First day of classes {Spencer} 9/30/15

Hey all! I'm highlighting an interesting day in the UW life--in this case, the first day of classes--from my journal at spencerpetersblog.blogspot.com.

1. 9/30/15

a. First day of classes! Hopped out of bed at 9:20, took a shower, ate breakfast, and meandered down to my 10:30 class (Math 334, 2^nd year accelerated calculus, though our professor . Showed up 15 minutes early, met Johan and some other classmates. Our professor James Morrow is awesome—seems like a guy who really appreciates and has fun with math. I was worried he would be all competitive and assessment-focused—not at all! Very cool fellow. We talked a bit about the foundations that are going to be involved, about the different ways of approaching the question, “what is a real number” and some philosophy of math. A bit about Rⁿ (often thought of as n-diml space) as a set of all functions mapping {1, 2, …, n} -> R.

b. Had lunch with Issa at the 8. Talked about our summers, people we knew.

c. Headed to 332, Data Structures! A bit early, registered a ton of familiar CS faces before our prof Adam Blank had a chance to overflow with teaching enthusiasm. What a boss! Awesomely designed lecture. He had one amazing example where by cleverly using a tree, a simple object designed to store, update, and sum over a list of numbers became much faster (O(log n) in both sum and update vs O(n)/O(1) tradeoff) He shared my flaw, though, speaking really fast and causing a bit of confusion (to my mind at least).

d. Then to 312, Theory of Computing 2, probability and statistics! Another cool prof, Martin Tompa. He’s really obsessed with this Austrian trick-taking game called Schnapsen (sounds fun). We’re going to do homework problems about Schnapsen, play informal Schnapsen tournaments. Same familiar CSE faces. I’m really starting to feel like I’m part of a coherent class of students.

e. Aaand… my TA meeting. Turns out I don’t get to teach a section (grad students, previous TAs, and women all get priority over me, which makes sense). Sad face. But I do get flexible hours, and office hours. Happy face! Much to learn to get settled into the position.

f. Headed over to SPS in hopes of meeting other members who’d been corresponding about a meeting at 3:30. They were there! Talked to Frank, figured out stuff to say at announcement Friday. Said hi to Davin, short-bearded Jacob, long-bearded Jacob. sbJacob showed me how to make posters and use the Physics print room. Printed off lots of lunchbox posters to pin all around campus.

g. Met Jasdeep and played basketball. It was fun. Just a relaxing dude to be around. We played some 1-on-1, and I started crushing him, but then he upped his intensity level and we were pretty even.

h. Took a short run to round out the exercise in the beautiful reserve south of Haggett, returned, showered, and hit the 8 just in time to meet Winnie, the physics and philosophy student from linear algebra last year. We ate outside and caught up.

i. Returned to Haggett, baked some cookies to distribute in the hallway. Met some 5^th floor denizens, including an extroverted and sharp business dude named Erin trying to cook some pasta. Returned to 8^th floor to distribute the cookies, when…

j. 3 girls burst into my room, ostensibly having followed me from the fifth floor. They introduced themselves in a very forward manner as cookie lovers. I offered them some cookies and water from the fridge. I had to distribute the cookies while they were still hot, and trying not to be impolite, I invited Elanna, Grace, and Gracen to help. I assumed they would just hold cookies. But they immediately marched out into the hallway and started banging on doors, loudly calling the names of the inhabitants. I couldn’t stop them in a socially acceptable manner, so I ran behind trying to come up with a narrative of why I had baked the cookies and these goofballs were distributing them. Destroyed my plan of standing in the doorway and chatting for 5min with each cookie recipient. But it’s a good story. After the last of the cookies were woefully distributed, they went to the lounge and I Skyped mom and dad. The internet was atrocious and we gave up after 15 minutes. Then I did email (another person asking for physics tutoring!), lots of reading for classes, wrote this log, and hit the sack.

Summer Summary! {Monica}

Our summer here in the PNW was absolutely wonderful. We had tons of sun, lots of warm weather, and very little rain. That last one did become a bit of a problem as fires sprung up all over the state, including, at one point, four in our county alone. But for us in Bellingham, the fires didn’t cause much damage, and we have really just enjoyed a terrific summer.

