BIG BANG TO BIOLOGY

Ashley Davidoff MD

In the beginning of time there was 0?

In the beginning there was a void, nothing, there was zero

And Then There was 1?

And then 0 and 1 started linking organizing

?. sometimes in the presence of a facilitator and the two equations (1+1=2, and 1+1= 1 were born)

The poem was written following a discussion between 3 school friends inspired by the concept of the whole being greater than the sum of its parts.

1+1 = 1

Davidoff Abelson and Leveen

In the Beginning

There was 0

Then there was 1

Then 0+1 = 1

1 to the power 0 = 1

1 to the power 1 = 1

1 to any power = 1

Any number to the power 0 = 1

Though 0 to the power 0 is indeterminate

And finally 1 + 1 = 1

Big Bang and the Formation of the Hydrogen Atom ? and the beginning of the build up

In the beginning ? about 13.7 billion years ago after a big bang, the universe was so hot and then as it began to cool protons neutrons and electrons were born and then the simplest atom ? the hydrogen atom was born first, and remains the most abundant atom in the universe contributing to 90% of the atoms in the universe. After about 300 million years the hydrogen atoms started to clump together under the force of gravity generating pressure as they clumped and then heat resulting in nuclear fusion. As a result of nuclear fusion of two hydrogen atoms helium , then lithium was formed and then the rest of the elements up to iron (26 hydrogen atoms) were formed (http://www.physicscentral.com/explore/poster-stardust.cfm) Therefore matter formed creating the stars and then galaxies in the heavens and the table of elements on the earth up to iron. After iron nuclear fusion requires more energy than it produces. The inner core of the earth has a large amount of iron.

Big Bang

In the beginning ? about 13.7 billion years ago there was a big bang and the universe was formed. It was very hot but when it started to cool, electrons, protons, and neutrons were born.

The Birth of the Forces of the Universe and the Beginning of Biology

The Birth of Protons, Electrons, and Neutrons

When the universe started to cool the electrons, protons and neutrons were born.

There were two basic forces in nature ? positive and negative, and a neutral force, called the neutron.

In the atomic world, the positive is encapsulated in the proton and the negative in the electron while the neutron resides with the proton in the nucleus.

The Primal Electromagnetic Forces

Positive and Negative

The primal opposites, attracted each other? like nothing else, forming an unavoidable union, while retaining their individuality and going for the most part their separate ways, but remaining bonded. The first and most abundant union and the building block of all to follow is the hydrogen atom consisting of one electron and one proton.

When positive and negative interact ? it is not a simple interaction. It is not a 1+1 =2 , and is closer to 1+1=1. It is like marriage. Firstly by their union they still retain their individuality, go their separate ways with the electron in orbit and the nucleus staying central, but remain bonded and together they form a new unit.

Evolving Units

When a new unit is formed from its component parts, an interaction has taken place in a given space, in a given moment in time, in a given environment. The new unit has unique characteristics that is not manifest in either of the component parts.

At the time of big bang the electron, proton, and neutron were formed.

Formation of the Hydrogen Atom

After the big bang one of the first interactions between the electrons and protons was in the formation of the hydrogen atom An electron (unit 1) interacted with a proton (unit 2) in the heated environment in the space of the universe, at a moment in time, and a new and unique unit 3, called the hydrogen atom was formed. because the interaction resulted in a spinning charge an electromagnetic field was set up and the atom also spun in space in a unique way that was not characteristic of either the proton or the electron.

The hydrogen atom is the building block of all else to come.

The Hydrogen Atom Spinning Precessing Magnetic Field

Mass, Motion, Space, Time and Electromagnetic Force

The spinning hydrogen atom introduces us to the elements of mass, motion, space, time, and electromagnetic forces.

Some Universal Principles

The marriage between the electron and the proton is not a simple one. It is not as black and white as it seems since as a result of the marriage the electron is bound to the nucleus and the proton is bound to the electron. The motion of the electron in an orbit allows it to keep its distance from the proton and prevents the two from crashing and falling head over heels into each other, or nulling each other. The hydrogen atom is set in motion and as a result of the electrical force in motion an electromagnetic field is set up. The spinning of the hydrogen atom forces the atom to be in a certain position in space at a given time as it moves ? Voila ? the elements of space, time and motion, are manifest in the units. The units have mass and elements of electromagnetic and mechanical forces. The interactions, allow bonding, and new units are established. Uniqueness, dependence and independence of each of the units follows. These are elemental and foundational principles common to all matter- organic and inorganic, biological or otherwise and will be repeated ad nauseum in the following texts.

