You know the yogscast are a minecraft player like you and have every right to criticize what mojang puts out in the next update. Maybe we should start getting mad at you because you don't like every feature.
I hate how people generalize about a wide mass of people. You do realize CaptainSparkles is a member of the yogscast... So by calling the yogscast bad you have just called CaptainSparkles bad.
^ Exactly why you shouldn't generalize.
The yogscast are popular because they are funny and I love to kick back and watch some MoonQuest or Garry's Mod and have a laugh.
The yogscast are very talented and work hours everyday to put out good content.
Also, why do you think a petition is gonna make them just drop everything their doing and go to being homeless? (This is their full-time job)

Oct 7, 2013The thief and the car owner should be tried separately with not a single thought about the other's crime brought up.Posted in: Politics, Philosophy, News and Science
I think the car owner should be punished for assault because he purposely planted a poison inside the car, this isn't itching powder, this is real poison and should be treated like so.
The thief should be treated as if he did nothing because INNOCENT UNTIL PROVEN GUILTY.
He was not in threat of bodily harm so he cannot use physical force (ANY)
This is like if your neighbor accidentally drove a foot or 2 across the property line with his mower and then you shot a stun gun at him. Then you said "but he destroyed part of my property, my grass!"
Jul 5, 2013LOL favoritism much? this is the MINECRAFT forums, i guess you gotta do a announcment for every voxel based game, comon we need a starmade announcment too.Posted in: Minecraft News
I SWEAR THIS IS THE MINECRAFT FORUMS you are a mod and you don't even follow your own rules! that is like a police officer breaking the law.....

May 21, 2013I really wish the golden days of NASA were back. I call the "golden age" the 15-year period of 1957-1972. I mean, sending rovers to Mars is cool & all but we need to send someone atleast back to the Moon to kick up PR.Posted in: Politics, Philosophy, News and Science
After we have generated enough PR we could harness that to take the steps towards a Mars mission. We would still have to do missions in between that would keep the PR high enough. It is not commonly known that by Apollo 11 the program was running on fumes.
What Nasa needs, is a second space race. Or a complete reboot and/or a kick up in budget.
Currently, Nasa gets 0.5% of the US's budget. To get manned space flight on a roll we need to bump up the budget to atleast 1% or even better a whopping 2%!
The amount of money spent on defense now is about ~5%. So if we could just make that ~4.5% we would be finally sending people back into space again!
Some countries only spend as little as 1.5% on their military!
Lets go back to the "Final Frontier"!
(The reason i am not suggesting more rovers is because, Curiosity for example, moves at a whopping 1.5 INCHES per second! )
So i guess i can spark a discussion with this, so discuss away!
May 13, 2013I've been wondering about nuclear power, it has less deaths per trillion kilo watts than even wind. Whats with the stigma against it? It's clean, safe, its the energy of the future.

I am not a hater of obama i just hate what the U.S is doing. The president should go formally apologize to the familes of at least the children that were lost in the "war on terror"
AAAAAAnd im still waiting for Bin Laden's "Fair Trial".
P.S. When it comes to terrorism, it is extremely racist towards middle-easterns, when have i seen a white, american arrested as a suspect for a terrorist attack? Please link it. As a result of a long investigation, not easily figured out like Sandy Hook.

