Andromeda

As I said in my last post, that night backpacking was a break through. Despite the confusion over Hercules I felt like I had finally connected things. However, it wasn't until today I finally solved the full Hercules riddle.

For our anniversary Carolina, my wife, bought me a small telescope. This encouraged me to spend more time looking at the stars. I learned more about the stars and where they were. I tried to figure out Hercules a couple of times and thought I had to some degree. I still had a lot of trouble finding less visible objects, but I was learning.

A few weeks ago Google add Google Sky to their Google Earth. It's pretty neat and gives a lot of info and ways to view the sky. It has helped me find stuff. I went out to see the lunar eclipse last week and Google Sky helped me find stars at the same time. I learned about the winter triangle and hexagon (yes, it's summer, but the eclipse was in the early morning so Orion and the winter stars were in the eastern sky). This was exciting because I tied even more of the sky together.

Last night I went out to find the Andromeda galaxy using my binoculars. I was in my backyard (not ideal, but at least it was clear, we are at 2400ft and there's not too much city light). I had tried a little before, maybe seeing it once, but not really sure. I was struggling, even looking at the wrong corner of Pegasus. Finally I found it! I started at Alpha Andromedae (Alperaz), which is also one corner of Pegasus. Then I found Delta and Epsilon And. (with much help from Google Sky) and onto Mirach (Beta And.). There it is a right turn to Mu then Nu And. and the galaxy is next to Nu And. Here is a chart (although Nu is missing in this chart).



I was able to repeat several times and this morning I repeated with Andromea in the West. This was very exciting for me because I have not found something like this before. I know it's not much, but it doesn't always take much to get me excited.

While I was out last night I looked for Hercules again. I found it -- also exciting. From my searching I noticed the Google Hercules lines were different than the Sky and Telescope chart I had been using. That's what finally helped me figure my Hercules confusion that I describe in my previous blog.

As a bonus, this morning I also found the Great Orion Nebula through binoculars. The fun never stops!

Hercules.

I've liked astronomy for a long time. Most of my life I've been able to identify the Big Dipper and the north star. A friend in college who was very into astronomy and had an 8in and later a 12in mirror telescope taught me a lot. I even took a class while at UCLA. Still, I never knew where most of the stuff was.

I eventually learned about Orion and then Sirius. And Cassiopeia. I studied star charts and went on a backpack where we saw satellites and an Iridium flare. A few years ago I had Pegasus pointed out to me. I learned about the summer triangle and Cygnus. I still couldn't really tie things together.

In June I went backpacking again and we spent a couple of hours looking at stars. This was a break through for me. I studied charts again. We identified Bootes, Corona Borealis and Virgo. I learned a little more of the sky, but I also saw for the first time how they tied to the Big Dipper. Suddenly I felt like I was starting to put together the pieces. I was very happy.

That night we also spent a lot of time looking at Hercules. We were very confused. Hercules is huge and the stars are dim. The star chart I had was confusing. Finally Hannah noticed that we were looking at it upside down. It was still confusing, but we could at least see it.

It turns out there are two ways of looking at Hercules. The traditional way was how our star chart was laid out. It is the "upside down" way. Alpha Hercules is above his head. His left arm points at Lyra, his back is toward Corona Borealis. The keystone trapezoid is his midsection. Here is the traditional charting:



Even the chart is upside down. Here is the picture right-side-up.




There is also a newer way to see Hercules. In this his back is toward Lyra and his head is the keystone trapezoid and leans forward toward Corona Borealis. His his left arm runs under Corona Borealis and points at Serpens. Here is the chart.



Part of the confusion is that Ophiuchus and Serpens are right below Hercules. Notices how this Serpens chart even connects Alpha Hercules to Ophiuchus.

Iraq

I like to think I'm analytical. I avoid politics but I've thought a bit about the war in Iraq.

• I didn't know if going there was right or not. I still don't.
• War is bad -- all sane people on both sides believe this. Not thinking this has got to border on insanity. Or at least terrorism.
  
• I'm glad Saddam is gone.
• I like the idea of showing that we won't tolerate human rights abuses nor terrorism.
• The Berlin Wall and the Iron Curtain imploded from outside pressure and internal dissatisfaction. Shouldn't we allow the Middle East to do the same?
• Just sitting back and letting terrorists get away with horrible crimes is wrong and scary.
  
