Look at notes from AP-B 7.) Find a friend who knows what they're doing or 8.) Teach your friends what to do 9.) Stay ahead on independent units 10.) Don't freak out and have fun
  2. The US navy has a Master Clock which is an atomic clock that sets the time standard of the DoD and the rest of the government.
  3. Faraday Cages are used to cancel out electric fields and block most forms of electromagnetic radiation. And people in today's world have used this in some creative ways. Some people put their phones in these cages so that they can't receive any calls or texts. But I was reading and this article said that a shop lifter had be caught with a bag lined with aluminum foil. This created the bag a Faraday cage so that when the person put the item they were stealing in the bag, the bag blocked most of the signal from the tag that make the sensors by the doors of stores go off when someone tries to shoplift. However this person didn't manage to get a complete cage and the alarms went off. This is just a very different application of physics than we learn in class but it's still cool

    So this summer I will be working for a company called Lumetrics which is an engineering company that develops ways to measure very thing object without ever touching said object. They do this by using light and reflection of light. This technology is currently limited to transparent and translucent material but it's still really cool. By shinning a light into an object, some of the light bounces back at the first edge, some passes through. The light that continues through hits the back edge and more is reflected back. This difference in distance travel creates a phase shift which can be used along with the index of refraction of the material to calculate the thickness. I don't really understand works but I'm sure I'll learn all about it when I start work.
  5. The greatly feared captain of the pirates "Schalkimnack" was not only famous for his cruelty but also for baffling his prisoners with difficult brain twisters. This is one of his favourite riddles: Schalkimnack took a gold coin an throw it overboard into the sea. He asked: "Did the sea level ... a) rise, sink or c) stay like before?" If one of the prisoners could solve the riddle, he was set free, but in case of giving the wrong answer, he was thrown to the sharks. Legend relates that until now, nobody could manage to solve the riddle. Now you've got caught by Schalkimnack! Can you solve the riddle? website for this riddle http://physik.ph-gmuend.de/brain-teasers/
  6. Atomic clocks are the most accurate clocks we have and without them, everyone's time could be a little off which would mean GPS navigation would be impossible and other things that rely on exact timing, like space flight wouldn't work. Most atomic clocks are made of cesium and measure the frequency of oscillation. Cesium atoms are given energy in the form of heat and this causes the atoms to change energy states and start oscillating at their principal resonance which is a know value. Measuring the resonance of the Cesium and dividing it by the principal resonance the clock can measure 1 second almost exactly
  7. Currently the only way for us to get around in space is to use rocket fuel and chemical reactions to push the rocket around. This is very expensive and current rockets are 95% fuel by weight. However NASA is developing an alternative that uses the the sun to push the rocket around. These solar sails are made with large ultra-thin mirrors that use the light of the sun to push the sail around. These sails have to be reflective because when the light hits the said it has to be reflected. This they key because thanks to DeBroglie, we know that light has momentum and as the light changes direction it exerts an impulse on the said which accelerates the sail. Granted this force is tiny compared to rocket engines, but in space the the sail will accelerate as long as it sees sunlight which means it can go much farther without fuel on board.
  8. Launch Time: 9:10am May 31st Team Members Present: All three members were there for launch but only 2 were there for the return landing Play-by-Play: Use initial rockets to break the atmosphere of Kerban, and decoupled with starter rocket, orbiting Kerban. Used secondary rockets to break orbit with Kerban and enter orbit with Duna, then broke lander off of remaining rocket. Left remaining rocket in orbit with Duna, and then landed on Duna with lander and 2 Kerbals. Had Kerbals jump around for a little bit, then reboarded the lander and took off until back in orbit with Duna. Used retrograde to push rocket and lander close together and then docked, moving Kerbals from lander to rocket. Disconnected lander, and then broke orbit with Duna, gained orbit with Kerbal, entered the atmosphere, and then landed in the ocean for a successful trip! Photographs: Time-of-Flight: 1yr 71d 21 h 50m 48s Summary: We were the First team to land on another planet and return safely. Opportunities / Learnings: We learned how to dock Strategies / Project Timeline: Next we’re going to Jool and it’s moons Milestone Awards Presented: First team to land on Duna and have a safe return.

  9. This year has gone fast. It seemed like only yesterday that summer ended and we started our senior year. This senior year has been the best year by far and now that it's almost over it's hard to realize that we're almost done. Physics this year has been a great experience. The independent units were probably my favorite units because I could do everything at my pace which was great until my pace was too slow and I found myself cramming to get everything done the last week. They have been an eye opening experience to how college is going to work because I'll have to set my own pace all the time. And even when we didn't have independent units, Mr. Fullerton taught us, but it was our responsibility to look up in book the stuff we didn't understand the first time or ask him which happened a lot more times this year than any other. Mr Fullerton might of taught us Physics for the exam, but he also taught us what we are going to have to do for college and that is probably the lesson we all will remember in the next few years.

