Information Storms and the Limits to Information
By Mary Logan
My first significant memory of big storms came as a 5 year old, as Hurricane Carla advanced on Port Aransas, Texas, where my father, HT Odum was administrator of the University of Texas Marine Science Institute. That day, as we were due to evacuate, HT took me on his final rounds of the Institute before leaving. We walked out on the Port Aransas pier, and I remember that my father had to lift me over the gaps where missing planks had already disappeared from storm waves (my mother was later horrified at my proud retelling of the story). We stood there halfway out on the pier, and I received my first lesson in hurricane science and energy transport in waves. We counted wave troughs, heights, and wavelengths, and he explained the dynamics of wind energy, relating the sizes of the pulses to size and scale of storms. Local weather creates little wavelets, and large distant weather creates bigger, more powerful pulses that have higher impact on beaches. We talked about excess heat in the atmosphere, and how hurricanes act as Nature’s way of dispersing extra heat. It was my first lesson in storm/energy analogies, and I have never looked at storms the same way since.
Odum often drew an analogy between the way meteorological storms such as hurricanes disperse heat and the way that other systems do, including information systems. After Tom Abel’s excellent post last week on trends in education in a world in transition, it is a good time to share Odum’s analogy linking storms of information and weather storms. But to make that analogy, we first need a meteorology lesson, starting with the second law of thermodynamics. Continue reading Information Storms and the Limits to Information
