The Art Of Woodworking: Encyclopedia Of Wood

All right. Let’s do it real, real, real, real, real easy. We’re going to go with the Encyclopedia of Wood. Yeah, those are water bottles down there. Understanding wood. Who’s this guy? All right, so this guy is a… I mean, he’s probably dead now because this book is… This book’s pretty old. But he was, there you go, you can read, University of Tennessee professor of forestry. Okay, look at this guy. Who’s he? He is Andrew Poynter. Wow, that’s crazy, a hundred types of wood to woodworkers around. That’s interesting. What, is this all just different random people? Oh, now he makes the music. Okay. Okay, very interesting.

I did not know all this about a tree, the anatomy of a tree. All right, this is the crown. The branches and leaves of the tree, where… photosynthesis takes place. Okay. The roots, they anchor tree and absorb water and minerals from the soil. Makes sense. Also called the stem or bole, supports the tree and channels nutrients to and from its roots. I mean, that’s kind of self-explanatory. But this is pretty… Okay. This is the pith, a small and often pulpy core running in the center. The heart… Okay, look at this. This is some really random information, whatever. I’ve heard of the heartwood, but I didn’t know that the heartwood was not just… I thought the heartwood was this entire thing right there. I was wrong. It is the entire thing right there besides the absolute middle, and that’s the pith.

Wow, so sapwood that has been clogged with resins, gums and other… Wow. The growth ring. I guess that’s the one you count to see all the trees, a concentric ring divided into earlywood and latewood indicating the amount of wood added to the tree’s diameter in one growing season. Well, in one growing season? How long is a growing season? The ray… what are we looking at, dude? It’s like, these are kind of the same. They’re all kind of pointing to the same thing. Carries nutrients laterally through the wood, also stores nutrients. One part of the tree, the bark. Insulates tree against temperature extremes, keeps sapwood from drying out. So yeah, wow. A tree is really is really… I mean, I understand, and I know that I’m about to say something really stupid, but a tree really is alive.

Wow. I don’t know how to pronounce it, that’s why I didn’t try, but this is basically like the highway. This is what’s bringing all the goodness all around, this thin itty-bitty layer. A thin reproductive layer that forms a new tissue adding to this, and the sap will increase the tree’s girth. This little girth, make it… bigger, wider, thicker. Sapwood, we’ve gone through sapwood a few times. [inaudible 00:04:41] active part of the tree’s wood through which water and minerals are conducted from the roots to the leaves. Also stores nutrients and help support the tree. All right, that’s actually, all this is pretty interesting. I had no idea. I mean, we really weren’t going to get into that, but… What the fuck?

Okay, hardwood and softwood. So what is the difference? I’m guessing this is the softwood and this is the hardwood. I mean, it’s a pretty cool picture. For this one, I’m literally just going to go through the anatomy of a tree and if I have time, maybe softwood and hardwood. But this is, I mean look at the size of that bad boy. I got some trees, but they’re nowhere near that size. And just, like man, this is pretty interesting. If you’ve ever tried to move wood before, it is not an easy task. Wood is really heavy, super heavy. I got myself one of the little mini sawmills, and yeah. Yeah right, not happening. Okay, look at this. The different cutting methods, three methods of sawing logs. They got the plain saw, quarter saw and the through, all to make different types of… Wow, this is interesting. I wonder how they cut that. It kind of seems like you’d get a lot of waste, but they know what they’re doing. Yeah, it’s more into it than just buying a saw mill thing and cutting things down.

Science Encyclopedia

All right. Now, while we were looking at the last one. This probably is not going to be an order. I shouldn’t have said that because it’s not going to make any sense for you guys listening to this right now. However, back over here, right? We looked at the Drives of a Lifetime. It was all right, not my favorite. Let’s go to North American Locomotives. No, I don’t want to look at that one. Science Encyclopedia. I’ll get that. It looks more of a kid book, so a kid book would make it all easy with pictures.

Let’s check it out.

I need to put this book down here so I don’t forget. We got matter…can you see it? my dirty sweater. That’s good enough. Electricity and magnetism, energy, motion, and machines, matter and chemicals. Let’s see, good stuff. This is pretty interesting. See, I told you this is why I like kids books. They draw pictures for you, and there’s always interesting things on the side. For all the kids out there, look at your books now, because once you get to college and everything it’s all text. Let’s look at about time. I got another book around or somewhere with, what is his name? The guy in the wheelchair? I don’t remember what his name is, who wrote all those theses and books on space and time and black holes and whatever. We’ll see if this book over here, which it’s going to do more difficult to film perfectly, but whatever. You guys can hear me. 198.

Look at the pictures. I like these. This guy, here you go. Stephen Hawking. See, I knew what I was talking about. Stephen Hawking. That’s crazy. Space and time, deep space. You also did some things on time. They probably are, more or less, close to get…they got him in there already so they already studied on him. That’s…oh no. This way, maybe? If I’m upside down, I apologize. We’ll just get back to the book. So look. See, this is what I like, kids books are great. They show it real easy for you. You know what I’m saying? They show you the sun and the earth and then we’re outside, and monkeys and…I don’t remember what they’re called. Chimpanzees, maybe? To the Neanderthals, whatever to stone or that the Olympus or whatever it’s called. Then to cities and airplanes and space and space stations. See, this is pretty cool. I Like this.