Then the upper stage will be used to keep us in orbit around Duna while the lander will detach head down to the surface to collect samples. Then the lander will return to orbit and dock with the upper stage and will head back to Kerban. Illustrations: Safety Rep: Brendan will be approving this plan
  11. Just as a budget adjustment we had 201,581 and we got 1,000,000 for first satellite in stable orbit around a planet other than Kerbin and 180,000 for first non-Kerbin satellite (not space junk) so we now have $1,381,581.
  12. Real rockets work just the same as the model bottle rockets that we made for arts fest. Rocket engines instead of using water expel gases and the pressure that is used to expel these gases come from the burning of fuel.When the fuel is burn, the energy released increases the temperature of the gases that created when this fuel is spent. These super heated gases want to expand which causes the pressure to increase. As the pressure increases, the gases are pushed out the back end of the engine which because of Newton's third law of motion also push the rocket engine and everything attached to it in the opposite direction.
  13. A bottle rocket works because of Newton's third law of motion. As more air is pumped into the "tank" the pressure increases so that when the restraint holding the rocket in place is removed, the pressurized air forces the water out of the bottle. Newton's third law states that for every action there is an equal and opposite reaction. This means that water exerts an upward force on the bottle itself. This is what sends it into the air. A nose cone works by cutting through the air instead of the blunt bottom of the bottle forcing itself through the air which would increase drag. Fins help by stabilize the flight via air flowing over them helping keep them and the rocket in line. Finally the parachute works by increasing the drag force caused by air so much that it slows the rocket down to a speed safe for landing
  14. I would like to change my previous statement of having never seen this equation to "having only seen it once a long time ago and not remembering it at all"
  15. So I was watching an episode of the Big Bang theory and in the background of the scene i was watching was a physics equation. It said F=dP/dt which is an equation that i have never seen to before and I wondered if it was true. On the board it went on to expand the equation to F=d(mv)/dt=m*dV/dt and since dV/dt=a F=ma which is the Newton's law that we all love and know. I just thought that this was an interesting and new way to look at a very well know equation
  16. Launch Time: 9:05 Am 5/22 wed Team Members Present: Me and Mark Play-by-Play: After a perfect launc, the Eagle Dragon achieved orbit with enough fuel in the main lift off tank to get it out of Kerbin's influence. After Burn and escaping into and orbit that intersects Eve's orbit suddenly we realize that there is no encounter but it's too late. Stuck in an orbit around Kerbol scientist are forced to leave Eagle Dragon for almost 1500 day(almost 5 earth years) Finally Eagle Dragon's orbit comes close enough and the control team on Kerbin makes a burn that sends it on an intersect course with Eve. Once under Eve's influence another burn was made that keeps Eagle Dragon in orbit around Eve. After servel orbits around the planet Eagle Dragon was set on a collision course with the planet to study it's surface. Once in the Atmosphere the parachute was deployed and Eagle Dragon landed safely on the surface of Eve. Photographs: Time-of-Flight: 1492 days Summary: This taught use how to get transfer to another planet's orbit which will be necessary to get Kerbmans on other planets and back. Opportunities / Learnings: We learned that we can just launch a ship into space and hope it will intersect a planet because we can have to wait a very long time which won't be good for the Kerman's on the ship. Strategies / Project Timeline: Next we might launch a space station into orbit so that we can use it to store fuel for future expeditions. Milestone Awards Presented: First to Orbit another planet.

