Re: Find the value

Cracking codes?

Re: Find the value

What were computers invented for, then?

That is one of the first reasons but the other side was using them for a much more ghastly purpose.

But the very, very, very first use was done by good ole Charlie Babbage. Him and Ada were going to use it compute difference tables.

Re: Find the value

Well, breaking codes require a lot of math, I suppose?

Re: Find the value

The attack on the Enigma machine was actually begun before that by a group of Polish mathematicians. Alan was the first guy to use a computer to implement those ideas.

Re: Find the value

Is the enigma broken?

Re: Find the value

Yes, there is a great book by Hodges that describes in some detail Alan's work and story.

Re: Find the value

Why is it important to break the enigma?

Re: Find the value

Transmissions to the Luftwaffe, Wehrmacht and the Navy were all sent in code. The code was generated by the Enigma machine.

Re: Find the value

Yes, it does. I will work on it when I get there.
