You might recognize Ken Nordine's voice from TV commercial and movie trailer voiceovers. What you might not know about is his musical work that he called "word jazz". This included several LPs and a long running radio show on NPR, one of which is linked in this submission.

He would sometimes include work from other artists in the background. In this particular program, there is a woman who can be heard singing starting at around the 3:50 mark. I'm wondering if anyone knows the name of the singer? I haven't had much luck finding any sort of credits or other information about these broadcasts.

Intro to the PBS show MYSTERY! using animation of Edward Gorey.

This is an analysis I did some time ago comparing FIDE ratings to lichess ratings. The biggest part of the work was finding a reliable way to get both ratings for the same set of players. A lot of players on lichess post their FIDE ratings, but unfortunately, some players will post joke ratings, or just outright lie.

In order to avoid "liar's bias" in the self-reported FIDE ratings, I used two different methods to independently look up FIDE ratings directly from FIDE. In the first method, I took advantage of the fact that many lichess users post their FIDE ID numbers to their lichess profiles, enabling direct lookup of their ratings. In the second method, I used lichess profile data to create a "key" consisting of name, title, and country. In cases where the key is unique, and is present in both the lichess and FIDE data sets, I can then look up the FIDE rating for that user. Finally, to ensure I have the correct player, I only keep the data point if the player's self-reported FIDE rating matches the one I looked up.

Out of 628,200 lichess profiles, I was able to harvest 5957 FIDE ratings. This is plenty of data for looking at the overall correlation between the two ratings.

It turns out, there is a large spread present in the ratings data. In other words, if you know someone's rating in one system, your estimate of their rating in the other system will be very imprecise. To give people a better feel for how (un)reliable the estimates are, each graph here shows scatter plots of FIDE standard ratings versus the various ratings for different lichess time controls. The red line in each plot is a robust linear regression of the data, while the blue lines show quantile regressions for the 97.5, 50 and 2.5 percentiles. In other words, 95% of players fall between the two dotted blue lines. For example, about 95% of players with a lichess blitz rating of 2500 will have a FIDE standard rating between about 2000 to 2500, so if you have a blitz rating of 2500, you could roughly estimate your FIDE as 2250 +- 250. Note that even though this is about the tightest correlation shown, the precision isn't great. Apparently people just vary a lot. Maybe it has something to do with skill playing online not being quite the same as playing in person.

One rather unexpected thing that stands out in the data, is that the correlation is worst at the fastest and slowest time controls. Since most lichess time controls average less than 25 minutes per game, compared to FIDE's typical 90 minutes for the first 40 moves, I was surprised to see that blitz has the tightest correlation.

Here are the linear regression coefficients, since I'm sure someone will ask for them (x indicates the slope):

``` [1] "ultraBullet" Coefficients: (Intercept) x 1265.331 0.473

[1] "bullet" Coefficients: (Intercept) x 722.0768 0.6261

[1] "blitz" Coefficients: (Intercept) x 41.4256 0.9074

[1] "rapid" Coefficients: (Intercept) x 309.9946 0.7962

[1] "classical" Coefficients: (Intercept) x 1161.4994 0.4038

Pare Lorentz's poetic documentary film The River (1937) tells the story of how agricultural practices along the Mississippi river led to topsoil loss and flooding during the depression era, eventually leading to soil conservation practices and dam construction. Flooding broke out on the Ohio river during filming, and is stunningly documented in the film. The film premiered in New Orleans on October 29, 1937.

The poetic narration was praised by James Joyce and Carl Sandburg. A companion book to The River was nominated for a Pulitzer prize in poetry.

The film was awarded best documentary at the 1938 Venice International Film Festival. Virgil Thompson's score is a classic that was used again as the score to the 1983 film The Day After. The River is listed in the Library of Congress National Film Registry.

This film documents the rush to repair damage to the tunnel spillways of the Glen Canyon Dam that were damaged when they had to be used for the first time in 1983 due to record-breaking runoff into the Colorado river. As repairs were taking place, waters again began to rise in Lake Powell in 1984, creating a race against nature to finish repairs in time.

I saw this film decades ago at the Glen Canyon Dam visitors center, and it always stuck with me. The film includes references to the classic 1937 documentary The River about floods on the Mississippi.
