Questions
Where does the word "beeline" come from? (00:36)
Our guess
A honeybee flying the most direct path back to the hive; one host suspected geometry (a bisecting line) or navigation.
A honeybee flying the most direct path back to the hive; one host suspected geometry (a bisecting line) or navigation.
Reveal the answer
The answer
From the straight line a honeybee takes when returning to its hive. It appears in early 19th-century print (one example from 1808), and "bee lining" was used to locate wild bee colonies by trigonometry.

[00:00] All right, I heard we have an undegoogable coming out of DC this week, is that right? [00:11] Oh, we doing undegoogables? That was the play of super excited. [00:16] Told us we had to. So we said we signed up for it. [00:23] In the end, it's going to be better and more true than Google can give you. [00:28] Yeah, I was surprised we hadn't done this one yet. And maybe we have and we'll discover it as we [00:36] work our way through this undegoogable. But so Jill, the other day we were out and we were going [00:42] to get back and she said, you know, when we get home, I'm making a beeline for the bathroom. [00:51] Beeline, what is it? What is a beeline? Where does that phrase come from? What's going on? [00:58] I assume it's about honeybees. Okay. They just do bees make lines? [01:09] The most direct route from flower to flower. I think that's the beeline. [01:15] Okay. How sure are you about that? And how many bees have you watched fly? [01:23] That's sort of my thing, right, Joey? It's like, [01:26] uh, these are notorious, like they do dances and all kinds of crazy stuff to give directions, like [01:33] super famous for picking the most direct route for me to be. [01:36] Right. Because that was our theory as well, is it's the bees come back to the hive. They're like, [01:44] look, man, I know where there is great nectar. Let's go get it. And then they go straight to [01:51] it or something like that. But yeah, I agree. I don't know that they actually make a, I don't [01:57] know how good they are at homing. I know they swarm me in like circles and circles and circles. [02:03] And like, you can walk like a half a block away and they're still following you. So that doesn't [02:07] seem like they're that focused. You don't think that's where the phrase comes from, do you? [02:14] What? From, from swarming you? Yeah. Short for beeline to Coalson. [02:18] Yeah. It probably goes back further than, than, uh, you know, me. Yeah. [02:26] I mean, everything is about me and everything does surround me, but maybe not this race. [02:33] Can we think of any alternative? Uh, yeah, no, I feel like I know this. I feel like it's a [02:38] geometry thing, right? It's the, it's a geology thing. No geometry thing. So geometry. So it's [02:45] like a B and C and a triangle or whatever. And then there's, and I don't even, I don't [02:51] know which one it is, but like, I feel like on a, if you have a compass or whatever, like you, [02:55] there's an A and a C and then you find the B line through some math thing. And it's always [03:00] a straight line through the middle of the, um, uh, triangle, like the different geometry [03:08] class. The B line splits the triangle and exactly half [03:21] or something like a bisection. Yeah. It's a bisection thing. Yeah. So, okay. So, so like [03:26] you're navigating and you're like, okay, there's a mountain over there and there's a mountain over [03:30] there. And then I, and then I have my compass go through the B that's my B line. [03:34] So I'm, I'm fairly sure that B line is spelled B E E L I N E. It's not like B dash line. Okay. [03:43] So that was going to be another question. Cause I don't know that I've seen it written. You [03:48] don't think it's like hyphenated. Yeah. Well, okay. Well, what if it's, are you sure it's [03:52] that way? Cause like, what if it's like the, like some New York thing where like the, the [03:57] B line bus is like the fastest, it's the most direct route from midtown to [04:03] downtown or something. Yeah, it's not. [04:07] That's the A train. I'm saying it's, it's a, it's a compass geometry thing. [04:16] What are the pro track, that's what I'm looking for. [04:19] Based on spelling, you're pretty confident that it's a B, a honey bee situation. I do. I actually [04:26] think it may be that even though bees like spend a lot of time flying around doing [04:30] weird dances, once they've done so, then they would at that point navigate together [04:36] from a point eight to a point B on something approximating a straight line. [04:42] Yeah. Yeah. I think going home, there's no, you know, no stopping, no, no detours. Once [04:48] you've got your, you know, pollen on your legs, you've got one job and it's to get home. [04:54] I mean, I don't