Homeschool Academy

When Spencer came home for Memorial Day weekend in May, we spent an afternoon together catching up and hanging out. He brought up an idea that he had had, a sort of summer school for homeschooled students, by homeschooled students. Us older kids could each teach some things we are studying and know a lot about, and the younger kids could learn in a low pressure environment. I thought it was an awesome idea, and we brainstormed a bit before Spencer went back to UW.

A few weeks later, when Spencer came home for the summer, he, Grace, and I started seriously discussing how to make this work. We decided who would teach what, we came up with a schedule, we polled our potential students to gauge interest, and we recruited Henry, another homeschooler, to teach as well.

The week after the 4^th of July, we started our 7 week Homeschool Academy! Some things went great, others were a learning experience of what not to do next time, but in the end it was all a success. I taught a one off Literary Analysis class that was super fun, an Irish dance class that was way more popular than I expected, and Grace and I co-taught a Geology class.

It’s hard to say what will happen next year, but if we do this again, I have lots of ideas of things we could do differently to make it even better, and if we don’t do it again, we had a lot of fun this year!

Dancing

This felt like the summer of Irish dance. We had summer dance classes for six weeks. Having two hours of class in the summer sometimes feels like too much, but I also really love it. We performed at the Bellingham Highland Games in early June, the Whidbey Island Highland Games in early August, with the band Celtic Roots at Birch Bay State Park in the end of August, and then at Boundary Bay Brewery with the band Gallowglass a few days later.

Our Irish performances are always small and pretty casual. I’ve been in a few big dance productions by Northwest Ballet Theater, and they feel so different. Dancing in Rhyth McFeet (that’s our performance group) is a lot of fun, but still low pressure.

At the moment, it’s hard to say what will happen with Irish dancing for me in the future. Some recent events and announcements have made ithard for me to predict anything about my future with dance, but whatever does happen, this last year of dancing was pretty darn awesome.

Camping

In August, some families from our homeschool group went camping in Bend, OR. Camping in Bend is awesome, and this year was a lot of fun. Here are some of my highlights from the trip (as previously posted on my other blog):

1. Late night campfire philosophical discussions with Ted and Spencer. Staying up til 12:30 talking was one of my favorite parts of the trip.

2. THE RESISTANCE. This was a game we played a lot on this trip. In it, there are randomly selected 'spies' and 'resistance members.' The spies know who the other spies are, but the resistance have no idea about anyone. The resistance wants to succeed 3 of 5 mission to win, and the spies was to fail 3 of 5. The rest of the game mechanics don't need to be explained here, but seriously, this game is awesome and you should play it. We played this a ton, and learned that some of us are much better at lying than others.

3. Rafting down the Deschutes River. The river is pretty mild and you can hike up about a mile and the float all the way down to the campground.

4. Exploring the river! On our last full day there, a group of us went about two miles farther than usual. We didn't know what to expect but what we found was a lot of beautiful scenery, some pretty deep water, a few mild rapids, and a little island full of wildflowers. It was awesome.

5. Waking up to the sound of the younger kids around the fire. There was a group of about four kids who were always up early, and it was not uncommon to wake up to the sounds of them talking about Lord of the Rings, or Monty Python, or who knows what else.

6. Playing mafia. I love this game, and it's a lot of fun to play it around the campfire in the dark. We had one game where the mafia won (which isn't that common), and one where the mafia was lynched but after a pretty long, interesting game. We also had some great storytellers, which made everything more fun.

7. Listening to podcasts in the car. We spent between 16 plus hours in the car on the this trip, and I spent a lot of it listening to old episodes of the Nerdist podcast, plus the new Hello Internet.

Disaster Strikes!

Less than a week after returning from camping, we noticed mold growing in our basement along one wall. The next day, further investigation proved that it was on the other side of the wall as well. A few days later, it was discovered that a pipe in the wall was leaking water, causing the damage. We had a water restoration guy out to clean the carpet, replace the pad, and haul away some of the danaged furniture. We’re still waiting for someone to come out and put the drywall back in.

