Inventions as Nobel Prizes.
The inventions winners are (and this is my own editing to make it more understandable)
1909, Guglielmo Marconi and Karl Ferdinand Braun, Wireless Telegraphy
1912, Nils Gustaf Dalen, automatic gas regulators for lighthouses and buoys.
2000, Zhores I. Alferov and Herbert Kroemer, Diode laser (used in fiberoptic communications, laser scanners of all kinds, and CD, DVD, and blueray players)
Jack S. Kilby, Integrated Circuit
2009, Charles K. Kao, Fiber Optics
Willard S. Boyle and George E. Smith, CCD imaging device (used in digital cameras)
According to Kroemer in a colloquium I attended years ago, the 88 year break was something of a backlash to Dalen's prize. (The following is my explanation, not Kroemer's.) While the gas regulators were a tremendous boon to shipping on the rocky shores of Scandanavia, they were basically an engineering feat not a unique new application of physics for a revolutionary device. Many felt that choice had lessened the value of the prize so inventions were passed over for many decades.
Personally, I'm glad to see that inventions are back, that they are being chosen with care, but are in fact excellent examples of putting basic physics to practical use.

Sail Journey
Natalie's friend Mezzie Montooth was kind enough to come with me, and even though it was her first sailing experience she was the best trooper I've had yet.
The day started out beautiful and as we cruised through San Pedro Harbor (where the oil islands are) I thought it was a perfect day for the assault. The breeze was steady but not too strong and in a good direction. I made it past the Long Beach entrance to the harbors and past most of Long Beach Harbor without incident.
Unfortunately, as we tried to make it past the Los Angeles entrance and the waves got choppy and the wind picked up. There were even white caps on the waves which is the first sign that it may be too windy for a small boat like mine. Then a wave and a wind shift made me accidentally TACK and I decided to sail more conservatively. Unfortunately, that made it even harder to make progress into the wind. Meanwhile, poor Mezzie was being sprayed by each wave we went over, was soaked to the bone and starting to get cold.
So I finally made the right decision and turned around. Even that was tricky though. As I came about the mainsheet got tangled and nearly tipped the boat. Still we managed to get it righted with out tipping. We did start taking water over the rail though so it was the closest I have come in this boat yet.
Sailing with the wind was much easier and we quickly made it back into calmer waters. Unfortunately, as I docked, my tiller broke so I don't know how I will deal with that.
When I finally looked it up on a map I wanted to cry. We had probably made it more than 90% of the way, and if I had known just how close we were I might have pressed on, but I think it was the right decision anyway. (I tried to get a map of the trip on google maps or mapquest, but haven't figured out how to get a full picture of it saved so I can post it here.)
Once I get the tiller fixed I think I'll stay inside the bay for the rest of the Fall and Winter and try another assault on San Pedro in the Spring. It was certainly the longest and best sail I've had in my Dinghy yet, and was a lot of fun. Thanks again Mezzie, that sail rocked.

