[www.keralites.net] Was Einstein Wrong? - Law of physics challenged

 

Strange Particles May Travel Faster than Light, Breaking Laws of Physics

"Nothing goes faster than the speed of light" At least, we didn't think so.

New results from the CERN laboratory in Switzerland seem to break this cardinal rule of physics, calling into question one of the most trusted laws discovered by Albert Einstein

 

Discovering how experiments disprove Einstein's Relativity and solving the problems with the Le Sage "graviton" theory reveal subatomic faster-than-light "spheritons" that produce gravity, dark matter, magnetic and electric fields, light, and home for our memories and thoughts.

Discovering new causes of galactic light redshift explains redshift periodicity and shows that the universe is not expanding from a Big Bang.

See the report appended hereunder :
GENEVA (AP) — One of the very pillars of physics and Einstein's theory of relativity — that nothing can go faster than the speed of light — was rocked Thursday by new findings from one of the world's foremost laboratories.

European researchers said they clocked an oddball type of subatomic particle called a neutrino going faster than the 186,282 miles per second that has long been considered the cosmic speed limit.

Tiny particles

The claim was met with skepticism, with one outside physicist calling it the equivalent of saying you have a flying carpet. In fact, the researchers themselves are not ready to proclaim a discovery and are asking other physicists to independently try to verify their findings.

"The feeling that most people have is this can't be right, this can't be real," said James Gillies, a spokesman for the European Organization for Nuclear Research, or CERN, which provided the particle accelerator that sent neutrinos on their breakneck 454-mile trip underground from Geneva to Italy.

Going faster than light is something that is just not supposed to happen according to Einstein's 1905 special theory of relativity — the one made famous by the equation E equals mc2. But no one is rushing out to rewrite the science books just yet.

It is "a revolutionary discovery if confirmed," said Indiana University theoretical physicist Alan Kostelecky, who has worked on this concept for a quarter of a century.

Stephen Parke, who is head theoretician at the Fermilab near Chicago and was not part of the research, said: "It's a shock. It's going to cause us problems, no doubt about that — if it's true."

Even if these results are confirmed, they won't change at all the way we live or the way the world works. After all, these particles have presumably been speed demons for billions of years. But the finding will fundamentally alter our understanding of how the universe operates, physicists said.

Einstein's special relativity theory, which says that energy equals mass times the speed of light squared, underlies "pretty much everything in modern physics," said John Ellis, a theoretical physicist at CERN who was not involved in the experiment. "It has worked perfectly up until now."

Quarks Particles

France's National Institute for Nuclear and Particle Physics Research collaborated with Italy's Gran Sasso National Laboratory on the experiment at CERN.

CERN reported that a neutrino beam fired from a particle accelerator near Geneva to a lab 454 miles (730 kilometers) away in Italy traveled 60 nanoseconds faster than the speed of light. Scientists calculated the margin of error at just 10 nanoseconds. (A nanosecond is one-billionth of a second.)

Given the enormous implications of the find, the researchers spent months checking and rechecking their results to make sure there were no flaws in the experiment.

A team at Fermilab had similar faster-than-light results in 2007, but a large margin of error undercut its scientific significance.


Neutrinos - lightweight, subatomic particles

If anything is going to throw a cosmic twist into Einstein's theories, it's not surprising that it's the strange particles known as neutrinos. These are odd slivers of an atom that have confounded physicists for about 80 years.

The neutrino has almost no mass, comes in three different "flavors," may have its own antiparticle and has been seen shifting from one flavor to another while shooting out from our sun, said physicist Phillip Schewe, communications director at the Joint Quantum Institute in Maryland.

Columbia University physicist Brian Greene, author of the book "Fabric of the Cosmos," said neutrinos theoretically can travel at different speeds depending on how much energy they have. And some mysterious particles whose existence is still only theorized could be similarly speedy, he said.

Fermilab team spokeswoman Jenny Thomas, a physics professor at the University College of London, said there must be a "more mundane explanation" for the European findings. She said Fermilab's experience showed how hard it is to measure accurately the distance, time and angles required for such a claim.

Nevertheless, Fermilab, which shoots neutrinos from Chicago to Minnesota, has already begun working to try to verify or knock down the new findings.

And that's exactly what the team in Geneva wants.

