Maker’s information is the distinctive understanding of a factor by the one that made it. Creator and Make: contributor Invoice Gurstelle talks about his books, his favourite tasks and his ongoing examine of the historical past of science and expertise, the place the idea of Maker’s Information has been developed. It’s information solely accessible to the one that has made the factor.
Invoice Gurstelle was educated as a mechnical engineer however began a profession on the aspect writing technical books with how-to tasks. His first guide, revealed in 2001, was “Yard Ballistics.” His three-volume, Remaking Historical past, is revealed by Make:. On this dialog, I discuss to Invoice about how he acquired began writing books, how began writing for Make, and focus on his favourite challenge, a spud gun. A cool model, a see-thru potato cannon, the Evening Lighter, was revealed in Make:. One in every of his harder tasks was the Ornithopter.
Invoice Gurstelle
We focus on two journeys that we took collectively:
He talks about finding out the historical past of science and expertise. We focus on James Watt’s flyball governor and the invention of the steam engine. In Quantity 79 of Make:, the Boards concern, we publish “Elevate Water by Fireplace”, Invoice’s recreation of Thomas Savery’s proto-steam engine, the primary industrial machine to make use of fossil gasoline. His subsequent “Remaking Historical past” challenge for Make: will take a look at a tool that lets you see underwater — the aquascope or bathyscope.

Transcript
Invoice: Maker information, when you pare it down actual merely, is that the issues that you simply make present — when you make one thing, you’ve gotten a greater understanding of the way it was made, why it was made, when it was made than anyone else. That’s maker’s information.
Dale: Welcome to Make:forged. I’m Dale Dougherty.
I’m joined at present by Invoice Gurstelle, who’s a creator of many non-fiction books which we’ll cowl right here. He’s a columnist in make. We’ve additionally revealed a number of of his remaking historical past books, three of them to be actual.
Invoice, the place are you proper now?
Invoice: I’m in my workplace in St. Paul, Minnesota, the place it’s very chilly at present. It’s three levels above zero. And it’s sunny although. That’s one thing.
Dale: That’s good. I assumed I’d ask you– how did you first turn into a guide creator? What even made you consider doing that? And the place had been you in your life and the way do you know that’s one thing you needed to do?
Invoice: This is able to be about I’m going to say 19 98, 19 99. So it’s been a very long time since I’ve been doing this.
On the time I’ve a level in mechanical engineering and I used to be working as a mechanical engineer. I truly was was a registered engineer within the state of Minnesota. And that was my full-time job. That’s how I supported myself and my household. nicely, 1998 determined that, I wasn’t completely concerned in my occupation.
So I wish to do one thing in my very own spare time. And what I’ve at all times appreciated to do is make issues, simply make my very own issues. And, the extra thrilling it was, the extra consideration I may get from different individuals who, who noticed me make issues the higher. I appreciated that. I made a decision that I’d kinda make an inventory. These are the very early days of the web, Dale. And I’d look on-line, I’d see what different folks had been making. And boy, this was all, no one was doing something like that on the time, however I discover these actually bizarre issues on Usenet and listservs and issues of different individuals who make issues and it impressed me. It actually did. So I made a decision I’d make a guide of a ten, 15, no matter actually thrilling issues to make. So I went forward and did that. After which after I checked out it, I mentioned, huh, that’s fairly cool. So I gave it the identify, Yard Ballistics, and I made a decision I used to be going to have the ability to self publish it. I purchased a guide on the best way to self publish your personal guide.
And I mentioned print it out, make a bunch of Xerox copies, the time you exit to Kinko’s or some copy store and get a bunch of them. And I made, I don’t know, perhaps 25 copies and I despatched them out to well-known scientific and technical folks. And I mentioned, please evaluate this guide so I can get a again cowl blurb, and I simply despatched it out. There simply aren’t a variety of, even on the time of scientists who’re like on a regular basis names, moreover Stephen Hawking. Yeah, the place are you going to go? Stephen, Jay Gould. He was lifeless. He simply died. There simply weren’t a variety of them.
So I’d ship them out to whoever I may consider. I mentioned about to astronauts, so I despatched it out to Carl Sagan’s widow. I despatched it out to a lady named Dana Sobell, who was the chief science correspondent on the New York Instances. And he or she beloved my guide. She mentioned, that is nice. That is what the world wants.
