AI Thread Summary
The discussion revolves around a variety of topics, beginning with the reopening of a thread on the Physics Forums. Participants express relief at the continuation of the conversation and share light-hearted banter about past threads. There are inquiries about quoting from previous threads and discussions about job opportunities for friends. The conversation shifts to humorous takes on mathematics, particularly the concept of "Killing vector fields," which one participant humorously critiques as dangerous. Participants also share personal anecdotes, including experiences with power outages and thoughts on teaching at university. The tone remains casual and playful, with discussions about the challenges of winter, the joys of friendship, and even a few jokes about life experiences. The thread captures a blend of humor, personal stories, and light philosophical musings, all while maintaining a sense of community among the forum members.

Kind of weird to have an issue with Turkey _exactly_ on Thanksgiving day, reading about " Turkey shooting down a Russian airplane". What, is this "shooting down" a new figure of speech? Yet another attempt by a journalist to make a Thanksgiving joke? What the $#% does it mean? Am I the only one who had to decide whether it was the country or the bird when I first read it? One of the two should change the name to avoid future confusion.

Yah, I thought the turkey was protesting the annual genocidal event.

With the genocidal event being the " shooting down of a Russian airplane". What I can I say, it's the new slang.

I think most of the world is racist; "Racism of various forms is found in every country on Earth".

I used to be very racist. (When I was about 10)
Then I wasn't very racist at all. (When I was about 18)
Now, it's only mean people that I don't like.
And they come in every variety.

If everyone, in every nation, cooperated, with everyone, in every other nation, we could conquer, the madness.

there should be a science videogame. For instance in the style of Half life or metroid (with the scan visor). I mean a serious scientific videogame where after playing you are good enough to work at the Large Hadron Collider. I am serious about this.

I also demand royalties from this game if it is ever made, after all I did make the idea.

I have some sort of ammeter I picked up at the swap meet once that measures 0 to 8 amps. By this meter, the extreme superiority of the Duracell battery is evident. A brand new Energizer D cell puts the needle up to a little over 4 amps. The new Duracell D cell, however, maxes out the meter.

The mornings are especially hard to adjust to. I helped myself cope this year by buying a cuddly and warm pullover. When I wear it, I feel like a big, warm, blue, fuzzy bear.

hmmm...
That's a novel way of checking out the internal resistance of a cell.
Please don't try that with a lead-acid version.

ps. PM me your home address, and I'll mail you a couple of resistors, to, um, do that less dangerously.

At lunch specials in many Chinese restaurants, one has the option of switching from white rice to brown rice for an extra $1.00. I always
suspected it is a complete ripoff. My trip to Chipotle's for lunch verified this: Chipotle's offers the choice of brown or white rice with
no price difference. If the actual difference of cooking brown was close to $1.00 more than cooking white , they could not afford to charge the
same for both, given the average meal is around $9.00.

Not really. Issues of internal resistance aside, the amperage a battery can deliver is related to the surface area of the "plates." Larger batteries deliver more amperage simply because the plates are more or less in proportion to the physical size of the battery. The Duracell battery delivers more than double the amps of it's energizer cousin of the same size, however, because the Duracell more than doubles the surface area of the zinc electrode. In an alkaline battery, the zinc electrode is a little bag of powdered zinc and electrolytic alkaline paste at the center of all the manganese dioxide. The Duracell simply uses more zinc powder.

The project I'm working on is electromagnets. So, what's of interest here is that the same electromagnet will be more than twice as powerful with the Duracell battery than it is with the Energizer. Same voltage, but more amps.
Please don't try that with a lead-acid version.
Why would I try to measure a 200+ amp battery with a meter that tops out at 8 amps?

ps. PM me your home address, and I'll mail you a couple of resistors, to, um, do that less dangerously.
I have plenty of resistors. Regardless, it would be of interest to throw one in the mix and get a more accurate picture of the ratio of the difference.

I was at the swap meet today and noticed an interesting bow. I am a fan of archery, and wanted to examine it, but there was a guy who had his eye on the same bow, who had gotten there before me. He picked it up, drew the string back to test the strength of it, and the lower limb of the bow snapped off with a sickening crackle. I was suddenly very happy he got to it before me.

I could be wrong, but I have the impression that the Chinese don't naturally eat brown rice, therefore they'd consider it an imposition to have to buy and cook a separate batch of it for crazy foreigners who want it.

Could be true, but AFAIK, what we call Chinese food in most of the U.S is already significantly different from the food most people eat in China( I wonder if a burger place in China qualifies as a " U.S restaurant"). And I believe the same goes for Mexican, Thai, etc. as prepared in the U.S: all the edge is removed to adapt to the U.S taste. Most people want to think they are eating/doing something exotic without actually wanting to take a leap into the unknown.

I always wondered why so few people get killed/hurt when learning archery. While teacher shows, students are carelessly turning around while they hold their respective bows. Seems like a recipe for disaster, specially with easily distracted children and teens.

I don't know about NYC, but here in San Diego most Mexican restaurants are owned and operated by Mexicans for a Mexican clientelle. Chain Mexican restaurants like Taco Bell and Del Taco are obviously not authentic, but I get the impression all the others (there's one about every block here) are more or less what you'd find over the border. They're not what you'd get eating in a Mexican home, they're more like the Mexican version of the American "greasy spoon" restaurant. The menu is limited to things that are fast to prepare, cheap, and filling. It's working-class Mexican food, just like the greasy spoons were working class American food, before McDonalds put them all out of business.

Yeah, you see that in movies about summer camps. If those movies are authentic, I would expect the kids are shooting each other all the time. I think serious archery lessons are one-on-one situations: one teacher coaching one student at a time. Although, back in the day when the bow and arrow were serious weapons of war, they must have had group training.

You're right, there are a few authentic Mexican ones here too, but I doubt there are many places where you eat like one eats in China,etc. even in greasy-spoon equivalents. But maybe I am wrong.

And I actually had a pretty nice experience in one of those authentic Mexican places: I was the only non-Mexican one, yet I did not feel like an outsider. It was a strange but nice experience. And the food was pretty good too.

I think a lot of the errors I make ultimately go back to something that is, in hindsight, rather elementary. So either we are both idiots or this might happen to anyone. I prefer to think the latter.

A few years back this girl told me her mother had told her that oil was old dinosaurs. I'd never heard that before, and thought it was pretty hilarious. However, it then struck me that some small percentage of oil might well be old dinosaurs, and I am now wondering what percentage that might be. "Old dinosaurs" in the sense of life that was not plant life.

I'm pretty sure that coal is derived entirely from plant life, but not so sure about oil.
I have wondered for a while how it is that in some places there are coal deposits, but elsewhere there is oil instead.

Yeah, that would just be part of the plant life content of oil (minus bacteria). I'm looking for the non-plant life content.
