Dry Slot

Time Passages IV
Posted by: Bogon, 6:37 PM GMT on February 13, 2012 +1
The Past

A year ago I posted a series of three loosely affiliated blogs, which shared the same title and which discussed different aspects of the same subject. The first one talked about two trees newly planted in my yard. Both trees are potentially very long-lived, but what is their life expectancy here on this suburban lot? How much time will they be granted? You'll be pleased to hear that those trees survived their first year. They've had a chance to set roots. This (and each subsequent) year's summer heat and drought should pose less difficulty for them. There was a third tree, an Eastern redbud, which did not fare so well. It got struck by lightning. Wife and I had to replace not only the fatally zapped sapling, but also the main circuit board in our television. Ouch!

The second blog presented a personal overview of time. How do we speak about time? How do we experience its passage? The third installment addressed cosmology: time considered on the largest possible scale.

So what brings me back again after all this, uh, time? Well, life goes on. We live and learn. This year I learned of some new developments in physics. I am not a physicist, but I try to understand how the world works. It is the same curiosity about the world that brings me to Weather Underground. I'm not a meteorologist, but I like to learn what I can about the weather.

As long as we're talking about the past, it might help to set the scene by reviewing some history. It has been nearly a century since Albert Einstein announced his theory of relativity. General relativity remains our best tested and most trusted model of the operation of the universe at the large scales observed by astronomers and cosmologists. The theory describes the interactions of space, time and gravity. Einstein's equations treat space-time as a continuum which warps and flexes in response to the presence of mass and energy. The word 'relativity' refers to the way the theory relates moving objects. Each object has its own point of view. According to the theory there is no fixed background or point of reference. If two spaceships pass in the night, the passengers on each one will tell a different tale about what they saw.

At the same time Einstein was developing relativity, other scientists were working on quantum theory. This theory accurately models the universe at the very small scale of subatomic particles. Quantum electrodynamics describes the forces of electricity and magnetism perfectly (insofar as we are able to measure). There are also good working theories for the forces responsible for radioactivity and nuclear power. The word 'quantum' refers to the discrete discontinuous appearance of nature when viewed at the smallest possible scales. It's like when you zoom in on your computer screen you see jaggies and dots, the individual picture elements, that make up the displayed image. According to quantum theory matter is comprised of a small number of elementary particles, each of which has a fixed mass. Energy is exchanged in little packets. Events proceed stepwise. From any point of view those events are likely to look a little blurry, because there are definite limits on how finely you can measure. The act of measurement affects the thing being measured.

Throughout the remainder of the 20th century these two theories were tested and applied. Both work very well within the domain for which they were designed. For any real-world situation, physicists are obliged to choose one theory or the other or compare the predictions of both. Nobody has figured out a way to combine the two. The theory of relativity does not extend to situations involving high energy and small scales, and there is no quantum theory of gravity. The math is too hard. The techniques developed within one theory break down when applied to the other.

The Present

For the last few days my mother has been battling an eye infection. Her doctor prescribed some ointment and an eye patch. Mom complains that, when she goes to pour a beverage, without proper depth perception she's liable to miss the cup and spill her drink on the counter.

Physicists, too, are tired of peering at the universe through one eye or the the other. They think their view would be a lot clearer with full stereoscopic vision. So when I say there is no quantum theory of gravity, I mean there is no complete theory. The last ninety years have not been wasted. People are working on a variety of approaches. Some start with relativity and try to quantize it. Some start with quantum theory and try to develop a background-independent version which includes the graviton.

One approach that gets a lot of press these days is string theory. The basic idea behind string theory is that elementary particles should not be portrayed as dimensionless points. They are granted a finite size, which makes some of the mathematics more tractable. I say 'some' of the math; there is much more to string theory that is very hairy indeed. String theorists propose a group of elementary particles that have not been detected and postulate several extra spatial dimensions beyond the three that we observe. In support of their theories they offer weak circular arguments such as the anthropic principle. Whenever reality threatens to contradict the theory, they spawn a new version. In fact there are a zillion string theories with no obvious way of picking a winner.

