INTERESTING TIMES

I attended the May 12 meeting not really expecting much, but the program was excellent, both informative and amusing.  The speaker was Andrew Greenberg, and the subject was the Oregon Satellite Project and STEM Education.  Specifically he taught us a thing of two about space, orbits and nanosatellites.  I wanted to share just a few factoids that I got from him with you.

Andrew is adjunct faculty at PSU and helps students build rockets and satellites, in addition to his day job  He had recently done an OMSI science pub about the same subject, so he was well prepared and practiced. The OreSat mission is to use an actual satellite project to bring STEM (Science, Tech, Engineering and Math) to all Oregon high schools and to study cirrus clouds.

The Von Karman line is an arbitrary line dividing outer space from not space.  It is 100km above the surface of the earth.  Some balloons fly at 30km above the earth.  Cirrus clouds are the highest clouds and they are about 12km up.

There are three main layers of orbits, labelled LEO (low earth orbit), MEO (medium), and GEO (geostationary earth orbit).  Geostationary satellites have to be highest up and go the fastest to maintain their position relative to the surface of the planet.  Satellites cruise at around 200km from the earth, and they have to go really fast (8km/second or 17,500 miles per hour) to keep from falling back to the earth.  

NASA has a research satellite that was just launched May 5 this year.  It's the InSight mission and it intends to land on the surface of Mars.  The rocket that launched InSight also launched the first two CubeSats, which are small satellites that can be designed individually then connected together.  The high schoolers in Oregon are designing their own CubeSat, which NASA will launch!  They didn't expect to get awarded the opportunity to launch the satellite when they applied, but NASA called their bluff and now they're working on it.  All the software is open source.  The 2U (two unit) CubeSats from Oregon will get "hucked" from the space station into its orbit. It will stay aloft for 6-12 months, or maybe longer if they get lucky. 

The OreSat is scheduled to be deployed in fall 2019.  For the sake of the high schoolers, he's calling the OreSat a "400km selfie stick", because each time it flies over Oregon the high schoolers will be able to receive a packet of information from it, including a picture of their location.  

Then Andrew explained what he means when he says "Space Sucks".  Quite literally it sucks because it is a vacuum.  It speeds up the outgassing from any material that can, challenges welders to prevent leaks, and makes it tricky to keep anything at a reasonable temperature because it gets cold on the dark side and screaming hot in the sun.  The radiation from space does harm to transistors.  Solar cells are only ~30% efficient meaning it's not easy to power systems on satellites, and if they fail, they have to reboot without a mechanic coming to fix them.  "Watchdog systems" monitor the functions of the satellite and attempt to make things right before there is a system failure.

He also mentioned Planet Lab Doves, which are privately owned satellites that basically remap the earth's surface every day.  Exciting stuff.

Anyway, this talk was just a taste of what is happening.  Satellite technology is moving fast and the very first satellite put into orbit by anyone in the state of Oregon will be built by high school and college kids.  That's a fun way to approach STEM education.

I was registered and attempted to attend some of it. I have never been to this event before, and it was free for me because I work for the University that hosted it. The keynote talk was Friday night, and the speaker was intriguing and beautiful, but it was held in Radelet Hall which holds about 200 people, but has air exchange sufficient for about 20. When I went in the room was very warm already, and the talk was just beginning. The O2 content had to be low, because I immediately felt sleeply. Perhaps all those young brains can withstand a high CO2 environment for 2 hours to get the wisdom, but I cannot. The University should improve the ventilation systems for that space, as it has no windows to open and doors only on one side.  It is stuffy even with a small crowd.

I hung out near the back door long enough to hear the theme of Ola Obasi's talk which was Deconstructing Reductionism. The theme continued to resonate from the entire gathering. I went to Paul Bergner's talk because his was a name that I have long heard in herbalist circles. I had no conscious expectation, but his appearance surprised me. Most famous herbalists are gaunt and woodsy looking, and he had a pot belly on a stocky frame and a collared shirt that made him look like a gas station attendant. Bergner was perhaps a little surprised at the turnout, for he was in a room that held 40 and there were 60 of us in there. I was stationed near the door because that is my rule when inside the academic building which is an old masonry structure that is likely to crumble in a quake. They're planning to replace it but that's years out.

