    Uh~~~before me dino could finish reading that meme with the upside-down airplane~~I was already thinking about a dead cockroach.
    But, yeah, I've had pets that would trustingly show me their upturned bellies.
    Don't want another pet. They can big time let you down by dying.

      Dino, I know what you mean by not wanting another pet. It hurts so much when they die. We had our cat for fifteen years before she died. She was a member of the family. But we enjoyed her for all the time that she was with us. I had a dog as a kid. I think of him often.
      Hope that everyone had a great Thanksgiving.

    Yep, gave Flintstones to the kids! I've successfully completed the "balance the ice tray" maneuver a bazillion times, but a few times the floor (or my socks) got rinsed. Love the Sponge Bob analogy, LOL!

    Thanks for another great start to my day.

      For those flummoxxed by higher mathematics, it's important to remember that a bazillion (along with its friend the squillion) is an imaginary number. Sort of like π, a round number. Don't tell me π are square! But as we all once learned, e to the iπ minus one equals zero, unless the oiler is broken.

        Very funny, that pun on Euler! Seriously.

        I thought it was e to the (minus ipi). Equal one.

          Oops. I got singed by the sign (not the sine). It's actually e to the iπ PLUS one equals zero,

            e^(pii) = cos(pii) +sin(pi*i) = -1 + 0 = -1

              Sorry, Firefox mangled the syntax. Once again,
              e^(pii) = cos(pii) +sin(pi*i) = -1 + 0 = -1

                Any idea why (pi*i) changes to (pii) ?

                  I wish I could help, but I'm still flummoxed at what keyboard trick Snezzy used to get the symbol for pi to show up in the text. I'm sure it's a PEBKAC. (Problem Exists Between Keyboard And Chair)

                    I went to some website, probably Excitlopeedonya or something that had a π, and copied it. That'll be CTRL-C. Then I pasted it (CTRL-V) where I wanted it. π π π π π π π π π . Easy as π

                    There are various other ways to do it, some worse than others. For those who like emacs, there is this approach: https://stackoverflow.com/questions/1...

                    Here's some more:

                    For more about oiling, no that should be Euling, there is this:

                      Thank you, Snezzy! The links are fascinating and helpful. This is one reason I love the Gulch! The knowledge on so many topics keeps on flowing from so many folks like yourself!

                      Keyboard table showing the various codes for obtaining pi, but I had to check and found 003C0 (hex) is 960 (dec).

                      I'll have to bake the last one the next time I make pi, LOL.

                      I'll check out your links, but I wanted to try to put into words, at the request of my good friend and mathematician, Roger, why my previous post was incorrect. I believe, and so does Roger, that I am calculating subconsciously, and the mental apparatus I am using is related to another talent I have that I have tried to keep hidden all my life. In other words, what I am doing, how I am calculating I can not yet express algebraically. But the 'method' is related to how logs use differences in calculations, rather than ratios or proportions. Roger thinks I've been doing this since childhood, and it's why I was able to integrate faster than the first integrating calculators. And he wants to know what I am doing!!

                      I hesitated to write this, but maybe putting it into words will help me "access" this seemingly---to me---arcane information!

                      I might add more to this later, if you don't mind.

                      I will check out your links.

                    My post was wrong anyway. It should have been:

                    e^(π i) = cos(π) + i sin(π ) = -1 + 0 =-1

                      My current math skills are corroded with age and disuse so I never would have caught it, but I appreciate you getting back to the Gulch.

                      Interestingly, a few days ago I acquired a used two-volume set of Math books totaling over 2400 pages long and covers from simple math all the way to calculus. My hope was to brush through it over the next year or so and sharpen my knowledge a bit just for the fun of it. The highest I ever went in formal math education was to ace a precalc college course around 1982 (electronics courses got me into Maxwell and a bit more, but I can't recall most of it now). I'm now 72 and am still interested enough to give it a go. So, here in the Gulch, Snezzy and you are giving me the spark to get on with it.

                        I will be 85 soon and have forgotten most of the math to the masters level. I have had heavy duty social anxiety all my life so couldn't practice math or my chemistry degree stuff. Went into lawn care business with 4 months off in winter to use math as a hobby. I like this:

                        https://www.youtube.com/watch?v=2pTfC...

                        Never did that stuff in algebra class in 1961.

                        As for books, no one wants my library of 1500 books with several hundred math and lots of physics and computer books. Young people are not interested due to getting everything online.

                          I started to watch the video (nice), but breakfast is calling so I'll finish it later. Don't know why someone would down vote your post, but I bumped it back up.

                          I had to drop college for family/financial reasons and never went back. I was running a 4.0 in Digital Electronics and the institution gave me a "Field of Study" diploma with distinction, but I never completed the degree. I, too, have accumulated a good sized library that will likely be recycled or land filled upon my leaving the planet.

                            I wanted electrical engineering but it had a speech course so went for chemistry course but had senior seminar which worried me for 4 years. I had a panic attack before my presentation of use of LASERs in chemistry. Social anxiety isn't easy to live with though nice not dealing with others and being alone during COVID19 lock down.

                            OK, I finally watched the whole video and had to back it up and pause in a few spots, but got lost towards the end anyway. I've never been introduced to the Lambert W function (at least I don't recall it). It's a proof I have a lot of work to do if I want to go "there", LOL. If a numerical solution was required, I figure with a scientific calculator I could have brute forced a very close answer in far less time than it took the professor to explain it.

                              Sorry I should not have given that one. The w function is something I had not encountered before.
                              Look on youtube there are dozens of other ones, some hard but fun if you like puzzling things.

                              That's odd, no one down voted that time.

            I'm working on it. I always have difficulty remembering how Euler thought of it. Geometry is my math forte, and I believe there is a geometrical relationship here, if you consider that i, the imaginary number, is used as a mathematical expression for a change in direction. And I think there is a relationship between the exponential function and the form (in Pythagorean terms) of the circumference of the circle.

            I was thinking this morning, if e to the pi is calculated, it would be about e to the 30 something, and call that k, then you could say that given circle A, with circumference CsubA and diameter DsubA, then e to the pi would equal k and e to CsubA would equal k*e to the DsubA. It needs work, but it will give me a platform to the more directional equation of e to the minus pi(i). Well, anyway...

            I see it geometrically as a relationship between growth in circumference, diameter, and the exponentiation of it. Something like that. Still only a mote in my eye.

              I think this is wrong.

              The correct equation of e to the pi, is e to the CsubA over DsubA, so that e to the 1 over DsubA raised to the CsubA equals k. I think this is right: take e to the inverse of the diameter and raise it to the length of the circumference, and that would equal 23.14092 (not 30 something).

              Now you've got me interested. But I've got to help America through her current 'reality intervention' so it may be awhile.

                You are correct placing definition of pi instead of the symbol pi. Must be a geometer. That way would make math a bit harder. The symbol

                  the symbol standing for the specific value 3.14159... is easier than measuring a circle. It is not possible to physically use pi exactly being an abstract mental irrational object. All math is abstraction, a small part of it dealing with the real world.

                    If you want to continue with this, let me advise you that your thinking is like that of two black professors of physics I have talked to and is what is responsible for the backwardness and primitivity of the black Sub-Saharan race. It wasn't European oppression that kept them backwards, it was their own lack of ability to find innovation and change in the perception and representation of reality. It's in the genes.

                    Now I will not talk to you again.
