Hello, it's nice to see you.
Wow, did last year go fast. AP-B was quite a voyage for me, and I would like to thank Mr. Powlin for leading the way in the best way possible. I learned a lot in AP-B and decided that I would like to learn more, and now here I am in Physics C.
Anyway I should probably tell you a bit about myself. I am an avid programmer, I mostly code in java and have most of my experience in the android platform. I actually programmed the revised aplusphysics app (which you ca
Almost everything in the universe has a physics principal that explains it. However a tachyon would destroy everything we know about our universe and the physics behind it.
A tachyon is a particle that travels faster than the speed of light. In doing so the particle would travel backwards in time.
So what happens when something travels faster than light? Well in terms of its physical effects, your mass would rapidly increase until it reached the speed of light where your mass would then be
Black holes, probably one of the first things many people think about when they think about space. But what is behind this matter sucker?
All the black holes we know about are singularities that are created by a super nova. As a large star starts to run out of fuel to power the nuclear reactions that keep it alive, the gravity that holds the gas of the star together starts to tear the star apart. If the gravity that holds the star is strong enough, the fuel that is left in the core of the sta
Snow, like it or hate it snow is a big part of the current landscape here in upstate New York. Although snow may seem like a luxury to others in warmer climates, the reality is that snow, a part from its appearance, makes everyday tasks 10 times harder and driving is one of the most common examples. A normal 20 minute journey can be made into an hour long ordeal with just an inch of snow. During these winter months 225,000 car crashes happen because of snow, so how can I be safe while driving in
What's this? New AP-C students?
Welp a new dawn has... dawned and I have made the short stroll of 18 miles to RIT. So what has changed? Not much.
Right now you AP-C'ers are taking, I assume, mostly college level courses and believe it or not they are actual college level classes, like no joke. With Calculus, Physics and other classes I was (and you are) taking the equivalent of a Freshman year in college. If it sounds intimidating its because it is, taking that big of a step a year early i
Recently I've been playing Kerbal Space Program. If you haven't heard about it yet it's this game where you build rocket ships and send them off into the great unknown. The thing that in unique about this game is that it has one of the most complicated physics engines I've seen in a game.
This game is very realistic, and because of this is also very complicated. In order to get in orbit of the earth is a challenge all it's self. In order for your ship to be able to escape the atmosphere it ne
Plasma balls are awesome, they look really cool, and make for some mild entertainment, but how do they create that effect we all know and love?
This globe of electricity was first discovered by Nikolai Tesla after his experimentation with high frequency currents in a sealed glass tube. He named his creation the "Inert Gas Discharge Tube." This lamp used the high voltage discharge from a Tesla coil to excite an inert gas that resided in the tube which created a streak of light.
A usual glob
If your like me, you love to play the video games, more recent games include Grand Thief Auto V. However, in most of these games guns and ammo are plentiful. Need a silenced pistol, machine gun, rocket launcher, most likely you have one on hand. But in all seriousness, how accurate is the arsenal that you carry on your back in most of these games?
Well first lets look at GTA V. In GTA a character brings an average of 4-5 guns to a heist plus ammo. If these guns include a pistol, shotgun, mach
Not much is known about Dark Matter and Dark Energy, however one explanation of these objects could be that our current understanding of gravity is horribly wrong.
These objects were first discovered by the Hubble Space Telescope in 1998. Before this time it was widely thought that the rate a which the universe was expanding was slowly decreasing from the rate at which it first started. However, as the Hubble Telescope observed supernova, it determined that the most distant had occurred 7.7 b
So the quantum world is a relatively new thing. This new world has only recently been discovered and it indeed very odd. This is because when you start to get down to individual atoms physics doesn't entirely hold up like its supposed to.
The most known phenomenon that was discovered was the fact that electrons can act like both a wave and a particle. This was found during a famous experiment call the double slit experiment. In this experiment several electrons were sent through two slits and
So many a person may be thinking, "I know what normal wind is, but what is this solar wind crap?" Well you came to the right place.
Solar wind is exactly what it sounds like, "wind" from light. Basically this phenomenon is based on the fact that the sun, or any other star, emits a stream of plasma that consists of electrons and protons traveling at very high speeds.
Recently there has been talk about figuring out how to harness this energy to create a spaceship that can travel long distanc
So by my time it is about 1 am on Monday night and I yet again find myself restless...
Of course, my mind starts to wander.
