Imaginary Numbers in Everyday Life

Having studied imaginary numbers and their benefits in simplifying calculations in both mathematics and physics, it's obvious that they have a wider use.

In developments that could rock the traditional fields of accountancy and statistics, my colleagues and I have been exploring their application in both of these areas.

For instance, in my personal accounts, I now regard bills that are unjustly levied as being in imaginary dollars rather than real dollars. For instance, a parking fine that I don't agree with (i.e. all of them) would be classified as imaginary, and I would not in reality have to pay it. Similarly, a Lotto win by members of my family is also regarded as imaginary because the proceeds are not available for spending; instead they are instantaneously ploughed straight into buying more tickets.

Making Use of Dirty Undies

Where should you hide valuables at home? Assuming you don't have a safe but you do own some jewellery, collectibles, or antiques, what unexpected hiding place would confound a burglar? Firstly I must note that I have nothing of interest myself, so anyone planning a raid on Fortress Lewk is wasting their time. And in any case, my cats are liable to vomit on strangers due to their nerves, so it's not worth venturing inside unless you fancy being covered in salmon chunks.

Diversion is one strategy that may not save you, but could at least slow down any intruder and give them something to think about. If you have a desk with lockable drawers, or a lockable filing cabinet then people will waste time trying to open them. Another option would be to leave a note attached to the fridge referring to a non-existent safe (eg "Remember to check safe buried under backyard") or perhaps a receipt mentioning a fake rock containing a key could be left lying around.

The number one place that malcreants look is the bedroom, so avoid using a wardrobe, a dresser or mattress. But should you order some skidmarked undies, you can feel reasonably confident that nobody will venture inside.

 More creative safes can be found here.

The kitchen is the second most obvious hiding place; in a pantry, in a cutlery draw or even in the fridge. And should you cleverly put something valuable inside a box of cereal or in a biscuit tin, imagine a helpful partner  reading the expiry date on the packet and send it binward. Now who's too clever for their own good?

My favourite idea would be to use the traditional hollowed-out book trick. Should your house be bulging under the weight and wisdom of thousands of books, why not stick your family heirloom lucky diamonds and pearls inside a randomly chosen tome. Only an obsessive-compulsive thief would bother looking inside all 20 volumes of the Encyclopaedia Britannica, so sacrifice volume 15 (Perspiration - Rumpy-Pumpy) and cut out the insides to make the perfect hiding place.

Do you have any better ideas?

Golden Rays are Clichéd

Overlooking the Pinnacles last Friday. Or perhaps the plains of the Serengeti. You decide.

Aussie Stonehenge

Visiting the Pinnacles Desert  north of Perth this weekend, I arrived just in time to participate in the Druid Ceremony of Sunset. We sacrificed a bottle of champagne and some olives and a couple of small children and in exchange, the earth spirits granted us a victory by Claremont in the upcoming Grand Final. If it doesn't work, I'm going to ask for a refund - the champagne was very pricey.

The sacrificial child at right was lured here by a trail of lollies

Squirrel Sabotage

How unlucky am I? Having set up at Glacier Point for a beautiful picture of Yosemite's Half Dome, a squirrel saboteur popped up in the middle of the frame. Now I have no choice but to attempt to Photoshop him or her out.

The Fatal Metaphor

Is it a bad sign that the novel you've chosen to read has an unintelligible title? Having just enjoyed The Fatal Revenant by Stephen R. Donaldson, the eighth in his Chronicles of Thomas Covenant, the Unbeliever, I'm still at a loss to understand exactly what transposed in several passages due to the archaic and obscure language. Without reverting to a dictionary every few minutes, some sections will remain forever mysterious to me. For instance, can someone translate this line for me:

       Limned in argence, they performed a florid masque.

I am familiar with the individual words, but they're combined in an unusual way.

And these words are from a single chapter: orogeny, surquedrey, glode, chthonic, lambent, theurgy.  This esotericism may deter some readers, but I adore it. Rather than using prosaic and mundane language, his creative use of obscure words adds to the atmosphere of awe and splendour and intrigue. Even though it's a minor riddle to be unravelled, it's enriching and rewarding.

And no, I never worked out who or what the Fatal Revenant was. They could have at least sketched one on the front cover as a clue.

Descent into Redness

Surely this fantastical landscape can't be real. It must be a dreamland.

