The Making the Modern World website
is a great collection of photos exemplifying devices that helped form the world
in which we live. A good example is John Fleming's
diode valve shown here. He invented it in 1904 while at the Marconi
Company. Add a grid to control electron flow and you've got Lee De Forest's signal-amplifying
triode valve (Audion). Edison's Earth-destroying
filament lamp is another example. Have you seen a picture of
Cookes' radiometer rather than just a sketch in your second-semester
physics textbook? Here is Faraday's original
magnet and coil from which he formulated his laws of electromagnetic
induction., This is another one of those websites where once you start browsing
through the images, you will find it hard to stop. You'd better save this one for
Maybe I should pay more attention to what
is on the shelves when going grocery shopping with Melanie. Whilst strolling through
the produce section of the local Wegmans supermarket,
I noticed an impressive example of mathematics in nature called Romanesco broccoli.
Its shape just screams "fractals" at you when you see it. The apparent order and
symmetry is amazing. In all the reading I have done over the years on fractals and
Mandelbrot sets, for some reason I do not recall ever seeing Romanesco broccoli
as an example in nature. Tree leaves, ice crystals, lightning bolts, and even continental
shorelines are often offered, but broccoli? Heretofore when I thought about broccoli,
the stuff that looks like a
brain stem came to mind - not much order apparent in that stuff.
While in general my food preferences were formed and have remained pretty much unchanged
since about age 15, I think sampling some Romanesco broccoli is in order, almost
required. Who knows, perhaps it is a real brain food like fish and seeds and may
even improve my math skills.
Steve Jobs worship is such an established
religion that I'm surprised Apple Computer never received 501(c)(3) status with
the IRS. Buying Apple products could have been deductible as a charitable expense
if the accountants on staff had put a little effort into it. Just like with the
over-zealous religious fanatic in the office break room, I have always felt a little
embarrassed for the person who dotes over his new iPhone or has to constantly remind
us infidels how our PCs running Windows (excuse the bad language) pale in every
aspect compared to his Mac-this, or i-that. When a new version of the MacOS is released,
it is as if a new chapter of the Bible had just been discovered in a cave in Jerusalem.
Now, I wish the best of health for Mr. Jobs, and truly admire his accomplishments,
but let us admit here and now that a large part of his success is due to the unwavering
dedication of iBots. Prosecuted computer hackers are on record for specifically <more
Have you seen the strange patterns imaged
over China's Gobi desert by the Google Earth satellite? It first hit the news cycle
late last week. Unlike the Martian "canals" sketched and reported by Percival Lowell, these surface
marking are not artifacts of a faulty interpretation. The tin hat crowd immediately
concluded that it is evidence that China has been visited by space aliens (too far
for illegal aliens from Mexico to travel), and that is why China has been able to
build up its infrastructure so rapidly in the last decade. Theories also abound
about how the Red Army (red = Communist, yes they are) has heretofore secret ICBM
launch facilities spread throughout the western mountains, just waiting for another
American aerospace company to provide the final
technology needed to launch an offensive against the U.S. In reality,
real experts say they are likely calibration targets for Chinese spy satellites.
The 65'-wide, silver-painted lines follow natural drainage channels in the landscape.
Of course, the U.S. can also use them for alternative calibration to learn how China
sees the world. If you pan widely around the area, you will find all kinds of other
This is a test. One of these offices belonged
to Albert Einstein at the Institute for Advanced Study, at Princeton, New Jersey.
The other belonged to Bob Pease at National Semiconductor. Both photos were taken
very soon after their owner's departures. Don't bother trying to guess the answer
based on an assumption that Pease's office will be easy to spot because there will
be a computer on the desk. Bob notoriously detested computers, and desktop computers
had not been invented in Albert's time. Both men used the same form of PowerPoint
presentations - transparencies on an overhead projector. Both men carried out most
of their laboratory computations with a paper and pencil. The Princeton Professor
had no choice; the Sage of National did so because he believed that new generations
of engineers were quickly losing or never had the ability to analyzed circuits without
the help of a computer. This, of course, invokes the old adage, "If a cluttered
desk is the sign a of a cluttered, mind, what is an empty desk the sign of?
