Riding in Cars with Boys

Michael — Sun, 23 May 2010 02:43:00 +0000

This conversation took place while driving three ten year-old boys who are unapologetic geeks to the movies.

Noah: I'm telekinetic
Me: Oh really? Well if you're telekinetic raise my hand.
pause
Me: But I really am telekinetic.
Boy1: Oh Yeah, prove it.
Me: I can make everybody in this car suddenly lurch forward.
At this point I was coming to a stop anyway so I hit the brakes a little harder that I normally would have.
Noah, Boy1 and Boy2: (in unison) That's not telekinetic. That's just kinetic.

Your Inner Fish

Michael — Mon, 19 Apr 2010 21:01:00 +0000

At the recommendation of Teacherninja I recently read Your Inner Fish by Neil Shubin. Thanks for the recommendation. I really enjoyed it.
Shubin is a paleontologist and it was his research that discovered Tiktalik, a fossil animal that was almost exactly what was predicted to have existed halfway between fish and land animals. Much of the book describes that expedition and the others that lead up to it.
The book does not stop at just Tiktalik. He builds on the similarities and spends a great deal of time showing how so much of biology is based on remarkably similar structures. He show how early in the development of nearly every embryo, chicken, fish, squirrel or human the same organs form from the same rows of cells in each species even though they may have drastically different uses in the final creature. I found these chapters very fascinating.
Shubin avoids pretty much entirely that political debate that is currently going on about teaching evolution in schools. I guess from his perspective evolution via natural selection is such an established fact he felt no need to defend it. I agree with this position. It was a science book and I don’t fault him for setting all politics aside and just speaking to the science. I would like to point out that Shubin’s discovery of Tiktalik was predicted by evolution and that Tiktalik made his appearance during the middle of the Dover school board’s attack on teaching evolution in school. I’m sure Shubin didn’t plan it this way, but at the same time the Dover school board had “experts” testifying that no transitional fossils had ever been found, Shubin was uncovering yet another transitional fossil.
I listened to this book on CD while working. I plan on going back and reading it for real when I get a chance. Some of the details in the middle of the book deserve more attention than I could give them just listening while working.

Sibling Solidarity

Michael — Thu, 25 Mar 2010 12:37:00 +0000

(This is another personal post that will likely upset some readers.)

I love my kids. Sure they can frustrate the hell out of me sometimes but I still love them. I didn’t enjoy being a teenager and I can tell that my two teenagers aren’t exactly digging it either. It seems that most of their troubles come from peer pressure; so-called friends attacking them, frequently physically, for their opinions and beliefs and trying to get them to just go along with the crowd. What’s really upsetting to them is that most of this criticism comes from people whom they think should know better, members of our church. As a parent few thing make me more proud than when one kid stands up for the other, especially in a situation where they really don’t have anything to gain my doing it. We had just such a situation last night. And although it was very traumatic for her, I couldn’t have been more proud of my oldest daughter.
A little back history: Aaron hasn’t been attending church at our ward for the better part of a year now. He has been arranging, on his own, to get rides back and forth from the Brocket Ward. He gets along with the kids in that ward better, they accept him and genuinely love him. In stark contrast, the kids in our ward tease him, call him a Satanist and frequently physically assault him. In his own words it is rather ironic that the least spiritual hours of his week are spent at church. He doesn’t participate in the Varsity scout program on Wednesday night. We’ve moved him to another troop that is a real community troop where sharing the same religious upbringing is not a requirement to hold positions. He gets along much better with these guys. On Wednesday he even arranges for rides over to Brockett to hang out with the kids from that ward that he gets along with so well. In the entire time that he has been attending that Ward only one person from our ward has asked about Aaron. He was genuinely concerned and I thanked him for caring and not forgetting about him. Not a single other person has given us the slightest clue that they’ve even noticed his absence. In stark contrast, the leaders from Brockett comment to us about how they enjoy having him there and miss him when he’s gone.
Well last night I dropped Rachel off at the church for her Young Women’s activity. She typically doesn’t have the same issues as Aaron so I was a little surprised when Victoria brought her home and she was in tears. I asked her what was wrong. Rachel then proceeded to ask if she too could attend Brockett Ward rather than our ward. Apparently even in his absence Aaron is still a topic of conversation. A few of the kids were making fun of him and it really upset Rachel. I found a bit odd that their primary criticism of Aaron is that he “believes in evolution”. Rachel has never been one to gossip and hence she refused to tell me which kids were involved. But she did say that it really surprised her because she had though that these kids were above that. Apparently she had spent half of the meeting outside crying and just waiting for us to come pick her up.
Rachel didn’t openly defy these kids, that’s just not her style, but she did refuse to be a part of what they were doing. They still fight like, well brothers and sisters, but when the chips are down it’s really nice to see them standing up for what they know is right. Rachel didn’t want to tell anybody, especially Aaron, about what happened. I thought that he needed to hear it. After he was dropped off from his activity at Brockett we talked about it and he gave his little sister a nice big hug.

I chose to post this in order to add my name to Rachel’s. I stand behind my family. You criticize one of us you criticize us all. And we won’t tolerate it.

As far as the chief complaint lobbied again Aaron goes, Evolution is a fact. Get used to it. It used to be a theory but it has long ago graduated to a fact as far as I am concerned. I would even go so far as to say that evolution is more of a fact than gravity. Gravity is still lacking a clear definition of how it works. Like evolution gravity has been tested and tested and tested thousands of times but gravity is still lacking a carrier. We don’t quite know how it works. We have hypothesized the existence of the graviton, but haven’t actually seen one. In contrast we have found DNA and natural selection, the elements that make evolution work. So in a very real sense there is more evidence supporting evolution than gravity. In the past when people have asked me if I “believe” evolution I’ve had to rephrase their question in my answer. Because belief requires faith I don’t think it applies to evolution. Faith is a belief without evidence or even in spite of the evidence. You just aren’t looking if you don’t see evidence of evolution. So I respond something like this, “I accept the overwhelming evidence that life evolved via natural selection.”

"If science proves some belief of Buddhism wrong, then Buddhism will have to change. In my view, science and Buddhism share a search for the truth and for understanding reality." The Dalai Lama
Wise words. It's a shame more people don't apply this same idea to thier own beliefs. I'm glad my kids are.

Let the Robots Do It

Michael — Tue, 02 Feb 2010 11:59:00 +0000

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.

This is a very well done video that explains the basics of skepticism. Thanks to teacherninja for point this out to me.

Emotional Awareness

Michael — Thu, 17 Dec 2009 15:07:00 +0000

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.

Lie To Me

Michael — Mon, 23 Nov 2009 17:27:00 +0000

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.