From my point of view they are all losers. String theory is a monster that devours talented young mathematicians. It sucks up lifetimes and hefty research budgets and leaves nothing to show for them. It provides a convincing model for how to parley government grants into academic careers, but it has done nothing to shed light on how the physical universe operates. There are no verifiable predictions of string theory.

There are numerous competing theories that seem more promising. There's Roger Penrose with his spin foam and tensors. There's Lee Smolin, who champions a theory called loop quantum gravity. These guys are results-oriented. Unlike string theorists, they manage to refrain from wandering off into fanciful realms of elegant mathematical complication. They'll be content if they can explain known particles in three dimensions.

Loop quantum gravity theory asserts that space-time is quantized, i. e. there is some minimal unit of volume out of which space is constructed. Thus, on a very small scale it would be possible to view space as a kind of fluctuating grid. An elementary particle would have a finite size. It could be no smaller than a block in the grid. The particle would be represented as a set of properties (e. g. quantum numbers) assigned to some region of the grid. Gravity appears as curves and waves in the grid lines.

Here are links to two presentations from Perimeter Institute in Canada. You can watch Renate Loll describe causal dynamical triangulation, and/or view Fay Dowker as she expounds on the theory of causal sets. You may have noticed that the last two theories include the word 'causal' in their titles. That's where time enters the picture: the sequence of cause and effect. In addition to quantizing space, these theories add the notion that all the little grid lines must be aligned timewise. The arrow of time is built in from the start rather than being sought as an emergent property. That turns out to be a significant innovation. Calculations become easier, and believable results follow. If you listen to the videos, you'll hear how several lines of evidence from thermodynamics, information theory, black hole theory, astronomy and cosmology converge to indicate that these people may be on the right track.

The advantage of such theories is that they can reproduce some of the observed properties of three-dimensional space (plus time) with a minimal set of assumptions. A disadvantage is that each theory only provides an incomplete and unwieldy model. It is not an equation. It is an algorithm for simulating space-time. It runs on a computer much like one of the weather models here at WU.

The Future

None of these theories is ready for prime time. Progress is slow, because the problems are hard. Only in hindsight is it clear what questions to ask in order to get the right answers. Will it be easier to work from the top down by quantizing relativity? Or will the bottom up approach, adding the force of gravity to an existing quantum theory, yield the prize? Will it become possible to translate a computer-driven algorithmic model into a concise set of equations? Will string theory ever be good for something practical?

The goal of all this theorizing is perfect binocular vision. Physicists want a Theory of Everything. It doesn't mean that they'll immediately be able to solve all problems and write down all possible knowledge in a book. It means that we humans will finally have a single unified theory that accounts for all known particles and forces. Far from being an end to science, it will make a great beginning for whatever comes next.

That's a great looking tree, BF.

There is a corridor of I-40 from Burlington to somewhere west of Winston-Salem that passes a bunch of redbuds. Probably east toward Raleigh, too. I drove the road west last week.

When the redbuds crap out, the dogwoods take over. That's our state tree.

Add: oops, I meant state flower. State tree is the pine. The Pine State (hence 'Tarheel').



Dogwood is the state tree of Virginia. That state line lies a hard day's walk north of here.

When was your Dogwood Flower chosen?
Pacific Dogwood - Provincial Flower
The Pacific dogwood (Cornus nuttallii) was adopted in 1956 as British Columbia's floral emblem. The Pacific dogwood is a tree that grows six to eight metres high and flowers in April and May. In the autumn it is conspicuous for its cluster of bright red berries and brilliant foliage.
Eight meters! One in my yard was that high 30 years ago.
Last year the trees (we have four or five in different sizes) flowered in an odd fashion. One would have blooms and another would be fruiting. Blooming was not restricted to April/May. We noticed the oddity but made no notes of the dates.

ycd - Dogwoods should start blooming any second now. :o) I reckon they're waiting for redbuds to finish up.

According to these people dogwood was chosen as the state flower in 1941, which was ten years before my time.

I have seen the Pacific dogwood. It grows bigger than the eastern type. The trees here look similar, but they seldom reach six meters. They don't live long compared to, say, oak or hickory.

Dogwoods here are blooming, while the redbuds are still going strong! Don't see that very often!

The dogwood trees are starting to light up here, too. And like you say, the redbuds and cherries are still mixing it up.

