| Physics (circular motion)? | | There is a clever kitchen gadget for drying lettuce leaves after you wash them. It consists of a cylindrical container mounted so that it can be rotated about its axis by turning a hand crank. The outer wall of the cylinder is perforated with small holes. You put the wet leaves in the container and turn the crank to spin the water. The radius of the container is 12 cm. When the cylinder is rotating at 2.0 revolutions per second, what is the magnitude of the centripetal acceleration at the outer wall? | |

| Did you ever have a fallout shelter at your home? | | I did. I just came across the picture that was taken with my mom, dad, cousin and I for the town newspaper, as my family was the first in our town to install a fallout shelter after the threat of nuclear war. It was in 1961, and I can still smell the shelter and remember the hand crank that you had to use to bring in fresh air. We had to climb down a ladder into it as it was installed in the back yard. Do you remember that time and did you have a fallout shelter? | |
| | Do you know/like angel cake? | | Angel food cake is a type of cake that became popular in the U.S. following the invention of the hand-crank egg-beater in the early 19th century.[1] It may also have been called angel cake. Because of its white color and airy lightness it was said to be the "food of the angels". A variety of Chocolate cake known as Devil's food cake is another popular American cake that was developed later[1] and was one of the many new American cakes made possible by the invention of baking powder. Angel food cake is a type of foam cake whereas the devil's food cake is a type of butter cake.Angel food cake requires that the egg whites be whipped until they are stiff, and gently folded into the other ingredients. For this method of leavening to work well, it is useful to have flour that has been made of softer wheat. This — and the lack of fat — causes angel food cake to have a very light texture and taste. It has led some detractors to liken the taste of the cake, as well as its appearance, to cotton. Angel food cake should be cut with a serrated knife, as a solid blade tends to compress the cake rather than slice it. Forks, electric serrated knives, special tined cutters or a strong thread... | |

| One Laptop Per Child | | There is a budding program that is attempting to get a laptop computer into the hands of every child on the planet and get him or her connected to the Internet. The idea is that educating children via the Internet is cheaper in the long run than using text books.
*
These laptop computers are not like the computers we use in America and in most other countries with easy electrical supplies.
*
One computer model has a hand crank system and is easily readable in sunlight. They have tiny storage capacity. Their rabbit ears are Wi-Fi and they use each other to connect to the Internet and the hub.
*
The program is doing well in Cambodia.
*
The pictured laptop runs Linux software. However, other companies are hopping on to this bandwagon, and a fast Google will find you lots of data on the subject. The days of students lugging around massive and heavy backpacks may in fact be... | |
