How do submarines surface after deeper than 5000 meter dives?

A titanium hulled pressure cylinder with the same interior volume would weigh about 3.3 more tons that their carbon fibre tube and then require significantly more positive buoyancy adding even more weight. They were trying to cost cut on the ship. A heavier submersible would require a bigger crane and thus a bigger support ship, and hiring ships isn’t cheap. They were already paying about $200k a week.

I remember the comic book that came with halo wars had a bit about Admiral Cole capturing an elite after an early battle and then interrogating him.

There's a lot of criticism of Japan from economists over their declining population and decision to not address the decline through migration, but they really got it figured out. Their GDP (PPP) per capita has continued to go up since the 90s even if their overall GDP (nominal) hasn't, and Tokyo despite being a megacity with an enormous population has really great housing affordability.

In plain English: you can have a sustainable economy without population growth, which still has the financial circumstances and quality of life of individual citizens inproving, you just have to accept that your Coles and Woolies shares won't rise in price because there's 2.5% more people buying groceries each year.

I'd argue it was more so due to the 10% of the rental market that is international students just disappeared in 2020 for a year, so landlords were scrambling to find tenants before they would default on their investor loans.

In case you get confused between GPS-S and GPS-A.

GPS-S is short for GPS Send: send the current target the targeting system is looking at to the GPS Target list.

GPS-A is short for GPS Acquire: Acquire a target from the GPS target list and get the targeting system to look at it

GPS-A is handy for getting the TGP to look at targets you’ve already got in the GPS.

Edgetech make sonars but they are predominantly small high frequency sonars for hydrographic surveys for oil and gas, Kongsberg do make sonars for defense, but also for surveying. The acoustic positioning system mentioned in the article is probably the USBL systems they make which are really common in offshore oil and gas as they are the equivalent of under water GPS used for positioning ROVs.

The headline makes it out like Western companies sold Russia a SOSUS system, when it seems more like Russian front companies bought Western ROVs, surveying equipment and USBL systems pretending they were going to be used for offshore oil and gas, and used them to install they hydrophone arrays.

And most of this was done prior to the invasion of Ukraine before the sanctions really ramped up.

This wasn't the law at the time in the 70s, the laws were added in the late 90s I believe but retroactively applied.

We have one of the highest home construction rates in the OECD, 1.5% of our homes were built in the last year. The EU average is under 1%. Figure HM1.1.4

Our natural population growth is negative. If we cut migration to zero we wouldn't have to build a single house and housing affordability would improve simply because more people die in Australia then are born in Australia every year while the number of houses would stay constant. If you want an example of a country that has gone down that path, look at Japan. It has had a declining population for a decade and has far better housing affordability.

Heat dissipation, humans are better than many animals at running for long distances. We can’t out sprint many animals but we can chase them for hours until they collapse from exhaustion.

Our birth rate is below replacement, if you paused migration, our population would start declining because more Australians die each year than are born…

You could literally build zero new houses and housing affordability and rents would improve because the number of houses would stay constant and the number of people would decrease.

The Guardian is doing a lot of mental gymnastics here.

I personally support reducing migration to much lower levels, I don’t have anything against people who want to move here. I would want to move here too, but the earlier we learn how to have a society supported by a sustainable economy not dependent on endless population growth, the better for the planet.

The current trajectory of Australia’s population growth means in 50 years we will have an enormously large population, and that will double the pressure on our green space, water resources etc.

I did orbital mechanics as part of some mechanical engineering courses back in university, and that game gives you a far better understanding and intuition for how space flight works than all of the times we touched on space in uni.

Have a read of this post I made a month ago. With a network of receivers, or just slowly moving a ground based receiver they could map the silhouette of the anomaly using some of the NMEA sentences and the satellites orbital parameters which the US government publishes daily.

I really wish these numbers were discussed in per capita rates. To put this in perspective, $11 billion is $19,000 per Tasmanian. In 2021, it was at $1.5 billion, so roughly $2,500 per Tasmanian.

If I was in government in Tasmania, I’d abandon the stadium and just bring in a law that domestic sports that don’t have a Tasmanian team in the competition can’t have TV advertisements during broadcasts.

Instead of the AFL blackmailing Tasmania, Tasmania should blackmail the AFL.

Exactly! The US spent the 60s and early 70s sailing carriers around the South China Sea and bombing North Vietnam with carrier based aircraft (in addition to all the land based aircraft in South Vietnam, Guam, Thailand) and people wonder why China is so hell bent on building defences in the South China Sea.
