Let the Robots Do It

Posted by on Feb 2, 2010 in astronomy, critical thinking, politics, science | Comments Off

I am a space nut. As a kid I built models of the Apollo lunar landers. I was too young to remember the Apollo project first hand, but I do remember Skylab and the Apollo/Soyux missions. I even got permission from my folks to skip school and watch the first shuttle launch and landing. I also remember quite vividly the first pictures sent back from the surface of Mars by the Viking lander. I remember thinking how lucky I was to grow up in a time when the Voyager’s grand tour was even possible. I watched the first raw image returns from the Cassini missions live as they came in from Saturn in 2004. Every day I check multiple Astronomy websites and I make a conscious point to look up in the mornings as I walk to the car and see if I can locate the planets that are currently visible.

So with this introduction you might find it odd that I applaud the announcement to all but kill NASA’s manned space flight program. I don’t have a problem with manned space flight in particular. We just need to look at it honestly and objectively and see what kind of return on our investment we’ve gotten on manned space flight when compared to robotic missions.

While Voyager was taking pictures of Jupiter and all its moons Apollo Soyux was just trying to see if we could get Russians and American’s to shake hands. While Cassini Huygens was taking the best shots of Saturn ever manned missions were trying to figure out how to not burn up another shuttle during re-entry. While Mars Pathfinder more than doubles its life expectancy and continues to send back data from Mars manned missions are trying to figure out how to rescue a shuttle if tiles get damaged on the shuttle. While Hubble continues each day to amaze us with images from the extremes of the universe the ISS is trying to figure out how astronauts can process their own urine and re-drink it. I could go on and on with these examples but my only point is that while the robots are doing real research and doing a bang up job in the process the manned missions are quite literally doing little more than trying to figure out how to stay alive.

I’m not denying the political chest thumping advantage of being able to say we are the only country that has ever set foot on the moon. But let’s not deny that that’s all that it really was. The science was at best and afterthought. We only actually put one scientist up there and he was bumped up to an earlier mission when we realized that we were going to be discontinuing the program. If we feel we need to thump our chest again to show how great America is let’s do it after we’ve taken care of some issues much closer to home. But let’s just not disguise it as a scientific pursuit.

A few years ago when Constellation and Orion were announced I was more than a little annoyed. Why were we spending so much money to rebuild 70’s era technology to do something that we’d already done? So I’m actually glad that the current budget is choosing to cut it. Let Richard Branson, Burt Rutan and the rest of the private sector spend their own money to figure out how to make a toilet that functions in zero-G. Let’s invest our tax dollars into something based on science and with a cost effective return on our tax investment. The robots have proven that they can do that exponentially better than any manned mission. Read More

Emotional Awareness

Posted by on Dec 17, 2009 in books, Buddhism, emotions, introspection, science | Comments Off


I have long been a fan of the Dalai Lama. Even though I don’t accept the deeper doctrines of Buddhism, like karma and reincarnation, I really admire the efforts that he has put in to teaching people to live more peaceably with each other. His optimism is infectious. I’ve also been a fan of the work of Dr. Paul Ekman. So it has been really enjoyable to have my commutes filled with their voices as I’ve been listening to Emotional Awareness: Overcoming the Obstacles to Psychological Balance and Compassion: A Conversation Between the Dalai Lama and Paul Ekman.
Ekman and the Dalai Lama both have the same goals but they are approaching them from different perspectives. Ekman is the scientist who is studying emotion scientifically with the goal of trying to make people’s lives better. The Dalai Lama is a spiritual leader who is also trying to make people’s lives better. Both have found a very common ground in the study of emotion and how to respond to our emotions.
I have so many things to take away from this book that I don’t really know where to start.
Much of the conversation focuses on just being aware of our own emotions and controlling what we feel and how we respond to that emotion. The Buddhist principles of compassion and mindfulness come into play quite a bit in this area.
Ekman refuses to classify emotions as positive or negative. It is only our response to that emotion that can receive such a value judgment. Fear that prompts us to get out of the way of an oncoming train can be good. But fear used to intimidate is bad. Similarly pride and anger can also have similar positive effects if channeled constructively. The only emotion that both the Dalai Lama and Ekman agree has no positive effects is contempt.
Moods are a different issue and both men agree. Moods poison the well and last longer than emotion. Most emotions only last for a relatively short time. Moods however skew you perception and are never constructive. A cranky mood will cause you to misinterpret the actions of others to fit your preconceptions. Even a good mood can be destructive if it causes you to gloss over and not give due attention to a stimulus. I found it very interesting that The Dalai Lama agreed that being overly optimistic can have similar negative effects to being overly pessimistic.
The biggest take away I have found from this book is simply an awareness. I’ve been trying to identify my feelings as emotions or as moods and then trying to consciously decide how to respond. I have a bad habit of taking tidbits that I’ve learned and educating my family. That I believe is good but I tend to sound like I’m lecturing them. I hope that as I learn better emotional awareness I will also become better at sharing with my family. Read More

