Abe and Esther are flying to ...
Abe and Esther are flying to Australia for a two-week vacation to celebrate their 40th anniversary. Suddenly, over the public address system the Captain announced, "Ladies and Gentlemen, I am afraid I have some very bad news. Our engines have ceased functioning and we will attempt an emergency landing. Luckily, I see an uncharted island below us and we should be able to land on the beach. However, the odds are that we may never be rescued and will have to live on the island for the rest of our lives!"
Thanks to the skill of the flight crew, the plane lands safely on the island. An hour later Abe turns to his wife and asks, "Esther, did we pay our $5,000 PBS pledge check yet?"
"No, sweetheart," she responds.
Abe, still shaken from the crash landing, then asks, "Esther, did we pay our American Express card yet?"
"Oh, no! I'm sorry. I forgot to send the check," she says.
"One last thing, Esther. Did you remember to send checks for the Visa and MasterCard this month?" he asks.
"Oh, forgive me, Abie," begged Esther, "I didn't send that one, either."
Abe grabs her and gives her the biggest kiss in 40 years.
Esther pulls away and asks, "What was that for?"
Abe answers, "They'll find us!"

SunspotsIn 1611, a publication on the newly discovered phenomenon of sunspots was dedicated. Narratio de maculis in sole observatis et apparente earum cum sole conversione. (“Narration on Spots Observed on the Sun and their Apparent Rotation with the Sun”). This first publication on such observations, was the work of Johannes Fabricius, a Dutch astronomer who was perhaps the first ever to observe sunspots. On 9 Mar 1611, at dawn, Johannes had used his telescope to view the rising sun and had seen several dark spots on it. He called his father to investigate this new phenomenon with him. The brightness of the Sun's center was very painful, and the two quickly switched to a projection method by means of a camera obscura. |