I lost two book shelves, which were against the spot on the wall that sustained the damage, as well as all the books on the bottom shelves, which had a lot of water and mold damage.

The last weekend of August, Western Washington was hit by a massive wind storm. It knocked out power for much of the western half of the state, and caused a ton of damage. We lost power for about 12 hours total, and we had a tree fall on out house. It didn’t cause any structural damage, just a few scrapes, but it did take up our entire yard for a few weeks until we managed to get it hauled away.

My friend Lydia didn’t get her power back for nearly three days, so she ended up staying with us for two nights.

And on into the future...

As of writing this, school started nearly a week ago. I am thinking this is going to be a good year, and I have high hopes for this quarter. Next week, look for a post from me about the first few weeks of school.

How to Make a Boffer

Today I’ll be making a short sword, but this tutorial contains the information needed to make all sorts of different boffers.

Link to this tutorial as a Google Doc

Materials

You’ll need ½” PVC, Schedule 40, rated at least 480 PSI:

Plus pipe insulation, internal diameter ¾”, foam thickness at least ⅜”. You will also need ½” pipe insulation for the blade.

#variation #longerBoffer: For boffers 3’ or longer, you’ll use ¾” pipe and 1” pipe insulation, with ¾” pipe insulation for the blade.

You’ll also need ordinary duct tape, and optionally, two rolls of colored duct tape and electrical tape.

Now let’s get started! Here’s a big-picture overview of the boffer-making, or smithing, process:

And here’s a more detailed description of the recipe we’ll follow:

Cutting the Pipe

You can cut the PVC with an ordinary hacksaw or a fancy pipe cutter. Your boffer will be about 4” longer than the length of pipe that you cut, due to padding at the ends. Remember, if you want a boffer longer than 3’, use ¾” pipe!

Once the length of pipe is cut, the next step is to cap the sharp ends.

Mushroom Cap 1

First we’ll make a reinforced mushroom cap to protect the delicate foam padding from the ravages of the pipe. We first cut a piece of foam, overhanging the pipe by about ⅛” on either end:

Now we cut the stem of the mushroom cap. Starting at the seamed end of the insulation, cut about halfway up the foam on either side to make a stem whose width is the inside diameter of the pipe.

Now wrap the stem with a piece of tape ripped in half lengthwise (a half-strip):

Next, reinforce the inside corners with half-strips:

Next, prepare some half-strips like this. These will affix the mushroom cap to the pipe.

Squish the stem of the mushroom cap into the pipe. This might require some twisting.

The next part is a bit tricky--you might want more than two hands. Lay a medium half-strip across the long top edge of the mushroom cap. Using your thumb, press down on the top of the cap, hard.

Next, while keeping your thumb pressed firmly on top, fold the edges of the cap that the half-strip lays across, down firmly to the pipe, and tape them down. The idea here is to cover the sharp edges of the pipe with foam and tape. When these edges are down, use a short half-strip to fix the medium half-strip in place (the medium half-strip should be under a lot of tension).

Repeat the process, but this time place the medium piece of tape at 90 degrees to the last one. You’re taping down the other two edges of the mushroom cap. It should look like this:

Or this, but maybe not so tilted :)

Now you’re done. Whew! But wait, there are still two medium and two short half-strips left! These are for the pesky diagonals. Repeat the medium-short process two more times at 45s to your previous half-strips to bring the diagonals into line. Now things should look like this:

Finally, wrap the long pieces around the mushroom cap. Apply lots of pressure. The first piece is to push in all the foam that isn’t folded flat to the pipe’s edges. The second piece is lower down, and it reinforces the connection between the top of the mushroom cap, and the pipe.

The mushroom cap ends up looking like this:

Core Layer

The next step is to attach the core padding. First we mark the pommel and handle of the boffer, so that we know where the core shouldn’t go. Use your hand to mark the handle, and leave about 3” on the non-capped side of the pipe for the pommel. #variation #longerBoffer: If you’re making a longer boffer, you might want to consider a longer handle. I recommend 3 hands worth of handle for a longsword (3’-4.5’) and 5 hands of handle for a greatsword (4.5’ to 6’). Anything longer than 6’ will a) be very unwieldy b) require 1” PVC.

