  1. As of last week, I upgraded from a cracked, partially missing screen on my Iphone 5c to the Iphone 6s. I was super excited to actually read my screen!! When I was at the store, I was strongly advised (probably from the looks of my old phone) to purchase a glass screen protector. The salesman said the glass was designed to take all the force if one were to drop their phone. He said the glass was similar to that of what the military uses (for what, I do not know). I am curious what properties of glass alter it's durability. Or other questions come to mind as well: if any glass is layered on top of the phone, will it protect it just as well? I also wonder how the force protects the actual screen from cracking. I hope the screen does it's job because with my track record, I'll have my phone shattered in a few months. On the plus side, even though the screen costed me $40, there is a lifetime warranty!
  2. Ever since I was a kid, my mother had always said "It's snot freezing cold outside!!" I've had a cold and a runny nose for the past of I don't know...eight weeks or so. Despite the late onset of winter temperatures, I have yet to experience "snot freezing cold" temperatures. I have had my share of freezing hair days but never have I ever experienced snot freezing. Now that I'm typing this, i realize this may be a little disgusting blog post........ Anyways, I say we shall calculate the freezing point of snot:) To do so, one should not be afraid to get their hands dirty. Also, I don't think getting a jar filled with snot would be realistic considering is it inside our noses. SO we would need a LOT of sick people. Good thing it's that time of year!! For my prediction, I think the freezing point would be every close to that of water but lower because of the mixture. It would be a little messy to see if I am wrong or right though...

  4. Over Christmas break, Mythbusters was running a marathon. I went to bed every night watching Mythbusters and woke up to watching it as well. I've always been really interested in the show and thought a lot of the myths were pretty cool. One that I found hard to believe and depressing is the myth: " Can lighting a fire in the fireplace with a chimney make the rest of the house colder?" They found that this myth was actually true. I said that this is quite depressing because personally, I hate being cold. Although truthfully, I never really noticed the drop in temperature because if my Dad makes a fire, I sit right in front of it and am known to melt/burn my clothing. Like me, I bet a lot of people find it hard to believe that a fire actually makes the house cooler. They say it is because so much heat escapes from the chimney, leaving the house cooler. It is said that a fireplace is one of the most inefficient heating devices out there because the hottest air the fire creates, goes immediately upward and out the chimney. So I guess it would be smarter for us to cover up Santa Claus' entrance and look for more efficient alternatives in making our homes nice and toasty.,