She doesn’t know me from Adam. And he or she says, Invoice, I’m going that will help you. So she gave me the identify of her writer. And I talked to them and so they appreciated it. They didn’t prefer it sufficient to publish it, however they appreciated it sufficient to search out me an agent who finally acquired my guide revealed. In order that was my first guide, Yard Ballistics.
And I acquired to let you know it’s offered and offered. I couldn’t imagine it. And I began making some good cash. And I mentioned I’m gonna do a second guide. So I did a guide on making robots, fight robots. This was when BattleBots was all the large rage. So me and my son, Andy, we’d make BattleBots not Battle Bots. They’re truly a special league, nevertheless it was similar form of factor. And that offered fairly good too. After which I wrote a guide on making catapults and these are all issues that I had carried out, in my historic previous and by no means thought I may earn a living doing. I appreciated it. I mentioned, that is far more enjoyable than working as a registered engineer.
So I forged my internet huge and it got here throughout Make Journal, which is that this model new startup journal. They had been simply doing loopy stuff, identical to what I needed to do. So I reached out to them, to you, Mark Frauenfelder was the editor in chief on the time, and we acquired alongside famously and I’ve simply been doing that ever since.
Dale: So how do you know that? Did you are concerned that there was an viewers for yard ballistics? Or did you simply publish it hoping there was?
Invoice: Like I mentioned I used to be going to publish it myself, however as a result of I acquired an agent, my agent acquired a writer is as much as them to promote it. It was a extremely good writer. It was top-notch writer and so they actually ran with it. Received nice publicity and the guide offered and offered. So did I fear? No, it wasn’t. Yeah, it’d be good if it offered nicely, however I wasn’t investing in it cash.
Dale: Do you suppose say that is the late nineties once you publish that guide and it’s what results in Make in some methods. I spotted that there are a variety of tasks that perhaps, a brand new technology had by no means carried out. They weren’t new essentially. It’s constructing a trebuchet or one thing like that, however a variety of enjoyable and fairly cool. You could possibly definitely current them as faculty tasks in one other mild when you needed to.
However the thought was that is thrilling and enjoyable to do. And perhaps it’s somewhat harmful, or perhaps there’s issues in right here that folks aren’t telling you that you could possibly do these items and it opens up an entire new world to you. Oh racing vehicles or one thing. Yeah. It’s somewhat harmful, nevertheless it’s enjoyable, folks love to do it.
Invoice: However the hazard is an enormous facet. I used to be the primary man to essentially give you tasks that mentioned, okay, you’re by yourself. There’s no assure of your security. When you’re going to do these items, it’s on you. I’ve carried out these items. I’ve carried out them safely. When you don’t comply with instructions, even when you do comply with the instructions, you’re nonetheless by yourself.
Individuals accepted that. And I feel that was new and it actually labored out. That’s why the books are standard. That little facet of hazard is perhaps overstating it, however there are some dangers right here. When you didn’t do it, issues can go haywire in a foul means.
Dale: And to some extent, culturally folks telling their youngsters to not do these items and the children go, man, I may do that. I may not inform my mother and father, however I’m going to exit and do it.
Invoice: The preferred challenge in Yard Ballistics, some of the standard challenge in any guide I’ve ever written is one thing referred to as a potato cannon, a spud gun. Everytime you need a tuber shooter, no matter you wish to name it. And when you make one, you go and it really works the primary time you shoot it, it’s POW, it’s a visceral shock to your system since you made one thing so highly effective, so noisy, so loud, and but it really works. In order that’s fairly cool.
Dale: Yeah, undoubtedly. You probably did a model of that in make, the Evening Lighter, I feel.
Invoice: Yeah, that was, I feel it was quantity 4 if I’m not mistaken, however yeah, I did. I did that. And I made that one on a transparent PVC. So you could possibly truly see the explosion within the combustion chamber and that’s fairly neat.
Dale: Is there one other challenge out of your books that’s a favourite of yours?
Invoice: I really like all my youngsters equally. In my books? There are lots, they’re all completely different, in order that’s a tough query. I feel perhaps a query I may reply for you is, I’ve written a variety of columns and articles for make journal. And I look again and there’s some, I’m tremendously happy with.
I’m happy with all of them. I don’t suppose I’ve ever mentioned, boy that is actual stinker as a result of I wouldn’t ship it to you if it was. However early on I made one thing actually difficult, referred to as an ornithopter. Have you learnt what an an ornithopter is?
Dale: Yeah.
