Philographics on the Behance Network. An Intuitive Guide To Exponential Functions & e. E has always bothered me — not the letter, but the mathematical constant.

What does it really mean? The mathematical constant e is the base of the natural logarithm. And when you look up natural logarithm you get: The natural logarithm, formerly known as the hyperbolic logarithm, is the logarithm to the base e, where e is an irrational constant approximately equal to 2.718281828459. Nice circular reference there. I’m not picking on Wikipedia — many math explanations are dry and formal in their quest for rigor. No more! E is NOT Just a Number Describing e as “a constant approximately 2.71828…” is like calling pi “an irrational number, approximately equal to 3.1415…”. Pi is the ratio between circumference and diameter shared by all circles. E shows up whenever systems grow exponentially and continuously: population, radioactive decay, interest calculations, and more. Understanding Exponential Growth Let start by looking at a basic system that doubles after an amount of time. A Closer Look.

Introduction - 10,000 Year Clock. The full scale 10,000 Year Clock is now under construction.

While there is no completion date scheduled, we do plan to open it to the public once it is ready. The essay below by Long Now board member Kevin Kelly discusses what we hope the Clock will be once complete. This is one of several projects by Long Now to creatively foster long-term thinking in the context of the next 10,000 years. by Kevin Kelly There is a Clock ringing deep inside a mountain. Is around to hear it.

The Clock is real. The Clock is now being machined and assembled in California and Seattle. The Clock’s inventor introduced the idea of the Clock (in 01995) with this context: I cannot imagine the future, but I care about it. Lectures. Lectures.

Fallacy List. 1.

FAULTY CAUSE: (post hoc ergo propter hoc) mistakes correlation or association for causation, by assuming that because one thing follows another it was caused by the other. example: A black cat crossed Babbs' path yesterday and, sure enough, she was involved in an automobile accident later that same afternoon. example: The introduction of sex education courses at the high school level has resulted in increased promiscuity among teens. A recent study revealed that the number of reported cases of STDs (sexually transmitted diseases) was significantly higher for high schools that offered courses in sex education than for high schools that did not. 2.

SWEEPING GENERALIZATION: (dicto simpliciter) assumes that what is true of the whole will also be true of the part, or that what is true in most instances will be true in all instances. example: Muffin must be rich or have rich parents, because she belongs to ZXQ, and ZXQ is the richest sorority on campus.