    flames

    I found a lighter one day and lit it and thought to myself, "why do flames have the shape they do?" I hypothesized maybe it was similar to water-the surface tension that allows one to lay a needle across the water. However, what I found was actually quite interesting. The picture attached shows what a flame looks like when gravity is present (left) and when it is not present (right). Buoyancy- a concept I wish to become more familiar with in the future- is a result from gravity. Why does the flame become the shape of a teardrop? These are the reasons I found: The products from the combustion that creates the flame go out due to buoyancy while oxygen is drawn in towards the flame. Solid particles are convected upward to create the yellow tip of the flame. Finally, to overcome heat loss, the flame migrates in towards the wick. Whereas if we compare the flame where gravity is absent, the flame creates a spherical shape because there is no "up" or "down". There is also a lack of oxygen which leads to lack of "soot" to be convected upward and a lower temperature. The loss of temperature also results in the flame to migrate away from the wick. I thought this was actually pretty neat! I really want to learn more about flames and specifically buoyancy as well.
  6. On the bright side, I wasn't the one behind the wheel when this happened. I had just finished rehearsal for the musical one Saturday morning (well, technically afternoon) and offered up the idea to my friend Jojo to go out to breakfast. He loved the idea and was even more willing when I said I would treat the both of us. As I got into the car, we were already off to a not-so-great start...Jojo had some difficulty changing the gear into reverse. After some "love taps" to the car, Jojo finally reversed out of the parking lot and we made our way towards East Ridge Family Diner. The roads were covered in slush, ice and snow. We came to a stop at the intersection of East Ridge Rd and Hudson Ave where we were in the left turning lane. Finally, the green arrow signaled us to proceed with the left turn. Jojo pressed on the gas and began turning the wheel. There were a few cars and trucks in the left turning lane on East Ridge Rd where we were coming up to. As Jojo released the steering wheel to allow it to glide back forward, the wheel had other plans in mind. We both quickly noticed the car still turning left heading right for the truck in the left turning lane. Jojo slammed on the brakes-which did a whole lot of nothing- and we screamed for our lives knowing what was to come next. Jojo relentlessly steered right but realized Newton's first law in action: an object in motion will stay in motion. Not only were Jojo and I sure that we were going to nail the truck, the driver of the truck looked to be on the same page as us with his jaw dropped and his eyes bugging out of his head. Miraculously, the car had won over the snow's resistance and we missed the truck by INCHES. Moral of the story: Jojo should seriously invest in some snow tires which are designed to grip the surface better and decrease the likelihood of slipping
  7. Here's a video of Brian Greene speaking about string theory:(it was recorded in 2005 so it may not be up-to-date on everything) https://www.ted.com/talks/brian_greene_on_string_theory?language=en String theory has become one of the newest possible theories that describe the universe. The theory says that there are more dimensions than just the three dimensions that we see. I was very curious to learn more about string theory because I wanted to learn more about modern theories in physics. String theory says that as we look at the makeups of quarks, we see that inside there are string-like balls of energy vibrating at a certain frequency. Each frequency creates different quarks and thus makeup different particles. Brian Greene however says that if one does the math, string theory doesn't work out with just the three dimensions. The math supports that there are ten dimensions and one time dimension. The other dimensions are so small that we do not see them. Greene also says that the CERN-the hadron collider- is what will give us the scientific evidence that there are other dimensions. This is because when two particles collide, if we record the energy before the collision and compare it to the energy after the collision, if the energy after is less than before than the the energy must have gone to another dimension, proving string theory is possible.
  8. I wish I could apply my physics knowledge in real life. Kind of like when I need to draw something, I have a picture in my mind that is so elaborate and perfect yet I can never place it on the paper. Like in basketball, if you were to give me the angle a ball is thrown, I can work out on paper at what speed to shoot the ball into the hoop like a projectile. I don’t have a good sense of force-probably because I am lacking the muscles. In gym class, when we had to throw the football, I thought I could throw it farther than I actually could. Or I would not throw it hard enough and it would fall short. I wish my brain acted like those in some fantasy movies where the person would look at a problem/situation and calculate everything instantly to figure out the problem. Even when I am driving a car, I might brake and slow down for a turn and take the turn too fast so all my books and bags in the backseat fly to the other side. I know that objects in motion stay in motion, I know how static friction could keep the bags in place..but somehow my results do not turn out perfectly. Like the lab we did in the beginning of the year, when we had to launch the ball and have it hit the book-we did it. But there is never enough time. I can’t be in a basketball game, press a “freeze” button, pull out a meter stick to measure the height, and distance from the hoop, the angle to the hoop and the force applied by me to launch it at a speed that will cause the ball to go in the hoop. It’s impractical. Life just doesn’t work the way to do everything perfectly.
  9. As if I wasn’t lucky enough to meet Brian Greene, (I have proof don’t worry everyone….*see image below*) I also bought one of his many famous books. The one I chose was The Hidden Reality. I was even luckier and also had him sign the book for me. I probably sound like I am “fan-girling” over this man but-let’s be honest I really am. I want to talk a little more about the book and Greene. He is a theoretical physicist who has done lots of work regarding the string theory. What is the string theory you might ask? I’ll give you a little history lesson. Firstly, when the electron was discovered, it unleashed the study of particle physics. Particle physics was developed using quantum mechanics. Einstein focused a great amount of time on the subatomic particles and created the Special Theory of Relativity. He then took Newton’s law of gravitation and created the General Theory of Relativity. Einstein’s findings led to a few predictions that are very intriguing: black holes and an expanding universe. The problem with particle theory is that it only works when we neglect gravity. The string theory was founded to determine the relationship between mass of a particle and the spin. Physicists discovered there to be a particle with no mass and two units of spin-also known as the graviton. If they implemented the quantum field theory to gravitons, the math did not work. Particle interactions occur at a single point of spacetime, at zero distance between the two particles. In string theory, the strings collide over a small but finite distance and the answers do make sense. So here’s a little example to make everything seem understandable: “Think of a guitar string that has been tuned by stretching the string under tension across the guitar. Depending on how the string is plucked and how much tension is in the string, different musical notes will be created by the string. These musical notes could be said to be excitation modes of that guitar string under tension. In a similar manner, in string theory, the elementary particles we observe in particle accelerators could be thought of as the "musical notes" or excitation modes of elementary strings. In string theory, as in guitar playing, the string must be stretched under tension in order to become excited. However, the strings in string theory are floating in spacetime, they aren't tied down to a guitar. Nonetheless, they have tension. The string tension in string theory is denoted by the quantity 1/(2 p a'), where a' is pronounced "alpha prime" and is equal to the square of the string length scale.” So with that, Greene has been studying the possibility of parallel universes. To quote Greene, “There are only so many ways matter can arrange itself within that infinite universe. Eventually, matter has to repeat itself and arrange itself in similar ways. So if the universe is infinitely large, it is also home to infinite parallel universes. Does that sound confusing? Try this: Think of the universe like a deck of cards. "Now, if you shuffle that deck, there's just so many orderings that can happen," Greene says. "If you shuffle that deck enough times, the orders will have to repeat. Similarly, with an infinite universe and only a finite number of complexions of matter, the way in which matter arranges itself has to repeat." I think studying more about this and having a deeper understanding is a goal I have. I am so excited to read this book and learn more about all the possibilities out there.

