If a man (negative) and a woman (positive) are usually attracted, but sometimes 2 men or 2 women are mutually attracted instead.. could the same thing happen with electrons/protons? Could the rare electron, for example, be attracted to one of "it's kind"?

Ok, so bird flu or SARS or whatever wipes out the human population (like gone) leaving practically the entire rest of the ecosystem intact. Bears and primates battle for dominion over dry land. Who wins?

Ok, here are the rules:
1) No peaceful resolution; coexistence and/or isolationism be damned! The bears and the primates want it all and they want it now.

2) No write-in candidates. The dolphins are not taking to the streets. The armadillos do not take charge in the 11th hour for the upset.

3) No other animals as key victors, however they may enter into combat (strategically or otherwise). The monkeys can form an alliance with the lemurs, but only insomuch as the US formed an alliance with Romania to help fight the war in Iraq.

4) We left all of our toys behind. Cars, grocery stores, indoor plumbing, strip clubs. And a lot of human carcasses.

All right, so who's your money on?

I know there's places where you can swim with and interact with dolphins. Is there anywhere like that but for playing with pandas? I love pandas and always see videos online of people in China playing with them; or is that only open to researchers?

a ordinary golf ball ,dropped exactly at the same time from a height of say 50ft ,will both reach the ground together,even though one is far heavier and bigger than the other~ok

my Q is- if 2 bouyant objects one far larger than the other
were taken down say 100ft under the sea or lake etc,and released both exactly at the same time,would they both travel
at the same speed upwards together or would weight and size of each object,have an effect on their individual ascending speed

I once heard that if every day you predict that the weather tomorrow will be pretty much the same as it is today, you will be statistically more accurate than a proper weather forecaster. Is this true? I know it sounds stupid at first, but when you think about it it is feasible, since the weather on two consecutive days will more often be the same than not.

Assume that a violin string of length 10 is held so that at time zero its shape is given by the function:


f(x) = (x/4) at (0< x < 4), (-x/6 +10/6) at (4< x <10)

and released, so that its initial velocity is zero. Find the function u(x,t) that describes the height of the point x of the string at time t. Use 5 terms of your series to determine the position of the midpoint of the string at time t =5.

We only barely covered partial differentials in class so any help would be useful.

And how come I can be conscious of having varying energy levels?

In February, you have a balance of $270 in your bank account. Each month you deposit $45. Let January = 1, February = 2, and so on. Write an equation for this situation. Use the equation to find the balance in June.


y – 270 = 45(x – 2) ; $450
y = 45(x – 4); $270
y = 45(x – 4); $180
y – 270 = 45x; $45
