Random News not worthy of own thread

As has already been anticipated by seismics and ground mevement, the Fagrawhatever (lost the copy buffer ) volcano on Iceland has started to erupt. I only find stupid news items for now, but I'll keep half an eye on it for when there's something official.

Edit: Fagradalsfjall. Don't drink and speak . Unlikely to elvolve into an explosive eruption

This is not much in the way of a news article, but it's a rather cool piece of video of the eruption.

[BaronVerde]

Cool indeed

The number of people wandering casually around the leading edge of the lava flows is... interesting.

[felter]

When I posted the link earlier, there was a helicopter parked right where the bottom of the lava edge is now, so it is definitely growing and it's interesting watching a new mountain being born. I suspect a lot of the ones wandering around the edge, were/are scientists and monitors but I bet there are more than a few idiot tourists too.

[BaronVerde]

Yeah, they seem to know what they are doing, and when sulphurous air may become a problem.

This seems to be a purely effusive eruption, and this morning it was said it's weakening for the moment. From gases and lava composition one can say if there a risk of an explosion. Of course, if seawater reaches the magma, that'll be a bad day, but there seems to be no imminent danger for now.

Toronto-based designer, artist and architect Krista Kim created a virtual home on Mars and sold it for real money. Initially, she asked for 30 Ethereum, but as a result of the auction, she received 288 Ethereum, which is now equivalent to $ 515,459.

There are a lot of dynamic forces acting on a ship in such an environment. My bet: though they blame winds, I think they were a bit too fast underway. Just 1 little knot, water on side passing faster than on the other, and no rudder is stronger than Bernoulli

I would be surprised if a ship that big using the Canal would not have had a professional Canal pilot. Whilst I do think that it probably was mostly down to wind conditions, I'm surprised that there isn't some sort of control mechanism for such high and large slab vessels during forecast adverse winds. Rather like that for high-sided vehicles going over some exposed suspension bridges during high crosswind conditions.

Yeah, I too think there is a large set of procedures to follow, including licensing, piloting, ship spacing and ordering, traffic control and supervision etc. I wouldn't assume that a ship just enters and sails through. It is a narrow path, there isn't much water under the keel and at the sides, it is highly 'bernoullic', humorously said. Once things go dynamic not even a divine intervention will help

There'll surely be an accident report, on day.

Edit: Yes, there are a few rules to observe https://www.suezcanal.gov.eg/English/Na ... ation.aspx

The ship in question apparently has a sizeable bulbous bow (this isn't the same ship, but it appears to be the same design, and you can see the bow on the Ever Stuck Given here:

If anything, going too *slowly* would be an issue more than going too quickly--there's a minimum speed the ship has to be travelling at (called "steerage way") for the rudder to work effectively.

True for the open water, but that speed is very low, those boats have thrusters, and here we're talking about confinement in narrow waterways with their own dynamics. Or, in short, when going too fast the rudder won't save you, if it is moveable at all even by the hydraulics against the dynamic forces created by pressure waves and waterflow.

Example text: http://www.porousmedia.nl/nfcmr/natuur/ ... 0ships.pdf

A lot of work has been done on this. And the video below shows how 'convincing' the dynamics can be to ships passing at too high speeds edit in confined waterways. Similar accidents, including collisions with embankment, are frequently in the accident reports of collisions in narrow waterways and canals.

Here the pressure waves between the hulls and the banks in conjunction with accelerated flow between the ships causes a colliosion, and not even the high speed of that Hapag Lloyd ship makes the rudder effective. They were just too fast (probably because of failures that happened before the weird maneuver).

The Event Horizon Telescope (those guys who made an interferometer the size of the earth and published the first image of the direct vicinity of a black hole) has published the first ever visualisation of the magnetic field near that same black hole. This helps understand how a region the size of the solar system can produce gas jets that extend 10s of thousands of light years into space.

Isn't there a system in X4 with an accretion disk and a swirling jet ?

SCA said it could take days and up to a week to free the stuck ship.

Surprised nobody has posted about this but LHC results could hint at the discovery of lepto-quarks: https://www.bbc.co.uk/news/science-environment-56491033

Eh, it's three sigma. It could end up being something super exciting, sure, and there have been other experimental results in the past vaguely hinting in the same direction, but three sigma results in particle physics disappear a lot. (I'm reminded in particular here of the 750GeV bump from a few years back, and that one was nearly 4 sigma when it was announced.) I sort of get the impression that a combination of hints of this particular sort of symmetry violation having existed for a while, plus it being lockdown and everyone desperately looking for good news, have produced a little bit more excitement than is really justified by the evidence at this point. I do of course hope it does survive with more evidence, but I'm reserving my excitement until that happens.

[berth]

Yeah, agreed. Hence I didn't start a new thread