Bergner talked a bit about how science is applied to herbal medicine. "A scientific trial is like a serial killer" he said, "because it kills the complexity of the herb." He said that all botanical science falls into one of two groups, 1. pharmaceutical companies prospecting for useful constituents, and 2. supplement manufacturers shoring up the plausibility of their formulations. In other words, the profit motive is always at hand. When Big Pharma finds a useful constituent, they extract or synthesize it and sell it as a drug. They are always looking for another blockbuster drug. When supplement companies conduct their own studies, they are usually trying to prove that one of their products works for a particular condition. In both groups the tendency is to bury negative results and exaggerate positive ones in order to generate sales and profits. It is no wonder that herbalists in general have a bad attitude about science when it is said to be reductionistic and corrupt.

What I hope that the herbalists will integrate is the fact that each one of those studies that does give us a result--this plant has that constituent which has such and such an effect--gives us an evidence base upon which we can build a case for herbal medicine. Sure, the studies are not done for our benefit. But we can learn from that and build upon it, even while keeping close the traditional knowledge upon which the studies are built. If we know from all that corrupt research that Scutellaria baicalensis lowers inflammation in the liver and the brain, awesome! We can use it for those purposes, and extrapolate that it might help with inflammation systemically. We can also remember all the indications for that herb in ancient Chinese and western eclectic traditions, and extrapolate beyond what the science says as to what the herb in its fullness (and not just one constituent) might do.

We need both. We need the subjective and the objective. Science does not have to be reductionistic. I suppose there are scientists that will say that everything is reducible to chemistry and physics. But there are just as many scientists who will tell you that we just don't know everything that is out there, and there could be surprises. The fact that we just don't know is not a rational reason to believe in nonsense, but it is a reason to stay humble and reject reductionism. Everything is more complex than we know. When we find out one detail about something through the scientific process, we know one tiny piece in a very big puzzle. Nobody knows how complicated things are better than scientists.

Berner's talk was officially about herbal pairings (and triplets). To him this means pairs of herbs with complimentary actions which he can see no contraindications for giving together, and no situations in which he would want one and not the other. One of the pairs he mentioned was dandelion and Oregon grape, aka taraxacum and mahonia. In general his pairings have a function so that he can grab that mixture off the shelf and add it to a more complex formulation, saving time in the formulation process.

I tried to go to a couple of other lectures but ended up walking out. One speaker's voice was practically sedating--though I imagine some in his audience might have been hypnotized. Social justice is a major theme for this group, and there was a lot of talk about finding our roots so that we could extract ourselves from the white supremacy paradigm.  I imagine the goal would be to begin to operate as a conglomeration of cooperative and complimentary minorities; a modern civil society. I appreciate this message, and I do not need to sit through another 2 hour lecture in which someone recites their entire lineage and teaches us their family traditions. I am fully aware that there is great variety in human life. And I have been quite educted enough about the advantages I have in this society because of my pale skin tone and heterosexuality. Berate me no more, instead go out into the world and be awesome. Run for office and help us bring nuance back to government. Model your own kind of success.

After I left the lectures I went home and processed my own herbs. I learn more from handling the plants than I do from lay-level herbal lectures. It makes me appreciate the difference between CE and not.  At least continuing education classes allow for the possibility that we might actually talk about how to treat a condition, because we have licenses that allow us to practice medicine. I believe I need to offer an herbal class, and I'm sorting out a topic.  Probably herbs for the mind, perhaps herbs for the aging mind.  The kiddos won't be interested yet but I'm interested.

Today I finally got my updated living will / medical power of attorney updated, witnessed, and notarized, and I also officialized my first last will and testament.  My friends asked me if I was planning on leaving.  It's a good question to ask a person who is settling their affairs at my age, but no, in spite of the depressing state of affairs in the world, my life is good enough that I'm planning to stick around and see what happens next.   In my living will today I specified what I want done if I lose my mind (travel to a country where euthanasia is allowed for dementia--Switzerland or Nederlands allow it as of now), and also where I want my brain to go (for research purposes, to the Oregon Brain Bank of OHSU).  I'm excited and glad to have this done.  I've been meaning to do it and rewriting it for a decade now.

