**A few comments:**

- It’s (just-barely) conceivable that the results could have been
*slightly*skewed by the quantum- and complexity-loving readership of this blog. - Voters
*really*didn’t like fiction/pop-culture references, mechanical contrivances, or anything that sounded like a publicity stunt. They were much keener on conceptual advances (even to the extent of putting Gödel well ahead of the transistor).

I need to catch a plane to give the Buhl Lecture at Carnegie Mellon tomorrow, so I’ll leave you to draw any further conclusions.

Dear Scott: I wish you had trumpeted tomorrow’s lecture at CMU a bit earlier! I live in Des Moines and am going to have to drive most of the night to make it on time…I only hope I’m not too punch drunk from lack of sleep to appreciate the show. Well, got to go gas up the VW and buy some munchies. See you in Pittsburgh!

Maybe I miscounted, but isn’t the 150 mark at either machine translation or Usenet? If so it is amusing that these are the first two entries with negative vote totals.

Kemper: Sorry about that! I had no idea anyone would drive to such a talk from outside Pittsburgh; I would’ve just stayed home and watched it on the web… (I’m flattered, though!)

As far as we can tell Godel’s letter to von Neumann had zero influence on the direction of CS and it gets 106 votes.

VisiCalc which introduced the spreadsheet gets 2 votes.

Hmm…

Another anomaly, in my opinion, is the high position of Euclid’s Elements, as compared to the more algorithmic problem solving oreiented work of Diophantes, Aryabhata, and Al-Khwarizmi for example. Although Euclid founded the “theorem-proof” structure of mathematics, CS in my opinion owes more to the idea of a “mechanical algorithm’ which should not require any “intelligence” to use. Looked this way, I think the development of decimal arithmetic, and general algebraic procedures for the solution of equations is probably much more important in the history of CS.

Amazing, an online poll without a single L. Ron Hubbard or Ayn Rand reference in the top 10!

Yes, could you please clarify where the 150 mark is?

Oh, I feel silly. That’s easy to determine. The 150 mark falls “between” machine translation and Usenet. Except it actually can’t, since they have the same number of votes (-1). So more properly, the 149 mark falls between Egyptian revolution and machine translation/Usenet, and the 151 mark falls between machine translation/Usenet and Akamai, and it’s up to Scott whether he prefers to include machine translation or Usenet for #150…

This is an absurdly academic list! Euclid’s Elements #1? And how is Konrad Suze, inventor of the world’s first functional program-controlled Turing-complete computer, not on this list?? Please try again, this is an obvious fail!

Excuse my dyslexia, of course that should be Zuse!

Sorry, my post was an obvious fail! Dyslexia strikes again!

Alpha Omega: Not only is Zuse on the list, he got 40 votes!

Also, you do realize this was a poll, right? When you say “please try again,” do you want me to try again with a different blog-readership?

Ha yes I that’s why my post was an obvious fail. In any case, I feel that building the first computer deserves to be *much* higher! So yes, maybe a new blog-readership is in order! 😉

Didn’t Kevin Spacey play Konrad Suze in the movie version?

Scott,

I couldn’t find any streams to the talk, you’re sure that there’s one? Only to guests?

Cheers!

How much of a bias was there to Euclid’s Elements by merit of it being at the top of the chronological list? When I saw the page I started voting, but almost stopped (or at least started going much more quickly) once I saw how long the list was

Zuse’s Z1 was not a Turing-complete computer, it was program-controlled, but did only execute straight-line programs without any control structures. The program also was not stored in memory, but fed to the machine on hole-punched film rolls.

Euclid probably enjoyed a little of an unfair advantage since the poll was sorted by time. A better poll would have been randomly sorted differently for every user (though I admit that would’ve have been so much fun). I myself gave Euclid an upvote when I first started, but then later went back and switched it to a downvote (this was before we could cancel a vote) after seeing what kind of stuff it was up against.

Any thoughts about the New Yorker article on quantum computing?

Is your talk online?

If I were Scott, I would throw out the Fischer-Lynch-Patterson theorem (because of the obvious bias towards theory of the poll participants) and stick in both Machine Translation and Usenet. Mike, Nancy, Mike, if you’re reading this, please accept my apologies — I still think it’s a wonderful result.

So how was the Bull lecture?

rr: Not bad! It’s always nice to have an opportunity to spout some Buhl. You can see my slides here; not sure when the streaming video will become available.

From a theory person, it is very depressing to see how narrow-minded people are.

any comment about what appears to be solid peer reviewed proof that Dwave has been leveraging quantum effects (at least quantum annealing) in their adiabatic quantum computer

I visited the MIT museum today with a friend, and yes it could definitely use the timeline. There’s room in the hall!
