How Political Campaign Strategy Works #4

by Marshall Brain

An interesting look at the Dean/Obama 50-state strategy, where the candidate tries to win in all 50 states rather than focusing strictly on “swing states”:

The Dean Legacy

From the article:

Besides a desire to push the party away from a strictly swing-state mentality, Dean and Obama share a commitment to the nuts-and-bolts of grassroots organizing. On the stump Obama is quick to stress his roots as a community organizer and always thanks his precinct captains, who routinely introduce him at campaign events. “Change doesn’t happen from the top down. It happens from the bottom up,” he now says in his stump speech. Obama’s organizing has been greatly enhanced by new technologies like YouTube, Facebook and MySpace (Friendster had just arrived when Dean was running). “We pioneered it and Obama perfected it,” Trippi says. Obama embraced elements of the new politics, hiring the co-founder of Facebook, for example; but other efforts came from the grassroots–just as with the Dean campaign–as supporters organized themselves online and on the ground. The net effect is Obama’s large base of small donors, who are enthusiastic supporters he can tap again and again. Ninety percent of the $28 million he raised online in January, for example, came in donations of $100 or less. Obama has fused a tightknit group of advisers with a mass of ordinary people, creating what Trippi calls “command and control at the top while empowering the bottom to make a difference.”

How Kassam Rockets Work

by Marshall Brain

The Kassam rockets are flying again in Israel, and they are hitting targets and killing people:

IDF operations kill fifteen Palestinians since Wednesday

From the article:

The IDF struck back against Gaza’s Hamas leadership late Wednesday night, after an estimated 50 Kassam rockets and at least four Grad-style Katyusha missiles pummeled the western Negev and Ashkelon over the course of a few hours in the afternoon, killing a student at Sderot’s Sapir Academic College and sending dozens into shock.

This brings up the obvous question: Where does Hamas get the rockets? The answer: Kassam rockets are home made.

In America we have a certain mental image that appears whenever we hear the word “rocket.” We tend to think of something big, complex and expensive. We get that impression because we are used to seeing huge moon rockets or billion-dollar space shuttles flying precisely into orbit under the control of thousands of technicians.

The Palestinian Kassam rocket is just the opposite. It is small, simple and cheap. The idea is to create an easily manufactured, inexpensive terror weapon that one or two people can launch from almost anywhere.

How can Palestinians manufacture rockets in their basements? The key is to think small and to use everyday items wherever possible. Therefore, a Kassam rocket starts with a simple iron tube. In other words, you start with a piece of pipe. In a Kassam rocket, the pipe is usually about six feet long and six or seven inches in diameter. At one end of the piece of pipe you weld on four simple fins made of sheet metal. The sheet metal can come from anywhere - an old car fender will do.

Since this is a rocket, it needs some kind of rocket fuel inside the pipe. Palestinians use the simplest fuel possible. It is made of sugar and potassium nitrate, also known as saltpeter. The obvious question most people have is, “Sugar?” It turns out that sugar contains quite a lot of energy. You can see that energy when you are roasting marshmallows and one of them catches on fire. The problem is that sugar does not burn fast enough to use it as a rocket fuel. The potassium nitrate solves that problem by providing an oxidizer that accelerates the reaction. In the United States, there is a whole category of model rocketry called “Candy Rockets.” American hobbyists hold competitions to see who can create the highest-flying sugar-powered rockets. The Palestinians have simply taken the hobby to an extreme.

Once you have filled your pipe with its sugar fuel, you need a nozzle for your rocket engine. In a Kassam rocket the designers use a round metal plate with seven holes drilled in it. Each hole is about an inch in diameter, because that is about as big as a standard drill bit can get. This round plate then screws onto the bottom of the rocket.

At the other end of the rocket is a small bomb. A Kassam rocket has a payload of 10 to 20 pounds and the bomb is very simple. It is made of a metal casing filled with an explosive like TNT. The TNT is probably the hardest material for the Palestinians to obtain, so they smuggle it in or harvest it from old military hardware. The shell of a rifle bullet acts as a blasting cap to initiate the TNT explosion.

