Towards the end of the 1800s, there were three primary American groups competing to invent technology to record and play back audio.
Alexander Graham Bell worked with with Charles Sumner Tainter and Chichester Bell in at their
Volta Laboratory in Georgetown, Washington, D.C., while
Thomas A. Edison worked from his
Menlo Park facilities, and
Emile Berliner worked in
his independent laboratory in
his home. To secure the rights to their inventions, the three groups sent samples of their work to the Smithsonian. These recordings became part of the permanent collections, now consisting of 400 of the earliest audio recordings ever made.
But knowledge of their contents was limited to old, short descriptions, as the rubber, beeswax, glass, tin foil and brass recording media are fragile, and playback devices might damage the recordings, if such working devices are even available. That is, until
a collaborative project with the Library of Congress and Lawrence Berkeley National Laboratory came together to make 2D and 3D optical scanners, capable of
visually recording the patterns marked on discs and cylinders, respectively.

Theory of the Origin, Evolution, and Nature of Life, in which the author, Erik Andrulis, proposes an "axiomatic, experimentally testable, empirically consistent, heuristic, and unified theory of life." He also claims to be able to unify physics.....ahem. All this is done using the chemistry notation you learned in highschool.

Professor Brian Cox (previously 1 2) goes unplugged in a specially recorded programme from the lecture theatre of the Royal Institution of Great Britain. In his own inimitable style, Brian takes an audience of famous faces, scientists and members of the public on a journey through some of the most challenging concepts in physics.

So you wake up tomorrow morning to find almost everyone on Earth missing.
The Internet will continue to work for a few hours: what information could you download to ensure your survival and rebuild civilization? A few suggestions:
The CRC Handbook of Chemistry and Physics.
Third Word Development (18 GB of information on agriculture, livestock, food processing, construction, water, sanitation, health and much more).
The Global Village Construction Set (previously). Copies of
Gray's Anatomy,
Where There Is No Doctor, and
The Ship Captain’s Medical Guide.
A few more that might be handy even in ordinary times: all of
Wikipedia, or perhaps
just a portion. (Ideally, of course, you’d already have a
bound, printed copy),
Offline Google Mail (Chrome) to save correspondence;
SiteSucker to download sites you’d like to keep around while offline.

whitney music box -- a fantastic animation You may notice some interesting links between the visuals and the audio, especially if you are a musician. For example, when the pattern forms a 3-arm starfish, the chords you are hearing are diminished chords, which consist of minor thirds, an interval in which the notes are 3 chromatic steps apart. The chords you hear always bear this type of relationship to the pattern you are seeing, consisting of intervals which match the arrangement of arms.
Really, just look, and you'll get it.

CERN has begun webcasting a public seminar in which there may or may not be some announcement regarding the significance or otherwise of recent observations regarding the possible existence of something that might be the Higgs boson. I am not a nuclear physicist, so I will try and keep up but will mainly be trying to catch the significance of the observations they have collected so far. In case these are talked about in terms of sigmas (there's scuttlebutt going around that this is a 3.5 sigma event),
here's a table of sigma and probability.

One of my favorite
blogs happens to be local to me. Eric Berger, the Houston Chronicle's "SciGuy" usually reports on the
weather. But he also posts entertaining and serious stuff as well.

Here is a nice wee video that visualises special relativity; not by imagining the viewer to be travelling very fast, but rather by imagining the speed of light to be very slow. The creators of the code used to generate the images in the video have a rather accessible paper explaining the physics behind it
here, and a page full of other lovely relativistic odds and sods
here.

Three years ago, a question was posed to two
Internet forums. Could you build a wind powered vehicle that could travel downwind, faster than the wind? The lines were quickly drawn and the battle was on, including
here on the blue. It took nearly two years for the debate to be settled, and on July 2, 2010, what seemed impossible was
achieved. The answer is
yes,
you can.

Dissolve my Nobel Prize! Fast! It's 1940. The Nazis have taken Copenhagen. They are literally marching through the streets, and physicist Niels Bohr has just hours, maybe minutes, to make two Nobel Prize medals disappear.

TV Fact Checkers "Behind every smart TV show, there is a tireless script coordinator, technical adviser, researcher or producer who makes sure the jargon is right, the science is accurate and the pop culture references are on-point." This week, Wired "is speaking with fact-checkers behind the fall TV season’s geekiest shows."

Physicist Freeman Dyson reviews two new books about Richard Feynman, one about the science and one in
graphic novel form.
He never showed the slightest resentment when I published some of his ideas before he did. He told me that he avoided disputes about priority in science by following a simple rule: "Always give the bastards more credit than they deserve." I have followed this rule myself. I find it remarkably effective for avoiding quarrels and making friends. A generous sharing of credit is the quickest way to build a healthy scientific community.

"The conventional wisdom, promoted by government and echoed
by the subservient media, is that UFOs are mysterious objects
which by definition are unknowable. Anyone attempting to explain
them is a charlatan perpetrating a hoax and using 'junk physics' .
That may not be so."

Larry Gonick is a veteran American cartoonist best known for his delightful comic-book guides to science and history, many of which have previews online. Chief among them is his long-running
Cartoon History of the Universe (later
The Cartoon History of the Modern World), a sprawling multi-volume opus documenting everything from the Big Bang to the Bush administration. Published over the course of three decades, it takes a truly global view -- its time-traveling Professor thoroughly explores not only familiar topics like Rome and World War II but the oft-neglected stories of Asia and Africa, blending caricature and myth with careful scholarship (cited by
fun illustrated bibliographies) and tackling even the most obscure events
with intelligence and wit. This savvy satire carried over to Gonick's
Zinn-by-way-of-
Pogo chronicle
The Cartoon History of the United States, along with a bevy of
Cartoon Guides to other topics, including
Genetics, Computer Science, Chemistry, Physics, Statistics, The Environment, and (yes!)
Sex. Gonick has also maintained a few sideprojects, such as
a webcomic look at Chinese invention,
assorted math comics (
previously), the
Muse magazine mainstay
Kokopelli & Co. (featuring the shenanigans of his
"New Muses"), and
more. See also
these lengthy interview snippets, linked
previously. Want more? Amazon links to the complete oeuvre inside!

A
new paper by
William J. Bruno of the Theoretical Biology & Biophysics group at Los Alamos National Laboratory argues that past arguments about the impossibility of biological tissue damage from cellphone signals have failed to consider a quantum effect whereby multiple photons in a small volume can have constructive interference, and that such an effect likely does occur in practice.
