Greek physics

Several kinds of physical theories emerged in ancient Greece, including both generalized hypotheses about the ultimate structure of nature and more specific theories that considered the problem of motion from both metaphysical and mathematical points of view. Attempting to reconcile the antithesis between the underlying unity and apparent multitude and diversity of nature, the Greek atomists Leucippus (mid-5th century bce), Democritus (late 5th century bce), and Epicurus (late 4th and early 3rd century bce) asserted that nature consists of immutable atoms moving in empty space. According to this theory, the various motions and configurations of atoms and clusters of atoms are the causes of all the phenomena of nature.

In contrast to the particulate universe of the atomists, the Stoics (principally Zeno, of Citium, bridging 4th and 3rd centuries bce, Chrysippus [3rd century bce], and Poseidonius of Apamea [flourished c. 100 bce]) insisted on the continuity of nature, conceiving of both space and matter as continuous and as infused with an active, airlike spirit—pneuma—which serves to unify the frame of nature. The inspiration for the Stoic emphasis on pneumatic

Physical Science

physic

Physical science, the systematic study of the inorganic world, as distinct from the study of the organic world, which is the province of biological science. Physical science is ordinarily thought of as consisting of four broad areas: astronomy, physics, chemistry, and the Earth sciences. Each of these is in turn divided into fields and subfields. This article discusses the historical development—with due attention to the scope, principal concerns, and methods—of the first three of these areas. The Earth sciences are discussed in a separate article.

Physics, in its modern sense, was founded in the mid-19th century as a synthesis of several older sciences—namely, those of mechanics, optics, acoustics, electricity, magnetism, heat, and the physical properties of matter. The synthesis was based in large part on the recognition that the different forces of nature are related and are, in fact, interconvertible because they are forms of energy.

The boundary between physics and chemistry is somewhat arbitrary. As it developed in the 20th century, physics is concerned with the structure and behaviour of individual atoms and their components, while chemistry deals with

How to Make Writing Become Completely Easy to Deal with

What will you do whenever you face difficulties in completing your writing assignments? Well, basically, different people may have different solutions. It is very possible for you to think that you will ask the help from the other people to take care of the writing for you. You can ask the help from your elder brother or sister or even your parents.

Improve Child Development by Joining the School Science Workshops

Workshops of any sort are fun and instructive because you don’t feel the strain of learning and yet you are imbibing quite a lot. An engaging learning environment comes with all the paraphernalia that you want—flexibility, stimulation, freedom—-and much more. Children love workshops better than classrooms and that’s not to be wondered at!! So school science workshops are the icing on the cake for them as they prefer to learn by doing and seeing.

What do they do?

School science workshops help in child development as their little minds work in the way they want them to. In fact, going a step further, rather than being taught in the stuffy environs of the classroom, they take charge of how they learn and what they learn. This makes them more focused in their approach as they are exercising their gray cells all the time.

Nothing can equal learning first hand and by personal experience—children become better learners this way, they understand faster and they learn to think for themselves. Each child’s mind operates in a different way and takes a different path and workshops are a great place to tease those gray cells and discover

Environment for Brain Development: The Impact of School Set up on Infants and Toddlers

The importance of the physical environment in which children are given an opportunity to learn the basic skills of life, is that the design of the learning arena should be such that it encourages children in engaging in explorations that are self driven and not directed by others. In simple words, children should not only feel comfortable in the given environment but should be so much at ease that they would be motivated to be their own drivers. If the physical environment is not directed at supporting the development of infants, chances are that the infants and toddlers would waste their time by engaging in activities directed by the teacher or simple wander aimlessly, thereby wasting the learning opportunity. When infants are not properly engaged, it can lead to aggressive behavior with the teacher behaving like a policeman most of the time.

A Brief Guide To Basic Science Essay Writing

Your science paper will usually have to be divided into sections, and the sections will differ depending on what type of science essay you are writing and the level at which you are writing it. Here is a brief outline of each section, though you should check with your professor to find out the most desired structure.

Research Methodology

You need to show what research methods you used. You need to pick an approved process and then justify why you picked it. You need to explain why it is the right process for the job. You need to do a similar thing if you are writing a research paper.

Introduction

You need to keep this section very concise as you may use the rest of your paper to fully explain your essay.

