These incandescent light bulbs, though helped the world coming out of darkness but they are constantly destroying the environment.
After a lot of research, scientists came out with one good alternative option to these traditional light bulbs. CFL( compact fluorescent light bulbs) are much more energy efficient and do not have any negative effect on the environment like the traditional bulbs. But in spite of knowing all the benefits of these CFL’s, people are still not limiting the use of those harmful traditional bulbs.
We all know that lighting plays a very important part in our lives. Around 15% of the total electricity produced is used to provide sufficient light. And from this 15% a major part is wasted as it is consumed by the inefficient incandescent bulbs. Since, today there is a great usage of lighting fixtures everywhere, the increased use of incandescent bulbs is adding to climatic destruction like global warming.
The major disadvantage of traditional light bulbs is that, they are not at all energy efficient sources and are also effecting the eco system. In addition to that the light produced is too dim. So, these reasons should be sufficient for anyone to limit their usage and help protect the environment as finally we would be the sufferers.
According to a research, an incandescent bulb converts only 5% of the energy consumed into light wasting the rest of it whereas a CFL, can almost produce the same amount of light as the energy consumed so saving up to 80% of energy. So, it is clearly evident that CFL is a far better option than the traditional bulbs.
The Essay on Photoelectric Effect Light Metal Energy
Photoelectric Effect Photoelectric Effect is the formation and liberation of electrically charged particles in matter, usually metals, when it is irradiated by light or other electromagnetic radiation. The term photoelectric effect designates several types of interactions. In the external photoelectric effect, electrons are liberated from the surface of a metallic conductor by absorbing energy ...
CFL’s apart from being energy efficient sources, live for a…

n this fast changing world, problems in almost all fields of human endeavor have to be solved and resolved on scientific bases. The influence of decisions based on quantitative information has never been more evident than in the present decade especially with the use of modern technology. Indeed, the growing complexities of the activities and functions of the various fields of endeavor have made the use of statistics imperative.
However, one major problem among statisticians, under a given circumstance and budgetary constraints, is the production of reliable data due to built-in biases of the collectors and/or respondents.
In many cases, the main cause of failure in any research undertaking is the wrong choice of method in the collection of data. This is especially true in the case of survey. While the confidence level can be established as basis for accepting the representativeness of the samples, and variability can be computed for estimating probable sampling errors, it is virtually impossible to do the same due to errors introduced through bias either positively or negatively.
Perhaps the most important point to remember is that, despite the formidable arrays of formulae, statements of confidence, and tests of significance, the quality of data collected is the most important aspect of any survey. The information generated by statistical manipulation can only be as good as the data upon which it was based. The adage “Garbage In, Garbage Out” (Smith, 1981), therefore, should be borne in mind when designing surveys and gathering data, so that the processing of the data will bear useful results.
According to me, science is a boon only and it depends on the users. The invention of equation e=mc^2 paves way for the destruction of two countries. Lots and lots of million of poeple destroyed in this. But this plays much in solving energy crisis. Nowadays automobiles, vehicles makes our life comfortable in moving but at the same time, pollution destroys the ozone and creates major problem. By considering this we say, to solve this kinds of problem alsoa new scientific advancement paves a new way.
The Research paper on Critical Thinking and Problem solving
Numerous decisions are taken every day. People choose when to get up on a certain morning, what clothing to wear, and whether to read a particular book. Most of the decisions made throughout the day are relatively trivial or inconsequential. It probably does not matter too much if it is decided to sleep an extra 15 minutes on a certain morning or if a blue shirt is selected rather than a green ...
The overt observation of some knowledgeable persons who passionately feel concerned for the welfare of humanity, in the wake of scientific strides and technological triumphs, laments that “technology creates more problems than it solves”. Their concern echoes the similar sentiments of thinkers like J.G.Ballard for whom, “technology dictates the languages in which we speak and think. Either we use those languages or we remain mute”, and for Omar Bradley “our technology has already outstripped our ability to control it”. Despite these jarring notes, technology has acquired a halo that is almost impossible to shake off.
Who can deny the robust role and range of technology that we experience in our every day life. If we care to look at the scintillating side of technology, we find space technology and its applications provide useful data for natural disaster monitoring, solving environment problems, improve telecommunications and provide other basic services. Through fax, e-Mail and the Internet, information technology has outstripped all barriers that time and space had placed in man’s search for instant information. Though electronic information is hard to control, yet the individual newsgatherer is visible and vulnerable. The latest in the success story is the likely boom that bio-technology promises to unfold in the years to come. Rightly, biotechnology is being seen by scientists and entrepreneurs alike as the next big thing with the potential to revolutionise the fields of agriculture, health and medicine. The promises are many: disease-resistant and high-yield crops that could solve the world’s food problems; new medicines and drug delivery systems to cure diseases and prevent genetically inherited disorders; and new enzymes that make industrial production more efficient and cost-effective.

He has since been working as a trading systems analyst, standardized test item developer, and freelance writer. As a freelancer, he has written articles on everything from personal finances to computer technology. Forensic science involves the use of scientific procedures to ...
As the given topic is science is boon or bane. I can say it depend upon people in what way they use the science. We can take many example like in olden days if we wanted to travel or when we had to visit any place or any message we had to conve it was taking a day, a month, sometime a year also but now a days due to science it is possible only in second or maximum in a day. If you take in the field of medical science, in olden days anybody was suffering with any disease either they could recover with Ayurveda treatment or depends on a god blessing but now a days for every disease a special instruments, equipment is present to handle the disease like ECG
Science has also done a lot to clean, beautify and illuminate our houses and cities. Our city streets are paved, illuminated and well-drained. We have water supply system that provides clean water for household use. The dirty water is carried through sealed pipes to disposal plants. Iron, steel, aluminium and even glass can be moulded and given different shapes to suite our need and taste. In our houses we have refrigerators to keep our food fresh for months, air–conditioners and heaters to change climate according our choice and many other machines that cook our food, clean our houses and wash our clothes
