    We’d need to find exactly where it “passes over”, which could depend on who you ask.

    No, we don’t. It doesn’t matter when that is, because you and I both agree that it’s out there somewhere, and that at the point in time referenced, a non-chicken laid an egg and a chicken hatched out of it. That’s all we need out of that point, and neither of us are disputing that part of it.

    If you define a chicken as hatching from a chicken egg (“every chicken must have hatched from a chicken egg”), then the egg came first. If you define a chicken egg as an egg that was laid by a chicken (“all chicken eggs must have been laid by chickens”), then the chicken came first.

    Agreed. I, personally, use the broader egg definition you reference in the last paragraph, but a definition of “chicken egg” would put the whole thing to rest, and I propose this: Not every chicken egg contains a viable chicken. We all agree that these eggs are still chicken eggs when we buy them at the supermarket, though, so my proposed definition is that a chicken egg is laid by a chicken. Otherwise, we end up with unclassified eggs in our omelettes, and we can’t have that.


  • In such a case, we would simply need to look backward in history until we find an ancestor that doesn’t meet the chicken criteria. Fowl as a clade were separated from other bird clades before the K-T Extinction Event, and many such species before the event had teeth, which means they weren’t chickens.


  • I see what you’re saying, and I agree with it, but the question isn’t asking “Which egg was the first chicken egg?”, it’s asking “Did the egg come before the chicken?” Determining the exact point is a way of answering the question, but is a lot of work that isn’t strictly necessary to do so.

    We can use the Theorem because we don’t care when that point actually was, the question doesn’t ask that. We just need to prove that there was such a point, and the Theorem does that.

    To use that text as an analogy, we don’t care which is the first purple or blue word, we just know there is one because the gradient starts from red, passes through purple, and ends up blue, so it must have a first purple word and a first blue word.

    chicken would also be able to defined as it’s ancestor

    This isn’t the case, and there’s a mathematical theorem describing this called the Intermediate Value Theorem. Basically, if you have a function describing a line you can draw without picking up your pencil, at some point along that line the value takes on every value on that line. Makes sense, right?

    If I draw a line separating Chicken-birds from Not-chicken-birds, and show the evolutionary path leading from non-chicken to chicken, at some point it crosses that line. We don’t have to know where that point is, we just know it crosses the line at some point.

    At that point, wherever it is, we have a bird that meets the criteria of “chicken” hatching from an egg laid by a bird that doesn’t.

    Besides, this is all pretty moot. We actually know when and where chickens originated. They originated about 3000 years ago in China and India after being domesticated from Southeast Asian Red Junglefowl.






  • For SSD’s, it’s 100% a logical table, because data is stored all over the place for load balancing purposes, so it already uses a logical table to keep track of what each block is for at any given point in time.

    For HDD’s, historically they were physically separated, and they mostly are still, but there’s still a logical table, and there’s no reason the logical table can’t say “Blocks 0 through 1234 and 2000 are part of partition 1” if you have something somewhere else that you want on that partition.

    Man in Black : All right. Where is the poison? The battle of wits has begun. It ends when you decide and we both drink, and find out who is right… and who is dead.

    Vizzini : But it’s so simple. All I have to do is divine from what I know of you: are you the sort of man who would put the poison into his own goblet or his enemy’s? Now, a clever man would put the poison into his own goblet, because he would know that only a great fool would reach for what he was given. I am not a great fool, so I can clearly not choose the wine in front of you. But you must have known I was not a great fool, you would have counted on it, so I can clearly not choose the wine in front of me.

    Man in Black : You’ve made your decision then?

    Vizzini : Not remotely. Because iocane comes from Australia, as everyone knows, and Australia is entirely peopled with criminals, and criminals are used to having people not trust them, as you are not trusted by me, so I can clearly not choose the wine in front of you.

    Man in Black : Truly, you have a dizzying intellect.

    Vizzini : Wait till I get going! Now, where was I?

    Man in Black : Australia.

    Vizzini : Yes, Australia. And you must have suspected I would have known the powder’s origin, so I can clearly not choose the wine in front of me.

    Man in Black : You’re just stalling now.

