    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.

    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”.

    I have learned that stats for research is a dark box that you put numbers into, shake it up, and then record the numbers that come out. I use SPSS, my advisor uses SigmaPlot, and another PhD student in my lab uses R. Sometimes I’m not even sure if we are getting the same numbers out of the shaken black box and I am too afraid to ask…

    ANOVA? Sure, it is those clicks in that menu. ANCOVA? MANOVA? sure, there is some thing I check off or some other spot I click on. What do they do? The computer prays to the number gods with a different accent, then I shake the ritual box and read the numbers that come out.


  • I agree with you as a realist on the situation. We will never stop manufacturing them, at least for the foreseeable future. But we forget that something like recycling is the last stage of the 3R’s to follow. We must first look to reduce consumption. We need to find alternatives where possible, and switch away from these forever chemicals anywhere we can. Next, while “reusing” is not the best term here, but we need to find ways to extend the life of the products that we are forced to use and try to use them up in every way we can. Then lastly we need to be recycling it as best as possible before we send it to an incinerator, or more realistically a developing nation landfill.

    Reduce -> Reuse -> Recycle is listed that way for a reason. Everyone always just jumps to the final stage then argue about how bad the recycling is while not even considering ways to reduce or reuse throughout the entire process.


  • 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).”



  • 600$

    To employ someone at 10$/hr, their actual cost is probably close to 15$/hr when you factor I them coming in to work in the office and all the costs associated with that. At 15$/hr it takes 40 hrs to cost 600$ to thr company. That is one week of work for one employee. This means that they could have a 600$ fuck up every week and still break even over hiring a person. And we are talking about just one person. Chat support is nor.ally contracted out as entire teams and departments.
