editDepth of water
editHi there:
I would like to know the depth of Douglas Channel in British Columbia Canada? An average is fine or the deepest in fathoms or feet.

- (Whoever finds an answer might improve our stubby Douglas Channel article with the information, if he or she has time.) Comet Tuttle (talk) 06:07, 6 June 2010 (UTC)
- This gives a channel depth of 100-300 fathoms (190-570 m or 600-1800 ft). Ghmyrtle (talk) 06:35, 6 June 2010 (UTC)
Electromagnetic wave
editI wont to ask about the sfe level electromagnetic wave Foralaa (talk) 09:39, 6 June 2010 (UTC)
- If you mean the safe power level of electromagnetic radiation, there is no absolutely safe level of anything. For instane, you can be electrocuted with a 1.5v battery if you apply it in the right (wrong) place.--PeekyWeedia (talk) 10:50, 6 June 2010 (UTC)
- A 1.5v battery would likely need to be applied directly to the heart. Therefore it would be practically impossible to be elctrocuted by such a low voltage source in normal cicumstances. See Electrocution. Also see this website [1] As for the original RF question, see Mobile phone radiation and health. PeekyWeedia, you need to provide a reference or link to a relevant article when you answer questions here.--220.101.28.25 (talk) Contribs 16:38, 6 June 2010 (UTC)
- How much current can you get from a 1.5 v cell? It only takes a few 100s of mA to cause ventricular fibrillation. Ref: PD6519:Part1:1988 (IEC standard) —Preceding unsigned comment added by 79.76.157.65 (talk) 18:11, 6 June 2010 (UTC)
- Not even "a few 100s", see The Physical Effects of Electricity somewhat ironically found via the article on Thomas Alva Edison. (reference № 35) --220.101 (talk) Contribs 05:20, 7 June 2010 (UTC)
- There is contradictory evidence regarding the safety of particular types / frequency of electromagnetic wave. See also Electromagnetic radiation and health and Wireless electronic devices and health --220.101.28.25 (talk) Contribs16:48, 6 June 2010 (UTC)

- Peeky seems to be ignoring Ohm's Law and skin resistance. As for the "Darwin Award" story, I doubt someone wanting to measure his body resistance would stick Simpson probes through the skin of his thumbs into the meat. Nerve endings and all. The Simpson in that dubious report had a 9 volt battery, not just 1.5 volts. Of course it is impossible to state how much current the world's most vulnerable heart might require to cause problems. The dubious anecdote (note no name or date is associated with it, just a gruesome "teaching story") claims the guy's "internal resistance" was 100 ohms, without stating how that was measured. Ohm's Law says that a 1.5 volt battery would have produced 15 milliamperes, provided there was no other resistance in the leads or the meter, compared to 90 milliamperes from a "resistanceless" Simpson meter. My respect for the folks at "Darwin Rewards" is greatly lessened by them repeating this story. Edison (talk) 00:25, 7 June 2010 (UTC)
- Well put, but how could an editor with a name like Edison be wrong? 220.101 (talk) Contribs 04:49, 7 June 2010 (UTC)

Land Rover but not a Land Rover
editI've seen a car near me that is a Land Rover in design, but badged with a Spanish-sounding company name, not as a Land Rover. When I say it's like a Land Rover, I mean just like one, not like a knock-off. Looks like the County Series. Did Land Rover sell the old design and dies etc on to another company, and if so, can anyone tell me what they are called? DuncanHill (talk) 11:25, 6 June 2010 (UTC)
- Land Rover is now owned by Tata Motors, which I guess is Spanish sounding (though Indian). Maybe Land Rovers are now re-badged.--Shantavira|feed me 11:50, 6 June 2010 (UTC)
- No, Land Rovers are still badged as Land Rovers (and anyway, I am familiar with Tata and wouldn't mistake their name and logo with anything else. DuncanHill (talk) 11:56, 6 June 2010 (UTC)
- Found it - Santana Motor. DuncanHill (talk) 12:04, 6 June 2010 (UTC)
Dutch
editWhen one has a few drink before doing something important, this is called Dutch courage and is used to build confidence. When one takees a girl out and makes her pay for her self, this is called going Dutch. why is this? What do these things have to do with the Dutch. Thanks —Preceding unsigned comment added by 82.3.145.145 (talk) 20:11, 6 June 2010 (UTC)
- The origin I accept is described at Dutch uncle#origins 77.86.124.76 (talk) 20:42, 6 June 2010 (UTC)
- I've also heard "Irish courage" applied to whiskey. Dismas|(talk) 20:53, 6 June 2010 (UTC)
- These idioms are probably the remnants of old negative stereotypes regarding the Dutch (in the examples you provide, probably that they are drunken and miserly). These probably still exist, though admittedly less obviously today. I can't think of a good contemporary example at the moment. Intelligentsium 23:17, 6 June 2010 (UTC)
- I've always thought that they showed the Dutch in rather a good light - fond of a drink and believe in paying your own way. DuncanHill (talk) 23:23, 6 June 2010 (UTC)

- Ya, you could spin it that way too :-)
- DaHorsesMouth (talk) 01:48, 7 June 2010 (UTC)
- Oooh, you're in Dutch now. Clarityfiend (talk) 02:12, 7 June 2010 (UTC)
- "Going Dutch" is another way of saying "Dutch treat", which is intended ironically, because if everyone pays their own way, no one is "treating" anyone. Aye, there's the Dutch rub. :) ←Baseball Bugs What's up, Doc? carrots→ 03:16, 7 June 2010 (UTC)
- I had heard that Dutch courage comes from when London was quarantined with the plague and the Dutch used to come and deliver food for the people of the city, they had to be drunk to go anywhere near the place. Whatever happened to that rumour, it seems to have disappeared? 80.47.139.98 (talk) 15:44, 7 June 2010 (UTC)
- AS usual, we have articles on Dutch courage and Going Dutch (with a redirect from Dutch treat). ---— Gadget850 (Ed) talk 19:39, 7 June 2010 (UTC)