Gillies told The Associated Press that the readings have so astounded researchers that "they are inviting the broader physics community to look at what they've done and really scrutinize it in great detail, and ideally for someone elsewhere in the world to repeat the measurements."

Only two labs elsewhere in the world can try to replicate the work: Fermilab and a Japanese installation that has been slowed by the tsunami and earthquake. And Fermilab's measuring systems aren't nearly as precise as the Europeans' and won't be upgraded for a while, said Fermilab scientist Rob Plunkett.

Drew Baden, chairman of the physics department at the University of Maryland, said it is far more likely that the CERN findings are the result of measurement errors or some kind of fluke. Tracking neutrinos is very difficult, he said.

"This is ridiculous what they're putting out," Baden said. "Until this is verified by another group, it's flying carpets. It's cool, but ..."

So if the neutrinos are pulling this fast one on Einstein, how can it happen?

Parke said there could be a cosmic shortcut through another dimension — physics theory is full of unseen dimensions — that allows the neutrinos to beat the speed of light.

Indiana's Kostelecky theorizes that there are situations when the background is different in the universe, not perfectly symmetrical as Einstein says. Those changes in background may alter both the speed of light and the speed of neutrinos.

But that doesn't mean Einstein's theory is ready for the trash heap, he said.

"I don't think you're going to ever kill Einstein's theory. You can't. It works," Kostelecky said. There are just times when an additional explanation is needed, he said.

If the European findings are correct, "this would change the idea of how the universe is put together," Columbia's Greene said. But he added: "I would bet just about everything I hold dear that this won't hold up to scrutiny."

[www.keralites.net] Green Homes A new concept in House construction

 

The Green Homes is a concept of building homes environment friendly without harming the environment we lived in.  The term green building refers to a construction process and the resulting building structure that is environmentally responsible. The origin of this concept dates back to 1970s in US fuelled by energy crisis and environment pollution. Of late, green buildings have gained prominence with many governments across the world embracing this concept and going in for these structures

The reason for building greener homes is really quite important. We need to live more lightly on the earth, because the degradation of our environment is compromising not only our survival, but the survival of most other living beings on the planet. We can no longer ignore the impact we have on the earth's ecosystems. The way we live, the choices we make in providing for our needs, will have an enormous influence on the quality of life of those who will follow us. Now is the time to take responsibility for the consequences of our life styles. Green buildings bring in techniques like use of natural lighting through efficient use of sunlight, green roofs for preserving rain water and so on. Use of non toxic materials in the construction and ample ventilation helps residents enjoy a healthy life indoors. The energy use which these structures help in bringing down is tremendous. Experts say that these structures consume 40% less energy with the efficient use of available resources as compared to normal structures which consume huge amounts of energy causing harm to the environment. The green homes are able to do this by concentrating on alternative energy sources like solar, wind energy and biomass.

How we build our homes, both in design and choice of materials, is one of the most significant ways that we can affect our future. Much of the concern boils down to the use of energy. How much energy is embodied in the building materials themselves, in their transportation and assembling? Then once the house is built, how much energy does it consume to keep its inhabitants comfortable? Consumption of energy has a direct influence on environmental quality, because of the inherent pollution through greenhouse gasses and other emissions. Then there is the loss of natural beauty, ecosystems and basic resources associated with the extraction of fossil fuels and building materials. The combined effect of this is staggering.

 
Residents enjoy lifelong benefits by opting for a green home as the cost of construction of a green home is comparable or rather cheaper than a conventional home. Not only that, the residents also enjoy lesser energy and water consumption due to the best practices adopted. Green Homes are also making headway into Kerala which has an educated population that understands the environmental impact and are looking for alternate viable solutions. Designers and architects these days are incorporating such concepts while building the homes, to make green homes a reality

[www.keralites.net] How Indian Doctors Loot Patients..

 

This is from Dr. B M Hegde. 
  
Wonder how much is widespread and how much are merely a few black sheep. 
  
How Indian Doctors Loot Patients. 
  
  
Most of these observations are either completely or partially true. Corruption has many names, and one of civil society isn't innocent either. Professionals and businessmen of various sorts indulge in unscrupulous practices. I recently had a chat with some doctors, surgeons and owners of nursing homes about the tricks of their trade. Here is what they said 
  
1)      
40-60% kickbacks for lab tests. When a doctor (whether family doctor / general physician, consultant or surgeon) prescribes tests - pathology, radiology, X-rays, MRIs etc. - the laboratory conducting those tests gives commissions. In South and Central Mumbai -- 40%. In the suburbs north of Bandra -- a whopping 60 per cent! He probably earns a lot more in this way than 
the consulting fees that you pay. 

