i heard about this on Coast to Coast AM with Goergr Nory i copied and pasted this so you could read it. do you think its going to happen or is it just crap. they said they expect it to happen in the next 10 to 15 years its kind of freeking me out.
Cyclic global catastrophic events throughout our past have created permanent gaps in recorded human history and technology. The Horizon Project research team operated by Brent Miller believes they have uncovered overwhelming scientific evidence that shows this catastrophic event is about to occur once again. Our solar system is quickly approaching what scientific research and ancient records refer to as "The Dark Rift" or "The Galactic Plain". This will result in increased gravitational influences upon our solar system; causing global devastation and loss of life on Earth. Shockingly, evidence has been left behind throughout human history which provides dire warning to future civilizations; warnings that have been ignored

I am doing a simple lab (making soap) and one of the post-lab questions is to calculate the ratio of NaOH to triglycerides. I know the olive oil I used is a triglyceride, but I don't know if the Crisco I used is.

A ball is thrown upward from the top of a 60.0 m tall building. The ball's initial speed is 12.0 m/s. At the same instant, a person is running on the ground at a distance of 41.0 m from the building. What must be the average speed of the person if he is to catch the ball at the bottom of the building?

I've stuck at this question for half an hour now. All my book talks about is organic molecules and other stuff, but no inorganic molecules. It's part of my biology homework. And don't say to look for it myself. I've searched the internet, looked in my mom's college biology books but could not find anything! Please help!

Can someone help me with math?!?!?
How is the relationship between an inscribed angle and its intercepted arc different than that of a central angle and its intercepted arc?

Thanks SO much!

At the stroke of midnight on New Year's Eve 2006-2007, Amy had savings of $135 stored away. Starting on New Year's Day and for every day this year, Amy will put $1 into her savings. On every fifth day (first time: January 5) Amy will also add into her savings the $5 she receives for kitchen chores. On every seventh day (first time: January 7) Amy will withdraw $7 from her savings to pay her entry fee in the Really Very Hard Problems Math Contest. How much money will AMy have in her savings at the stroke of midnight on New Year's Eve 2007-2008?

Haha try it!

A car accelerates from 0mph to 35 mph. Its velocity at time t is v(t)=5t mph where t is in seconds. Use an integral to find the total distance in miles it travels during its acceleration. (Hint: work with seconds not hours.)

I'm a math major and need to find a project to make a presentation on. I'm a big sports fan so I'm looking for something that relates to math and sports (even more so baseball). Any ideas?

In our design and construction class, we have to design a small crash car that will hold 4 small 5/8" paintball passengers, and will then be run into a wall at speeds of 50-60 mph, on compressed carbon dioxide. The passengers should survive. Could someone either a) give me an idea as to what the basic design should be, or b) point me to a site that explains the physics of a car crash? And how to most effectively design a car?

I am taking a rather intense statistics class and I have a question about combinatorics.

This is just a general question to try to explain my problem.

There are 12 people to be assigned to 3 different teams Red, Blue, and Gold of 5, 4, and 3 people each. How many distinct teams can be formed.

The formula for answering would be (12 choose 5) * (7 choose 4) * (3 choose 3).

How do I use the math to work this problem out? and another question how can I work this out on my calculator?