    pi

    I have successfully memorized 232 digits of pi. I don't know where I am headed-what goal i am trying to reach or whatnot. Telling this fact about myself to other people results in them giving me a very strange look followed by a blunt question such as: "Why?" Sometimes people have no real reason/motive. Well, I guess that's false because there always is but in many perspectives, people may think someone's motive to do something is pointless. As I think about this, I wonder what motivated those like Einstein. Someone who was constantly told that his quest for an answer was impossible-but he did it. What led him to choose that path? Galileo, Copernicus... why did they choose to go looking for their discoveries? I question their motives because in a way I envy them. How come I never think of looking at the stars or a rolling ball and answer the unknown. In physics, we answer the "how" questions. Maybe one day I will answer one that right now seems impossible, or even unthinkable. But for now, I will continue to climb the number of digits of Pi knowing there will never be an end; the universe is filled with so many infinities.

    geocaching

    I had an amazing experience geocaching with my friend the other day. For anyone who doesn't know, geocaching is basically the world’s largest scavenger hunt. All over the word, people hide caches. These can range in difficulty in finding it, the terrain of where it's located, or the size of the container. They contain a log book of all the people that have found the cache. The larger containers have a little treat inside-usually some little unique gadget-that are there for when the person(s) find the cache, they take something from the inside, write in the log book, & replace it with something else of their own. Now you may be wondering: how do you find the geocache? Simply download an app (not the $10 one, I have Cachebot) and it will navigate the cache by GPS. Thanks to our handy-dandy smart phones that have a built in compass, and GPS, this is possible. However, in some cases the GPS WAS TOTALLY OFF AND IT WAS SO FRUSTRATING SEARCHING ON THE GROUND IN A PILE OF LEAVES FOR A HALF HOUR WHEN IT WAS HANGING ON A TREE 20 YARDS AWAY. Anyways, I would like to thank all of those who made this experience possible. If one had not helped define Longitude and Latitude, create the first satellite, discover the poles, invent the smartphone technology, I would not have gone on this adventure. Science rules.
  12. Working a 15 hour shift with no break at all is not fun. That's how I spent my Halloween. I began my shift at 2pm and finally ended at 4(the clocks went backwards that's why it is 15). At some point between 1 and 3, I dropped my phone. Well, I actually tapped it & my phone had fallen from the counter to the floor smashing it a billion pieces. SO I want to invent something that will lessen the probability of me smashing another one of my phones. I know you probably are already thinking: "Duh Hannah.. that's what cases are for", Well okay maybe they stole my idea first (funny how that always happens?) but let's see how those work! The goal of the case is to lessen the effect of the force that the hit has on the phone. Thus, a cushion is put on the outside to increase the time of the force in contact with the phone which decreases the magnitude of the force. Or-we can create a screen/phone that is able to have padding or made out of a material that allows some give to when the phone drops to the floor. I would buy this phone in a heartbeat because I have shattered way too many phones already.
  13. One of the coolest experiences ever. I was able to meet Brian Greene personally prior to his keynote speech at the George Eastman House. NEXUS focuses on helping new entrepreneurs expand and grow to create efficient and modern businesses. Brian's speech focused on innovation. He talked about Einstein's Theory of Relativity-a concept I was semi-familiar with. He explained how one idea can be interpreted in so many different ways. Einstein's theory resulted in the theory of black holes, the Big Bang theory and others. He touched on the subject of parallel universes-a concept I found extremely intriguing. His speech really inspired me. He demonstrated how the physics community can truly create infinite possibilities. He branched out to everyone in the audience by explaining everything in a simple way. From his speech, he really concentrated on one big idea: we must look back at the past to make our future. All of the innovators he mentioned looked back at Einstein's work and questioned the components of the theory. He truly inspired me and so many others in the audience.
