  1. Particle Collider Reasearch funding should continue for multiple reasons. One reason because all of the medical success that has been achieved through this research; the use of protons and nuetron can help the treatment of cancer(www.fnal.gov). Another reason is the knowledge we can gain from it, for example understanding of outerspace. This technology can also measure cosmic rays. This is benefical to help us learn of how the surroundings around us are working. Lastly, the particle reasearch has been an active participant in industry. They use this research in power transmission cable by speeding up the protons sent. In all, this particle research funing should continue becuase of all of it beneficial atrributes it has brought to the society.
  2. That is a very long flight but I am sure it was more than worth it!
  3. I think it is so cool how something that seems so common on Earth is not available everywhere!
  4. Thats a lot of great information that is interesting and knowledgeable
  5. This post is hilarious and great example of physics in the world of lacrosse!
  6. That so cool! I have always wanted to be able to play the guitar.
  7. A tool that provides direction by the use of magnetism is based on the basis of physics. This tool, the compass, has been used for many centuries and helped guide history through various explorations. Today, this tool is not used as much as it had been in the past but if you are ever lost it is a great instrument to help you find your way. Magnetism is one of the first bits of science students learn about in school and just about the first thing we discover is that like poles repel opposite poles attract. If you hold two bar magnets so their north poles are almost touching, they will push away from one another; if you turn one of the magnets around so one magnet's north pole is near the other magnet's south pole, the magnets will pull toward one another. That's all there is to a compass: the red pointer in a compass - the magnetized needle - is a magnet and it's being attracted by Earth's own magnetism called the geomagnetic field. Earth behaves like a giant bar magnet with one pole up in the Arctic and another pole down in Antarctica. Now if the needle in your compass is pointing north, that means it is being attracted to the Earth's north pole. Since unlike poles attract, the compass is being attracted to must be a magnetic south pole. Furthermore, the thing we call Earth's magnetic north pole is actually the south pole of the magnet inside Earth. Originally this concept was a little challenging to grasp but then I realized all I need to remember is that opposites attract. Earth's magnetic field is actually quite weak compared to forces like gravity and friction. For a compass to be able to show up the relatively small effects of Earth's magnetism, the effects of these other forces must be minimized. That is why compass needles are lightweight and mounted on frictionless bearings. Compasses provide direction to our destination which in the end can be more useful than most other instruments we use in our daily lives.
  8. As the end of the school year comes to an end I am becoming ecstatic just thinking about camping. Every year, my family goes to the Thousand Islands and camps out. During that week we spend our time swimming, jet skiing and hanging around the campfire. That is a week I look forward to every year. A very useful tool that needs to be brought every year is a flashlight. We need this instrument because walking around at night can become directionless without know in which way your destination is. Through this blog I hope to inform and remind others of how the physics of a light flash works. Everyone knows know flashlights has batteries in them; what a battery does is it uses a chemical reaction to put all the (+) charges on one side of the battery and all the (-) charges on the opposite side of the battery. Because like charges repel each other the (-) charges do not like being all together at one end of the battery. When a wire is connected from one end of the battery to the other end the (-) charges, electrons, are able to flow through to get away from each other and get to the (+) charges on the other side. This idea is an example of a circuit. A flashlight is a kind of circuit with a light bulb on the wire. A light bulb is just a device that changes the energy of the moving (-) charges into light. Pushing down on the switch of the flashlight connects the wire with the light bulb to the battery and forms the circuit. In the setting of camping, I am very grateful that circuits are dependable and safe because camping could be much more difficult with out them: thank you physics!
  9. Even though the month of March had gone by fast , it is a month of television watching and switching through various channels. This phenomenon is all because of one event: March Madness. Overall, those two weeks I had spent a good portion of my time at home in front of a screen. So when it was time to write a blog post electricity became an easy topic to write about. Especially because during class we had recently finished a unit on electricity. From what I have learned in class as well as doing some research I had found that the logistics of a television remote are actual quite simplistic. So simple that by pushing a button on a remote control sets in motion a series of events that causes the controlled device to carry out a command. The process can be summed up within three steps. On, You push the volume up button on your remote control, causing it to touch the contact beneath it and complete the volume up circuit on the circuit board. The integrated circuit detects this. From there, the integrated circuit sends the binary volume up command to the LED at the front of the remote. Finally, the LED sends out a series of light pulses that corresponds to the binary volume up command. Though the basics of this seems to be simple, interference within the connection of the circuit can be complicated at times. It is crazy to see how something we enjoy and unit with is full of physics!