The purpose of this experiment is to explore the physics surrounding minecarts. I did experiments to test if collisions are elastic or inelastic, to test if momentum is conserved in collisions, and to determine the coefficient of kinetic friction for minecarts.
One of the first things students do in physics class is roll carts down tracks to learn about energy and momentum. This experiment will do the same, but with minecarts. To determine how similar or different minecart physics are from real life, I will conduct several experiments with minecarts. I will test to see if collisions are elastic or inelastic, to determine if our current momentum laws are valid in Minecraft, and to determine the coefficient of kinetic friction for minecarts.
Materials and Methods
The first experiment will determine whether minecart collisions are elastic or inelastic. An elastic collision is a collision in which the two objects bounce apart after colliding, like a rubber ball bouncing off of a wall. An inelastic collision is the opposite, the two objects stick together, like play-doh sticking to a wall after colliding. To determine this, I placed a minecart above a sloped track, and a minecart at the bottom of the sloped track. Because occupied minecarts behave differently than unoccupied minecarts, I placed a zombie in each minecart to make them occupied. I recorded the experiment. You may watch the video . As is evident in the video, the two carts stick together after colliding. This means that the collisions are inelastic.
The next experiment will test if our momentum laws are true for Minecraft. In inelastic collisions, momentum (p) is conserved. This means that:
p1 + p2 = p3
Or the momentum of the carts after they collide is equal to the momentum of the first cart plus the momentum of the second cart before collision. Momentum is defined as mass times velocity. This relationship is shown in the equation for momentum:
p = m * v
So, the first equation can be rewritten like this:
m1 * v1 + m2 * v2 = m3 * v3
Now, in Minecraft, it is impossible to measure the mass of an occupied minecart, at least in conventional units. However, it is not necessary to do so. As long as both minecarts have the same mass, it is simply a matter of ratios. I will give each cart a mass of 1 minecart (1mc). To prove if the above equation works, I will perform a similar experiment to the first one, but with myself in the minecart above the slope in order to measure the velocity of the minecart before and after the collision. The other minecart will contain a zombie. Because the minecarts do not contain the same entity, it is questionable if they have the same mass. I tested this by setting up two minecart tracks similar to the track from the first experiment side by side. I put a minecart containing a zombie at the top of the hill and another minecart containing myself at the top of the hill on the other track. I positioned 2 pistons behind the minecarts connected to a button in order that both minecarts are pushed off at exactly the same time with exactly the same velocity. If the two minecarts have the same mass, they will travel along the track at identical speeds. I recorded this experiment. You may watch the video . As the video shows, the zombie and I traveled at exactly the same velocity down the track. This means that both minecarts had the same mass.
Now that I have determined that a minecart with a zombie and a minecart with a human have the same mass, I can conduct the actual experiment. I will determine the minecart's velocity the instant before collision and 1 second after collision by using F3 and frame analysis. The minecart's velocity before impact was 10.308 m/s and the velocity after impact was 4.8741 m/s. I will solve for v3 in the momentum equation and compare that velocity to the recorded velocity.
m1 * v1 + m2 * v2 = m3 * v3
1 mc * 10.308 m/s + 1 mc * 0 m/s = 2 mc * v3
10.308 m/s = 2v3
v3 = 5.154 m/s
5.154 m/s seems very close to 4.8741 m/s. I will calculate percent error.
(abs(4.8741 - 5.154) / 5.154) * 100 = 5.43%
A 5.43% error is very reasonable. Because there was a small percent error between the theoretical velocity and the actual velocity, I can conclude that the law of conservation of momentum does apply to minecarts in Minecraft.
The final experiment will be to determine the coefficient of kinetic friction between the minecart and the rail. The coefficient of kinetic friction determines the force of friction on the minecart. The force of friction is equal to the coefficient of kinetic friction times the normal force, which is the force exerted by the ground on the minecart. The formula for coefficient of kinetic friction is:
µk = Fµ / Fn
In this equation, µk is the coefficient of kinetic friction, Fµ is the force of friction, and Fn is the normal force. Since Fµ and Fn are both forces, and since F = m * a, the equation can be rewritten as:
µk = (m * aµ)/(m * ag)
In this equation, aµ is the acceleration caused by friction, and ag is the acceleration caused by gravity, and m is the mass. Since mass is divided by mass, they cancel, and leave us:
µk = aµ/ag
In my last paper, Mass of the Minecraft Earth, I determined that the acceleration due to gravity was 14.4622 m/s2. Thus, the equation now becomes:
µk = aµ/14.4622 m/s2
The only unknown besides µk is aµ. This can be found by comparing the velocities of a minecart 1 second apart. I chose a part of my video where there was an uninterrupted second of traveling over the flat track. At the point I chose, the minecart had a velocity of 7.2729 m/s. 1 second later, the minecart had a velocity of 7.1271 m/s. This equation can be used to calculate acceleration:
vf = vo + a * t
In this equation, vf is final velocity, vo is original velocity, a is acceleration, and t is time. I will substitute the known values into the equation.
7.1271 m/s = 7.2729 m/s + a * 1 s
7.1271 m/s = 7.2729 m/s + a
a = -0.1458 m/s2
Now that we have aµ, we can substitute this into our equation.
µk = -0.1458 / 14.4622
µk = -0.010081453721
I would note that µk is a scalar quantity, so I will drop the negative sign and round to a more reasonable value.
µk = 0.01
This means that to calculate the force of kinetic friction on a minecart, you can use:
Fµ = 0.01 * Fn
The results of these experiments are that occupied minecarts have inelastic collisions, the law of conservation of momentum is true for inelastic collisions between occupied minecarts, and the coefficient of kinetic friction for an occupied minecart is 0.01.
Firstly, I will cover sources of error. There is only one source, and that is inexact frame capture. Basically, my recording software probably did not capture frames exactly when events occured. You can see the effect of this if the difference between theoretical velocity and actual velocity in the conservation of momentum experiment. This would have affected the conservation of momentum experiment and the coefficient of kinetic friction experiment. This is unavoidable.
Now, I will discuss the results. I was surprised to learn that minecarts have inelastic collisions. I was expecting for them to have elastic collisions, as most "carts" do in the real world. If they did have an elastic collision, the cart pushed off the hill would have stopped, and the other cart would have shot off at the same speed that the first cart was going before the collision, just like a Newton's cradle. However, they very clearly stuck together, so the collision was inelastic. I was also excited to find out that conservation of momentum was true for Minecraft. While recording the video, I did not notice the drop in velocity, so I was expecting it to not apply. I was shocked and delighted to discover that the velocity had been halved.
There are no conclusions that can be drawn from these results other than those already found. This paper is more of a report of findings than a study to be ruminated on, as my last paper was. However, these findings will be extremely useful for future calculations involving minecarts.

If you're trying to aggravate me, you're doing a remarkable job. What you're doing right now is looking the most vulnerable and hurt members of society, spitting in their face and punching them in the chest whilst laughing at them. I can only hope that you never assume a position of influence over anybody.
The point is that any thoughts of suicide are irrational. People who think about it are being irrational when they do so. They don't realize the ways in which they're being irrational, so they're going to make stupid mistakes without realizing just how stupid they're being. The way to fix that isn't to throw a pity party about how horrible their life is like you seem to want to do. That will justify their stupid belief. That will make that behavior stronger.
Yeah, if I want depressed people to commit suicide, then I'll have them talk to you so you can convince them that they're actually going through an extraordinary amount of pain, that there's nothing they can do about it, and that nobody could possibly relate to them. If I want them to become healthy people again, however, I'll try to break the illusions they hold.
