How physics has changed my life

From a very young age, my dream was to become a scientist. I didn't know that I wanted to discover the god particle or find a cure for cancer or synthesize a new element. I had no idea how broad the term "scientist" was and how many denominations it had, either. The only thing I knew is that it would be pretty awesome to be the guy who mixed two chemicals in a beaker and watch it explode, just like in the cartoons. As soon as school became more serious than learning how to write, I already p

Theoretical Physics VS Experimental Physics!!!!

Theoretical physicists develop "mathematical models that both agree with existing experiments and successfully predict future results", while experimentalists devise and perform experiments to test theoretical predictions and explore new phenomena. Although theory and experiment are developed separately, they are strongly dependent upon each other. Progress in physics frequently comes about when experimentalists make a discovery that existing theories cannot explain, or when new theories genera

Why don't jet packs exist?

With all of the renowned technological advances made within the last few decades, many people have sought to create a jet pack for commercialized use. However, although prototypes have been seen, it has been met with relative failure. This is due to the materials required to reduce the weight. Gravity creates an acceleration downward, while the thrust of the jet pack would attempt to create a net force upwards large enough to counteract this force. Unfortunatley, the heavy mass of the person pre

Physics jokes to ease the pain of this upcoming midterm!

In the early 1900's, name foreigners came to america, and they had bad english skills, espeicaly with tense and past tense. So, one day, a german who just entered the country lost track of the time, as he needed to catch a train , so he asked a physicists "What is time". The physics replied "You will have to ask a philosopher that question, I'm only a scientist". Your mother is so fat, men are actually attrracted to her, according to General Relativity Many people espouse the works of Rene

A Really Great Study Tool!

I know all of us have a habit of just getting by in physics, especially on Wednesdays I mean, I'm not going to lie and say I dedicate the full time during these independent units, and sometimes it is honestly difficult to grasp the concept using strictly the materials given. One website that Mr. Fullerton gave us towards the beginning of the year that really helps me get quick and concise information. HyperPhysics allows you to search for specific topic and gives you the facts and diagrams you

Standard Deviation

While we use percent error to dictate how far we off in class, there are far more efficient ways of defining the error of the set. Standard deviation, for example, given a value, will give rise to numbers that fall within one S.D., two S.D. and so on. "One can find the standard deviation of an entire population in cases (such as standardized testing) where every member of a population is sampled. In cases where that cannot be done, the standard deviation σ is estimated by examining a random s

Equation Dump Cheat Sheet

It has come to my memory that equation dumps are a staple to our physics careers. So, as taken from an old sheet from last year, I figured I might as well start memorizing early! The better recall now the better recall later!

The Perfect Fifth

For those of you who don't have any musical knowledge, the perfect fifth is the best sounding sound interval to the common ear. It is the key ingredient in structuring chords based around the root. With a 3:2 ratio, it creates a nice and pleasing sound to the ear. The most common example of a perfect fifth is a C to a G. Kepler himself, founder of the planetary laws, researched the beat frequencies of the error bound for an imperfect fifth tuning. Just a slight slip-up in tuning can create an un

RIT Physics Program

I am excited to start my college physics programs next year. Since I have collected so many credits (Thank you Mr. Fullerton and Mr. Powlin!), I will not need to take the first two courses of Physics at RIT. Therefore, I will be taking a physics exploration class the first year. This will allow me to look at all different kinds of physics, even units we never covered in high school. I am very enthusiastic about the quantum level of physics, and I enjoyed the modern unit in B, so I think i will b

Mario, the Physics Teacher?!

Super Mario Bros defies many different forms of physics. Assuming his round belly carries some weight, I would be nice to give him a weight around 200 pounds. Since he can jump over 5 times his body weight, his legs would need to lift at least a tonne to come close to the approximate strength to perform such a feat. In addition, kicking the koopa shells would create an equal and opposite force back onto his feet. He would not be that agile if he were wearing steel-toed boots, so it should hurt a

The AP Exams

As late as it might be, I'd just like to take a bit to reflect on the ap exams. We worked our butts off to try and achieve the highest possible. I bough review books, took old practice exams, and worked out all part 2 problems from recent years. Needless to say, i was completely prepared by may to take that test. And yet, I still walked into that exam and came out a little uneasy. The mechanics exam was relatively straightfo​rward, with just one part two that gave me grief. However, mr. Fullerto

Quarter 4 and The End of Senior Year

Guys, we have just finished the hardest classes in the school. I think I speak for all of us that senior year was quite stressful, but a great relief as well. We gained knowledge that far surpassed any other year. With Physics and Calculus placed 2nd and 3rd period conveniently, I think we all became morning people! To be honest, I never expected leaving to really effect me the way that it is currently. I am truly going to miss all of my high school friends. We have all toughed out our years, pu

Top Three Things you want to memorize for a phyiscs test!