Spring is putting a move on. The native trees are leafing out now. Every day brings a new look and new surprises.

A thunderstorm passed tonight as we were having dinner. It came courtesy of the big upper level low that has been drifting slowly across the continent. The forecast gives us a 50% chance for more showers tomorrow. Monday promises a return to sunshine.

Ylee, Kansas was too much for the overachieving NC State Wolfpack to handle. They may be too much for UNC's injury-ridden lineup, too. We'll see.

Wow. Those dogwoods are beautiful. I've only ever seen them in Mississippi, at the end of their bloom. I know we have some here in east Texas, but they're understory trees and I think you have to be in particular parts of east Texas to even see them. I can't remember ever seeing them here in Houston. Just gorgeous.

I take it there's no North Carolina in the final four. And I guess there are two Kentucky schools? If you were from Kentucky, how would you know who to root for? I guess it's like UT and A&M.

I just finished reading a great book review I think you'll enjoy - might enjoy the book being reviewed, too. You can find it here, under the title "Science on a Rampage".


I believe I might even have to give it a read. That combination of Schrödinger and William Blake has to be a winner. ;)

So...

   I've been out of the loop for a few days. Wife and I absconded to the beach.



The mini-vacation was part of Wife's extended birthday event. This birthday comes with a zero appended, her personal odometer rolling over, and she's been milking it for all it's worth. Can't say that I blame her. The ongoing festivity has given me a chance to reprise my own birthday celebration, which (as usual) was rudely interrupted by Christmas.

Today I ran across this link and thought I would pass it along. Wouldn't be surprised if other bloggers have linked the same story. Like I say, I've been away from the console. It's going to take me a few days to catch up with what's been going on around WUville.



shoreacres, that's right, UNC got eliminated. That was the last ACC school left in the dance. With the Tarheels' departure, my interest in the NCAA tournament drops from personal to purely intellectual. I don't feel any obligation to watch either semifinal game. I may, but I would be perfectly happy to read the results in the newspaper.

That is an interesting book review, and the book would probably make good reading. I think I'll start by finding out what the wiki has to say about William Blake. I've read "Tiger, tiger burning bright", but I don't know much about the poet.

My favorite non-mainstream theory was postulated by surfer dude Garett Lisi. His theory is not necessarily all hogwash. Lisi knows his mathematics, and he knows a good deal about physics. Like string theory Lisi's theory is based on a beautiful mathematical object. Unlike string theorists, Lisi freely admits that's he's just playing around with the math to see where it leads. That approach garnered howls of derision from the likes of Luboš Motl. As far as I'm concerned, Lisi stands as good a chance of being proven right as any highly touted string theorist.

Ylee - I'm sure that Duke and Carolina have met before in an NCAA tournament. It happened for the same reason that Ohio State had to defeat Cincinnati and that Kentucky now faces Louisville. It you have four or five contenders from the same state or conference, there's no way to lay out the bracket to prevent their eventual collision. The best outcome is when the meeting comes late in the tournament, so that both teams enjoy the maximum opportunity to knock out the other competition before setting to work on each other.

I apologize for being somewhat irregular lately. There has been a lot of coming and going around here. I'll deploy that as my flimsy excuse for why I haven't updated my blog header for forty days and forty nights... and then some.

Last night Wife and I went to see Pink Martini in Durham. Now I'm back. It turns out that Pink Martini have a thing or two to say about coming and going.

Took some doing, but I'm finally caught up on your doings since I dropped out a couple of weeks ago. You've been to the seashore and taken some very nice pics, and I really love that camellia of yours.

Followed the link in #111 for some interesting reading about climate change from a Republican perspective. Maybe there is hope there. I don't really care about the noisy minorities on right and left, if the moderates from both sides get their heads on straight, progress may yet happen.

Proserpina, thanks for stopping by with an April greeting (and no fooling).

BriarCraft, great to see you up and around!

Part of Wife's birthday celebration included a visit from two of her friends, who brought live plants as a gift. In the trunk of their car they hauled three camellias and a climbing hydrangea from somewhere north of Atlanta, Georgia.

Wife got a nice birthday present, but I inherited the chore of planting all those shrubs.

