Will you marry me?

There were these two elderly people living in a Florida mobile home park. He was a widower and she a widow. They had known one another for a number of years. Now, one evening there was a community supper in the big activity center. These two were at the same table, across from one another. As the meal went on, he made a few admiring glances at her and finally gathered up his courage to ask her, "Will you marry me?"

After a dramatic pause and precisely six seconds of 'careful consideration,' she answered. "Yes. Yes, I will."

The meal ended and with a few more pleasant exchanges and they went to their respective places.

Next morning, he was troubled. "Did she say 'yes' or did she say 'no'?"

He couldn't remember. Try as he would, he just could not recall. Not even a faint memory. With trepidation, he went to the telephone and called her.

First, he explained to her that he didn't remember as well as he used to. Then he reviewed the lovely evening past. As he gained a little more courage, he then inquired of her, "When I asked if you would marry me, did you say 'Yes' or did you say 'No'?"

He was delighted to hear her say, "Why, I said, 'Yes, yes I will' and I meant it with all my heart."

Then she continued, "And I am so glad that you called, because I couldn't remember who had asked me."

Atomic nucleus recoil

In 1904, a letter in the journal Nature*, Harriet Brooks pointed out a peculiar type of volatility shown by an active deposit of radium immediately after its removal from the emanation. Hahn and Russ and Markower later showed (1909) that “the effect was due to the recoil of radium B from the active surface accompanying the expulsion of an alpha-particle from Radium A. This method of the separation of the elements by recoils ultimately proved of much importance in disentangling the complicated series of changes in the radioactive bodies,”according to Ernest Rutherford (1933). Thus, Harriet Brooks was probably the first person to observe the recoil of the atomic nucleus as nuclear particles were emitted during radioactive decay.(*vol. 70, p. 270)
