bungee cord physics

Well, I thought of yet another aspect of swimming to analyze for my blogs posts!!! Sometimes at practice we use these bungee or stretch cords to work on resistance training. The premise is simple, strap one end around your self, and the around the block at the end of the lanes. The bungee cords act just like a spring in that F = -Kx, the further the displacement the larger the force. As you get closer and closer to the other end of the pool, the force pulling you back becomes larger and larger.

Jason Padgett sees the world in Math equations!

Jason Padgett has Acquired Savant Syndrome. 10 years ago he was beaten and kicked in the head by some muggers after his jacket. While recovering in the hospital he became obsessed with mathematical equations. Apparently the damage to his head allows him to view everything he sees as a Math equation! Padgett turns these formulas into intricate diagrams called fractals. Prior to his accident Padgett was a college drop out and had never taken a college level math class before. An example of his wo

Below Absolute Zero?

Recently physicists at the Ludwig-Maximilians University Munich and the Max Planck Institute of Quantum Optics in Germany have registered a temperature a “few billionths of a Kelvin” below absolute-zero. Now you’re probably thinking what??? If the Kelvin measurement of temperature is a measure of the energy of particles then how can we achieve a negative temperature and thus a negative energy? Furthermore if at Zero Kelvin particles stop moving how can you take energy from them? Well some sci

Electromagnetic Rail Gun

The navy is developing a prototype for an Electromagnetic Rail Gun. The Rail Gun would be use massive magnetic fields to accelerate a projectile at over 5000 miles per hour. The projectiles would have so much kinetic energy that warheads would become unnecessary components to the projectile. The projectile would be able to devastate a bunker just by making impact with it, making explosives unnecessary. Clearly such a weapon would be extremely useful in a wartime situation.

Benefits of Nuclear Fallout

I found an interesting article about how nuclear fallout has aided in studies on brain development. Nuclear fallout introduced small amounts of carbon 14 into our atmosphere. When our cells divide, they incorporate carbon from the environment. So the carbon 14 released from nuclear bombs eventually makes it way into the human body. This means that carbon 14 can be used to measure the age of cells. A team at the Karolinska Institute used this to show that new neurons were produced in a small part

The physics of hypothetically cheating at swim practice

The physics of hypothetically cheating at swim practice. During Saturday practices, our coach has us do stations. One of these stations involves sprinting with a parachute. As you can see the parachute is quite small but despite this, it still creates a whole lot of drag. The parachute is very thin and creates a large pocket that water gets trapped into. As the parachute is pulled through the water, the water getting caught in the pocket creates drag. Now 100% hypothetically speaking if anyone

Pain Pong

So last night the swim team got together for some pizza and to hang out. Being highly intelligent teenagers, we decided to play some pain pong. For those of you who aren't familiar with pain pong, it is a variant of ping pong where everything you loose the point you turn around and your opponent smashes the ball with the paddle at your bare back. Naturally if your quite bad at ping pong(like me) the game can get very painful, but why? Well its because of physics, more specifically impulse! Δp=

Last blog post

So I was reserving my last blog post for my momentum video I made last year. Unfortunately I couldn't find it last night. I went to Mr. Powlin today to get the video but it wouldn’t upload to the site, or to my email or Google drive for some reason. I’ll try to find the video again tonight, but if I can’t just picture me getting shot bare skin with an airsoft gun.

Rap about the large Hadron Collider

I find an amazingly informative video on the Cern's LHC. It covers basics particles physics with some other things. The best part, Its a rap!!! It was interesting to see the video theorizing the discovery of the Boson Higgs particle. The video - being made in 2008 - is abit behind with the times as the Higgs particle has recently been detected by experiments done with the LHC.

The Physics of the PowerTower

The physics of the Powertower. So as previously mentioned in another blog, on the Saturday practices we do stations. One of the stations is doing sprints with THE POWERTOWER. What’s a Powertower you ask? Well if you have ever been to the pool and seen those giant red buckets attached to the metal frame thingy, that’s the Powertower. I’ve included a picture because I’m guessing none of you know what I’m talking about. [ATTACH=CONFIG]583[/ATTACH] Anyways we fill the buckets with water and a b

International Workshop on Future Linear Colliders

Two weeks ago on October 22, University of Texas at Arlington hosted a five day workshop devoted to the future of high energy linear electron-positron collider. At this workshop the future of two projects were discussed,the International Linear Collider(ILC) and the Compact Linear Collider(CLIC). The ILC is planned to have a collision energy of 500 GeV. The host country of the ILC has not yet been selected. The CLC is projected to have collision energy of 3TeV. The CLC (if built) will be located

University of Michigan has developed a coating that repeals virtually any liquid

Engineering researchers at the University of Michigan have crated a nanoscale coating that is super effective at repelling liquids. The major difference between this coating and other coating is that with other coatings, liquids with very low surface tensions such as oils, alcohols, and organic acids stick to the coating and eventually diffuse through the coating; however with this coating, even liquids with low surface tensions are repelled. After testing well over a 100 liquids, the team at Mi