• I've always felt the worse thing we could do is go then leave before finishing. We Americans can be such flakes and it makes us a laughing stock.
  

So, I've not been a great supporter of the war in Iraq but I don't like to just leave.

Last week I found out my daughter, Sarah, is slated for another tour of duty over there starting February 2008. I don't like it. I think it's bad for her and us. I find myself now completely against the war. I wish we were out now and I can't shake the feeling. No argument is good enough.

Today a friend at work sent me this video:


Wow! I find myself agreeing. How could we have been so stupid! It's from a political action group called MoveOn.org. I don't really want to jump on the bandwagon and support them. But I almost might.

I know there are other sides. I don't really want to listen to them right now.

Depressed.

Sunday I went to church feeling depressed. Why?

• I found out this week my daughter Sarah stands a good chance of being sent back to Iraq.
• Our church barely has enough money to get by. I'm the treasurer so I have to deal with it a lot. We don't have enough money because we are losing people.
• I'm reading a book by Donald Miller, "Blue Like Jazz." I really like the book. But I had just read parts that really convicted me. Made me feel like me and my church are failing God.
• Actually the last point isn't totally right. Part of my depression was that I read stuff that sounded like I should be convicted, but wasn't.
  
• If I ever wrote a book, I'd like to write one like "Blue Like Jazz." Now I know Donald Miller has beaten me to it and done a better job than I'd ever do.
  
• I did a search this week on my name, Eric Miller. There's lots of us. In fact, I found at least three doing things I've dreamed of doing. So if I ever got the gumption to pursue one of my dreams (fantasies?) I'd be competing against myself and I've already done better than I ever could.
• I'm behind on lots of stuff.
• I don't communicate as well as I should with my wife, Carolina. Worse, I feel I've had lots of opportunities to do better and let them go, mostly because I was too scared to step out.
• I'm gaining weight. I've gained over twenty pounds since November 2005.
• I had a physical. It all came out good. However, my cholesterol and blood sugar are worse, even though they're still OK.
• I get hyper a lot (see previous post, and I still hadn't made the thyroid connection).
• I got more depressed in church. Ivan Orellana spoke. He's not a polished speaker, but God has been speaking to him and he reached a lot of people. It's cool that a young person who grew up in our church is listening to God. However, I didn't get much out of it. I felt cold and cynical. I've just been dealing with a Jehovah's Witness paper on how John 1:1 does not say Jesus is God. It is poorly written and shows really bad thinking and lack of knowledge about Greek and language. I like people to think straight and I felt like I was judging poor Ivan based on my frustration with the silly JW paper.
• I've had periods of feeling old and seeing my life slip away.
  

Now I'm depressed just from writing my list!

Before church service I talked to friends and it helped some. Rick Curtis -- my first successful Greek student who is now DOM of our area (Director of Missions, which is Southern Baptist for Bishop) -- was visiting. After church service he saw me sitting by myself and talked and prayed with me. That helped a lot.

I really have a lot to be thankful for

• Carolina loves me and stays with me despite all my problems.
• My children are all doing well. They even talk to me and share their lives with me.
• Sarah is engaged.
• God loves me and has taken care of me for many years.
• Likewise our church. Even though we've been on a financial edge for almost a year, we've always managed to pay the bills. We've even raised a lot of money to fix our leaky roof.
• I've had a wonderful summer. I've never been so active. A 25th anniversary cruise with Carolina. Backpacking to beautiful Jennie Lake. A trip to Yosemite and Hike up Half Dome. Two trips to Arcata -- both relaxing and good chances to be with Carolina and visit Ruth.
• I've got to spend time with my son, Dan. Playing tennis, talking and during the Yosemite trip.
• Likewise I've had some good times with Sarah, including the backpack trip.
• I like all my children's significant others. More than like, they are all very wonderful people.
• I have a good job. It pays well. I get to sit in a cubicle and not be outside in the elements. I mostly get to do stuff I like. Right now the stress level isn't even too high.
• I've found very good friends at my church.
  