  10. Spring is one of my favorite seasons because for me that means it is lacrosse season! During practice one day when I was trying to think of a topic for a blog post it became obvious to me that lacrosse is a perfect example of physics in action in my life. Newton's Three Laws really became the primacies at which I was able to figure out the physics within this sport. Newton's First Law: An object at rest will remain at rest until acted up by an external force. In the case of lacrosse, the net cradles the ball, which connects to the stick before a player finally acts upon it. A centripetal force exists on the ball as the player throws it; the ball's friction against the net keeps the ball in the pocket while the stick accelerates around. Once the ball gets released, it will continue in a straight line until acted upon by an outside force such as another player's stick, or simply the force of gravity as the ball falls to the ground. Also by using Newton's Second Law you may calculate the force of a player's throw using Newton's second law: Force equals mass times acceleration. The acceleration applied to the ball during the throw directly determines the force of the pass, because the mass remains constant. And lastly, Newton's Third Law points out that for every action there exists an equal and opposite reaction. When throwing a lacrosse ball, the stretch in the netted pocket and the motion of the ball counteracts the force put into swinging the stick. The ball gets forced forward as a reaction to the work applied to the stick.
  11. This weekend I was involved on the Dodge for Josh Dodgeball Tournament. This tournament raised money for the Josh Rojas Foundation. This event proved how physics can not only be fun but at times can also be painful. In the game of dodgeball the entire objective is to create and form collisions. In this sport there are two typees of collisions, inealastic and elastic. One can witness the collisions by watching a player get hit by a ball or when two balls collide into one another. IN an elastic collision, the total momentum and kinetic energy are both conserved. In an inelastic collision, the two objects move as one object and one mass. In this collision the momentum is conserved meanwhile to kenetic energy is being converted into internal elastic potential energy. The remainder of the kenetic energy is then converted into heat and sound energy. This tournament went by too fast but I guess that time truely does fly by when your having fun!
  12. Since the price of salt has increased and as a result the streets will be more dangerous to drive and walk on a question came to mind: Why do people slip? After beginning to fully understand the logic behind friction I figured out a basic understanding of why it happens. When we walk, we need friction between our shoes and the ground to give us the ability to move forwards. Without friction we would not be able to remain standing for very long, let alone walking. If at some stage the amount of friction that the ground to the shoe contact provides less than we need, then it will result in slipping. Furthermore it is important to know the friction a particular surface when walking on it.
  13. Since it is winter I cannot wait to sled. This year since I am in physics I want to understand sledding better by using Newton’s laws of motion. Newton's First Law of Motion, the Law of Inertia, states that an object's velocity will not change unless it is acted on by an outside force. The greater mass or velocity an object has, the greater its inertia. For example, it takes a pretty strong push to get you and a friend on the same sled moving, but once you gather speed you'll keep going even at the bottom of the hill where the run flattens out. It takes much more force to stop you and your friend on the sled than to stop an empty sled. Newton’s First Law is in so many simple activities in our lives, sledding just so happens to be a fun way to express the solution of how it is possible.
  14. Frequency: At any point in the air near the source of sound, the molecules are moving backwards and forwards, and the air pressure varies up and down by very small amounts. The number of vibrations per second is called the frequency (f). It is measured in cycles per second or Hertz (Hz). The pitch of a note is almost entirely determined by the frequency: high frequency for high pitch and low for low. Human ears are most sensitive to sounds between 1 and 4 kHz - about two to four octaves above middle C. That is why piccolo players do not have to work as hard as tuba players in order to be heard. The lips control the air flow: Brass players can make musical sounds with just their lips. This is one of the first things a brass player learns: you close your mouth, pull your lips back in a strange smile, and blow. The result may be anywhere between a low pitched or a high pitched musical note, depending on the tension in your lips and other parameters. Since I am a current trumpet player in the Symphonic Band for our High School this part of Physics truly relates to my everyday life.
  15. When skating, the skates of a hockey player do two things: They glide over the ice and they push off the ice with the edge, in order to gain speed. The physical properties of ice is what allows hockey players to maneuver the way they do. For instance, the low friction of the skate blade with the ice and the physical properties of the ice is what allows a player to speed up, or stop. A hockey player propels himself forward by pushing off the ice with a force perpendicular to the skate blade. Since the friction of the blade with the ice is almost zero, this is the only way he can propel himself forward. The figure below illustrates the physics behind this principle. Though I do not play hockey I love to watch it my favorite NHL team is the Bruins. Also I love to go and support our High School Hockey Team.
