Philip was enjoying the second...

Philip was enjoying the second week of a two-week vacation the same way he had enjoyed the first week: by doing as little as possible.
He ignored his wife Paula's not-so-subtle hints about completing certain jobs around the house, but Philip didn't realize how much this bothered her until the clothes dryer refused to work, the iron shorted and the sewing machine motor burned out in the middle of a seam. The final straw came when she plugged in the vacuum cleaner and nothing happened.
Paula looked so stricken that he had to offer some consolation.
"That's OK, darling," Philip said. "You still have me."
Paula looked up at him with tears in her eyes. "Yes, Philip," she wailed, "but you don't work either."

Goddard's first rocket patent

In 1914, Robert Goddard, age 31,was issued a U.S. patent, the first of the 214 he would obtain in his lifetime as a pioneer rocket scientist. This patent was for a “Rocket Apparatus” (U.S. No. 1,102,653) which described the multi-stage rocket concept. A liquid-fueled rocket design was issued a patent the following week, on 14 Jul 1914, also titled “Rocket Apparatus.” It described a combustion chamber, with expander nozzle, into which liquid fuels are pumped. This was his second rocket patent. On 16 Mar 1926, his test launch, the first ever of a liquid-fuelled rocket, managed to propel a 10-ft long projectile to a height of 41-ft (12.5m). Its 2.5 second flight covered a distance of 184-ft at an average speed of 60-mph. The fuel was a combination of liquid oxygen and gasoline.«
