Hyperbolic geometry describes surfaces that are negatively curved .

Dad was set up in a nice corporate apartment , he loves to cook , and he 'd be flying home on the weekends , so my hyperbolic scenario wasn 't likely to become a reality .
Now , says prof series , hyperbolic geometry promises to advance our understanding of the way complex networks such as the internet behave and grow .
希尔丽丝教授表示，如今，双曲几何将有望提升我们对互联网等复杂网络表现和增长方式的理解。
In other words hyperbolic discounters are able to make the rational choice when they 're thinking about the future but as the present gets closer short-term considerations overwhelm their long-term goals .
Most of the contributors to the new book agree that this peculiar irrationality stems from our relationship to time-in particular from a tendency that economists call " hyperbolic discounting . "
