Abraham Lincoln Quote

I'm making my way through Susan Jacoby's book, Freethinkers, A History of American Secularism and just came across a quote by President Abraham Lincoln that just drips of the kind of well-reasoned intellect that is so absent from the modern political arena. Jacoby remarks on Lincoln's notoriety for being painfully slow in making decisions. In one instance, shortly before issuing the Emancipation Proclamation, Lincoln responds to the demands of a group of Chicago Christians for an immediate resolution. He says,

"I am approached with the most opposite opinions and advice, and that by religious men, who are equally certain that they represent the Divine will. I am sure that either the one or the other is mistaken in that belief, and perhaps in some respects both. I hope it will not be irreverent for me to say that if it is probably that God would reveal his wills to others, on a point so connected with my duty, it might be supposed he would reveal it directly to me; for, unless I am more deveived in myself than I often am, it is my earnerst desire to know the will of Providence in this matter....These are not, however, the days of miracles, and I suppose it will be granted that I am not to expect a direct revelation. I must study the plain, physical facts of the case, ascertain what is possible and learn what appears to be wise and right."

Its hard to imagine conceive conjure-up dream of George W. Bush ever being able to deliver such an eloquent statement, much less write it himself. Actually the thought of him even trying to read this statement aloud is worth a good laugh. But more to the point of the substance, I think that the reason I can't even picture Bush enunciating these words is because the very spirit of what Lincoln is saying here runs contrary to everything that Bush apparently believes.

Spider Ship - Proteus




















By way of the San Francisco Chronicle comes this article on El Cerrito Marine Advanced Research's PROTEUS watercraft. Looks like it was inspired by nature:

Labreporter film: LHC at CERN

Today's Daily Zeitgeist over at SeedMagazine.com points the way to a video done by Labreporter, detailing some of the work being done in preparation for the LHC (Large Hadron Collider) at CERN .



The video documents the manufacturing of some of the measuring and detection instruments being built by researchers at the University of Liverpool for the LHC. The focus is on the "clean room" - one of the cleanest in the world, apparently, with less than 100 particles of dust per cubic meter of air.

The size of the stars

First there was this webpage
and now this video - I've already watched it half a dozen times:

"Its something like one followed by twenty-three zeros..."

Carl Sagan was really good at expressing wonder and awe at the immensity of the cosmos. I've just started reading The Varieties of Scientific Experience Amazon, B&N, LoC.
Early on in the book Sagan introduces us to the galaxy by way of some stunning images of our solar system, and nearby star clusters. And then he drops the hardly modest number of stars in our galaxy. About four hundred billion. 400,000,000,000 Hardly modest indeed. You can now buy a 400GB harddrive (yep, four-hundred billion bytes) on ebay for about 100 bucks. Well, as it turns out, the number of galaxies in the universe is likely to be even greater than the number of stars in the Milky Way galaxy, so we have something like 100,000,000,000,000,000,000,000 stars in the known universe.
For the sake of argument, lets say that there is only one planet in orbit around each of these stars. Would you bet that the chances of intelligent life arising in the universe are in fact only one in 10^23. The odds of winning the DC Powerball lottery this week are 1:146,107,962; if we really are alone in this immense universe, what a waste of space indeed.

The one-sentence future challenge

By way of Janet D. Stemwedel at [ Adventures in Ethics and Science ] and Dave Munger [ Word Munger ] comes a nice little internet meme posed by Paul Kedrosky:
Physicist Richard Feynman once said that if all knowledge
about physics was about to expire the one sentence he would tell the
future is that "Everything is made of atoms". What one sentence would
you tell the future about your own area, whether it's entrepreneurship,
hedge funds, venture capital, or something else?
Examples: An economist might say that "People respond to incentives". I had an engineering professor years ago who said all of that field could be reduced to "F=MA and you can't push on a rope".
Link here

I'm going to give that one some thought - I'd like to think that I could sum up the importance of all scientific endeavor in a nice little easy catch-phrase, but then again science isn't about all the easy answers.

WHY?

Apparently the US flag decal raised on some of the first Freedom Tower columns was backwards. No, not like looking at the word "Ambulance" in your rear-view mirror backwards. The stars were on the right side of the image, instead of the left. Ruh Roh? CNN has the story here



Federal flag code requires that the stars be on the left side of the viewer. I cant think of many more inconsequential things to dream up for US law/policy than that. Maybe back in the early wars of this country, the placement and direction of a flag on the battlefield had some practical meaning - but do we really need to adhere to such a trivial practice today?

Celebrating Sagan

Just in time to honor the passing of Carl Sagan 10 years ago tomorrow (Dec 20), a number of bloggers have put together the Celebrating Sagan blog. They've solicited thoughts of bloggers around the 'sphere and a lot of the posts that have come in are genuinely moving.

The posts range from sound-bites from interviews and lectures that he gave over a long and fruitful career to video clips of his work to inspiring letters thanking him for his contributions to science. Personal thank-you notes to Sagan also serve to remind readers of just how much of an influence on life and career choices Carl really was.

I think that Kurt Vonnegut's words, on the back cover of Sagan/Druyan's most recent work "The Varieties of Scientific Experience" are just as aptly applied to this webpage:

" Find here a major fraction of this stunningly valuable legacy left to all of us by a great human being. I miss him so."
