 Aoi Kasamaru : Later! |
(0:00:07.01) |
 Ruri Tanigawa : See ya! |
(0:00:08.14) |
|
Ruri Tanigawa : Let's see, what to do once I get home? |
(0:00:10.37) |
|
Ruri Tanigawa : First thing's first. Ice cream! |
(0:00:14.00) |
|
Ruri Tanigawa : He did? |
(0:00:32.60) |
|
Ruri Tanigawa : No way. I don't remember that. |
(0:00:37.85) |
|
Ruri Tanigawa : Hey, that reminds me. |
(0:00:48.48) |
|
Ruri Tanigawa : Didn't you say that Grandpa used to collect rocks? |
(0:00:50.47) |
|
Ruri Tanigawa : Really?! Do we still have them? |
(0:00:59.45) |
Ruri Tanigawa : What?! Can I borrow the keys?
Lemme go check! |
(0:01:05.82) |
|
Ruri Tanigawa : It's so dusty in here. |
(0:01:16.48) |
|
Ruri Tanigawa : But I might find quartz. |
(0:01:19.89) |
|
Ruri Tanigawa : Or something even more rare. |
(0:01:22.03) |
|
Ruri Tanigawa : That box smells like treasure. |
(0:01:25.51) |
|
Ruri Tanigawa : Ouch... |
(0:01:36.05) |
|
Ruri Tanigawa : What's this thing? |
(0:01:39.38) |
|
Ruri Tanigawa : Suoh Tanigawa? |
(0:01:41.14) |
|
Ruri Tanigawa : I dunno, but I found two rocks inside. |
(0:01:54.69) |
 Shouko Seto : Along with copper wire
and a coil, it looks like. |
(0:01:57.78) |
Ruri Tanigawa : I think it was my grandpa's,
since the box is labeled ＂Tanigawa.＂ |
(0:02:01.40) |
|
Shouko Seto : I wonder what this card is. |
(0:02:05.78) |
|
Aoi Kasamaru : 'Sup? |
(0:02:07.97) |
|
Aoi Kasamaru : What's that box? |
(0:02:11.13) |
|
Ruri Tanigawa : That's the thing, we don't know! |
(0:02:12.65) |
|
Ruri Tanigawa : But we're guessing it's related to rocks. |
(0:02:14.80) |
|
Aoi Kasamaru : Did you switch up your hobbies or something? |
(0:02:17.86) |
Aoi Kasamaru : I thought you were into stuff
like jewelry and makeup. |
(0:02:20.13) |
|
Ruri Tanigawa : I still am. |
(0:02:23.16) |
|
Ruri Tanigawa : I just like this stuff now, too. |
(0:02:24.50) |
|
Aoi Kasamaru : Huh. |
(0:02:27.20) |
|
Aoi Kasamaru : Lemme see. |
(0:02:29.70) |
|
Aoi Kasamaru : Shoot, something rolled away! |
(0:02:33.46) |
|
Aoi Kasamaru : Found it. |
(0:02:37.88) |
|
Aoi Kasamaru : S-Sorry, did I break it? |
(0:02:40.85) |
|
Ruri Tanigawa : I dunno. |
(0:02:45.14) |
Ruri Tanigawa : I'm not even sure if it was
working in the first place. |
(0:02:46.31) |
|
Aoi Kasamaru : Oh. |
(0:02:50.55) |
|
Ruri Tanigawa : Hmm... Maybe Nagi-san would know. |
(0:02:52.09) |
 Nagi Arato : It's a crystal radio. |
(0:03:00.93) |
|
Nagi Arato : You don't see these every day. |
(0:03:03.57) |
|
Nagi Arato : And it doesn't look commercial. |
(0:03:05.18) |
|
Nagi Arato : Is it homemade? |
(0:03:07.61) |
|
Ruri Tanigawa : Hold on, Nagi-san. How can you tell? |
(0:03:08.66) |
Nagi Arato : Well, it's obvious if you look
at the coil and detector. |
(0:03:13.30) |
|
Nagi Arato : What else could it be? |
(0:03:16.76) |
Nagi Arato : That bundle of copper wire
you've got is the antenna. |
(0:03:18.65) |
|
