The most important invention in history given a coin

You seriously did math equations with a PEN? Was it one of those erasable pens, or are you a super genius, or just like to rewrite homework papers over and over again?

I could never do a sheet of calc equations without one or two needing serious fixing personally.

Yes always a pen, like most people. WHo can be bothered shapening a pencil with calculations that span 5 pages?

 

And yes, I am generally considered a super guinous Except i can not spell.

 

And apparently you can't post more than one idea in a single post either.

 

Right, because I don't want to confuse the simple people.

 

BTW - I was going to say that I'm enjoying the list of what people think are important inventions. Not all of these are on coins.

And that way maybe by summer's end you can catch up to Doug's 32,000 posts (or whatever he has nowadays).

 

If I wanted to. It's not that hard if that is a goal. Is that your goal or are you just being pardisulous?

Nice comeback Ruben!

 

well, if anyone doubts my abilty to write long and drawn out arguments and discussions, all they need to do is do a search on the sight and look. As soon as someone writes something worth responding to with more than a few lines, then I'll be happy, despite the pain in my hands and wrist, to write such a response.

feh - there is always a complaint and a comment, and far and away not enough tolerance. One thing about living in New York, you learn to tolerate people because you can't spend your life fighting with them all and insulting them. In fact, that would be a good way to get yourself beaten in the city.

I'm starting to think maybe the "ignore" button is the greatest invention ever.

 

it doesn't bother me. Its your loss. The only thing that ever bother me was the guy who refused to put me in his ignore box, but after I ignored him, he insisted on sending nastygrams though the private communication.

 

how did you join 3 years after I did?

 

I was lazy!

 

Show me a coin with a slide ruler then..

 

I haven't a clue of what you are talking about. How does a coin with a slide ruler have anything to do with what I posted?

 

Well, I just thought that if a slide ruler was such a great invention there should be acoin with it


to answer your question, i naturally used a pen for the math problems and crossed things out and often used arows to point out continuation of ideas. i was thinking of scaning a sample of the work but i so don't want to go into that file cabinet.

 

Another "problem" is that in quite a few cases an invention is rather a process that involves many "parents". As the computer was already mentioned here, let me show you two coins that honor people who in one way or another contributed to the development of the computer: John von Neumann (or Neumann János) and Konrad Zuse. Nice designs, and if there was a Hall of Computer Fame, they would both be there - but along with many others.

I'm not in favor of depicting an invention in a coin. However, the Sketchpad was more revolutionary than the ballpoint pen...

I use fine point felt tip pens exclusively in coin collecting for marking 2x2 holders.
Ball point pens are worthless to me.---John
