Why can't all animals be born one way? I always wondered why some animals give birth to a live baby while others lay eggs then they hatch?

20 inches of lead in more effective than 20 inches of water, but the combination of 10 inches of each is more effective than either.

Why?

Are there any actual strategical card games that involve adding/subtracting etc? Most games have you match or go up and down, in my opinion there's no strategy to those games and you don't 'build brain cells with them'. I'm also trying to help a relative practice math. It can be anything you can think of from very easy to very hard. Please state the name of the game and if you can take a minute to find a website, that would be great! :)
Thanks

I understand that the state of a system at any instant of time is completely specified if we give the positions and velocities of all the particles, but why not also the accelerations and higher derivatives?

Anything that burns, because it is carbonic thats why it is burnable or even if it is not carbonic, the oxyzen in atmosphere is enough to help burn anything.

Will there come a time when everything has been eaten up except other Black Holes, and these will eat each other up until there is only one Black Hole, and maybe it will explode into a Big Bang on account of having eaten too much, and everything will start all over again???

Let (X, M u) be a measure space, where X is a set, M is a sigma-algebra on X and u is a measure defined on M. Let f_n be a sequence of functions defined on X and with values on [0, oo] such that lim f_n = f. Suppose that lim Integral f_n du = Integral f du < oo (the integrals taken over X).

Show that, for every set E of M, Integral_E f_n du = Integral_E f du, where Integral_E means integral over E. Also, show that this conclusion may fail if we have lim Integral f_n du = Integral f du = oo

Thank you.

january...april...july...october...?

wouldnt you prefer a secular logical calender that splits the year neatly into halves and quarters?

because this has an astronomical basis, it is applicable globally...and might be taken up planet wide [as new year is these days]

In the twin paradox the person traveling near the speed of light appears to age slower than the twin on Earth and vice versa.

I don't get the whole vice versa part. Who actually ages more slowly?
