I'm a big fan of Lego. I wouldn't quite call myself an enthusiast, but I do enjoy a good build every once in a while. I remember when I was little I would always try to build these massive structures and would wonder why they would fall apart. Now I see that It's because of my awful engineering. I would create an immaculate creation with weak pivot points, allowing its natural torque to attack all of the little points I left unguarded, until eventually it would crumble. Or worse yet snap, sending Lego pieces everywhere. The Lego pieces will have fought so hard to remain in place, and once the connection is severed, all of that built up energy goes directly into sending little bricks flying all over the place for you to find months later when you're cleaning behind the couch even though you know for a fact that the Legos never actually left you room and how did they even end up down here... Anyway, here's a Lego particle accelerator...
Once when we lived in my old house, we had this nifty little blow-up pool. Basically, you inflate the top of the pool and fill it up so the air lifts up the sides of the pool. My mother always told me to stay away from the sides of the pool, but of course that’s exactly what I didn’t do. One summer me and some friends were all swimming in the pool together and I had the ingenious idea to lift myself up using the side of the pool. This wound up being a very bad idea. You see, as the side went down, some of the water started leaking over the side. This added more weight onto the side pushing it down even more, allowing more water to escape. This vicious cycle did have an end however, though not before traumatizing a poor, unsuspecting child. The force of all that water pouring out was so great, that it literally swept me off of my feet and dragged me down halfway across our backyard, finally stopping at some pine trees growing against our back fence. Although in small quantities water is relatively harmless, we must remember that combined, all that little force begins to add up, creating a tidal wave of destruction
I'm kinda a fan of super heroes, and one of my favorites is Batman. Not only is he an amazing detective, but he's the only powerless hero tough enough to be a founding member of the justice league, the most powerful collection of heroes in the DC universe. One of the things that makes him so great is his wide array of villains. There's one villain in particular who seems to defy the laws of physics, without having any real powers of his own. I'm talking about the immortal Ra's al Ghul. I say powerless in the sense that, besides his access to the Lazarus pit, he should not have any inhuman abilities. I say should because even with this, he still manages to perform some outrageous feats. One of which was displayed in the movie "The Son of Batman" where he had only his sword against an entire squadron of armed gunmen. This battle should easily go to the group of people with guns, but Ra's manages to actually deflect the bullets with his sword. A bullet travels at over 1000 meters per second, meaning that he would have to react within one ten thousandth of a second in order to move his sword fast enough to actually deflect the bullet.
There's another character in my book that has another interesting take on electric abilities. Her power is that she can produce both light and heat from within her body. This is a useful power for getting out of some sticky situations. When captured, she can heat herself up and melt through things like zip-ties or hand-cuffs. She can also light up dark areas when the team has to make a quick escape through some dark sewers. Although these powers don't sound very electric in origin, I assure you they are. McKenna's power comes from her ability to control the current and resistance in her body. By increasing both, she acts like the filament in a light-bulb or a space heater. Thinking like this it would make sense for her to also be able to manipulate her electric potential, expanding the range of her powers and allowing her to perform even more incredible feats.
Another cool character is one named Nichelle. Nichelle is sorta like a walking capacitor, but with more control. If she is near one of the other electric children, she can turn on her power, and start drawing it out of them. Apparently having the electricity forcibly drained out of you is kinda painful, because she has brought all the other kids to their knees in pain. This makes her very powerful, but only against the electric children, and she's not liked by any on either side and is tossed aside after she has outlived her usefulness to the company. This occurs after her altercation with the main character Michael. After freeing a small group of rebellious powered children, Michael stages a prison break which is put to a halt by Nichelle. But then, one of Mike's non-powered friends tells him to give her his power, and he does just that. Like I said before, Nichelle is a walking capacitor, and capacitors are notorious for having a capacitance, or maximum capacity. When Michael started feeding her his power, he overloaded the capacitor until she couldn't take it anymore and passed out.
Now I know what you're thinking, "Dude, is this another blog about Static Shock?" And the answer is no, it's not. This one is about a book, consisting of seventeen children with unique electricity based powers. The first I want to delve into is one I find rather interesting. One of the core main characters, Taylor, has a rather interesting ability. She can mess with bioelectricity. More specifically, she can stop the neural electrons for a moment. This creates a reaction similar to what is caused when someone tries to recover from not actually paying attention to what was going on and snaps out of it confusedly. She calls this "rebooting" them, and this basically grounds a person's brain for just long enough for them to forget what they were doing, such as a teacher yelling at her for passing notes, or a security company trying to kidnap her from her family and use her as a weapon to take over the world (hey, what kind of book did you expect me to read?) All in all, I'd say this is a useful skill to have.
