Most of the technical and management institutes prefer Wi-Fi facilities in their campus. For that the teachers are now smarter than ever before. Students studying in under graduate & post-graduate class are getting more and more advantage in their study with the use of Laptops and cell phones. The virtual learning environment is going to be more popular day by day. The resources of different subjects like science, engineering and management are sharing their study topic in most interactive manners.
The concept of global Open University is becoming a revolutionary step in total education system of the world. With the lunches of $100 laptop in school levels as a mission could make the whole picture more shining. The audio-video classes make the whole learning process more interesting for the youngsters. PowerPoint slideshows and projectors are not enough. The passion for performing helps the young talents learning any topic very quickly.
Now student can make educational videos with his multimedia phone and upload them in the video sharing websites like YouTube and share them with other friend and teachers. The broadband and other fast connectivity facilities help upload the live videos of class room lectures for the students living other part of the globe. Educations forums and social network are getting a lot of visitors. This proved that they are very essential tool for spreading education. Online teaching is required some special technique of lecturing. In real life classroom the interaction between the students and teacher is more. The course material and textbook everything is available for access. These changes can remove the black board from the classrooms.

New advance technologies are used by human being to modify our lifestyle. People use eyewear not only for fashion but also to protect the eye from the rays coming from the direct sunlight. Eyewear is an obstacle that helps us to correct the vision error in a human eye. This eyewear becomes an obstacle in the living style of a person who can’t do any work without the use of an eyewear. Sometime people use contact leans to solve the refractive error of eye leans. These contact leans are too costly and not affordable by everyone. 
The care of reflective error eyes problem has different solution. The latest development in eye care technology brings by medical science solve the problem of using eyewear for a long time in offices and colleges. Ophthalmologists have invented the surgical treatment of eye to give clear vision to their patient. People are generally afraid of any kind of surgery. It is better to know the testimonial of other patient and the reputation of an Ophthalmologist to do any kind of eye surgery. The lasik is one of the latest developments in solving refractive error of eye. It is one of the safest effective eye treatments according to Ophthalmologists around the world. Under some criteria, a patient can complete the vision correction. The condition are like if the patient has any injury in his or her eye then a doctor generally advice that the patient is unfit for the lasik surgery. Age is also a factor for passing the fitness test. Due to change in the shape of the cornea, people generally face vision error like myopia and farsightedness. Using the laser technology an eye surgeon can change the size of the cornea and the patient can get the normal living.

There is too, considerable danger in pressing for so much practical work in schools. No- one doubts the inestimable value of the laboratory where the child can find out things for himself, or the countryside where he can make his own observations and collect his own specimens; but there is the danger of pressing such practical work to far in favour of the minority who are indeed potential scientists. The tendency here is to ignore science and cultural discipline and treat is almost solely as technology. Practical work cannot, of course, be abandoned altogether since it is essential in order to drive home basic facts and indeed to satisfy the various instincts of the pupil. Furthermore, to inculcate in the school child thee spirit of discovery is all very desirable; but the teacher must maintain a sense of values, realizing that by far the majority of his charges are unlikely to take up science as a profession in later life and that, in any event, many of them thave no learning that way. But science as a social study is a different matter. It is difficult, for example, to see what cultural benefit any boy or girl can derive in later life from an empirical knowledge of the analytical tables or the formula of the water. On the other hand, knowledge of the everyday applications of chemical analysis can have certain cultural repercussions.
The fuller education of the pupils must always be borne in mind. We are not training future scientific specialists and most therefore always keep before us in our teaching the philosophy of science placed in a historical background and above all the impact of science and society.
Our important factor, however, especially in science teaching, must be taken into consideration, and that is the time factor. Teaching hours are comparatively short. If the ideal educational syllabus is to be achieved, however, one must decide what shall be taught and how much of what, and in coming to this decision the dead wood must be cut out and new shoots encouraged. In other words, a more balanced curriculum is desirable, and this must be periodically revised. Therefore, in spite of the time factor, if it can be agreed that a certain thing should be taught in schools, no matter what it is, than time should be found for it.

Rameswaram is a temple city in the southern India. It is actually an island in the sea. There is a township called Dhanuskoti, just 3 km away from Rameswaram. Dhanuskoti is connected to Sri Lanka by a bridge, which almost like a high way and more than 30 km long. According to religious belief the bridge was built by the monkey army of Raja Rama in the age of Ramayana. 
He went to Sri Lanka to rescue his beloved wife Sita, who was kidnapped by Ravana, the Load of Lanka. So, the bridge is mostly known as the Ram setu or nal-setu. 
In 14th century, it was a walking bridge between India and Talai Mannar in Sri Lanka. The US Space organization, NASA had taken some important Photograph of Ram satu and found that there is chunk stones built link between Talai Mannar and Dhanuskoti and it is a partition between Arabian Sea and bay of bangle. In 1804, the British, East India Company renamed the Ramsetu as Adam’s Bridge. Under water the bridge is decorated with nice coral and it is older than 1.75 million years. ISRO said that Ram setu will be one of significant theme of study in India’s Moon Mission in 2008.
There is a lot of debate about the fact that the Ramsetu is a result of human activities in the past or it is completely a natural phenomenon. Another doubtful point is the structure of Ram setu will responsible for any further Tunami in Kerala in future.

The moon is the first place after the earth where man set his foot. It was happened more than 38 years ago. Google announce a world wide contest to earn money by the participation in the contest and the prize money as big as 30 million US $. The contest was announced in 13 September 2007 in SF, USA. To participate in this awful reality show you have to spend just one thousand US $ and you have to walk on the moon surface. To promote the lunar tourism for the general public, it is a fantastic attempt by Google. In the 58th International Astronautical Congress at Hyderabad, Mr. B. SF Alexander made known the truly international contest regarding prize-money and as a privet sector business group they want to make a mark in the promotion of astronautically research. A group of international space scientists are helping Google to discover the winner.
Ex President of India Dr. APJ Abdul Kalama recognize Mars as an alternative habitat for mankind. 
The Indian-Missile-Man was very excited about the innovation of human friendly environment, the opportunity in the space, and alternative energy source in his speech at 58th IAC, at Hyderabad. The space community is optimistic about the rehabilitation of future generation in the Moon or in the Mars. ISRO director Dr. MYS Prasad not interested in mining ores and minerals from other celestial bodies like Mars and Moons, as it is a question of ethic. The NASA has already declared their attempts to send man in the Mars by 2037. We are now entering in the age of space civilization and the international space station is an excellent example of this advancement. Along with this mission, the space research is a vital key point for the advancement of the quality of life in this beautiful planet.