  14. real quick: watch this link because if you don't, you won't know what i'm talking about:) OKAY. So. A few days ago I came across this neat little video on Facebook. I guess I'll talk about each individual "trick": 1. They said this was a "ball in slow motion". Personally, I don't really think this one was as quite as successful/interesting. However, this trick does incorporate lots of physics!! Firstly, it's on a ramp. So if we were to calculate the acceleration, we'd have to know theta. Secondly, we can see that the honey does slow down the speed of the ball and there is a lot of friction inhibiting the ball to roll freely. All in all, did the ball really look like it was in slow motion? To me, not so much.. 2. Next we have the "Water Fire Starter". This one uses the curved bottle to focus light onto the paper and thus heating the paper up and bursting it into flames. I have some questions on this one and want to know how exactly it works. It seems to me that the idea is very similar to a magnifying glass but I wonder if the water inside the bottle helps this happen. Hmm... 3. The "No Leak Magic Bag"! Pretty cool from the looks of it, I must say and I am very curious to try this out myself. I looked up why it works for anyone who is curious, including myself. I found that "plastic bags are made out of polymers chains of molecules that are flexible and give the bag its stretchiness. When the sharp pencil pokes through the bag, the stretchy plastic hugs around the pencil, creating a watertight seal around the pencil…and the bag doesn’t leak." 4. "Liquid Stacking". The end result actually looked pretty cool but we all know it all works because of density differences. 5. "Invisible Bottle". I believe Mr. Powlin actually demonstrated this in our class last year. #indexofrefraction 6. "Dancing Liquid". This reminded me of my childhood when I used to play with cornstarch and water all the time. This trick uses the vibrations formed from the sound waves to create the "dancing liquid". 7. "Magic Water Barrier". Personally, I thought this one was actually wicked neat. Temperature of water effects the density, explaining why the two colors do not mix. 8. "Leidenfrost Effect". I was really interested in the physics behind this. For anyone who's interested, here's what and why it happens: "The Leidenfrost effect is a physical phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer keeping that liquid from boiling rapidly. At temperatures above the Leidenfrost point, the bottom part of the water droplet vaporizes immediately on contact with the hot surface. The resulting gas suspends the rest of the water droplet just above it." WHOLE BUNCH OF PHYSICS IN THIS PEOPLE!! Nothing brings me more joy than that. 9. "Reverse Allusion" Lots and lots of refraction, bending of light and optics :)))))))))))))))))))))) 10. "Reversing Liquid" Enough about me.. my question is for all of you physic nerds: why do you think this happens? (don't answer it Mr. Fullerton or Mr. Baker!!!!!)
  15. There's no equation that proves karma/jinxing is actually true (although if I were to create one specifically for karma, it would be extremely similar to Newton’s third law: for every action, there is an equal and opposite payback), but I am convinced Mr. Fullerton jinxed me. Maybe I fibbed a little about being an outstanding driver in my most recent post because it took me approximately 7 days, 18 hours and 26 minutes to get into my very first car accident!!!! The lady was wicked nice though so if there's something to be happy about, I was happy I hit her and not some mean old lady. Anyways, I'll tell you what happened in a nutshell: my neighbor and I just went to Dunkin Donuts and I was making my way back towards school. We reached just before the field house where we were stopped at a red light. Cars ahead of me, drivers were slowly inching forward and I took my foot off the brake to allow myself to inch forward as well. Just as we began moving, my neighbor hit my Hazlenut Coolatta (so sad :-() over and I spun my head to take a look at the mess that was made reassuring him that it was fine and it was just an accident. The moments my eyes were taken off the road, I hadn't noticed the car in front of me stop, so as I looked up to focus on driving again it was too late. My car rear-ended the car in front of me. Some paint was exchanged by both cars leaving my 2013 Black Dodge Avenger with a zebra-designed front bumper and hers, some gold-ish type of SUV looking thingy-ma-bobber (excuse my lack of knowledge of car models) with a touch of black on her rear bumper (it really enhanced the gold, I must say). This was an example of an inelastic collision. The mass of my car was lesser than that of the other car and she had a velocity of 0 m/s, therefore the equation would be =(+). However, momentum and energy was probably not conserved due to brakes, friction and a whole bunch of other factors. Key take-away: I need to invest in a car that cab detect a car/object ahead/behind me and will brake on its own so I won’t get into another accident :-) P.S Like I said in my last blog post, blame the blonde, nose-pierced driving instructor at East Rochester for all damages.
