## Random Electroform Art – How It Can Be Created

[caption id="attachment_14086" align="alignright" width="480"] Gold-plated dendritic copper electroform art.[/caption] Art takes many forms. As a chemist, I was assigned the task of forming high frequency electrical devices. I "grew" them from water based solutions of copper salts. I then electroplated them in gold baths. I'd found my kind of art - random electroform art! No one can say it is unoriginal. Preparation A form, or mandrel, was made of machined aluminum. A sodium zincate dip and rinse followed. Copper was grown over that. Not all areas received growth, though. Forms were masked to prevent growth in certain spots with a vinyl coating. This was applied by dipping and "painting." Growth After drying, the mandrel was inserted into the bath. Electricity was applied. Copper deposition began. After growth completion, the piece…

## Geometry Stop the World – I Want to Get Off

[caption id="attachment_3951" align="alignright" width="440"] Space Time Curvature - GNU Free Documentation License Version 1.2 by Johnstone[/caption] Many of us had to take plane geometry in high school. If you remember it was, “Theorem, Proof, Theorem, Proof...” What kind of ammunition did you use for the proof of a theorem? The axioms and previously proven theorems. I know, I know. Some of you want to forget the anguish. But I want you to recall the fifth axiom... Plane Geometry - Diagram 1 Look at Diagram 1. directly below. Line a is parallel to line b. That is lines a and b don’t meet. Axiom V: Through the point where line t meets line a there is no other line that can be drawn parallel to b. Now it took about 2,000…
