  • Congenital? No. Acquired? Yes. The area of the brain that processes and interprets sound has to develop. Without sound input as a child, that won’t happen.

    Current leading theory of tinnitus is called the ‘central gain’ theory. This is where the brain becomes accustomed to seeing signals from the ear at a certain level, and when that neural level is no longer at that level it will add in its own noise to make up the difference. This noise is then perceived as a tone or sometimes a broadband sound, commonly described as either a ringing or a whooshing sound. Sometimes it can also be described as crickets. Depends on the person and cause. Not all hearing loss comes with tinnitus, but most tinnitus comes with hearing loss. In audiology school we had a whole class on tinnitus and covered many interesting aspects exactly like your shower thought here and went over papers on every angle you could think of. It was fun. But in the end, the brain has to at a minimum know what sound is to even perceive sound.


  • While any aircraft sent to ukrane is nice, I sure hope they aren’t paying much for them. That airframe is about 60 years old with the last major design overhaul in 1990 and its last electronics upgrade in 2000. They would be better off buying F15e’s or even the new f15ex. He’ll, even getting some last Gen f16’s or f18’s over there would be as good or better, but cost probably more. The f15 though is probably the best multiroll jet for the cost.

    Now, if we are talking about sending some OG Mirage 2000 fighters over there, then that sounds like the ultimate white elephant gift France could give. The US could sent some F4 phantoms over while we are at it.

    The big news I the training of 4500 pilots. That is huge. If they could do that, then the mirage 2000 could basically turn into their base fighter trainer and use it as the training wheels to get the new pilots experience and into bigger and better things.




  • It isn’t just about the pumping. You can pump crude all day and still be broke. Look at several of the middle east smaller countries or even most south America pumpers. The refining is where the industry and money is really at. Cars don’t burn crude oil, it has to get refined. Plastics don’t come out of the ground, they have to get refined. Saudi Arabia is the world’s largest crude oil exporter and they still have to rely on others to refine.

    In fact, here is a direct quote from OEC-

    “In 2021, Saudi Arabia imported $7.43B in Refined Petroleum, becoming the 27th largest importer of Refined Petroleum in the world. At the same year, Refined Petroleum was the 2nd most imported product in Saudi Arabia. Saudi Arabia imports Refined Petroleum primarily from: India ($2.17B), Greece ($1.09B), Russia ($892M), United Arab Emirates ($835M), and Egypt ($689M).”




  • Ethiopia DID have a coast. It was what is now known as the country of Eritrea. They were forced to be part of the country after WW2 in 1950, and ignored the wishes of the people to remain independent. Then by 1961 a war for independence started and lasted for 30 years. It ended with the Eritrean forces taking the Ethiopian capital and winning the war capture the flag style, but with guns.

    As far as Djibouti, they are probably the best example of American modern imperialism. The country enjoys a stable currency by using an American backed currency. In exchange the US has their Horn of Africa base there. Because the country is so small but the base has so many troops and the US pays to lease the land, the US military ends up making up a little bit over 10% of their entire GDP. This is the base that launches the anti-pirate operations for the region, not only providing security for Djibouti, but security for the entire HoA. Say what you want about the USA and their modern imperialism, but the only thing anyone in that region agrees with is that they love the US troops there and the mission they do.

    If Ethiopia wanted to take Djibouti, not only would that piss off literally every other country in the region, they would also have to go through the USA to take it. Good luck with that.



  • In 2000 the Afghani was worth 75,000 to 1 USD. During ISAF occupation it was fixed at 50 to 1. It is now at 70 to 1 and dropping. Let’s stick to one argument at a time rather than playing the whataboutism game. You said the USA destroyed their economy, yet the evidence strongly says otherwise. Before 2001, Afghanistan was the second poorest country in the world. When ISAF pulled out it was ranked at about 40 (I say ‘about’ because it was still growing and changing faster and the rankings were uptated). In the short time of Taliban rule they have dropped back down to sub 33 with exact number still to be determined. (The sub 33 ranking is important because there are only 33 countries on the UN “least developed countries” list).

    I would spend time debating topics like this with educated people and those that are open minded, but you do not seem like you fit either group. Do not expect a reply.





  • MrEff@lemmy.worldtoTechnology@lemmy.mlPrice of solar dropped 89% in ten years

    I can see that critical thinking isn’t your strong suit, but I’m willing to comment it out with you instead of just down voting.

    If the price of solar is already the lowest -and still dropping- then how is the most expensive option that takes about a decade to implement a better option for right now? This apparent point of diminishing returns is only beginning to manifest in even lower prices than this 2019 chart. And this diminishing returns point is only in the cost of the panels dropping; they are still getting better in technology and improving efficiency while maintaining low prices. If your argument is “solar can’t continue on this trend forever” -no one expects anything to consistently drop almost 90% every decade. Of course it will level out. And when it does, it will STILL be the cheapest option.


  • Huge up front costs.

    https://world-nuclear.org/information-library/economic-aspects/economics-of-nuclear-power.aspx

    “On a levelized (i.e. lifetime) basis, nuclear power is an economic source of electricity generation, combining the advantages of security, reliability and very low greenhouse gas emissions. Existing plants function well with a high degree of predictability. The operating cost of these plants is lower than almost all fossil fuel competitors, with a very low risk of operating cost inflation. Plants are now expected to operate for 60 years and even longer in the future…”

    “World Nuclear Association published Nuclear Power Economics and Project Structuring in early 2017. The report notes that the economics of new nuclear plants are heavily influenced by their capital cost, which accounts for at least 60% of their LCOE. Interest charges and the construction period are important variables for determining the overall cost of capital. The escalation of nuclear capital costs in some countries, more apparent than real given the paucity of new reactor construction in OECD countries and the introduction of new designs, has peaked in the opinion of the International Energy Agency (IEA). In countries where continuous development programmes have been maintained, capital costs have been contained and, in the case of South Korea, even reduced. Over the last 15 years global median construction periods have fallen. Once a nuclear plant has been constructed, the production cost of electricity is low and predictably stable.”

    TLDR: If you weren’t already on the nuke train when it was going, the upfront costs are too much to make it worth it this late in the game. You are better off just getting solar/wind + battery. If you already invested in nuke, then you are good to keep updating them.



  • Death toll as of yesterday was reported around 8,000. The US/coalition 20-year war in Afghanistan was (rounding UP) 50,000. That puts it at an average of 2,500 civilian deaths per year. Even THAT number was high enough for people to call for war crimes investigations. Now Israel has reached over 3x the yearly average in only 3 weeks. On track to pass 10,000 by the one month mark, too. I’m not saying that Isreal doesn’t have the right to defend its self, or even defense through offense, but there is a point that we need to agree is too far; and I think we are a bit past it.
