  • 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.


  • 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.

    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 know, right? Like, who the fuck needs democracy and sovereignty? If they didn’t want to be part of Russia, then they should have just said so. Has Velinsky tried talking to the justly elected Putin? This 100 billion could be spent on rebuilding all the housing in Ukrane that was blown up by Russia DEFENDING its self from the Ukrainian troops invading Ukraine. This could be 100 billion dollars in food aid spread around the world in the form of Ukrainian grain shipments that have been stalled or sunk, but Ukraine has CHOSEN to stop shipping their grain by blocking their own barges and trucks.this could have been 100 billion dollars in CLEAN oil that Russia could have been exporting to help the world with energy, but instead will have to rebuild because the plants keep blowing up. If only there was a solution that would let the world move on and spend their money on better things. If only we would just give in to Russia and let them take what they want at the expense of others- then the world would be a better place.

    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.


  • 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.

    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.