Bogon, you don't expect the wife to plant her shrubs on her birthday, do you? :)

Of course, I've recieved gifts with "some assembly required", but usually putting stuff together is more fun than digging a hole!

Hey, Ylee. Actually Wife's birthday was over a week ago, but no, I'm pretty much resigned to my role as the family's principal surviving hole digger.

The good news is that we've been getting some rain, and the ground is soft. The bad news is that we've had something going on every dang day, and it's been hard to establish a rhythm.

Today could be the day, though. Not much on the schedule (read: I'm running out of excuses :o).

Woof! I didn't have to go looking. The excuse has come to me.

Last night a warm front squiggled across the area dragging light rain and summer behind it. At ten AM the thermometer registers 70°, but don't let that fool you. It's like a turkish bath out there in the sun.

Well, shucks, seems like the bill has come due for all those February flowers. By April it's already too hot for comfort. I reckon I'm going to have to wait for the sun to shift over to the other side of the sky before I go digging. Hopefully the neighbor's oaks have leafed out enough to make some shade. Maybe there'll be a breeze later.

Or maybe that front will squiggle back the other way. It wasn't bad on the north side.

Half an inch of rain yesterday didn't help much with the planting. When the rain ended, it was cooler, and there was enough daylight left to get two camellias in the ground. That leaves the hydrangeas.

The regular hydrangea shouldn't present a problem. Wife is happy with the spot where I set the plant down. The vine version needs somewhere to climb. Wife and I have been looking over the few mature trees on our suburban lot. There is one leading candidate based on the tree's age, health and location. I need to figure out where to dig the hole, a) with respect to the tree's roots, which I don't want to damage, and b) relative to available light, soil quality, drainage and other nearby plants and obstacles. Maybe I'll get lucky, and all of those considerations will converge on the same spot.

Still rainy today. There's another upper level low drifting this way. I reckon it has to clear the area before normal weather activity can resume.

Meanwhile the temperature is near sixty, with cooler air on tap for the weekend. That's more like it.

I've never been trained by a shaman, ycd. Linear optimization would be more my style. In practice I just went out to look at the tree, picked a likely spot and started probing the ground. The shovel slid in easier than I expected.

There were a lot of roots. I cut through the little ones and tried not to skin up the big ones. I found two shards of pottery and several earthworms (or pieces thereof). An old rusty pipe limited the excavation on one side. I have no idea why the pipe was there. I'm pretty sure it has nothing to do with my household utilities, because I've had those marked out for me before. I left the pipe alone; I'm not interested in backyard archaeology — not today, anyhow.

It took a while, because I was being careful, but eventually I got a hole big enough to contain the root ball. I put the worms back in before I covered it up, applied water and mulch.

The climbing hydrangea came with a little bamboo tripod to hold it up. I'm wondering if I should leave that on there and wait for the vine to grow to the tree, or whether it would be better to go ahead and fasten the plant to the tree now. Hmmm, maybe I'll call up the folks who gave it to us and find out what they have to say.

Hi Bogon,
Guess it's been a while since I stopped in. Looks like you been enjoyin' life.

Gorgeous dogwood. One time had the privilege of taking a road trip from Quantico through NC and on down through the deep south to FL panhandle. Anyway, it was April and the dogwood trees were in bloom. Will never forget the sight.

Enjoyed the beach photos. I am puzzling over the birds on the beach because they look too long-legged to be gulls and too plump to be sandpipers. lol

Maybe some rain headed toward your wife's birthday plants this eve. That climbing hydrangea's really something! Happy belated birthday to her.

Bogon: I think we called it "Linear Algebra" or something. I've probably got the text book somewhere.
One of the goofiest courses I ever passed.
Come to think: "Mystery Math" with what's his name?
Davinski was even more confusing.
Then there was "Continuum Physics" when what I wanted was a course in "Quantum Physics".
T'anks God those days are behind me.
But I'm still learnin' here.

Barefoot - It has been a while since the conversation you quoted. The redbuds have faded and the dogwoods and azaleas have taken over. I've been noticing some really fine looking azaleas this week.

As for sandpipers, I admit to being essentially clueless. At the beach I saw two kinds of birds with the same basic planform. The smaller kind flocked and scurried along the edge of the water. The middle picture in comment 111 shows a flock silhouetted at sunrise. Here's a better picture. My best guess at a name for these is sanderling.



