Mr. White also wrote many outstanding essays.
In his 1948 Here Is New York,
he extols the city's resilience and eerily
predicts what a few airplanes could do to it.
Thanks for the clarification! I scoured the web for the real journal article but didn't find it. I did find an abstract for one of the 1993 papers you mentioned, so I wondered about the mass discrepancy. Better luck helping reporters get it straight in the future. Take their presence as a sign that your work is interesting to lay people.
Horrifying monsters? I'd be plenty worried if I saw Ed Harris in a dark suit following me around campus! Especially if he urged me to get back to work!
Diskettes transmit too much IR and provide an inferior image, according to this
Sky and Telescopearticle
by Ralph Chou,
a professor of optometry.
Don't fool around, get a #14 shade from a welding supply shop. They're cheap, convenient, and reliable. Mine is a 4x5-inch plate of black ceramic material that turns the Sun a lime green color. When I bought it, the guys at the shop said, "Yeah, we got a few of those left over from the last eclipse. Nobody uses 'em for welding, they're too dark!"
In 1994 I happened to encounter a group of school children during a partial eclipse. The clouds parted, and on cue from their teacher, all of them whipped out little pinhole cameras they had made from sheets of paper! Now that was a sight I won't forget.
The spiral staircase in Jerome's and Vincent's house is my favorite symbol in all cinema.
As the staircase separates the upper and lower floors of the house, the DNA molecule divides society into valid and invalid classes.
Vincent endures a rigorous daily routine to keep his place in this society despite his imperfect genes,
and in one scene, Jerome heroically struggles to climb the staircase despite his physical disability.
I believe peer pressure is the most effective way to improve code readability within a programming team. Coding standards can only address low-level issues, and only if they are enforced. Regular peer review focuses everyone's attention on true readability issues. A senior programmer can learn a lot from a junior programmer this way.
The best way to ensure readability is to test readability.
Show your code to two other programmers; whenever they have a question, revise the code to include the answer.
After you make this a regular practice, you may find yourself anticipating reviewer comments as you code.
Then you will understand readability in a way that no lone-wolf pundit possibly can.
I am a violinist. For a few bucks you can get a low-tech device called a practice mute.
It's a heavy block of brass that fits atop the bridge and cuts the sound output by 20 dB, and it gives you exactly the tactile feedback of your favorite bow. The professor's invention probably falls far short on special articulation of individual notes.
For varying tone on time scales of a few bars, though, it could improve on the results of a typical MIDI sequence.
The dark corner of many HST images is an artifact of the Wide Field and Planetary Camera (WFPC).
Here's an
illustrated explanation. The recent service mission replaced it with the Advanced Camera for Surveys (ACS), which is bigger, more sensitive, and makes nice square images.
I've looked at several nebulas and galaxies
through telescopes, and yes, they are all
basically grey.
I think there is value in enhancing even a
visible-light image to highlight important
structural details.
For example, in the mostly green
Hubble
PR image of the Eagle Nebula, they assigned
the orange hydrogen-alpha emission line to the
green channel so it would be easier to
distinguish from the red sulfur ion emission
line.
Since
conventional images of this nebula are typically orange,
I wondered what the color mapping was.
I agree that they should generally do a better
job of explaining it, but I don't mind that they
did it. Through a telescope I can't see the nebula at all, only the star cluster.
I think the greenhouse effect has more to do
with absorption than with angle of incidence.
Blackbody emission peak wavelength decreases with temperature.
The Sun, a 6000 K blackbody, emits visible light,
which passes through the windows and is absorbed
by the interior.
The interior, a 300 K blackbody, emits infrared,
which is absorbed by the windows.
In his autobiography, 19th century instrument
maker
John
A. Brashear describes a project to make
lenses out of salt crystals for an astronomer
who wanted to make infrared observations.
Salt is supposed to be much more transparent
than glass in that band of the spectrum.
Once upon a time, I evaluated some software
under a similar plan. I naively put my real
phone number on the registration form. A
salesman called me and asked a few questions.
I answered them but asked him to call my boss
instead because I had no authority to make
purchasing decisions.
He called me back a few weeks later to find out
if we were going to purchase. I reminded him
to ask my boss.
A year later the same guy called me again,
and I asked him to put me on the "no call" list.
When he failed to understand this, I got angry.
This exchange guaranteed, first, that I would not
recommend his company's product to my boss,
and second, that I would never give my real
phone number for any other evaluation
license.
Note to Battle Creek city managers: hire competent IT professionals, and this won't happen.
Sensible enough, but when I worked in BC,
we had a heck of a time finding people.
The few that we found either relocated
or commuted more than an hour each way.
Apparently it's not an IT talent rich area.
did anyone see anything as remotely beautiful as what is in this article?
What I saw around 11pm EST from SE Michigan looked like the title image but fainter; vertical streaks of pale green filled half the sky, converging just south of the zenith. At midnight the display was smaller, smoother, and red. At 1am there was a low band of green.
For our next big event, on signal,
lets all simultaneously:
2) pick up a telephone handset -
January 1, 2000, 12:01 AM
5) withdraw funds from the bank -
December 31, 1999, 11:30 PM
6) visit the same web site -
February 7, 2000,
18:30 GMT,
yahoo.com
Now can we knock down 1) 3) 4)
in another 2-month period?
Here are the
articles
the popular press cited
(very awkward registration required).
The "news and views" piece explains that
astronomers previously thought the galactic core
might be as much as 1500 times as wide
as the event horizon of an equally massive
black hole.
The new observation indicates that it's
no more than 20 times as wide.

Did the archaeologists find a large black monolith among all the little stone fragments?

Since I'm a little rusty, I dug up some articles about type I and II supernovae, and white dwarves and the Chandrasekhar limit. I also found a stellar who's who which says HR 8210 is IK Pegasi, at RA 21h26m Dec +19.3. My Sky Atlas 2000.0 shows a 6th-magnitude star there, but it's not marked.

Here is an abridged online version of Science Made Stupid. My favorite is the constellation chart.

I used to have a recording of a Pharmacia chemist singing it with his barbershop quartet, but someone stole it and left 4 other CDs behind. Go figure.

NGC 1068 is also known as M 77. It's one of the nearest galaxies to us. You can see it faintly in 7x50 binoculars if you look in the right place.
If you're going to have industrial pollution, that's the kind to have. My favorite was Froot Loop day.

Ever since I read about the play-by-email C++Robots I wondered where I could find the original concept. Thanks!
