The First Pseudorandom Generator--Probably

(The following was told to be by Ilan Newman at Dagstuhl 2009. His source was the book The Broken Dice and other mathematical tales of chance.)   What was the...

When is a theorem really proven?

One of the comments on this blog pointed out correctly that for a theorem to be accepted by the community is not a Eureka Moment. It is a social process. The author...

Job Postings

Two sites to look for jobs at: Lance Fortnow set up this blog that collects theory annoucments including jobs: here Boaz Barak Obama, in an effort to create...

Two Theorems this blog missed

I warned Lance to wait until early Jan to post 2009 Complexity Year in Review. It was my fear that by posting it on Dec 28, 2009 he may miss out if someone proves...

Should CCC2012 be at the North Pole?

The last few posts on ICS in China have lead to off-topic (though maybe they were not off topic) comments on whether we should have conferences in countries who...

Do Innovative papers have a hard time getting into STOC and FOCS? I ask this objectively with no ax or teeth to grind.

(This is my last post until next week Tuesday.) Many people believe the following: FOCS and STOC only take technically hard results on problems that we already...

ICS I: snapshots and the longer view (guest post)

(Guest Post by Rahul Santhanam) Title: ICS I : Snapshots & The Longer View 1. Local Arrangements: Kudos to the organizing committee for going far beyond...

COLT and CCC

The COLT (Computational Learning Theory) call for papers is out. (Actually its been out since October but I was only recently emailed it.) For other information...

DO NOT do this when choosing books for your class

When I took my first graduate course in complexity theory the professor had FOUR books on the REQUIRED FOR THE COURSE list. I bought all four. He said that We...

Axioms: What should we believe?

Some misc thoughts on set theory inspired by yesterdays comments and other things. Geometry: Use Euclidean Geometry when appropriate, for example if you are So...

Voting on Mathematical Truths: The Axiom of Det.

One of the founders of Conservapedia (a conservative alternative to Wikipedia) said the following on The Colbert Report: There is an absolute truth. People don't...

How to tell how good a TV show is

(This is my last blog of the year. Lance will interupt his blog sabbatical to do an END OF THE YEAR blog later.) The TV show MONK recently finished its 8thHow...

What is an Explicit Construction?

The Prob method (usually credited to Erdos) was once considered quite novel: You show something exists but you don't show how to construct it! An early exampleThe...

A hard problem inspired by an easy problem

The following problem was problem 1 (the easy one) on the Maryland Math Competition 2009 (I will later report on how the students did on it). Show that for every...

Guest Post- Women in Theory Workshop

(Tal Rabin requested to post this so I am doing so. This post is essentially her email, so call it a guest post.)   There will be a Women In Theory workshop for...

Mild Request for Guest Posters.

(Deadline to submit a paper to CCC is Dec 15. Depending on when you read this that could be today or in the past.) As you all know from Lance's last post, Lance...

CCC deadline Dec 15, 2009! (not factorial)

Submissions to 25th CCC are due TOMORROW! (Actually it could be TOMORROW, TODAY, or IN THE PAST depending on when you read this.) Should you submit? If you have...
