A fascinating article that outlines what might have triggered the ‘Ever Given’ to get stuck in the Suez canal.
Lataire wrote his dissertation on a similar phenomenon as a ship passes close to a bank: the bank effect. The water speeds up, the pressure drops, the stern pulls into the bank and, particularly in shallow water, the bow gets pushed away. Stern one way, bow the other. A boat that had been steaming is suddenly spinning. It’s a well-identified phenomenon; in 2009 Ghent University’s Shallow Water Knowledge Centre put together a whole conference about it. Clever pilots on the Elbe, according to Lataire, will use it to shoot around a bend.
However: the more water a ship displaces, the stronger the effect. And the closer the side of the hull is to the shore, the stronger the effect. The bigger the ship, the faster the bow shoots away from the bank.
@tnpoliceoffl What would it take for you to legalize or make it mandatory for all ambulances to drive on the opposite direction of traffic flow? I’ve seen this in Uganda and it’s amazing how swift they’re able to beat the traffic. Oncoming traffic has no option but to make way.March 27, 2021 06:09
An interesting point on M1 and M2 [Measures of money]. With the signing of the 1.9T$ bill today in the US, we’ve essentially created 6T$ over the last 10 months. Just like that…
Covid19 has brought unprecedented suffering to many. Deaths, Unemployment, Medical complications, lifestyle changes, Social unrest and several other ramifications which we are yet to experience. If anything, it has
taught us highlighted how abysmally poor we are in collectively addressing pressing issues. It has also shown us that when disaster strikes, we only take care of our own and we are selectively biased even at that. Nature gave us yet another opportunity to show how we could better ourselves and elevate us to the next stage of evolution and we miserably failed. With our myopic non-collaborative actions, pushing politics and power over general good, we’ve defined a new low. Mileage on isolated or individual efforts unfortunately does not carry the ripple effect that can scale. Nothing surprising there – Humans are selfish creatures. We of course needed something to balance all the intelligence and cognitive advances we supposedly have over other living things. Humanity rests is constant chaos and Covid19 was continues to fuel that chaos.
Quite a digression, eh?
So last April the Fed changed the rules and eliminated the six-withdrawal limit on savings accounts. It wrote:
The interim final rule allows depository institutions immediately to suspend enforcement of the six transfer limit and to allow their customers to make an unlimited number of convenient transfers and withdrawals from their savings deposits at a time when financial events associated with the coronavirus pandemic have made such access more urgent.
It was an obvious and nearly risk-free way to help people. Just let them have easier access to their savings.
But it changed the relationship between M1 and M2.
Another brilliant piece from Nate DiMeo. Close to 70 years now and sadly there’s still so much to fight for to get to a level field!
A note on notes: We’d much rather you just went into each episode of The Memory Palace cold. And just let the story take you where it well. So, we don’t…
