      3 pieces. Break a cookie in half 2 times.
      • Break #1: 1 = 0.5 + 0.5
      • Break #2: 1 = 0.5 + 0.25 + 0.25

      3 pieces. Not 4. You would need 3 breaks to get 4 pieces.

        You can't break a cookie in half twice. You can break it in half once and then you can break a half-cookie in half. Saying that you're breaking the [whole] cookie in half twice implies that you are making the first break and then breaking both of those halves in two.

          There are no half-cookies. There are only cookies. Some are small; some are big. It's like saying there are half rocks. Divide a rock in half, u get 2 rocks. Not 2 half rocks. This is because a cookie has no anatomy as you and I would know it. It is symmetrical and the independent of scale. It applies down to a cookie of size 2 molecules. A 1 molecule cookie cannot be divided, because dividing molecule yields entirely different substances.

          If I had said an "apple", that would have been different. Half apples do indeed exist.

              It does not work for cars because cookies and rocks have a property that cars do not--symmetry of matter. Materialwise, they are consistent. Imagine a plane slicing through a rock dividing it into two--slicing at any angle. The material on both sides of the plane will always be of the same type of material possessing the same properties. This is why a rock sliced in half results in 2 rocks--not 2 half rocks. That is not true for cars because I can slice only the tire and have rubber on one side and the rema

                  Obviously the cookie is made of an exotic form of matter. Other substances, like water or salt, can be divided almost indefinitely (until you get down to a single molecule) without losing their properties. Not so with cookie matter. A chocolate chip cookie can be broken down only so far before it ceases being a chocolate chip cookie, and becomes just a plain cookie. This can happen even at centimetre scales. Some cookies have a directionality to them. Oreos, for example, when broken radially maintain

      Looking at the headline, you would think this new ocean were poised to spring into existance in a sudden burst of volcanic chaos. In human terms, that's clearly not what we're looking at - they're talking about a million-year process.

      The clear conclusion is that this story was written by an entity with a much courser view of time than our own. Sure, 40 years sounds like old news to you, but to them it must be a blink of an eye. Barely enough time to bring the information to press, even.

  • new news is always old news when you look for science in everyday magazines/newspapers. Anyway, I remember knowing from somewhere (school, discovery, whatever) that Africa is due for another splitting in some millions of years (the great lakes are just rifts filled with water from what I remember) I found this webpage http://www.see.leeds.ac.uk/afar/ [leeds.ac.uk] the new news is at least a few months old. maybe the news is just that they published an article about it.
    • by mrboyd (1211932)
      The news is not that there's a rift of about 6000km long. Other people had noticed that. The news is that some very specific stuff that mere human don't give a frack about may happen there. Of course since I'm not a geologist I have no clue why it matters; if it's news or only news for that particular location or quack science.

      For the first time they demonstrate that activity on one rift segment can trigger a major episode of magma injection and associated deformation on a neighbouring segment.

      The great lakes wereformed from glaciers during the last ice age. This is more like the midAtlantic ridge. Once it reaches an ocean it will flood and we no longer will have to worry about global flooding from melting glaceirs.
