Science learning centres in all Districts

KATHMANDU: Minister for Science and Technology Kalpana Dhamala informed that works are being carried out in line with the government's policy to set up science learning centres across all the districts. Minister Dhamala said this while inaugurating 19th anniversary of National School of Science on Sunday. 'People's dream of building prospered Nepal will be cherished only when the state put the sector of science on priority', she added. On the occasion, boys and girls students securing highest scores in the examinations conducted by the campus were given away medals, awards and certificates. Campus Founder Principal Madhab Prasad Baral admitted that brain drain of students is caused due to failure of private education institutions in delivering quality education. There are 1,975 students in...

Google's Self Driving car

As the researches on artificial intelligence is being growing rapidly, the engineers of Google developed a self driven car. We can say that self driven car is the one more forward step in the field of artificial intelligence.Their cars use cameras, radar sensors and laser range finders to “see” and guess what, they’ve teamed up with the winners of the DARPA challenge, an academic competition to create a self driven car.They’ve been testing their automated cars for a long time – 140,000 miles of travel logs. And Google has been able to make this possible because of their data centers – the massive computers that they have.They think cars were invented at the wrong time – when computers weren’t widespread. It just makes sense that cars drive...

Semiconductors

Semiconductors, the foundation of the modern electronics including many helpful communicating devices such as radios, TV, cell phones etc is a material with electrical conductivity due to electron flow intermediate in magnitude between that of a conductor and an insulator. The conductivity of semiconductor lies in the range of 103 to 10-8 Siemens per centimeter. The common semiconductors are the crystalline solids which include hydrogenated amorphous silicon and mixtures of arsenic, selenium and tellurium in a variety of proportions. Silicon is used to create most semiconductors commercially. A pure semiconductor is often called "intrinsic" semiconductor. The added materials in intrinsic semiconductor to make them with desired conducting capacity...

Robotics

A robot is a mechanical intelligent agent which can perform task on its own, or with guidance. In practice the robot is usually an electromechanical machine which is guided by computer and electronic programming. At first the machines was initially used for simple household tasks such as water lifting, grinding etc. But with the development of advanced technology robots are become more complex and can solve many hard problems. In development of robot we find Niko Tesla designing a radio controlled torpedo. Gakutensoku, which cried and changed its facial expressions. The first electronics robot created by William Grey Walter in Bristol, England, in 1948 made an evolution on robots history. The ultimate, 1954 was the digital and programmable...

Sonar

A technique that uses sound propagation to navigate, communicate with or detect other vessels is sonar, originally an acronym for Sound Navigation And ranging. There are two technologies that share the name sonar. Passive sonar is essentially listening for the sound made by vessels, active sonar is emitting pulses of sound and listening for echo’s. As a historical evidence of sonar we take Leonardo da Vinci who recorded a ultrasonic sound by inserting a tube in 1940.           Sonar may be used as a means of acoustic location and the measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of RADAR. Sonar may also be used in...