With the birth of the universe, an infinitismal number of hydrogen atoms were born and let loose to build bigger and better units with their new found expression through mass, time, space, electromagnetic force, and motion.

The Birth of the Proton from the Womb of the Hot Hot Hot Universe

Hydrogen, as simplest and lightest atom, remains the most abundant atom in the universe, and contributes to 90% of all the atoms of the universe.

Courtesy Ashley Davidoff MD 102976pb04b10b06b.8s

The electromagnetic forces and the fact that the hydrogen atoms are moving, forced the atoms to come into contact with other hydrogen atoms and random reactions took place in the presence of the given environment in which temperature, mass, motion, space, time, electromagnetic forces, and facilitators were relevant to the reaction and the result was the creation of other atoms and elements.

The Building of New atoms and Elements

Doubling Up the Forces ? Helium

When two hydrogen atoms combined in a given environment, at a moment in time and space, helium the second lightest and second most abundant element in the universe is produced.

And as we double the units of force we find that there is a relatively weak electric force and another force called a strong force

Fission and Fusion ? Strong forces and Electrical forces ? (http://www.youtube.com/watch?v=yTkojROg-t8

And as we build up the negative and positive charges and we add neutrons in the mix the units get linked and organized in different ways to create new units with completely different characteristics

As we add units things start to change to a point where electrical forces start to dominate

The Atom ? The Powerful and Indivisible

This atom has 56 electrons in 6 orbits It is called barium

In this diagram of barium we note the electrons spinning around the nucleus Barium has 56 electrons, 56 protons and 81 neutrons giving it an atomic weight of 56+81 = 137. The electrons atre distributed in the orbits in the following manner 2,8,18,18,8,2.

ttp://en.wikipedia.org/wiki/Electron_shell#Number_of_electrons_in_each_shell

The remarkable similarity between the structure of the atom, and the structure of the solar system, leads one to ponder the recurring organizational pattern of things in between. If one considers the atom as a unit and the solar system as a unit then the technique of combining units to build bigger units more powerful than the individual parts allows us to understand in some measure the unifying units to units concept or 1+1= 1

Atoms are the smallest parts of matter that possess the distinctive chemical characteristics of chemicals that we can recognize in our surroundings

If for example split a piece of charcoal, which consists of pure carbon, and break it up into its component parts, it will end up as an atom of carbon that will have the same chemical characteristics as the original charcoal If you were to do the same thing of chopping up an iron molecule till it ends up with characteristic component parts, you would end up with iron atoms that behave in similar fashion as the original iron bar If the chopping continues then the iron particles will be broken up into protons, neutrons and electrons.

If on the other hand we took water and started breaking it up into its component parts then we would arrive at the molecules of water wth 2 hydrogen atoms and one oxygen atom. Individually these would not behave like the water molecule but rather like hydrogen and oxygen individually. Then as they get broken up further into electrons protons and neutrons, they will not behave like oxygen or hydrogen but like protons electrons and neutrons.

When a substance consists of a single type of atom it is called an element. There are 92 different elements found naturally on the earth .

A substance that is made up of more than one atom is called a compound.

And atoms of same type link and organize and they form an element

95% of the lipids that we eat and 99% of the lipids in our body are triglycerides

Three fatty acids and a glycerol

All fats are derivatives of fatty acids and glycerol. They, like the carbohydrates are created from a combination of carbon hydrogen and oxygen which link and organize to form a fat soluble compound. The triglycerides consist of one unit of glycerol and three units of fatty acids

The fatty acid is a usually a long chain of even number of carbons (usually between 4 to 28 each carbon allowing for 4 bonds. When there are fewer than 6 carbons it is called a short chain fatty acid. When there are 6-12 carbons it is called a medium chain and when there more than 12 carbons it is called a long chain fatty acids.