This is the only page. Look at that. It doesn’t give us too much, but measuring time over years, months, and days are worked out time. We are looking…let’s see. Hopefully you guys can see we’re looking right around here. Hours, minutes, fractions of seconds. The nearest hour or two can be near enough if time is not the essence of traditional events. Minutes, as time keeping devices became more accurate minutes counted as when catching a coach or train. Fractions of seconds, with electronic timing, one or two hundreds of a second can now mean a new world record.

That’s pretty interesting. Like I said, I’ll go more in depth on the paper. What I’m probably going to do is go a little bit more in depth because that page that doesn’t have very much, on that one page, but we’ll probably go deep space. No, because time and deep space aren’t really connected. Time and changing times, right? Changing times and past and future, there we go. All three of those right would be great, but not like…this is what I mean by more or less like a kids book. You can learn a lot from a kid’s because they put pictures in and they make it really simple. You’re not going to learn, especially with these experiments, we can try these out, one of these days. Optical illusions, seeing is believing. we can learn about mold.

Especially if you have kids, get this and then they showed you how to do everything, right? Where did it go? Did you know, as the Earth’s climate gets hotter with global warming, ice in the Arctic and Antarctica may start to melt. Sea levels will rise and many low lying places could be flooded.

Did you know?

Yes, I did. You know what I’m saying?

This is another did you know. I did not know this. Maybe I didn’t know it, let me tell you. Ships and boats float higher in salt water than they do on fresh water and that’s because the salt water is more dense than the fresh water. They got experiments for all this stuff over here. That’s just kind of, again, with build a library and you never know what you learned, right? That’s kind of what this was all about. Again, this is the Science Encyclopedia right there. Look forward to you guys reading a little bit more if you’re interested. I want to try some of these experiments. They’re base for kids, excuse me, but they look interesting to me.

Planet Earth Floods

All right, let’s go a little bit into … We’ll do one of these little biographies. Yeah, I should have picked underground worlds, but whatever. We got … This is Planet Earth Floods. Look at all that water. Let’s see, this is a time … Where is it? Sorry.

Time Life Books. This is when Time Life used to make lots of books. They have a lot of biographies. All right. Let’s see what we got. Excuse me. Floods That Come in a Flash. Is that the whole book? Yeah. Well, these chapters were pretty long. Right? Floods That Come in a Flash. 96.

What is this? What is it? 96. I keep getting … I love the ones with the pictures. Right? We get distracted. What are they doing over here? Floods That Come in a Flash. Look at them. They’re stuck in the … Look at that. They’re stuck in the middle of nowhere. That would be miserable. Look at it.

“A mother and child perch precariously on the roof of their submerged automobile as the waters from the flash floods swirl around them.” Yuba City, California, ’55. Trapped atop a car for seven hours. Do you even see the car? I don’t see the car at all, dude. That’s seven hours stuck like that. That would be … Not only would it be scary, that would be absolutely horrendously miserable.

It’s just showing us a little bit of damage. Is this? Yeah. Look, I think this is … This is it before, then a flash flood came. Right? And this is it right after the flash flood. It says nine members of the family … Goodness, gracious. That’s terrible. Nine people drowned in that flash flood. And look, the house doesn’t even … Look, the house … There’s nothing behind here.

Look, the house then was drug away. Wow. Look at this stuff. Right here, we got the severe thunderstorms. Yeah, okay. A severe thunderstorm starts to develop. Masses of low-lying, warm, humid air are sent whirling upward by the atmospheric disturbance and condense into a billowing cloud.

When the cloud rises to 50,000 feet, it is ascent and it is checked and a white, anvil-shaped cap appears, blown horizontally by prevailing winds. Rain begins to fall, producing downdrafts that eventually dissipate the cloud.

So, that right there is what creates severe thunderstorms. That’s crazy. Very interesting. Look at these pictures. This is North Dakota, 1970. How old is this book? Okay, so here we go. We got gauging … Are we still on the same chapter? What is all this stuff? No, no, no. We’re done. We’re out of there. You see, this is a … No. Are we? Could be.

No. We sure are not. It looks like a flash flood to me. Look at these pictures. Yeah. Look at that. That’s a flash flood. Wow. All right. So, this picture right here, which was a 100-year-old … What is it? What did I say? Fieldstone mill? I don’t know what that is, but whatever. On some river I can’t pronounce. This one right here … Had tons of explosive magnesium stored.

And the floodwaters triggered the whatever, and it made a violent chemical reaction and it exploded it. Making the people not being able to get close to take care of it, which that is super scary. Because if you think about it, all this water right there would be contaminated. Right? With probably poisonous water, chemical water. That’s crazy. That is crazy.

Let’s see if we got any more pictures. A little town that faced a torrent. Oh, man. Look at the water coming. Imagine that’s coming at you. What are you going to do? Oh, here’s some pictures. You see the … I guess this is a flash flood. Yeah, look at it. Kind of in the middle of it, and kind of straight in the middle. Middle of the night. See that … That’s what would be scary.

That would be like … This is sad. So, they were driving down the road, and the bridge came out on them. And then, the baby, the grandmother, and the mother, all three of them died. But again, man, at nighttime. That would be terrible. So, yeah. Flash flooding.

There … Honestly, I hear it all the time. I live in North Carolina, but I’ve never really … I mean, I’ve heard it my entire life. Flash flood warnings. And I’ve seen flash floods. Right? And they literally come out of nowhere. But I had no idea that they could be this destructive. That’s just crazy. Wow. That’s crazy. All right.
