    Geometry Tools
AI Thread Summary
When selecting tools for learning geometry, a compass, protractor, and ruler are essential, but high precision is not necessary unless pursuing a career in drafting. Basic tools can be effective, and inexpensive options like clear plastic rulers from supermarkets are recommended. Keuffel & Esser compasses and drafting sets are praised for their superior quality compared to modern alternatives, often available on eBay at reasonable prices. Concerns about rust on older tools can be addressed with proper cleaning methods. The Alvin compass is mentioned as a potential option, though its quality may not match that of vintage K&E tools. Overall, the discussion emphasizes the value of well-engineered tools for a tactile learning experience in geometry, while also noting the decline in the market for high-quality drafting tools due to the rise of computer-aided design.

What are great compass, protractor and ruler brands for geometry? I want to learn geometry properly and I need to invest in some tools. Price is not an issue if the tools will last many years

Oh well, they would be my tools right here and I'll sell them to you for an easy million :D

You don't need high precision tools unless you want to become a draftsman - and these days they use computers.

To learn geometry, you just need a compass and a straight edge - and they don't need to be fancy.
You can even make them yourself.

The cheap clear plastic rulers you get in a supermarket are excellent.
They probably sell several types of compass too.
 
You can find very nice Keuffel & Esser compass and drafting sets on eBay for no more than you'd spend to buy a new set of Alvin drafting tools and the quality of the K&E items is generally superior to the modern items. There's nothing like the tactile feedback of using a well engineered compass while exploring geometric constructions.

Little worried about the rust on these lol. If they show rust how do I get them into pristine condition?

I was looking at the Alvin compass. Anyngood.? It's the one listed for 25 dollars on amazon.

What are quality rulers? 45 triangles and protractors?
 
I have bought a set for $18 that had no rust at all. I also have an Alvin set and the workmanship and materials are not in the same league as the K&E sets from yester-year. As for other tools you can find them on eBay as well. Since the dominance of computer drafting the market for quality drafting tools has dried up and it is somewhat a curiosity to acquire old tools.
 

Thread '"WHAT IS A QUANTUM FIELD THEORY?" A First Introduction for Mathematicians'

The book is fascinating. If your education includes a typical math degree curriculum, with Lebesgue integration, functional analysis, etc, it teaches QFT with only a passing acquaintance of ordinary QM you would get at HS. However, I would read Lenny Susskind's book on QM first. Purchased a copy straight away, but it will not arrive until the end of December; however, Scribd has a PDF I am now studying. The first part introduces distribution theory (and other related concepts), which...

Thread 'Books with a more theoretical approach to turbulence and DNS'

I've gone through the Standard turbulence textbooks such as Pope's Turbulent Flows and Wilcox' Turbulent modelling for CFD which mostly Covers RANS and the closure models. I want to jump more into DNS but most of the work i've been able to come across is too "practical" and not much explanation of the theory behind it. I wonder if there is a book that takes a theoretical approach to Turbulence starting from the full Navier Stokes Equations and developing from there, instead of jumping from...