A familiar pipe on an open book, a cluttered desk and a blackboard covered with
mathematical equations surround the empty chair in Dr.
office at the This photo was taken on April 18, 1955, the same day that the
famous physicist died of a gall bladder ailment at age 76.
If you appreciate vintage military radios,
then you will definitely be interested in the collection at the Duxford Radio Society's
display at the Imperial War Museum, England. Racks and shelves there are densely
packed with HF, VHF and UFH radios, oscilloscopes, signal generators, meters, power
supplies, and intercom systems. There is even a flight navigator training simulator.
Most of the gear is British, but there are a few examples of captured German equipment.
Many photos of restored (from non-working condition) and conserved (cleaned and
shined) radios are available, as well as some work in progress. One of the earliest
airborne radar systems, the APS-4, which was mounted under the nose of a Fairy Firefly
of the Royal Navy Fleet Air Arm, is being restored. The frequency used was approximately
9 GHz with a pulse duration 0.6 μS and the pulse repetition frequency adjustable
to either 600 or 1000 cps. The peak RF output power was 40-70 kW. That's pretty
advanced for 1943! I swear the old dude sitting in the chair is sound asleep. I'm
guessing he actually operated or designed some of that equipment.
The idea is interesting, but I believe the
results as presented fall woefully short of real science - certainly not worthy
of a full page in Scientific American without a disclaimer. "Physics or Fashion?
What Science Lovers Link to Most" shows interconnections between Internet visitors
to 600 different science and math related websites and where they are likely to
go from there. The chief scientist at "bitly" (they create shortened URLs) plotted
information gleaned from their users to conclude, for instance, that people who
frequent technology visit fashion website upon leaving, while visitors of religion,
chemistry, and statistics websites have little interest in fashion (ok, well, we
don't need a formal study for that conclusion). Many problems with the methodology
are apparent, the most glaring of which is the extremely limited sample size (<0.0000001%
of Internet users) over an extremely limited time (2 days = 0.6% of year), using
only their clients' data. My guess is most paths to fashion and health websites
come from Google type banner ads. What are those ads likely to show in August? Girls
in swimsuits and halter tops, and pharmaceuticals offering miracle 4800Å pills.
Click, click, click. Let's face it, most patrons of tech websites are male, many
of which are held captive inside labs and cubicles all day and all week long. It's
a nice picture, but we need more data.
Warning to Apple supremacist sycophants (Ass):
This smartphone story does not feature an iPhone. It is about an amputee who had
a custom prosthetic arm made to hold his
Nokia C7. Trevor Prideaux was born without a left arm. Being the
manager of a catering service, he relies heavily on his smartphone for schedules
and contacts. As you can imagine, holding the phone with a claw while pressing buttons
was cumbersome and time consuming. So, Trevor solicited the assistance of Nokia
and prosthetists at the Exeter Mobility Centre. "My Nokia C7 sits within my forearm
between my stump socket and the single knob rotary that holds my limb attachments
in place. Now when I get a call, I can either hold my arm up to my ear or put it
on speakerphone. I can also take it out if I need to." Apple, btw, was contacted
first but refused to help; Nokia assisted gladly. If you are an Ass and
read this anyway, you might need to take a pill and lie down now.
20 Companies. 30 Years. 575,457 Jobs. That
is the title of this chart published by Inc. magazine demonstrating how
fast-growth start-ups are major job creators. It's not just the Oracles - 38 employees
in 1984 to 104,500 in 2011 - that have given thousands of people work over the years.
