Launch Report and Debrief Launch Time: 13:24, 5/19/14 Team Members Present: Tim Walsh Play-by-Play: Half throttle off launch pad, accelerate to 200 m/s. Decrease throttle to keep below 200m/s until at 6km. From there go full throttle. After fuel runs out, separate fuel tank from pod and parachute. When pod is 400m from ground, deploy parachute. After soft landing, recover vessel. Photographs: Photos to follow Time-of-Flight: Didn’t track, but ~00:03:00 Summary: Not many risks here, all in all a good flight. Keep it simple, stupid! Opportunities / Learnings: Simple is nice, keep it manageable. Strategies / Project Timeline: Let’s move on!! Going to go grab that 50km milestone! Milestone Awards Presented: 10km manned milestone, 20,000 in funds. Available Funds: 57,864. Lets do this!

The Physics of Poems (Or really, the poem of physics)
walsh416 posted a blog entry in Walsherific Blogging!
Physics is.. so gosh darn great I feel like it and I... are fate. With a Newton here, or a Pascal there, These SI units we love and share. Whenst look for a potential mate, All emotions to physics, they equate. If the air in the room feels perhaps electric, Just know that physics isn't eclectic. A standard mix of fun and function, Studying physics fills one with compunction. Alas, alack, it is time to go, I'll need to do work, that's fo' sho'. As Bernoulli said, just go with the flow. So shine like a lumen and simply glow. -
Lumberjacks are big dudes. Because they are more massive than the average human, they also weigh more. This bigger weight (or, more properly, increased gravitational force) means that the must do more work to travel the same distance. Since work is directly related to force in the direction of travel, much greater forces are required. As force the second derivative of kinetic energy and the first derivative of momentum, when one increases the rate of the others will as well. As seen in the diagrams below, lumberjacks mean business. So does Ryan Gosling.

Well, Michael Scott would be proud. We have finally considered all our paper and copier needs and determined that lined, microperforated notebook paper is the key. Microperforation is the strip of tiny holes punched in notebook paper somewhere between an eighth and half an inch from the spine, selectively weakening the paper to tensile forces parallel to the spine. Essentially, it's designed to let you tear out a piece of notebook paper without ripping it or otherwise destroying it. By perforating the paper, there are fewer contact points along the intended direction of tearing. This means that for a given tensile force, each little paper piece (differential of paper length? not sure that's a thing...) feels greater 'pressure.' Microperforation is a game of compromises. Perforate the paper too frequently along the intended line of tearing and it will simply rip out when a force is applied. Perforate it not frequently enough and it will be as if it isn't perforated at all. Make the holes too big and now your paper looks stupid. Too small and they are ineffective. And all sorts of other thrilling compromises. Woohoo.

Lately, it seems as if everyone and their mother has a "Lifeproof" case for their iPhone. Seriously. If my mom had an iPhone she would absolutely buy one of these. The logic behind it seems to be that the average life is wet, rough, and crazy (enough said on that subject...) and that one should always use protection. For your phone. C'mon, people. But how do they work? Typically, they contain a series of seals made of a relatively malleable type of rubber. When compressed and then held in place by clasps or screws, the rubber conforms to the other surfaces, forming a watertight seal. For those of you looking to waterproof anything homebrew style (you know, waterproof a sink or a cat or a little sister just for fun), the trick is in the type of rubber, the surface it's conforming to, and the way it is held in place. The rubber must be flexible enough to meet up with the surface, but not so flexible as to deform and let water in. The surface has to be flat and straight, something it's easy to seal against. And finally, the rubber must be kept under essentially as much pressure as possible to maintain a seal. So that's it!! Post pictures of any waterproofed cats/sisters in the comments below!

Ahh, sleep. Slumber. God's gift to mortals. Sleep is all about comfort. As many a mattress commercial has drilled into my head, not all mattresses are comfortable. There is a supposedly optimal point of squishiness and firmness and pillowness and sleepnumberness and weird-yoga-guy-meditating-on-a-mattress-for-no-apparent-reasonness. In short, different people like different mattresses. The generic want for a mattress, however, is relatively universal. This is due to the way gravity acts on the human body. Since we are not simply a point mass, gravity pulls on our entire body. When laying down, as if to sleep, this pulls us towards the ground. Due to the natural contours of the human body, the actual contact patch with a flat floor is relatively small, leading to high pressure areas (since pressure is inversely related to area, with a smaller area a greater pressure is produced). It is this pressure that is considered uncomfortable. A good mattress will conform to one's body, greatly increasing the size of the contact patch between human and bed. Speaking of beds and mattresses, hot damn one would be nice right about now...
