In 1979 I took my first physics class in high school. I had always been pretty good in science and math, but physics was the perfect marriage of both. It explained everything in my mind. Sure, I had a basic understanding gravity, friction, drag, etc., but physics allowed you to precisely measure and calculate those fundamental properties.So, here we are over 30 years later. My son joined Cub Scouts as a Tiger Cub and we were exposed to one of the biggest annual physics experiments in the world.... The Pinewood Derby.Over the next four years, my son and daughter experienced a lot of success in the Pinewood Derby at both the pack and district level. In my son's final year of competition, he won the den, pack, and district races as well as a race that was held at the National Scouting Museum in Irving, Texas. I thought that was it for the Pinewood Derby, but I was wrong....At my kid's elementary school, fifth grade is the year that they all participate in the science fair. My wife and I were dreading the upcoming projects since we have twins. Then one day at work, a fellow engineer told me about how he and his son did a physics based science fair project. Bang! The light went on in my head and I thought, "Wow, why don't we do a project based on the physics of the Pinewood Derby." I pitched the idea to my kids and they were both all in.The problem with the science fair project was to figure out what we were trying to prove. We pretty much already knew how to build a winning car, so all we could really do is show how to make the car slower. So, that's what we did. We built a control/test car that applied all the best practices that we had learned along the road. Then we changed the mass, center of gravity, friction and drag to show how each of these attributes effected the performance of the car.My kids worked really hard on this project and by the end, really had a grasp of why the cars they had helped to build every year were so successful. It wasn't just luck, it was physics. The project came out great. I mean really great. They won their school's science fair and placed 2nd in the city wide district science fair. Personally, I would take those two victories over all the Pinewood Derby victories combined.As the project came to a conclusion, I came to a realization. There is a lot of info on the web about how to build a winning car. What you can't find is experimental data that quantifies the effect of not following the winning recipes. In other words, what is the sacrifice if you don't follow all the known speed secrets.This booklet attempts to quantify the sacrifices you can expect if you don't optimize the weight, center of gravity, drag and friction. The data my kids collected for their elementary science fair experiment will show you just how important each of these attributes are and what you can expect if you decide to cut corners.I also picked up a couple of speed secrets along the way. I will provide you with what I think are some really good tips on lubrication, polishing of axles and wheels, drag and friction reduction, weight placement and adjustment. In particular, the approach we used to polish and lubricate the axles and wheels is superior in my opinion.What I really hope is that this book helps you figure out quickly how to build a car that is very competitive without wasting a bunch of time on the web. Enjoy, and happy racing!
Provides a brief history of the Boy Scouts' Pinewood Derby as well as diagrams, templates, and tips to help parents and children gain a competitive edge in a Pinewood Derby race.
There is no secret to creating a winning Pinewood Derby car; all racers need is a great design and an understanding of these tips that trick their cars out for maximum speed. In three sections, this handbook takes builders from the beginning of car construction to ultimate derby-winning modifications. The "basic car" section addresses broad building concerns such as cutting the design, attaching and lubricating the wheels, and balancing the weight. "Winning car" secrets include extending the vehicle base, polishing axles, and modifying and aligning the wheels. Finally, the championship techniques of the "ultimate car" are revealed, allowing builders to shave those last tenths of a second off their times and go home with the trophy.
The excitement of competition! A detailed, inspirational booklet that explains the specifics of building your pinewood car for speed. Make your car the fastest it can be with secrets that will give you a winning edge! We speak out of the experience of four years of consistent wins. Useful for the Cub Scouts or Boy Scouts Pine Car Derby Royal Rangers, Royal Ambassadors, Awana Grand Prix, Shape N Race, Kub Kar Rally and other groups.
NEW YORK TIMES BESTSELLER • NASA astronaut Mike Massimino shares incredible true stories from space—a rare, wonderful world where science meets the most thrilling adventure. “Mike is a spaceman through and through; he tells how hard work can take you out of this world.”—Bill Nye the Science Guy Have you ever wondered what it would be like to find yourself strapped to a giant rocket that’s about to go from zero to 17,500 miles per hour? Or to look back on Earth from outer space and see the surprisingly precise line between day and night? Or to stand in front of the Hubble Space Telescope, wondering if the emergency repair you’re about to make will inadvertently ruin humankind’s chance to unlock the universe’s secrets? Mike Massimino has been there, and in Spaceman he puts you inside the suit, with all the zip and buoyancy of life in microgravity. Massimino’s childhood space dreams were born the day Neil Armstrong set foot on the moon. Growing up in a working-class Long Island family, he catapulted himself to Columbia and then MIT, only to flunk his first doctoral exam and be rejected three times by NASA before making it through the final round of astronaut selection. Taking us through the surreal wonder and beauty of his first spacewalk, the tragedy of losing friends in the Columbia shuttle accident, and the development of his enduring love for the Hubble Telescope—which he and his fellow astronauts were tasked with saving on his final mission—Massimino has written an ode to never giving up, revealing just what having “the right stuff” really means.
Provides ideas, tips, and patterns for making a sharp-looking, fast car to race in the Cub Scouts' Pinewood Derby.

Winner of the International Lannan Literary Award for Nonfiction Animal tracks, word magic, the speech of stones, the power of letters, and the taste of the wind all figure prominently in this intellectual tour de force that returns us to our senses and to the sensuous terrain that sustains us. This major work of ecological philosophy startles the senses out of habitual ways of perception. For a thousand generations, human beings viewed themselves as part of the wider community of nature, and they carried on active relationships not only with other people with other animals, plants, and natural objects (including mountains, rivers, winds, and weather patters) that we have only lately come to think of as "inanimate." How, then, did humans come to sever their ancient reciprocity with the natural world? What will it take for us to recover a sustaining relation with the breathing earth? In The Spell of the Sensuous David Abram draws on sources as diverse as the philosophy of Merleau-Ponty, Balinese shamanism, Apache storytelling, and his own experience as an accomplished sleight-of-hand of magician to reveal the subtle dependence of human cognition on the natural environment. He explores the character of perception and excavates the sensual foundations of language, which--even at its most abstract--echoes the calls and cries of the earth. On every page of this lyrical work, Abram weaves his arguments with a passion, a precision, and an intellectual daring that recall such writers as Loren Eisleley, Annie Dillard, and Barry Lopez.