Nagi Arato : And this is the ground. |
(0:03:21.71) |
 Youko Imari : Self-made ones are rare to come by nowadays. |
(0:03:23.28) |
Youko Imari : Looks like it was made
sometime after World War II. |
(0:03:26.03) |
|
Shouko Seto : Nowadays? |
(0:03:29.72) |
|
Youko Imari : Have you guys ever heard of them? |
(0:03:31.11) |
|
Youko Imari : They used to be popular as magazine freebies. |
(0:03:33.78) |
|
Shouko Seto : Crystal radios came with magazines? |
(0:03:36.82) |
|
Ruri Tanigawa : By radio, you mean that
radio, right? |
(0:03:39.65) |
|
Nagi Arato : That's right. |
(0:03:43.37) |
|
Ruri Tanigawa : B-But... It's so bare
looking. |
(0:03:44.26) |
Nagi Arato : Actually, it's pretty old,
but it looks like all the parts are here. |
(0:03:47.83) |
|
Shouko Seto : But where do you put the batteries? |
(0:03:52.73) |
|
Youko Imari : Seto-san, what a great question! |
(0:03:55.46) |
|
Youko Imari : Crystal radios don't require batteries. |
(0:03:58.01) |
|
Youko Imari : The radio waves themselves carry energy, |
(0:04:00.99) |
|
Youko Imari : so, it just converts that energy into sound. |
(0:04:03.09) |
Youko Imari : First, the antenna and ground, or the
aerial circuit, pick up the radio waves. |
(0:04:06.38) |
Youko Imari : Then, the coils and condenser,
or the tuning circuit, select the signal. |
(0:04:11.26) |
Youko Imari : Finally, the detector, or detection circuit,
extracts the audio signal. |
(0:04:15.65) |
Youko Imari : When a mineral is used as the detector,
it's called a crystal radio. |
(0:04:19.30) |
|
Shouko Seto : Th-That was a bit hard to follow. |
(0:04:24.43) |
|
Shouko Seto : So the mineral... |
(0:04:26.63) |
|
Youko Imari : Converts radio waves into sound. |
(0:04:27.98) |
|
Ruri Tanigawa : I don't really get it, but it's cool! |
(0:04:30.19) |
|
Nagi Arato : Ruri, did this radio come with any earphones? |
(0:04:33.17) |
|
Ruri Tanigawa : Earphones? |
(0:04:36.85) |
Nagi Arato : Yeah. Radio signals received
through crystal radios |
(0:04:37.98) |
Nagi Arato : aren't strong enough to output
through a normal speaker. |
(0:04:41.25) |
|
Nagi Arato : So it should require special earphones. |
(0:04:44.85) |
|
Ruri Tanigawa : I don't think so... |
(0:04:47.71) |
|
Ruri Tanigawa : We can't listen to it without them? |
(0:04:50.56) |
|
Youko Imari : No worries! |
(0:04:53.54) |
|
Youko Imari : I've got one right here! |
(0:04:58.29) |
|
Youko Imari : Modern standard earphones usually have |
(0:05:00.65) |
Youko Imari : an impedance or electrical
resistance of 20–30 ohms, |
(0:05:03.46) |
Youko Imari : but crystal radios require earphones
with several thousand ohms. |
(0:05:08.33) |
Youko Imari : That's why we use this crystal
earphone made with Rochelle salt. |
(0:05:12.69) |
|
Ruri Tanigawa : Impe—what? Who's Rochelle? |
(0:05:16.75) |
Youko Imari : In other words, crystal earphones can
convert even weak signals into sound. |