Fatty Acid

fatty acid

When the carbons are linked to each other by single bonds then ther are two hydrogens per carbon and the fatty acid is said to be saturated with hydrogen atoms. When there is a double bond between two carbons then each carbon in the double bond only has room for 1 hydrogen each and the fatty acid is unsaturated with hydrogen atoms

70983.4kf09L.1ks01Ls

The unique linking and organization of the carbons hydrogens and oxygen creates unique products or metabolites, This linking is not indiscriminate. There are rules that the units have to abide by in order that organization can take place. An obvious rule in this instance is that the carbon can only mintain 4 bonds A double bond takes up two of the availablke 4 . Since each of the bonded carbons use up 2 bonds with the double bond, and are connected to another carbon on each side and threfore they only have room for one hydrogen each.

Enter another molecule called glycerol ? a type of alcohol with a hydroxyl group on each of its three carbons

Glycerol

Glycerol The OH groups ? hydroxy functional groups place glcerol into the alcohol groups of chemicals ?ol? denotes its alcohol nature diagram http://www.green-planet-solar-energy.com/what-is-glycerin.html

When glycerol links and organizes with with 3 fatty acids a new product is born called triglyceride

Triglycerides

The bond or link of the OH groups on the glycerol side links with the carboxyl group (carboxylic acid) OH + COOH

Proteins

Proteins are polymers constructed from a series of 20 different amino acids. This is the linking part.

An amino acid is composed of an amine linked to an acid

Amine NH3 proteins

Amine NH3 proteins

Alpha Carbon ? The Link

The organizing part is the a specific sequence specified by the gene resulting in the primary structure.

As a result of the specific linking and organizing a secondary structure results which is a specific coiling of the structure in a unique 3D manner There are two basic types of secondary structure The alpha helix and the beta pleated sheet based on the hydrogen bonds that occur at regular intervals

The tertiary structure is a result of linking of side chains of various amino acids

Hemoglobin

Hemoglobin consists mostly of proteins aka the 4 ?globin? chains. The hemoglobin molecule is composed four globular protein subunits. There is an alpha chain (alpha 1 and alpha 2) and a beta chain (beta 1 and beta 2) All the proteins stick together These proteins, are made up of sequences of amino acids. Both proteins must be present to enable the hemoglobin to carry and release oxygen normally. Before birth, the beta protein is not present. Instead a gamma protein is present in the fetus but is replaced by the beta chain at birth. Each protein chain tightly associated with a non-protein heme group. A heme group consists of an iron (Fe) ion (charged atom) held in a heterocyclic ring, known as a porphyrin. The iron ion, which is the site of oxygen and C02 binding In binding, oxygen temporarily oxidizes (Fe2+) to (Fe3+)

Connects cells to each other and form tissues

In the world of language the single and the simple is the letter, while in the world of music and painting it is the note, and the brushstroke respectively. The letter moves on to the word, the note to the bar, and the brush stroke to an object in the painting. In biology the cell is the basis of the organ and organism. The Mozarts, van Goghs, Einsteins and Shakespeare?s of the world, organized connected and integrated the units in such a way so as to create a genius result ? certainly one that is more powerful than the individual parts. In biology, years of evolution have slowly crafted the human body into a miraculous machine which we have the good fortune to own, honor , learn about, and opportunity to unravel and understand its mysteries in the context of the medical world.

The yearning to be ?one? drives us, whether we conciously know it or not. The atom thinks it is indivisible (and probably invincible) but it also has smaller parts. The atom by itself is powerless unless it combines with similar atoms to make up molecule. This same feeling of power and individuality comes to the cell, which for practical purposes, is the smallest living individual and independent unit in biology. It is made up of smaller parts of macromolecules that combine to form microstructures such as the ribosome, endoplasmic reticulum, and the nucleus. All parts in combination make up the cell, giving it singularity and oneness. The cell is powerless without the tissue, and so it combines with similar cells to humble itself before the tissue. Although the tissue claims individuality, it too seeks combination with other tissue as it searches for oneness in the organ. The seeming accomplishment of unity continues through the body to the individual, the family, the community of the village, the community of the nation and the community of the world ? and even the solar system, which bears uncanny structural similarity to the atom. The solar system probably thinks it is the end of the world, but the universe has a surprise in store. At this writing, the universe resides at on the one end and the atom on the other ? both claiming singularity ? but we have to suspect there may be something beyond both of them.

