Consequently, a survey of the Nobel Prizes in Chemistry during this century will provide an analysis of important trends in the development of this branch of the Natural Sciences, and this is the aim of the present essay. Chemistry has a position in the center of the sciences, bordering onto physics, which provides its theoretical foundation, on one side, and onto biology on the other, living organisms being the most complex of all chemical systems. Thus, the fact that chemistry flourished during the beginning of the 20th century is intimately connected with fundamental developments in physics.

Introductio n and Summary Dear readers: I trimmed this essay down to reflect that the essay delves far deeper into many issues that this essay originally covered. My original energy essay was written aroundand could be considered the embryonic version of the version.

If early humans did not learn to exploit new sources of energy, humankind would still be living with its ape cousins in the tropical forests.

Without the continual exploitation of new energy sources, there would have been no civilization, no Industrial Revolution and no looming global catastrophe. Early protohumans migrated from Africa about two million years ago, probably following migrating African predators.

Aboutyea rs ago, anatomically modern humans appeared. By about 10, years ago, humanity had exterminated all the easily hunted large animalsand the hunter-gatherer lifestyle was no longer sustainable on a global basis.

Domestication of animals and food crops led to civilization. Domesticating animals, plants and enslaving humans were the significant activities of early civilizationand ideological indoctrination began in those early days, as the slaves needed to be conditioned to accept their status.

The positions of the new elite classes also needed an acceptable justification. Early agricultural practices also exhausted the landsalthough the dynamic of deforestation, farming, and desertification persists to this day.

In the late 19th century, oil became the next fuel to undergo large-scale exploitation, and its use coincided with amassing capitalistic, monopolistic empires, significantly by United States robber barons, John Rockefeller most notably.

The process of extracting and using fossil fuels is environmentally disastrous. Rapid global warmingmainly caused by burning fossil fuels, is one of the greatest threats that humanity faces today. Every significant industry and profession is largely a self-serving racket, and the larger and more powerful the industry or profession is, the more it resembles an outright racket, which I discovered the hard way during my adventures.

I participated in a significant effort to bring alternative energy to the marketplace, maybe the most significant ever. What happened to the ventures that Dennis Lee headed is a case study of how alternative energy is suppressed. Alternative energy has been systematically suppressed, on a global scale, for the past century, and free energy technology has probably existed for a long time.

The exploitation of energy may exterminate the human species, but it does not have to be that way. If we wake up and begin caring, solving our problems is easy. If we stay asleep, we are doomed.

The problem has a lot more to do with integrity than technology or intelligence. It is up to us. As our star settled into its life, something happened on a tiny fragment that orbits it.

Scientists have developed theories, partly based upon observations, which guess what may have happened a long time ago. The oxygen-hydrogen compound that blankets Earth, known as water, would be a gas instead of a liquid, except for the peculiar way that water molecules are attracted to each otherdue to their electrical polarity.

In the atmosp here is carbon dioxide, which makes up about 0. The fortuitous properties of water and carbon dioxide helped set the stage for something apparently unique in our star system. Today, it is theorized that life began more than three billion years ago on Earth.

For about three billion years, life was largely confined to unicellular organisms, which lived in the ocean.

When the fusion reaction occurs, energy is given off in the form of electromagnetic radiation "ER"called light when it occurs at particular wavelengths.

Light is still an enigma to science, because it seems to be a wave at times and a particle at others. In its wave state, the length of the wave determines how much energy it carries. Radio waves are long waves of ER, and the energy they carry is relatively small.

Introduction

X-rays are short waves, and their relative energy is great. What is called light has a wavelength between those of radio waves and X-rays. The Sun produces ER in a wide array of wavelengths also known as frequencies; the longer the wavelength, the less the frequency, as the velocity is constant.

Also, the Sun shoots out electrons and other subatomic particles at an extremely high velocity. Earth, however, has a magnetic belt called the Van Allen belt and atmospheric layers such as the ozone layer that deflect and absorb much of the high-energy ER that the Sun emits.

An atom is made of a nucleus orbited by electrons. That variable energy level of the electron shell is what makes life possible.Jan 17,  · -Chemical formulas are usually written with an H on the left side of the formula.

A decision needs to be made between right and wrong. I have experienced many ethical dilemmas in my lifetime, so I know that there is no such thing as an ethical dilemma that only affects one person.

The structural formula of a compound indicates a shared pair of electrons by a line between the two atoms; e.g., single covalent bond (H–H), double covalent bond (O=O), and triple covalent bond (N = N).
