Pi is a lie. Happy Half Tau Day

Pi is a lie. The concept of Pi (π) is confusing and makes trigonometry more complex than it needs to be. Math can be made easy to learn and understand. Michael Hartl proposes that we reclaim that simplicity through the use of Tau (τ).

Enjoy this video made by a Math student who understands the logic of Tau and the need to increase its popular use.

Intrigued? Try tasting this bit of Tau (excerpt from "The Tau Manifesto"):
The Tau Manifesto is dedicated to the proposition that the proper response to “π is wrong” is “No, really.” And the true circle constant deserves a proper name. As you may have guessed by now, The Tau Manifesto proposes that this name should be the Greek letter τ (tau):
τ ≡ C/r = 6.283185307179586…
Throughout the rest of this manifesto, we will see that the number τ is the correct choice, and we will show through usage (Section 2 and Section 3) and by direct argumentation (Section 4) that the letter τ is a natural choice as well.

Happy Half Tau Day! The complete celebration will come on the 28th of June.

Why I hate Daylight Saving Time

In a matter of hours clocks across the United States of America will be "wrong" by an hour due to the onset of Daylight "Saving" Time1.

The advantages and disadvantages of Daylight Saving Time have been debated at length for nearly one hundred years. We've all heard the legend of the great inventor and founding father Benjamin Franklin decreeing DST to benefit agriculture across America. (Really, I think he just didn't like the night life in Paris and thought he'd go about suggesting a shift in behavior by having them "use more daylight". ["Benjamin Franklin: America's Inventor" - HistoryNet])

Daylight Saving Time didn't come into recognizable use until the first World War. During which much of the world's energy was spent on lighting (with fuel which could be put to better use in the war). A fact which really can't be used with current arguments for DST. Lighting is a small fraction of our modern day energy usage; instead, heating and cooling systems make up the biggest portion. Resulting in the following scenario today:
With DST, people return with an extra hour of sunlight. An hour during which homes would have cooled further. Once individuals enter a warmer house, they crank some cold air out of the cooling systems.
So, much for energy savings. You see, they didn't have electricity sucking HVAC systems back when they started this DST thing. Don't worry, though, some would have you push your evening plans out an additional hour if you were so concerned about coming back to a warmer house. (The same hour DST took away.)

Ignoring the involvement of energy companies, there are many industries which claim a benefit from DST. Tourism, sports, and retail; to name a few. Customers of these industries consume more of their products and services during the daylight; if they can catch a few more customers after the workday is through then that's money in the bank. That's not a bad thing for those industries to want, so I don't fault the efforts to take advantage of the time change. It does mask the larger issue, which started DST in the first place.

The idea of Daylight Saving Time is to make the most of the hours of daylight available during the Summer. That's fantastic! Unfortunately, people use DST as a crutch to hobble a few days of good feelings out of "more" daylight. You've heard this before, but I'll say it again: If you want more daylight, then use it when it's there. Consistently. I'm definitely not going to do what Ben Franklin did and tell you how to spend your day though; in fact, I'd rather point out a consequence encountered when using DST.

Tomorrow morning, you are going to feel like crap. You're going to wake up, look at your clock and think, "What?! It's ??:??. How is it so late?!" That feeling of panic is not only because of DST (just as little as that feeling of rest in the Spring); it's because you got an hour less of sleep. If you don't like that feeling, then you should consistently try to get an extra hour of sleep. DST "takes" away an hour of night for most people; moving that darkness from the evening to the next morning. Personally, I think it's your choice to define your sleeping habits as you want. Additionally, I don't think there should be any attempt to dictate whether you choose to play during the day or night. In 1779, however, Ol' Ben thought he knew best and suggested Paris "early to bed and early to rise", but we both know that sometimes more excitement can be found after dark or in sleep.


1 Technically, my clocks are all either radio clocks [wikipedia] or using NTP [wikipedia] and, therefore, set the time automatically according to either the radio signal being broadcast by WWVB [wikipedia] here in Fort Collins, Colorado or the NTP server wwv.nist.gov hosted by the same.

Thumb-cat Apocalypse

In a creative and memorable advertisement for its Cravendale milk, Arla Foods UK humorously presents a very simple question: "What would happen if cats had thumbs?"

If they develop the use of thumbs, the whole of human civilization will fall before the kingdom of the kitty. Be afraid. Be very afraid.

INDY Adventure Map updates

Over the weekend I made some adjustments to the map appearing on the main page of the Adventure section (http://www.indy.cc/adventure/). In addition, I updated the location which allows INDY members to indicate the places they've visited around the world. (Members can now mark places they've visited, even if those places no longer exist on a map. e.g. the USSR, Yugoslavia, etc.)