Understanding Physics and Biology Together ? The Goal (a)

Yet is it possible in terms of the motion of atoms to explain how men can invent an electric motor, or design and build a great cathedral? If such achievements represent anything more than the requirements of physical law, it means that science must investigate the additional controlling factors, whatever they may be, in order that the world of nature may be adequately understood. For a science which describes only the motions of inanimate things but fails to include the actions of living organisms cannot claim universality.

Arthur Holly Compton

The Human Meaning of Science (1940), 31.

Understanding Physics and Biology Together ? The Goal (b)

[Certain students] suppose that because science has penetrated the structure of the atom it can solve all the problems of the universe. ? They are known in every ? college as the most insufferable, cocksure know-it-alls. If you want to talk to them about poetry, they are likely to reply that the ?emotive response? to poetry is only a conditioned reflex ?. If they go on to be professional scientists, their sharp corners are rubbed down, but they undergo no fundamental change. They most decidedly are not set apart from the others by their intellectual integrity and faith, and their patient humility in front of the facts of nature?. They are uneducated, in the fullest sense of the word, and they certainly are no advertisement for the claims of science teachers.

Anthony Standen

In Science is a Sacred Cow (1950), 18-19

The Common Vein

Hubble?s observations suggested that there was a time, called the big bang, when the universe was infinitesimally small and infinitely dense. Under such conditions all the laws of science, and therefore all ability to predict the future, would break down. If there were events earlier than this time, then they could not affect what happens at the present time. Their existence can be ignored because it would have no observational consequences. One may say that time had a beginning at the big bang, in the sense that earlier times simply would not be defined. It should be emphasized that this beginning in time is very different from those that had been considered previously. In an unchanging universe a beginning in time is something that has to be imposed by some being outside the universe; there is no physical necessity for a beginning. One can imagine that God created the universe at literally any time in the past. On the other hand, if the universe is expanding, there may be physical reasons why there had to be a beginning. One could still imagine that God created the universe at the instant of the big bang, or even afterwards in just such a way as to make it look as though there had been a big bang, but it would be meaningless to suppose that it was created before the big bang. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job! ? Stephen W. Hawking A Brief History of Time: From the Big Bang to Black Holes (1988), 8-9.

Hemoglobin




Hemoglobin consists mostly of proteins aka the 4 ?globin? chains. The hemoglobin molecule is composed four globular protein subunits. There is an alpha chain (alpha 1 and alpha 2) and a beta chain (beta 1 and beta 2) All the proteins stick together These proteins, are made up of sequences of amino acids. Both proteins must be present to enable the hemoglobin to carry and release oxygen normally. Before birth, the beta protein is not present. Instead a gamma protein is present in the fetus but is replaced by the beta chain at birth. Each protein chain tightly associated with a non-protein heme group. A heme group consists of an iron (Fe) ion (charged atom) held in a heterocyclic ring, known as a porphyrin. The iron ion, which is the site of oxygen and C02 binding In binding, oxygen temporarily oxidizes (Fe2+) to (Fe3+)

The unique linking and organization of the carbons hydrogens and oxygen creates unique products or metabolites, This linking is not indiscriminate. There are rules that the units have to abide by in order that organization can take place. An obvious rule in this instance is that the carbon can only mintain 4 bonds A double bond takes up two of the availablke 4 . Since each of the bonded carbons use up 2 bonds with the double bond, and are connected to another carbon on each side and threfore they only have room for one hydrogen each.

Formation of the Hydrogen Atom




After the big bang one of the first interactions between the electrons and protons was in the formation of the hydrogen atom An electron (unit 1) interacted with a proton (unit 2) in the heated environment in the space of the universe, at a moment in time, and a new and unique unit 3, called the hydrogen atom was formed. because the interaction resulted in a spinning charge an electromagnetic field was set up and the atom also spun in space in a unique way that was not characteristic of either the proton or the electron.