(0:05:19.57) |
|
Nagi Arato : Yeah, but this coil is pretty worn down. |
(0:05:24.87) |
|
Nagi Arato : You're probably better off building a new one. |
(0:05:27.69) |
|
Ruri Tanigawa : Coil... Then I'll be able to listen to it? |
(0:05:30.42) |
|
Nagi Arato : Yup, I think so. |
(0:05:34.32) |
|
Ruri Tanigawa : I wanna hear what it sounds like! |
(0:05:39.40) |
|
Shouko Seto : Me, too! |
(0:05:40.93) |
|
Nagi Arato : Great, then let's gather materials. |
(0:05:42.42) |
|
Youko Imari : But Arato-senpai. |
(0:05:45.10) |
Youko Imari : Don't you need to compile
that data by next week? |
(0:05:47.05) |
|
Shouko Seto : Arato-san seemed pretty busy. |
(0:06:03.14) |
|
Ruri Tanigawa : And Imari-san has a report due, too. |
(0:06:05.98) |
Shouko Seto : They were nice enough to tell us
everything we need, but... |
(0:06:09.74) |
|
Shouko Seto : What should we do? |
(0:06:12.63) |
|
Shouko Seto : Do you want to wait until they can help us? |
(0:06:16.16) |
|
Ruri Tanigawa : Let me think... |
(0:06:21.41) |
|
Ruri Tanigawa : Seto-san, are you free after school tomorrow? |
(0:06:27.79) |
|
Ruri Tanigawa : Do you think we can fix it ourselves? |
(0:06:31.95) |
|
Shouko Seto : Yeah, let's do it! |
(0:06:37.93) |
|
Shouko Seto : Enameled wire, sandpaper, a safety pin... |
(0:06:49.68) |
Ruri Tanigawa : What's the difference between
enameled wire and tinned copper wire? |
(0:06:54.20) |
|
Ruri Tanigawa : Does that have to do with the resistance thing? |
(0:06:57.69) |
|
Ruri Tanigawa : What is that, anyway? |
(0:07:01.38) |
|
Shouko Seto : I'm not sure... Maybe how bendable it is? |
(0:07:02.89) |
|
Aoi Kasamaru : Huh? What are you two doing here? |
(0:07:08.53) |
|
Aoi Kasamaru : Well, since I broke it and all... |
(0:07:14.46) |
|
Ruri Tanigawa : You were looking for parts? |
(0:07:17.45) |
Aoi Kasamaru : Yeah. Not that I had any clue
what I was looking for. |
(0:07:19.87) |
|
Ruri Tanigawa : If you wanted to help us, just say so! |
(0:07:24.54) |
|
Aoi Kasamaru : Huh? Help you? |
(0:07:27.92) |
|
Ruri Tanigawa : Yeah. That's what you were up to! |
(0:07:29.43) |
|
Aoi Kasamaru : Oh well. Fine, why not? |
(0:07:35.41) |
|
Shouko Seto : It looks sort of... |
(0:08:05.15) |
|
Aoi Kasamaru : Ugly. |
(0:08:06.58) |
|
Ruri Tanigawa : Did we miss a step? |
(0:08:08.39) |
|
Aoi Kasamaru : Hear anything? |
(0:08:15.87) |
|
Ruri Tanigawa : Not a peep! |
(0:08:17.97) |
|
Shouko Seto : That's weird. |
(0:08:19.69) |
Shouko Seto : The antenna receives radio waves, and then
the coil and condenser select the frequency. |
(0:08:22.75) |
Shouko Seto : The detector converts the radio waves
of that frequency into sound, |
(0:08:30.16) |
|
Shouko Seto : which should get picked up by the earphone. |
(0:08:34.63) |
|
Aoi Kasamaru : How about now? |
(0:08:37.48) |
|
Ruri Tanigawa : Nope, nothing. |
(0:08:39.85) |
Shouko Seto : I don't hear anything either.
