The arguments being these:
1) Let n=.999...
100n=99.999....
100n - n = 99
99n = 99
n = 1 = .999....?

or how about this?
2) 1/9 = .1111....
2/9 = .2222....
3/9 = .3333....
4/9 = .4444....
..
..
8/9 = .8888....
9/9 = .9999.... = 1?

Yes or No?

A ton of iron, how much does it weigh at the Earth's center? Or a cubic meter of iron or lead? Or a cubic meter of whatever stuff that is now there at the very center?

Please note: According to raw data, a total of 2,727,233 similar questions have been asked so far (in the U.S. alone) -- but similar how? And where are the answers? And were any of the questions so similar as to be exact to this one?

I want the answer to this exact question, but also in a broader sense I'm interested in many similar questions. It's all very exciting, and so I have come to Yahoo-Answers in the spirit of exciting inquiry...

These mirrors were left behind by 3 seperate apollo missions. They have been used, on an almost daily basis by hundreds of observatories all over the world.
So, if you say (and trust me folks, there are people, and I kid you not, that believe, that people have never walked on the moon.
Yep, they really are this stupid.
They believe that the greatest feat of engineering in the history of mankind, was faked on a movie studio in Texas somewhere.
Hey, these are THIER words, not mine.
But when it comes to the retroreflector arrays, they are strangely silent. Why is that?
Because it proves man went to the moon. Repeatedly.
So, I'd like to hear some theories about how the reflectors got there.
(In case you don't know the retroreflectors may be the most important thing the Apollo missions left behind. They are simple devices, just three part mirrors that reflect back a lazer beam. With this unit we can determine the distance from earth to the moon to within 3 centimeters)
So, let's hear it...

It's a hot afternoon; you've just finished mowing the lawn and are in need of a nice, cold beer. Prior to starting your yard work, you put the beer in the freezer so it would be very cold — and refreshing — when you were ready to drink it. You take the beer from the freezer, and it is indeed very cold (but not frozen). But before drinking it, you add a little lime juice. All of a sudden, ice crystals form and work their way down through the beer. What happened?



(I'll post the answer in ten minutes, so check back after you've replied)

okay according to the law of relativity the mass of a body increases when it is traveling at great velocities.. Lets just say that an object is travelin at da speed of light which means dat the mass of the object according to the equation becomes infinite.. if this is so the gravitional field around the body should all so be infinite (F=GMm) so basically v cant travel at that speed...n all electromagnetic waves travel at the speed of light so will this object become an electromagnetic wave or sumthing else or remain unchanged.. help wth dis will u..

At birth? At conception? At the beginning of time? At the foundation of the world? Or at some other time?
Each individual human soul is created separately, or were they all created together?
Finally, if the human soul is created long before birth on Earth, where does it reside in the meantime?
This is a question for a scientific paper, so please no funny answers.

There's a small Irish high-tech company claiming they discovered a way of creating unlimited free energy. That goes against one of our most fundamental ways of understanding the universe: the principle of conservation of energy that says 'energy can neither be created nor destroyed, it can only change form.'

If they are right it means we would never have to recharge our mobile phones or refuel our cars.

They challenged the scientific community to prove them wrong

The Challenge was published in The Economist magazine.

Here's the link to the company:

Here's the news from an accredited media source:
http://www.guardian.co.uk/science/story/0,,1854394,00.html

I am very sceptical about their claim, but if they are right this would be the most bombastic discovery in human history, it would change global economy forever.

What do you think?
