Learning the Immune System by Playing a Game

The Federation of American Scientists (FAS) has released a computer game called Immune Attack.

ABCNews asks: Are Video Games the New Textbooks?
It is not the first time, that games have been tried in the educational field. I remember seeing a game called Atlantis, where the object is to learn to manage the many aspects of a country.
Some multi-player games are very good for teaching cooperation.


In the Immune Attack we take the role of a nanobot, which we must navigate through a 3D environment of blood vessels and connective tissue, to retrain non-functional immune cells. Along the way, we learn about white blood cells and infections, and immunology in general.

FAS stated the objectives of the games as:

Upon completion of Immune Attack, the student will be able to demonstrate understanding of:

  • The role of macrophages and neutrophils in the immune system
  • The process of transmigration of monocytes
  • How the body uses chemical signals to find the site of infection
  • How the body uses chemical markers to recognize enemies
  • How macrophages “call” neutrophils for “backup”

I think this is a very exciting way to learn immunology. I expect there will be more games of this kind in the future.

The game can be downloaded for free, it is over 500M, and runs under Windows XP. If you don't want to download it, you can still have some idea of the game by watching videos of the game on the FAS site.

Einstein's position on religion revealed in a letter

The Guardian reported that a little known letter of Einstein will be auctioned, and expected to fetch the price of £8,000.

The letter helps to clarify the misunderstandings in interpreting what he meant when he said "Science without religion is lame, religion without science is blind."

In the letter, he states: "The word god is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honourable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can (for me) change this."

He clearly rejected conventional religion, although he is said to have a "cosmic religious feeling" which had permeated throughout his scientific works.
Being religious is very different from believing in a personal God: "I cannot imagine a God who rewards and punishes the objects of his creation, whose purposes are modeled after our own -- a God, in short, who is but a reflection of human frailty."

Lorenz, "Father of Chaos Theory" died at 90

Edward Lorenz, Professor at MIT died, he was 90. Lorenz, a meteorologist, was known for many of his contributions in Chaos theory, hence nicknamed "the father of Chaos theory".

Among some of his famous findings which have now become popular were:

1. Discovery of deterministic chaos: " His discovery of "deterministic chaos" brought about "one of the most dramatic changes in mankind's view of nature since Sir Isaac Newton," said the committee that awarded Lorenz the 1991 Kyoto Prize for basic sciences. It was one of many scientific awards that Lorenz won." (physorg.com)

2. Lorenz attractor is a relatively simple attractor with complex behavior. This becomes the typical characteristic of chaos, complexity out of simplicity. (see image from "The Lorenz Attractor in 3D", the site has many other images of the Lorenz attractor)


3. Butterfly effect, the scientific concept that small effects lead to big changes, is illustrated by of the Lorenz attractor, see a Java animation here. The butterfly was originally a seagull, here is the story:

In a paper in 1963 given to the New York Academy of Sciences he remarks:

One meteorologist remarked that if the theory were correct, one flap of a seagull's wings would be enough to alter the course of the weather forever.

By the time of his talk at the December 1972 meeting of the American Association for the Advancement of Science in Washington, D.C. the sea gull had evolved into the more poetic butterfly - the title of his talk was* Predictability: Does the Flap of a Butterfly’s Wings in Brazil set off a Tornado in Texas?
4. Every day things are chaotic, chaos leads to creativity and life. The "edge of chaos" is where creativity "happens".

Lorenz's discovery shocked the scientific world. Chaotic systems soon began to be recognised in all branches of science. As mathematicians started to unravel its mysteries, science reeled before the implications of an uncertain world intricately bound up with chance. The human heartbeat is chaotic, the stock market, the solar system and of course the weather. In fact the more we learn about chaos the more closely it seems to be bound up with nature. Fractal structures seem to be everywhere we look: in ferns, cauliflowers, the coral reef, kidneys… Rather than turn its back on chaos, nature appears to use it and science is beginning to do the same.