We must have made a mistake. |
(0:08:48.50) |
Ruri Tanigawa : There should be radio waves
floating all around here. |
(0:08:54.96) |
|
Aoi Kasamaru : My arms hurt. |
(0:09:02.44) |
|
Nagi Arato : Not a bad job. |
(0:09:07.76) |
|
Nagi Arato : Yeah, you did great. |
(0:09:09.80) |
Nagi Arato : If you can't hear anything after
connecting the antenna and the ground, |
(0:09:13.52) |
Nagi Arato : there might be something wrong
with the detector. |
(0:09:17.04) |
|
Ruri Tanigawa : You mean this? |
(0:09:19.96) |
|
Nagi Arato : This is pegmatite. |
(0:09:22.04) |
|
Nagi Arato : You can't use these as detectors. |
(0:09:24.08) |
Nagi Arato : Many minerals used in crystal
detectors have a metallic luster. |
(0:09:27.66) |
Nagi Arato : Pegmatite is a type of granite that
forms as magma cools and solidifies. |
(0:09:32.09) |
Nagi Arato : It's made up of coarse-grained minerals
like feldspar, quartz, and mica. |
(0:09:37.91) |
Nagi Arato : I think you can find some near
the shrine close to town. |
(0:09:43.87) |
|
Shouko Seto : Is something wrong? |
(0:09:49.98) |
|
Ruri Tanigawa : Why was it in here if it's not even usable? |
(0:09:51.74) |
|
Ruri Tanigawa : Did Grandpa screw up, too? |
(0:09:54.78) |
|
Shouko Seto : What exactly are detectors anyway? |
(0:09:58.93) |
|
Shouko Seto : It's different from tuning, right? |
(0:10:02.12) |
|
Nagi Arato : That would be the coil's role. |
(0:10:04.69) |
|
Ruri Tanigawa : I remember! The coils aren't batteries. |
(0:10:06.68) |
Nagi Arato : Radio waves carrying sound
rise and fall equally |
(0:10:09.46) |
Nagi Arato : in both directions, so you
can't hear anything as is. |
(0:10:12.90) |
Nagi Arato : The detector takes only
one side of this movement |
(0:10:16.06) |
|
Nagi Arato : through a process called rectification. |
(0:10:18.92) |
|
Nagi Arato : That's how you can hear sound. |
(0:10:21.69) |
|
Nagi Arato : At least theoretically. |
(0:10:23.55) |
|
Shouko Seto : Why just theoretically? |
(0:10:26.26) |
Nagi Arato : In these cases, practically anything
could affect the sound. |
(0:10:29.26) |
Nagi Arato : Say, for example, slight
displacement of the antenna, |
(0:10:34.41) |
|
Nagi Arato : or even the part that touches the mineral. |
(0:10:37.23) |
|
Ruri Tanigawa : That sounds impossible! |
(0:10:39.65) |
Nagi Arato : By the way, if you wanna know
the most common choice for detectors... |
(0:10:42.04) |
|
Nagi Arato : There it is. |
(0:10:46.12) |
|
Nagi Arato : It's galena like this. |
(0:10:47.55) |
Ruri Tanigawa : Wait! That's the other
tiny rock I found inside! |
(0:10:51.41) |
Nagi Arato : Galena is a lead sulfide mineral
composed of lead and sulfur, |
(0:10:56.10) |
|
Nagi Arato : and it's the main ore of lead. |
(0:10:59.65) |
Nagi Arato : Besides galena, minerals
like pyrite, chalcopyrite, |
(0:11:02.83) |
|
Nagi Arato : and zincite can also be used as detectors. |
(0:11:06.39) |
|
Shouko Seto : Zincite! |
(0:11:08.84) |
|
Nagi Arato : Why not try a bunch of ore for fun? |
(0:11:10.52) |
|
Youko Imari : Senpai, have those files arrived yet? |
(0:11:14.72) |
|
Nagi Arato : Nope, not yet. |
(0:11:18.10) |
|
Youko Imari : I figured... I'm starting to run out of time. |
(0:11:19.71) |
|
Ruri Tanigawa : Nagi-san, are you still busy? |
(0:11:24.95) |
|
Nagi Arato : Sorry, just for a bit longer. |
(0:11:27.58) |
|
Ruri Tanigawa : Okay... |
(0:11:30.97) |
|
Aoi Kasamaru : Sounds a lot harder than we thought. |
(0:11:40.44) |
|
Ruri Tanigawa : A lot
harder than we thought. |
(0:11:43.84) |
|
Ruri Tanigawa : I bet Grandpa gave up on this thing, too. |
(0:11:46.91) |
|
Ruri Tanigawa : That's why it was in the storage room. |
(0:11:49.12) |
|
Ruri Tanigawa : So it's either unfinished or a bust. |
(0:11:50.87) |
|
Shouko Seto : I doubt that. |
(0:11:54.70) |
|
Aoi Kasamaru : How would you know? |
(0:11:57.19) |
|
Shouko Seto : The proof is here. |
(0:12:00.36) |
|
Shouko Seto : On this card. |
(0:12:01.66) |
|
Ruri Tanigawa : Is that the card that was in the box? |
(0:12:03.20) |
|
Shouko Seto : Yup, I got curious so I dug around. |
(0:12:05.76) |
Shouko Seto : This is a reception verification card,
also known as a QSL card. |
(0:12:08.97) |
Shouko Seto : In other words, whoever owned this radio
confirmed radio reception |
(0:12:14.82) |
|
Shouko Seto : and had this card issued as proof. |
(0:12:20.01) |
Aoi Kasamaru : That reminds me, my uncle does
some ham radio on the side. |
(0:12:24.89) |
Aoi Kasamaru : He always said it was cool connecting
with distant people you don't know. |
(0:12:29.25) |
Ruri Tanigawa : It feels so different from today's technology.
