  1. Conuay Conglomerates

    Launch Report and Debrief Launch Time: 8:43 Team Members Present: Dan and Brendan Play-by-Play: We launch. Off to a good start. Straight flying. Going as planed. First detachment went smoothly. Reached 10km. reached 20km. going smoothly. 30km, 40km, and we’ve reached 50 km. starting descent. Descent going smoothly. Last detachment, just the command pod left. Back down to 30 km. deployed at 4km. landed safely. . Time-of-Flight: 7:10 Summary: We launched with the sole goal to get high in the air. We achieved this goal with flying colors. We made sure we had plenty of fuel and the resources for a safe return. Ass we got higher we lowered the throttle in order to reduce fuel use. When we used the first 3 fuel tanks we detached them and finished the mission with one. When we started to go down we detached the command pod and then launched the parachute as we got close to the ground. Opportunities / Learnings: From this launch, we learned how much fuel gets us how far. We were able to make some money, and do this launch safely. It taught us how to plan for a mission and how to put the safety of our astronauts above all else, well, except for profits. Strategies / Project Timeline: This will give us additional funds that will help us accomplish much. We hope to start orbiting by our next mission, and than soon after start exporing other celestial bodies. We should be able to continue to bring in profits and expand our organization. Milestone Awards Presented: we launched up to 10 km, the launch was manned, and we had a manned launch to over 50 km. This gives us 3 milestones accomplished in our first flight. We are the second ones to accomplish this feat so we get 50% of the reward money. Available Funds: by being the second to achieve this, we gained $15,000, but subtracting the costs of our parts leaves us with only a profit of $1,632.8. Our new total funds increases to $101,623.80.
  2. Conuay Conglomerates

    Pre-Launch Design Release Team Name: Conuay Conglomerates. Available Funds: $100,000 Vehicle Name: Krash n’ Burn Vehicle Parts List and Cost: $13,367.20 MK1 Command Pod MK16 Parachute FL-T400 Fuel Tank x3 LV-T30 Liquid Fuel Engine Tr-18A Stack Decoupler TT-70 Radial Decoupler x3 GBACC “Thumper†Solid Fuel Boosdter x3 AeroDynamic Nose Cone x3 Standard Canard Design Goals: Our Vehicle is designed to go up 50 Km into the air and return safely to the ground. To achieve this we are making sure our vehicle has the proper engines and fuel tanks to reach that height. Then we have many detachable parts and a parachute to ensure safe landing. Launch Goal: WE are hoping to learn how much resources are consumed to get to heigher heigts, and what parts work the best for flying. Pilot Plan: The pilot will just be keeping the spaceship straight to make sure it gets the highest height with the least displacement.
  3. Optical illusions

    Many of us enjoy looking at optical illusions, but why do our eyes lie to us????? Although each illusion has it's own reason, and scientists still don't know all the reasons, it comes down to one thing. Our brain makes assumptions. Our brain uses context of our surroundings to make split second assumptions. This is helpful in everyday life and back when we were hunters and gatherers and needed to make split second decisions in the wild. Our eyes don't show us what's really there just what we need to see. It uses the surrounding environment to make conclusions. This is done by using shadows, surrounding colors, and past experiences. optical illusions are just a case of your brain telling you what you should be seeing, not what is actually there.
  4. 2D Reubans tube.

    In physics you learn about waves. However, many people don't realize that waves are every where. A rubens tube is a tube with natural gas pumped through it with holes in the top. when a steady vibration is used on the tube, a standing wave is formed. It has nodes and anti nodes like any wave. When you put a lot of vibrations through, like say music, the effect is very cool. Most rubens tubes are just a linear single tube, in this video however, it goes into 2 dimensions the result is amazing.
  5. Water and Sound

    The video below shows a very cool experiment. It shows how the flow of water changes when a vibration is applied. water reacts very strangely when it is vibrated. enjoy
  6. Resonance

    Many cultures and spiritual factions speak of the importance of frequencies and vibrations. many cultures believe it plays an important role in nature. Certain frequencies create geometric shapes as the frequency increases, the patterns get more complex.
  7. Lift Forces

    A fluid that flows past a surface of a body exerts a force on it. Lift is the perpendicular component to the oncoming flow, of this force. It is the opposite of a drag force. Aerodynamic lift is different from other kinds of lift. Aerodynamic lift requires relative motion of the fluid. It usually refers to when an object is completely immersed in a fluid. Lift is what makes it possible for a plane to fly. Lift is also used in Frisbees. As man takes to the sky, we owe much to the power of lift forces.
  8. When people think of the light bulb, they just think of Edison. That is not the case. in 1802, Humphry Davy created the first electric light. He heated carbon with a battery until it started to glow. This was known as the electric arc lamp. This invention didn't work because it didn't last very long and was just too bright for an practical uses. In 1840, Warren de la Rue enclosed a coiled platinum filament in a vacuum tube and passed an electric current through it. The design was based on the fact that the height melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain fewer gas molecules to react with the platinum. Although this was an efficient design, the high cost of platinum prevented it's use in the commercial market. In 1850, Joseph Wilson Swan enclosed carbonized paper filaments in an evacuated glass bulb, but the lack of a good vacuum and adequate supply of electricity resulted in an ineffective producer of light. There were many variations of a light emitting device before Edison, but he was the first to make a commercially viable model. Since there have been many different models, and there will continue to be changes in the future.
  9. Skyrim is one of My favorite games ever. There is a lot of good physics in the game, but that's not nearly as fun as the bad physics. This is what happens when physics goes wrong.
  10. What is Plasma?