waste any time at that point. I don't stop at the bar. [04:57] No, you got to get home and work yourself to death like now. [05:01] Yeah. You got to get home and barf up that nectar. [05:10] Okay. And when do we think this, uh, terminology came into parlance? [05:17] Like this is an American thing and the from farmers in the [05:21] beekeepers 50, the forties or something. [05:24] How long have has like bee keeping been a thing? [05:30] I think that's like, I think ancient Egypt. Yeah. [05:33] Like at least. [05:34] Yeah. I was kind of thinking Egyptians as well. [05:39] I'm going to go. [05:40] But I don't know if they came up with a term. [05:42] I'm going to go with the Greeks. It was the beta line. [05:49] I'm going to go, um, uh, 1600s, uh, sailing. [05:55] Okay. [05:56] Going to your maritime. [05:57] Maritime. It's a protractor. It's a compass. Yeah. [06:00] Yeah. Yeah. Yeah. [06:02] Oh, I learned an interesting thing. Speaking of maritime. Uh, so, uh, the sauce, [06:08] the red sauce, you know, that you put on noodles, uh, was, uh, originally developed at sea. [06:15] It was what the, the sailors used and that's why it's called marinara. [06:20] Because it was, uh, I had never put that together. [06:24] No, that's cool. [06:25] Nah, I assumed it was some Italian stuff. [06:29] I mean, it is, but yeah. [06:31] It's the Italian marinara. [06:33] That's kind of cognate for maritime or something. [06:37] Close shared. [06:37] Well, but the marine, the brute, the marine. Yeah. [06:41] I think we put that together. Okay. [06:44] Okay. [06:44] Well, we got that one. We nailed marinara. [06:48] I'm seeing spelling as both ways hyphenated and unhyphenated. [07:00] Uh, are you saying B dash or B E? [07:04] Oh, no. B E. Okay. [07:10] I'm seeing early 19th century with reference to the straight line supposedly taken [07:15] distinctively by a B when returning to the hive. [07:21] I'm also, so the B lining is, uh, the ancient aren't used to locate feral B colonies. [07:29] This is performed by capturing and marking of foraging worker bees and releasing them [07:35] from various points to establish, oh my God, by trigonometry, [07:40] the direction and distance of the colonies home. [07:48] So maybe trigonometry instead of geometry. [07:50] Damn it. I was so close. [07:55] The earliest, uh, of the phrase is from the Davenport daily leader, January 1808. [08:05] Gustav single, single senior of rock Island was thrown from his sleigh on third avenue [08:11] in that city yesterday afternoon. [08:14] The horse became frightened and turned abruptly, ripping the cutter. [08:18] The horse made a B line for home. [08:23] Is that 1808? Was that right? [08:25] 1808. [08:27] Although it was probably, it looks like in common usage already. [08:32] Probably. [08:37] There was also a B line railroad in Indiana. [08:41] Was it the fastest way to get downtown? [08:48] Bees don't actually make the most direct path back to their, um, high, [08:56] but it came, uh, the phrase came around before science figured out how bees work essentially. [09:05] No, I mean, I think it is that they go directly back. [09:08] Okay. [09:09] I'm just reading something else. [09:11] Yeah. [09:11] Although I don't, I don't know a whole lot about B navigation techniques, [09:17] but there may be like way points or something, right? [09:19] Like it would be otherwise straight, but for pre-existing way points that they use to navigate. [09:24] Right. [09:25] Yeah, but I think, yeah, I think, yeah. [09:29] And then you can use that as a tool if you're, uh, trying to, uh, you can, [09:38] you can use that as a, uh, uh, I'm trying to find another word. [09:42] It's not working. [09:43] Got y'all locked in. [09:48] But you can use their behavior against them. [09:51] If you are, uh, uh, be lining, uh, you just use, just add their behavior plus a little [09:58] elementary to trigonometry and Booyah, you got yourself some honey bees. [10:09] I don't really feel like a poo bear was good at trigonometry. [10:16] You think it was Eeyore was the math guy. [10:21] Maybe piglet. [10:24] What was piglet's deal? [10:26] He was incredibly afraid of everything, but also incredibly loyal to poo. [10:31] So like he'd get talked into doing stuff he didn't want to do because he loved poo so much. [10:35] That was his thing. [10:37] That was his character arc. [10:39] Right. [10:41] And then occasionally he'd get to do something courageous, [10:43] which would help his, his fear stuff. [10:46] To use it's like self-esteem issues. [10:48] Yeah, yeah, yeah. [10:49] Okay. [10:51] I'm glad I got over that. [10:56] Should we, should we break down psychologically all of the way to the poo characters? [11:01] I mean, not today, but that's a different show for sure. [11:05] But, uh, this is going to get deep.