Papa Johns pizza chain had 40 employees in 1991 and today has 16,000. Their story
is printed on the side of their pizza boxes (at least the last time I bought one
it was). That pales in comparison to Domino's Pizza, who went from 500 in 1983 to
145,000 in 2011 - that beats Oracle. Qualcomm went from 436 employees in 1991 to
15,106 this year. Intuit, the TurboTax and QuickBooks people, grew from a staff
of 110 in 1983 to 7,700 this year. You will probably recognize everyone on the list.
These 2011 numbers are probably lower than they were a couple years ago due to a
lot of layoffs, particularly for the tech companies. Many executives from top companies
like these say massive, burdensome government regulation is killing their established
businesses, while impeding and even preventing new start-ups from succeeding. While
whining publically about lack of job creation, the politicians continue to pass
laws guaranteeing things will never get better, and then send neo-hippies to Wall
Street to protest.
You probably immediately recognized this as
a simple deterministic model illustrating the geomagnetic reversals. I know I did
(not). It's one of those strange attractor phenomena that goes by the title
Chaos and Geomagnetic Reversals. I have to admit, though ,that The Buddy
System: Two Fish Swimming Side-by-Side had me stumped. These and other images
are part of Princeton University's annual "The Art of Science" contest. The 2nd
place entry from the Electrical Engineering department titled Tree, illustrates
software for a deconstruction algorithm that splits images into sub-images in a
way that best captures important structures. Per Mr. Xiang, "For each input image,
our algorithm finds the dyadic tree that gives the most concise representation of
the image as measured by its Haar wavelet transform coefficients computed on this
tree." Makes sense... why didn't I think of that?
No, it's not an insect egg. This is a top
view of the U.S. Air Force's latest monster airship, codenamed "Blue Devil Block
2." If you click on the thumbnail, you will see a tiny truck off to the left; that's
an 18-wheeler tractor trailer! Sporting a 370-foot length and containing 1.4 million-cubic
feet of helium, this blimp will be "parked" at an altitude of up to 20,000 feet
near battle zones. Its massive suite of surveillance will include multiple types
of radars, and optical, acoustic, and electromagnetic listening devices, covering
as much as 36 squares miles. It can remain airborne for up to five days at a time.
Though designed to operate remotely as an unmanned platform, it is capable of hosting
a human crew. MAV6, a somewhat stealthy group, seems to be the architect and
builder. According to their website, Blue Devil Block 2" is an "airship-based C4ISR
aerial fusion node (and weapon system platform) integrating multiple distributed
and local sensors with on-board processing ! into a common operating picture!."
I sure hope the thousands of missing shoulder-launched missiles from Libya can't
fly that high!
Update: BroadbandMap.gov has gone offline;
a copy of it can be seen on
Archive.org. An explanation of its disappearance can be found at MyMove.com's article,
Happened to BroadbandMap.gov?" The U.S. government has published a series of
National Broadband Maps that present various statistics on Internet service. The
one shown in this thumbnail covers consumer broadband test speeds versus advertised
speeds. Red indicates slower than advertised, green better than. Notice that at
this scale you cannot even see any green. Even at full scale, green areas are tiny
dots. The U.S. has long been way behind the curve on Internet speeds compared to
places like South Korea (N. Korea doesn't even have a word for Internet yet). If
you look at the advertised speeds map, most areas are advertising 6 MBPS or greater.
To get those speeds in most places you have to pay for a premium service. I pay
$52/mo. for 14 MBps (typically get about 13 MBps). That is the download speed. Upload
is for some reason pathetically slow. Even with premium service, my upload is about
500 kBps. Since I do a lot more uploading than most people because of publishing
AirplanesAndRockets.com (and a couple
other smaller ones for family members), the slowness is very noticeable. According
to a chart on
Gizmodo, Japan has the highest speeds (61 MBps), France is #5
at 18, Canada is #8 at 7.6, the U.S. is #15 at 4.8. Mexico and Greece appear to
still be on dialup.