    Plasma is one of the four states of matter. You have plasma in your light bulbs, TV's, and the sun. Plasma is created by ionization. A gas is heated or put in a magnetic field. Plasma is a good conductor and therefore has a very small electric field. Plasma is the most common state of matter in the universe. It is a very important pat in the fusion of light atoms. Plasma is often confined to a small region for fusion to take place in reactors. Plasma is a key part of solving the energy crisis we are facing. Plasma is vital to the universe and is very important to us as humans. Plasma is often neglected by most people and that's not fair. Appreciate plasma.
  11. Continuing, another important part of the game is the weaponry. To start, there is a weopan class called fusion rifles. The game offers no insight into how these guns work but the only assumption I can draw is that it has something to do with fusion. My theory is that there is some sort of nuclear energy generated by fusion and is somehow controlled and then fired from the wopen. There would be a lot of physics in the charging/splitting of atoms all in a short a series of short bursts. There is also less exciting physics. For example there is a ton of projectile motion with the throwing of grenades or bullets. Also their is recoil in the guns. In this game you are a guardian, so I'd assume you are stronger than average but the odds are that there will still be recoil in the gun as a counter reaction of the projectile being launched (unless it's the ACR from MW2). All in all, physics wise this is a pretty solid game. However, the story line is very week, the gameplay is repetitive, and the online can be pretty aggravating at times. That being said, Peter Dinklage is one of the voice actors, so you should buy this game.
  12. Destiny is a video game devolved by the company Bungie. Bungie has experience with theoretical physics after they made the Halo series. Destiny is one of the most expensive games ever made, which brings up an important question. Did they do a good job? The first thing to look at is the little details. The capes the shadows, the lighting, and so on. In this, in my opinion, they did a good job. The game looks and feels fantastic. There are many flaws with this game, but all in all, they did a good job on the little things. The little physics is easy to miss but helps move the game along seamlessly. Another aspect of the game is the sparrow. The sparrow is essentially a hover bike. We do not have one of these yet so I can't say how accurate they were on it. However, it looks and feels exactly how you think one would. It has propulsion on the back. Using Newtons laws it propels itself forward and uses Newtons laws somehow to keep it above the ground.
  13. Golf Swing

    A golf swing is much like a slap shot in hockey. A good golf swing is vital in the game of golf. A golf swing is almost all rotational energy. A higher velocity means more rotational energy. The more energy in your swing leads to more energy transferred to the golf ball. The more energy you can transfer to ball the farther it will go. The angle at which the club hits the ball is also important. You want the face of the club to be completely flat when it comes into contact with the ball. If it makes contact at an angle, it will cause the ball to spin. The spin of the ball causes friction with the air resistance causing the ball to bend, and the ball will slice. This is much like how soccer players are able to bend the balls on shots and free kicks. The club is like the players leg, and the soccer ball is the golf ball.
  14. Slap Shot

    Hockey is a fast paced sport full of physics. A prime example is the slap shot. The slap shot is basically a large rotational force. The player is rotating his body and uses the stick as essentially an extension of his body. You can calculate the force by finding the impulse on the puck. http://www.youtube.com/watch?v=bcielx6_ArQ This is a video of Zedeno Chara at the 2012 all star competition By simple physics equations, we can find out that his stick is rotation at 12.4 radians per second! That's pretty amazing we also can find out that chara was able to bow his stick almost an inch. That creates a huge buildup of potential energy that snaps on the puck causing it to reach these high speeds!
  15. Guitar(acoustic)

    Acoustic guitars work a lot like electric guitars and basses(see previous blog posts). They have six strings. The note the string plays depends on the frequency. The frequency depends on the length, mass and tension of the string. So that means that you'll have to tune and string your guitar differently depending on what strings you use. When you play a note, the strings vibrate and produce a sound. The note produced depends on the frequency. This is pretty much universal in all string instruments. You can alter this by changing the length, so pressing down on the frets, the tension, use the tuning pegs, or the mass, by using a completely different string. I would recommend the first two options and not going to but a new string every time you tune your guitar. However, the acoustic guitar has something that an electric guitar doesn't and that's a vibrating top plate. the vibrating top plate creates an air cavity resonance that will amplify the sound of the strings. the vibration of the strings gets to the bridge and the vibration of the bridge is what causes the top plate to vibrate. The air cavity resonance can be affected by a lot of factors including the type of wood, as well as the size of the body and the hole. Antonio de Torres Jurado created a style of strutting that has the struts diverge from the sound hole on the top plate, creating a more sustained tone.