A trail of trekkers are heading into the main ampitheatre of Bryce Canyon, enticed by the thrill of discovery, curious to find what's around the next corner. But having headed enthusiastically for an hour down that same enticing path, I know that in the heat of the day, the suffering involved in walking up and out again can almost but not quite extinguish the joy.

Woof Woof

Can someone please translate this message for canines? I saw it in Bryce Canyon National Park in Utah and have been puzzled ever since.

Facing the Fearsome US Border Protection

One reason I flew into Canada rather than the US was to avoid the unpleasant American border protection agents, those rude and humourless and overweight souls who spend their hours hassling passengers, scanning  babies for concealed bombs, interrogating anyone who might have accidentally downloaded a copyrighted MP3 or movie, or might have radical vegetarian pamphlets concealed somewhere. And arriving at Vancouver airport, the Canuck equivalents were invariably over-the-top polite and friendly, so I was pleased with my decision.

And so with trepidation I neared the US border after leaving the Canadian Rockies and heading south into Montana and Glacier National Park. Expecting a grilling after reading horror stories from other travellers who had been detained for trivial incidents, or for joking in poor taste, I tidied the rental car so that it looked respectable and not in need of a rummage around, and was prepared for an interrogation. Arriving in Chief Mountain crossing, at the top of an achingly beautiful mountain pass, the signs were ominous as five stocky agents were hanging around, guns holstered, shiny Homeland Security badges on shirts, waiting to pounce. But when they started talking they were friendly, and all fears evaporated. They had a quick look inside the car and had no further interest, telling me to park and head inside the office to fill out a form and show my passport. Inside was an even friendlier bloke at a desk who handed over an immigration card, a German one. When this was queried, his colleague said "Willkommen" and swapped it for an English one. After completing the card, his checking of my passport was interrupted by his colleague in the back office who had found something funny on YouTube. The desk officer excused himself and went back to watch the video, then returned with a big grin to finish his processing. Then I went on my way, so pleased that I had made it into the US without any fuss, and also happy to see a bunch of blokes with guns on a remote mountain having such a fun time.

Underneath the Aquarium

At the California Academy of Sciences in San Francisco, you can walk under one of the aquariums. Mmmm fish.

Unusual Intersections II

Two more types of intersections that I never figured out in the US and Canada were flashing green traffic lights, and flashing amber lights.

Having no idea of their significance, I had to quickly decide how to handle these junctions. My approach was to be ultra-cautious and to assume that the flashing indicated danger, and so I sped up and zoomed through as fast as possible in order to leave the area a toute vitesse. Luckily there was no cross-traffic at the time, and I survived unscathed, but had anyone on a side street taken my approach, I would have ended up somewhat scathed.

Unusual Intersections I

What's an All-Way Stop? Yep, that's right, it's a common type of road intersection in the US, where two roads of similar importance meet without traffic lights. And it's incredibly puzzling if you're from the land of roundabouts. The idea is that everyone stops when they approach, and then the vehicles pass through in order of arrival. Fair enough, that sounds easy enough, but imagine the case where there are two or three cars queued up in each direction. You have remember the order of arrival of those ten or so cars, and who arrived earlier than you. In practice, people politely and cautiously take turns, after making eye contact with other drivers. It does make you feel part of the community, meeting the locals in this way, but it's certainly not as simple as whizzing through a roundabout.

Zion National Perk

On a sweltering day in Zion National Park, the ideal hiking destination is a waterfall. Being midsummer in the desert, the water has almost gone, but it's still refreshingly cool. But don't touch the water, it's contaminated with giardia.

Tacky?

The Paris Hotel in Vegas is so over the top it's beyond tacky, but I still love it. Here's a view of it from the outside, on the strip. To have the audacity to replicate Paris in the desert, but without getting advice from a Francophone on how to at least spell a few words of French correctly, is somewhat cocky. On the inside of the door of my room was a notice asking guests to observe a few rules, and it ended with "please" spelt "si vous plait".

Canyon Fatigue

At Canyonlands National Park in Utah, I exceeded my brain's capacity for storing views of canyons, and my body shut down. Eventually after freeing up space by deleting memories of calculus lectures at university, I was able to reboot and resume my tourism.

Incidentally, this is the location of the gruesome story of Aron Ralston who had his arm trapped by a falling boulder nearby, and after 127 hours, escaped by cutting it off with a knife. Luckily I didn't suffer the same fate, although I did crush my finger slightly when closing the glovebox of my car, so I can certainly understand what he went through.