Yup. He even electrifies the air, but only in special circumstances. After being captured in an airtight capsule, Static knew he only had a limited amount of time before he would pass out from lack of oxygen. His electric blasts were useless on the nonconducting glass, and he was running out of ideas, and air! That's when he had his brilliant idea. He could ionize the air. This would cause the particles to bounce around more, making the air expand. He continued this until the glass couldn't handle the pressure and exploded.
Sticking with our current hero, I'd like to go into one of his other abilities, namely his "static cling." This is also a power from early in the series after he caught his first bad guys. He needed to leave the crooks for the police but didn't want to have to wait around for them. His solution: stick them to the wall. He did this by creating a large amount of static electricity between their clothes and the huge metal warehouse wall. This held them there until the police could arrive, at which point he discharged them from the background before flying off on his little metal disc. Talking more in-depth about the static cling physicsally, this had to be a pretty strong magnetic force. It had to hold the clothes perpendicular to the force of gravity pulling down and I don't know if you've ever rubbed a cloth on metal, but it doesn't exactly have a high coefficient of friction. Therefore, all the upward force needed to counteract gravity would need to come from the static cling, making Static one strong hero.
There's this show I used to watch as a kid called Static Shock, about this kid who almost got caught up in a gang war but instead get super powers (great premise, right?). His basic skill set revolves around his ability to manipulate electricity, which I thought was fitting considering our current unit, and I think I can get a couple blog posts out of it. Anyway, one of the most memorable uses of his powers is his flying disk. Early on in the series, Static has to make a quick getaway and sees an old metal garbage can lid. He uses his powers to magnetize it and pulls it towards himself. He then proceeds to jump on it and fly away. This is explained in the show by him creating "imbalances in a self-generated electromagnetic field" that force the disc off the ground and allows him to fly. This also allows him to stay on the disc, even while upside-down. So you can bet that when I do inevitably receive the ability to manipulate electricity that I will undoubtedly be putting this to the test.
In my last work entry(not splash though), I forgot to say how I blame physics for me getting wet. I know the pizza cutter could be involve, but that's more my fault. The real problem is all of our bowls and ladles. I don't know why or how, but all of our round dishes have the perfect curvature to completely soak me every time I spray them. It doesn't matter which way i face them or what angle I shoot from, somehow it always manages to soak me. I know the materials have little to know friction, especially with water, so they don't steal much energy. any energy going in is retained coming out. This allows for the proper soakature of the washer(that's me). Then, the angle throughout the bowl is ideal for altering direction, even defying the very laws of physics, just to get me wet. That is not okay, and I fully expect the physics police to go and arrest those bowls while the case holds water, and the ladles before they stir up any more trouble. Until next time, I'm too lazy to look up another goodbye in another language so ta ta for now
This title might sound fun, but I can assure you it is not. If you are currently following my snapchat story, you know about the flattop debacle at work. For all you normal people, I'll give a quick recap. Today I had to clean the flat top grill at work. This is done by pouring on pickle juice vinegar on the grill and wiping it off with this brick thing. The trouble was that I had to clean all the corners, and our flattop has these little walls around the cooking area, I assume only for the purpose of causing me pain. So I was using this brick to clean off the stove top, and I decided to go after the corner, brick held firmly in my hands, weighed down significantly by my awesome muscles. The only problem was all the pickle juice left on the stove, and as the space between the wall and the brick grew shorter, the vinegar had to go somewhere. The rate of area loss for the liquid was too grate (if only this story were cheesier...) for it to pour out the front, and it had to push in other directions. Namely up and onto my arm. Can I tell you what's not fun? having burning hot vinegar on your arm. That's not fun. It's pretty much the opposite of fun. Anyway, I blame physics for all my pain and suffering tonight, so until next time, kwaheri
Godspeed - an expression of good wishes to a person starting a journey.
But what is godspeed exactly? Why did this term come about? I'm assuming that it would originate with wishing someone a speedy journey, or a rapid completion of some task... much like this one... But I like to think that this phrase sort of evolved from people trying to one up each other in good wishes. Specifically I'm imagining two people trying to prove that they're the better man, with each response being more angry than the last.
