The Science Museum: not Just a Tourist Hotspot

Friday, September 19th, 2008

Sir William Bragg, the eminent physicist, once stated, “The important thing in science is not so much to obtain new facts as to discover new ways of thinking about them.” The profundity and truthfulness of this statement seems nowhere more relevant than in the National Science Museum in London – one of the country’s most loved historical institutions. As part of the National Museum of Science and Industry, the Science Museum is more than a tourist attraction for London’s many visitors: it preserves some of the world’s most impressive scientific artefacts, while constantly showcasing new talent and the latest in scientific innovations from across the globe.

The Science Museum first opened in 1857 from the collection of the Royal Society of Arts, as well as surplus items from the Great Exhibition of 1851 to promote the achievements of science and technology. Initially created as part of the South Kensington Museum, the museum went through several incarnations before being officially titled the Science Museum in 1885.

Today, the Science Museum holds over 300,000 exhibits. Its most famous items include Stevenson’s Rocket, an early steam locomotive built by George Stevenson in 1829, James Watson’s model of DNA and Charles Babbage’s Difference engine, a special-purpose mechanical digital calculator. The Museum itself is made up of a series of permanent and temporary galleries, including ‘Space’, a historical gallery that tells the story of human space exploration, ‘Flight’, which contains a number of aeroplanes and helicopters, and ‘Making the Modern World’, a new gallery which houses some of the museums’ most iconic collections.

Since December 2001, the museum has been free to all visitors, and is therefore a popular attraction for families in Britain. In fact, the Science Museum also organises “Science Night” – described as an “all-night extravaganza with a scientific twist”. On these evenings, up to 380 children aged between 8 and 11 are allowed to spend an evening in the museum performing enjoyable, science-based activities before being allowed to spend the night among the exhibits. In the morning, the participating children can awake to breakfast in the museum, more scientific-based fun and an IMAX film – an altogether unforgettable scientific experience!

But the Science Museum doesn’t simply provide a place for children to learn and play amongst some of the world’s most important scientific developments: it also opens up forums for controversial scientific debate. The Dana Centre, a groundbreaking urban bar and café, was opened in 2003 in an annex to the Museum, and is currently the UK’s only dedicated scientific discussion venue for adults.

As an integral part of the National Museum of Science and Industry (which includes York’s National Railway Museum and the National Museum of Photography, Film and Television in Bradford), the Science Museum plays a crucial part in the scientific education of much of Britain’s population.

If you’re hoping to visit the Science Museum, you’re sure to find a range of London hotels located in South Kensington through a variety of online travel sites. So choose to spend a day – or a night – in the Science Museum, not just because it provides fun for children and adults alike but because, as an institution of scientific progress and learning, it’s virtually unparalleled.

Can Intelligent Design Be Science?

Friday, September 19th, 2008

How did our universe come into existence?

The question of how our universe came into existence has mystified scientists, philosophers and lay thinkers for centuries. The fact that we are here, suggests an origin. Yet the universe’s origin, from a scientific perspective, is far from clear-cut or obvious. Even more puzzling is that in this age of high-tech, when we can peer into vast regions of space, penetrating literally billions of light-years into the cosmos, as well as observe phenomena on the microscopic and atomic levels, the origin of our universe is still not that obvious.

Or is it?

Is it possible that the origin of our universe is staring us right in the face and we don’t see it? Like the old murder mystery about the police who question the postman for hours as to who he saw near the house on the day of the murder. But it never occurs to them that the postman might be the murderer.

When confronted with questions about the origin of the universe, scientists usually speak of the “big bang.” In 1929, astronomer Edwin Hubble published his finding that the universe is expanding. That is, in any direction you look up into the sky, you will find that most stars are flying away from us.

Hubble’s discovery led to an extrapolation of where all matter in the universe might have begun. If the direction of all the galaxies flying apart were reversed, it appeared that everything would meet at one point. At some distant past, scientists believe, all matter in our universe began at that one single point, exploded, and, thus, the “big bang.”

Scientists also believe that the laws of nature at the moment of the big bang must have had some remarkable properties. All matter in the universe being condensed into such a small area would have produced something called a “singularity” — a point of infinite density in which, much like the inside of a black hole, time and the laws of nature, as we know them, cease to function. And it is this singularity that prevents the formulation of theories about the universe prior to the big bang — if the big bang totally distorted the laws of nature, there’s no telling what “nature” might have been like prior to that.