Invoice: It’s a it’s like an airplane that flies by flap. Okay. It doesn’t have a propeller. It flaps its means by means of the sky. And early on, I constructed a an ornithopter round out of a rubber bands and balsa wooden, and we revealed that in make, and that was a problem. I don’t suppose I’ve ever spent extra time on a challenge trigger it’s actually laborious to get their dynamics proper. It must be so mild Dale. It’s actually laborious to get an order seem to fly, however I acquired it. It lastly flew after which I revealed it and I felt that was fairly cool. I appreciated that.
Dale: Did you ever hear from those who it was tough for them or that it labored or it didn’t?
Invoice: I didn’t, I don’t get tons of suggestions. Individuals simply don’t write to magazines. And once more, this is able to be, Within the early two hundreds. So there wasn’t a variety of e-mail or perhaps there was, however I don’t keep in mind getting a lot, I did one other one which I appreciated and I appreciated this as a result of it’s so intelligent. I’m at all times happy with myself.
James Watt. He didn’t invent the steam engine, however he improved it an excellent deal and made it sensible. And it powered the entire industrial revolution. And one of many issues Watt did was he made one thing referred to as a flyball governor, a centrifical governor that managed how briskly the steam head would spin round since you don’t need it to go uncontrolled. And perhaps you’ve seen these items. There are these balls on the tip of rods and the quicker the factor spins round, the upper the balls go up into the air and the upper the balls go up within the air, the tougher it’s for the machine to show. So it maintains a valve at a set opening.
I recreated that for a Make journal article. And, there’d be a variety of machining and there’d be a variety of expense in making an actual James Watt flyball governor. However I used to be capable of give you a extremely cool analog and I don’t keep in mind which concern it’s, nevertheless it actually works surprisingly nicely.
And I talked to the editor. I used to be working with a person named Keith Hammond and we each loved that one fairly a bit. I used to be very happy with that one. I’ve most likely carried out over 50 tasks, so there are most likely different ones I appreciated simply as a lot, however that involves thoughts.
Dale: I used to be taking a look at this concern of Make, talking of the commercial revolution, you’ve gotten a challenge in there. The steam engines actually first form of invented in that interval to, to take water out of the mine. And so on this one, you’re speaking in regards to the first machine to make use of fossil gasoline to try this, proper?
Invoice: So James watt, when he’d been on the steam engine. His work trusted any individual named Newcomen proper. And Newcomen’s work rested on any individual referred to as Thomas Savery and Thomas Savery invented the primary machine ever to make use of fossil fuels to do helpful work. And principally it might warmth up a cylinder and then you definately would shut the cylinder. So you’ll warmth up a cylinder by filling it filled with steam, then you definately’d shut the valves off. So there was steam trapped inside that cylinder, and then you definately would pour chilly water on it. And when that occurred, the steam would condense. And when the steam condenses, it pulled the vacuum and then you definately’d open up a valve and that vacuum would pull water up out of the mine.
And that was Savery’s good thought. Once more, to make an actual engine, you must have a lathe, and a mill and all this, however on this concern, I suppose it’s the most recent concern. So I’m glad you introduced it up. Individuals may take a look at it if they’ve it in entrance of them. You possibly can see how Thomas Savery invented this good machine. It doesn’t have a piston. It’s actual easy, nevertheless it does pump. Not effectively, nevertheless it pumps water prefer it’s purported to.
Dale: I discover it attention-grabbing, just like the origins of expertise generally, as a result of what was the issue that was dealing with them? We have a tendency to consider steam engines for transportation — trains and boats and issues –however, it was initially, it was transferring water.
Invoice: That they had all these coal mines in Britain and so they’re filled with water. You dig down, you get water and so they had guys with buckets hauling them out. In order that they wanted one thing higher.
Dale: You and I, within the early days of the journal, acquired to take a number of journeys collectively that had been simply awfully enjoyable.
Each time that Halloween comes round, it makes me consider the Punkin Chunkin contest in Delaware, And also you had been the right individual to convey alongside as a result of it’s a discipline of trebuchets, catapults and all these items. And to present some colour to it, a few of these the air cannons notably are massive. They’re painted colours, they’ve humorous names and their crew usually seems to be like a NASCAR workforce, they’re all decked out in pressed pink shirts which have logos on them. I don’t suppose anyone makes cash at a punkin chunkin contest. They could win cash at NASCAR. Individuals spend a few days in a Delaware cornfield, hurling these pumpkins. And I don’t know in case you have a reminiscence from that point.
