Introduction
You're listening to the Skeptics' Guide to the Universe, your escape to reality.
S: Hello and welcome to the Skeptics' Guide to the Universe. Today is Tuesday, April 24, 2013, and this is your host, Steven Novella. Joining me this week are Bob Novella,
B: Hey, everybody.
S: Rebecca Watson,
R: Hello, everyone.
S: Jay Novella,
J: Hey, guys.
S: and Evan Bernstein.
E: Mach-cho maroon.
S: Thank you, Evan.
J: That sounds very Game of Thrones-y.
E: It's the first words I think I've ever spoken in Dothraki.
J: And what does it mean?
R: It means "Die, scum!" (laughter) (garbled comments)
S: It means: "Your horse is ugly."
J: Does it mean Hello?
R: It means hello.
E: Yes. It's the long way of saying "hello."
S: Or as close as you get to it in Dothraki.
J: Game of Thrones is kicking ass. The latest episode was awesome.
B: Yeah.
J: And that has nothing to do with science.
E: Everything to do with pop culture.
S: That's right.
This Day in Skepticism (1:02)
April 27, 1791: Birth of Samuel Morse
R: But you know what does have to do, slightly, with science is that today, April 27, is the birthday of Samuel Morse, who was born in 1791.
E: Oh, happy birthday.
B: Wait. I missed that segue. What's, how did you do that? Oh, never mind. Go ahead. (laughter)
R: You know, it was just so smooth, you missed it. Yeah, so, Samuel Morse, most people know as the inventor, or co-inventor, of Morse code. I found it really interesting, I was reading up on him, and apparently he got interested in telegraph systems because he was far away from his wife when she took ill, and he got a telegram saying that she was basically on her death bed. And by the time he was able to rush to see her, she was already dead and buried. And he was so angry about it
E: Sad.
R: that he gave up painting. He had been a painter. And he dedicated his life to finding a better way to communicate over long distances. So, yeah, a tragedy, but it was positive results for humanity.
J: You know what he said when he got there and they said "Your wife is dead."? He said, "She's dit dit dit dit dit dit dit dit dit dit dit dead?"
B: Oh, my, God. (groans and laughter)
S: That was bad.
E: Wow.
J: Guys, guys, come on.
B: Please edit that out, Steve. (laughter continues) Imagine how awesome that was back then when you realize that, holy crap, we can communicate so fast over hundreds, thousands, of miles. It must have been like pure science fiction to them.
S: Yeah, so, I learned some interesting things about Samuel Morse. First of all, he graduated from Yale. So he's a Yale alum. Supported himself as a painter, as Rebecca said. He didn't just invent, actually co-invent, with Alfred Vail, Morse code. He actually developed the electrical telegraph. And he, one of the critical inventions for that was the relay. He invented the relay. You guys know how that works?
J: Sure.
S: Hit me.
J: Oh, the re--, you mean the thing that boosts the signal so it can go over long distances.
S: Yeah. So, 'cause the wires back then were so crappy, one signal could really only go not even a mile. It couldn't go very far at all. So he figured out a way of putting in a relay where the signal hits a relay circuit which essentially, a very weak signal, you have a very sensitive circuit, so that even a weak signal comes in, and it activates a magnet, which triggers an arm, which creates a new click, which then can go the next distance to the next relay. So very simple, very basic, but that was a critical invention to the functioning of the
B: Oh, yeah.
S: over long distances.
B: They had to set those up every mile? Wow, that's a lot.
S: Yeah, something like that, yeah.
B: Initially, at least.
E: It's like fiber optic today; they have relay stations.
S: Do you guys know what the first message sent across one of those telegraphs was?
J: Yes.
B: I used to know it.
J: "Send more Chuck Berry."
R: Well, I only know because I read it like an hour ago.
J: Say it with authority.
R: I know exactly what it was, Steve. It was "A patient waiter is no loser."
S: Right. Which is interesting because it's not . . .
B: That's kinda lame.
S: Yeah. It's kinda lame.
R: Yeah.
