Happy New Year and Network with Thomas Jefferson

Happy New Year from Asheville.

While you’re recovering today, compare your library to Thomas Jefferson’s (and join LibraryThing while you’re at it… it’s my fav social network):

A unusual member has finished adding his 4,889 books to LibraryThing—our third president, Thomas Jefferson!

Jefferson, 264, was assisted by sixteen LibraryThing members, led by jbd1. Together, they cataloged 4,889 books (6,487 volumes), added 187 of his reviews (a treat), and tagged them 4,889 times, according to Jefferson’s own innovative/weird classification system.

It was hard work, but it only took them four months. They worked from scholarly reconstructions of Jefferson’s 1815 books, tracking down records in 34 libraries around the world. As is well known, Jefferson sold his books to the Library of Congress, replacing the one the British destroyed during the War of 1812. This 1815 library is Jefferson’s best-documented library. (Of course, Jefferson spent the rest of his life building up another personal collection.)

LibraryThing: Happy 1815! Thomas Jefferson in done.

In Memory of Carl Sagan

Today is the 11th anniversary of the death of my hero Carl Sagan (thanks to Bad Astronomy for the reminder).  Personally, it has been an emotionally trying year with the birth of our first child and soon thereafter the death of my childhood best friend and cousin (more like brother) in Afghanistan. I find wisdom in Dr. Sagan’s words about life, the cosmos and humanity today.

Echoing my post from a year ago, here’s the passage from Cosmos which I’ve read at the end of every class I’ve ever taught… whether science or religion bound:

“The Cosmos is all that is or ever was or ever will be. Our feeblest conemplations of the Cosmos stir us – there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.

The size and age of the Cosmos are beyond ordinary human understanding. Lost somewhere between immensity and eternity is our tiny planetary home. In a cosmic perspective, most human concerns seem insignificant, even petty. And yet ourspecies is young and curious and brave and shows much promise. In the last few millenia we hav emad the most astonishing and unexpected discoveries about the Cosmos and our place within it, explorations that are exhilarating to consider. They remind us that humans have evolved to wonder, that understanding is a joy, that knowledge is prerequisite to survival. I believe our future depends on how well we know this Cosmos in which we float like a mote of dust in the morning sky.

Those explorations required skepticism and imagination both. Imagination will often carry us to worlds that never where. But without it, we go nowhere. Skepticism enables us to distinguish fancy from fact, to test our speculations. The Cosmos is rich beyond measure – in elegant facts, in exquisite interrelationships, in the subtle machinery of awe.

The surface of the Earth is the shore of the cosmic ocean. From it we have learned most of what we know. Recently, we have waded a little out to sea, enough to dampen our toes or, at most, wet our ankles. The water seems inviting. The ocean calls. Some part of our being knows this is from where we came. We long to return. These aspirations are not, I think, irreverent, although they may trouble whatever gods may be.”

And here’s the video version:

This being my first year with a child, I can only hope that I pass on to her the wisdom, confidence and humbleness to always look up at the night sky. 

Thank you, Carl Sagan.

Learning, Teaching and the New Web

Last week, my grad school alma mater Yale opened its doors to the web and followed the path of Stanford and M.I.T. by putting popular courses up for anyone to enjoy and learn from.

Here’s a great story from the NY Times about an amazing Physics teacher at M.I.T. who is using this newfound access to people outside the ivory towers to share his love for physics:

Professor Lewin’s videotaped physics lectures, free online on the OpenCourseWare of the Massachusetts Institute of Technology, have won him devotees across the country and beyond who stuff his e-mail in-box with praise.

“Through your inspiring video lectures i have managed to see just how BEAUTIFUL Physics is, both astounding and simple,” a 17-year-old from India e-mailed recently.

NY Times: At 71, Physics Professor is a Web Star

Thanks, Anna

Chris Brogan wished his wife a happy birthday in a beautiful post on his blog today.

Following in his footsteps, I just wanted to give a quick “Thank you and I love you” to my wife. It has certainly been one heck of a year, but she impresses me more and more everyday with her skills as a physician, friend, wife and (now) mother…

Here’s to the next 50 holiday seasons!

Celebrating Five Years of Blogging: SkyHawkScience Still my Fav

Robert Scoble has started a fun trip down memory lane for all of us with his post “Celebrating Seven Years of Blogging.”

I formally started blogging in 2002 with Digital Moses then the relaunched ReveNews (my pal Jim Kukral was publisher of ReveNews at the time and has been blogging since 2000 or so). But the blogging that I’m most proud of was the class blog I started while I was teaching 8th Grade Physical Science at Hammond School in Columbia, SC. The blog was called SkyHawkScience and was a tremendous experience. I still tear up when I look at the archive on Internet Archive (took the site down because after I left teaching I didn’t want the blog to forever dominate my students’ Google indexes since it did gain popularity).

I still miss that blog. I’ve gone on to blog at CostPerNews, ReveNews again, HarrelsonReligion (my college class blog) and here (first on wordpress.com then as a hosted WordPress blog). I still like the SkyHawkScience blog the best, though.

Super Roman Glue

First concrete, now superglue… is there anything the Romans didn’t engineer?

I’m sure the location that this glue concoction was recovered had something to do with its makeup (much as Roman concrete varies from place to place based on location of origin in the Empire). However, this is still pretty amazing considering the time gap:

Analysis shows that the Roman glue was made of bitumen, beef tallow and pitch. But researchers said they had failed so far to recreate the adhesive and that sawdust, soot or sand might have to be added to complete the process.

“When we finally manage to remake the superglue, it will easily compete with its modern equivalents,” Mr Willer said. “After all, which of today’s glues stick for 2,000 years?”