I have recently watched a TED talk by someone a few of you might know: Michael from the YouTube channel vsause (please excuse the most likely incorrect use of punctuation). Michael talks about why people ask questions and why people have been so interested in the questions he answers in his videos. This got me thinking, why do I want to learn about all this physics in the
So I have recently been playing the original Bioshock. For those of you that don't know Bioshock is a game set in the underwater city of rapture. Set in the 1960's you play the main character Jack who has just been in a plane crash in the Atlantic just off of Iceland. After the crash you find a strange lighthouse in the middle of the ocean and swim to it. Then after getting into a pod inside the lighthouse you are brought to rapture.
So how can a city exist on the bottom of the ocean?
The future of intergalactic travel may be closer than you think. Although the process may be a few hundred years down the road, some scientists believe that the starship of the future could be powered by a black hole.
As Newton's famous equation states all matter has a energy according to e = mc2. Currently the process in which we launch our rockets (burning tons of liquid and solid fuel to produce thrust) only yields under 1% of the energy that matter is capable of. This is where the black h
Cars are complex machines. The run off of the oxidation and ignition of gasoline which drives several pistons attached to a drive shaft which spins the wheels. However a certain car made by a certain company named Tesla runs entirely differently. It runs off of batteries which power an electric motor which sends power to the wheels. However if this process doesn't involve violent explosions like a gas car does, how come a few Tesla's still catch fire?
Well its all about what the batteries hav
The next processor is going to be very, very powerful.
Current processors use a series of very very small electrical "switches" to dictate one of two possible states: closed or open, or in computer speak, a 1 or 0. The computer collects these various 1s and 0s puts them in order and interprets them. This basic raw computer language is called binary and is the driving process behind all computer functions. So the more switches in a processor, the more powerful it is.
So why is the next proces
Sailing is very very old. The first representation of a sailboat was in Kuwait dating between 5000 and 5500 BC. This technology is not only old but also has some cool physics behind it.
The basic principle of sailing is as follows:
-As a boat sails across the wind the sail redirects the wind, causing the wind below the sail to be slower than the wind above the sail. This causes a low pressure system under the sail which causes lift to push the boat sideways and forwards.
-As a boat sa
Well its been a while since there has been any talk about the rovers on mars and they are still chugging along. The interesting thing about that is that one of the rovers, the opportunity rover, has just reached its ten year anniversary on the big red planet.
The opportunity rover landed on mars on January 25, 2004 to carry out a 3 month exploration of the surface. Remarkably after 10 long years the rover is still able to move and collect data along with its big brother curiosity.
Next Car Game is an early access game that is in very early alpha, so what makes it so unique? The Physics Engine.
This game is the first game to feature a soft body physics engine which makes it one of the best games to destroy things in.
So what is a soft body physics engine?
Most physics engines today don't deal too well with materials and how objects interact. Games like GTA do a relatively good job of recreating the effect of a car breaking down, but aren't able to reach a full soft bo
All this talk about mars is great but how are we going to get people to mars in a timely and efficient manor? Enter the plasma propelled rocket. Developed during the past 4 decades by Franklin Chang-Diaz, a former NASA astronaut and CEO of Ad Astra, the rocket could make it to mars in a blistering 39 days. The engine works by using radio waves to heat gasses to create plasma which then, using magnetic fields, is propelled out the back to create thrust. Because the large amount of thrust that thi
In keeping with the mars theme I found myself on the homepage of Mars One. Mars One is a privately funded expedition to mars that will transport 4 people to mars with no way back. The 15 year endeavor is currently looking for applicants from the general public to train until 2024 for the trip to mars. Anyone can apply and they are still accepting applications so if you ever wanted to be stranded on mars, now's the time. The launch of the first crew is set for 2024 along with a second crew in 202
So as my last post on black holes has seemed to gain some traction I decided to do a follow up. After a bit of research I have found out that we are all living in a lie, as it turns out, (according to Hawking) black holes don't exist.
So maybe that's not entirely true, Hawking goes on to site that the properties that have been associated with black holes may not be true. He says the fact that nothing can escape a black hole is not entirely true and that the event horizon might not actual
Just recently on the dwarf planet called Ceres a atmosphere full of water vapor has been observed. This is the first planet in our solar system besides our own to have traces of water found on it. Ceres used to be the largest asteroid in our solar system but because of its size has been named as a dwarf planet. But before you make plans for your expedition to Ceres there's one problem, its in the asteroid belt between Mars and Jupiter and its very very cold. Ceres' surface is covered in ice whic