Lie To Me

Posted by on Nov 23, 2009 in science, skepticism, TV | Comments Off

So I’m typically well behind the curve when it comes to television I simply don’t watch enough to stay up to date. I typically prefer reading over TV hands down. On the rare occasion that I get some free time that I want to blow in front of the tube I am reminded of the Bruce Springsteen song “57 Channels and Nothing On.” Being so colossally underwhelmed by what I’ve found on TV hasn’t really inspired me to give it much of a second chance.
At my lovely bride’s behest I sat down and watched a couple episodes of Lie To Me. I have always been a fan of the work of Dr. Paul Ekman. I think his analysis of facial expressions and human emotion is absolutely amazing. Years ago I read his book Emotions Revealed. I found the universal nature of human expression to be highly fascinating. I didn’t realize it at the time but the lead character in Lie To Me was deliberately modeled after Ekman. In fact, the entire premise of the show revolves around Ekman’s research.
The characters and story are, of course, fictionalized but I think this is a very effective way to put real science out in front of a popular audience. In the few episodes I’ve seen I’ve found the characters to be very deep and relatable. Without this any story would get boring quickly no matter how accurate the science. I’ve blogged before about how real science is truly marketable and how irritated I get when bad science is used as a lazy excuse to tell a story. I’ve truly been impressed with how this series has stuck to real science to tell their story in a very entertaining way. Read More

Junk Science

Posted by on Nov 12, 2009 in books, critical thinking, science, skepticism | Comments Off

I think science is very cool. I’m not talking about technology or any of the applications of what science has discovered. Sure airplanes are cool. MRI machines are cool and on and on, but what I’m talking about is the process of science. I’m fascinated by the fact that human beings have developed a process that we can learn test and get answers to things that we didn’t understand before we started.
I reject the popular concept of scientists as just a bunch of know-it -alls sitting around gloating about everything that they already know. As Tyson said in my post the other day, “If you aren’t at the drawing board every day you aren’t in the game!” Science isn’t the list of facts that we collect it’s the process for learning those facts.
In Junk Science: How Politicians, Corporations, and Other Hucksters Betray Us By Dan Agin Ph. D., Agin shows many of the ways that science gets perverted by politicians, the media, religious leaders and the scientists themselves. The book is very thorough and covers many of the recent popular scientific discoveries and media controversies. Agin gives his take on what real science is behind the discoveries and then explains where and when those involved went from real science to bad science and then to junk science.
He make clear distinctions too. In order for it to be called real science it has to follow all of the rules. It puts away presuppositions, uses strict controls to avoid unintentionally biasing the results, is open and encourages others to duplicate their process and find any mistakes, and many other things. Bad science is frequently just when some of those protocols and procedures get sloppy. If the input gets sloppy the output can no longer be trusted.
Most of the book focused on the last category, junk science. All too frequently people with agendas other than honest discovery use a process that some observers mistake for science. My daughter gets a kick out of these so-called Ghost Hunters who walk around with insterments they don't really know how to use and then when something, anything happens that they don't understand they call it, "something significant". Sometimes these people have financial motives for going to the dark side(Andrew Wakefield and the Anti-vaccination movement) sometimes religious motives (Michael Behe and the Discovery Institiute) and frequently political motives (the Global Warming denialists). But regardless of their motives they all too frequently start with their conclusion and then look for evidence to prove it. This is backwards. With this attitude they are no longer doing science. They are doing junk science.
Again believes as I do that science deserves more respect than it gets in the public perception. I worry that in many ways we are going backwards. We are allowing religion and politics to define and even to trump science. I think that all three can have a place in a civilized society. I have no problem with a civilized debate on how to respond to a scientific discovery. But let’s not corrupt the science or deny it just because it may not be morally or politically what we’d like to do.
Science is just now starting to understand some processes that may have profound impacts on humanity. Stem cell research, for instance. Now I understand many of the ethic and moral concerns that have been raised by those opposing it. I agree that this should be the subject of vigorous debate. But leave the science alone. It stands outside the debate and should not be a part of it. Years ago doctors discovered a link to testosterone and hair loss. Identical twins where one had been castrated and the other had not the intact twin lost his hair and the castrated twin did not. Now is anybody recommending castration as a way to stop hair loss? Not that I’m aware of. You see in that case we had the science and we understood it. But we simply chose not to act upon it for social, political, or ethical reasons. But the science was not corrupted to make the arguments. In my opinion we need to have similar respect for the science behind many of the issues that are happening today. We can’t even begin to have a decent political discussion on global warming because so much effort is being spent on denying the science. The same goes for stem cells and several other top hot button issues. Let’s take the first step and accept the science as valid. Then we can have an honest discussion about how to react to the discoveries or even if we need to react at all.
It took me a while to get through this book, primarily because it is so thorough. I have no criticism at all of his points or his logic. If you’d like to read more on this subject I’d recommend reading Voodoo Science by Robert Park first. It isn’t quite as though but it’s easier to read and covers many of the same themes. Then come back and read Junk Science. Read More
