高科技：猫+黄油土司=反重力

musteryu

猫掉下来的时候总是脚着地..
烤面包掉下来的时候总是摸了黄油的一面着地..

只要把烤面包和猫绑在一起扔出去..就可以产生一种简易的反重力悬浮装置….

这个毫无根据
另外那个图外链失效~

这是某年搞笑诺贝尔的物理奖得主，还是有一定依据的。

Why Toast Falls Butter Side Down

Many have taken Sod's Law as the root causal factor for why toast always falls butter side down. This is incorrect. The real answer lies in simple physics. A falling piece of bread is influenced by several factors. The major one is gravity. The second and often overlooked one is height of the standard kitchen counter. The third factor is the size of the bread. The fourth and final factor1 is the angle at which the bread initially leaves its starting position. Most falling bread falls either to the left or the right. Rarely does a person hold both sides of the bread level with the ground and simultaneously drop it from both hands at the same instant. Instead, one is usually balancing the aforementioned bread slice in one hand and a bread knife in the other.

A Period of Rotation

The angle imparted by the ungainly divestiture of the bread causes the bread to rotate as it falls, fuelled somewhat by the uneven mass distribution of the butter or other viscous substance (ugh! like Marmite) on the bread or toast slice. This rotation has a period and unfortunately the floor intersects this cycle exactly at the half way point, resulting in the deposition of the bread slice with the viscous side down. If the counter top were twice as high, the bread would land butter side up 95% of the time. You can check this with a ladder in your kitchen and drop bread missiles from it. If you haven't a ladder handy, cut the bread in fourths or use a saltine cracker and drop from normal counter height. You can see that the cracker has a different period of rotation due to its smaller size, and should be able to complete a full rotation before hitting the floor.

Sage Advice

Do not ask your spouse for permission to conduct this experiment in your kitchen. Remember that it is better to ask for forgiveness than to ask for permission.

TV presenters Adam Savage and Jamie Hyneman carried out the experiment for science show Mythbusters.

They explained: "Our research showed slices landing butter side up had been pressed in from the buttering, forming a sort of dish in the bread. It is similar to when a leaf falls from a tree - it will always have a tendency to land with the curved sides up."

The pair built a mechanism which replicated toast accidentally being knocked off a table for the Discovery Channel programme.

And by using a thermometer, they made sure each slice was at exactly the same temperature.

A show spokesman said: "The Mythbusters team has tested a lot of theories, but this is the first time it has discovered how to beat Sod's Law."

这两段基本就是在说面包抹了黄油的一面着地并非是由于墨菲定律（即文中的Sod's Law，墨菲定律的另一个名称），而是有物理的解释