Recently mathematicians have shown that you can control chaos. For instance here in the Mathematics and Physics Departments at The University of Queensland theoretical and experimental work with lasers shows that the rich structure inherent in chaos can be harnessed to expand the capabilities of lasers. Perhaps in the future single systems, which are capable of multi-tasking, such as the brain, will be modelled by chaotic systems. We still have a lot to learn about how nature uses chaos, but perhaps unpredictable behaviour is not undesirable.

As Henry Adams said "Chaos often breeds life, when order breeds habit" (maths.uq.edu.au)

New Findings on Loving Kindness Meditation

Benefits of meditation have often been reported, see e.g. Meditation increases grey matter in right hemisphere of the brain.

Benefits range from concentration, stress reduction, to increases in the brain's grey matter.

These results have been associated mostly with Vipassana or mindfulness meditation.

For Metta Bhavana (Loving Kindness Meditation) no such study has been made until recently, a group of neuro-scientists wrote a paper " Regulation of the Neural Circuitry of Emotion by Compassion Meditation: Effects of Meditative Expertise"

They used functional magnetic resonance imaging (fMRI) techniques to show increase activity in insula due to meditation training.

The result was also reported in the Scientific American article "Meditate on This: You Can Learn to Be More Compassionate"

It indicates that it might be possible for compassion and loving-kindness to be learned. Buddhists have always believe that we can develop our mental faculties, including compassion, like we build our muscles.

Metta Bhavana is one of the cornerstones of Buddhist meditation, in the Theravada and the Mahayana traditions. It complements Samatha and Vipassana meditation. Samatha aims at tranquility and leads to Jhanas, Vipassana leads to Insight and Purification. Metta Bhavana tenderizes the heart and develops good-will, it can be practiced separately or together with the other types of meditation. Many schools teach all three types of meditation.

Some Guided Metta meditation tapes:

Germany Declares 2008 Year of Mathematics: You Know More Math Than You Think

The year 2008 has been declared the year of Mathematics in Germany, with the motto "Everything that counts".

It followed, from 2000 to 2007: the year of Physics, year of Life Sciences, Geo Sciences, Chemistry, Engineering, Einstein year, Informatics year, and the Humanities year.

As a mathematician, I find the planned activities of the year of Mathematics very laudable. It seems that their main theme is "you know more Math than you think". They avoided abstract Math and the remoteness of Mathematics in ivory towers, and instead stresses how near Mathematics is in our everyday life. We use and know Mathematics, sometimes unconsciously, more than we realize.

When we hear mp3, we do not realize that Math is involved in the compression algorithm. We use cell phones all the time, but we do not think of the Mathematical problems of the allocation of frequencies. Each time we deliberate in making our decisions, we employ probabilities and optimization. The world of finance is now unthinkable without Math. Parking cars involve some geometry of curves. In the medical world, Math plays a great role in the calculations used in the computer tomography imaging. Game theory and Mathematics of Voting are some of the newer branches of Mathematics with many applications in everyday life.
And so it goes on. See more of it here, What moves Mathematics, and Mathematics in life.

Popularizing Mathematics is sometimes done by showing the fun side of Math, puzzles, tricks, curiosities, and entertainment. I am glad that in the year of Mathematics program, the fun side is there, but emphasizing applications is more important than just frivolities.

Darwin Day Celebration

The Darwin Day Celebration is an international effort that is now an official program of the Institute for Humanist Studies. On or near Feb. 12, people around the world celebrate science and humanity on the anniversary of Charles Darwin's birth.

For Release

This Feb. 12 is the 199th anniversary of Charles Darwin's birth.

Hundreds of groups across the United States and the globe will celebrate the date as "Darwin Day" in honor of the discoveries and life of the man who famously described biological evolution via natural selection.

"Darwin Day promotes understanding of evolution and the scientific method," said Matt Cherry, executive director of the Institute for Humanist Studies which runs The Darwin Day Celebration. "This celebration expresses gratitude for the enormous benefit that scientific knowledge has contributed to the advancement of humanity."