• Church has helped me a lot to be more honest and open to what the Bible and God really say.
• Despite having arthritis and hypothyroid, I feel really good and can be physically active. If I lived even 50 years earlier I'd probably be crippled from my arthritis. Praise God for modern medicine.
• Of the five of us who hiked up Half Dome, three of us made it. Dan and I were the only ones who were not really sore and suffering afterwards. I conquered my fears and did better than I possibly hoped.
• I feel much more confident around people than I ever have. This is huge for me, the boy who hid in his mom's skirts, the young teenager who didn't even talk to a girl until he was a sophomore in high school, who was scared to use the phone until well into adulthood.
• I have food, clothes and a nice house. I'm richer than most of the people in the world. I have time to enjoy life.

OK, that list helped. It's hard for me to see the positive. Thanks to all of you who God has used in my life.

Hyper

Many years ago I used to fall asleep in meetings and at church. I got bored easily and fought my lack of discipline to stay awake. Then I found out I have hypothyroidism -- my thyroid is low. I take thyroid replacement medicine. I get tested regularly to make sure it's OK and sometimes need to change dosage. Since then I've almost never dozed off when I shouldn't.

Recently (last six months to a year) I've found myself getting uptight and hyper very easily. It's not that I didn't before. It just seems to happen more now. And I don't sleep as easily. Am I just noticing more? Am I under more stress? Am I losing faith in God?

Several months ago my test showed my thyroid was slightly high. Last week had my annual physical and got tested again. My thyroid was a bit high again, so my doctor adjusted my dosage down.

Just yesterday I made the connection. Maybe I'm hyper because my thyroid is too high. Usually when it's adjusted it's because it's too low. I have never had it high for very long so I don't really know what it feels like. I guess I'll find out if thyroid is my problem in the next few weeks.

People want to be real, to feel their raw and actual emotions. How much of that is just chemical? How much of what we call moral or immoral is also just chemical? Is it time for Equilibrium?

Speeding Ticket

I got a speeding ticket a week ago Saturday. It was on our way to visit our daughter Ruth in Arcata, and happened in Mendicino County, between Willits and Eureka. It's a beautiful section of the 101, redwoods all over. I've been warned they're pretty tough on speeders. And I usually just enjoy the drive. But I was into going fast and had two other cars with me (safety in numbers). It even occurred to me how stupid I was being, but I paid no attention. I came over a hill and around a bend and a police officer was parked behind a sign. I actually was alert enough to see him and slow down, but too late. He got me (and let the two behind me go, so much for the safety thing) on his radar doing 83 in a 65 zone. He turned out to be very nice. Smiled. Told me that he'd reduce my speed since I just came over a hill and wasn't doing anything else that was dangerous. He explained that by reducing my speed below 80 I'd avoid the automatic doubling of the fine in Mendicino county and be eligible for traffic school. Very nice, but also a not-to-subtle warning not to do it again! I signed my 75 mph ticket and we were on our way. We drove the speed limit the rest of the way up and all the way home (which added at least an hour to our drive home). I've been thinking about changing how I drive and learning to relax and not hurry so much.

How much of my morality is governed by not wanting to get caught?

Good in people

There's a lot of evil in the world. Most of it is due to people. To us. Large cities have a lot of evil because they have a lot of people. However, there is also good in people. The hike up Half Dome brought that out. For me it was one of the most enjoyable parts of the hike.

It's not that everyone was all wonderful. There were a lot of people on the hike. Some seemed rude or arrogant or just in a hurry. The reactions of the animals to us showed that many ignored the admonitions to not feed the animals. At times bathroom conditions and trail trash showed a lack of respect for the park.

Difficulty and danger put us on our best behavior.

On the hike, though, it was mostly good. People were polite and usually greeted us on the trail. People went out of their way to be encouraging and helpful. Most of us were thrilled to be in such an awesome place and just wanted to share with those around us. The difficulty of the hike also tended to filter out people who weren't pretty committed to being there.

People were especially polite on the cables.

The switchbacks and even more the cables really showed people at their best. On both people always let others pass by when needed. There isn't a lot of room on the switchbacks so we were always looking to see if someone was coming the other way and when we could stop or when we could pass. The cables have even less room and stopping at the safety of the poles was important. We always offered to let the other person go and politely negotiated our passing around them.

People coming down were always encouraging us who were going up. We returned the favor on the way down. I remember one man coming down as I was climbing the cables. He told me that the cables leveled out just above him. That was very encouraging -- knowing what lay ahead was important. On my way down I met an older man who was very tired at about the same spot. I was able to pass on the same favor.

