I found some interesting info on the tides in the Chesapeake Bay. The Bays being an estuary has fresh water coming in at one end and seawater coming in at the other and being 200 miles long has currents coming and going at the same time the water will slosh back and forth. But more importantly...

I've tried hard but could not find any data near the Key bridge. However, the tides in the Bay East of the bridge at that date and time are estimated to be about 0.6 kt southward. However, I found out that the wind speed at the Key Bridge from a NOAA website was about 11 Kts SSE. at the time...

Hmmm,I can't seem to remember what I was doing at 16.

The graph indicates that the BS grads not going to grad school had a 13% unemployment rate. :))

Still, philosophers are more employable than physicists., Really? By the way, Buc-ees the world's largest gas station and convenience store will pay $22/hr to clean restrooms. I this where they are going? Maybe philosophers are just realists and take what they can while physicists are too...

Bow thrusters provide lateral thrust and are used to maneuver ships in tight quarters. See https://www.marineinsight.com/marine-navigation/how-bow-thruster-is-used-for-maneuvering-a-ship/#:~:text=The%20power%20of%20the%20bow,(11%20knots)%20while%20berthing. for details

There are a few companies that are using a different approach to AI, one is Verses AI. From their website:https://www.verses.ai/rd-overview They believe that they can achieve AGI in two years. Their current AI agent GENIUS is anticipated to be available to the public by the end of this year...

Unless something is changing rudder corrections are not needed when running down a straight fairway. Regarding the bank effect We do not know how big it was if it was a factor. I estimated that the ship if in mid-channel was 30 yds from the marked channel edge and an additional 45 yds from...

The ship was on a constant heading down the channel (or should have) when the power went out. If the rudder was locked then it should have continued undeviated down the channel. It did not. It was less than one hour before slack water on that date. The high water mark was only 1.09 feet and...

There is a lot of ship underwater to resist such a motion and it would take a substantial wind to move the ship a significant amount in 4 min. Also typically a night the wind is usually light, especially in a harbor. About current I doubt there is a significant cross-current in the channel...

According to this survey, you have a better chance of getting a job with a Philosophy degree? Physics seems to be the low man on the totem pole for science degrees. I'm not sure about these numbers.

There was a post on the internet shortly after the accident by a former containership captain who said that he always had a drill for loss of engine or electrical power when leaving port. Such occurrences IIRC are not rare. He also said the first thing he does on loss of engine power is drop...

One of the problems that I observed in the early years of management engineering was their ineffectiveness because of the lack of knowledge of the domain in which they were working. They had all the skills for solving problems like inefficiencies, cost reduction, etc but were stymied and...
