The Mag lab near Tallahassee has created a 45 Tesla Magnet. This Magnet is 800,000 more powerful than the earth magnetic field. The Magnet was build by placing a coil of wire inside a coil of wire inside a coil of wire ... creating a massive magnetic field. The Magnet proved so strong that a camera crew lost half its recordings just by being in the same building as the magnet.
Let’s say we have a person with a mass of 100 kg who can run at 5 m/s.
Now we can make use of Einstein famous equation of E = MC2 :einstein)
When the person is at rest, the total energy of the person is 100 * (3x108)2 or 9x1018 J
When the person is running, their Kinetic energy can be defined as ½mv2
Ke = (½)*(100)* 52
Ke = 1250 J
Therefore the person total energy is (9x1018 + 1250)J
With a little reworking of the equation, we can get Δ m = (Ef – Eo) / (C2)
Δ m = (1250 J / 9x1018 m2/s2)
So I figured I’d, write about why our water bottle rocket failed so miserably on arts fest. Our goal was to use parachutes that would cause our rocket to slowly descend to the ground. Instead of using just one, we figured using two would slow our rockets fall even more. In theory this would have worked fine, however when our rocket reached its maximum height and the nose cone fell off exposing the parachutes, instead of fully opening, the two chutes tangled together and didn’t fully open. The un
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
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
Has your hand ever been so cold that it went numb? Well how about when it was 90o and you were outside in the sun, no, well this has happened to me before. Over the summer I worked part time at clover home leisure. Part of my job was to fill up propane tanks. Normally not a big deal, but sometimes we get massive propane tanks with purge valves. While filling, the purge valve forces the air out. When tank is done filling, the purge value starts spitting out massive amounts of propane. Propane sto
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
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.

Anyways we fill the buckets with water and a b
The physics of Swim Paddles. Some times at swim practice our coach makes us use these paddles.
These paddles typicality increase how far we go with each stroke while slowing down our stroke as it takes more force to pull. This because with the paddles, our hands have a greater surface area. When we pull our arms through the water, we pull more water behind us. Based on the law of conservation of momentum, if I catch and push more water at the same velocity backwards I will have a greater veloc
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 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
The Physics of how i time traveled into the Future and therefore these blogs posts aren't really late technically kinda probably.
Well um these blogs posts were due last night, which I didn't realize, also i thought they were just extra credit. So Ill discuss how I could have potentially traveled into the future which caused me to submit these late.
As we learned last year E = mC^2. As the speed of a particle increases in speed, the mass increases. But while the mass increases, time will a
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
Ever heard of the Superconducting Super Collider before? I certainly hadn't.
In 1983, plans for the Superconducting Super Collider were being developed by the U.S. Department of Energy. Its planned ring circumference was 87.1 kilometers with an energy of 20 TeV per beam of protons – numbers that surpasses those of the now operational Large Hadron Collider by a factor of three (27 kilometer with an energy of 7TeV per beam). The project initial goal was to detect the Higgs Boson. The project be
I found the most amazing video of superconductor levitating from a magnetic field. You absolutely have to watch this video!!! So basically a sapphire is coated with yttrium barium copper oxide. When cooled to -301oF, the saphire becomes a superconductor. The superconductor experiences no electrical resistance. For some reason the magnetic fields aren't able to penetrate because the superconductor expels fields from the inside. This leads to something called quantum locking which holds the superc
As I talked about in my last post, drag force is a huge factor in limiting performace in the pool. So how can we combat this problem?
Well for dedicated swimmers, shaving can make the difference. Since many races come down to fractions of seconds, any hair you can cut off can mean the difference bewteen first and second! Optimizing the distance you travel in the air when you dive of the block can make or break a race. As stated in my blog post, water is over 700 times denser and will offer far
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.
In Swimming, reducing drag is a huge factor in decreasing your time and increasing performace.
Water is more than 700 times denser and 55 times more viscous than air. There
are three main types of drag that act on a swimmer: friction, wave, and pressure
drag. Frictional drag is the result of the interaction between the swimmer’s
body and the water molecules and serves to slow down the swimmer. However, this
drag also propels the swimmer through the water (Newton’s 3rd law).
As the s
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
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!!!
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!

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
Well I am sure that you are all familiar with the LHC (Large Hadron Collider) discovery of the Higgs boson, but it looks as if the LHC as made another discovery, this one accidental!!!
After 2 million lead-proton collisions, the CMS team at the LHC discovered that several pairs of particles - that were created from the collision- flew away from each other with their respective directions being correlated. I am not a particles physicist so I have really no idea what this means or the significa
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.
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