Man 1: "May you have a good journey"
Man 2: "May you have a speedy journey"
1: "May your velocity always point towards your goal"
2: "May your force guide you their, whichever way it must push"
1: "May your journey require little force multiplied by the distance traveled"
2: "May yours be friction-less"
1: "May yours be completed at c, the speed of light"
2: "May yours be completed within the nanosecond"
3: "May both of your journeys be completed with a speed synonymous with that of God"
(1 and 2 lower their heads in shame upon realizing the delinquency of their actions)
1 (whispers): "Speed of Hermes"
2 (also whispers): "Speed of God"
3 (Whispers in triumph): "Godspeed"
(1 and 2 now admit defeat at the hand, or more the mouth of, their better)
Yeah... so this is what just happened in my head... sorry you had to see that. Back to the point I was going to make, godspeed is a speed which the human mind can barely begin to fathom, much less achieve. Our current laws of physics prevent any object from traveling faster than the speed of light. Godspeed would be millions of times faster than that. It is the speed traveled by a being that exists outside of time, a factor that is kind of necessary when calculating speed. Maybe attaining this speed would be the answer to the question of time travel. Move so fast that you move right out of time, then traipse along to whatever time you want, and slow back down. Maybe say " 'sup " to God on the way too, it is his speed after all.
Well, until next time, Kol Tuv
Now I know you all think this is going to be me continuing on the same topic, but calculating the work. Well I'm not. This is a story, all about how, I acted like a physics nerd at work. So when I'm actually washing the dishes, I like to amuse myself with physics. Either that or blame it for me getting soaked. For entertainment purposes, I wash the pizza cutter. This brings my childlike mind joy because the water, traveling at a tangential velocity, strikes the blade, pushing it in the same direction. But alas, the poor blade is restrained by a foul axle. This little peg stops the blade from travelling freely, and allows only circular motion. The tangential velocity of the water has an angular momentum with respect to the axle, and this momentum is then given to the blade. The water, wanting desperately to be with the slicer clings on for dear life, yet he is not strong enough. Though his course be altered, nothing could stop the motion of the ocean-spraying out over the kitchen floor. He flew through the air, never to meet his pizza slicer again... So basically it makes it spin really fast and the water sprays out in a really cool disk motion, it's tons of fun. R8 10/10 would do again. Anyway, until next time, yasoo.
Well, continuing on from my last blog, I wonder exactly how much it would hurt to fall that far. Lets find out! This would be an approximate 30 meter drop, plus the height gained from the initial liftoff, which is... still approximately 30 meters, looks like my pride is going down too look at that. Anyway, a thirty meter free-fall with a ten meter per second acceleration gets you to a velocity of 31.6 meters per second. So, if I were to be a complete and utter moron, I would simply stand straight like a board and the ground would decelerate me rather quickly, lets say about .3 seconds. 31.6 m/s divided by .3 seconds is a deceleration of 105.4 m/s2. This multiplied by my mass of 72.5kg leads to a whopping seven thousand six hundred and forty two newtons of force. This sounds painful to say the least. But what about if I could extend that time by absorbing as much of the force as possible, namely doing a "tuck and roll" which have quotes because I decided they should have quotes so there. This highly sophisticated procedure would require me to tuck my legs upon impact with the ground, and then roll into a ball before rolling away. The main 'impact' of this would be to extend the time of deceleration as much as possible. Ok so i just ran out into the hallway and simulated this to be about one second. Not exactly what I was hoping for but still, it's progress. Now the 31.6 m/s is divided by 1 second, for a deceleration of... 31.6 m/s2. This resulting force is two thousand two hundred and ninety-one newtons. Still not exactly the ideal scenario, but I guess I won't be preforming any of my own stunts any time soon. Until next time, sayonara.
For this blog, I decided it would be fun to try and figure out if I could realistically jump from the roof of IHS to Dake. Typing that out I realize how stupid that sounds but I've already started so here goes. IHS is one storey taller than Dake, which is approximately 10 meters. The distance between them is about 12 meters, approximated by 17 paces to walk between the two. (I'll double check these figures best I can and come back with an edit soon.) The average person can run ten to fifteen miles per hour at their prime. Assuming I'm on the lower end of that spectrum, that's about four and a half meters per second. If I were to jump at the optimal forty-five degree angle, that'd be about three meters per second vertically, as well as horizontally. This liftoff speed over the ten meter drop leads to a 1.7 second jump, which would get me a distance of 5.2 meters away from the high school, and still 6.8 meters from my destination. Thusly, my new destination would be the ground. And I'm assuming that would hurt... a lot. Well thank you for joining me on this segment of Dash My Dreams of Being a Spy, until next time, arrivederci. (Thank you google)
So I work and this restaurant where we do this thing and cook food and then we give it to people and they eat it and enjoy it and stuff. So we have this one oven that is basically just a conveyor belt with a giant heater blasting down warmth to cook food. And I know it's blasting because the sound is almost deafening. And this thing is basically running constantly, to the point where you just get used to it and forget that it's on, like if you always hear traffic outside of your window, but only notice it when there aren't any cars. But anyway, we were having a slow day and I was hanging out in the kitchen, trying to get everything wrapped up so that when we did the final clean up that night, it would go quickly. At one point I was walking across the kitchen and I looked at the conveyor belt thingy to see if it was on. It appeared to me that the belt wasn't moving, so I assumed it was not. But then, as I stopped on the other side, I realized that I was wrong. The machine had indeed been running, but since I was walking at the same pace, it appeared to me as though it was not. this is a prime example of relative motion affecting real life.