The real reason I was motivated to complete these documents at the age of 50 is that I can tell that I am losing cognitive function.  It shows up in many ways, and people routinely fight me on this observation, saying that I'm fine, it's normal aging, blah blah blah.  Let me just say that I used to be very smart, and I'm not any more, and I know the difference.  A minor example is that I make more mistakes in typing, for example I switch "their" for "they're" and vice versa.  This is a mistake that I used to find utterly mystifying, and now I am doing it.

The other day I updated my lifetime river log with the rivers I have run this year.  I've done 20 new rivers around Oregon this year!  But the shocker finding was that one day in July when I went paddling on the Lower Wind, I could not remember what had happened when I logged the day.  All I remembered at the time (a few days after the actual day when I logged it), was that I had planned to go paddling with Todd.  I did not remember where we went or what happened.

What happened that day was that I hit my head, again, and had short term memory loss as a result.  I have had many traumatic brain injuries over the years, from biking, skiing, and kayaking.  This is the reason that I want to donate my brain for research.  I suspect that my brain will prove that recreational sports participants can also suffer from CTE = chronic traumatic encephalopathy.  It's not just for football players anymore.

On that day I flipped over at the top of a rapid known as the Flume, and was battered on my head and shoulders as I floated through the rapid upside down.  I was afraid to try to roll up because getting in position to roll puts you in a more open and vulnerable position, so I "went turtle" which in this case simply means to tuck tightly under the boat and get my elbows in so nothing gets broken.   I rolled up at the bottom of the rapid and was dazed but otherwise OK.  And yes, for you who do not know me, I was wearing a top notch helmet.  There is no helmet that can protect your brain from the knocking it takes when your whole head is getting walloped around.

This was the third time I'd floated through that particular rapid upside down.  It is a steep, fast, shallow and rocky rapid....brutal, really.  One of my three upside down runs I didn't hit a thing.  Twice I've been beaten silly.  I vowed after this day to not run that rapid at low water anymore.  It's much easier at higher flows and that is the only time I will attempt it.  Unfortunately the portage is difficult and dangerous too... so I may not go on the Lower Wind as much anymore.  Too bad because I do love the waterfalls.

Something else happened that day.  I've thought of it many times since my memory of the day returned.  At the end of the Lower Wind run there are four major drops, three falls and one slide, not in that order. We'd run the first 12 foot falls without incident and were running the tallest single waterfall, about 18 feet vertical.  It's so high that you can't see if the person ahead of you made it, so we just wait a few seconds between boats and then go.  Todd went ahead of me and I waited probably eight seconds, then committed to the drop.  When I crested the horizon line and could see my landing zone at the foot of the falls, he was swimming in it.

He had plunged too deep in the hole below the drop, gotten caught and held, and wet exited from his kayak in the hole.  It took him a while to surface and start floating downstream.  When I saw him I was already mid-air and headed straight for him.  I was afraid that the bow of my kayak would plunge into the water and hit him in the abdomen, rupturing his organs and killing him. That didn't happen.  Thankfully I'd hit a good enough boof from the top that my bow skipped off the surface of the water and I went right over his head.  But the trauma of believing that I was about to kill Todd has not left me.  I am going to require a better signalling system for running blind drops from now on.  I need to know that the landing zone is clear.  We have had trouble at this drop before and still we are too casual about it.

HRS 707-734 Indecent exposure. (1) A person commits the offense of indecent exposure if, the person intentionally exposes the person's genitals to a person to whom the person is not married under circumstances in which the actor's conduct is likely to cause affront.

I needed to check because I keep wanting to take of my clothes.  It's so warm and humid--people go around, even hiking, wearing very little and carrying less.  I guess it doesn't matter what your body looks like, it's the conduct that matters.  This law does not deal with public sexuality the way the Oregon law does, which is to say you may be nude but not lewd.  Certainly flashing is lewd, but so is a whole lot more.  None of the laws mention lasciviousness.

