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.

Goody, first reply is mine
 
We have a winner! Nice JorisL. :approve:
 
What a relief! When I saw the "Thread Closed" announcement, I thought that Om and Zoob and I had killed another one. :blushing:

edit: Not that I'm necessarily going to, but in this new PF4 format, can I still pull a quote from the old previous thread to use in this one?
 
I have some friends who used to be my project mates, they are looking for new jobs too. Should I introduce them to my company ? Helping people is not to get thanks in return, I'm only afraid they may "kill" me some day.
They tell me they are working with Russians and those Russians are strict bad arses.
Someone can offer me some insights.

God only knows Danger, and I don't believe in a god. You can try.

Danger, so you have a small crush for Swedish TV? :) I haven't. :D Actually, I have not seen that SF series at all, not a single episode, so I don't know anything about it, well, except that I think it is about humanoid robots or something.

Now to something else:
I now know what has got to be the most destructive thing you can do in mathematics... anyone know what I mean? Anyone? Anyone? Take a guess...

Depends on how much trouble you are willing to take.

Mark V Shaney did it 30 years ago.
And then they made a young Ukranian who beat the Turings test (arguably).

Hmm... @AnOldStudent

I will, just for the sake of experimentation, but not right now. These damned "Alert" things keep popping up so fast that I don't have time to say hello to myself. That's okay unto itself, but for some reason my 'book is running very sluggishly right now. (I think that maybe the new data packets from "SETI @ Home" are trying to sneak out of their quarantine area and use PF processor time. :oldgrumpy:)

This is the only example of it that I've ever seen. I like it very much, except for the aforementioned issue of me not understanding Swedish. That's my fault, not theirs.

Leave your calculator in your pants pocket at the laundromat?

For me, during my college years, it would be: take a math class at 8:00.

How come I can't see your avatar?

That can surely be destructive :).
But no, I was thinking about something that is terribly destructive to mathematics itself: Killing vector fields.

I have no idea. Works just fine over here.

Clear your cache, basiL. Might help.

True story... he's Bender and Dr. Zoidberg grinning at the "camera". I've never had a glitch with seeing it.

:nb) Never done that before, it's sure a good sport on the beach.

My final rant about Killing vector fields:

Actually, I can't understand how mathematicians and general relativists can be so careless that they employ them. What on Earth are they thinking? It's not just the name. Think about it:

Vectors are pointy rascals. Pointy = dangerous.
Vectors are unimaginably thin, which means they must be sharp as razorblades.
And they can point in ANY direction!
And they can be arbitrarily long!
And, now, imagine an ENTIRE field of them! A Killing Field!
They could be the end of the field of mathematics as we know it!
Euler would have cried a river of tears.

Perhaps it's Euler's fate.
Pointy is not always dangerous.
Here we consider the Tensor field
Whose values are measured by Lie derivative.
If I'm dying,
Will you come save me ?

I will do my best, but try to keep a distance to those vector fields. If you stop functioning, I may not be able to neither derive nor integrate you.

Ok, I'll stop functioning. :approve: Don't ever call me a static object then. :D

Just saw it today too, Dan.

Not feeling like doing my reading. *sigh*

You're probably still far too young to realize it yet, but there is absolutely nothing like a good nap to get you back into the swing of things.