We often shared our fears. In earlier posts I've mentioned the man who was scared of heights and the woman that wanted to climb the cables with us. I was involved in many exchanges on the cables of this nature. Again those coming down often provide moral support to those going up.

There was a friendly club atmosphere on Half Dome's summit.

At the summit people were also very friendly. There was no longer the exaggerated need for politeness we felt on the switchbacks and cables. But we were all very happy to be there and to share with whomever was around. It was kind of like we were all now part of a special club. Some of our normal barriers were dropped and we could be very open and friendly.

How nice avoid the evil of the world and to catch a glimpse of how good people can be, even if only for one day.

Go For It

Falling off the cables is a bad idea.

My last post was about limits. I had a very personal reason for thinking about limits on our Half Dome hike. I came close to swimming beyond my limit on our backpack to Jennie Lake a month before the Yosemite trip. I was afraid I might make the same mistake with the cables at Half Dome. I wanted to go for it, but was afraid I might under-estimate how tired I was and slide off the mountain because of exhaustion.

Waiting for the cables.

We waited about twenty minutes for the cables to clear. During this time I was fairly nervous. I still thought about being exhausted even though I felt very strong. The hike up the switchbacks was tough, but I was fine. I keep feeling like I wanted to turn back. However, I also knew that if I turned back I would always regret it. I decided to leave my knapsack. That made hanging on the cables seem more manageable. As soon as the cables cleared I wanted to go. I felt if I waited any longer I would chicken out.

On the cables, finally.

I went for it. Dan and I walked to the cables. I asked Dan to stay with me -- I would feel better. We walked by a woman who said she was scared and could she climb between us. I said I was scared too, sure. I was focused on going up and just kept walking. Rex said he wanted to go behind me since I knew more about the route. OK, whatever. That made it me, Rex, the woman and Dan. I just focused on the cables and the rock at my feet and started climbing. Once I was on the cables I was fine. I even looked around once or twice halfway up.

I was still in a nervous state though. About 2/3 of the way up a woman coming down asked if I had seen her friend. I said no. It wasn't until the next morning I realized she was asking about the woman who asked to climb between Dan and I! In fact they were both part of a group of woman who were on top. The group included the 8 year old girl I mentioned in my last post. I also talked with on of their companions for several minutes on the summit. I am a spacey person, but it also shows how hyped-up I was.

I had no problem. It did require some pulling on the cables, but even my arthritic hands could do it. It is by no means a straight pull uphill. Mostly the cables are used to keep from sliding back while climbing with your feet and legs. Plus you can rest every 6 feet or so on the 2x4 across the cable poles.

I saw this badger at the top of the cables on the way up and down.

I got to the top, met some people, looked around some and then realized Rex wasn't there yet! Yes, I was spacey! I went back to the cable top. Somebody I didn't know came up. Where were Rex and the woman and Dan? Rex showed up after a while -- the man I saw had passed everyone! Dan came a bit later and he said the woman was coming up behind him. I had just gone, focused on what I was doing, with no thought for anyone else.

I regretted that I left my knapsack below. Taking it would have been no problem, although not having it made passing the people coming down a little easier. I wanted some water and I wanted to have my camera. I'll bring it next time!

Coming down the cables.

Coming down the cables was scarier than going up. It wasn't too bad though. Most people go down facing down. I started that way too but started sliding a little which made me nervous. I turned around and descended backwards most of the way. A little slower but I felt more in control. I again was able to look at the view a bit. Looking too long seemed like a bad idea -- everything is down and it is easy to get dizzy. I even did OK when we had to wait for the boy to be helped down.

I'm so glad I went for it. I regret leaving my knapsack on the shoulder I regret being a space cadet and not being more help to the woman climbing with us or to her friend. It was necessary for me to be focused and get over my fear. That I don't regret. I am a fearful person who overcame a major fear. I also proved to myself that I was physically up to the challenge. Thanks to God for getting me through!

Know Your Limits

It's good to know your limits. I learned a lot about limits on our hike.

Don at his limit.

I mentioned in my "Stay with your friends" post that one of our group was in real pain. Don pushed far beyond what I think most people would. He also had the grace to know that he needed to stop and that he was slowing us down. He knew his limits. After he had rested a couple of hours he felt like pushing on to the summit. But he again realized that would hurt the group and gave up on it.

Climbing the switchbacks.

