One of the reasons I got interested in physics was because I have always been interested in the “question of free will.” Physicists don’t like to talk about free will much, especially since learning what quantum theory has to say about free will seems to put you smack dab in the middle of the measurement problem in quantum theory. In many ways, what I’m most interested in is not the question of free will, which I find too often to be an overly anthropocentric enterprise, but more the question of the determinism / indeterminism of physics. But the “free will question” has played a major role in shaping why I choose to do physics.
As so the question becomes: why was I interested in free will? Most of it is surely due to my older sister Cathy. You see Cathy is a little person. No one knows exactly what syndrome she has, but it causes her to be lopsided (one arm and leg shorter than the other), she has very poor vision and hearing, and has some mental difficulties. This makes it all sound really bad: which it is definitely not because Cathy is an amazing light in our family. She works at the local library in Yreka, loves to listen to her John Denver tapes, she loves to watch Jeopardy, and is, in general, a very happy person who brightens the lives of her many many friends.
But if you grow up with a sister like Cathy you can not avoid thinking about why you ended up the way you are and why she ended up the way she is? Was it fate and totally out of the hands of human choice? Science, and physics in particular, is the path one is reduced to in order to possibly find any answer to such a question. While we can argue forever whether reductionism to fundamental physics is central to answering this question, there can be no doubt that understanding the role of determinism and indeterminism in physics will have a profound impact on our view of this question.
On the other hand, Richard Feynman said: “Do not ask yourself… ‘how can it be like that?’ because you will lead yourself down a blind alley in which no one has ever escaped.” I don’t think Feynman was talking about science here: scientists spend much of their time answering how it can be like that. I think Feynman was talking about asking for reasons which somehow satisfy us as humans: answers that will give us short sentences explaining why. There are simple important questions which might have simple concise explanations, but finding these explanations seems impossibly difficult. And this is how I find myself coming full circle. Because this point of view, that there are simple questions for which there aren’t answers which can be found in a short time (and once we find them, we’ll know we’ve answered the question) is basically the complexity class NP. Which is computer science. The field, besides physics, which I most deeply admire.
So fate not only made me a physicist, but it also made me a computer scientist.
And the only question left remaining is whether or not it was destiny that I was born at a time when I could participate in the unfolding of the field of quantum computing, which merges physics and computer science like never before?

I have a month off and these all go in two special boxes and will travel with me on my trip around the west. How many will I get through before I start at SFI? Let the betting begin at zero.

Yahoo headline:
FBI Issues Terror Warning for Calif., N.M.
Which either means (1) the terrorists are following me on my trip to find housing or (2) I am subject of the terror warning. Well (2) is obviously not true, but I suspect I will be getting some unlisted IP address hits to this web page soon. And (1) is certainly strange, as I am but a bit player in this grand old world. On the other hand, I did see “Fahrenheit 9/11” in Toronto just in case the U.S. version was censored. Quoteth Nirvana: “Just cus you’re not paranoid, don’t mean they’re not after you.” Every day, the world more philipdickian.
Wednesday and Friday
To the city different I go to find me some housing (842 miles!)
Blessed be books on tape. Or perhaps I will work on memorizing some stories again. At one point I entertained memorizing a Shakespearing play. I think I will work on another Borges story. Perhaps the short “Borges and I” or as a long term project “The Circular Ruins.”
The Guitar of Time Travel
Inside of physicist Dave, behind skiing Dave, squished under happy Dave, there lies just a tiny bit of music Dave. Today I did something I haven’t done in too long a time—I picked up my guitar and played a few songs. OK, I have no talent! I’m blonde: whateeever!
Strumming my guitar on a warm Southern California evening put me in mood nostalgic for similar days spent in the summer of 96 sitting in front of the house at 270 Holliston. Which in turn reminded me of the man who sold the world.
We passed upon the stair
we spoke of was and when
Although I wasn’t there
he said I was his friend
Which came as some surprise
I spoke into his eyes
I thought you died alone
a long long time ago
Oh no, not me
I never lost control
You’re face to face
With The Man Who Sold The World
I laughed and shook his hand
and made my way back home
I searched for form and land
for years and years I roamed
I gazed a gazely stare
at all the millions here
We must have died along
a long long time ago
Who knows? not me
We never lost control
You’re face to face
With the Man who Sold the World
–David Bowie
One Large Sundial
On my way home from Yreka for my sister’s birthday, I stopped by the Sundial Bridge in Redding, CA. It is a very strange feeling seeing this gigantic foot bridge over the Sacramento river in the middle of little old Redding. Here are a few pictures:
The bridge was designed by Santiago Calatrava, who also designed the olympic stadium for the upcoming olympics in Rome. On the summer solstice, the bridge acts as a large sundial. I wonder if anthropologists 4000 years from now will wonder what we used this gigantic sundial for?
RuhRoh Update: Panos points out that the olympics are in Athens not Rome. God am I an idiot these days: what was I thinking? Also it is the roof of the stadium which is being designed by Calatrava, not the whole stadium. See the comment section for some pictures of the stadium.
