Here is the forward I got:

Mars


The Red Planet is about to be spectacular!

This month and next, Earth is catching up with Mars in an encounter that
will culminate in the closest approach between the two planets in
recorded history. The next time Mars may come this close is
in 2287. Due to the way Jupiter's gravity tugs on
Mars and perturbs its orbit, astronomers can only be
certain that Mars has not come this close to Earth
in the Last 5,000 years, but it may be as long as
60,000 years before it happens again.

The encounter will culminate on August 27th when
Mars comes to within 34,649,589 miles of Earth and
will be (next to the moon) the brightest object in
the night sky. It will attain a magnitude of -2.9
and will appear 25.11 arc seconds wide. At a modest
75-power magnification


Mars will look as large as the full moon to the naked eye.
Mars will be easy to spot. At the
beginning of August it will rise in the east at 10p.m.
and reach it

Scientists assume all sorts of things to explain how Big Bang occured such as Hyper-Space,Multi-Dimensional Space,Multiple Universes,..Etc Which can't even be proved atleast in de near future. Its de same case even with other models. Under science we can assume a theory as valid as long as it satisfactorily explains a natural phenomenon and till someone proves it wrong.. So now whats the problem for the scientific world if they assume that God caused the Big Bang..?? Because there is no reason to Disprove and Oppose it.. But some may argue "How did God come in the first place..?"Well.. Since Space-time began at Big Bang we can argue that since God created Space-Time..He is beyond time.. So u cant point to the time when God was formed.. Because if u try to do so u will be confining God within Time limits.. But he existed before time began for he himself was the creator of time at Big Bang..!!So since he is beyond time we can argue that he was never created but He always existed..!

Is not the creation of God intersting, making complex things from simple objects and sometimes loosing control of it, like the chaoes theory of Ian Malcolm, the mathematician in the Jurassic park book.

My friends and I saw a small wind farm where we live in upstate New York and someone inquired why all the towers weren't spinning at the same time. One of my friends, who is known for telling the most outlandish stories, said they stop some of them to make the wind farms more effiecient because it prevents one tower from 'stealing' wind from another tower. Common sense, and an engineering degree, tells me this guy is a moron. I also did some searching online and found nothing about increasing efficiency by operating at half capacity. I guess this really isn't a question because I know he's an idiot but if there is anyone who works with these plants to back me up and confirm his stupidity that would be great. Thanks.

I've heard scientists say they dismiss the traditional idea of aliens traveling in a spaceship to get here because it would take too many light years. However, I believe there are other dimensions that could get them here very quickly and that they are living on Earth as we speak.

Let me make up a question:

A prototype is being tested. The research team would like to know how big of a jerk they can achieve. The pilot takes off and accelerates uniformly from the starting position at a rate that will cause his velocity to be 300 feet per second in exactly 10 seconds. When his velocity reaches 150 feet per second, he flips the test switch and his acceleration uniformly increases at a rate which will cause his velocity to reach 600 feet per second at the original 10 second mark. What was the magnitude of the jerk?

In an ideal, 100% efficient transformer with a single primary and a single secondary winding, the general relations are:
Vp*Ns = Vs*Np (voltage stepping relation)
Vp*Ip=Vs*Is, (power relation)
where V are voltages, I are currents, N are coil turns, and p and s are subscripts identifying the primary and secondary coils, respectively.

How are the general relations modified in the case of multiple secondary windings?

part 1
By using the substitution u= sqroot(x+3), find the integration of (e^sqroot(x+3))/sqroot(x+3) wrt x.

part 2
Hence evaluate the integration of e^sqroot(x+3) wrt x, with integrals 0 to 1, giving ur answer in exact form.

Part 2 is the only part i need help in. so any help, even just by pointing me in the right direction would be appreciated. thanks