On Movies and Scripts
- A good movie really depends on a good script.
- When movies add or toss things to get a certain rating it really degrades the movie.
The movies I've seen or completed recently include
- Harry Potter and the Half Blood Prince
- Transformers
- Holes
- G.I. Joe
- On Her Majesty's Secret Service
One might expect G.I. Joe and Transformers to be similarly good or bad movies. Both a near future sci-fi action flicks that strain credulity, but whereas the script for Transformers was painfully bad, the script for G.I. Joe was surprisingly tight and well crafted. The action moved neatly, the humor was silly but enjoyable, the storyline was good and managed to both tie up the action neatly and set the stage for a sequel. Quite honestly it was probably the best movie in that genre I've seen in a long time.
Holes and On Her Majesty's Secret Service also illustrate the power of a good script. OHMSS was about as low on techno-gadgets and action as any Bond movie I've seen. (It is unique in many ways such as being the only one with George Lazenby, one of very few where Bond falls in love (gets married even) and in spite of the name, most of the action is renegade work done outside of official business.) But I thought the coherence and overall flow were great. (And I know everybody says Pussy Galore is the best Bond-girl, but Tracy Bond would drive all over her a--. I've found my favorite Bond Girl.)
Holes is one of the best triumphs of script and old fashioned good cinematography over spectacle. The movies weaves together about 4 improbable, almost silly and boring, stories into a single tapestry until they all tie together in the end. The peaks of action are digging holes, eating onions, and mending a leaking roof. But the whole is very delightful. (And unlike a spectacle movie it held up very well to the fact that I began watching it while substitute teaching nearly 18 months ago.)
The last thing I wanted to talk about was when they seem to be blindly seeking a rating. The Half-Blood Prince is one of my favorite Harry Potter books, and I think probably the most terrifying. By rights it probably should have become a PG-13 book. (I've always figured the books are targeted at Harry's age so this one should be for 16 year olds.) But they seemed to tone it down, possibly to maintain the PG rating. Dumbledore's terrors in the cave and his blood curdling "fear" near the end both came across much less intense than in the book, and the battle of Hogwarts was almost completely eliminated.
By contrast Transformers threw in a lot of pointless dirty humor and bad words for no aparent reason other than to get a PG-13 rating. Sure the blonde moved the story forward, but Mom on "minty" brownies spilling all of her son's private business was just crude.
Anyway, if you want my ratings of the movies
Holes was excellent and probably the strongest of them all. 4 1/2 stars.
GI Joe: Well above my expectations 4 stars
Half-Blood Prince: Very exciting, but like most of the Harry Potter films it is to the books as campbells chicken noodle soup is to chicken caserole. The flavor is similar but it really only hints at the notion that there are chicken and noodles there. From book 3 on the films haven't done the plots of the book justice. 3 stars
OHMSS: One of my favorite Bond films yet, but I tend to like that which is different. 3 1/2 stars.
Transformers: Well if you get to stare at Megan Fox and watch giant robots fight, how bad can it really be. (Because that is exactly how bad this is.) 1 1/2 stars.

Fishing With Perry
Here you can see him showing off his catch. Looks pretty good doesn't it.

Renewing an Old Hobby
So finally this week I decided to take some of my birthday money and get back into leatherwork. The local Tandy Leathercraft store was kind enough to give me wholesale price both for it being my birthday and Perry being a scout. I bought a cell phone case (my cell phone always gets beat up in my pocket with my keys), a belt blank, a belt pattern, and a buckle.
Here is the belt blank after the pattern has been traced and cut in but none of the tooling has been done.

Misleading Statistics, Again
But if you notice the cost per mile trends downward as you get to higher and higher mileage. In fact if you plot the total cost to drive 10,000 miles, 15,000 miles and 20,000 miles, you find that the slope (the actual cost of driving each mile) is nearly linear. They have included the base cost of owning, insuring, and maintaining the car into the cost per mile. In fact the cost per mile is only about 16 cents per mile.
So why does this matter? You do have those ownership costs! Well of course you do, but very few of us are really going to totally get rid of the car. So in figuring the cost of driving verses public transit we want to know how much extra each mile is going to cost us. That's 16 cents for a small car (I'm guessing about 9-11 of those are for gas, the rest for maintenence.)
In my case, driving to work each day (instead of once a week and staying here) would add about 1200 miles per month. At 35.4 cents/mile that is $425, and it would be reasonable to pay up to that much for a place to stay up here, but at 15.8 cents per mile it is only $190. There are of course intangibles both ways. (Sleeping next to my wife, seeing my family, verses the wear and tear on me.), but it is a very different picture.
I just hate when the stats are misleading like that. I'm no fan of long commutes or excess driving, but let's not claim that simply not driving is going to save you $400 when half of that is just in the cost of owning the car.

Sailing Adventure II
Perry at the Helm!! His ability to steer came in quite handy on the return trip. There was a time when we needed to Gybe the spinnaker. A challenging task even with many hands so both Andy and I had to be on the sheets and sails. Luckily, Perry was there to be the skipper. (I was actually more terrified in this picture though because Perry is sitting there steering a $100,000 boat in a narrow channel with other boats around.)
There is a boat that will take you ashore, but it costs $3.50 per person. That's not bad, but it adds up quick so I thought Perry and I could save a bit by going ashore in Andy's little dinghy. It worked well, but unfortunately the blade of one of the paddles came off and sank before Perry could grab it so I had to break down and pay for us to go back to the boat.
I had also brought dinner to cook aboard, but Andy's wife Katie was so sick and desperate to get off the boat that we ate on land instead. Andy treated us all and I gave him the lasagne I had brought in return.