Loved this video showing all my friends getting beat down. Everybody takes a turn at this level of whitewater. If you aren't willing to take a beating, you shouldn't be out there.

If you live and Portland and haven't picked up a copy of this month's Willamette Week (free news weekly, online here: http://www.wweek.com/portland/index.php), this issue is likely to get snapped up. They've named it the 420 Issue and it is all about the businesses and culture incurred by the recent legalization of cannabis in Washington and soon Oregon. What struck me initially is the amount of wordplay around the subject, and the generation of witty new phrases, words and hashtags that accompanies the surge in businesses and products containing cannabinoids. There is great excitement about the new availability and openness that comes with legalization.

I for one am OK with recreational and medical use. I think that the risks to society of adults using cannabinoids are fairly minimal. It certainly doesn't make people drive dangerously the way alcohol does. It does have a whole set of risks that aren't covered in this issue, and that really need to be kept high in our awareness as this drug becomes widely acceptable.

One risk that is coming into focus these days is of extreme overdoses. Back when folks just inhaled smoke, coughing stopped them from partaking too much. Vaporizers now make inhalation gentler and it is easy to overdose when consuming edibles. With either method you can't tell how much intoxicant is in there. With humans ingeniously extracting and concentrating the active principles, it could be very strong, or contaminated with solvents. With edibles the effect takes time to kick in. It is terribly easy to overdose for folks who are experimenting for the first time, and who have no tolerance at all.

The conventional media take on overdose--blaming it for many deaths and claiming that it is deadly--is probably overblown. It takes a massive amount of pot to kill, perhaps more than anybody is likely to actually reach because unlike opioids it is so unpleasant getting there. It is however a relative unknown: having been illegal for so long, we don't have scientific studies about overdose. We hardly have science to justify all the medical uses that have already been approved. We are going to find out now.

Another risk is incurred by the fact that edibles make the drug palatable to people who would never smoke it. It is tempting to children as candy. There is the danger that children, teens and early 20-somethings will enjoy sugary yummies containing cannabinoids and permanently alter their brain development. Later on in life there is still a brain changing effect, but in early life when the brain is still forming, the effect can be severe.

On top of these new risks due to the availability of edibles, there is the old risk of respiratory injuries resulting in sinusitis and bronchitis, and risk of more dangerous conditions like pneumonia and COPD. There is also the fact that marijuana increases heart rate significantly in most individuals. Folks who already have hypertension or heart palpitations might give themselves a heart attack.

I suppose my main message in the light of all this 420 excitement is BE CAUTIOUS and PROTECT YOUR CHILDREN because there is a lot we don't know. I believe in freedom and individual discretion as most Americans do, and I also know that people can be terribly foolish and injure themselves and others, especially when intoxicants are involved. I cannot protect the whole world from poor choices, but I do hope that this warning is heard widely. Please take care of each other and if you are going to play with the newly legalized products, start very small.

This state is so delightfully progressive it curls my toes. Much as I liked Kitzhaber, I think I am going to like our new governor Kate Brown more! She was sworn in yesterday. On Monday this week (when she was still Secretary of State) she made the announcement that the Independent Party of Oregon qualifies to be a MAJOR PARTY claiming as members more than 5% of registered voters as of the 2014 gubernatorial election. The total membership of the Independent Party as of 2/2/15 was 108,742, which is three voters over the minimum to become a major party. I suspect that with the publicity incurred by this landmark change, more people will change their voter registration from Dem or Rep to INDY.

This is great news in my book. I was out at the Imnaha river in spring and there is one of the first packs reported to have pups. I saw no sign of them. Now it sounds like most of the known Oregon packs have pups this year, even the newly discovered pack. Wild carnivores on the rise! We now have 53 wolves in Oregon. The ranchers hate it of course, but hopefully we can reach some equilibrium between livestock and canines that everyone can tolerate. I wonder if there might be some way to keep wild canines at bay that is as elegant as moving lights to keep away lions. Of course it's hard to protect your bovines when they're wandering far and wide...like those cows all along the Yampa. Need a wolf network up there too, keep the ranchers in line.