Next year will mark both the 200th anniversary of Darwin's birth and the 150th anniversary of the 1859 publication of Darwin's "The Origin of Species", which presented the scientific theory that populations evolve over generations through natural selection.

The theory of evolution was controversial in Darwin's time and remains controversial in the United States today.

Recent Gallup polls show that 43 percent of Americans reject the theory of evolution and instead believe that "God created human beings pretty much in their present form at one time within the last 10,000 years or so." And at least four 2008 presidential candidates have said they do not believe the theory of evolution.

The Darwin Day Celebration started with one event in 1995. Last year there were more than 850 Darwin Day events world-wide. Darwin Day festivities can include debates, lectures, essay contests, film festivals, museum exhibits, art shows and even an "Evolution Banquet" with "Primordial Soup" followed by a "Darwin Fish Fry."

For information, visit: www.DarwinDay.org

Course available (free):
SCH100: Evolution, Creationism and the Nature of Science (Cornerstone) Massimo Pigliucci, Ph.D.: Evolution, Creationism and the Nature of Science will use the contemporary example of the evolution-creation controversy to provoke critical thinking about the nature and function of science as a method for understanding the world we all share. Intelligent Design and other forms of creationism will be explained and rebutted, highlighting the characteristics of empirical vs. anti-scientific and pseudoscientific thinking.

Darwin quotes:
-----------------------------------------------------------------------------------------------------------------------------------

I cannot persuade myself that a beneficent and omnipotent God would have designedly created parasitic wasps with the express intention of their feeding within the living bodies of Caterpillars—Charles Darwin

-----------------------------------------------------------------------------------------------------------------------------------

I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection— Charles Darwin

Believers in human evolution, statistics

A 2005 survey of people in the US and European countries found that people in Iceland, Denmark, Sweden, France, Japan and England have the largest number of believers of human evolution from animals.
By contrast, Turkey and the US have the smallest number of believers.

See the chart here.

The report titled Public Acceptance of Evolution was written by Jon D. Miller, Eugenie C. Scott, and Shinji Okamoto.

They attributed the low acceptance of evolution in the US to widespread fundamentalism and the politicization of science in the United States.

Apparently many Americans have not read articles such as the 2002 Scientific American's 15 Answers to Creationist Nonsense and the more recent National Academy of Sciences' booklet: Science, Evolution, and Creationism.

It would be interesting the see similar statistics for other countries such as Russia, India, China, and the Middle East.

Evolution Is Science, Creationism Is Not

The American National Academy of Sciences (NAS) and the Institute of Medicine has published a booklet to outline their position on Science, Evolution, and Creationism. The booklet is not only for policymakers and teachers, but for the general public. It "better explains evolution in ways the public can readily understand," said NAS President Ralph Cicerone.

In summary, the booklet says that the evidence for evolution is overwhelming. The data comes from various fields including fossils records, DNA research, and common ancestries.
Evolution is as scientific as the theory of gravitation.

Creationism is a belief, and therefore does not belong in science classroom. Creationism is not science, it is based on the beliefs about an entity outside the natural world.

Interestingly, Physicist Lawrence Krauss of Case Western Reserve University in Cleveland, Ohio, made a connection to the US presidential candidates: "When candidates for president can raise their hands to say that they do not believe in evolution, it is clear that we need to do a far better job of educating people," he says. "This is precisely what the new NAS publication attempts to do."

IBM to count carbon emissions for cash

IBM is probably one of the first of the large IT companies to have a share of the growing carbon business market.
Volume of carbon trading reached 10 billion USD in 2005.
A report by news.com talks about GreenCert, an application software to accurately measure corporate efforts to reduce greenhouse gas emissions.

"Many companies are undergoing initiatives to reduce their carbon emissions, as part of corporate social responsibility or environmental programs.

