Darwin in the Air

You’ll begin to notice a lot of discussion of Charles Darwin soon. Why? It is his 200th anniversary, and also 150 years since his Origin of Species was published, and so many people and organizations will be celebrating those landmarks. I did a couple of posts last year on Darwin that are worth a look, one about Darwin’s presentation of the evolution idea to the Linnean Society (150th anniversary of that last year) and the other about the wonderful Darwin Online project. See here and here.

Earlier this week I noticed that BBC Radio 4’s excellent series In Our Time (which I’ve mentioned a number of times here and will again) did a four part special documentary on Darwin. I’ve not listened to it yet, but I’ve a feeling it’ll be good. (I’ll be dropping all four parts onto my phone for listening to in those idle moments on some travel I’m about to embark upon.)

Snipping some of the synopses: […] Click to continue reading this post

Presidential Poetry

More encouragement (see my earlier piece about education and about science and more science) comes around the matter of poetry and the presidency. Larissa Anderson, on Weekend America this Saturday, reported on the president-elect’s evident interest in poetry. Derek Walcott was featured in the piece as well (I was pleased to hear this since I like his work, and it is also good to hear about the work of a Caribbean thinker on the national stage – it does not happen often enough for my liking) and had some very interesting things to say. From the transcript of the piece (see that link for audio):

Walcott says it’s good for people in power to read poetry because human beings are complex and contradictory, and poetry can capture that. Like in Langston Hughes’ poem “Theme for English B” when the black student writes to his white teacher, “Sometimes perhaps you don’t want to be a part of me. / Nor do I often want to be a part of you. / But we are, that’s true!” Or in Walt Whitman’s line, “I am large — I contain multitudes.”

Walcott likes the idea of a president who reads poetry and thinks about this kind of human truth. Someone who can see beyond the act of political posturing.

Then he read his recent poem, “40 Acres” that he wrote for Obama, which I thought was rather good. He also described some of the process of writing it – also excellent to hear. Finally, the piece reported on something he said that reflects my own […] Click to continue reading this post

Thermodynamics and Gravity

ads_ballI noticed that Robert Helling shared some thoughts about thermodynamics and gravity today on his blog. He is understandably confused about several aspects of the issue, especially when applied to cosmological issues. (What is the entropy of our universe? Does the Second Law really apply? Does equilibrium thermodynamics even apply here?)

I’ve nothing remarkable to add to the discussion at this time except to note that a blanket statement that thermodynamics and gravity don’t seem to go together (which I don’t think he’s strongly saying) is not one I’d make, since we have a major class of working counterexamples.

The context is the gauge/gravity duals I’ve talked about here a lot, starting with AdS/CFT and beyond. There we know that the gravitational systems are essentially able to display the more garden variety thermodynamics by being immersed in the (regulating-box-like) anti-De Sitter type backgrounds. Then we see that black holes […] Click to continue reading this post

Merry New Year!

pods on a tree at new year Yes, that’s right. You read Merry and not Happy.

I’m breaking the mould. I’m upping the stakes. I’m wishing one and all a year of merriment. I’m afraid it can’t be returned, so you’ll have to work with it as best you can. I’m certainly going to.

To achieve the mean of Happiness that the millions of Happy New Year wishes every year are evidently striving for, we need to be aiming for some Merriness from time to time to keep us on track at settling at this particular position on the multidimensional emotional landscape.

Someone has to take this important business in hand, and so I’m having a go, […] Click to continue reading this post