The map, viewable to all, is an implementation of a Flash product created by Antanas (www.ammap.com). This weekend I created a new world map for the Adventure section which uses a Fuller projection [wikipedia: Dymaxion Map] to display the continents with nearly accurate surface areas.


I think the Fuller projection is a much nicer 2D presentation of our planet as there is little distortion -- such as the distortion which makes Greenland look larger than Africa on many maps. Additionally, the viewer is able to see all of the continents laid out on a single plain (including Antarctica).

INDY Nostalgia

I've become nostalgic about the site design of INDY.CC before the 2007 redesign. In remembrance of the original layout, over the course of the next 10 days I will be adjusting the site's appearance. The commutation of this effort will come on February 21st, six and a half years after INDY.CC was revealed in 2004 on August 21st.

INDY Poll: What do you fear?

On Wednesday, you read how to begin overcoming your fear(s) in the "Groundhog Day 2011" post. Along that same line, this INDY Poll asks, "What do you fear?"

List items inspired by "10 Common Phobias" - About.com

I'm trying out a new method of handling the INDY Polls by using BlogPolls.com. Hopefully, this will allow me to automate and simplify the release of the polls and better manage the results.

Groundhog Day 2011

It's hard to agree that Spring has arrived when the temperature is currently -20°C (4°F) in my town of Fort Collins, Colorado, but today both fact and tradition say it is so. Punxsutawney Phil did not see his shadow today which confirms the fact that today is a cross-quarter day1 and therefore the start of Spring.

This year, I encourage you to shed the burden of your fears and journey forward toward your goals in the adventure of Life. We often weigh ourselves down with trepidation about the decisions we make. Today, challenge the root of those fears, whether they are minor doubts or massive phobias.

Don't expect yourself to overcome fear with one thought or intention; recognize the challenge that you must face every time you feel the angst set in. Slowly, every time you "face your demon", the fear will dissipate.

Now, let me offer you some tools with which to defy your misgivings:
- Introspection: Identify the root fear(s). The root fear is the one on which you should focus your attention.
Is it truly a fear of heights (vertigo) or the fear of falling? What, specifically, does and doesn't scare you about spiders? What causes the nervousness you feel in front of "crowds"?

- Acceptance: Once you identify the root fear, teach yourself to accept and acknowledge that you currently have this fear. Do not give power to the fear by pretending it doesn't exist. We all have fears, true strength will come from owning yours.

- Understanding: Delve into the root fear. During (or after) an experience causing fear, feel the symptoms of the fear on your mind. Understand what happens to you when your fear takes hold. (e.g. tightness of the chest, dizziness, weak knees, sweaty palms, blurred vision, etc.)

- Treat the symptoms: Begin by counter-acting the symptoms. For example: take a deep breath when you feel your chest tighten (recognize you can breathe); steady yourself on a stationary object (get your balance); bend your knees slightly and straighten your spine (acknowledge your posture); dry your hands with a cloth or chalk; close your eyes briefly and think of the next object you will look at.

- Knowledge: Learn all you can about your fear; study the facts, determine the reality. Knowing the truth will completely eliminate in fears based on false or misunderstood concerns.

- Anticipate: Take steps to prevent any cause of the root fear; "safety first". For example, if you fear falling, secure your footing, grip, or attach yourself to safety rigging (harness, ropes, etc.). Double check your prevention, to put your mind at ease; show yourself that "it works".

- Trust: Have faith in the steps you have taken to protect yourself from your fear. (Self-doubt is sometimes attributed to "[c]hildhood experiences, these traditions maintain, [and] can plant doubt about one's abilities and even about one's very identity." ["Doubt" - Wikipedia].)

- Engage: Actively address your fear when you experience it. Using all that you have learned and the precautions you have taken, directly challenge your fear. Mentally process and counter any thoughts with the facts you have learned. Treat any symptoms and assure yourself of your safety.
It is natural to feel fear, but some fears are unnatural. Set your goals, challenge your world-view, but respect your limits.

Bill Maher: Founding Fathers vs. Tea Party

Bill Maher recently poked some holes in the Tea Party's attempts to tie themselves to the Founding Fathers of the United States of America. Take a look at this humorous clip from Maher's show Real Time:

Source URL: http://tpmdc.talkingpointsmemo.com/2011/01/bill-maher-to-tea-partiers-the-founding-fathers-would-have-hated-your-guts-video.php

I found the Thomas Paine / Glenn Beck comparison the most entertaining. To be honest, Bill Maher humorously illustrates a very disturbing fact about the individuals who subscribe to the Tea Party rhetoric (whether officially or through complaisance); they appear to lack the initiative, resources, and/or education to be properly informed about the history, implications, and outcomes of their misconceptions and resulting actions.

I hold out hope that the natural curiosity inherent in human nature, coupled with our immense treasury of knowledge, will enrich our educational system for the betterment of our species.
