  1. Hey y'all, Chris, a student at Cornell, wakes up at 8:59am for his 9:05 class. If the class is 1.5 km away, at what constant velocity does he need to travel in order to make it to class at 9:05? Neglect air resistance.

  5. This launch was nearly identical to our third launch, except we remembered to take screenshots. Pre-Launch Design Release Team Name: StackBNimble Corp.

  6. This past Friday at Arts Fest, we brought Kerbal Space Program into the real world. Every year at Arts Fest, the Physics 1 students are given a project in which they need to construct a rocket out of a 2 Liter bottle, which is then launched on the track. If the rocket is in the air for at least 7 seconds, full points are awarded. This year, Mr. Fullerton gave all of his Physics C students the same project. If our rocket remained in the air for at least 7 seconds, then our reward would be 100,000 kerbency for our team in Kerbal Space Program. Our team, Stack B Nimble Corp., received the full re

  8. I've never heard of Cherenkov Radiation before. Very cool!
  9. A couple days ago, a Swiss skier named Andri Ragettli landed the first ever 'Quad Cork 1800', in which he flew 38 yards off of a jump in Italy, making five full rotations and four head-under-body spins. The video of the jump is attached below. The true difficulty of landing such a trick is very clear when considering the physics behind it. First, in order to be in the air long enough to perform such a trick, a skier needs to gain a great amount of kinetic energy as he descends from the top of the hill. In order to do this, the height of the top of the hill should be maximized so as to maximize
  10. I have played the saxophone for a very long time and really enjoy it. Although I have played it for so long, I have never learned the physics behind how blowing on a little piece of wood generates sound. In making a sound on the saxophone, one blows air at a high pressure through the mouthpiece. The reed controls the air flow through the instrument and acts like an oscillating valve. The reed, in cooperation with the resonances in the air in the instrument, produces an oscillating component of both flow and pressure. Once the air vibrates, some of the energy is radiated as sound out of the bel
  11. Recently in my BC Calc class, we've been talking about series and in some cases the application of them. The harmonic series is especially applicable to music: in music, strings of the same material, diameter, and tension whose lengths form a harmonic series produce harmonic tones. Another application of the harmonic series is the Leaning Tire of Lire, a theoretical structure. Suppose that an unlimited identical books are stacked on the edge of a table in such a way that the maximize the overhang. In order to maximize overhang but prevent the structure from collapsing, we can apply the formula
  12. Mr. Fullerton recently gave us a hand out explaining electromagnetism and how it directly relates to Einstein's Theory of Special Relativity. According to the theory, length and time are not absolute measures, but can be perceived differently based on the motion of the observer. This can be applied to current in a wire. Take a wire with no current flowing in it. As a whole, the wire is neutral as there are equal numbers of protons and electrons. When current flows through the wire, the electrons flow in a specific direction. The density of positive and negative charges in any section of the w

    Silver Egg Illusion

    I've never heard of the silver egg illusion before. Very cool!
  14. I never knew that turbo systems pump more air into the cylinders of the car.
  15. I will definitely beat you in Jenga.
  16. That is so cool. I can't begin to imagine all of the complex computer science involved in creating something like that.
  17. I never knew that cruise ships have thrusters. I can how important they are considering how of an impulse they need to deliver in order to keep the boat going in the right direction!
  18. Recently, astronomers discovered a solar system much like ours that could potentially support life. Seven earth-sized planets orbiting nearby star Trappist-1 were found this past week. The solar system is 40 light years away from the Earth. At least three of the seven planets are the right temperature to sustain life. They're rocky and could have oceans. Their orbital periods range from 1 to nearly 13 Earth days. All of the planets are located within a distance from Trappist-1 that is 1/5 the distance from Mercury to our sun. However, Trappist-1 is a relatively cool star, making the temperatur
  19. Last week, I went bowling for the first time in a long time. I noticed that there is a lot of physics in the sport. When rolling the ball, the bowler applies a force to the ball causing it to accelerate and travel with a relatively constant velocity down the lane. The reason that the ball does not decelerate very much at all is because a substance with a very very low coefficient of friction is applied to the surface of the lane, making the force of friction on the ball small, but nonzero. If the force of friction were zero, the ball would not rotate at all. Bowlers also commonly apply a torqu
  20. Last week, we began the archery unit in gym class. One thing that was especially interesting was when Mr Carrick brought in his compound bow. The compound bow, unlike the longbow and recurve bows, utilizes a system of cams and cables, which is a basically a Pully system, redistributing the tension in the string of the bow. This allows the archer to hold the bow at full drawn length with less force than the maximum draw force. This is especially useful for hunters, where bows may need to be held at full draw length for long periods of time. Mr Carrick would shoot alongside us, where most of us
  21. This past week, a group called the Saakumu dance troop featuring Bernard Woma came to IHS. Their performance featured multiple instruments that are atypical in the United States. For example, they brought with them an African gourd drum, which looked a lot like a curved marimba. However, a marimba's resonators are hollow pipes, whereas this gourd drum's resonators were gourds, the vegetable. This instrument is played by striking wooden bars with mallets. The work done by hitting the wooden bars with the mallet adds energy to the system at one of its natural frequencies. Tones are caused by vib
