I've got so much good stuff to remember. I want to remember it all right now, but I don't see how I could mentally handle that. It reminds me of a U.S. Navy warship maneuver called an “emergency crashback.” That is where the bridge orders the engines into full reverse as the ship is traveling forward and it can be a rather dramatic maneuver.
Propeller Crashback
Imagine a large ship steaming at full speed. Suddenly, the ship needs to stop or turn, and the captain throws the propeller into full reverse. This dramatic reversal produces large fluctuating forces that can sometimes break a propeller blade or impair the ability to steer the vessel.
While current engineering methods are adequate to simulate a propeller operating under normal design conditions, they are inadequate to model the unsteadiness in blade forces encountered in experiments and the real-world emergency crashback maneuver. To give engineers a simulation approach that can capture the full complexity of propeller crashback and help them predict required blade strength, Mahesh and graduate student Martin Vysohlid, supported by the Office of Naval Research, are performing Large-Eddy Simulations (LES) of the complex geometry and the 3-D flow around a reversing propeller. The simulations show low-frequency unsteadiness similar to what is observed in experiments, and torque and thrust coefficients significantly closer to experimental values than previous methods.
This project demonstrates the potential of Mahesh's simulation methodology to predict off-design conditions in marine environments, and the researchers plan to extend this work to investigating another hard-to-predict problem, blade cavitation, the disruptive bubbles that can form and collapse on propellers under extreme conditions.
I can't "remember" the year Tracie was born, but the age difference with Phoebe is about right. Tracie was no more than 5 years younger than Kerry Burgess. Phoebe is 4 years, 4 months, 13 days, younger than I am in my real identity. That's 4 years, 4.433 months. As I “remember” it, Tracie and I did get divorced, but then, Tracie was no Phoebe Cates. She definitely seems to be the woman I want to go to after surviving whatever new nightmare the terrorists throw at me at any given time. Certainly this is not just some trick to leave me disappointed. Certainly it will turn out that I will get her back soon. Why not today????
Reading the linked article, with excerpts below, reminds me of a "memory" of standing in our workshop at First Federal and Jim Shea was angry because I had hung up on him on the telephone. We were working a lot and the tension was getting high because of the work load. I was carrying a disk drive, which was about the size of a toaster, and I can still remember that I was wearing my Wayfarer sunglasses because I was on my way out to a bank branch on a service call. I told someone later that I was tempted to hit him upside the head with that disk drive. Who knows what that "memory" actually represents. I have no idea. It's all quite fascinating. Excerpt that I wish I could sit around feeling fascinated by my wife.
Reagan’s private, dramatic musings revealed
Excerpts of former president’s diary released in Vanity Fair
Updated: 6:02 p.m. PT May 1, 2007
NEW YORK - Ronald Reagan saved his most private and dramatic thoughts for a handwritten book — a diary in which he recalled his running frustration with the Israeli invasion of Lebanon, his fear that Armageddon was near and coughing up blood on the day he was shot.
Diary excerpts, released by Vanity Fair magazine on Tuesday, also reflect on the troubled relationship he had with his son Ron, his preoccupation with the "mad clown" Libyan leader Moammar Gadhafi and his personal chemistry with Mikhail Gorbachev during arms-control talks.
Reagan hand-wrote diary entries every day of his eight years in office from 1981 to 1989 except for when he was in the hospital after being shot on March 30, 1981, about which he wrote, "Getting shot hurts."
...
Events in the Middle East concerned him so much that Reagan wrote on May 15, 1981, "Sometimes I wonder if we are destined to witness Armageddon."
Then on June 7: "Got word of Israel bombing of Iraq — nuclear reactor. I swear I believe Armageddon is near."
...
He said one particularly devastating bombing and artillery attack on western Beirut in August 1982 had led King Fahd of Saudi Arabia to call the White House "begging me to do something."
"I told him I was calling P.M. Begin immediately. And I did — I was angry — I told him it had to stop or our entire future relationship was endangered. I used the word holocaust deliberately & said the symbol of war was becoming a picture of a 7-month-old baby with its arms blown off."
There were lighter moments, such as the time Prince Charles — "a most likable person" — visited the White House.
"The ushers brought him tea — horror of horrors they served it our way with a tea bag in the cup." He said the prince admitted, "I didn't know what to do with it."