Hypothesis

The hypothesis is usually nestled somewhere within your introduction. It is usually a question you are aiming to answer or it details

Virginia Researchers See Promise in ‘Synthetic Biology’

The phrase “synthetic biology” may sound like science fiction, but a small group of biology students at the University of Virginia say this field will play an important role in our lives over the next few years.
Scientists in the field are finding ways to produce cheap anti-malarial drugs, use bacteria to clean up chemical waste and reduce resistance to antibiotic drugs.
In the future, people could be eating vanilla and cheese produced from yeast or using laundry detergent and makeup derived from algae.
“It’s something we’re going to see a lot more of,” said Tom Moss, a second-year biology major. “(And) there’s a lot of misconceptions about it.”
[SPECIAL REPORT: STEM Solutions]
Moss is in a small group of students and faculty members who organized a recent public meeting on synthetic biology at UVa’s OpenGrounds building. Their goal is to help the public understand the importance of this field.
Synthetic biology is related to — but not synonymous with — genetic modification. While genetic modification may involve replacing or changing individual genes within an organism, synthetic biology involves far more extensive changes such as completely re-engineering the genomes of microorganisms to create “designer” proteins or engineer viruses to attack

Plastics’ Chemical May Affect Baby Boys’ Genital Development

Exposure to a common plastics’ chemical during pregnancy may have effects on genital development in baby boys, a small study hints.

Researchers found that baby boys born to moms with greater exposure to a chemical called DiNP tended to have a shorter anogenital distance — the space between the genitals and anus. Anogenital distance is set in the womb, and it’s considered a marker of exposure to androgens (“male” hormones) during pregnancy.

The researchers said their findings, published online Oct. 29 in Environmental Health Perspectives, add to concerns about the possible effects of certain plasticizers on the male reproductive system.

But the authors also acknowledged that the study points to a correlation between DiNP and boys’ anogenital distance — and not necessarily a cause-and-effect relationship.

“We need more studies,” said Shanna Swan, a professor of preventive medicine at the Mount Sinai School of Medicine in New York City. “This is one study of a small number of boys.”

Still, she said the findings are in line with some research on certain other chemicals in the same group — known collectively as phthalates.

Phthalates are added to plastics to make them more flexible and difficult to break. They

Race, Ethnicity Affect Breast Cancer Survival, Study Shows

Your chances of being diagnosed with early breast cancer, as well as surviving it, vary greatly depending on your race and ethnicity, a new study indicates.

“It had been assumed lately that we could explain the differences in outcome by access to care,” said lead researcher Dr. Steven Narod, Canada research chair in breast cancer and a professor of public health at the University of Toronto. In previous studies, experts have found that some ethnic groups have better access to care.

But that’s not the whole story, Narod found. His team discovered that racially based biological differences, such as the spread of cancer to the lymph nodes or having an aggressive type of breast cancer known as triple-negative, explain much of the disparity.

“Ethnicity is just as likely to predict who will live and who will die from early breast cancer as other factors, like the cancer’s appearance and treatment,” Narod said.

In his study, nearly 374,000 women who were diagnosed with invasive breast cancer between 2004 and 2011 were followed for about three years.

The researchers divided the women into eight racial or ethnic groups and looked at the types of tumors, how aggressive the

‘Metabolizer Test’ Might Someday Take Guesswork Out of Quitting Smoking

Quitting smoking is notoriously tough, and some smokers may try different approaches for years before they succeed, if ever.

But new research suggests that someday, a simple test might point smokers toward the quitting strategy that’s best for them.

It’s been long theorized that some smokers are genetically predisposed to process and rid the body of nicotine more quickly than others. And now a new study suggests that slower metabolizers seeking to kick the habit will probably have a better treatment experience with the aid of a nicotine patch than the quit-smoking drug varenicline (Chantix).

The finding is based on the tracking of more than 1,200 smokers undergoing smoking-cessation treatment. Blood tests indicated that more than 660 were relatively slow nicotine metabolizers, while the rest were normal nicotine metabolizers.

Over an 11-week trial, participants were prescribed a nicotine patch, Chantix, or a non-medicinal “placebo.”

As reported online Jan. 11 in The Lancet Respiratory Medicine, normal metabolizers fared better using the drug compared with the nicotine patch.

Specifically, 40 percent of normal metabolizers who were given the drug option were still not smoking at the end of their treatment, the study found. This compared with just 22 percent

Dengue protein modulates human enzyme: Fuel for replication

Dengue is a mosquito-borne tropical disease currently endemic in more than 10 countries. According to the World Health Organization, 390 million people are infected by dengue every year.

 

The disease can be caused by one of the four types of dengue virus transmitted by the Aedes aegypty mosquito, the main vector for dengue. In humans, symptoms of dengue infection include fever, headache, muscle and joint pain and a characteristic skin rash. In some cases, dengue infection can take a dangerous turn and develop into a life-threatening hemorrhagic fever and dengue shock syndrome.

A tetravalent vaccine that could protect against all four types of dengue virus is not available–and neither is one that could protect against a single type, for that matter. What is more, no specific treatment against dengue exists. Thus, researchers have sought strategies to reduce mosquito habitat or replication. Unfortunately, none of the approaches developed so far has been successful in eradicating the disease or diminishing the odds of being bitten by the mosquito.

NS1 is one of the seven nonstructural proteins composing the dengue virus and more specifically its replication machinery. It is an abundant protein detected in the serum of infected patients and used as a