When you put this all together, what you have is a rocket that can lob a 10 to 20 pound bomb through the air for a distance of five or six miles. It is very much like an artillery shell, with the advantage that you do not need a massive artillery piece to launch it. Instead, you need a couple of simple guide rails to act as a launch pad. You set up the rails, lean the rocket against them, light the fuse and stand back. 30 seconds later a 20 pound bomb explodes five miles away. By the time Israelis can react, the people who ignited the rocket can be long gone from the launch site.

Because they have no guidance system of any kind, Kassam rockets do have their limits. There is no way to know precisely where the rocket will land. However, as a tool of terror, that randomness can make the rocket very effective. The Germans employed the same tactic with the V-1 and V-2 rockets that they sent toward London during World War II.

1) “The total number of people who play has declined or remained flat each year since 2000, dropping to about 26 million from 30 million”

2) “the number of people who play 25 times a year or more fell to 4.6 million in 2005 from 6.9 million in 2000″

3) “core players (those who golf eight or more times a year) has fallen, but more slowly: to 15 million in 2006 from 17.7 million in 2000″

4) about 25% of golfers are women

5) “Between 1990 and 2003, developers built more than 3,000 new golf courses in the United States, bringing the total to about 16,000.”

How antidepressant drugs don’t work

by Marshall Brain

It is startling to think that 40 million people are taking a drug meant to treat depression. That is a lot of depressed people. It is even more startling when you realize that the drug doesn’t do anything.

Prozac, used by 40m people, does not work say scientists

From the article:

The study examined all available data on the drugs, including results from clinical trials that the manufacturers chose not to publish at the time. The trials compared the effect on patients taking the drugs with those given a placebo or sugar pill.

When all the data was pulled together, it appeared that patients had improved - but those on placebo improved just as much as those on the drugs.

Also:

The pattern they saw from the trial results of fluoxetine (Prozac), paroxetine (Seroxat), venlafaxine (Effexor) and nefazodone (Serzone) was consistent. “Using complete data sets (including unpublished data) and a substantially larger data set of this type than has been previously reported, we find the overall effect of new-generation antidepressant medication is below recommended criteria for clinical significance,” they write.

So, what should you do if you are depressed? This article offers several possibilities:

Antidepressant drugs don’t work

From the article:

The treatments that do work

* Exercise: Helps some people with depression. Douglas Adams, author of The Hitchhiker’s Guide to the Galaxy, said running helped him cope with depression.

* Friends: Talking through your feelings can help in mild depression with a friend or relative or in a self-help group.

* Cognitive behavioural therapy: Teaches you to challenge negative thoughts and feelings of hopelessness.

* Interpersonal therapy: Focuses on relationships and problems such as difficulties with communication.

* Counselling: Helps you think about the problems in your life and find new ways of dealing with them.

How the Large Hadron Collider Works

by Marshall Brain

The Large Hadron Collider will answer some of the most basic questions about the universe:

At the Heart of All Matter

From the article:

Starting sometime in the coming months, two beams of particles will race in opposite directions around the tunnel, which forms an underground ring 17 miles in circumference. The particles will be guided by more than a thousand cylindrical, supercooled magnets, linked like sausages. At four locations the beams will converge, sending the particles crashing into each other at nearly the speed of light. If all goes right, matter will be transformed by the violent collisions into wads of energy, which will in turn condense back into various intriguing types of particles, some of them never seen before. That’s the essence of experimental particle physics: You smash stuff together and see what other stuff comes out.

See also:

This is an old article, but it lays out one of the types of experiments that might be done with the Large Hadron Collider:

Artificial black holes: on the threshold of new physics

From the article:

For several decades now, there has been a fundamental problem with modern physics. The problem is actually an embarrassment of riches: we have not one, but two systems that describe the universe remarkably well. One is quantum mechanics, which describes the rich and subtle behavior of waves and particles. The other system, general relativity combines space and time into one continuum, providing us with the best description of the movement of the planets and the expansion of the universe.

Scientists have realized that to truly understand the universe, we’ve got to make these two systems work together, even merge into a single, more accurate depiction of reality. But the two systems have not given up their independent identities easily. The challenge has been to find conditions in the universe where both the effects of quantum mechanics and general relativity are significant and measurable.

For this to be the case, you’ve got to pack a whole lot of mass (as general relativity mainly relates to gravity), into an extremely tiny volume (where quantum effects become important). Where do you think those conditions might exist? Fortunately, the universe has provided us with such a natural laboratory for fundamental physics: black holes.