On the way up the switchbacks I passed a couple coming down. The man told me he had made it up the switchbacks. He talked about the rock scramble at the top and said it looked pretty scary. However, he had made even though he was afraid of heights. I'm not sure why he shared with me -- was he telling everyone? He seemed very happy to have accomplished this. His last comment was that he turned back at the cables. He knew his limits and had a very happy hike despite not making the summit.

The shoulder of Half Dome at the top of the switchbacks. Robin reached his limit here.

Robin was the last of our group up the switchbacks. Dan, Rex and I were waiting for the cables. (A man was coming down awkwardly with a group behind and it seemed good to let them get off first.) Robin collapsed on the ground and asked for water. I gave him some. Dan asked if he was ready to climb the cables. He said no. He had reached his limit and had the wisdom to not push too far.

Going down the cables after a boy was helped off them.

A little after we started down the cables we got stuck for 10 minutes or so. A small boy (we heard 5 years old) got scared and was helped down by the search and rescue team (I saw them at the summit -- they had just climbed the face. Are they always there? Was it just good fortune?). The boy, or perhaps his father, exceeded his limits. It was all OK, but he probably would have been happier if he had stayed on the shoulder, still an impressive achievement of such a small one. While on the summit we saw a girl not much older -- she was about 8. Limits are very individual. It's probably a good idea if we parents know and respect our children's limits.

My last story was kind of a downer. I don't mean to rip on the boy or his father -- it's very hard to know when you will get scared and when you will be exhausted. My main point is to celebrate people who know their limits and respect them, who do not go beyond just because of ego or peer pressure. The long, hard and scary Half Dome hike helped me see that more clearly.

First Aid.

As we left Taft Point a couple was just arriving. The man passed by. The woman came down a bit later. She had fallen on a rock and scraped her hands. Some skin had peeled away -- painful but not very serious. She was asking (him, us?) for a bandage. Rex had a disinfectant wipe. I had some antiseptic cream. The man had bandages. He kind of criticized his mate for falling "You need to be careful on the rocks." It seemed to me that he was embarrassed that she fell and was asking for help.

Hiking away from Taft Point.

A couple of observations.

I felt good about being prepared and being able to help. It was an accident though. I brought the first aid stuff and everything else in my knapsack because I wanted to get used to it before the big Half Dome hike the next day. I didn't really think I'd need it on the easy Taft Point hike. Never know when opportunity will arise.

Even though I'm quick to judge (for example), I would have never thought to judge the woman for falling or the man for being with a woman who would fall and ask for help. Yet this seems to be what the man was worried about. I did judge him for his bad attitude and lack of compassion. Hmmm...

However, before I could walk away totally righteous, I remembered how on a number of occasions I've acted the same way to those I love. How odd that we do this, especially since love and compassion are so beautiful.

Wow!

Looking at Half Dome from the top of Sentinel Dome.

As we hiked around various places in Yosemite, we were often overwhelmed by the beauty. It was awe-inspiring. We see a view, exclaim, stop and take pictures. Soon after continuing we'd see an equally amazing or even better view.

Looking at Yosemite Valley from the top of Half Dome.

This just went on and on. We would run out of words and just say wow. Or be silent. At times we actually got tired of yet another incredible sight. It became too much.

Looking down (4800 feet!) over the face of Half Dome.

Is that what God is like?

A Yosemite secret.

I'm going to let you in on a secret about Yosemite. There aren't too many -- Yosemite is a pretty popular place. And I probably shouldn't do it -- no need for more people. But you're my friends. This is for you.

The big secret? Get out of the valley. Yes, Yosemite Valley is awesome. But it is also very commercial and crowded. There is a lot more to be seen.

I suppose it's not that big of secret. After all, the trail to Half Dome is almost always full of people. However, hiking to Half Dome either involves backpacking or a 14 or more mile hike in one day, some of it on very steep trails. By all means if you can make the hike you should. It's worth every sore muscle and blister.

What's not so well known is the many other trails. I haven't been on most of them. Many of them can be long hikes or backpacks. Here are some we hiked and really enjoyed.

Mt. Broderick, Liberty Cap and Nevada Fall viewed from the Panorama Trail at dawn.

