In working through the Magnetism unit, one really good question came to surface; Is it possible to have a magnet with only one pole? What would it mean to have a monopole after all?
Monopoles are essentially a theoretical particle, an isolated magnet with only one magnetic pole. This would mean that the particle would have a net magnetic charge. What would that mean in simple terms? The notion that the magnetic field has zero divergence would be proven wrong; in fact, magnetic particles would
Most of us have seen the impressive moves, martial arts techniques translated into exceptionally executed dance routines, testing the possibilities of the anatomy and mind. What is it exactly that impresses us so much about Breakdancing? How exactly is it humanly possible to maintain spins or perform moves like these?
Well Physics of course. More specifically, the use of rotational inertia and careful precision to maintain a constant velocity for a time. The physics of breakdancing moves, suc
Researchers at The University of Buffalo and Harvard University are now studying the movements of Stingrays, and how their movements can be replicated to produce more fuel efficient and agile unmanned underwater vehicles. Innovations of this magnitude would allow marine biologists and other scientists a chance to better study the depths of the ocean, and creatures living the depths we haven't explored thus far. Unmanned underwater vehicles of this nature could also assist crews in cleaning as we
Every 11 Years, the Sun's magnetic field reverses polarity, an event whose effects reach throughout the solar system, and is closely being monitored by solar physicists. While the internal mechanisms that drive the polarity shift are not entirely understood, scientists at Stanford's Solar Observatory have observed the Sun's magnetic field closely since the 1970's and can identify the initiation of the shift as it occurs on the surface of the Sun. This will be the fourth polarity shift the observ
For years, physicists and scientists have worked at this problem, a solution to the limited resources of energy we have; So just how close have we come to bringing fusion to Earth?
Well, researchers at the National Ignition Facility (NIF) have been collaborating with the Department of Energy's Lawrence Livermore National Laboratory on the project, and believe that while there is at least one (if not potentially a few) significant obstacle to achieving controlled fusion, they have overcome man
Back in 2011, there was much debate over test results that placed Neutrinos as the only particle to pass the speed of light, something thought impossible by scientists and researchers. In September of 2011, a team of particle physicists detected neutrinos moving faster than the speed of light as they traveled from CERN to the Gran Sasso Lab. The particles were said to have beaten the speed of light by 60 nanoseconds, a result that held true even with thousands of repetitions of the process.
So I've covered most of the general dynamics of the SR-71, from the engines and hybrid combustion systems to the air frame itself, and exterior structure. What more is there to cover? The potential development of an even more potent plane, the SR-72, announced as the latest project by Lockheed.
This conceptualized aircraft is an unmanned aircraft, capable of reaching Mach 6.0 speeds from standstill. The Airforce has envisioned using a similar air-breathing hypersonic propulsion system to the
So in my last post on the SR-71, I gave a general presentation on the dynamics of the engine, but what about the motherload herself? How could the frame sustain such high speeds? As it turns out, air resistance on the plane caused the exterior to reach very high temperatures, something, that if structured improperly, could mean the plane would burn up before it reached it's max speed.
The plane was made of 85% titanium, and given the expense to build such specialized parts in this metal, Lock
Hi Guys, this is one of a few blog posts I will be doing on the physics of the Lockheed SR-71 Blackbird, one of the greatest aircraft designed in the world.
The SR-71, fashioned in different types during it's commissioning, was a spy plane which succeeded the Lockheed U-2, and by all standards, it's capabilities as well. The SR-71 holds altitude and speed records, flying a max 85,069 feet above the earth's surface, and reaching speeds of Mach 3.3 (2,193.2 mph). It achieved these altitudes and
Try to picture this: We've began a war in Vietnam, and our top Weapons experts and engineers are working around the clock to create faster, stronger, more lightweight weapons that worked efficiently at accomplishing it's task. In the midst of this, the Gyrojet, a pistol named for its method of gyroscopically stabilizing it's projectiles, as opposed to the standard method of aerodynamics guns and pistols use to stabilize the bullet. This weapon was specifically unique because, instead of inert bu
Hello to all,
In having a brother to introduce me to Physics before taking the course, I knew going into AP Physics B would be a challenge, but a worthy one at that. Never did I think I would be working with 14 other very talented and intelligent students through one of the hardest AP Courses this year, Physics C.
My interests and aspirations vary greatly, from my main objective to become an Officer in the Air Force and major in Mechanical Engineering and Physics, explore combat engineerin