Dark Matter

It seems the search to prove the existence of the elusive Dark Matter might soon come to a close. A Minnesota mine, half a mile under ground, seems to have detected the existence of Dark Matter. For those of you who don't what Dark Matter is, I'll give a brief explanation. The ordinary matter that we can visibly see makes up an estimated 15.5% of the universe. Planets, Stars and pretty much everything else in space is made up of ordinary matter. However 84.5% of the universe's matter is estimate

Antimatter

Antimatter is a very strange concept in physics. Antimatter consists of anti particles that have the same size and mass as their corresponding ‘regular matter’ but opposite charge. For instance a positron is the size of an electron but contains a positive charge. The current theory for the universe, the Big Bang Theory, predicts that an equal amount of matter and anti matter were present at the beginning of the universe. But today, anti matter occupies a negligible amount of the universe’s compo

This quater

Reiterating Dave's recent blog post, I thought I would review what this last quarter has been like. So this quarter covered the E&M portion of the Physics C course. My general opinion is that the jump from Physics B to Physics C was far easier for mechanics than the jump for E&M. From the first two exams I learned that I was horrendously bad at the E&M free responses. I also found while taking the test, I would realize that I didn't really understand the material as well as I though

My take on our independent unit

This is our second independent unit in a row, meaning we haven't had traditional class in a very long time. This one seems a bit more difficult then previous ones though. Unlike previous independent units, I don't remember much about magnetism from last year making it more difficult. Magnetism also employs more complicated math like cross products and calculus based equations then the other independent units. I found it hard to understand the textbook and the only thing that stands out from the

The physics of lane line reels

So at yesterdays practice my coach made us take out the lane lines and put them on the reel after practice. As we spin the reel, the reel becomes increasing difficult to spin because the additional mass of the lane lines. I decided it would be a great blog post to find out how much the moment of inertia changes for the reel once all of the lane lines are put on. I’m going to make some rough estimates on the dimensions of the reel since I couldn’t find them online and I can’t go in and measure

The usefulness of physics

Have you ever wondered if physics would be applicable to your life? How can you make what you learned in physics useful? Well Physicist Dmitri Krioukov used physics to get out of paying a $400 traffic ticket. Dmitri Krioukov wrote a paper titled "The Proof of Innocence" to explain to the judge that his traffic violation for running a stop sign was the result of the officer suffering from an optical illusion. The end result, Mr Krioukov no longer has to pay the ticket!! This proves one of two th

Frozen Door

So this morning I went out to warm up my car for practice, only to discover that my car door was frozen shut. Now I know what your thinking, why don’t you just pull harder, well I did but unfortunately the door handle was poorly designed. As shown in the picture below, one corner of the metal holding the handle on is detached. [ATTACH=CONFIG]568[/ATTACH] In order to open the door, the handle is pulled up and out at an angle. Under normal conditions, i.e., the door not being frozen shut

Course Reflection

I figured I would finish my blog posts with a reflection of how physics went this year. At the beginning of the year, Mr. Fullerton introduced us to integrals. I had absolutely no idea what how to do them since we hadn’t covered it in math yet. Fortunately by the time they finally came up on a test, we had gotten to them and calc and I finally understood them. Overall the calculus included in the course was fairly basic and wasn’t very hard. The independent units were definitely something new

The Oh-My-God Particle

So I read something really interesting about a particle called the “Oh-My-God particle”. Detected on October 15th, 1991 the particle was a proton that was traveling at nearly the speed of light. In fact it was traveling at 99.99999999999999999999951% of the speed of light. The proton had the energy equivalent of a baseball traveling about 100 kilometers per hour (imagine getting hit in the head and knocked out by a particle too small to see). Even the particles produced in our particles accelera

Dark Energy

Since I’ve already done a blog on dark matter I thought why not do one on dark energy as well! Like dark matter, the existence of dark matter has yet to be proven. Despite this, dark energy is theorized to ‘exist’ in very large quantities. Current models have dark energy occupying 68.3% of the universe. So if we can’t prove dark energy exists why do physicists believe it exists? Well because it’s the only thing that would explain why the universe is accelerating. We know from red shift that the

Pain Pong to the extreme

Well i thought my last post was about the physics of pain pong(a painful variant of ping pong) was pretty crazy. Well a professor from Brigham Young University took it to a whole new extreme. Professor Harold Stokes used a cannon to launch a ping pong ball at himself at over 500 mile per hour. Now that's dedication to teaching!!!

Physics of Ironclad

So I was watching Ironclad and decided that I could use the movie to blog about physics stuff. The main character, Templar Knight Thomas Marshal was ridding around on his horse at Rochester castle, wailing his flair around, total bossing up those bad guys, when suddenly he is pulled off his horse. A huge crowd of bad guys form around him beating him with axes and hammers and stuff. Luckily our Templar Knight is tied to his stead who eventually/after an eternity, the horse decides it would be a