S: But his father was
R: It's no "What hath God wrought?"
S: Yeah, "what hath God wrought?"
E: Or "Watson, come here, I want you.
S: That's what he said when he was transmitting from the Supreme Court chamber.
E: Right.
S: His father was a Calvinist preacher, so it's kind of, I guess, has the moralistic tone with which he was raised. His father was Jedidiah Morse. You gotta love that name, Jedidiah. Not many Jedidiahs around today.
B: No.
S: And Morse also was pro-slavery. And was active in resisting both Catholics and immigrants.
E: Um hm.
J: When you say "resisting," what do you mean "resist"?
S: He was, he actively campaigned against immigrants and Catholics.
R: Horrible person
J: Wow.
R: who did some good stuff.
J: I didn't know that.
B: I like him a little less now.
S: He was a product of his time and his father.
B: True.
S: Gotta cut him a little bit of slack.
R: I don't know, there were plenty of people of his time who were vehemently anti-slavery.
S: Um hm. I agree, I just said "a little bit." It's hard to look back 200 years and be too heavily moralizing.
R: Eh. I find it easy. (laughter)
S: Are you guys enjoying the first real days of spring that we've had so far?
J: Awesome.
B: Oh, I'm lovin' it. 'Bout time.
E: Yeah, this 42 degree weather is wonderful.
S: Well, hey, we had such a long winter; you're right, it's still a little on the cold side. Today there were all these various unmistakable signs of spring, sort of like all at once. So, first, the forsythia is in full bloom. Second, bluebirds have moved into our bluebird house. They're gonna make little baby bluebirds.
R: How do the bluebirds know that the bluebird house is for them?
S: That's a really good question.
E: They use the GPS.
J: They can fit in it.
R: There's a sign.
S: So a bluebird house has an opening of a certain size. But honestly, it's more about positioning. You need to place it three to five feet above the ground, in an open area, with nothing obscuring the ground beneath it. So, bluebirds wanna make sure they can see snakes and other things coming. So if you do that, if you hang it at the right height in a sort of openish area, bluebirds will move into it. I mean it's,
R: And no other bird?
S: Well, hang on. The other bird that will tend to steal a bluebird house from the bluebird is the house sparrow. We have plenty of house sparrows, but bluebirds always seem to move into our bluebird houses. So it's remarkably consistent.
J: Rebecca, what do you think, like you have, the pair of bluebirds are flying around and the wife bluebird goes "What about this one, honey?" And the husband's like "Nope, that's only two feet off the gound."
R: Yeah, I mean they definitely have like a measuring tape and a list of wants.
S: It works, it absolutely works.
R: Good view of snakes, in-ground pool.
B: My favorite sign of spring is that the White Walkers are retreating back north.
S: Yup. (laughter and garbled comments) Nice call-back. The robins are more visible. As we learned previously they don't actually; they do migrate, but there are robins in the winter but they stay more in the forest. But the robins that are here come out and are more visible in the spring. And I actually grilled steaks on the grill on my deck today, for dinner.
E: Delicious.
R: Man, you went all out.
S: Yeah. And, the single most profound marker that spring is here was
E: Allergies.
S: No. I don't have allergies luckily. Was, the ice cream truck came around.
R: You have an ice cream truck?
S: Yup. My daughters go insane. You know, they see the ice cream truck and they just go crazy.
E: Come on, you go a little crazy, too. Admit it.
J: Does the guy play music, Steve, or
S: Of course.
J: Does he ring the bell, what is it?
S: Of course, you've got the music and the bell and they just lose their minds.
R: We never had an ice cream truck when I was a kid; it was too rural.
B: We did.
S: Oh, yeah, we did.
B: Jay, you were insane. I have a distinct memory of you, one night, sitting at the end of our driveway. You were a little shit, probably six or seven, crying your eyes out because the ice cream man didn't come, or you missed him, or something, and you were just like bawling 'cause you wanted your ice cream, and you missed it. (laughter)
J: I never forgave that guy, either.
E: That bastard.
