Exponential thinking promotes a systems approach, encouraging us to look at problems holistically and to seek solutions that have a far-reaching, transformative impact. The Data Revolution.

Radiation mapping using a double exponential attenuation model for UAV sensing in forest area Abstract: Changing amount of radiation dose has been a great concern by citizen near the ...

Applying theoretical derivation, it concludes that the photon’s energy, momentum, and frequency decrease with distance in an exponential attenuation law, or the wavelength increases with distance in ...

An "exponential gap" is opening up between our understanding of our world, which updates slowly, and new technologies, which change faster than we can cope with, argues Azeem Azhar.