We have smartphones now. |
(0:12:33.35) |
Shouko Seto : But I get why it feels good to
connect with others like that. |
(0:12:38.85) |
|
Shouko Seto : Whether it's today or back then. |
(0:12:43.92) |
|
Ruri Tanigawa : Yeah... You're right. |
(0:12:47.87) |
|
Ruri Tanigawa : Okay! Let's try this again! |
(0:12:58.39) |
|
Aoi Kasamaru : What's this? |
(0:13:14.40) |
|
Ruri Tanigawa : It's garnet. |
(0:13:15.54) |
Ruri Tanigawa : But it might be too small
to use as a detector. |
(0:13:18.38) |
|
Shouko Seto : Manganese might be a good fit. |
(0:13:21.74) |
|
Aoi Kasamaru : Whoa, nice. |
(0:13:24.28) |
Aoi Kasamaru : With all these rocks, we could
make our own crystal radio. |
(0:13:26.65) |
|
Ruri Tanigawa : Great idea! |
(0:13:32.83) |
|
Ruri Tanigawa : All right, let's start with sapphire! |
(0:13:35.03) |
|
Shouko Seto : I'd like to try zincite, too. |
(0:13:37.62) |
|
Aoi Kasamaru : Let's use these weird looking rocks, too. |
(0:13:39.56) |
|
Ruri Tanigawa : Hey, I go first. And handle them with care! |
(0:13:41.49) |
|
Ruri Tanigawa : Huh? I think I hear something. |
(0:13:53.02) |
|
Shouko Seto : Really? |
(0:13:55.02) |
|
Ruri Tanigawa : Yeah. |
(0:13:56.20) |
|
Shouko Seto : I can hear it, too. |
(0:14:00.61) |
|
Aoi Kasamaru : Lemme hear! |
(0:14:01.73) |
|
Shouko Seto : Sure. |
(0:14:02.88) |
|
Aoi Kasamaru : Is this... static noise? |
(0:14:08.61) |
|
Ruri Tanigawa : It sounds kinda like words, too... |
(0:14:11.35) |
|
Shouko Seto : Hang on one second. |
(0:14:14.45) |
|
Shouko Seto : Let's try using this. |
(0:14:19.73) |
|
Aoi Kasamaru : What's that? |
(0:14:22.47) |
|
Shouko Seto : This is germanium diode. |
(0:14:23.89) |
|
Shouko Seto : Imari-san gave it to me the other day. |
(0:14:26.51) |
Shouko Seto : She said we could use it in case
the rocks don't work. |
(0:14:28.51) |
Youko Imari : Germanium diodes have good sensitivity, so
they can receive even weak radio waves well. |
(0:14:33.22) |
Youko Imari : Germanium is a material
that has semiconductor properties. |
(0:14:39.01) |
Youko Imari : Insulators don't easily conduct
electricity, while conductors do. |
(0:14:43.07) |
|
Youko Imari : Semiconductors are in between. |
(0:14:47.97) |
Youko Imari : They conduct electricity
under certain conditions, |
(0:14:49.97) |
Youko Imari : which makes them the best fit
for electronic parts. |
(0:14:52.38) |
|
Shouko Seto : There! |
(0:14:58.29) |
|
Shouko Seto : That should do it. |
(0:15:00.43) |
|
Aoi Kasamaru : You sure? That's it? |
(0:15:02.43) |
|
Shouko Seto : Imari-san told me so. I wouldn't doubt her. |
(0:15:05.06) |
|
Ruri Tanigawa : I can hear it... |
(0:15:15.15) |
|
Aoi Kasamaru : Really? |
(0:15:16.23) |
|
Ruri Tanigawa : Yeah. |
(0:15:17.65) |
|
Shouko Seto : We did it! |
(0:15:18.80) |
|
