If she is a boy and he is a girl, what do you think are my grades in English class?
But they are comedians , so it may be in their favor.fresh_42 said:I assume they thought this would save marketing costs. Unfortunately for them, they made the calculation without people's subconsciousness. Typical case of: not thought to the end.
I once lived in an apartment building with neighbors named Buse (her name, Busen= bosom) and Bock (his name, = buck).
How about one-finger push-ups? Any time soon? ( Don't try it , may fracture the finger)Psinter said:I started doing push-ups regularly and after a while, one day, I felt like a small sense of confidence that I could do one arm push-ups. It was as if without trying, I could clearly gauge my own capacity at that point. Got myself on the ground and to my surprise, I could do them!
It felt really good. I was like: "Oof. I'm strong."
But once I was able to do it, I realized that it didn't require that much strength to do one arm push-ups. It wasn't something that required hard training to achieve. Although I'm not sure if the weight of the person influences the amount of training needed by that person. I have always been light. Whenever I'm moving something heavy, I always get told that the object can lift me, rather than the other way around.
So the random thought that crossed my mind is that when one exercises regularly, one sort of gets a feeling of one's own capacity to perform a certain task. Whether you can do it easily or whether it will cost you. I don't know how to explain it. You just can assess the situation and your capacities better than when you don't exercise at all.
Not at all. I can push-up my finger without any noteworthy efforts as often as I like.WWGD said:How about one-finger push-ups? Any time soon? ( Don't try it , may fracture the finger)
Well, at least a sign of honestyWWGD said:Woman in coffee shop giving the finger more openly today, no pretense of scratching her face. Kind of funny but sad to see deranged people outside of special housing.

Why don't you date her?WWGD said:Woman in coffee shop giving the finger more openly today, no pretense of scratching her face. Kind of funny but sad to see deranged people outside of special housing.
You mean like their eyebrows? :).Psinter said:Why don't you date her?
Crazy ones make for good dates.

Just kidding. Don't go there.
But following that line of thoughts, I think I once heard someone say to not think that you can change someone. Looks like some people who date, think they can change parts of their partners that they don't like. That they can convince them to be different.
But, you have a point dating wise. I have a magnetic personality:every deranged person around seems to find me and approach me.Psinter said:Why don't you date her?

But following that line of thoughts, I think I once heard someone say to not think that you can change someone. Looks like some people who date, think they can change parts of their partners that they don't like. That they can convince them to be different. And it somehow doesn't go as expected.
I know this characteristic too well. Always thought it's only me ...WWGD said:But, you have a point dating wise. I have a magnetic personality:every deranged person around seems to find me and approach me.
And now for the next lesson: it's also a (2,0) or a (0,2) tensor.WWGD said:I finally understood why a matrix is a (1,1) -tensor. After like a year.
Back in undergrad days I was chatting to a friend in the corridor when a girl we both knew came round the corner, took one look at my friend, said "oh!" and went haring off back round the corner. I gave him a "that was weird" kind of look and he shrugs and says "It's my animal magnetism - I just need to figure out how to flip the polarity..."WWGD said:But, you have a point dating wise.

...and only if it's got the right transformation laws.fresh_42 said:And now for the next lesson: it's also a (2,0) or a (0,2) tensor.![]()
I found the answer through meditation : Hom, Hom,...Ibix said:...and only if it's got the right transformation laws.
Only for physicists. For me it's only important how many asterisks are involved! That's sufficient for me to know what to do. And don't bring up co- and contravariances. My book about homological algebra uses them differently anyway.Ibix said:...and only if it's got the right transformation laws.
OK, but still you have a condition over and above being a square matrix. The Christoffel connection coefficients are representible by an NxNxN matrix, but aren't a tensor.fresh_42 said:Only for physicists. For me it's only important how many asterisks are involved! That's sufficient for me to know what to do. And don't bring up co- and contravariances. My book about homological algebra uses them differently anyway.
But isn't a matrix just a 2D array? Or maybe it is the confusion of notational/definitional differencees?Ibix said:OK, but still you have a condition over and above being a square matrix. The Christoffel connection coefficients are representible by an NxNxN matrix, but aren't a tensor.
What type of or theory of Homology are you using?fresh_42 said:Every "rectangle" collection of numbers in any dimension can be interpreted as a tensor, a cube is just #\sum x \otimes y \otimes z##.
Covariance and contravariance determines, whether a functor keeps the direction of mapping arrows or converts them. I have never seen a second category by the way physicists use these terms - there are always only vector spaces present. If at all, it's the transition ##V \rightarrow V^*##, but they attach it to either ##V## or ##V^*##, so again no second category.WWGD said:What type of or theory of Homology are you using?
This looks more like geometric algebra. Or Simplicial.fresh_42 said:It's the old discussion what a transformation and what its matrix is. A tensor to me is simply an element of a tensor algebra, resp. space, if only tensors of equal rank are involved. As soon as I have a basis of the constituent vector spaces, I have a cube or whatever a matrix (not necessarily square) in higher dimensions shall be called. Their use by physicists makes me dizzy. It always sounds curved somehow, but it's flat as a board.
No, it looks like homological algebra, the category thingies, at least the books are titled so, both, the English and the German ones.WWGD said:This looks more like geometric algebra. Or Simplicial.
So it depends on what "is" is?Ibix said:Can be interpreted as, sure. But can be interpreted otherwise too (e.g. the connection). So I object to the "is" part of "a matrix is a tensor".
Insight?fresh_42 said:Can someone please find a word for "Erkenntnis". The only possibility I see is "knowledge", but there is a fundamental difference between knowing something and understood something! Too bad we don't have philosophy here. I would be very interested which consequences it has to a society, that only knows things and doesn't care about "Erkenntnis".
And, no, re-cognition doesn't count. It's only to realize what's already known. I'm looking for the knowledge behind "Eureka!".
Oh, I haven't thought about this one. Probably because it means something different in German. Insight here reflects on a revised and corrected position, or the possibility to view formerly closed documents.Jonathan Scott said:Insight?
They're more or less a product of chromatic aberration, yes. I'm not sure you can really call it chromatic aberration when it's not part of an optical system designed to form an achromatic image, but it's the same root cause, certainly.OmCheeto said:Are rainbows chromatic aberrations, or vice versa?
I play boulesfresh_42 said:I've incidentally found a place in town today where people can actually play boules - people who played it inclusively.
Correction: Pétanque.Ibix said:I play boules

Against fools
While eating moules.

Your turn.
You know this doesn't work with the actual pronunciation?Ibix said:I'll be frank
I play petanque
But I don't clank
'less I bring my tank.
It works with the usual anglicised pronunciation. And just Googling it (from an English computer in England, anyway) gives me the same pronunciation. How's it supposed to be pronounced?fresh_42 said:You know this doesn't work with the actual pronunciation?
Our town is considered the most multi-cultural in Germany, but I didn't know that French belong to this mixture.

Are we talking about the Haggis people?Ibix said:Not my fault if foreigners can't pronounce their own language right.