2)      
30-40% for referring to consultants, specialists & surgeons. When your friendly GP refers you to a specialist or surgeon, he gets 30-40%. 

3)    
  30-40% of total hospital charges. If the GP or consultant recommends hospitalization, he will receive kickback from the private nursing home as a percentage of all charges including ICU, bed, nursing care, surgery. 

4)      
Sink tests. Some tests prescribed by doctors are not needed. They are there to inflate bills and commissions. The pathology lab understands what is unnecessary. These are called "sink tests"; blood, urine, stool samples collected will be thrown. 

5)     
 Admitting the patient to "keep him under observation"People go to cardiologists feeling unwell and anxious. Most of them aren't really having a heart attack, and cardiologists and family doctors are well aware of this. They admit such safe patients, put them on a saline drip with mild sedation, and send them home after 3-4 days after charging them a fat amount for ICU, bed charges, visiting doctors fees. 

6)     
 ICU minus intensive care. Nursing homes all over the suburbs are run by doctor couples or as one-man-shows. In such places, nurses and ward boys are 10th class drop-outs in ill-fitting uniforms and bare feet. These "nurses" sit at the reception counter, give injections and saline drips, perform ECGs, apply dressings and change bandages, and assist in the operation theatre. At night, they even sit outside the Intensive Care Units; there is no resident doctor. In case of a crisis, the doctor -- who usually lives in the same building -- will turn up after 20 minutes, after this nurse calls him. Such ICUs admit safe patients to fill up beds. Genuine patients who require emergency care are sent elsewhere to hospitals having a Resident Medical Officer (RMO) round-the-clock. 

7)      
Unnecessary caesarean surgeries and hysterectomiesMany surgical procedures are done to keep the cash register ringing. Caesarean deliveries and hysterectomy (removal of uterus) are high on the list. While the woman with labour -pains is screaming and panicking, the obstetrician who gently suggests that caesarean is best seems like an angel sent by God! Menopausal women experience bodily changes that make them nervous and gullible. They can be frightened by words like " and "fibroids" that are in almost every normal woman's radiology reports. When a gynaecologist gently suggests womb removal "as a precaution", most women and their husbands agree without a second's 
thought. 

8)      
Cosmetic surgery advertized through newspapers. Liposuction and plastic surgery are not minor procedures. Some are life-threateningly major. But advertisements make them appear as easy as facials and waxing. The Indian medical council 
has strict rules against such misrepresentation. But nobody is interested in taking action. 

9)       
Indirect kickbacks from doctors to prestigious hospitals. To be on the panel of a prestigious hospital, there is give-and-take involved. The hospital expects the doctor to refer many patients for hospital admission. If he fails to send a certain number of patients, he is quietly dumped. And so he likes to admit patients even when there is no need. 

10) 
 "Emergency surgery" on dead bodyIf a surgeon hurriedly wheels your patient from the Intensive Care Unit to the operation theatre, refuses to let you go inside and see him, and wants your signature on the consent form for "an emergency 
operation to save his life", it is likely that your patient is already dead. The "emergency operation" is for inflating the bill; if you agree for it, the surgeon will come out 15 minutes later and report that your patient died on the operation table. And then, when you take  delivery of the dead body, you will pay OT charges, anaesthesiologist's charges, blah-blah- 

Doctors are humans too. You can't trust them blindly. Please understand the difference. 

Young surgeons and old ones. The young ones who are setting up nursing home etc. have heavy loans to settle. To pay back the loan, they have to perform as many operations as possible. Also, to build a reputation, they have to perform a large number of operations and develop their skills. So, at first, every case seems fit for cutting. But with age, experience and prosperity, many surgeons lose their taste for cutting, and stop recommending operations. 

Physicians and surgeons. To a man with a hammer, every problem looks like a nail. Surgeons like to solve medical problems by cutting, just as physicians first seek solutions with drugs. So, if you take your medical problem to a surgeon first, the chances are that you will unnecessarily end up on the operation table. Instead, please go to an ordinary GP first