Next, we make double-sided tape to attach the core to the pipe. Hang a strip of duct tape from a rafter or window alcove:

Fold the edges in on themselves by thirds:

Continue this process, tucking right under left, until the entire strip is double-sided. Then wrap it around your boffer, starting at the handle mark. Try to avoid touching the entire strip--oil from your fingers weakens the adhesive. Instead, hold the double-sided tape far from the boffer and rotate the boffer to wrap the tape.

Next, cut your core foam padding. Cut it about 2” longer than the core area on the pipe that you just taped:

Attach the foam from the base.

Once the foam is around the pipe, reach inside the edges of the pipe and pull to tighten the gap in-between the edges. There may still be a gap at the top, where the mushroom cap is.

Don’t try to overstretch the foam to fill this gap. Instead, cut a piece of foam and lay it in:

Tape the resulting seam, and you’re good to go.

Compression Tip

We want our tip to be squishy. So we need a compression tip. We make this much like a mushroom cap. This time, the initial piece of foam we cut is as wide as the core layer’s diameter:

Again, we cut a stem, this time as wide as the inside diameter of the core layer foam. We want a tight fit, but not so tight that it distends the core layer foam into an oval shape.

And again, we wrap the step and reinforce the diagonals with half-strips:

We cut the core layer so that when the compression tip’s stem is inserted into the core layer fully, the bottom of the stem just touches the top of the mushroom cap. This way the tip doesn’t have room to bend from side to side when you’re stabbing. Note: the height of the mushroom cap stem is much less than 2”. I just told you to leave 2” earlier so that you’d leave 1”, not ½”.

Blade Layer

Our boffer is gonna be realistic! At least, it’s going to have a blade (“sharp”) edge and a flat (“dull”) edge. To make the blade layer, open the seam of a tube of ½” pipe insulation and cut it in half lengthwise (make a cut 180 degrees from the seam). I recommend making a few cuts, then checking if the two halves of insulation are roughly equal, then making a few cuts, then checking, and so on.

You’ll end up with this:

Normally, blades on swords only go one direction. But if we only did that, the tip could then wiggle in the perpendicular direction. So we use a small piece of blade to reinforce the tip in the perpendicular direction. Note that the blade folds, concave side down, over the curved edge of the compression tip, and that it is long enough to reach down to the place where the pipe is, under the blade layer.

The real blade simply crosses over the reinforcing blade. Attach it lightly with 4 strips of tape: 2 on each side, one for the base and one for the tip.

Pommel

#variation: If you want two blades, a double-sided sword, you can totally do that! Just ignore the rest of section Pommel. Instead, repeat all the previous steps, but on this side of the pipe.

You already know most of the recipe for attaching the pommel. First, you make another mushroom cap, exactly like the first, on the other end of the pipe. I know, it’s a pain...

Then you attach another piece of core insulation with sticky tape, exactly as you did before:

You fill in the gap with a custom-fitting piece of foam and tape the seam, like you did before:

Now things get different! Please, don’t be alarmed. We add a second core layer around the first. You can use ¾” insulation or 1” insulation for this.

Fill the (bigger) gap with another custom piece of foam and tape the seams:

Protective (and Colorful) Taping

Finally, let’s add a protective layer of tape on the exterior of our boffer! First we’ll do the flat, then the blade, in two different colors.

General rules while taping: Push the tape into grooves such as the one between the blade and the core layer, so that it lies flat everywhere. Then stretch the tape lightly to cover other areas. To tape the flat, first cover the bulge created by the reinforcing half-blade. Push the tape into the crevasse between the half-blade and the core, don’t stretch the tape over it:

Now tape the grooves between the blade and the core. Angle the tape strips as I do to reflect the fact that the boffer gets thicker from base to tip:

Repeat on the other side of the boffer (the other flat).

Now for the blade:

I recommend pressing the center of the tape down first, then smoothing to the edges. Now the tip (you can do this with one single piece of tape, but it’s harder).