Invoice: In fact I do. It was an enormous second in my life. One thing I’ll always remember. When you ever, as a result of I used to be a part of the press. I had an excellent press credential. I may get behind the road to get again with the fellows who’re truly hurling the pumpkins, and as you say, there’s completely different sorts of pumpkin chunkers.
The largest ones are these gigantic air cannons. They usually’re big. They’re simply huge. They usually’re constructed to toss a pumpkin, a ten pound white pumpkin as a result of white pumpkins are actually laborious and so they’re constructed to toss them so far as they’ll presumably be tossed. We had varied groups and as you talked about, the groups had actual personalities, actual personalities.
So that you had some groups that had been like these engineers. They’d have CAD CAM drawings and so they’d have all the pieces found out. And it was very nice. And then you definately’d have groups that had been simply — I feel most likely hillbilly is a pejorative time period, however they had been identical to guys who simply began pounding and welding and see what comes up and, they’d just do pretty much as good, simply in addition to the engineer groups.
And there was no love loss between the great previous boys after which the faculty youngsters, They didn’t love one another, however they each made a imply pumpkin chunking machine.
Dale: Yeah, they did. And it was enjoyable to speak to those folks as a result of it was an enormous a part of their life.
And I recall he had, when he’s air cannon rigs, it is perhaps, 70 toes lengthy and. And I mentioned the place does this go once you’re not at Punkin Chunkin. He says my entrance yard.
He’s like someplace in rural Virginia, I feel, and simply parks it there. The one I additionally keep in mind was an enormous iron catapult, Yankee Siege. Do you keep in mind that one? And it’s 50 toes, 55 toes tall.
Invoice: I keep in mind that it was Yankee Siege. And the man who constructed it was a dentist. A New Hampshire dentist. And he’d spend hundreds on this factor. They usually was so large that after I keep in mind after they erected it at Punkin Chunkin, they’d herald a crane. They would want a rocket crate and simply to set all of it up, it was so large. However that factor may actually toss nicely.
Dale: I keep in mind asking him. Did you construct a bunch of smaller ones after which ultimately you get to 55 toes tall. He mentioned, no, that is the primary one I’ve ever constructed!
The opposite remark that I made was that this man’s obituary, though he’d been a dentist all his life locally, will say builder of Yankee siege and the 55 foot tall catapult.
Invoice: Yeah. You bought to listen to that. That simply exhibits some form of actually cool craziness. Wow.
Dale: Then the origin story of Punkin Chunkin was that it began as a bar competitors regionally that, they had been throwing pumpkins after Halloween. And ultimately they acquired round to say may we do that with a machine. And it went loopy from there. And we most likely hit it in about its heyday trigger I feel it did dissolve.
Invoice: Doesn’t exist anymore. Great things at all times dissolves. It’s too unhealthy.
Dale: The opposite occasion we went to was the Osh Kosh Air Present. I’ve been twice I imagine. That’s the final word DIY challenge to construct your personal aircraft. And there’s, that is what we discovered from is I assumed it’s fascinating. It’s organized by the EAA, which is Experimental Aviation Affiliation. They usually got here collectively after World Battle Two to largely as a result of insurance coverage corporations wouldn’t insure personal planes. And folks couldn’t fly and so they handed laws saying when you constructed greater than 50, I feel it’s 51% of your aircraft your self, and you could possibly fly it.
You didn’t want insurance coverage. And so it launched a complete trade of individuals constructing their very own planes, equipment planes. And that’s kinda what the core of the present remains to be is folks, nevertheless it’s so cool. I’m not a pilot or something. Individuals fly into the present and so they camp out subsequent to their aircraft and folks come from throughout.
It actually felt like a Maker Faire form of occasion as a result of folks. They do and so they like to speak store, they like to face round, their aircraft. The opposite factor that I keep in mind was what perhaps inform the story in regards to the Breezy pilots.
Invoice: You’re proper. There’s a variety of house constructed plane there. In case anyone’s . I suppose the most affordable airworthy craft is known as the Breezy. It’s a equipment craft, and it’s actually quite simple. You purchase wings. You don’t make the wings, you purchase the wings, however then you definately purchased these wings to what seems to be like an outsized stepladder turned on its aspect.