Sailing Adventure
It was actually part of an 11 race series including 5 races to the island, 5 races back, and one race there, around the island, and back. The short version of the story is that outside of sex, this was probably the most fun I've had in the last 20 years.
Gone Walkabout
Next I passed some cows luxuriating in the shade.
It's easy to forget how close to the urban environment we are sometimes. But the apartments in the background are a quick reminder.
Assymetry
If you can't tell, both English and Spanish start by saying "Please Keep the Restroom Clean." Both end with "Thank You", but the Spanish adds a the extra line, "Don't throw paper on the floor." And I keep asking myself, is that cultural, racist, or what gives?

Tax Season
You see I was laid off in February of last year and spent the remainder of the year either underemployed or over/underemployed. (I'll explain that in a moment.)
I was lucky enough to have a solid second job at the time and I quickly managed to get on substitute teaching lists for both Long Beach Unified School District and Kelly Educational Services. This kept me busy and kept the morgage paid (though little else). With the help of family, tax returns, some severance pay, government, savings, and prayer we managed to make it through spring.
By summer I picked up a second part time teaching job and by Fall I had three. This is what I called over/underemployed. I had the teaching load of 2 full time instructors but was not full time anywhere. Still, I could finally feel self sufficient again.
So anyway, it came tax time and I was grateful to find that while I did in fact have six or seven W-2s the total was well over $2000 so I guess I can feel confident in my worth as a father and husband.
Staci took me to her accountant to do the taxes. I've always done mine myself, but I have to admit this was more enjoyable. In part because someone else was doing the nitty gritty and in part because he was really a delightful guy to hold a conversation with. Our supposed hour and a half appointment lasted nearly 3 and poor Natalie and Richard got stuck with our kids, but they were very sweet about it.
Oh, by the way, after one full year of scraping for whatever jobs I could find. I do once again have a full time position. In fact it is my first tenure track job. I am now the newest Physics Professor at Pierce College a part of the Los Angeles Community College District. I have actually wanted to teach here for a long time as they are working very hard to implement the best practices of physics teaching. On the other hand, when I was working several part time jobs I could justify doing a good enough job, now I truly need to do an excellent job. When you combine that with the fact that it is a new teaching style, the administrative and committee responsibilities, and the fact that it is on the far side of Los Angeles County I am still working my tail off. I finally rented a room over there because the commute home each night was too hard and I was in after everyone was asleep and out before they woke anyway.
Still I am excited and very blessed. I am grateful to family and friends and a wonderful wife who helped me pull through a challenging year. I am grateful that we live in a country that helps those who are struggling and hard work is still rewarded. And I am grateful to the Lord for his tender mercies.

All Alcohol Must Be Radioactive
Now purefication is good enough that you couldn't tell from chemical analysis, but fresh (as in less than a few thousand years old) plant matter has significant amounts of Carbon-14 in it which is radioactive. By contrast, fossile fuels are millions of years old and all of the carbon-14 has decayed out. So if your alcohol is radioactive, it is made from grains and fruits, if it is not it is made from petroleum.
Just one of the many facts I learned in "Physics for Future Presidents" which I'll review soon.

How many blades
I never was much of one to go in for these fancy things figuring 2 blades were probably enough. But lo and behold here I am a convert to that ridiculous fusion mostly because of excellent marketing.
You see, I bought a reusable gillet sensor razor my first year back from my mission hoping that if I kept a closer shave my girlfriend would want to kiss me more often. (That soooooooo was not the problem.) I kept it for well over a decade (still have it in fact) and I would probably still be using it except for that excellent marketing.
You see I never bought the fusion razor. They sent me that for free in the mail. That is no small gift to get for free in the mail as they retail for nearly $10 (I'm sure wholesale is much less.) So now I could try it, FOR FREE. And I'll be darned if 5 blades aren't more comfortable than 3. So now while I will still use cheap disposables if that is what someone has or someone buys for me, I really like the gillete fusion. (And they do stick it to you on cartridges).
So the real question is, at what point does more blades become counterproductive. SNL (I think though it could have been MadTV) did a skit on a 15 bladed razor. I thought 4 was ridiculous, but I love 5. Where does it really end.
(On a side note, I shaved today with a single blade razor. I thought it had gone reasonably well if slightly less comfortable. Then I turned around and noticed about 50 tiny dots of blode coming from my neck. So maybe it is more than just minimal comfort.)