Having a method to measure and certify those reductions is significant because it will allow those companies to sell those carbon offsets, according to IBM. The application is part of IBM's Big Green Innovations initiative to develop clean technologies.

"The whole point of the application's output is to give you a high-quality offset that is transparent and reproducible," said Tim Kounadis, director of worldwide channel marketing for the company."

20-year UnderGraduate Proved Simplest Universal Turing Machine


Stephen Wolfram is the author of the book "A New Kind Of Science", and the founder of the software "Mathematica". He postulated in his book, that the 2,3 Turing Machine is universal.
This has now been proved by 20-year Alex Smith, an undergraduate from Birmingham university. He thereby won a prize of $ 25,000 set by Wolfram.

The idea of a universal machine originated from Alan Turing in 1936. He defined a machine now called Turing machine, capable of computing anything that is computable at all. The machine is only conceptual, not a hardware. It has an infinite 1-dimensional tape, and a read-write head which can also move left or right.

Digital computers are also universal in a sense that it can be programmed to compute any computable function. The difference with a Turing machine is that a Turing machine has infinite storage (tape), whereas digital computers are finite, so digital computers are not really universal.

People have asked what is the simplest possible Turing machine. A 7,4 machine is found to be universal. The numbers 7,4 refer to the number of states of the head (7) and the colors of the tape (4).
Wolfram later discovered a smaller 2,5 machine, and postulated that a 2,3 machine is universal, which according a 40-page proof by Alex Smith, indeed is.

This machine has only 2 states and 3 colors, and it is amazing that such a simple machine can compute (in theory) complex differential equations, make weather predictions and financial calculations. In theory of course, since the Turing machine is not known to be (time) efficient. Still it is more powerful than computers with highly dense electronics.

So, what is the practical application of the new discovery? Wolfram said "Perhaps one day there'll even be practical molecular computers built from this very 2,3 Turing machine.
With tapes a bit like RNA strands, and heads moving up and down like ribosomes.
When we think of nanoscale computers, we usually imagine carefully engineering them to mimic the architecture of the computers we know today."

Wolfram thinks the philosophical implications are also important, "that above a very low threshold, all systems will be exactly equivalent in their computational capabilities."

Einstein and "The Old Man"

Because Einstein was a highly respected figure, what he said about God and religion, are often quoted to support various views from atheism to all shades of religions or beliefs.

What is actually his relation to God, or "The Old Man", a term he sometimes used to refer to God?

A way of speaking.
To begin, it seems stupid to point out that when he says "The Old Man does not play dice", he does not in any way imply that God exists, any more than implying that God is male. It is just a way of speaking common with many. This much is obvious, yet there are people who uses such quotes in discussions to imply that Einstein believed in God, instead of reading it as meaning that the universe is deterministic, not random.
I used the word "I" quite often, although I believe in non-self, because it is convention in communication.

Being religious.
One of his often quoted statements is "Science without religion is lame. Religion without science is blind."
As a scientist, he expressed the importance of religion and beliefs in general.
But religion does not necessarily mean God, and God does not necessarily mean a personal God who has a child, gets angry, and generally interferes in human affairs.

Being religious for him means "To sense that behind anything that can be experienced there is something that our minds cannot grasp, whose beauty and sublimity reaches us only indirectly, this is religiousness."
And "Try and penetrate with our limited means the secrets of nature, and you will find that, behind all the discernible laws and connections, there remains something subtle, intangible, and inexplicable. Veneration for this force beyond anything we can comprehend is my religion. To that extent I am, in fact, religious."

In other words, being religious is some form of incompleteness (Dukkha) of science.
Religion is like a hypothesis to be verified - then it becomes science - or refuted and discarded, while humbly accepting that there are always things we don't understand.
It is not dogma. It is not absolute.
Einstein also rejected religious rituals, just as J. Krishnamurti did.

Rejects Personal God.
His rejection in a personal God began already when he was in school, and he repeated this rejection many times later.

