It has been mentioned here before I think. Try also the Meccano/Erector difference engine it was based on. Or better explore the entire site. I believe Tim is working on the Babbage analytic engine at the moment.

I could have sworn it was mentioned here before, but if it was, I can't find it. Oh, well, I must have seen it while idly browsing woz.org many moons ago.
A LEGO difference engine is not an HP calculator, but it is so cool that I'm going to say Thank You for pointing it out anyway. :-)

A famous quote from Babbage

Hi, Luiz --

A famous quote from Charles Babbage:

Quote:
On two occasions I have been asked, – "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" In one case a member of the Upper, and in the other a member of the Lower, House put this question. I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

Thank you! A pure gem!

So that was the kind of thought Babbage´s difference machine caused the members of the House (of the Lords, I presume) to be bothered with. Poor Babbage... extra wondering and worriness.

Thanks again.

Luiz (Brazil)