3)MOMENTS OF INERTIA. These simple equations are a pain in the butt and stop you short of a point or two on a question if you don't know them. [ATTACH=CONFIG]584[/ATTACH] 2)DERIVATIVE RELATIONSHIPS. Enough said. These relationships come in handy on all graphing questions and can pick up points on the questions that are specific to derivatives. a = dv/dt v=dx/dt I = integra(mr^2) and so on... 1)KINEMATICS EQUATIONS. They are everywhere. EVERYWHERE. Those who know when to appropriately

Bring us the Integrals!

I remember the first time we saw the integral was in physics C. It was extremely intimidating because we struggled to make sense of the differential equations, let alone evaluating the integral itself. The very first problem we got, we were spoon-fed the fact that the integral of (du/u) was equal to ln(u)+C, and that made absolutely no sense to me. Now, into the third quarter and after attending the calculus school of hard knocks both 2nd and 3rd period every day, i think its is safe to say that

The Laser Lab: What I did this Summer

This summer, I worked under the tutelage of Wade Bittle and Dr Steven Craxton at the university of Rochester. I worked on a project called Dewpoint calculation using flow transducers. The preliminary time at the internship was spent gaining a basic knowledge of integration, and learning about the omega lasers functions and work schedule. Although we never got to see a shot (a single blast would vaporize our corneas) we had a good understanding of the process going on. When fusion occurs, there i

net F = MA

As simple as this equation seems, it is a staple in mechanics. It has many different applications. These uses vary from setting up equations to find tensions to simply finding the net force of an object in motion. It is 0 when an object is in constant velocity or when the system is in static equilibrium. Then, when we convert the quantities into rotational motion, and we get net Torque = I(alpha). For an equation that seems very simple and easy to apply, there exist tricky problems that require

My First Blog

Hello world! It is a pleasure to make your aquaintence. I have taken a liking to physics since I took AP physics B. Assuming that we are all nerds, I would guess that this statement would be common (we're all making a blog post on a physics site, arent we?) I am strong in logical reasoning and arithmetic, and would like to improve my test-taking skills throughout the course. I am taking AP-C to further my experience in the field to prepare for college and future work. I can't wait to use calc

Tips for Students Entering Next Year

1. Keep up with the blog posts!!! DO NOT PROCRASTINATE LIKE I DID, IT IS NOT VERY FUN TO DO. The blog posts are not a large amount of work, and they are a massive grade booster for the class. 2. Read the Textbook!!! The few times I took a look at Tipler, I gained valuable, relevant information on the current topic in class. It is by far the most useful tool Mr. Fullerton will give you when you miss a day. When I was out sick for 3 days, the textbook taught me the entirety of Gauss's law, whic

Furniture Moving

The other day, my dad and I were moving a couch for my uncle. For arbitration, let's say the couch weighs 100 N. Because my dad stands 6 cm (.06 m) inches taller than me, it can be assumed that the couch will be offset as well. If the couch is about 4 meters, the angle is about arcsin(.06/4) = .015 degrees from the normal or 89.985 degrees from the x axis. Therefore, if each us lifted an equal amount, we would lift the couch with 50 N each. However, we would be generating a torque equal to the F

Quarter 3

This quarter was a roller coaster. With my grade in the tank at the beginning after one bad test, I have been climbing very slowly ever since. I enjoy the fact that we are actually having more independent units this quarter. The very first one was very effective, and although we took for granted the class time in these units, our grades showed significant prowess from these tests. I am both excited to buckle down and commence prep for the exams soon, but I am afraid of this new induction unit! I

Luke's Patented 5 Steps to a 5 (TM)

Here are my top 5 tips to performing the best possible: 5) TARGET THE UNITS IN WHICH YOU PERFORMED POORLY ON TESTS. If you aced that rotational motion test or blew through the early dynamics tests, odds are you don't need to prioritize your study sessions around them. Focus on the tough stuff that you know you could use the extra points for. Getting those extra points that few students usually get will boost a 3 to a 4 and a 4 to a 5 4) DO EVERY PRACTICE QUESTION POSSIBLE. Each released AP

More Physics, More Baseball

When I was in the 8th grade, I always dreamt of taking physics in high school. Unfortunately, my motives at the time were somewhat naive; I used to think that a physics background would allow me to never miss-throw a baseball again. With a handy protractor, I believed that I could throw a baseball any distance I desired with little effort as long as I threw it at the perfect angle. Physics has since crushed this dream: the ball will only have a finite amount of time in the air, based on the comp

Physics of Volleyball

Volleyball is an interesting sport. It's very fun to play with friends with no serious competition, but once it's played for real, it is a difficult sport to master. You'd think it would be physically impossible to hit a sphere with two cylinders. Our studies of momentum have indicated that the collision would bounce off at irregular angles. Since it is easy to make passing unpredictable, I do my best to flatten my wrists by rotating them. Creating a flat platform, I am able to successfully pass
