  • I am a fan of all good sci-fi, regardless of the time it was made or the limits of the budget. This one is on the list. I will warn others as it has been pointed out- very rape centric plot and story beats. Be sure to watch it with a good level of suspension of disbelief and understanding of the setting. Beyond that, it is one of the best post apocalyptic stories out there and I wish it was redone with more plot, tighter story, and less rape related with the exception of the Topeka plot line. Highly recommend for anyone who enjoys old sci fi or post apoc.



  • 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.



  • Seriously. We are talking about tire tread compared to weight. Both use multiple sizes of tire depending on the year/model. There are a few that overlap in diameter to get the closest to comparison but they still have a very different width. We are talking about a 235/35R18 vs a 235/75R18. That is a huge difference in wall height/aspect ratio and changes how the tire gives under power. Those numbers massively change depending on model as well. Something like an f150 raptor could have a 315/70R17, almost a foot wide. So comparing just the weight and saying they are close enough is far from a fair comparison.




  • 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.


  • You are on a nuke loving platform and people are going to downvote anything that isn’t hard pro nuke. But you are correct. I have had this exact same discussion before. The numbers you are looking for are called the LCOE, or the ‘levelized cost of electricity’ where the lifetime of the technology cost if factored in. Offshore wind is currently the lowest followed by solar. Nuke is clost to 10x the cost. There is even an international nuke consortium that has several reports agreeing with exactly what you are saying and basically sum it up as: if you invested in nuke early, then it is cost efficient to just keep upgrading. If you didn’t invest in it early, then the cost to implement it so high that you are better off going wind/solar. Even if you add in the cost of battery systems, it is still cheaper than building a new nuke plant. And more than that, with these new nuke plants you have to upgrade all your infrastructure because your old wires can’t handle the output loads. If you look at the 30+ billion Georgia spent on this plant, they could have simply given out a micro generation grant to everyone to add solar to their roofs, not needed to upgrade the lines, and been far better off. But hey, just like reddit, if you are commenting on lemmy you better be pro nuke only and ignore the other numbers.




  • No one in real-estate is doubting it being a bubble. The issue is how it will resolve. Not all bubbles burst. The question is if this one is going to simply “cool down” until the market rate catches up (lol, pipedream) or if the propping up will simply plateau it and it will level off for some years for the market rate the then catch up (almost the same thing, still a fucking joke when they try to justify this). Or there is the option of the bubble popping, it then it is the question of how deep the market cut will go, how fast it will rebound, how far up it will rebound, and if it is still worth it to buy now (what some are saying is that it is still worth doing the current fuckery and still profitable even with a bubble burst).

    Let me just point this out- this was the exact same argument by many intellectuals back in the 1950’s about segregation/integration and blacks in science. Why should we care about their color? If they are good scientists with great original ideas and experiments, then surely they will get published and get their positions commensurate to their merit. This is also ignoring their segregated schooling being underfunded, not being welcomed into higher ed unless at specific ‘negro’ universities, and the crippled career paths because of it. But sure, even with their second rate primary education due to their skin color, and their second rate secondary education due to their skin color, and then their crippled career prospects due to their skin color- why don’t we then measure them on merit? The black man never amounted to what out nice ivy league educated white man has done, so why take a risk on them? And again, should we not just judge them on merit? Ignore that if a black man has a novel idea then they must then have the idea reviewed into perpetuity while one of the white reviewers just so happens to come up with the same idea then publishes before the black man.

    So to sit here and still argue that merit alone while disregarding the person is only progress is actually quite regressive.

    Now, beyond that- modern publishing is blind in most every respectable journal because of this issue. It is only after being accepted is the author identity revealed to the reviewers.


  • The pyramids are made of granite. It has a density/weight of approximately 165 lb/cubic ft. As in, a 1x1x1 block weighs about 165 lbs. This block, assuming the standard person in this picture is about 5 ft (people have been getting taller over time) this block is maybe 20 ft cubed. Just an eyeball guess. That would put it at about 1,320,000 lbs.

    The picture has 6 people deep carrying the first stone with what looks like maybe 4 people across? Hard to tell. But going off 6x4 people, that would mean that each person would have to carry 55,000 lbs each.

    Would it be possible? I will let you guess from that. Next question, how many eggs to support it? After some google searches the textbook theoretical best an egg can support is some 300 lbs, but in practice is closer to 120-130 with support/positioning in place (think egg cartons holding them vs just on the ground). This would mean our 1,320,000 lb stone would take between 10,000 to 11,000 eggs to support it.

    How long would it take to get that many eggs??? Good question. Chicken normally lay about an egg a day. So 10,000 chicken take 1 day, or 1 chicken would take about 10,000 days. But what is a realistic amount? Well, let me tell you. In the rabbit hole I found myself in of jokingly replying to this, I found an entire dissertation on “THE EXPLOITATION OF LIVE AVIAN RESOURCES IN PHARAONIC EGYPT: A SOCIO-ECONOMIC STUDY” BY ROZENN F. BAILLEUL-LESUER (JUNE 2016)

    Captivating. Would recommend rabbiting down that hole. And on page 299 we can see that a Pharoah size flock would be about 2,000 Eurasia cranes or geese. So it would take us about a week to put that block in the picture on a bunch of eggs.

    Thank you for coming to my TED talk.

    Evey time I hear about the evil big pharma funding all the studies out there to influence them in they favor, I immediately ask, “where is this funding and how can I get it?”

    Because let’s be honest, unless the leg work is already done, they aren’t funding shit.

    On the flip side of that, I did do a study for 3M and their hearing protection devices (I am an audiology/PhD student) and the funding was great. There were also basically no strings attached other than “use this product, study workplace noise, be able to publish it”.
