Asks the reader to: assume there is incredible technological progress in endeavours to solve problems of energy scarcity, pollution and congestion; imagine a super Super Car powered by a pollution-free perpetual motion engine; imagine a super Internet which provides free and efficient access to all the databases and libraries in the world. The result would be a social and environmental disaster...

INTRODUCTION The new ADXRS150 and ADXRS300 gyros from Analog Devices, with full-scale ranges of 150/s and 300/s, represent a quantum jump in gyro technology. The first commercially available surface-micromachined angular rate sensors with integrated electronics, they are smaller—with lower power consumption, and better immunity to shock and vibration—than any gyros having comparable functiona...

Recent prescriptions for rescuing civilization from collapse involve extending our human capacity for empathy to a global scale. This is a worthy goal, but several indications leave grounds for cautious optimism at best. Evolutionary biology interprets non-kin helping behaviors as products of natural selection that rewarded only the transmission success of resident genes within ancestors, not t...

However, One of the most important s...

A representation changer is a function that converts a concrete representation of an abstract value into a different concrete representation of that value. Many useful functions can be recognised as representation changers; examples include compilers, and arithmetic functions such as addition and multiplication. Functions that can be specified as the right inverse of other functions are special...
