  1. Quarter Review

    At the end of last quarter, I wrote a blog post about how I needed to change a few things because of the disaster that had come about in all my classes but especially physics. I feel that over the course of the past 10 weeks, I have changed the way that I learn and study. I find that I am more focused to get things done and understand them in a timely manner. I use all of the time given to me efficiently as well. Before this quarter, I found myself wasting class time and not doing the work that I needed to do in order to understand the content. Now that the learning is almost done for most classes and we move into the studying for exams during the last quarter, I need to remember the success that I have had during this quarter and continue it on. I know I can do it. We are now in the final stretch of high school and I am ready for it all. Until next time, RK
  2. Cell Phones

    Something I have always wondered is the way in which a cell phone works. Everyone has them in today's world so now I need an explanation to how they work in a physics sense. From what I understand, when someone talks into the phone, their voice is converted into a signal that is transmitted through waves and then back into sound on the other end. Essentially it sounds like a two way radio. The signal is a type of radio wave that in the end can be dangerous to humans resulting in various health issues in the long run. Are cell phones really worth it if we are exposed to even more radiation that we need to be? Until next time, RK
  3. Waves

    Earlier this year, we learned that physics is everywhere. I think that most of us have realized that physics comes up in our daily lives on earth and also in space. One area that I have forgotten about when in comes to physics is how physics relates in the oceans. One major idea is the waves in the ocean that we can hear about. The high tides and low tides impact the shells that we can find on the beaches. Because of gravity and the moon, the tides are on a cycle for high and low tides. The waves that formed through energy moving through the matter of water onto land. The picture below shows how the waves are used in surfing (something that I will never do in my lifetime). It uses that basics of waves that we learned about last year and puts them into the water all over the earth. Until next time, RK
  4. Fire in Space

    We all know what a candle looks like when we burn it. The blue at the bottom is the heavier and cooler fire. Because of gravity, the blue is at the bottom while the hotter and lighter fire is towards the top. On earth, fire burns up and around and spreads because of the oxygen that it has access to. In space, because there is no gravity and a very low concentration of oxygen, fire burns in spheres and spreads quickly based on where it can get the oxygen. In the video below, fire in space is explained in further depth with baffling information about combustion as well. Until next time, RK
  5. The Bermuda Triangle

    Many people know about the infamous Bermuda Triangle because of the ships, planes and people that all go missing in the triangle. The Bermuda Triangle spans from the edge of Florida to Bermuda and then down to Puerto Rico. The disappearances that come about from the triangle are unexplained and this is not something new. In 1492, Christopher Columbus made note in a journal that his compass was not pointing north but decided not to alert the already worried crew. Some evidence has proven that in the triangle, there are certain areas that a magnetic compass will point towards true north instead of magnetic north. In addition to the changing compass, the weather in The Bermuda Triangle has reportedly been another crazy factor in this equation. Because of its location, weather can dramatically change over a short period of time. These weather changes have also been known to become violent which could add to some disappearances. There are still no actual explanation to the vanishing boats, planes and people in The Bermuda Triangle, but one thing is for sure, something fishy happens down there. Until next time, RK
  6. Flying Birds

    We all know that birds fly except penguins but they waddle which is better than flying. To fly, a bird must flap its wings to give it lift that is greater than its weight in order to get up off the ground. If the lift is not greater than the weight, the bird will sit there flapping its wings and look like a crazy bird. Another aspect that remains in the mix for all flying birds is the drag forces that go along with their flight. To fly to their destination quickly, a bird wants to minimize drag forces if possible. Drag forces can be a burden for all flying birds sometimes, but on the other hand, when slowing down to land, a bird likes the drag forces because they will help the bird land quickly and without injury. The statements above apply to all large and small flying birds. For larger birds, they often soar throughout the sky to save energy. This happens because they have larger wing spans that allow them to flap less to get the same amount of lift as a smaller bird. Now as for the penguins that waddle, they use their feet to shuffle along and stay on the ground. Until next time, RK
  7. Buoyancy

    Buoyancy is the upward force that is exerted opposite to gravity with a liquid. In the diagram below, buoyancy is shown acting against gravity keeping up with the laws of Sir Isaac Newton. Buoyancy is the reasons some objects float on the water and some objects sink. Because it is spring break and I am on vacation by the ocean, I thought it was fitting to look into buoyancy. A rock sinks right to the bottom while boats and kayaks float on top of the water. The video below shows how extreme people who kayak work the waters using buoyancy. Although I did not go kayaking, I watched those who did. They did not go to the extreme that the Olympic teams do, but they still had buoyancy on their side. The boats that we went on to dolphin watch were more like the one in the picture below. It still amazes me that a large amount of people can travel on a boat without the boat sinking or tipping. Until next time, RK
  8. Maglev Monorails

    Most people know what a monorail is but what is a Maglev Monorail? Maglev means the transportation system levitates and moves using extremely strong magnets. Maglev Monorails operate using the strong magnets to move the train that has no wheels. The whole concept that the magnets repel their like sides and attract to their opposites help to push the monorail to top speeds. In the United States there is a Maglev Monorail in California at General Atomics in San Francisco. Below is a video of a brief news reports on the Maglev Monorail in China when it completed its test run. Until next time, RK
  9. Luge

    I have never heard of the word "luge" until today when looking at events in the Winter Olympics. Luge is a sport where there is a rider on a sled that is sliding down ice feet first. The objective is to get down the track in the fastest amount of time. They often look like this while racing... The rider has to fight air resistance to get down the track as fast as possible. They start at the top of an ramp and then have to go around turns until they reach the finish line. Although this may not seem like a dangerous sport, riders can reach speeds of 95 mph or more. In the 2010 Winter Olympics, rider Nodar Kumaritashvili died in a practice run hours before the opening ceremony. Because of his high speed, he flew off his sled into the air and hit a metal pole. Due to his death, track designers for the 2014 Winter Olympics designed a track that went uphill in some areas which would force riders into slower speeds. Riders rely on gravity and proper turn times to reach the finish line the fastest. Until next time, RK
  10. Will Physics Pay Off?

    So, most of us in Physics C have reached a point where we start to think about college and how this class is going to help us in the future. From what I have heard, most of us in this class plan on going into something that relates to physics in some way whether it be engineering or just a normal physics major. In the classroom, there is a poster that has the 10-Best Paying Majors on it which sparked my idea for this post. In other math and science classrooms you can see posters like this one that try to keep people involved in these classes. STEM classes have components that are in the top paying jobs overall. More recent information says that the order of top paying jobs include a lot of engineering which includes a lot of physics. 10. Geological and geophysical engineering 9. Computer engineering 8. Mechanical engineering 7. Aerospace engineering 6. Electrical engineering 5. Chemical engineering 4. Mining and mineral engineering 3. Metallurgical engineering 2. Pharmaceutical sciences and administration 1. Petroleum engineering As I think about how hard this class has become, I realize that it will somehow help me in the future even if it just for the challenge of it. Until next time, RK
  11. Christmas Physics

    I like to still believe that there is a Santa out there but everyone tells me it is absolutely impossible
  12. Vinny Bray's Fancy Flips

    I hope he can do all of that and beat the school record this year!!!
  13. Winter Physics 2018-2: Ice Skating

    That looks like it takes a lot of skill! Definitely not something that I could do!
  14. I wouldn't want to be hit by either but maybe you could get some money out of the person that owns the Lamborghini and hits you
  15. Let's Talk About Webassign

    I think you should talk to the people who run Webassign! We need an app!