I'm going to assume that you guys watch TV and have seen that Tic-Tac commercial. You know, the one where the Tic-Tac is a meteor they see through a telescope? Well for some reason, the physics of that commercial irks the snot out of me. First of all, we look through the telescope and see the Tic-Tac flying left across the screen. It is presumably in space, attaining a high enough velocity that the air resistance peels back a layer of coating. But then, it just hits the telescope right on the lens and bounces off. This is wrong for two reasons. One, if we looked through the telescope and saw something flying to the side, the only way for it to change course that much would be for a force consistently pulling it towards the telescope, but the background stars move, showing a change in perspective. GET YOUR RELATIVE MOTION RIGHT PEOPLE! The other thing that bothers me is that this little mint has achieved a breakneck velocity, enough to EMIT LIGHT, and then it just plops to the ground after hitting the telescope. That's not what would happen! It would act like a bullet, breaking right through the telescope! If you want to make a commercial, get it right gosh darn it. So basically, this is what physics has done to me. This is the sort of thing that bothers me now. Thank you physics.
So yesterday at BE, we were doing this thing to show our appreciation to the teams that make us breakfast every Saturday and met in a different room than usual. This meant that we had to set up with different sound equipment than we were used to. As we ate, the system was used for some background music, but then the playlist ran out and the board started acting up. It started to send a high pitched sound out through the speakers. Obviously, this sound was quite annoying, and I began to wonder why exactly my dad (who normally runs the sound system) wasn't doing anything to fix it. My sister was visiting from college, so she went up and asked him if he was going to do anything about the sound, to which he replied, "what sound?" This noise was at such a high frequency that my dad couldn't hear it, and thus didn't know anything was wrong. A young, healthy human can hear sounds from 20 Hz to 20,00 Hz. This range deteriorates the older a person gets, explaining my dad's sudden lack of desire to fix the sound. He didn't hear anything wrong, so he did't go to fix it meaning that I had to go try and figure out what was wrong. I couldn't, so i just shut it off.
Now that I've reached the last blog for this quarter, I thought I'd take it full circle back to music. Specifically the drum set. Drums are known for being loud and helping other members in a band keep the beat of a song. This is due to how they are built. Let's talk specifically about the bass drum. This is the largest drum, seen on the bottom of the drum kit and normally played with a foot pedal. The reason that it's the biggest drum is so that it can make those loud, deep sounds. The foot pedal strikes the skin of the drum, causing it to vibrate. This vibration sends the sound waves out through the drum, where they bounce around the inside of the drum. Having such a wide radius and depth, the drum allows the sound to reverberate within the drum before heading out to greet the audience's ears. This keeps it at a low frequency and allows the sound to build up and strengthen, becoming louder and reaching farther before dissipating.
I went to the RMSC recently and found some really cool stuff upstairs. One thing in particular that caught my eye was a water/strobe light display. The way it was set up, there was a window to look through and two dials. one to control the speed of the vibrating hose, and the other to control the speed of the strobe light. When both were aligned just right, the water didn't appear to be moving at all. This was because the speed that the hose was vibrating was the same as the strobe light was blinking, so the light only reflected off the water after that specific time, at which point it was in the same spot as the wave before it had been. These two changes were moving in the same frequency, making one cool interactive display.
Since someone brought up superpowers, I thought i would talk bout one myself. One power which was actually granted to many heroes after their initial creation is super flight. From Superman to Thor, comic writers had many other ways to make it seem as though the heroes were flying across the sky, while still limiting their power. Originally Superman was not able to fly, but was "faster than a speeding bullet. More powerful than a locomotive. Able to leap tall buildings in a single bound." That's right, leap. He couldn't fly, his powers came from his body basically reacting to the sun like it was steroids made specifically for him. All he had was super strength and speed, which contributed to many other "powers" and led to him gaining many iconic abilities. He appeared to fly because of his super strong legs. He could apply such a downward force when he jumped that he could propel himself up over twenty stories high. Thor got his "flight" from a slightly different method. When using his strength, he swung his hammer around so fast, that when he let go for a split second, the momentum in the hammer would be enough to pull him up off the ground and make him appear as if he was flying. This would be due to the change of angular momentum into linear momentum of his hammer, which has an approximate mass of 6.8*10^14 kilograms. Thor's mass of 291 kilograms is inconsequential when dealing with such a large mass, and thus his hammer would maintain it's momentum, making it appear as if he could fly.
