Comment There is a link but it is not all roses (Score 4, Insightful) 402

I am by no means special as there are likely hundreds of thousands like me. I started out young, labeled as "gifted", and put through special school programs. I have a very high IQ, and have the ability to create extremely intricate CAD-like images of any thing I can dream up, transpose and create into real working hardware. I learn new languages and programming languages with virtually no effort, and I am amazed at my own abilities sometimes. Other times ashamed. The price has been trips to the mental hospital with a severe bi-polar diagnoses and extreme depression, where I cannot even function as a normal human being some days. I love who I am and wouldn't want to be anyone else, but I understand that my brain is all on or all off, and that is the gift and the curse.

NOPE. Some excerpts from YOUR link... "One might expect that the origins of the sign would also be known for certain particularly when the origin of the British pound sign, £, which is far older, is well-established. However that is not the case with regard to the dollar." "There is another version of the theory linking the sign to the Spanish peso. As mentioned earlier the peso was subdivided into eight reals, hence the name piece of eight.The 8 with two strokes became a letter S with two strokes since S looks like an 8 that has been split, as when a peso was broken to provide change in reals. Eventually a further simplification was introduced by dropping one of the strokes." Read YFA.

Comment Leave the icons alone (Score 5, Insightful) 713

The dollar sign is thought to be a slash through an eight representing 'pieces of eight', an older Spanish currency denomination, but everyone still knows what $ means. Icons that everyone is used to and that can be recognized as to their function should be left alone, for efficiency and a nice little piece of nostalgia.

Comment Ion engines are already pretty efficient... (Score 3, Informative) 100

and that is not the big issue, as getting off the ground is always the big expense, but we all know that. This tech can be useful in reducing weight costs for sub orbital payloads though, and probably resembles the design of a DS4G engine. The problem with efficiency in the past is that motors required high voltages to accelerate the ions that collided with the electric field grids. DS4G used a two stage four line grid with the top grid closely spaced and of higher voltage, with an open spaced lower voltage bottom grid. These differences between these stages allow higher velocity without ion grid collision at overall lower voltages resulting in 4x the fuel efficiency of previous engines.
