Scientists tell us that the way things work at quantum level are unlike what we experience in our visible world. In macroscopic world “classical” physics of Newton et al rules the roost.

Fundamental particles of the quantum realm behave in seemingly impossible ways: they can exist in two places at once, or disappear and reappear somewhere else instantly. It is so weird that ‘spooky science’ fits the label under which they operate.

Quantum processes may occur not quite so far from our ordinary world as we once thought. Quite the opposite: they might be at work behind some very familiar processes, from the photosynthesis that powers plants – and ultimately feeds us all – to the familiar sight of birds on their seasonal migrations. Quantum physics might even play a role in our sense of smell.

A well-trained human nose can distinguish between thousands of different smells. But how this information is carried in the shape of the smelly molecule is a puzzle. Many molecules that are almost identical in shape, but jigger with one by swapping around an atom or two shall have very different smells. Vanillin smells of vanilla, but eugenol, which is very similar in shape, smells of cloves. Some molecules that are a mirror image of each other – just like your right and left hand – also have different smells. But equally, some very differently shaped molecules can smell almost exactly the same. Luca Turin, a chemist at the BSRC Alexander Fleming institute in Greece observes that there are inconsistencies.

He argues that the molecule’s shape alone isn’t enough to determine its smell. He says that it’s the quantum properties of the chemical bonds in the molecule that provides the crucial information.

According to Turin’s quantum theory of olfaction, when a smelly molecule enters the nose and binds to a receptor, it allows a process called quantum tunnelling to happen in the receptor.

In quantum tunnelling, an electron can pass through a material to jump from point A to point B in a way that seems to bypass the intervening space. For the same reason in photosynthesis of plants how electrons achieve efficiency in photosynthesis owes to the same tunneling. As with the bird’s quantum compass, the crucial factor is resonance. A particular bond in the smelly molecule, Turin says, can resonate with the right energy to help an electron on one side of the receptor molecule leap to the other side. The electron can only make this leap through the so-called quantum tunnel if the bond is vibrating with just the right energy.

When the electron leaps to the other site on the receptor, it could trigger a chain reaction that ends up sending signals to the brain that the receptor has come into contact with that particular molecule. This, Turin says, is an essential part of what gives a molecule its smell, and the process is fundamentally quantum.

The strongest evidence for the theory is Turin’s discovery that two molecules with extremely different shapes can smell the same if they contain bonds with similar energies.

Turin predicted that boranes – relatively rare compounds that are hard to come by – smelled very like sulphur, or rotten eggs. He’d never smelt a borane before, so the prediction was quite a gamble.

He was right. Turin says, “Borane chemistry is vastly different – in fact there’s zero relation – to sulphur chemistry. So the only thing those two have in common is a vibrational frequency. They are the only two things out there in nature that smell of sulphur.”

While that prediction was a great success for the theory, it’s not ultimate proof.

 

Whether or not nature has evolved to make use of quantum phenomena to help organisms make fuel from light, tell north from south, or distinguish vanilla from clove, the strange properties of the atomic world can still tell us a lot about the finer workings of living cells.

According to Merriam-Webster dictionary a miracle is defined as an extraordinary event manifesting divine intervention in human affairs.

On closer examination many events touted as miracle can be interpreted as natural causes. In ancient Greece a bleeding Juniper tree caused great sensation and was venerated by people as a miracle.

‘The phenomenon of bleeding’ tree – in which a mysterious red liquid pours from chopped-down trunks – is one which has left scientists shocked and tree surgeons baffled,’…BBC Two’s documentary series Nature’s Weirdest Events suggest it may happen more often than you think.

Australian Chris Wharton was among those who revealed their shock at seeing a tree apparently pouring blood after he had cut it down, admitting he had ‘the shock of his life’.

‘I do not understand why this tree has apparently blood pumping out of it,’ he said, ‘It was the strangest thing.’

And presenter Chris Packham added that it was by no means an isolated incident, with reports of ‘bleeding trees’ occurring across the world and everything from disease to ‘the supernatural’ being blamed.