The larger kind was more dignified. With its longer legs it didn't have to run fast. It was also more solitary. I saw them in pairs, but never in flocks. The photo I labeled "Sandpiper" is of one of the big ones. My bird book was no help, because it listed too many kinds of similar birds for me to keep sorted. I gave up.



Never did figure out what those black birds flying in V-formation were, either. If this were the west coast I might call them shearwater. The closest thing I could find in the east is a cormorant.



We are having rain again this evening. It should help settle the plants. Settles me, too, because I won't have to worry about watering them.

ycd - To live is to learn. Learning is easy for me, because I've already forgotten a whole lot of what I used to think I knew. ~:o]

Thanks for your warm Easter greetings, seflagamma, juslivn and Skyepony.

In the past I have referred to the little valley where Mom lives as a "meteorologically disadvantaged area". Often, in winter, it snows here, when there is no snow a few miles away. At other times of the year it seems to be cloudy here, while the sun shines elsewhere. This weekend, since Wife and I arrived, the weather has been as delightful as one could imagine for early April.

In the valley the dogwoods are blooming and the trees are turning greener every day. On the ridge tops the first flush of spring is just starting to soften the drab gray of winter. You can see the color change rising up the mountains.

I usually phone Mom at 0800 hours on Sunday mornings. I was reading about your visit and: Ooops! At least I left a message. She makes sure she gets out for a walk on nice days and the Co Housing she lives in will likely have an Easter Egg Hunt because there are numerous families with small children there. She is still involved with organizing these events.
Our Dogwood are budding and it will be interesting to see how they react to much more sun from the clearing we did. If they thrive they will certainly dominate the yard 'cause before they were buried and shaded by the bigger evergreens.

I see you've headed for the hills - or perhaps you're heading home now. In any event, I hope the visit was fine, the weather good and chocolate abundant.

The Geek Bunny wasn't sure where to find you, so he asked me to drop this off for you to tuck into your basket. Happy Easter!

ycd - I'm happy to hear that I had a part in facilitating communications with your mom, even if it was unintentional on my part, and even if it was somewhat belated, and even if it ended up on her answering machine. I'm always happy to do my part to make the world a better place. :o)

Last year we cut down four Leyland cypress trees in front of our home. They had been planted too close to the wall. As they continued to grow they began to rub against the side of the building when it was windy, and we became concerned that they would eventually cause damage to the roof or siding.

The trees were five or six meters tall, so they left a big hole in the landscape when they were gone. We're still working on filling in the blanks. Plants by the front porch that were formerly shaded seem to like the extra sunlight. They're looking lush this spring.

Prose,
I wanted to
Compose for you
A little poem.
But wouldn't cha know,

My balky mind
Cannot find
The proper rhyme
Half the time.

shore - Wife returned home today. I'll stick around another day or two.

Thanks for thinking of me at Easter time. That egg sure is cute. Don't think I would want to be the funny bunny who laid it. Ow!

Mmm, had some nifty chocolate cake at Grove Park Inn yesterday. Can't say that I necessarily associate Easter with chocolate, though. I think of multicolored sugary eggs nestled in in a basket full of shredded green paper fake grass.

As the weather warms my thoughts turn toward ice cream. Chocolate ice cream will always be a favorite, but these little sandwiches are awesome!

Lots of special weather statements on the NWS forecast for Mom's location today. There is a freeze watch, a fire weather watch, a special weather statement (fire danger), and a hazardous weather outlook (fire danger until 8:00 PM, fire weather watch for low humidity and high winds tomorrow).

The fire danger thing is interesting, because I just spent the day burning brush behind Mom's barn next to the creek. There was no fire warning in effect when I started the fire this morning. It is noticeably dry and windy now, but now I'm done.

Long term veterans of this blog may remember that the last time I ventured down to the brush pile I got a bad case of poison ivy. I think there is a high probability of contact with the pernicious weed this time, though I have been as careful as I know how. No itching so far. Wish me luck.

Hey Bogon!

Fire weather here in south central FL as well. Humidity down to 25 percent this afternoon.