The Large Hadron Collider will make it possible to create small black holes:

Amazingly, scientists are becoming increasingly confident that they will be able to create black holes on demand, in quantity, using the new atom-smashers due to come online in the next five years. Some estimates suggest that the new Large Hadron Collider (LHC) at the European Center for Nuclear Research (CERN -the acronym is in French) will be able to create an average of one black hole each second. LHC will bombard protons and antiprotons together with such a force that the collision will create temperatures and energy densities not seen since the first trillionth of a second after the Big Bang. This should be enough to pop off numerous tiny black holes, with masses of just a few hundred protons. Black holes of this size will evaporate almost instantly, their existence detectable only by dying bursts of Hawking radiation.

See also: A Giant Takes On Physics’ Biggest Questions

The day it turns on will be a moment of truth for Cern, which has spent 13 years building the collider, and for the world’s physicists, who have staked their credibility and their careers, not to mention all those billions of dollars, on the conviction that they are within touching distance of fundamental discoveries about the universe. If they fail to see something new, experts agree, it could be a long time, if ever, before giant particle accelerators are built on Earth again, ringing down the curtain on at least one aspect of the age-old quest to understand what the world is made of and how it works.

“If you see nothing,” said a Cern physicist, John Ellis, “in some sense then, we theorists have been talking rubbish for the last 35 years.”

Teens losing touch with common cultural and historical references - “Big Brother. McCarthyism. The patience of Job. Don’t count on your typical teenager to nod knowingly the next time you drop a reference to any of these. A study out today finds that about half of 17-year-olds can’t identify the books or historical events associated with them…”

Makes you think: Food or fuel?

by Marshall Brain

Food or fuel?

“As global starvation worsens, the U.S. plans to devote vast amounts of grain to producing ethanol.”

Ethanol fuels food price frenzy

“The amount of corn it takes to produce 75 litres of ethanol - roughly a tank of fuel - is enough corn to feed one person on a 2,000 calorie per day diet for a year.”

Bloomberg slams US energy law over corn ethanol

“A new U.S. energy law will cause an increase in global food prices and lead to starvation deaths worldwide because it continues to promote corn ethanol, New York Mayor Michael Bloomberg said on Monday.”

The end of Ulysses

by Marshall Brain

The Ulysses mission, launched in 1990, examined the sun by flying over its poles. You can learn more about the mission here:

Ulysses Spacecraft Flies Over Sun’s North Pole

Description of the mission:

But after 17 years, the power supply has decayed to the point where the spacecraft appears to be dead:

Ulysses to fall silent, its voyage to continue forever

According to the article:

Ulysses depends on radioisotope thermal generators (RTGs) for its power. The spacecraft is launched with a finite amount of radioactive fuel, the decay of which produces heat that the generator converts to electricity. From the moment that the RTG is installed, its power output begins to decay with the decay of its fuel. Now, 17 years after launch, the output of the generator has dropped to the point that Ulysses can no longer power all of its communications, heating, and scientific equipment simultaneously. It was in an effort to conserve power that the mission commanded the main transmitter to be turned off. Using the antenna only occasionally would have allowed ESA to prolong Ulysses’ life. Unfortunately, something bad happened in the power systems when the transmitter was switched off…

This video shows the launch the the Ulysses spacecraft in 1990 on STS-36:

Eventually Ulysses should loop past Jupiter and exit the solar system.

How Freeconomics Work

by Marshall Brain

An interesting article about the rise of free products and services (freeconomics):

Free! Why $0.00 Is the Future of Business

From the article:

Once a marketing gimmick, free has emerged as a full-fledged economy. Offering free music proved successful for Radiohead, Trent Reznor of Nine Inch Nails, and a swarm of other bands on MySpace that grasped the audience-building merits of zero. The fastest-growing parts of the gaming industry are ad-supported casual games online and free-to-try massively multiplayer online games. Virtually everything Google does is free to consumers, from Gmail to Picasa to GOOG-411.

The rise of “freeconomics” is being driven by the underlying technologies that power the Web. Just as Moore’s law dictates that a unit of processing power halves in price every 18 months, the price of bandwidth and storage is dropping even faster. Which is to say, the trend lines that determine the cost of doing business online all point the same way: to zero…
