“The Revolutionary War” provides a detailed overview of the American battle for independence and the forging of a nation. From the earliest skirmishes at Lexington and Concord to the decisive victory at Yorktown, to the writing of the Constitution and the struggles of early national America, this book tracks both the logistical and intellectual dimensions of the "revolution," which, as John Adams said, took place "in the hearts and minds of Americans . . . before a single drop of blood was shed." As much as it vividly documents the particulars of battle, it is the dizzying aftermath of the war and the complexities of fulfilling the "idea" of America that form the impressive substance of this book. Also discussed are the social, cultural, and artistic advances of the post-Revolutionary period, including women's suffrage and the beginning of public education, with special emphasis given to the "American Renaissance" and the rising of distinctly American literature.

Hoot By CARL HIAASEN.

Unfortunately, Roy’s first acquaintance in Florida is Dana Matherson, a well-known bully. Then again, if Dana hadn’t been sinking his thumbs into Roy’s temples and mashing his face against the school-bus window, Roy might never have spotted the running boy. And the running boy is intriguing: he was running away from the school bus, carried no books, and–here’s the odd part–wore no shoes. Sensing a mystery, Roy sets himself on the boy’s trail. The chase introduces him to potty-trained alligators, a fake-fart champion, some burrowing owls, a renegade eco-avenger, and several extremely poisonous snakes with unnaturally sparkling tails. Roy has most definitely arrived in Carl Hiaasen’s Florida.

The Tower Windmill from Ugears is more than a mechanical puzzle. It is an exciting adventure into the history of old England. The model is based on the Chesterton Windmill, a 17th-century cylindrical stone tower windmill that was built outside the village of Chesterton, Warwickshire county. Built around 1632-33, the Windmill was restored between 1965 and 1974 and today it is the earliest tower mill in England to retain any of its working parts.

This unique construction with an arched base was presumably built by a prominent figure of the period, Sir Edward Peyto that owned Chesterton Manor at that time.

Sir Edward was an enthusiastic mathematician and astrologer, which brought up the presumption that the tower mill was initially designed to become an observatory. Although there is no evidence to support this theory and we can only guess what had driven the post-medieval nobleman to create this beautiful and unique windmill.

This Ugears model designed in “Victorian steam-punk skeleton” style is based on a prototype from Chesterton.

When spinning rapidly the aerodynamic twist sails create fairly strong wind. It also can work the other way around: blowing air directed at the sails will make them spin. Use a fan to demonstrate to your kids how real windmills operate.

A double planetary gear reducer with differently shaped gears provides the necessary speed.

The model is powered by a removable rubber band motor. Once the motor is removed, the Windmill can work in a manual mode that allows you to observe and examine the fascinating complex mechanism in detail.

The rubber band motor drives the sails by means of a screw conveyor (worm feeder) and gear transmission. The design of the gear transmission includes a flexure link, the type of chain drive assembled out of many small links. The full-fledged chain drive made out of plywood has never been used in the Ugears models before.

Resembling a spiral staircase, the rotating base of the arched tower is a part of the screw conveyor mechanism that is a chief part of the model’s mechanism. Fascinating mechanics of the moving gears will captivate your attention for a long time.

While taking origin from the English prototype, the Ugears model also addresses the Spanish classic: the Tower Windmill comes with the figures of the Ingenious Nobleman Don Quixote and his quirky companion Sancho Panza.

The Ugears Tower Windmill model kit is made of sustainably sourced high grade wood and has everything you might need for assembly. The quality of the parts is top-notch: a laser method is used for cutting items from a plywood board that provides precise hairline cuts. The details have to be pulled out of the boards and assembled to create a complete model. Like all other Ugears models, the Tower Windmill comes with step-by-step, full-color, truly easy to follow instructions in 11 languages (English, German, Ukrainian, French, Polish, Spanish, Russian, Turkish, Italian, Chinese and Korean) and requires neither glue nor special tools to be fully assembled into functional working Windmill.

Assemble it and discover the principle of working of the Three-digit Clicker-Counter

• Experiment: the model comes with a Pocket Model’s Study Guide with a creation story and mechanism design as well as engaging and interesting tasks.
• Immerse yourself in Augmented Reality (AR), find out how the Counter is used in a production line, and interact with it via the dedicated Ugears application.

Learn how the COUNTER works

The Counter is a stylised educational model, an interactive study guide to the mechanism, only for learning its essentials and principles of working. It registers repetitive actions. It is an integral part of a device called an “Odometer”. The model has three cylinder gears with numbers from 0 to 9 and a Geneva Drive. This combination allows you to see an interesting mechanical feature: when the reciprocating motion of the click-button using the Geneva Drive mechanism turns into the rotary motion of the cylinder gears with numbers. The Counter provides two options of data registering: click-button on the roof of its body, and a turn handle on its side. Pressing the click-button or turning the handle makes the Counter shift by one place. When the count passes 9, the Geneva Drive catches the next register cylinder and adds it to the count. Altogether, the three-digit display of the Counter can register values from 1 to 999. You can open the front panel of the counter and reset it manually. Try counting steps on your way home. Or how many people you meet on a stroll through the park. How about, the number of blue cars passing by your house during one hour? Count stairs at home, at school, or at a friend’s house.

When and who invented it

A counter, as a key part of the odometer mechanism, was invented by an Ancient Greek mathematician and engineer Hero of Alexandria who lived in 10-70 AD. It measured the length of the path by counting the number of rotations of the wheel. Later, the counter was improved and completed with a reducer that reduced the number of the wheel's revolutions depending on the measuring system (miles, leagues, kilometers) and showed reduced data on the display.

Usage

These days, counters are used to count the number of passengers, visitors of different events, cars passing through certain check point, sets and scores in sport, items on a production line, etc

Number of components: 157

Estimated time of assembly: 1-2 hour