Relaxed Driving

Being used to aggressive and sloppy Perth drivers, it was a pleasure to find friendly drivers in the US and Canada being the norm. Even in busy cities such as Vancouver and Seattle, I found tailgating rare, and there was little impatience. By contrast, this morning's ten minute commute to work featured two occasions when I wanted to change lanes but was blocked by a car in another lane who closed the gap immediately. On my recent trip I never had difficulty in changing lanes. And in the entire 12,500km, I never had to emergency brake because someone pulled out in front of me whereas I did that twice yesterday on a quiet Sunday afternoon in Perth.

Here I get the impression that everyone the roads is my enemy, and we're all competing to get to our destination first. Over there, I felt warm friendly feelings from fellow road-users. In Australia, when I see I truck approaching from behind, getting larger and larger in the rear-view mirror, I dread how close they get, and the pressure they put on you to speed up or pull-over to let them past. In Canada and the US, the trucks would stay a sensible distance behind and wait patiently for a chance to pass. I do miss being over there - it was so easy to burn off all the competition at the lights, even in my sluggish Corolla.

My Own Rainy Idaho

Driving from Wyoming to Utah I spent precisely three hours and eighteen minutes in Idaho, and every single minute it rained or threatened to. I entered the state in a car with hundreds of insect corpses splattered on the front, with muddy marks along the sides, and with grimy windows. Leaving the state, the car was shiny and glistening, all dirt gone. For that reason alone, I love Idaho.

Heavy Duty Benches

I saw many wonders at Yosemite National Park, but I was most impressed by their reinforced benches. The middle support is vital.

The Case for Compass Watches

With trusty compass watch on wrist, I felt well-equipped to navigate foreign lands. Was my confidence well-placed?

Yeah baby. I'm very pleased with how useful it was, but not in the way you'd expect. I rarely found myself hiking in wilderness areas in need of direction. Most of the time, the trails were well-marked, or I could use the sun or local landmarks to roughly orientate myself. But in the cities and even inside buildings, it was valuable being able to quickly find north. I especially recommend having a compass in Las Vegas. In the middle of those vast gaming floors, with no view of the outside world, it's hideous trying to figure out where you are. A quick look at the compass and you're lost no more. Surely the casinos wouldn't deliberately make it hard for you to leave, but there was a definite lack of signage and mappage, and with no windows to the outside world, it would be easy to give up and stay, rather than find an exit. 

The watch also came in handy because the cheap sat nav bought from Walmart was not trustworthy, especially first thing each morning. For the first few minutes after she was turned on, she'd give random directions. The worst occasion was in the city of Bend, Oregon. We left the hotel and wanted to hop on the highway north to Portland but ten to fifteen minutes later we had circled around the suburb and were back at the hotel ! If only we'd trusted the compass and just headed north. After that, I knew to always check that the sat nav directions were vaguely right.

Now that I'm back in familiar territory, I'll rarely use the compass, but it's nice to know it's there if I ever need to switch to Bear Grylls mode.

Driving on the Right

Of course I was trepidatious before driving on the wrong side of the road for the first time. I was secretly thinking that Thrifty were mad to let me hire a car for 40 days. But when I got behind the wheel of my Toyota Corolla at the start of my epic road-trip across the US and Canada, the difficulty was not what I expected.

Keeping to the right turned out to be the easiest change. I'd prepared a few "Keep Right" sticky notes for the inside of the car to remind me, but they weren't needed. My bigger problem was that being in a left hand drive car, I had to re-learn where to position the car in the lane. If I didn't concentrate, I'd drift over to the right of the lane as if I was on the right side of the car. Being in dense traffic in downtown Vancouver, it took all my focus to keep in the narrow lane, especially as we wound around curves and up hills.

The next problem was roundabouts. Luckily for me, they are very rare in North America, but it only takes one to destroy a car. Without thinking, the first couple I found, I was concentrating so hard on keeping right and travelling anticlockwise around the circle that I completely forget to look left for any traffic. It was only luck that nobody was around.

I was also caught out a few times when I had to reverse around corners, or into main roads. I'm a naturally fast reverser, and without consciously thinking, several times I scarily found myself reversed onto the wrong side of the road, facing oncoming traffic. After those episodes I knew to be cautious about reversing, and deliberately slowed myself down, to give myself time to envisage where I should go.

And finally, having the indicator stalk, gear stick and handbrake on my right instead of the left took some more brainpower to adapt to. For the first twenty times I tried to indicate, my wipers were turned on. But nobody died.
