In theory it’s straightforward - your meridian line would be ANY true north line. For their method to work, the map needs to indicate the longitude degrees, minutes and/or seconds across the bottom in increments. Then you basically line up the two numbers that match (ie draw a line from 86W on the top of the page to 86W on the bottom). Then that line becomes your meridian, and you create new “magnetic north” lines from there by adjusting for declination.
EVs make a difference for anyone in an area with low density. I live in the country relatively close to population centres, but it’s impossible for me to ever imagine transit being even near me.
We will literally always have a need for small, individual vehicles of some kind for most the population. If we could reduce that to one car, then supplement with transit, where available, or carpooling? Then also make that car an EV instead of ICE? That’s a huge emissions reduction
I can speak to this as I’m just going through it now.
I’m a young male in good health. I started having weird heart palpitations randomly starting last year. Had them four times, but they normally go away after 20ish mins. GP reviewed me, said it seemed fine, but to go in to ER if anything about them changed (ie more frequent, more intense, lasted longer).
Last friday they went on for an hour, so I went in. Entered at 11am.
Was triaged within 15mins, including an ECG. Once they confirmed it wasn’t an active heart attack, I sat in the waiting room for two hours. I then saw a doctor, got a chest X-Ray, and bloodwork taken within 45mins. I proceeded to sit in the room hooked up to the vitals monitor for four hours while they ran my bloodwork, and the ER doc came back. He sent me a requisition for a cardiologist and told me to take aspirin until I saw the specialist.
I saw the Cardiologist on Wednesday, and he’s explained he’s not concerned given my lack of other risk factors. He’s now sent me over for an ultrasound and 36hr halter monitor next Monday. He said unless something weird comes back or he wants another test, he won’t see me again, and I should follow up with my GP 2 weeks after I finish the halter monitor.
So within 3 or 4 weeks I had a full range of tests done, and my biggest expense was $7.50 parking for the 30min cardiologist appointment, which I was actually unironically complaining about to my wife last night.
I’ve got the 2021 Kona EV and while you do lose range in the winter, it’s more like 100km/450km. That’s with intense grip heavy winter tires and the heater running. In Ontario, so regularly ran it with -35c temps. It’s cold and you lose some range, but not 400miles out of a 700mile range
Depends on how accurate the map is. If possible, align minutes and seconds. Basically what you’re doing is drawing on your own longitude line.
For anyone else who stumbles across this, All longitude lines are true north lines, meaning they point to the “true” North Pole, or the top of the globe, and converge there. However magnetic north moves year by year- due to the molten core of the earth shifting and other factors. Maps will typically come with a year they’re printed, and sometimes with the declination you need to adjust by (is, 0.3deg/yr since it was printed), otherwise you need to look it up.
If you’re enjoying learning and want to put your skills to the test, check out orienteering races, or adventure races. They run across most of the world, and the shorter ones are a great way to test out your skills. I’m a huge fan of them.