Some view the big bang as science’s answer to our origin, other’s view the complexity of our universe as proof of a Creator. These two camps have held their ground for many years now, and a “Time Magazine” article entitled “Science, God and Man” pretty much reflected these ongoing contentions.

At one point, the Time article seems to maintain that our ability to decipher some of science’s mysteries and complexities seem “enough to dampen a person’s hopes for higher meaning.” The very next paragraph makes the paradoxical statement that “looking at the big picture … there is more to this universe than meets the eye, something authentically divine about how it all fits together.”

A deeper analysis of this subject matter, however, might demonstrate how some of the above contentions are simply wrong. The big bang answers very little. Describing the complexities of our universe is not at all necessary to ponder the existence of a Creator, and solving some of science’s mysteries does not in any way detract from the need for a Creator.

To begin with, the entire big bang scenario only adds a step to the question of “Where did we come from?” The big bang refers to only one point in time. The originating force that gave the big bang its power and potency would be the key to “where we came from.” Of course, you could add several more steps, as scientists sometimes opt to do, almost in seriousness, that there may have been other universes before or parallel to ours. But this only adds unverifiable assumptions, clouds the issue and solves nothing.

To talk about a “beginning” you have to go back to a time before which literally nothing existed. And this is what science does not and cannot do.

The universe we live in gives every indication of having “come from somewhere.” The laws of nature dictate this. Nothing in our universe seems to have the ability to create or destroy itself. Matter and energy only go through transformations, with no elementary (subatomic) particle components gained or lost, in the big scheme of things. A fire may destroy a house, but every subatomic component that encompassed the house is still in existence after the fire. An atomic bomb may destroy an entire city, but only in the form of a transformation, no substance is actually lost to some exotic void.

In the same vein, nothing in our universe is ever created. Stars are formed (of gas), they do not “create” their constituent components. Meteorites are formed (or chipped off larger bodies), they do not “create” rock or ice. Apple strudels are baked, they do not come from strudel machines.

This leaves us with a very serious dilemma. Based on known laws of nature — that nothing can create itself — our universe shouldn’t exist. But it does.

At one point, scientists thought they had the answer when they observed subatomic particles appearing from “nowhere.” It seemed only logical that if enough subatomic particles created themselves they would eventually form an entire universe.

This notion, however, of “something” coming from “nothing” is neither logical not scientific. The entire concept of “nothing” implies complete and utter nothingness — nothingness not only in substance, but also in potentiality. Something that has the potential to produce anything, even if at present it has no observable form or properties, is obviously not “nothing” — it is apparently a latent force of some kind.

Furthermore, to verify that “something” came from “nothing,” you’d have to prove that there was in fact nothing there to begin with. And that’s impossible. For “detecting nothing” can always mean that your experiment or apparatus is simply not sophisticated enough. In fact, the very fact that something seems to suddenly appear from “nowhere” is, ironically, concrete proof that something actually does exist where you think there is nothing.

And this is precisely what scientists discovered in the above case. As science became more sophisticated, it became apparent that what scientists previously thought came from “nothing” was actually a transformation of a more basic or subtle form of subatomic substance into a form more readily detectable with cruder observational methods.

So, the question of “Where did our universe come from?” isn’t just some idealistic venture into the realm of metaphysics. It isn’t just some exercise in nonsensical philosophical deliberation. It isn’t a “complex” scientific question which we may have the answer to in the future. It is, scientifically speaking, a profoundly disturbing question which the laws of nature themselves indicate is unanswerable. No matter how long you claim the universe has been in existence, no matter how powerful that big bang may have been, no matter what kind of transitions the laws of nature may have gone through during that big bang, at some point in the past all the stuff of the universe (or universes) had to come into existence. How?

The only possible explanation is that the ultimate origin of everything that exists must have been from a source that is itself not bound by our laws of nature. A source which did not necessarily have to “come from” anywhere. This may not be an easy concept to comprehend. But the alternative leaves us with the completely irrational, unscientific and absurd notion that in spite of the fact that our universe exists, there was no way for it to have come into existence.

At this point, to start entertaining the thought of a Creator isn’t simply a “convenience,” a “way out,” a “fanatical” view, or even “religious dogma.” It is a very realistic, necessary and logical step in explaining our existence. Furthermore, it can even be classified as science. The concept of a Creator is no more removed from science than the notions of “other universes,” the inner workings of black holes, the laws of nature at the moment of the big bang, and a host of subatomic particles that scientists spend literally millions of dollars trying to track down that never pan out. These scientifically unverifiable concepts, based solely on logical deductions, are quite clearly entertained by bona fide scientists. Then why not the “theory” of a Creator? What can be more logical than the notion that a universe with laws of nature that preclude its own creation to have been brought into existence by a Creator? And what alternative would be more logical or scientific?