Panorama Trail. Take the tour bus to Glacier Point. Hike down the Panorama Trail to Yosemite Valley. This is a 8 mile hike, so it still involves a fair amount of hiking. But most of it is downhill. And the views are awesome. We started in the early morning which you can't do with the tour bus. We heard Nevada Fall, saw deer and other animals and watched the sun rise on Yosemite. Unforgettable. We also got to see the sun set on the lower part of the trail -- the John Muir Trail -- since we detoured to climb Half Dome during most of the day.

Cathedral Rocks and El Capitan at the entrance of Yosemite Valley viewed from Sentinel Dome.

Sentinel Dome. This is a short 1.1 mile hike. It starts from a trail head on the Glacier Point road about 2/3 of the way to Glacier Point. The hike climbs about 400ft. You arrive at Sentinel Dome which is 8100ft high (just below Half Dome's 8800ft) and towers 4100ft above the Yosemite Valley floor. 80% of the thrill of Half Dome with 1% of the effort.

Taft Point overlooking Yosemite Valley.

Taft Point and The Fissures. This also is a 1.1 mile hike. It starts at the same trail head as the Sentinel Dome hike. The elevation change is about 300ft but it is mostly down to the point and then up on the way back. The hike itself is much prettier than the Sentinel Dome hike with a lot of trees, foliage and even animals along most of the route. The Taft Point outcropping has many cuts on its side which are known as the fissures. Again the views are spectacular.

Half Dome at dusk viewed from Glacier Point.

Glacier Point. Can't hike at all? Go to Glacier Point. It is a 45 minute drive from Yosemite Village. It's not so secret -- you will run into crowds during the day. Want a real thrill -- get there for sunrise or sunset. We were there in the first light of dawn for our Half Dome hike and saw sunrise, as I mentioned above, on the Panorama Trail. Earlier we went to see stars at night and arrived just after sunset. The lighting and views we saw caused to just sit and stare until the light faded. The star viewing was spectacular too.

My blog, stupid Myspace, personal stuff, quantum apology

I haven't posted much. I like posting personal stuff on Myspace because my fans are there and they read it. Thanks to both of you. Not that I post huge amounts most of the time anyway.

However, I just discovered yet another deficiency of Myspace. Myspace removes the number sign (#) from a post. This means that photo links to Picasa don't work. Myspace is just too damn smart for its own good. Blogger is much more straight forward and capable. I may be posting a lot more here.

Lastly, my only real blog here -- the one about Quantum gravity -- has gotten a lot of comments in real life. Almost all were that people didn't understand. Yes, it's a very confusing blog. I apologize. I just tried to get my thoughts down and hoped I could expand later. Later never came. I'm still thinking about it. Kudos to Thomas for not only understanding, but taking up the gauntlet and reading the book himself. Physics is not for everyone, but it is fascinating to those of us who have the inclination for it.

Stay with your friends.

I put this blog on Myspace. Myspace was unable to correctly handle the picture links so I'm reposting here with pictures.

Yosemite again. The big hike up Half Dome. The five of us have now hiked over 6.5 miles of the 10 miles to the top. There will be an 8 mile hike down from the top. We are leaving Little Yosemite Valley and starting the real climb part: 2800ft up in 3.5 miles. I've been studying the hike forever and I have a schedule in my head. We're behind schedule. I'm also nervous about my ability to make it. I'm scared of the steep switchbacks at the top and most of all the cables up the very steep rock at the end.

We have taken another rest stop and I'm frustrated. One of our party is a bit slower and needs more rest. The start of the climb is really hurting him. I'm ahead, trying to push the pace a bit. Lots of people are passing us. After a short rest, I just start hiking.

Looking down at the climb out of Little Yosemite.

In some ways this was not so bad. We didn't hike completely together -- we would spread out a bit then stop and re-group. I was frustrated and hyper and when I'm like that standing around is not good. Doing something helps. If I stayed I probably would have said something mean or at least conveyed a very bad attitude.

However, I didn't just walk. I kept going and going. Even when Dan (my cross country running son who could have easily outstripped all of us on the hike) finally caught up with me, I kept going for a while. I wanted to reach a trail junction. To have some sign of progress. I wanted to go faster. To not be embarrassed at being slow. To have some confidence that we (or at least I) would make the top.

More of the climb out of Little Yosemite.

Finally we stopped. I realized the junction was farther than I thought and I knew I couldn't just keep going alone. We waited a long time. Everyone caught up and after resting we pressed on.

The first long rest stop with a view of Half Dome.

