    Random Thoughts
Click For 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.

For a while there, I thought you said you had made 1000 crunches until others replied to you. Silly me. :rolleyes:

In middle school:

Friends: You are in love? We are so happy for you. Wait until we tell the whole school, the whole internet, the FBI, the Russian military, and whoever else we find on our way. Even thought you explicitly told us it was a secret.

And in a week or so even the European Union knows you are in love. :confused: :rolleyes:

The closest that I've been to that is once when I was watching a strong man contest on TV. I got motivated to do 300 pushups (sets of 25). It didn't take years. :oldtongue:

Weird new trend for TV programming around here : TV shows starting at unusual times and with unusual duration. Example: George Lopez' show sometimes starts at 2:13 a.m and ends at 2:51 a.m. Other shows will start at, e.g., 1:07 a.m until 1:45 a.m. Must be just more commercials I guess.

Sure. But be aware of Evo.

There's been some of that going on here, too. I don't like it. You can miss the start of the next thing you want to watch.

BTW Thanks for reminding me that I need to add Jim's quote to my special/meaningful list.

Wonder what would happen if a poorly-trained robot read the sign in the Runner's store: " never stop running".
Seems like a good Turing test to tell appart people from machines.

Yeah, no. There are people with various neurological and psychiatric disorders who would take that sign literally.

I guess that is why the have the joke: my mom has been running 2 miles every day. We have no idea where she is.

Wonder when the day will come where strings , shoelaces and any loose objects coming out of clothing will disappear. It seems like loose clothing and other loose objects (e.g., chains, watches, shoelaces) getting caught in machinery is one of the main reasons for accidents. I myself will soon change towards Velcro and will aim to buy clothes without "appendages".

I feel kind of petty; MLK had a dream of the brotherhood of humanity and people being judged by the
content of their character. Me, I just want to be able to watch any show on TV whenever I want . That is my big dream.

Actually inexperienced and too careless, causes for the accidents.

Of course, but you cannot keep track of everything that happens around you all the time, so it seems like a good idea to remove
causes of problems that you can remove.

Today I tried to remove the rear axle nut from my car. It was really torqued on there, I couldn't break it with a 1/2 drive breaker bar 2 feet long. So I supplemented that with an eight foot cheater bar. All I accomplished was to sheer off the 1/2 lug where the breaker enters the socket.

A look at an auto forum taught me that people have broken even 3/4 breaker bars trying to loosen this nut. You need an impact wrench or a dedicated tool. It's supposed to be torqued to 250 ft lbs, but some shops go overboard and people have found their axle nut torqued up to 400 ft lbs.

If you are anywhere as big as your avatar it should be a breeze to "Detorque" the rear axle.

impact wrench and air compressor is a good investment.
I just replaced all twenty of my wheel lug nuts because some bonehead laid on his tire shop mega-impact wrench hard enough to deform the threads.
Thank goodness the nuts yielded before the lugs...
I started asking at the tire shops how they torque lugnuts. I trade now at a place where he lubricates and torques them to 80 ft lbs, which is plenty.
Lubrication assures i'll be able to loosen them with my lug wrench on a dark snowy night alongside a boondocks road.

The trouble is I don't have tools as big as my avatar.

80 ft lbs sounds about right for where I found my lug nuts the first time I undid them. I had to stand on the lug wrench and bounce. This axle nut is on the big side, 36mm, torqued to hell and back, and every do-it-yourselfer who tackles it has problems breaking their tools on it. There's one dedicated gizmo that's less than $15 which everyone whose tried it has said worked. I'll try that first.

I tend to think most of those guys go overboard with their impact wrenches. Possibly, possibly to force you to take your car back there to be serviced when you find you can't undo any of your fasteners. That's bogus that they deformed your nuts. I mean the threads on your nuts. Your wheel nuts. I mean.