Get yourself a Tyvek suit like pesticide applicators use, and maybe a mask if you are extra sensitive before messing about with the ivy.

Take care friend.

Glad the burning went well. It's so smokey here. Hope you didn't burn any poison ivy.

I can attest to how good the food at The Grove Park Inn is..I once took a lover that was a chef there.

Hey, Rob!

That sounds like a good tip, if I can figure out where to get the Tyvek suit. That could be useful even if all I want to do is keep my clothes clean.

Hmm, is Tyvek flammable? I believe I might want to test that before I wear it to a bonfire.

Today I wore a hat, gloves, jeans and long sleeves. As soon as I got back to the house I put it all in the washing machine and took a shower. So far so good.

I'm still worried about my boots and belt, because they're not washable. I have other shoes I can wear until I get home. Then I reckon I'll break out the saddle soap.

Skye - I was mostly burning fallen tree limbs, stuff too small to be useful for lumber or firewood.

If any poison ivy got burned, it was unintentional. I could see poison ivy in the area. I know it grows there. I tried to avoid it, but when you're working you can't watch every second.

I would prefer to do this chore during the winter when the plant is dormant, but that schedule didn't work out this time. Besides, it was winter when I got poisoned before. I grabbed a bare stem. Without the telltale triple leaflets I didn't recognize it. Didn't realize I had been exposed until it was too late.

So... you knew (in the Biblical sense) a chef who worked at the Grove Park Inn? I'm thinking that on a weather blog that may be too much information. :oD

Class A Flammability rating.
Might melt if it got hot enough, but difficult to burn I would think.

Dig around, you've probably got one of those Tyvek floppy or CD sleeves somewhere to conduct a test with.

I know the Ag industry uses them here and they are also used in some mechanical/construction applications. An Ag supply place that sells chemicals probably has them. Home Depot might, I've never asked.

Used to carry them around in the truck in case I had to do something messy. Handy to have.

Maintenence crews here uses Tyvek jumpsuits for dirty jobs, and they can be arout 1400F aluminum melters, so they are somewhat flame retardant and heat resistant.

For better protection, do you know any firefighters? They may give you some old stuff that needed replacing.

Thanks for the advice, guys. I was dressed in cotton, which is slow (but not impossible) to burn. I would mainly worry about synthetic fabrics that might sputter and melt if they caught fire. That would be bad.

Looking from another angle, cotton is comfortable. It breathes. I had access to pockets, i. e. a hanky, when the smoke or pollen got to me. I'm not sure I would like being zipped up inside one of those suits, especially for hot work.

Okay, I need to get out of here and drive two hundred miles back home. See you on the other end.

I enjoyed the info about the climbing hydrangea. According to what I read in the link, they should grow well here, yet I've never seen one in a nursery or in any garden around here. I'm intrigued. Gonna have to do some more investigating....

Did you know it's possible to take pride in hole digging? I grew up well-acquainted with my dad's hole-digging expertise, but thought that was just his thing. Then I met DH, who digs precisely plum vertical sided holes with perfectly square corners. He is so proud of his holes that he gets insulted when I insist on roughing up the sides and loosening the soil in the bottom.

From my sometimes miserable interactions with poison oak, I'd say you did the very best you could to avoid contamination. Smoke carries the volatile oils better than just about anything, but prompt and thorough washing immediately after is usually effective. Hope that's the case for you. Seems like Tyvek suits might be very sweaty, which could be a bad thing.

Safe travels..

We always have to deal with our Poison Ivy up there at the wrong time of year too. Twice now I've taken the husband to get a shot for getting in it so bad. The worse was hugging a tree covered in it, in the dark putting up a hammock.

& sorry~ such a place of elegance & good times.

Thanks, Rob. Ah, the comforts of home — I get tired of the cramped little keyboard and mouse pad on Mom's laptop.

BriarCraft, I didn't know about climbing hydrangea, either. The folks who found it for us are very much into horticulture. They recommended that I detach the plant from the bamboo pyramid with which it was shipped and tie it to the tree where I want it to grow. That made sense, when I thought about it.

One thing I learned is that the stems of the hydrangea are woody and stiff. I gave up trying to bend the plant over to the tree for fear of breaking it. I tied it loosely to the trunk for support, but it will have to grow to the tree on its own. If I had realized that before I planted it, I might have tried to tilt it more toward the tree. Live and learn.

