...
