Since the earliest times mankind has employed the simple geometric forms of straight line and circle. Originally marked out by eye and later using a stretched cord, in time these came to be made with the simple tools of ruler and compass. This small book introduces the origins and basic principles of geometric constructions using ruler and compass, before going on to cover dozens of geometric constructions, from the practical fundamentals to the more demanding.

- Constructions for more than thirty regular polygons

 

- Introduces geometric construction using compasses alone and using rulers alone

 

- Explains why trisecting an angle is impossible using classical rules and how to trisect an angle anyway

 

- Highlights the relationship of geometric construction with many fundamental developments throughout the history of mathematics

 

Wooden Books was founded in 1999 by designer John Martineau near Hay-on-Wye. The aim was to produce a beautiful series of recycled books based on the classical philosophies, arts and sciences. Using the Beatrix Potter formula of text facing picture pages, and old-styles fonts, along with hand-drawn illustrations and 19th century engravings, the books are designed not to date. Small but stuffed with information. Eco friendly and educational. Big ideas in a tiny space. There are over 1,000,000 Wooden Books now in print worldwide and growing.

Almost not edible
Flavor Name: Traditional, Size: 2 Ounce (Pack of 3), Flavor Name: Traditional, Size: 2 Ounce (Pack of 3)
I am south african, an afrikaaner. I grew up eating droewors and biltong. I'm not sure what went wrong with this product. I have to believe it was off quality product and not what they are choosing to ship. The flavor was ok. Nothing spectacular. Thr big issue was texture of the droewors and the fact that the meat had shrunk away from the casing leaving the casing inedible. See my pic. This is not what droeworse looks like. Also, being from south africa I've never heard anyone say the word ayoba....

Good taste. A bit dry texture.

Great taste. Unusual flavor but still good. It was a very dry texture. I do want to try another flavor.

Meh
Flavor Name: Traditional, Size: 2 Ounce (Pack of 3)
It’s just okay. I’ve been looking for something that is as close to possible as dry wors in South Africa. This is not it. Is it dry wors? Yes. But is it good dry wors? No; it is very average. I wouldn’t buy it again. I’ll have to keep on searching for that yummy, moist, soft, flavorful dry wors that seems so elusive on this side of the pond.

Droewors + WHY BARS
Flavor Name: Traditional, Size: 1 Ounce (Pack of 12)
I like them as they are a quick snack on the go. I go for these beef sticks and I eat lots of tasty WHY BARS to get high-quality nutrition for my busy lifestyle. Why not!
