    Physics in MINECRAFT

    Interesting post... I was talking on Wednesday night with a physics professor and author (Rhett Allain) as well as other physics teachers about the physics of video games. Part of our discussion centered around the accuracy of the physics in these games -- and how close to real life much of video game physics is. Even the old-school Atari game "Asteroids" had pretty good physics (OK, the ship had SOME friction in space, but in general, the game was all about Newton's Laws of Motion). Mario Brothers and Donkey Kong have some weird gravity and jumps, but for the most part, the better-selling games are typically quite accurate. For more information on this topic, check out Allain's post about the Physics of Angry Birds or his new e-book on introductory physics, Just Enough Physics, available for $3.14 (Pi dollars) on Amazon (see review in previous post here).

    15 Min of Fame

    Thanks, and congratulations on both a successful launch and a successful "15 Minutes of Fame" assignment presentation!

    We Have Lift-Off...

    That's quite the launch velocity... sounds like a terrific event!
  4. Way to tie together modern events, physics, and Big Bang Theory! You can check out willorn's post here.
  5. [ATTACH=CONFIG]144[/ATTACH]For those anticipating the upcoming Regents Physics exam on June 15th, APlusPhysics: Your Guide to Regents Physics Essentials is a book designed to give you everything you need to score well on the exam in a simple, easy-to-read manner. Filled with sample problems and full solutions, the book is now only $10.07 from Amazon!
  6. [ATTACH=CONFIG]142[/ATTACH]Prof. Allain has taken his Dot.Physics introductory blog posts and formed them into a fun and entertaining e-book covering the basic principles of mechanics. From his initial advice not to use the e-book as a table leg prop to his discussion of differential equations in chapter 15, Just Enough Physics provides students a light, simple, and concise explanation of algebra-based physics. Further, Just Enough Physics actually includes directions on basic VPython programming for simple physics simulations… if you’re like me and have been reticent to dive into simulation and programming, this text provides several code snippets with clear explanations that entice you to see what you can do by way of numerical simulation and computer modeling. As a high physics teacher and engineering professor, I highly recommend this book for beginning physics students of any age.
  7. I have a superconductor, a neodymium magnet, and a dewar to hold liquid nitrogen -- let's play with this next week!
  8. Great analysis willorn... can you elaborate on the centripetal force is caused by in your problem?
  9. Hi! I'm FizziksGuy (aka Mr. Fullerton), a physics teacher at Irondequoit High School in Rochester, NY. I have the best job in the world, teaching terrific students a subject I'm very interested in, and this past year wrote a book to help students do well in introductory physics, titled APlusPhysics: Your Guide to Regents Physics Essentials. Outside of school, I enjoy spending time with my wife, two wonderful energetic daughters, and my exhausted dog. Hobbies and interests include volleyball, piano, guitar, and I'm a bit of a major league baseball junkie. Welcome to APlusPhysics.com -- I hope you find this site a useful and fun addition to your physics resource arsenal!
  10. Terrific short video about light, sound, and the Doppler Effect:
  11. [ATTACH=CONFIG]125[/ATTACH]The first APlusPhysics course guide book, APlusPhysics: Your Guide to Regents Physics Essentials, by Dan Fullerton (aka FizziksGuy) is now available for direct order, and will be available in early May from major book retailers such as Amazon.com and Barnes and Noble. From the book's description: APlusPhysics: Your Guide to Regents Physics Essentials by Dan Fullerton is a clear and concise roadmap to the entire New York State Regents Physics curriculum, preparing students for success in their high school physics class as well as review for high marks on the Regents Physics Exam. Topics covered include pre-requisite math and trigonometry; kinematics; forces; Newton's Laws of Motion, circular motion and gravity; impulse and momentum; work, energy, and power; electrostatics; electric circuits; magnetism; waves; optics; and modern physics. Featuring more than four hundred questions with worked out solutions and detailed illustrations, this book is integrated with the APlusPhysics.com website, which includes online question and answer forums, videos, animations, and supplemental problems to help you master Regents Physics essentials. Advance Praise for APlusPhysics Regents Physics Essentials: "Very well written... simple, clear engaging and accessible. You hit a grand slam with this review book." -- Anthony, NY Regents Physics Teacher. "Does a great job giving students what they need to know. The value provided is amazing." -- Tom, NY Regents Physics Teacher. "This was tremendous preparation for my physics test. I love the detailed problem solutions." -- Jenny, NY Regents Physics Student. "Regents Physics Essentials has all the information you could ever need and is much easier to understand than many other textbooks... it is an excellent review tool and is truly written for students." -- Cat, NY Regents Physics Student
  12. It's official, you can now purchase the book through direct order. For the next few weeks, use discount code "RS74P4XQ" at checkout to get a reduced price of $12.59!!!

    Mature Black Hole

    Very cool goNavy51... I'm always amazed to realize that despite all we know (or think we know), the amount that we don't is tremendously greater. Check out the "Top 10 Strangest Things in Space" for more weirdness!
  14. Glad you got it sorted out... have a great weekend!
  15. Hi Keri -- the .01 (or .05 in your case) didn't go away, I just multiplied it in with the permittivity of free space. Sounds like you're on the right track... if you're still stuck, post the actual problem and we'll take a look at it!

  17. Sure... tell us more about the problem, but in general, the easiest way to complete a combination circuit is to find the equivalent resistance for all of your resistors in parallel, and simplify the circuit with equivalent resistances until it looks like a basic series circuit. Then, you can find the current flow and voltage drops across the various parts of the circuit, which will then help you fill in your original, more complex circuit.
  18. Dr. Ben Kilminster, head of the Higgs Boson project at Fermilab, visited us last year and was interviewed about his work as part of the Physics in Action podcast. Check it out! http://www.aplusphysics.com/podcasts/PIA/PIA_Ep012_FHockeyKilm.m4v
  19. Great Introduction from Electromagnetism to Modern Physics! http://www.nasa.gov/mission_pages/GLAST/news/fermi-thunderstorms.html
  20. Hmmm, not able to take a look as I don't have a NY Times login... perhaps we can find this somewhere else.
  21. Very cool -- yes. And gotta love her duds... but this is another Moog Music April Fool's joke: http://www.wired.com/underwire/2011/04/polyphonic-theremin/
  22. Great insight into the physics of the sweet spot and waves... not so sure about the Yankees pitching this year, though...
  23. Some of those look pretty painful!
  24. Wow, never thought my MacGyver Magnetostriction video would gain an audience! Now to put a video together on superconducting magnetic levitation...