Apparently, the inclination to avoid a Creator at all cost by some, constitutes nothing but an extreme form of bias. It has nothing to do with logic or science.

Getting back to the Time article: That scientific advances are somehow “enough to dampen a person’s hopes for higher meaning” is totally absurd. The need for “higher meaning” (a Creator) does not stem from the complexities of our universe. It stems from the simple fact that the universe exists. What’s more, if the entire universe contained nothing but one spec of dust, it would suggest a Creator, since the spec of dust could not have created itself. If the universe contained an imponderable amount of mass and energy, as it does, but none of it in any complex or aesthetic form, it would most certainly suggest a Creator. So by the time you get around to talking about complexities, you’ve already gone way past the point of establishing the fundamental need for a Creator. The complexities, at that point, far from “dampening hopes for higher meaning,” go a long way in describing the power, resourcefulness and ingenuity of the already-inferred Creator. And the more complexities you decipher, the more brilliant a Creator you establish.

Personally, I think one of the most brilliant aspects of Creation is, ironically, those people who don’t believe in God. To Create an intelligent person, put him in the midst of a universe that seems almost limitless in space, energy and matter, give him the scientific capability of deciphering some of the universe’s complexities and secrets, and, at the same time, endow him with an emotional feature that somehow gives him the capacity to deny that any of this required a Creator, is about as brilliant as the implementation of “free will” can get.

Science Nowadays

Friday, September 19th, 2008

If we are going to look closer to the elements of both, science and religion, we can observe that science is more connected to physical points and religion is more connected to insubstantial points. So, the essence of science can not be compared with the essence of religion as they are the opposite sides of one whole. In other words we can say that science answer on the question ‘How?’ and religion answers on the question ‘Why?’

But nowadays science tries to be general and not only to give the answers on ‘how’, but to be able to explain why and for what. Science also wants to comprehend the world as the religion did it. People want to see more then they see now and not always science can explain this. And only due to this fact science can not be as important as religion. Humans are so eager to know more and if science has no opportunities to propose the answers, humans turn to religion and satisfy their desire.

But nevertheless, the scientists do want to give for their work high rank and the same time right. But how much the desire was it can not be proved as there are not enough facts to make it real. So, the theory without necessary facts can not be correct and the facts for science can not be always demonstrated, but sometimes it can be proved to be false as a result for great number of researches.

There are a lot of persons who criticize the science. For example, Karl Popper proposed the theory according to which the facts to the scientific researches are only prospects and it need a lot of time in order to drop or to adjust the theory. Thomas Kuhn said that a lot of scientist just fit their experience to the already existed ones.

Science Vs Religion

Friday, September 19th, 2008

In the frames of this article we are going to condemn science and the persons who work on this field, and the wrong statements made by the scientists. Then, we are going to point out the resemblance of art and science and their differences. It goes without saying that criticism is obvious for any science and, specially, for art. But not any critics can be accepted, it is very important to prove the facts and be ready to explain all the points. So, in the article we try to propose the elements of critics and the facts.

First of all, science mistakably regarded as religion and with time got the same status and the same rights to influence on people. On the day of its birth science supposed to develop and become a theory and, by the way, to get the necessary qualities in order to replace the religion and to be ready to give the answers on the questions on which religion could not answered. Using different methods and techniques in XXI century science had enough powers to stand on the place of religion, it turned to be the issue for faith and even for devotion. Such situation developed very quickly and the trust in science turned into unquestionable correctness.

Emile Durkheim was first who stated the science as the theory. Such theory had the opportunity to provide with enough time and proposed official religion but the base for it was science. The presence of great number of science permit the belief in the facts which were proposed by them and it was the reason for quick replacing of the religion on the second place even in the questions concerning the creation of the world. But such unquestionably facts were of double nature. First of all, science is grounded on the experience and it is certainly impossible to make any experiences on the creation of the world and the correct facts are still unknown. Secondly, science and religion are very different in structure and size, so it is wrong to stand these two things as science and religion into one row.