After which it had a 65 horsepower pusher, a 65 horsepower pusher prop, pushing, pointing backwards. So it pushed you and then you definately would make the management stuff. After which principally the proprietor would mount like garden chairs on this actually skinny metallic body. And you’ll take it up within the air and it’s there’s actually not a lot — let’s put it like this. There’s nothing between you and the air round you. You’re simply sitting there on high of anothin’ in a garden chair at 900 toes and it’s a real expertise. Let me let you know, as a result of the man gave me a trip on his Breezy. There’s the pilot who’s in entrance of me after which there’s a chair that’s huge sufficient, simply huge sufficient for 2 folks, in again of the pilot. So he took me and this 11 12 months previous woman and she or he mentioned, we’re going up. So we go up. I had a digital camera and I get fearful of heights, however what, in a traditional airplane, no one thinks about it. However on this, I used to be simply petrified the entire time, simply petrified.
And I knew I, okay, I’m up right here. I’m a journalist. I acquired to take some photos. So I do all the pieces I may to get my digital camera up and I pushed the button, put it down and oh, I’m so scared. I’m so scared. And this 11 12 months previous woman subsequent. She’s having a good time. She’s not scared in any respect. She simply thinks that is essentially the most marvelous factor.
And I used to be like, oh, get me down. However I didn’t truly cry out, however I felt prefer it. It was fairly the expertise. Let’s put it like that.
Dale: I keep in mind the guy we had been speaking about. He flew his aircraft from Texas all the way in which as much as Wisconsin. He mentioned,, , we may see a storm coming and we’d attempt to get away from it to the proper. Or we’d ultimately land if it was unhealthy, however he had no safety. And it was nearly like being a dare satan to try this, however he additionally mentioned that industrial airline pilots needed to fly his aircraft due to simply the feeling of flying that you simply had been up within the air, wind in your face, it was as uncooked because it could possibly be.
They usually don’t really feel any of that in a industrial airliner.
Invoice: Yeah. It was like being Daedalus up there. It’s simply an unmediated climbing expertise. You actually are simply up there. It’s cool.
Dale: To return to historical past a bit, you’ve actually been finding out and dealing and taking a look at makers making up to now and taking a look at what inventors and different folks, scientists and others have created. You’ve three books and why don’t you speak about how these are structured?
Invoice: Yeah, I’d like to. So I’ve three Remaking Historical past books, that are revealed by Make and what they’re is they’re tasks that I’ve give you which can be a mixture of initially expertise or science, historical past and DIY. So that you combine science historical past and DIY collectively, and that’s what you get. You get these Remaking Historical past books. Remaking historical past means like we’re remaking this historical past. We’re studying historical past by making vital historic issues. So there’s three books and every guide covers a selected interval in historical past chronologically.
I don’t keep in mind off the highest of my head what the precise demarcations are, however you’ve acquired early, then you definately’ve acquired the traditional world by means of medieval instances then you definately’d have principally the scientific revolution by means of the enlightenment and then you definately’d have all the pieces that went after that.
Dale: Fashionable.
Invoice: And the entire thought is that every challenge is a few vital little bit of expertise or a scientific experiment, like an instrument of some type and also you recreate these. They usually’re not precisely recreations, however they’re purposeful recreations. They present what that was about.
And I simply fell in love with this entire thought of recreating historical past to search out issues out as a result of you possibly can study lots. When you’re a historian, I consider myself as an historian as a occupation. Now there’s a variety of stuff that’s not accessible by studying textual content. You possibly can’t discover notes from each scientist of what they did within the laboratory or something.
There’s a variety of unanswered questions. So when you’re going to search out new data, study extra about how folks truly went by means of this act of innovation and creating and no matter. Typically a great way to get better that data is to attempt to remake it your self. And that’s what I that’s what I’ve been concentrating on for the previous few years. It’s attention-grabbing.
Dale: It does essentially get to the query of how do we all know one thing, or how, that individual is attempting to construct one thing to study one thing or uncover one thing.
Invoice: There’s a bunch of philosophers– you’ve heard of Francis Bacon.
Sure. Ever heard of a man named Vico. V I C O.
Dale: No, I don’t suppose so.
Invoice: Okay. There’s an entire group of what I name early trendy philosophers, who actually thought lots about science and expertise. They usually got here up with this idea that — it was an idea that was well-known on the time they wrote, as a result of they wrote about it.