"I cannot imagine a God who rewards and punishes the objects of his creation, whose purposes are modeled after our own -- a God, in short, who is but a reflection of human frailty."

"The idea of a personal God is an anthropological concept which I am unable to take seriously."

"I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it."

"I have repeatedly said that in my opinion the idea of a personal God is a childlike one, but I do not share the crusading spirit of the professional atheist whose fervor is mostly due to a painful act of liberation from the fetters of religious indoctrination received in youth. I prefer an attitude of humility corresponding to the weakness of our intellectual understanding of nature and of our own being."
In this last quote, he preferred the agnostic attitude, and rejected atheism.

What kind of God?
If not a personal God, then in what kind of God did he believe in?
"I believe in Spinoza's God who reveals himself in the orderly harmony of what exists, not in a God who concerns himself with the fates and actions of human beings."

The closeness of Spinoza's God and Buddhism, both believing in a cosmic religious feeling, led him to say:

“The religion of the future should transcend a personal God and avoid dogma and theology. Covering both natural and spiritual, it should be based on a religious sense arising from the experience of all things natural and spiritual as a meaningful unity. Buddhism answers this description…If ever there is any religion that would cope with modern scientific needs it would be Buddhism.”

Science and religion.
The distinction between "what is" and "what should be" describes the all important difference between science and religion. The boundary of "what is" and "what should be" is not strict, there is interaction between the two:

"Yet it is equally clear that knowledge of what is does not open the door directly to what should be. One can have the clearest and most complete knowledge of what is, and yet not be able to deduct from that what should be the goal of our human aspirations. Objective knowledge provides us with powerful instruments for the achievements of certain ends, but the ultimate goal itself and the longing to reach it must come from another source. And it is hardly necessary to argue for the view that our existence and our activity acquire meaning only by the setting up of such a goal and of corresponding values. The knowledge of truth as such is wonderful, but it is so little capable of acting as a guide that it cannot prove even the justification and the value of the aspiration toward that very knowledge of truth. Here we face, therefore, the limits of the purely rational conception of our existence.
But it must not be assumed that intelligent thinking can play no part in the formation of the goal and of ethical judgments. When someone realizes that for the achievement of an end certain means would be useful, the means itself becomes thereby an end. Intelligence makes clear to us the interrelation of means and ends. But mere thinking cannot give us a sense of the ultimate and fundamental ends. To make clear these fundamental ends and valuations, and to set them fast in the emotional life of the individual, seems to me precisely the most important function which religion has to perform in the social life of man. And if one asks whence derives the authority of such fundamental ends, since they cannot be stated and justified merely by reason, one can only answer: they exist in a healthy society as powerful traditions, which act upon the conduct and aspirations and judgments of the individuals; they are there, that is, as something living, without its being necessary to find justification for their existence. They come into being not through demonstration but through revelation, through the medium of powerful personalities. One must not attempt to justify them, but rather to sense their nature simply and clearly. (The World as I See It)"

This is how conflict often arises: "For science can only ascertain what is, but not what should be, and outside of its domain value judgments of all kinds remain necessary. Religion, on the other hand, deals only with evaluations of human thought and action: it cannot justifiably speak of facts and relationships between facts. According to this interpretation the well-known conflicts between religion and science in the past must all be ascribed to a misapprehension of the situation which has been described."

The world would be more peaceful if we all adhere by the limitations of both science and religion.

Osama Bin Laden speaks against Artificial Intelligence

What has Osama Bin Laden got to do with artificial intelligence? In his latest taped speech (transcript by ABC news ), he refers to Noam Chomsky (Wikipedia background on Noam Chomsky) as "among the most capable" of commentators on the Iraq war.

The connection to artificial intelligence is revealed in an exclusive by Mind Hacks, which claims to be a deleted part of the Bin Laden speech.


The deleted part says:

People of America: while the cognitive revolution started within your own shores and changed the face of the world, it seems the lessons of the destruction of behaviourism have not been learnt.

