    News Could changes in Dietary Patterns of world population alleviate hunger problems.

    I quite agree with what you said, all or more than one of the above approaches should be applied. Point number 5 seems to me to be a very good one. I can understand that people can't be persuaded to reduce meat consumption, for such a thing impinges upon freedom of choice. But wastage of food...

    Why does my cat meow a lot after she catches a prey?

    You mean, she wants water? Don't you think the other explanation is more fascinating than this ,i.e that she wants us to share food with her?

    Yes , then that is good. But I heard reports similar to the following that suggested that cattle feed is foodgrains :- http://monthlyreview.org/2009/07/01/origins-of-the-food-crisis-in-india-and-developing-countries Such practices seem wasteful. But , in case cattle can be supported on...

    But the cattle will still consume lots of fodder for it's entire lifespan , say 3-4 years on an average. And that fodder will need land. And in the end the cow will be eaten in a week or so. The farther our diet is from the solar energy in the food-chain , the more resources consumed.(A...

    Wouldn't you rather have tofu ? :biggrin: No just kidding. Yes, you are right . I did mention it in my first post that changing food habits is not practical. But what I meant was smart changes in dietary patterns. Not complete abstinence . That is way too extreme. But if a person on...

    Why does my cat meow a lot after she catches a prey?

    Or is it because she wants to share food with us ? Give-and-take, maybe ? We give her cat-food ,so on occasion , when she brings home food, she maybe wanting us to have a bite or two. How do cats view their owners is a question that props up in my mind. Cats in the wild are solitary animals. So...

    Most of the world consumes non vegetarian food significantly. http://en.wikipedia.org/wiki/Virtual_water#Agricultural_products" compares the virtual water requirements of various food products :- I am showing the water requirements just as an example. But even land required to produce 1 kg...

Whenever she catches a prey be it a rat or a pigeon , she has a tendency to meow a lot in front of us. She...

    Can someone explain what Bertrand Russell is saying on Aristotle's logic?

    "Any thing that is a Greek, is a man in virtue of being a Greek." I think I will have to read some literature before I can understand whether this statement has existential quantifier or not. I am simply unable to decide and hence I am confused about it. The if-then statement I am somewhat...

    Can someone explain what Bertrand Russell is saying on Aristotle's logic?

    "Any thing that is a Greek, is a man in virtue of being a Greek." Now I am confused , doesn't this imply something about existence of Greeks. However , "For any x, if x is a Greek, then x is a man." , this one seems better. But this is just writing the if-then statement in a more formal way...

    Can someone explain what Bertrand Russell is saying on Aristotle's logic?

    This seems a good point to me.Could you provide some good references to the above. I would really like to learn more on this point of view. I am not sure if we can use "anything" as "it" . The statement "Anything is Greek" can't be taken in isolation. It seems meaningless.(although, "It is a...

    http://books.google.com/books?id=Ey94E3sOMA0C&lpg=PP1&pg=PA190#v=onepage&q&f=false" Aristotle's Logic I want to know whether I have understood this right. We shouldn't be saying , "All Greeks are men,all greeks are white,therefore some men are white". So we should be saying "there are...

    Proving Bijectivity of N=1/2((a+b)^2 + 3a + b)

    yes N(a,b) takes a pair of natural numbers (a,b) to a single natural number N. But why should the other way around be a problem. Since the map is injective (as the problem asks us to prove) , there would also be an inverse map N-1 such that N-1(N) = (a,b). of course proving it that way would be...

    Proving Bijectivity of N=1/2((a+b)^2 + 3a + b)

    Homework Statement Prove that the function N = 1/2*((a + b)2 + 3a + b) is an bijective map from the set of natural numbers to the set of pairs of natural numbers (a,b). Homework Equations N = 1/2*((a + b)2 + 3a + b)The Attempt at a Solution I tried to prove the other way around that this...