What A President Should Know (Book Review)

Foolish Adventures
The winds inside alamitos bay were pretty light, but they were pointed such that I made a fairly quick clear shot out the jetty to San Pedro Bay (That's the ocean area off of Long Beach and inside the breakwater. At least that's what google maps calls it.)
In just about two hours I managed to sail all the way across the open bay area to Long Beach Harbor. I pushed it a bit farther than I normally would have because I wanted to say I had crossed out of Long Beach Harbor into Los Angeles Harbor, but I didn't make it that far. I didn't know where the division was and it would have been too far anyway. I think in the future I'll avoid that area. I got honked at by two giant boats (one was pushing a barge that carried a mack truck with its own sizeable parking lot and the other was a huge (several hundred yards long) cargo ship.) I was never in eminent danger, but I did need to change course to stay out of their way.
The return trip was uneventful. It was downwind and I made great time. I always start out heading up wind so that the return will be downwind. Sailing downwind is easier and faster though it feels slower (the wind isn't on your face and the boat doesn't heel over on one side). Unfortunately, the winds were almost dead inside Alamitos Bay and since I was in a hurry to get home I finally bummed a tow through the deadest part from a kind passing motorist. Still it was the most satisfying adventure I've had in the boat so far.
Which brings me to my dilemma. My father in law is always upset at me for taking the boat out single handed. It is designed to be sailed by two people though it is fairly easy to handle by myself. But more importantly, I'm several miles off shore by myself. I don't worry too much about drowning as I always wear a life jacket and Long Beach water while not warm is not too cold. If the boat capsized and I stayed with it I could stay out of the water and get help fairly soon (or probably right it and be on my way). But what if I was hit by the boom and knocked out temporarily. I would float all right, but I'd be hard to see. Or what if I fell overboard and the sails were cleated so that the boat kept sailing. He really is right, I should have someone else with me.
On the other hand I love the adventure and the solitude and it is very difficult to find people who want to go sailing with me. OK, it's not hard to find people who want to go, but when it's Friday morning and it looks like the winds will be good in the afternoon it is hard to find someone ready and willing to go right then. To make matters worse, I like to go places. I would love some time in June (long days and good winds) to head up and make it to somewhere on the Palos Verde penninsula at least to Cabrillo Bay. (Truth be told, I'd like to sail it to Catalina, but even I'm not that dumb. Well, I am but I would want an escort boat. Hey people swim it with an escort boat.)That's a significant time commitmant and it is work sailing upwind that far in a small boat. Most of the people who want to sail with me think in terms of a couple of hours of sailing, but this could easily be 3 out and 2 back, not to mention rigging and derigging. Where would I find someone who wanted to drop everything Friday afternoon and spend 6 hours sailing off the coast of Southern California?
So the real question is how do I pursue the sport I love, as I love it, while maintaining some reasonable safety standards. (And on the other hand is my risk really that much more than commuting by motorcycle in LA traffic? Or by barely freeway legal moped as I used to do?)
Sailing / Sailing Races
I had been bugging him about when we were going to take it out and finally on Martin Luther King Day he said let's go. I was a bit disappointed with the date as it meant missing out on the family's first trip to the Aquarium, but I've been making a goal of improving on my male friendships (an area of my social life that has been week for decades) and I had been wanting to try his boat out for a while.
The boat needs a lot of work, but seemed to be sea worthy enough. It was fun to ride and both faster and smoother than my boat. Don't get me wrong, I love my boat and am more than willing to take it on adventurous trips, but this was a nice change of pace.
One thing that I thought was really exciting was that we saw a lot of sail boat racing. It did make sailing a bit more difficult as we had to stay out of the way of the racers.
As we headed back in the racers were also heading in. Between talking with them and looking things up on the web I discovered that we had seen the tail end of the 2009 US SAILING ISAF YOUTH WORLD QUALIFIER and U.S. YOUTH MULTIHULL CHAMPIONSHIP REGATTA. The were sailing single person dinghies (laser radials for both boys and girls), two person dinghies (420's with a slightly different version for the boys than for the girls), and open (both boys and girls competing with and against each other) multi-hulls (Hobie 16's). They were all fast agile little boats that were a lot of fun to watch. I never got very much into racing but it sure looked fun.
(Incidentally, my boat is two person dinghy rigged very much like the 420's. My boat is not nearly as high of performance boat.)
So the day was a double treat. Not only did I get to go sailing but I got to see some world class racing too.

