You know when you put ground pepper ontop of water in a dish.

The pepper floats on top, covering the water. But when you put some dishwater soap on your finger and stick it in the middle of the dish, The pepper moves away from the finger.

How do you explain this in terms of chemistry and physics?

The answer is on this site:

http://www.newton.dep.anl.gov/askasci/gen06/gen06174.htm

The "simple" answer is that the surface tension of the pepper particles is less than "pure" water (about 72 ergs/cm^2), so the pepper particles tend to float on the water’s surface. When you add a drop of soap, you greatly reduce the surface tension of the water near the point at which you add the soap. Initially, this causes a repulsion of the pepper particles and the particles tend to follow the high surface tension areas. If you shake the solution, you will find that the pepper particles get "wetted" by the soap solution and the pepper will disperse in the soap solution.

From the desk of Dr Magne, author with Wallace D. Wattles of the Science of Being Well Home Study Course.

A range of remarkable healers at The Art and Science Of Energy Healing conference shared extraordinary techniques that have even healed a paraplegic. Some of these techniques were discovered and discussed many years ago by Wallace D. Wattles, the author of The Science of Getting Rich and the Science of Being Well.

An energy practitioner demonstrated secret techniques that enabled her to carry out a remarkable healing of a

person with spinal paraplegia caused by an aortic dissection who was paralyzed from the T6 vertebrae,

which controls nerves to the chest. After six months of applying the techniques, the patient was re-evaluated and found to have feeling above his lower leg muscles and the even sacral nerves, which control his bowel and bladder.

This exceptional case is in the process of being written up in the medical journals.

Using the full spectrum of healing techniques, it is now possible to:

• Run a ‘current’ of energy between the pineal and the pituitary in the brain, which creates a special charging effect enabling you to perceive layers of The Field

• Develop techniques so that you can perceive the difference between energy body from someone else’s.

• Charge and increase your own energy after balancing

These exciting developments which are now coming to the fore of many conferences and healing workshop have their origins in Age old techniques. Wallace D. Wattles was one of the first writer and practitioner to describe the power of the mind http://www.thescienceofbeingwell.biz/as it applies to create wealth as well as health. He is better known for divulging the secrets of creating wealth, since this has universal appeal.

However, his methods can be applied just as effectively to creating abundant health. The Home Study Course gives you a series of step-by-step procedures that take only minutes of your time to bring yourself back to long-lasting Health. The Course contains clear instructions.

I m a physics undergrad with a major interest in astrophysics and space technology and I m not found of Chemistry at all.The question is for those of you who are at least grad student or higher . I m quite F level in Chem.and the worst of it is that I can hardly force myself to dig deeper in Chem.Thanks!

Um, look around here and see if you like this much chemistry.

Actually, more superstition than you would imagine.

The science part, we all know. By application of laws, theories, and technologies borrowed from physics, biochemistry, and engineering, veterinary medicine takes on the appearance of a science.

But, surely, mere application of scientific principles does not make an enterprise a science. After all, belief systems of all kinds use scientific principles. Religions apply the principles of economics, engineering, and more. But no one would confuse religion with science.

A science is a coherent system that produces consistent outcomes. Orthodox veterinary medicine has value, but it is neither coherent nor consistent.

The lack of consistency is obvious. Anyone having an animal treated at a vet knows that the outcome is chancy. Maybe the treatment will work and maybe it won’t. Vets make no excuses for this lack of certainty and everyone, including myself, accepts it. Animals are extraordinarily complex creations and no one should expect predictable results.

The lack of coherence, though, is another matter. After all, we expect any credentialed group, especially one authorized to deal in sickness and Health to have a logical coherence. We expect their facts to be part of a real, objective analysis. Many of the “facts” of veterinary medicine are not facts at all.

A complete analysis of the logical flaws in veterinary medicine would take a much longer article and will be dealt with in the future. However, their most flagrant disregard for reality has to be the reliance upon disease entities.

Disease entities do not exist! At least they do not exist in the way that we ordinarily understand a thing to exist. Things, entities, objects have a mass that can be measured and weighed. Diseases do not have extension in time or space. There is no there there. They have no factual basis. Disease entities are a focus for treatment, a shorthand notation to explain a complex biological process.

No problem with veterinarians using shorthand to focus their treatments. The problem arises when a convenient way of talking about a condition takes on a life of its own. The problem arises when we start to confuse the label of a disease entity for the reality of a disease process.

Take for an example, Parvo in dogs. What is it? It is not the Parvo Virus. The Parvo Virus existed before 1984. But Parvo, the disease, did not. Before 1984, dogs contracted the Parvo Virus but most of them did not contract Parvo, the disease.

Even today, most unvaccinated dogs contracting Parvo will recover. Some, though, will die within 24 hours. The virus is the same. The dogs are different. Parvo, and all diseases, describe a complex response between host and pathogen. Parvo is not a thing. It is a process.