On Top of Mt. Shasta
When I first caught sight of it (Mount Shasta) over the braided folds of the Sacramento Valley, I was fifty miles away and afoot, alone and weary. Yet all my blood turned to wine, and I have not been weary since. – John Muir, 1874
Unlike John Muir, I don’t recall the first time I saw Mt. Shasta. Having been born and raised in the nearby town of Yreka, the 14162 foot tall Cascade volcano has always been a part of my life. It was only after I left Yreka to attend college that I could return to Yreka and begin to appreciate the wine that flowed in Muir’s blood. It is hard to describe the majesty of Shasta: the way the volcano dominates the sky, the very different mountain presented to viewers from different perspectives, the white wonderland after a winter snow. Like most people spoiled with such beauty, it is easy to grow accustomed to the mountain. Easy to grow used to a unique gem.
My dad, Larry Bacon, climbed Shasta somewhere around ten times. Almost all of these climbs where before I was old enough to accompany him. I retain vague images of his climbs, shown to me on old slide-shows and told to me in humorous stories, but we never climbed the mountain together. A bad back, age, and time conspired, but this father’s day weekend, my dad and I finally made our joint ascent on the majestic Mt. Shasta.
My dad was full of strange little songs, whose origin, content, and tone were always of a quite questionable nature. The strange songs he would sing during his morning shower were a constant source of bemusement to all who had the luxury of hearing his rhapsody. One of the songs he liked to sing was a version of “On Top of Old Smokey”:
On top of Mt. Shasta
all covered with snow
we lost our hike master
to the rock piles below.
All blood and guts
he lay there below
our poor hike master
had stubbed his toe.
It was with this song, then, in the back of my head, that I stood in the parking lot of the trail-head Bunny Flats on the morning of Friday June 18, 2004, staring up a the dominating southwest side of Mt. Shasta:
The forest in this picture is clearly obscuring “the rock piles below” where, I could easily imagine, legions of hike master’s bones lay in their final resting places. To crack this mountain would require an elite team of experienced climbers ready for the challenge of a two day ascent. Mistaking the word inexperienced for the word experienced, however, our climbing group consisted of three first time climbers, myself and my two friends Luis de la Fuente and Patrick Hayden and a geologist, Luis’ dad Juan, whose last climb of Mt. Shasta occurred before all three of us newbies were born. Fresh blood be damned, there is nothing like the arrogance you can feel in your hiking skills just before a big climb. Here I translate this arrogance into my best Babe Ruth intimidation:
So, at about 11 a.m., we left Bunny Flats, loaded with gear to our day’s destination, Lake Helen. Our first rest came at Horse Camp, where we filled up our water bottles with “the cleanest water in the world” from the spring beside the Sierra club cabin. Here Luis rests under the shade of the cabin:
Luis, unfortunately had a cold equating to a fraction of his normal lung capacity and was therefore in much pain throughout much of our trip. Here we find this pain written into the creases on Luis’ face:
In the above photo, Patrick is hidden behind his hat and Juan is hidden behind Patrick.
The hike to Helen was quite fun with big packs on and medium soft snow. Here two lone hikers ascend away from the main path to the campsites at 50/50 flats:
After some trudging up some 3500 feet, which looked something like this
we finally arrived at Lake Helen, elevation 10400 feet.
Here are our two tents at Helen:
There is nothing much nicer than the feeling you get after setting up your tents. This is clearly why three quarters of Patrick and I have such big grins on our faces
Arriving early to Helen gave us plenty of time to stare up at the Red Banks, and wonder, where the heck is the rest of the mountain?
To bed at 8 p.m. for an early start of 4 a.m. the next day. Sadly I did not know that the tent I shared with Patrick had a window and that indeed this window was open during the night. I snuck in 4 hours of good hard sleep and then a lot of freezing off of my toes to rise at 3:45 a.m. After a bagel and some frozen Gatorade, we left camp at 4:30 a.m. There were about 10 headlights already proceeding up the hill below the Heart on Shasta, and as we left and looked back we counted around 30 more following us up the hill! Truly an amazing site all of these lights climbing up the mountain in front of you. Indeed the site must have inspired the still sick Luis who summoned some sort of superpowers from his quarter lung and made a massive push up to the chimney of the Red Banks. In the morning sun, Shasta casts a shadow onto the surrounding territory below, and, as you can see in this picture, even onto the morning haze on the horizon:
Here’s the view we had looking up at the Heart (the bare area in the middle of the picture)
Amazingly, given the sick Luis, we trudged up this part of the mountain and passed all of the people you can see in the picture in front of us.
So, up through the Red Banks we climbed. Sadly, I don’t have photos of the chimney we climbed in the Red Banks. When we finally reached the top of the Red Banks, we encountered our first taste of the famous Mt. Shasta winds. Just below Misery Hill, we stopped to take off our crampons and were blasted by some nice cold hard winds.