    Vizzini : You’d like to think that, wouldn’t you? You’ve beaten my giant, which means you’re exceptionally strong, so you could’ve put the poison in your own goblet, trusting on your strength to save you, so I can clearly not choose the wine in front of you. But, you’ve also bested my Spaniard, which means you must have studied, and in studying you must have learned that man is mortal, so you would have put the poison as far from yourself as possible, so I can clearly not choose the wine in front of me.

    Man in Black : You’re trying to trick me into giving away something. It won’t work.

    Vizzini : IT HAS WORKED! YOU’VE GIVEN EVERYTHING AWAY! I KNOW WHERE THE POISON IS!

    Man in Black : Then make your choice.

    Vizzini : I will, and I choose… what in the world can that be?

    [Vizzini gestures up and away from the table. The Man in Black looks backwards. Vizzini swaps the goblets]

    Man in Black : What? Where? I don’t see anything.

    Vizzini : Well, I- I could have sworn I saw something. But no matter.

    [Vizzini tries to hold back laughter]

    Man in Black : What’s so funny?

    Vizzini : I’ll tell you in a minute. First, let’s drink. Me from my glass, and you from yours.

    [Vizzini and the Man in Black drink]

    Man in Black : You guessed wrong.

    Vizzini : You only think I guessed wrong! That’s what’s so funny! I switched glasses when your back was turned! Ha ha! You fool! You fell victim to one of the classic blunders - the most famous of which is “never get involved in a land war in Asia” - but only slightly less well-known is this: “Never go in against a Sicilian when death is on the line”! Ha ha ha ha ha ha ha! Ha ha ha ha ha ha ha! Ha ha ha…

    This is a terrible position to take. Anyone can be educated.

    The thing is, nobody likes being flat-out told they’re wrong, and with the way arguments on the internet go, that’s all that will ever happen.

    Most of my friends are heavily conservative, but I’ve learned how to have productive conversations with them about issues, and it’s almost always “This is how it benefits you if it were different.”

    It’s difficult sometimes, but it’s worth doing, and it’s important to understand that the guy you’re talking to isn’t the enemy. He’s just another dude.


  • Says who?

    Says the diagram in the OP, the EM spectrum of a 5800K star, which clearly shows a peak within the visible spectrum in the blue band, and a significant (25% or so) drop off by the time it gets to the red band. Those aren’t relatively equal.

    As near as I can tell, your entire argument is based on what a human being perceives to be “white”, and I’m not talking about perception at all, because it lies. Examples:

    • The sky looks blue. It’s not blue, and you can tell by looking anywhere that isn’t the sky in the daytime, because the air is the same everywhere.

    • Related: the sun looks yellow. The sun looks yellow for the same reason the sky looks blue.

    • When I close my eyes, I can’t see anything. That doesn’t mean everything is black or the same color as my eyelids.

    • Your own dress example, where different people would see different colors in the same dress.

    You and I are arguing about two completely different things. You are talking about what color something looks to be, in terms of colloquial terms used to describe things people can see. I am talking about what color it is, in terms of temperature and wavelength, which are things people can measure.


  • Colors are a perception, true, which is why we don’t really talk about colors, we talk about wavelengths and temperature. 5800K is not white (relatively equal amounts of all visible light wavelengths), it’s light blue (decent amounts of most visible light wavelengths, but a significant peak in the 450-500nm wavelength band, which looks blue to us). Lightbulbs use color temperature because filament and halogen lights generate light the same way the sun does: by getting hot, and how hot it is determines the light wavelengths emitted. That’s why I included the chart, it’s a good analogue.

    If you look at the graph provided in the OP, you can see for yourself that there’s significantly more blue than anything else being emitted.


  • It’s really a pale blue. If it were white, the visible spectrum would be pretty even, but you can see the graph is higher on the blue edge and lower on the red edge. There’s enough green and red to brighten it a lot, but it’s definitely blue.

    In fact, the sun’s surface temperature is around 5800K, and you can look up what color that actually is wherever you go light bulb shopping.

    This shows the colors based on temperature, and the sun is firmly in the “Day White.” It’s called white, but you can see it’s pretty clearly blue, especially next to the “Direct Sun” color.
