Nick, your paper looks interesting. From what I understand it tries to analyze
the group selection metaphor. Metaphors are a natural tool we use to understand
abstract objects. To understand a complex problem knowing the tool is
important, but it also helps to understand the underlying processes
Hi Nick,
Yes, wonderful questions all. You are right to guess that there is an ocean of
literature. The entire part that I will know about will be akin to the
atmosphere on a neutron star relative to the whole. So I’ll choose anecdotes.
The most efficient way to get an idea of how much has b

Here is photographic evidence that Dave West is alive, well, and (was)

So... I'm familiar with both Reynolds and Mach from my days at Lockheed.
But Mach, as I (probably don't) understand it, is tied to sound only because
that's an indirect measure of the medium's compressibility, sound being
compression waves. In thinking about these "low Reynolds number" organ
Speaking of Reynolds numbers?
A great many years ago I had an undergraduate honors student who wanted to work
with slime molds. These are social single celled organisms that, when things
get tough, flow together to form a stem and a fruiting body. From the fruiting
body are distributed spores

Actually I agree with you to a considerable extent.
Let us consider Edward's book, On Amazon-India his book (the 7th edn) is
available to us at a Kindle price of approx $9.50. Amazon sells the same
Kindle book in China at $45 and at $155+ for Kindle in the USA.
What does this suggest to you
The concept of "embedding" is probably helpful here:The coastline of Britain is
an embedding of a 2-dim object (a coast) in a 1-dim object (a line). Like a
4-dim hypercube that looks complex because it is embedded in a 3-dim
space.Likewise a group can be seen as a 2-dim object (natural + cultura
Sarbajit, I appreciate your perspective. I didn't realize that India's
constitution declares it to be a socialist state. Perhaps India could be
cited more often as an example of socialism actually working in an advanced
democracy, alongside capitalism.

I don't know why I inverted the Mach number. [sigh]
What do you mean "when things get tough"? Wikipedia says when food is in short
supply. But that sounds like the trigger to become social and, once collected,
there might be another (set of) trigger(s) to reproduce? Or is it the case
that, once
Sarbajit,
You are just touching the surface of how authors are not making profits.
If a book is sold in a college bookstore (all of which rip off students) I get
my contractual royalties (18% of net which is about 80% of gross). Sounds good
but then there are a number of side deals (my six mont
Nick has asked us to consider ways in which society, given its current
structure including sci-hub and libgen, peer network theft, "late stage"
capitalism (including things like Amazon and the gig economy), the decline of
universities, youtube, and everything else, might *facilitate*

Thank you Jon,
Yes, I had forgotten that Purcell did the original of this, and I may not have
seen this particular lecture. (I don’t have recall of the hand pictures.)
What a remarkable guy he was. In almost any topic where he wrote teaching
materials, his are the best version on the subject.
I did not know that either about india. Thanks!
Ed do you get residuals and research royalties from your work? (not to pry)
just curious to get my head around the economics of this.

Hi, US FRIAMMERS,
A recent 538.com blog lamented that voter registration, particularly of new
voters, had collapsed in the US since April. Usually the League of Women
Voters has a recruitment effort around highschool graduations that brings in
a lot of young voters. No graduations, no regist
Sorry, Glen. I left out a crucial detail. Before "things get tough", they
reproduce by cell division. So, each cell has the choice to throw in with the
group, or to continue to reproduce by division. This sets up the "group
selection problem" because only some of the individuals that form t