Shouko Seto : Looks like it's built correctly. |
(0:15:30.01) |
|
Ruri Tanigawa : Yeah. |
(0:15:32.36) |
|
Aoi Kasamaru : Finally, we're done. |
(0:15:34.53) |
|
Aoi Kasamaru : Man, I'm beat. |
(0:15:36.33) |
|
Shouko Seto : Want to call it a day? |
(0:15:38.51) |
|
Aoi Kasamaru : Sounds good. |
(0:15:40.39) |
Ruri Tanigawa : Actually... Can we try again
with that first rock? |
(0:15:41.54) |
|
Aoi Kasamaru : Huh? We got it to work, though. |
(0:15:46.74) |
|
Ruri Tanigawa : But my grandpa got it to work with this. |
(0:15:49.97) |
|
Ruri Tanigawa : So I wanna make it happen, too! |
(0:15:52.89) |
|
Aoi Kasamaru : Fine then. |
(0:15:58.22) |
|
Shouko Seto : But now what? |
(0:16:01.19) |
Shouko Seto : Imari-san and Arato-san both told us
that minerals don't make stable detectors. |
(0:16:03.07) |
|
Shouko Seto : We'd have to make up for it somehow. |
(0:16:08.05) |
|
Ruri Tanigawa : What if the radio waves were stronger? |
(0:16:10.05) |
|
Aoi Kasamaru : How do we do that? |
(0:16:12.15) |
|
Ruri Tanigawa : Oh yeah. |
(0:16:15.00) |
|
Ruri Tanigawa : Go somewhere higher! |
(0:16:17.74) |
|
Ruri Tanigawa : If only Grandpa left me a hint or something... |
(0:16:25.92) |
Ruri Tanigawa : Wait, didn't Nagi-san mention something
about pegmatite around here? |
(0:16:31.81) |
|
Shouko Seto : Yeah, she said we could find some at a shrine. |
(0:16:37.15) |
|
Aoi Kasamaru : Nice, which shrine? |
(0:16:42.08) |
|
Shouko Seto : Umm... I'm trying to remember. |
(0:16:44.28) |
|
Ruri Tanigawa : A shrine... with big rocks... |
(0:16:45.13) |
|
Aoi Kasamaru : There's a few of them around here. |
(0:16:46.69) |
|
Ruri Tanigawa : Suoh Shrine! |
(0:16:53.89) |
|
Aoi Kasamaru : I didn't know they had a festival. |
(0:17:07.45) |
|
Aoi Kasamaru : We should've come then instead. |
(0:17:09.13) |
|
Shouko Seto : It'd be too loud, though. |
(0:17:11.52) |
|
Aoi Kasamaru : Oh yeah, good point. |
(0:17:13.73) |
|
Ruri Tanigawa : Hey, Nagi-san! |
(0:17:18.75) |
|
Ruri Tanigawa : Right now? |
(0:17:20.92) |
|
Ruri Tanigawa : Yeah, we're at Suoh Shrine. |
(0:17:21.95) |
|
Ruri Tanigawa : Huh? Why do you sound so surprised? |
(0:17:25.44) |
|
Ruri Tanigawa : Mhmm. Yeah. |
(0:17:27.60) |
|
Ruri Tanigawa : Okay, we'll wait here. |
(0:17:29.82) |
Ruri Tanigawa : Nagi-san and Imari-san said
they're heading over here. |
(0:17:32.61) |
|
Shouko Seto : What were they surprised about? |
(0:17:35.09) |
|
Ruri Tanigawa : That we were here, I guess. |
(0:17:37.31) |
|
Shouko Seto : What do you mean? |
(0:17:39.50) |
|
Ruri Tanigawa : They said they'd explain later— |
(0:17:40.74) |
|
Ruri Tanigawa : No! I mean—yes! |
(0:17:48.62) |
|
Ruri Tanigawa : Not the shrine necessarily, but... |
(0:17:52.00) |
Ruri Tanigawa : We're looking for a place
to listen to our radio. |
(0:17:53.68) |
|
Ruri Tanigawa : Yes. |
