The Earth has enough resources to generate electrical energy for several billion years! How does it sound? Unbelievable; especially in the light of growing debate over issues like depleting source of fossil fuel and its adverse effect on environment. Well, believable , this book says. The amazing technologies discussed in the book prove beyond doubt that it indeed can be done. Fuel cells, geothermal energy and tidal energy are practically inexhaustible sources of ...
Something you have - A key or a token; something you know ? A password or a PIN; and something you are – Biometric.Biometrics is a method of identification and verification based on individual physical traits. Thus, one’s fingerprints, one’s face, one’s iris can all be biometric identifiers. Why Biometrics? Because, unlike a key or a token, a biometric identifier cannot be stolen or lost; it remains with an individual. Unlike a password or a PIN, it ...
Prima facie, there seems to be no similarity between biology and information science. Yet, bioinformatics is one of the most happening disciplines now. It combines biological knowledge with computational tools. Biological molecules are immensely large and incredibly complex! Describing them in terms of worksheet requires a large number of fields.Human genome project has amassed tremendous amount of data. The challenge now lies in deriving knowledge out of this ...
You regularly use credit card to shop and dine. You pay your bills regularly. One day, you experience a shock of life to see an astronomical bill. After enquiry, you learn that your identity is stolen. Someone else has purchased goods! Sounds unbelievable? It is not! Incidences like this occur fairly regularly in markets such as the US and the UK. Now, they are assuming alarming proportions in India too! The crooks exploit the vulnerabilities in the system and ...
How are pilots trained? What technology is responsible for stunning realism in games? How are virtual universities set up? The answers to all these questions and many more can be found out in this book. The technology which makes amazing feats possible is Virtual Reality. The awesome power of modern computer graphics and advances in haptics produce powerful virtual environments. So powerful are the environments that the users get fully immersed in it. The ...
A slew of cutting-edge technologies are shaping the future. One of the big impacts of technologies is about miniature-sized particles. These nano-particles are slated to change the world. A nano size is one billionth of a metre. At such a small size, properties of matter change considerably. This is partly due to increase in surface-area to volume ratio. Nanotechnology finds wide applications in areas as diverse as painting and coating, electronics, defense, ...
One does not think much about using mercury thermometers. If a member of the family falls sick, we quickly take out mercury thermometer and measure the temperature. Similarly, dental filling is a routine process for most of us. It never occurs to us that dental filling or thermometers can cause toxicity. But it is a fact. Breaking of mercury thermometer spills mercury beads that are difficult to collect. Dental amalgam contains mercury which may accumulate and ...