Design Goals: This vehicle is designed to take the satellite to another planet put it in orbit for a while and then land it on the planet to study it's the conditions on the planet. This will require more fuel than the fuel to get to the mun but we are confident that we'll have enough because the Mun satellite has plently of fuel left and as shown to us by the expedition to Mimmus with Brazanah Inc. it doesn't take that much fuel to move in space. But just in case we are adding a nuclear engine so we are fuel effiecient. Launch Goal: On this launch we are hoping to learn how to get into orbit around a different planet than Kerban. This is new because we'll have to escape Kerban which we've never done before. Pilot Plan: Fire all 3 rockets upon launch until external fuel tanks empty, then decouple the external fuel tanks, and continue to fire using the central rocket until we reach orbit with the Kerban. Then we will use the left over fuel to escape Kerban and begin on a intersect course with another planet. Once we are close to said planet we will get captured by it's gravity. After some amount of time in orbit we will deorbit and sent the satillite to the planet so that we can get gravity, temperature and pressure readings. A paracute will be use to make sure the equipement will remain intact. Illustrations: Safety Rep: Brendan
  18. Launch Time: 9:00 am on 5/17/13 Team Members Present: Mark Halecki, Andres Rivas, and Matt Herbrand Play-by-Play: Launched off of surface of Kerbal and began orbiting the planet. Then, extended orbit out to a point of intersection with Mun's orbit, where we began to orbit around Mun. Photographs: Time-of-Flight:19 hours, 40 minutes until orbit with Mun was reached Summary: We were able to break orbit with Kerbal and then regain orbit with the Mun with an unmanned space satellite. Opportunities / Learnings: How to use orbits of certain planets to intersect with other planetary bodies and achieve orbit with that other object Strategies / Project Timeline:After learning how to take orbits from close planets and use it to create an orbit with a different planet, we now plan to orbit a new planet using this same strategy.

  20. Launch Time: 1:43 Pm Wednseday Team Members Present: Just Me Matt Herbrand. Play-by-Play: At 1:43 the three rockets all fired lifting the first telecommunication satillite off into the sky. All seems to be going well until almost two minutes after launch the two external fuel cans fell off the side. At the same time two parachutes open on those tanks allowing for the tanks to be recovered. The middle rocket continues to fire until three minutes later it detaches and fall back to Kerbal with parachutes for recovery. Now the finally rocket burns for just a few seconds and it puts the satellite into a stable orbit above Kerbal thus allowing the Kerbals on the ground to make calls from just about anywhere using their new satellite. Photographs: Time-of-Flight: 8:16 Summary: This was a very successful flight because we have achieved our first orbit which will can now use to launch to other planets. Also it showed us that we need just a bit more fuel to get us into orbit so that we can reach other planets. Also we were the first to get a usefully satillite into a stable orbit around the planet Opportunities / Learnings: We learned how to get into orbit which will allow us to get to other planets like the Mun Strategies / Project Timeline: Next we are going to team with Brazannah Milestone Awards Presented: First to place a useful satillite in orbit around Kerban Available Funds: 53218

Once the fuel has been spent, the two side fuel tanks will detach and fall back to earth with parachutes so that they can be recovered. Then the middle engine will continue to fire getting the rocket high enought to maintain an orbit before detaching and falling back to earth to be recovered.

  22. Launch Time: Wednesday 5/15 at 9:43 Am Team Members Present: Just me, Matt Herbrand because my team is AWOL Play-by-Play: When the rocket fire, poor Bill Kerman was thrust upward experiences Gee forces of 2G. Riding on a tail of fire, Bill flew into the sky until all people could see from the ground was a faint light until sudenly it went out. "Oh no is this the end of Bill?" No just the fuel has been spend and now stage two has been activated. The decoupler does it's job and the spent fuel tank falls away from the cockpit and Bill countinues up. At a height of 18300m gravity finally grabs ahold of Bill's ship and he starts to fall back to the planet. At 10,000m the parachute is partial released and Bills free fall begins to slow until at 500m it fully opens slow Bill to the safe speed of 6.2m/s. 4minutes 13 seconds after launch BIll lands safely on the planet the first Kerban to reach a height of over 10,000 meters above the surface. Photographs: Time-of-Flight: 4 minutes 13 seconds Summary: In this launch we success fully got a Kerband into the upper atmosphere and back down safely. This is important because every manned flight starts and ends this way and is possibly the most important part of any mission Opportunities / Learnings: We learn how to stage different events, use decouplers, and parachutes.

  24. March has always been the worst month of the school year and this was no exception. A combination of harder classes, more homework, sports and the increasing effectiveness of seniorities turned the last week of the 3rd quarter into a cram session of trying to get everything done. Seeing how I am doing these blogs, it's clear how far behind I was and still am. This has been a rude awakening as to how much stress procrastination causes and I hope that I will be able to put off seniorities until after AP
  25. In a very recent movie, a certain character purple suited character said the line "this is what happens when an unstoppable force meets an immovable object. While in the context of the movie, there was no unstoppable force or immovable object shown, what would happen in these two things really happened. But that the just the thing because all the fundamental forces are unstoppable and there is no such thing as a immovable object according to relativity. But what would a collision between an object that we can't stop and an object that we can't move. In both these cases the object would have to have an infinite mass that way any force applied to?this object wouldn't accelerate it at all. And so when they collided since they cannot be accelerated, the only thing that could happen is that they pass right though each other. ps What movie am I talking about