Facts are stubbornly solid. They have a solidity that superstitions lack. So the veterinarian inability to affect the immune strength of dogs is a fact that should be addressed but for many reasons is not. So since the vets lack the tools, they do not talk about treatments for immunity. In its place, they substitute an imaginary enemy they can deal with–the disease of Parvo.

Parvo, a non-existent entity, can be conquered with a vaccine, itself a very dangerous treatment. That would be acceptable except the Parvo was never there to begin with. What happened with the advent of modern veterinary medicine was that dogs were getting immunologically weaker. One treatment the vets devised for that immunological weakness was to initiate an immune response to the Parvo virus. The result of the Parvo vaccination, and the many other vaccinations, is that while dogs are now immune to Parvo and other common canine diseases, their overall immune strength continues to fall as they get sicker and sicker.

Now dogs are free of the common canine diseases. Only, they get more immune-related diseases than ever. Dogs are diabetic, cancerous, dyspeptic, allergic, and inflamed. The vets focused on disease entities rather than on the interaction of a pathogen and the host. The result is a domestic canine population more immune to a narrow spectrum of diseases and more susceptible to a much wider spectrum.

Superstition, especially the kind that denies the facts underlying sickness and health, is counter-productive. Superstition does have a positive value, though. It is a tool of the powerful against the powerless. When diseases became things, medically authorized persons gained a great deal of power but lost their credibility, effectiveness, and scientific legitimacy.

I was thinking about doing a medical degree to become a doctor. The thing is I’m great at remembering things and working out how the body works etc and I have an analytical mind, but I’m not that good at maths or chemistry. If I can pass the university and get the degree, will that be enough or do you need to be inately talented at maths and chemistry?

you don’t need to be great at math or chem…. you have to be good at biology and memorizing mountains of information

I know that chemistry is a very personal concept and varies between all kinds of people. And I know that you generally have common interests or ideas about certain things (usually) that draw you to a certain person. And sometimes, you just don’t know why you’re drawn to a certain person and why they’re drawn to you, but that’s just how it plays out.

So my question is, how do you define good chemistry? What are the characteristics of people who feel chemistry between each other? And 10 points for anyone who can answer why exactly people feel chemistry in the first place, biologically, mentally, emotionally, spiritually, etc.

I know it seems like a lot to answer but I am a very curious girl and want to know! All answers are totally appreciated. Thanks for taking the time to read my ridiculous question and hopefully leaving a helpful answer:).

.Personally I think in any partnership,you both have to stimulate the relationship and be willing to change with changing circumstances. Nothing is constant.It’s all about compatibility,respect, honour and equality

Here’s an adventure in perfume scent – science secret smell revealed! You’ll discover why. So, let’s begin at the beginning…
The science of perfume is thousands of years old.

The word “perfume” comes from the Latin word per fume “through smoke”. The first form of perfume was incense, and it was first discovered by the Mesopotamians about 4,000 years ago. However, the Egyptians were the first to incorporate perfume into their culture followed by the ancient Chinese, Hindus, Israelites, Carthaginians, Arabs, Greeks, and Romans.

One of the oldest uses of perfumes comes from the burning of incense and aromatic herbs used in religious services. This very often comes from the aromatic gums, frankincense and myrrh, gathered from trees. The ancient people often soaked the fragrant woods and resins in water and oil, and rubbed their bodies with the liquid. They also embalmed the dead with these perfumes.

With the advances in organic chemistry, synthetic perfume products were first produced in the late 19th century. And, many new scents soon came into the market.

Grasse in Provence, France became a centre for flower and herb growing for the perfume industry. In the same area, men who treated leathers found themselves smelling so badly that they perfumed themselves and the leathers. Thus, they became knowledgeable about making botanical essences and they subsequently became the early perfume noses. But it was only in the 20th century that scents and designer perfumes were really mass produced. Way before that, the few trade names that existed were Coty and Yardley who made fairly light scents with familiar smells.

Perfume is made from about 78% to 95% of specially denatured ethyl alcohol and a remainder of essential oils. With the advances in science, human euphoria perfumes and colognes soon came into the market. These are scientifically engineered pheromone concentrate that has proven effects on attracting the opposite sex. Just as animals use scents to attract others, humans possess the same senses which are potent for sexual attraction!

In creating Human Euphoria Pheromones, pure pheromones are added to essential oils that produce a scent designed to immediately attract the opposite sex. Some companies use 99.99% pure reagent-grade product and contain a combination of both Androstenone and Androstenol pheromones designed to create an incredibly powerful sexual attraction.

However, perfume smell is not the only thing that attracts the opposite sex. Studies show that men associate the scents of cinnamon and vanilla with love. Cinnamon was believed to be an aphrodisiac. And thus, to attract your man, try baking cinnamon rolls before a date, or simply wear a cinnamon-vanilla scented perfume.

On the other hand, women are attracted to a black licorice scent. So men, go eat your licorice!

In this little adventure in perfume scent – science secret smell revealed, we have covered a short history of perfume and the science behind it.
