As an engineering major, I agree that this is cooler than magic

This so cool, thanks so much for sharing; Jess Christ Bless you! :)

Thank you very much,,, \i am attempting to add a spiral design to my art work... i am so happy i found your tutorial. Thank you for sharing..
-
Thank you for your video sir. I'm a new artist with an interest in fractals and complex geometry.
-
That was actually pretty cool. Thanks :)
-
I love this demonstration, it is very very helpful... Thanx a lot

Hi. great tutorials. I was looking for an archimedian spiral to complement my drafting of spiral phyllotaxis. I just have one ruler and compass related question. At 1:05 of this tutorial you use the "division of a line" technique. Can you elaborate as to how you do that?
-
nice one !!!!!! liked it...........
-
Great to watch... learnt things.
-
That style of compass is unique. I never seen one before. Is that a special lead pencil that comes with it ? Thx
-
Thank you for showing this method, it was a process I found a little confusing until I viewed your demonstration so thank you again.

Excellent tut. Is this the same as a Fibonacci spiral? I made a spiral drawing compass,based on that.|It has a piece of silver chain attached to a Fibonacci spiral.You can place the pencil in any of the holes in the chain,and it will draw a nice spiral of different sizes. I'm learning hand engraving,and that is the basis of nice looking scroll-work.

You know what's cooler than magic? MATH!

Need this curve to add trim to a Wainscott chair. Many thanks sir.
-
Can you link that fabercastle thing which you used to draw parallel lines?
-
Just another way of approximating a spiral using various radii. A true spiral, like a true ellipse, contains no radial lines. Of course architects, artists and builders need.practical means of drawing and designing stuff. A true spiral may be produced by a pencil attached to a string, unwrapping around a spool (a near useless bit of knowledge, I know.)

This is awesome, great explaination

@7pyroman7 simply put the archimedean spiral is the locus of a point as it moves from A to B while rotating through 360 degrees. The equation of the spiral of Archimedes is r = aθ. the spiral winds around a point while moving ever farther from the point. Many kinds of spirals are known, the first dating from the days of ancient Greece. The curves are observed in nature, and human beings have used them in machines and in ornament, notably architectural—for example, the whorl in an Ionic capital.

nice and clear, this helps me a lot, I got general idea, thanks!)