We all sort of climbed up Misery Hill at our own pace. This was a part of the hike where I could just trudge along at a slow steady pace up the cold windy slope. I felt very alone and my thoughts drifted to thinking about my dad. How many times had he been up through this same misery? What was he thinking when he made this slow solitary climb to a reward, the peak, totally hidden from view? The reward was the climb, the beauty of everything around you, a small dot on a big hill. About half way up Misery Hill I found that if I climbed over to the right, off of the bare hill and onto the snow, the climbing was much easier and there was little to no wind. Always be on the lookout for ways to turn misery into a serene climb.
At the top of Misery Hill, we got our first good view of the true summit of Shasta, a spectacular looking final hill with a few little dots, hikers, dwarfed by the final summit
Hiho, Hi ho, it’s off to the summit we go:
Finally, the top! At 8:45 a.m. we reached the summit of Shasta. The weather was absolutely fantastic: very little wind and quite pleasantly warm. Amazing! The views, to say the least, were astounding. Here at 14162 feet, Luis signs the log book:
The final summit of Shasta has three high levels, the highest being on the south east of the summit. Yreka is to the north of Shasta and so we climbed over to the north west peak in order to spread my dad’s ashes.
So, there I found myself, standing on top of Mt. Shasta, looking north across the Shasta Valley to Yreka. We didn’t perform any ceremony, so to speak: pomp and circumstance were the last things my dad would give a hoot about. I had carried a portion of my dad’s ashes in a neon blue cylinder. Of course the damn thing was crazy hard to open, but I finally twisted the top off. The wind picked up a bit blowing to the south east. Thus I was able to throw my dad off the edge of Shasta, toward Yreka, such that he would splatter all over the rock’s facing Yreka. Of course this meant I got some of my dad blown in my face and stuck in my teeth. And here lies Larry Bacon (1940-2004):
As one might expect, many of the local Native Americans regard Mount Shasta as a sacred mountain. In fact, one of their legends is that the world was created from the summit of Shasta downward. Shasta was so special to these tribes that climbing above tree level was strictly prohibited. The only reason one could climb above tree level, according to this custom, was if you were called to the mountain to die. I like to think that the mountain called my father to die. It’s just that the mountain called him nearly forty years ago, when my dad visited Yreka looking for a job. Called to the mountain, he found his paradise: the beauty of Siskiyou county, the community of Yreka, his family, wine, dogs, gardening, cooking, history, the stars, and everywhere a sense of humor and amusement at the surrounding world. All of this, the mountain gave to my dad. And to the mountain, now, my dad has given a small part of himself. Indeed, if Shasta were to explode today, bits of my dad would fly out directly toward Yreka, where so much that he loved, lived and lives.
A quick photo with Patrick and Luis
and with Luis and Juan
and then on down the mountain we went. At this point the summit was getting to be more crowded and on the way down we were quite jubilant. Here Luis and Patrick mock the other climbers who were struggling to the top by pretending to be stuck in super strong Shasta winds:
Not too nice, fellas!
Here is Patrick contemplating the top of Whitney glacier
and a nice picture of Shasta’s smaller twin, Shastina
The best thing about coming down a mountain like Shasta is glissading. Here Luis demonstrates dubious form:
Patrick attempted to glissade through the chimney at the Red Banks. By attempted, I mean, he gain a ton of speed, attempted to dig his ice ax into the snow, lost his ax, went flying down the chute, before self-arresting on the side of the channel. Sadly I was too busy yelling at him to take pictures of this fantastic feat. But here is Patrick contemplating whether to attempt this foolish act or not:
Here my butt gets really really wet:
Well, that’s the story of how my dad went to the top of Mt. Shasta one last time. So if you’re ever driving on I-5 past Shasta, I hope you look up at the mountain and wave hi to my dad. He’ll be looking down at you, and laughing his ash off.
Shasta Bound
Patrick Hayden, Luis de la Fuente, and I are going to attempt to climb Mt. Shasta next week. Please do a weather dance in our honor next Friday and Saturday. Here is a picture of current conditions on Shasta courtesy of the fine ShastaCam
The route we will take to climb Shasta goes up Avalanche Gulch which is to the right of the ridge in the middle of the picture. The route goes to the left of Thumb Rock which is the silhouetted feature at the top on the right of the picture which, well, looks like a thumb. To the left of Thumb Rock is a big long line of rocks called the Red Banks (in summer they really show up as a stark red line.) Below the Red Banks is a big bare spot. This is The Heart and is remarkably free of snow year round. The route you take is to the right of The Heart and goes through the right side of the Red Banks and then up to the Summit. The plan is to climb from Bunny Flats to Lake Helen on Friday (6860 ft to 10440 ft), camp at Lake Helen (below The Heart) and then attempt to summit on Saturday morning (10440 ft to 14162 ft).
A New Doctor
Congrats are due to Doctor Luis de la Fuente. Ph.D. UCSF 2004!
Here we see Luis (middle) thinking while everyone else swills beer:
What exactly is he thinking? I think he is thinking “what happened to the left side of my body in this photo?”