Every Saturday, my family and I go to a children's ministry in the city called Bethel Express. I help whenever I'm needed, but my parents do a lot, which at one point included driving a sixteen passenger van around the city to pick up a ton of kids. One winter, my dad decides it would be fun to take this van full of kids and start driving in circles on the empty(thankfully) and icy parking lot. Driving in this motion caused the van to start sliding on the snow and we started doing doughnuts in the parking lot. "Why did the van start sliding in circles?" I'm glad you asked. This is in part due to the lowered coefficient of friction between the tires and snow, as opposed to the tires and pavement. This only makes it easier though. What is it that causes the van to want to spin around in huge circles? This is because of centripetal force, or lack thereof. The frictional force would normally be the one pulling the circling van towards the center of the circle, but with that force depleted, the tires just continue sliding to the side, pushed by the still low force of the tires spinning on snow. Needless to say this was a highly entertaining experience, and one that I will not soon forget.
This next post happened a little while ago, but I'm bringing it up now because it's kinda funny. My aunt was at the pet store with my mom, and as she was walking around the store, she suddenly lost her balance. This was due to the fact that she had stepped on a goldfish. Now goldfish, along with most other fish, are notoriously wet and slippery. This is due to the lack of friction between them and other surfaces because of the layers of water and whatever else they're covered in. This lack of friction caused my aunt's foot to continue moving forward when she expected it to stop on the ground, and thus the rest of her was quickly brought down to earth. Luckily she was fine, but this does make a great story, especially when you can throw some Phyzx in there.
Continuing on with my family and wheels falling off of vehicles, I turn to a tale told to me by my mother not too many moons ago. It begins with her, driving in her car. I don't recall many of the details, but she was on the expressway, or was it the parkway? I'm going to go with driveway. So my mom was doing about 65 on the driveway when all of a sudden out of the corner of her eye she spotted it (Shia LaBouf) (this is completely off topic and has nothing to do with the story but if you get the reference joke I applaud you) Anyway... She was driving along when she saw something speeding ahead of her. It was indeed her wheel. Now just to be clear, this was not just the rubber tire that fell off, this was the entire flippin' wheel. All those metal bits that connect the rubber to the car suddenly stopped connecting the rubber to the car. The wheel went careening off toward the side of the driveway, and my mother veered across a lane or two and managed to safely stop the vehicle without any serious damage being done to her. This is an interesting physics observation because, after the initial separation from the car which I am still unaware of the cause, the wheel went faster than the car, even though it no longer had any force on it pushing it forward. This can be linked to many things, the kinetic energy of the system (including rotational), the momentum of the system, friction occurring in the car that no longer constrains the wheel, allowing it to finally be free of the oppressive weight of the tyrannical car. Any of these, and more likely all of them combined, are the cause if this random observation.
Last year, as many of you may recall, we took some big tests in the gym that took up a bunch of time in the morning. Preceding one of said tests, I was at home, running late for school. In my defense, my mother (who normally drove me to school) had just departed for Greece with my sister and not me even though the initial plan was for me to go and I am definitely not bitter or anything, but I digress. Anyway, I was running late for the English exam and hopped on my handy-dandy bike to pedal my way to school. Now I'm sure you're thinking, "He's bringing up all this backstory for the physics of riding a bike?" but you would be wrong dear reader, for this was no ordinary bike ride. Seeing as I was running late, I was pedaling a bit faster than I normally would on my way to school, which was evidently not my best idea. For you see, the night before it had rained, and there were still puddles lining my path from home to school. Now I know what you're assuming happens next, "his bike is just going to skid on the wet pavement" but it is so much better than that. As I was riding up Titus, there was a puddle blocking my way back up onto the sidewalk. Not wanting to get myself all wet, I decided to lift the front tire of my bike over the puddle just long enough to clear the puddle before continuing on to school. The only problem was my front tire wasn't having that, and decided to remain on the ground, while the fork of the bike rose up in agreement with the force of me pulling back on the handles. This was the main source of my dilemma because I was not applying a constant force, I had only created an impulse, which was not enough to counter gravity long enough for me to come up with a way to avert disaster. Thus, as the saying goes, what goes up, must come down, and down I did go. Thankfully, I walked away with only a couple scratches, and still managed to make it to school on time for the test.