Through the careful analysis of Chomsky, it was clear that language could not be entirely accounted for by the influence of environment and culture on a general learning mechanism. While some heeded the messages, some of your brethren remained unconvinced.

Now that the spectre of connectionism has raised its ugly head and has been inappropriately glorified by the power of technological corporations, our understanding of the role of transformational grammars in language development is threatened.

And I tell you, artificial intelligence is a false god that provides correlative and not causal models of language acquisition. The infallible methodologies are the comparative study of world languages and lesion analyses of those who must be treated with mercy owing to their acquired dysphasias [Microsoft Bookshelf: difficulty in expressing or understanding thought in spoken or written words, caused by brain damage].


So Bin Laden is against behaviourism, connectionism, and artificial intelligence.

100,000 Online Books In A Messy Classification System

The list of books on the website 2020ok.com is very impressive. 30,000 books on computers, 35,000 on fiction, 17,000 on science, and so on.

Here you can find modern as well as classical books like "A Fool And His Money" by George Barr McCutcheon, "Applied Quantitative Finance" by W. Härdle, "The religions of China : Confucianism and Taoism described and compared with Christianity" by Legge, Werke (Volume 5) by Gauss (the great Gauss), "A course of pure mathematics" by Hardy, Bernhard Riemann's "Gesammelte Mathematische Werke", "Elliptische Functionen und Algebraische Zahlen" by Weber, "Geometrie der Zahlen" by Minkowski.

The trouble is, the classification is very badly messed up. You find for example Gauss' Werke classified under Business, BioLogic under Manga, Travel under Biographies and Memoirs, Unpublished Upanishads by C. Kumham Raja under Travel, and many more. The classification system is strange, System Theory is listed under Physics, and it includes entries like "The mathematical theory of electricity and magnetism (Volume 1)" by Burbury.

It would take a lot of work to sort things out, which is a pity, because it has really some great books in it.

The Hyperplanes of Science and Religion

There are 2 views on the relationship between science and religion.

The simplest (View 1) says that there is no relationship at all between the two. We can imagine science and religion here as occupying disjoint multi-dimensional planes of discourse or hyperplanes in space.
This is an easy way out for any possible conflict between the two. Even when they do literally conflict, as in the case about the time the universe was created, there is no logical contradiction if the unit of time is only meant figuratively.
View 1 is an a way unsatisfactory, having both of the bad sides of Einstein's "Science without religion is lame, religion without science is blind." If the hyperplanes are disjoint, neither can say anything about the other.

View number 2, on the other hand, views science and religion in the same hyperplane of discourse. They can occupy different areas of the hyperplane, and not come to contradiction with each other. Imagine a normal plane where science occupies an area on the left and religion on the right. An example is when religion talks about loving-kindness and compassion, and science talks about mass, velocity and acceleration.
However, the body of scientific knowledge will grow with time, and sooner or later, will come to intersect with religion. Evolution definitely bring many religious beliefs in question. The discovery of mirror neurons gives some insight on how compassion developed.
Altruism is an unexpected outcome of the iterated prisoner's dilemma.
In View 2, science and religion can avoid the lame and blind properties referred to in the Einstein quote above. Scientists can have beliefs, which although unproven, motivates their research. The assumptions used in science are often such beliefs used as hypotheses.

When both science and religion address the same topic, and we agree that they are not speaking in different tongues, they cannot be in logical contradiction. And if they do, one of them must be abandoned.
We can then subdivide View 2 into View 2A, where religion holds the absolute truth, and View 2B, where religion is to be modified if ultimately found unscientific.
View 2A is the position of the fundamentalists. Here religion becomes blind faith followed fanatically by its believers.
In View 2B, we use the phrase "ultimately found unscientific", because the scientific community can be wrong for a long time, before somebody realize develop a better theory. Science here is seen as approximations to truth. It is to be noted, that not all religions can fit into View 2B, in fact many religions will fall apart if some of its tenets are taken away.
This is where Buddhism differs from many other religions: "The view endorsed by the majority of Buddhists, is represented by the Dalai Lama who is willing to jettison Buddhist doctrines if shown to be scientifically false (of course with reasonable care, since scientific truth can change also with time)" (see Brouhaha over Buddha on the Brain) .