Feng Shui Lighting – The Facts

Friday, September 19th, 2008

To a certain extent because of the way that it is represented in the media, feng shui is often represented as a somewhat mystical or mysterious idea that is difficult to study or to prove. However, scientific research shows that some aspects of feng shui have a measrably positive effect on attitude and mood. Traditional feng shui practices attempt to create a harmonious environment that allows its occupants to remain happy and relaxed, and studies show that at least some feng shui techniques are definitely more science-fact than science fiction.

Some of the most effective feng shui rules with a scientific basis for their success have concern lighting, and there is every indication that using feng shui techniques as a method of lighting your home will prove to be a wise decision. If the illue alludes to whether lighting your home according to feng shui principles will improve your quality of life, the answer is an incontrovertible yes. According to the scientific body of knowledge we have accumulated on the subject of lighting and emotion, feng shui offers a reasonable and viable method for improving one’s mood by creating a calming atmosphere by means of light.

Feng shui aims to assist you in creating a balanced, harmonious atmosphere, and an important part of achieving that goal is finding lighting solutions that provide visibility without being garish or unpleasantly bright. Because of this, feng shui exponents often recommend including multiple sources of soft light rather than a single source of strong, bright light. Science supports this, showing us that having multiple light sources in a room allows the eye to see depth and contour more easily, which means optimum visibility. The lighting arrangements that feng shui suggest mimic the naturally multi-sourced light found in the outdoors, which is the kind of lighting situation that humans have evolved to see best in.

When we can see everything in our space, we are more likely to be calm and relaxed for a very simple reason that has its roots in out evolution. Although few people in the modern world are consciously afraid of being attacked by a lion or other fierce marauder, our brains are hard-wired to protect us by searching for predators. When there are no blind spots or dark areas nearby, we can be certain that there are no dangerous predators hidden in the vicinity. When you light a room according to the principles, you have the optimum lighting situation to lead to ease and therefore relaxation.

Traditional feng shui dictates that it is important to use a series of soft lights in different areas of the room in order to allow the unhampered flow of positive energy throughout the space. There is no way for science to evaluate whether this goal is achieved or not, but research can tell us that the lighting situation feng shui creates allows for maximum visibility, which in turn promotes relaxation, calm and happiness.

From Science-fiction to Science Fact: Seeing is Believing in the Age of the Internet

Friday, September 19th, 2008

For most people, sci-fi is pure fantasy and a means to provide some escapism from the hum-drum of everyday life. Programmes such as Star Trek and Doctor Who have drawn legions of dedicated fans, studying each scene, memorising lines and analysing sub-plots for hidden meaning. Indeed, the impact that the sci-fi genre has had on popular culture is probably incalculable.

Many modern-day inventors and scientists admit to being inspired by shows such as Star Trek. The communicator-like ‘flip-phone’, for example, is now commonplace. And in medicine, laser ‘scalpels’ have even been developed. In some respects, we may even be centuries ahead of the world that is on display in Star Trek, given it was set in the 23rd century.

Indeed, the world we see today is different altogether from the one 100 years ago. At the beginning of the 20th century, some people said that everything that could be invented had been: the telephone, the automobile, recorded sound, moving images and the first flight had taken place. But, of course, the surface of the technology revolution hadn’t even been scratched. The 20th century saw man travel faster than the speed of sound and go to the moon; and televisions in every household. And the 20th century also saw the invention of perhaps the biggest influence on how we live our lives since the humble telephone; the personal computer.

But at first, the PC was initially a plaything for computer geeks and games enthusiasts. To bring computers to the masses, something else was needed. Something that would revolutionise the way people lived their everyday lives. And that, of course, was the internet.

Besides allowing people to shop online or verify just about any fact there is to be verified, the internet has added a new dimension altogether to the world of communication, and has brought advances way beyond the capabilities of the humble telephone.

Whilst ‘chatting’ online has been fairly commonplace for a number of years, either through instant messaging services or internet-telephony technology, all that was really new about this was the medium. Now though, video calls can be made across the internet to anywhere in the world, bringing to life the visions of those who created the likes of Star Trek more than 40 years ago.

And what is truly revolutionary about being able to communicate face-to-face over the internet, is not only the fun and enjoyment it creates, but also it’s free. All that’s needed is a computer, an internet connection and a mic-enabled web-cam, and it’s good to go.

So, with internet technology and a little inspiration from the world of sci-fi, it’s now possible to say hello, and wave goodbye. And whilst we may not be able to beam ourselves to the other side of the world quite yet, we’re certainly a few light-years further on from where we were 100 years ago. Seeing really is believing!