Dueling Doctrine
What is the substantive difference between the Catholic Doctrine of the Infalability of the Pope and the Mormon Doctrine that The Prophet will never lead us astray?
We often poke fun at the Catholic Doctrine because so many popes through history were clearly corrupt, but a close reading of the catholic doctrine will point out that it does not refer to his personal character or dealings in secular matter only that when speaking on matters of doctrine he is "preserved from error".
Mormons likewise believe that the prophets are humans and suffer from all the frailties of humans, but the phrase "The Prophet will never lead us astray" is uttered regularly as if it were doctrine and that seems to be the same essential sentiment.
I'm also unclear on the scriptural basis for the assertion. I can trace it to a talk given by then Elder Ezra Taft Benson who cites Wilford Woodruf's talk defending the first official declaration. There is also an unsourced quote wandering around, but one never knows if unsourced quotes were every really said at all.
I'm personally bothered because I thought that personal revelation was the hallmark of our religion, not obeysence to any scripture living or ancient. It is by personal revelation that we know the Bible, the Book of Mormon, and all the other scriptures to be true. It is by personal revelation that we know that the prophets are in fact prophets of God.
Why then are we discouraged from seeking personal revelation on matters once the prophet has spoken on them? I know some will say that we are encouraged to get personal confirmation, but really it's only confirmation we are encouraged to seek. We are told to pray to know that it is true, not to pray to know if it is true.
I'll stop there for now. So tell me, what am I missing?

Pay $5 for gas
But that of course is something that either the market or the government will have to do. But is there something each of us could do? What if we each committed to paying $5/gal for gas. No I'm not saying find the most expensive gas in town, or just burn an extra $20 each time you fill up. But what if each time we bought gas we figured out what it would cost at $5/gal and squirrled the money away somewhere. Put it in your savings acount and save towards a vacation, or save it for when fuel costs really do soar. Or use it to add solar panels or donate it to energy research. Shoot invest it in energy research and get some profit back. Or save it to buy an electric car.
The point is two-fold. First we prepare ourselves for the inevitable return of high prices. If we are already paying $5 then the price shooting up to $3.50 is no big change on our balance sheet. Second, it encourages us to plan in terms of the higher price. How would assuming a price of $5 affect our choice of cars or our driving habits. It would be a shame if the lessons we learned during this summer's run up in prices were forgotten now that gas is again under $2.
I realize, that those who would participate in this are already environmentally conscientious, and no I'm not certain I have the discipline to do it myself, but it is an idea that I think could make a difference for individuals, and maybe, just maybe, for society.

The Old Ditch on Atherton
Here's what it used to look like. (Sorry I didn't figure out how to download just the picture.)
Old View
Then for several months the street was half blocked off so they could come in with the giant earth movers and pipes 3 feet in diameter to place the drainage safely underground. I wish I had a picture of that, but I never bothered.
Once the large work was done I expected them to quickly put up a drab barrier and be done with it. Instead the work dragged on and some stonework seemed to go in slowly. Then today they transformed it to a beautiful display of what look to be native (or at least climate appropriate) plants. I think it is beautiful and I am thoroughly impressed.
Good work Long Beach on a job well done.

On the Nature of Punishment
Now at this point the rule seems iron clad, perhaps just because I generally believe in following rules at least unless some compelling higher obligation prevents it.
What struck me as odd was when I learned what the penalty was. USC (the visiting team) would lose a time out. Some how I found this hillariously funny. Delineating a punishment seemed to lessen the impact and meaning of the rule. If the punishment were forfeiture of the game, then there is no way that USC would have even considered it. As long as the punishment was unstated it could be that severe, but once the punishment was stated the rule became almost pointless. This is especially true given that UCLA purposefully blew a timeout because they were in on the decision.
I guess somehow delineating the results always changes something from an iron clad rule to a choice where you weigh the advantages and disadvantages of a decision. As Garrison Keeler once said, there is no rule that you can't fight in hockey. There is just a rule that if you do you have to sit in a box for a little while.

The Curious Case of Benjamin Button
The movie is very long but never really drags. Excellent acting from an impressive cast Cate Blanchett and Brad Pitt center the cast, but the supporting cast is equally important and impressive. It is very emotional and generally poignant. So yes it is likely to win some oscars and I would recommend it.