The good news is that there does seem to be an explanation for the weird goings-on – with rising sap in the springtime apparently responsible.

‘The sap is at high pressure until the leaves open and begin to evaporate the water, any injury releases this pressure,’ Packham explained.

‘This apparent ‘bleeding’ can look distressing, but it may be the tree’s way of trying to heal.’

In ancient Greece man had no understanding of the forces of nature that assailed his everyday life. He did not have a conception of a single universe and his own reality was ‘ a confused republic full of warring forces.’ According to Fustel d Coulanges he prayed to them and worshiped them;he made them his gods.’  Since man acquired a scientific temper much of his world around him also became orderly. Think of it as Orpheus with his music quietening the wild beasts. He could play music notes arranged to create harmony. He merely settled their untamed nature in harmony with his own art. Science is like Orpheus. A scientist of the Medieval period could not have dreamt up Spooky Science or quantum computing. Suppose an Alien could show man in the Middle Ages the working of quantum world would he not have considered it a miracle? Miracle in a way is a crossover of two different states of being where power of say Alien (in terms of Technology, mastery over multi-dimensional existence) is no match for man whose mastery is merely three dimentional in a 2D universe.

Early in 2014 Jeremy England proposed a theory, based in thermodynamics, showing that the emergence of life was not accidental, but necessary. “Under certain conditions, matter inexorably acquires the key physical attribute associated with life,”a theory, based in thermodynamics, showing that the emergence of life was not accidental, but necessary.

From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat. Professor England, a 31-year-old assistant professor at the MIT, has derived a mathematical formula that he believes explains this capacity. The formula, based on established physics, indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life.

Giordano Bruno, who was burnt at the stake for heresy in 1600, was perhaps the first to take Copernicanism to its logical extension, speculating that stars were other suns, circled by other worlds, populated by beings like ourselves. His extreme minority view in his own time now looks better than ever, thanks to England.

Matter has to out its abstract aspects underlying in a material form that can give matter its rising in the ladder (of evolution) which is just as well that it correspondingly acquires a coherence in its abstract nature.

Light as a photon having velocity and distance to cover shall create an uncertainty principle. If Creationists and Evolutionists cannot agree on the role of God let us not get drawn into the useless polemics. Doubt is necessary in the realm of Material universe.

How did man bring out underlying abstract of nature of matter to propound a theory of anything? Man we say is capable of abstract thinking. So doubt as well as God is borne out of his imagination. What is it if it does not touch anything nor lead to anywhere? It is useless. If a man because of doubt takes a position of sceptic or a Theist it has only value for his species. Science does not prove anything else.

If you were to use the physical distance in terms of size as a model, the height a fly can in one jump will for man work out as high as the Empire State building. This is only a hypothetical model. The different flavors quarks come up with, do indicate space in such infinitesimal confines: correspondence principle gives space a yardstick on which infinite or the least can be held up.

At the level of quarks is there time or space? We might tag so many flavors make up proton or neutron just as we would lay a sheet in vast expanse of grass to have a picnic and call it as our space. Once picnic is over and sheet is taken out, folded and we drive away the so called space is dissolved. So is time. These are only related to us. Yet its reality as a memory(of a picnic on Sunday for example) is swallowed up in space where in we create our realities of everyday life in space. It is only relevant to the observer like finding parking space for your car.

Time is similarly related to the observer.

If God is to conceived as eternal, infinite and omnipresent He must hold as real to me as in the cosmos. As a Christian I believe essence of God is achieved in space regardless of such an infinitesimal space. ‘The kingdom of God is within you.’ Gluons are stronger nuclear force binding realities of sub-atomic particles ie quarks. What makes us believe in physical reality of our bodies and ideas? Do we not believe in our world or in our bodies? Just the same these come up as ever with otherworldly tags.

Our faith though as small as mustard seed can grow as large as to cover as the will of God covers the entire cosmos. God has inscribed truth in our inward parts.