A while later we reached the junction and again waited and rested for a pretty long time. We watched many more people pass us.

Resting at the junction.

Somehow in all of this God was getting through to me despite my arrogance and lack of faith. Yes, arrogance. I didn't want to be seen as slow by all those around us. Yes, lack of faith. Lack of faith in my friends and lack of faith that God would take care of us no matter what. I finally accepted and even embraced that we needed to stay together. If we all failed together that was better than just going off on our own. If we made the top, it was best if we all made it, even if we got back at midnight (we did bring flashlights and the trail is pretty obvious even in the dark). The best way to ensure all made it was to stay together.

Of the five of us, Dan went ahead a little, but never left. The other two fell in behind our slower friend. I was helped by their example and did the same, bringing up the rear. I took time for pictures and enjoyed the scenery and was content to let what happened happen.

Trudging up the hill together.

Finally about a mile from the top our slower friend stopped and said he couldn't go up any further. He watched our stuff and sent us on, not wanting us to lose the summit on his account. We went on our way. Three of us made the top, the fourth reached the cables before giving out.

One of us came down a bit early from the top. He hurried to our friend and allowed him to start down early. We made it back down to Little Yosemite Valley fairly quickly.

From there though, our friend was again hurting a lot. We took a couple of good rest stops. We hiked slowly down the last several miles as the sun set. We didn't get back to our car until about 9:40pm.

Hiking down to Yosemite Valley as the sun set.

As we descended into Yosemite Valley I took it upon myself to stay behind our friend and hike at his pace. Penance for my earlier attitude? Perhaps. But more than that it just seemed like where I needed to be. To as much as possible share my friend's pain. That last sentence makes me sound kind of saintly, but I'm not. I just felt good about where I was. About the hike and getting to the top. But also about being with friends and doing something together. And glad that God could change my foolish attitudes.

Quantum Gravity

I just read Three Roads to Quantum Gravity by Lee Smolin. I was surprised at what he had to say. He made several points that gave me much food for thought:

1. General relativity implies there is no such thing as space and time without objects. Space and time are not independent entities. I knew space were not absolute, but had never thought of this extreme position before. Related to this there are no objects, only processes.
   
2. Quantum theory disagrees with relativity on precisely this point. Quantum theory assumes a static space-time background and so directly disagrees with relativity. This is why the two theories cannot be merged.
3. String theory is also based on a static background. According to Smolin this means it cannot be the correct theory. However, it may be a useful tool just as Newton's mechanics are very useful even though they are wrong when relativistic speeds and gravity are involved. String theory methods have produced a lot of interesting results.
   
4. Smolin and loop quantum gravity theorists propose that space and time are not continuous but discrete. In the 19th century materials were thought to be continuous. We now know they are discrete -- they have molecules and atoms. Smolin compares this situation to space. His main line of argument is that black holes appear to have a finite amount of information (proportional to the area!). If space were continuous black holes should be able to contain an infinite amount of information. This is mostly theoretical but it is testable.
   

My thoughts:

1. Despite these ideas being new to me, they seem to make a lot of sense. My feeling is that they are good. They do require a lot of re-thinking.
   
2. Does #4 mean real numbers and real analysis do not really apply to our universe? Do we only need integers and number theory?
3. Likewise do #1 and #4 mean that the universe is finite? Or at least that we cannot ever know if it is infinite? Smolin presented an idea I have heard before about how we can only know so much of our universe because of the speed-of-light limit. Basically we cannot know anything that happened too far away and too recently for light to have reached us. For example, we cannot know what happened yesterday on a star 100 light years away from us until 100 light-years from now. Since the universe is less than 14 billion years old, we cannot know about anything over 14 billion light-years away.
4. If the universe is finite must there be a first cause? Here I move away from science into philosophy. I've always liked Aristotle's first-cause argument. If the universe has infinities it is not clear his argument works. Without infinities it seems like his argument is more valid. Quantum physics also argues against strict cause and effect and there are probably physicists (including Smolin) who could explain why this is still a weak argument.

Needless to say, I really liked his book and am tempted to read it again. It's been a long time since I've run into so many good new ideas. I was also impressed by how well he explained many physics topics that have until now been rather hazy to me.

My new blog.

I have a blog on myspace but it is more of a personal interaction. Here I hope to write a little more thoughtfully. We'll see what happens.