(0:17:59.26) |
Ruri Tanigawa : It's called a crystal radio,
and it belonged to my grandpa. |
(0:18:00.27) |
|
Ruri Tanigawa : It had this shrine's name written on the box. |
(0:18:04.36) |
|
Ruri Tanigawa : Right here. |
(0:18:08.62) |
|
Aoi Kasamaru : You know that guy? |
(0:18:31.67) |
|
Ruri Tanigawa : Nope. Not at all. |
(0:18:33.05) |
|
Nagi Arato : Hey there! |
(0:18:38.65) |
|
Youko Imari : Sorry we're late. |
(0:18:39.74) |
|
Ruri Tanigawa : Nagi-san! |
(0:18:41.60) |
|
Shouko Seto : Imari-san! |
(0:18:42.65) |
|
Aoi Kasamaru : Hey, I'm Aoi. |
(0:18:44.54) |
|
Nagi Arato : You must be Ruri's friend. Nice to meet you. |
(0:18:45.83) |
|
Youko Imari : Good to meet you! |
(0:18:48.69) |
|
Aoi Kasamaru : Yup. |
(0:18:50.21) |
Ruri Tanigawa : Nagi-san, apparently we can
hear the radio by the boulder. |
(0:18:51.29) |
|
Ruri Tanigawa : Come on, let's go! |
(0:18:56.51) |
|
Nagi Arato : Okay, let's see. |
(0:18:59.49) |
|
Nagi Arato : How did you figure this place out? |
(0:19:06.50) |
Ruri Tanigawa : I saw ＂Suoh＂ on the back of the lid,
and it just came to me! |
(0:19:08.74) |
|
Shouko Seto : Why are you both visiting today? |
(0:19:13.45) |
Youko Imari : QSL cards include the coordinates
of the location of reception. |
(0:19:16.36) |
Ruri Tanigawa : Huh? I wish we would have
figured that out sooner. |
(0:19:21.70) |
|
Nagi Arato : This is one giant rock. |
(0:19:40.97) |
|
Youko Imari : Japan's full of spots for megalith worship. |
(0:19:44.00) |
|
Youko Imari : They're thought to house gods. |
(0:19:48.14) |
|
Ruri Tanigawa : Grandpa! |
(0:19:53.88) |
|
Ruri Tanigawa : This spot is it... I can feel it. |
(0:19:57.12) |
Ruri Tanigawa : It feels nostalgic somehow, even though
they're radio waves in the air today. |
(0:20:49.88) |
|
Shouko Seto : It's a weird feeling. |
(0:20:53.92) |
|
Aoi Kasamaru : Let's visit this place again. |
(0:20:55.15) |
|
Ruri Tanigawa : Yeah. |
(0:20:56.76) |
|
Shouko Seto : Sure. |
(0:20:57.79) |
Ruri Tanigawa : I wonder if Grandpa had a hard time
making this crystal radio, too. |
(0:20:59.54) |
|
Ruri Tanigawa : Kinda feels like we're connected across time. |
(0:21:05.57) |
Nagi Arato : The IC cards we use for transportation today
also extract energy from radio waves. |
(0:21:09.33) |
Nagi Arato : They power the IC inside the card,
allowing it to read and write data. |
(0:21:15.06) |
|
Nagi Arato : It's the same technology as crystal radios. |
(0:21:20.60) |
Nagi Arato : So in a way, we still use
crystal radios in our everyday life. |
(0:21:23.53) |
|
Ruri Tanigawa : That's so cool. |
(0:21:28.49) |
|
Ruri Tanigawa : Crystal radios are still relevant today. |
(0:21:30.29) |
Ruri Tanigawa : We're connected...
both in spirit and technology. |
(0:21:33.79) |
|
Youko Imari : I won! |
(0:23:32.34) |
