I can stay at home for 3-4 weeks.I don't have other things to do,I am considering learning some linear algebra on my own.
Is it possible?easy?
is the time enough?

I downloaded a book from http://www.math.miami.edu/~ec/book/

it's copyrighted but free

The poles around here have been buzzing since I went outside today. This evening I saw they were all arcing across the insulators. I've messed with St. Elmo's fire before, and its nothing like that.

One question about evolution really got me. What is a process in which the information of the genome increases? I can't think of any common mutations, and I don't think natural selection would do it.

Cause with 1 and 2 you have less chance of missing a number randomly.

But with 1 2 3 you could and do get two numbers more often then the 3rd. Statisically if the world worked 100% of the time you would roll all three numbers before rolling the same number twice.

Here are the numbers I got:

2,2,3,2,3,1, 2,3,3,1,2,3,2,2,2,3

How come luck ran out on the 1? Is there something about it being on odd number????

This happened almost consistently for two hours with an occasional two 1's in a roll.

I was wondering if there is some mathatical theory to this?

Also I tried it on a different day and 3 was the least number rolled

THERE ARE 4 WEATHER FRONTS used by meteorologist. list the 4 types.

using the following data, determine which two fronts are described. what other characteristics about these two fronts could be added to the ones provided for you?
data front a: (1) ahead of the front the air is warm and moist (2) a sudden temperature change has occurred and (3) a thunderstorm has formed along the front.

data front b: (1) there is a gentle slope between two air masses (2) stratus clouds have formed and (3) there will be an increase in temperature when the front passes

I'm confused on the whole line between a pharmacist and a physician. At a pharmacy, are the drugs already on hand? That doesn't seem plausible, considering how many drugs there are. So does a pharmacist actually make the drugs? Whats the acutal process they go through? If the merely put the drugs in the bottle, why do they have to go through so much schooling? I understand how sensitive it is, and how a mistake can be fatal, but just a few more years and you could be a doctor.

as 1 astronomical unit (au). The mean radius of the Moon orbit around the Earth is 0.002570 au. The mean radius of the Earth at the equator is 6378 km. The distance from the Earth of the Moon is equivalent of how many trips around the circumference of the Earth of the equator? thanks!

A stationary 0.1-g fly encounters the windshield of a 1400-kg automobile traveling at 120 km/h. (a) What is the magnitude of change in momentum of the car due to the fly? (b) What is the magnitude of change of momentum of the fly due to the car? (c) Approximately how many flies does it take to reduce the car's speed by 1 km/h?

For a), I got that

0.1g/1000g=0.0001kg

0.0001kg*120km/hr=0.12kg*km/hr

But I don't know how to get b and c...

Okay let's try a hard question for a change.

What is the volume of intersection of two pipes whose center axes intersect each other at a perfect right angle, and whose inner diameters are 1 meter? That is, what is the total volume of the set of points which are enclosed by both pipes at the same time?

Hint. Consider the pipes as the equations z^2+x^2=0.25 and z^2+y^2=0.25 .

For example, if I was to have a truck weighing 6578 pounds on a driveway inclined at 17.5 degrees, what's the magnitude of the force required to keep the truck still?

I do know that the force of gravity on the truck is 6578sin(17.5), but I have no idea on how to find the force required to counteract the gravity.

There has been this story going around myspace and the news about a little boy named kaleb.
His babysitter shook him and he has shaken baby syndrome.
From what I understand it causes brain damage.
But this baby is having other problems like infections, seizures, vomiting, and other things.
How can all these horrible things be caused by shaking a baby?
Please pray for the family.

The name of our galaxy is the Milky Way Galaxy, but what is the name of our solar system. I know that the sun and our solar system are located within the Orion Arm, but every book I read referes to our solar system as The Solar System. Hhmm maybe that's the name of it and to think we name everything on and off our planet but our very own solar system.
