In one twenty-ninth of a second you pass over one yard.

Now, one yard is quite an appreciable distance, but one twenty-ninth of a second is a period which cannot be appreciated.
The father of the Webster brothers, before going away to be gone for a week, gave his boys a stint to cut a field of corn, telling them that after it was done, if they had any time left, they might do what they pleased.

The boys looked the field over on Monday morning and concluded they could do all the work in three days, so they decided to play the first three days.

Thursday morning they went to the field, but it looked so much larger than it did on Monday morning, that they decided they could not possibly do it in three days, and rather than not do it all, they would not touch it.

When the angry father returned, he called Ezekiel to him and asked him why they had not harvested the corn.