Nothing is absolutely sacred in Buddhism, all can be questioned. The truth is to be experienced individually, the Buddha can only point the way.

Scientists Develop Internet Catalog of All Earth's Species

Scientists have announced they have begun assembling an Internet catalog of every living thing on Earth. The organizers say the new website will become the single location where researchers can go to study the nearly 2 million known plant and animal species. This so-called Encyclopedia of Life is expected to be a major help to scientists in developing countries.

One of the intellectual forces behind the project is renowned Harvard biologist Edward O. Wilson, who says only about 10 percent of all living things are currently known.

"Our lives depend upon this largely unknown living world that we now propose to understand more fully," he said. "Humanity exists, in other words, on a little known planet. What knowledge we have is scattered all through very technical literature. It is hard to obtain. It is usually available to and known about by a limited number of experts."

It is accessible at http://www.eol.org.

Ajahn Brahmavamso on Buddhism as Science

Venerable Ajahn Brahmavamso Mahathera was born Peter Betts in London, United Kingdom on August 7, 1951. He studied theoretical physics at Cambridge, but later became disillusioned.

His article "Science and Buddhism" has been widely circulated and received a lot of attention. A more recent article is "Buddhism, the only real science".

Among other things, he liked the non-dogmatic character of Buddhism, questioning everything:

Buddhism is more scientific than modern science. Like science, Buddhism is based on verifiable cause-and-effect relationships. But unlike science, Buddhism challenges with thoroughness every belief.
The famous Kalama Sutta of Buddhism states that one cannot believe fully in "what one is taught, tradition, hearsay, scripture, logic, inference, appearance, agreement with established opinion, the seeming competence of a teacher, or even in one's own teacher".

This last article has not gone unchallenged, for example Hor KC in "Ajahn Brahm on science: Jigsaw pieces at all the wrong places" , himself a Buddhist, is against "Buddhism is more scientific than science."
Instead he preferred "Buddhism is beyond science" as Buddhism is not about trying to be, but rather about not trying to be."

At the end of the article, Hor, with tongue in cheek, suggested that Ajahn Brahm was merely testing us.

There is another thing which bugs me: It is the theme of rebirth which Ajahn Brahm repeatedly say. He said that rebirth has been scientifically proved, citing people who can remember their past lives. Rebirth may or may not be true, but subjective experiences do not stand rigorous scientific scrutiny.

That is why many Buddhists prefer to stand clear of metaphysical and other "difficult" questions, better saying simply "I don't know now, but we may know one day". Of course we can believe one way or the other, but believing is not the same as knowing.

Tale of a sexless tortoise shortlisted for science book prize

Epic tales of the earliest Britons, misguided quests for happiness and the long, long life of a sexless tortoise are among the finalists shortlisted for the Royal Society's prestigious annual science book prize, announced today.

Six books remain in contention for the £10,000 prize, which has previously been claimed by Bill Bryson, Stephen Hawking and the eminent string theorist Brian Greene.

This year, the casualties to fall by the wayside include Matt Ridley's biography of Francis Crick, a history of the universe from Patrick Moore and his rock acquaintance Brian May, and the Sun's Giant Leaps, which depicts groundbreaking scientific achievements as front-page splashes.

The shortlisted authors include Eric Kandel, a Columbia University neuroscientist and Nobel prizewinner, whose memoir, In Search of Memory, charts the scientist's career from childhood in Nazi-occupied Vienna to his wide-ranging investigation of the psyche. The scientist, a world authority on the mechanism of memory, asserts that one day medicine will provide a little red pill to boost the memory of those who are losing it, and a little blue pill for those who strive to forget.
