Combing two posts: Blankface (Scott Aa) and Is Science Slowing Down? (Scott Al)

(I also posted this to the Less Wrong Website. At least I tried to- I don't quite know if or when it will appear there as its my first post there.) Some papersblankfaces...

Do Four Colors Suffice?

(Guest Post by David Marcus)Comment by Bill: Haken and Appel proved that all planar maps are 4-colorable. Or did they? David Marcus emailed me that its not quite...

I wish problems I have with computers really were my fault

 As you know, the website for out for a few days, as Lance explained here.When I first could not get to the this blog  my thought wasOH, I must have changed some...

Would you take this bet (Part 2) ?

 Recall from my last post (here)I offer you the following bet: I will flip a coin.If  HEADS you get 1 dollar and we end there.If TAILS I flip againIf  HEADS you...

Would you take this bet (Part 1) ?

 I am going to present a well known paradox (I didn't know it until last week, but the source I read said it was well known) and ask your opinion in this post,...

Someone thinks I am a fine artist! Why?

A while back I got an  email asking me to submit to a Fine Arts Journal. Why me? Here are some possibilities:1) They were impressed with my play: Sure he created...

I went to the ``debate'' about Program Verif and the Lipton-Demillo-Perlis paper

On Thursday June 17 I went to (on zoom- does that need to be added anymore?)A Debate on Program CorrectnessThere was no subtitle but it could have been:Have the...

When do you use et al. as opposed to listing out the authors? First names? Middle initials? Jr?

 If I was refering to the paper with bibtex entry: @misc{BCDDL-2018,  author    = {Jeffrey Bosboom and               Spencer Congero and               Erik D. Demaine...

What is a natural question? Who should decide?

(Thanks to Timothy Chow for inspiring this post.)My survey on Hilbert's Tenth Problem(see  here) is about variants of the problem. One of them is as follows: For...

Why do countries and companies invest their own money (or is it?) in Quantum Computing (Non-Rhetorical)

 There have been some recent blog posts by Scott (see here) and Lance (see here)  about the hype for SHORT TERM APPLICATIONS of Quantum Computing, which they both...

Trump, Facebook, and ComplexityBlog

 I care about the Facebook decision to ban Trump, but I do not have a strong opinion about it. I have heard arguments on both sides now, from up and down, and still...

The Mythical Man-Month, Hen-Day, and Cat-Minute (Fred Brooks Turned 90)

 The Mythical Man-Month is a great book which talks about the (obvious in retrospect) fact that putting more people on a project may slow it down. It was by Fred...