It’s referred to as maker’s information. It’s truly one thing proper alongside your line. The thought of maker’s information, and it’s a extremely heavy philosophy of science idea that folks spent their careers investigating the nuances of maker’s information. And maker information when you pare it down actual merely is that the issues that you simply make present, when you make one thing, you’ve gotten a greater information understanding of the way it was made, why it was made, when it was made than anyone else. That’s maker’s information.
And When you take a pocket watch. Okay. And also you give it to me. It’s my watch now. I can take a look at it and say, sure, it’s 4 o’clock and I can wind it, however I don’t know all the pieces about that. And I can take it to a watch repairman or a lady, and so they can go in there and repair it, however they don’t know all the pieces about it.
How, why it was made the way in which it was made? Why are there that many tooth on the gears? Why are these gears specified by that means? Solely the maker of that might know. That’s referred to as maker’s information. And it’s a extremely wealthy space to discover traditionally, as a result of when you get into the maker’s information idea of, into the heads of the people who find themselves making.
You will discover out a variety of stuff and never going to love, there’s a variety of philosophers who speak about this, nevertheless it’s one thing that I’ve been in.
Dale: That’s an excellent time period. I’ve been fascinated with the time period these days “know-how,” which is in that space.
Training is an abstraction of information proper now. Like they’re distilling one thing and you may’t know the way it was created or the way you, how that’s true. However know-how is linked to the method of creating. And the way did you get from there to there? Together with all of the errors and lifeless ends that occurred there.
So inform me you’re late in life, you determined to return to varsity.
Invoice: Late in life.. I suppose so
Dale: You’re not a 19 12 months previous on campus.
Invoice: I’m not a 19 12 months previous on campus. And I really feel that increasingly more as I walked by means of campus. However once you attain a sure age within the state of Minnesota, you possibly can go go to highschool for not very a lot cash. It’s low. They figured you’re too previous, however you do get credit score for it.
So I went again to highschool only for the heck of it, began taking a few lessons in historical past and appreciated it. So I made a decision that reasonably than going after more cash or one thing, what I wish to do is go after information. So I utilized and was accepted to the this system the doctoral program, the College of Minnesota within the historical past of science, expertise and drugs.
And I’ve been on that program. That is my third 12 months now, after I’m engaged on my preliminary exams. After which after I move that, then I begin to write my dissertation, nevertheless it’s been it’s been a variety of work, however actual rewarding. It’s enjoyable and irritating on the similar time. However I’m studying lots and I’m staying occupied and if all the pieces seems, I don’t actually plan to get a job as a university professor. I’m carried out.
That’s not my curiosity, however what I do plan on doing is including physique of information in regards to the issues that nicely, each you and I are curious about. And doubtless different makers as nicely. And that’s the place I’m at proper now.
Dale: That’s cool. Is there an an period that you simply concentrate on in time or historical past that you simply’re taking a look at?
Invoice: Yeah, that’s a extremely good query. Each period has cool stuff. Simply by default, I’ve spent extra time what they name the early trendy interval. So we’re going to say from principally the tip of the Renaissance to the commercial revolution. So this is able to be the fifteenth, sixteenth, seventeenth, 18th centuries, which is, I grant you, that’s a really lengthy window, however that’s my window.
Dale: Terrific. What’s your subsequent column in Make about?
Invoice: So my subsequent challenge for Make journal is, It’s not very difficult. It’s actually easy, nevertheless it’s actually cool. There was a lady don’t ask me her identify.
Dale (2): It’s Sarah Mather.
Invoice: I don’t keep in mind now ladies inventor who labored in New York on the time of the Civil Battle and her challenge or the factor she needed to make was a means for the Navy to look down into the water and see what was occurring beneath the ship when it comes to coping with the propeller or the hull, or see what’s down there. So she invented one thing referred to as a aquascope or a bathyscope. Okay. And principally it’s a tool that, you possibly can’t actually look by means of the water as a result of the optics aren’t good.
You’ve that mild reflection and refraction. So the bathyscope lets you punch down beneath the water and get an excellent view. A very good clear view of what’s occurred. So our subsequent challenge takes us this good girl inventor’s thought and simplifies it and permits folks to look beneath the water on their very own.
So I’m wanting ahead to it getting that one carried out..
Dale: Invoice, thanks for spending time with me at present. It’s nice to reconnect and good luck in your research. Thanks once more for writing for make. And we look ahead to studying about your bathyscope challenge.
Invoice: Okay, thanks for having me. I loved being right here.
