Arithmetic, Population and Energy - 4 - a talk by Al Bartlett Part 4 of an engaging and informative talk by Al Bartlett. Professor Bartlett has given his celebrated one-hour lecture, "Arithmetic, Population and Energy: Sustainability 101" over 1,600 times to audiences with an average attendance of 80 in the United States and world-wide. His audiences have ranged from junior high school and college students to corporate executives and scientists, and to congressional staffs. Professor Al Bartlett begins his one-hour talk with the statement, "The greatest shortcoming of the human race is our inability to understand the exponential function." He then gives a basic introduction to the arithmetic of steady growth, including an explanation of the concept of doubling time. He explains the impact of unending steady growth on the population of Boulder, of Colorado, and of the world. He then examines the consequences steady growth in a finite environment and observes this growth as applied to fossil fuel consumption, the lifetimes of which are much shorter than the optimistic figures most often quoted. He proceeds to examine oddly reassuring statements from "experts", the media and political leaders - statements that are dramatically inconsistent with the facts. He discusses the widespread worship of economic growth and population growth in western society. Professor Bartlett explains "sustainability" in the context of the First Law of Sustainability: "You cannot sustain population growth and / or growth in the rates of consumption of resources." The talk brings the listener to understand and appreciate the implications of unending growth on a finite planet, and closes noting the crucial need for education topic.

Applications of Logarithms www.hrmvideo.com Applications of Logarithms uses dynamic images, computer graphics, and familiar language help to bring the mathematics of exponential and logarithmic functions to life. Students will come away with a clear mental picture of the behavior of these functions and of their many occurrences in the real world. Applications involve carbon dating on dinosaur fossils, nuclear decay, population models, interest and amortization, seismology, learning curves, and more. Transparencies and follow-up activities included in the kit allow students to further explore the concepts of exponential functions, common and natural logs, and the number.

Capacitive Touch Sensor: Learn Electronics with a Spooky Halloween Project Halloween is a great time to put your engineering prowess to work on a fun project. For this special Halloween project, we built a spooky candy bowl that lights up when an unsuspecting trick-or-treater reaches in. Using a microcontroller and some aluminum foil, we can build a capacitive proximity sensor that detects when a person's hand is nearby. For more details, explanations, and source code, please see: http://www.nerdkits.com/videos/halloween_capacitive_touch_sensor/ Tags: analog, atmega168, avr, capacitive, circuit, comparator, decay, dielectric, diy, electric, electronics, exponential, field, halloween, jack-o-lantern, jackolantern, learn, led, microcontroller, nerdkits, permittivity, project, proximity, pwm, rc, sensor, strength, timer, touch 1 Downloads - Last from: (Your Blog here!) |

The Most IMPORTANT Video You'll Ever See (part 1 of 8) 4 million views for an old codger giving a lecture about arithmetic?? What's going on? You'll just have to watch to see what's so damn amazing about what he (Albert Bartlett) has to say. I introduce this video to my students as "Perhaps the most boring video you'll ever see, and definitely the most important." But then again, after watching it most said that if you followed along with what the presenter (a professor emeritus of Physics at Univ of Colorado-Boulder) is saying, it's quite easy to pay attention, because it is so damn compelling. Entire playlist for the lecture: http://www.youtube.com/view_play_list?p=6A1FD147A45EF50D Tags: Albert, Bartlett, Julian, Malthus, Malthusian, Simon, arithmetic, capacity, carrying, change, climate, depression, economic, economy, energy, exponential, function, growth, oil, overpopulation, overshoot, peak, population, recovery, resource, steady, wars 1 Downloads - Last from: (Your Blog here!) |
