Folding Paper in Half 12 Times: impossible?
January 21st, 2011
Even After reading this I still don’t quite understand.
Britney Gallivan has solved the Paper Folding Problem. This well known challenge was to fold paper in half more than seven or eight times, using paper of any size or shape.
In April of 2005 Britney’s accomplishment was mentioned on the prime time CBS television show Numb3rs.
The task was commonly known to be impossible. Over the years the problem has been discussed by many people, including mathematicians and has been demonstrated to be impossible on TV.
For extra credit in a math class Britney was given the challenge to fold anything in half 12 times. After extensive experimentation, she folded a sheet of gold foil 12 times, breaking the record. This was using alternate directions of folding. But, the challenge was then redefined to fold a piece of paper. She studied the problem and was the first person to realize the basic cause for the limits. She then derived the folding limit equation for any given dimension. Limiting equations were derived for the case of folding in alternate directions and for the case of folding in a single direction using a long strip of paper. The merits of both folding approaches are discussed, but for high numbers of folds, single direction folding requires less paper.
The exact limit for single direction folding case was derived, based on the accumulative limiting effects induced by every fold in the folding process.
For the single direction folding case the exact limiting equation is:

How to… make toast.

How to Make Toast
from wikiHow – The How to Manual That You Can Edit
Toast can be made with any type of bread, but the favorite seems to be white bread.
Steps
- Choose the kind of bread you wish to use. You can use just a regular white bread, or a specialty bread like rye, whole wheat, brown or french.
- Using a ‘bread’ knife slice your bread to fit the toaster unless it is already sliced for you.
- Carefully put your slices of bread into the bread slots of the toaster or rack of a toaster oven.
- Choose what settings to use. Use a lower setting to start out with until you’ve mastered the skills needed to handle the higher settings.
- Plug in the toaster.
- Push down the toaster plunger to turn it on.
- Wearing an oven mitt, carefully remove the hot toast from the toaster after it pops up. Unless it jumps out itself, like mine usually does.
- Place the toast on a plate, remove your oven mitt and spread toast with butter, peanut butter, jam or whatever you prefer on one side.
- Slice in half, quarters, or leave whole.
- And now that you have gone through all that, don’t forget to eat your toast!
- Unplug the toaster.
- Clean up your mess and put away the things you use. Enjoy!
Tips
- Be careful with which setting you use. If you do not know what setting to use refer to your toaster manual for help. If you use too high a setting, you may burn your lips on the hot toast, and then you will have to rush to the Emergency Room of your nearest hospital.
- If you burn the toast, you can still fix it. Take the flat side of a butter knife and scrape off the burned crumbs; be sure to do this over a trash can, as this makes a mess. But, if the whole bread is totally burned, make another one. This is why you must practice first on the lower settings of the toaster. Remember, practice makes perfect toast.
- If you use butter, spread it on the bread as quickly as you can after the bread comes out of the toaster. This way, the butter melts into the bread and it is easier to spread because the toast is still hot.
- Never put your sliced bread in the freezer. Instead, keep bread in a bread box, which will keep it fresh and the toast will taste better.
Warnings
- Don’t stick your hand/fingers into the toaster. You will get burnt and could get electrocuted.
- Don’t get your toaster or the toasters cord anywhere near water. It could be very dangerous.
- Don’t use a knife to get the toast out if it’s stuck, as it is also very dangerous.
Things You’ll Need
- Bread
- Bread knife (for unsliced bread)
- Toaster
- Butter (optional)
- Butter knife (optional)
- Oven Mitts (optional)

How glass is made
February 17th, 2009
This is amazing, how glass is made:
Most glass is a mixture of a large amount of silica that comes from fine white sand or pulverized sandstone, combined with smaller amounts of an alkali like soda (sodium bicarbonate) or potash to lower its melting point, and lime (from limestone) to help stabilize the mixture and ultimately make the glass stronger and water-resistant. These elements are naturally occurring throughout North America.
