        I took an environmental science class in college, and the professor was a former president of Shell. As part of the curriculum, we had to read his book, Why we Hate the Oil Companies. Predictably, it’s a corporate non-apologia, which—hilariously—completely avoids engaging with why we actually hate the oil companies.

        Not the original commenter, but I briefly had one professor in college that did that (their book was $50, though). It was an elective course for me, fortunately. I was able to switch for a different class that fit the same requirement without being forced to buy a book the professor wrote.

        Can you really understand zero? I mean, I get what it represents, but I still sometimes struggle to understand its usage…like, you can’t divide with zero thats for sure, but did you know you can divide a number with a really small number (like an infinitely small number) and you get a really large number (like infinitely large)? So, in that special space, if you suddenly replace “0” with a “number-so-close-to-zero-it-can-smell-it” feel free to divide and conquer, and get infinity.

        Oh, and sometimes, if you feel like math is letting you down, remember, you can always use positive and negative zeroes, so your math-thing can now work!

          I don’t understand why you can’t divide by zero.

          If you turn it into a word problem 10/1 could be stated as “If you have 10 things and put them in a bucket, how many things do you have in the bucket?”

          10/2 becomes “If you have 10 things, and and put an equal amount of them in two different buckets, how many things are in each bucket?”

          So, wouldn’t 10/0 become “If you have 10 things, and don’t put any of them into the bucket, how many things are in the bucket?”

          I’m bad at math, go easy on me.

            The fact that there’s no buckets means that you can’t then usefully draw any further conclusions about the ratio of buckets to things. In your first two examples we can take the results and use them to work out further things like how much might the buckets weigh, what happens if we add more buckets or more things, etc.

            In the divide by zero answer, we know nothing about the buckets, and the number of things becomes meaningless. But worse of all is that it’s easy to hide this from the unwary, which is why you occasionally see “proofs” online that 1=2, which rely on hiding divide-by-zero operations behind some sneaky algebra.

            When we say we “can’t” divide by zero, we mean ok you can divide by zero, but you’ll get a useless answer that leaves you at a mathematical dead end. Infinity isn’t reversible, or even strictly equal to itself.

              I think I get it, thanks for taking the time to explain.

              With 10/2 there are two buckets, and 10/1 there is 1, so with 10/0 I was wrong to phrase it as there is a ‘bucket with nothing in it’, it should be ‘there is no bucket, so you can’t divide the things, even if you wanted to.’ Right?

      That wouldn’t be true for Christianity as 3 of the 4 Gospels were cribbing off the 4th one. Heck the Gospel of John and the Revelation unto John were written by at least two different people and the Revelation likely was included at the Council of Nicea because they both had John in the name. Christianity would be very different without revelations.

        The prevailing consensus is that the gospels of Matthew and Luke were cribbing from the gospel of Mark and a text that is lost to us that is referred to as Q. The gospel of John is original as far as we know.

        Also, a lot of the Pauline epistles weren’t even written by Paul.

                  i really feel like your input has been the truly rude part of this conversation.

                  My input has been the simple fact that people who insist on making every conversation about religion are fucking exhausting to everyone else.

                  I have not subbed to any religious or anti-religious communities, and yet people seem to think it needs to be a part of every discussion. You’d think out of all people atheists wouldn’t be the ones doing that shit yet here we are. If you want to talk about that shit go those communities and you will find plenty of like minded people.