That's funny about DH and the square holes. I'm sure the plant doesn't care about the shape of the hole, as long as its roots are comfortable. After all, the hole goes away when you refill it.

I've had no ill effects from poison ivy. Its possible that I've been overreacting; I figured better safe than sorry. I'm allergic to urushiol but not extremely so. Normally, it's not that big a deal, but normally I don't have to work around the stuff.

I must be getting old and out of shape, because I got fatigued rapidly doing this unaccustomed chore. I made a lot of progress, but I could have done more, if I'd had the vim. As you say, the Tyvek suit might make it even harder to keep working.

Skye, yep, that's the main risk from poison ivy, that you'll tangle with it without realizing it. Most people who are allergic learn to recognize the leaves and black hairy vine running up a tree. Sadly that doesn't work for children or for people floundering around in the dark.

As I was typing this comment I got a call from Mom, who informs me that the Grove Park Inn has been sold.

In addition to pictures of Uma Thurman, I also ran across this article, which describes possible approaches to eradicating poison ivy. They also have a better picture of a mature vine than the page I linked in the last comment.

Hey man,
just checking to see that you made it home alright.
Took me a while to get to the point that I can switch back and forth from the desktop to the laptop without having a fit. Still feels cramped.

Rob - Yep, home safe and sound since Tuesday night. Had a dental appointment Wednesday. Made time for a disc golf appointment yesterday. :o) Need to spend some quality time with the lawn mower soon, though the dry weather is generating welcome slack in that department.

The keyboard on Mom's laptop is not bad — for a laptop. It is cramped and flat but usable. I can never remember where the cursor keys, Insert, Delete etc. are. The screen is sharp and clear, but it fits the new 16x9 aspect ratio, which is designed for media rather than for blogging. The worst feature is the touchpad. It has only two buttons and no scroll wheel. That last item is the worst. The wide screen guarantees that you'll be doing a lot of vertical scrolling, which you can only do the old-fashioned way, by clicking and dragging a scrollbar. Clicking and dragging with a touchpad is not the most natural and fulfilling task in the world.

I know, gripe, gripe, gripe. If I used the laptop a lot I could probably get more comfortable with it. For instance, the touchpad supports gesturing, which might ease some of my woes, if only I could be bothered to learn how. As it is, the first thing I did was to turn that feature off, because it kept doing things that I did not expect or understand. It got in the way.

I could pack my favorite trackball each time I visit Mom, and plug it into a USB port. But then I would need a desk on which to set the trackball. That would sort of miss the whole point of having a laptop, which frees you to use the machine anywhere. Gripe, gripe, gripe. :o<

No, Ylee, Batman got Poison Ivy. So, when I went googling for pictures of poison ivy, I found Uma Thurman in addition to Toxicodendron. Besides Ms. Thurman, there were various other role-players and conventioneers scantily clad in leaves of green. There is a fun side to blogging after all. :oD

Good Morning Bogon ~

Glad you had a safe round trip to your Mother's residence. Hope that she's doing better than her laptop seems to be. I'm curious to know if she still uses it, herself, despite some of its obvious intricacies? If so, I'm duly impressed!

I know what you mean about the features of a laptop versus a desktop. I'm more comfortable with the latter and would feel quite annoyed without a scroll-wheeled mouse. I'm definitely an old creature of habit.

Similar to the dryness of your area, Massachusetts has been going in and out of a critical red-flagged mode and, therefore, parts have experienced the occasional outbreak of dangerous brushfires. Fortunately, hubby and I have escaped these threats, in spite of living in a wooded area. There's no real sign of any plentiful rainfall in sight despite recent and upcoming periodic sprinklings.

When there's time, we're soon going to have to start up the ole power mower, too, as the mixture of overgrown grass and ugly dandelions is overtaking our yard. YUK! At least, better temps of 70's are expected over this weekend with sunny and mid-80's on Monday. That should give us the impetus to get off our duffs to either get mowing or break open a new jar of barbeque sauce. Right now, the last thought seems more appealing. LOL!

Have a pleasant and safe Friday the 13th!
