Classical Mechanics

 

The study of the motion of objects at a macroscopic scale (larger than atoms) and move at speeds much slower than light

 

Physical example: Cars, Machines, People, etc

 

 

Relativity

 

A branch of modern physics (20th century) which is a study of bodies moving at speeds close to the

speed of light (300,000 km/s)

Physical example: Electrons in a high voltage vacuum tube

 

 

Thermodynamics

 

Dealing with heat, work and temperature and the statistical behaviour or systems with a large number

of particles

Physical examples: Gas/pressure cylinders, thermostats, etc

 

 

Electromagnetism

 

The study of elecricity, magnetism and electromagnetic fields.

Physical examples: Light bulbs, substations, X-Ray machines

 

 

Optics

 

The study of the behaviour of light and its interaction with materials

Physical examples: Glasses, Telescopes

 

 

Quantum Physics

 

A highly successful theory explaining the behaviour of matter at a submicroscopic level to macroscopic

observations, often covering what classical mechaics fails to explain.

All objects have a non-zero rest energy even at ground state.

Also combines the wave-particle duality of nature.

Physical example: Glow-in-the-dark material, ear thermometers, light

you're a tard

All but relativity.

 

I believe that it is possible for objects to move faster that the speed of light in a vacuum, assuming you have a vast quantity of fuel or force.

Just curious but what type of physics were used when CERN tested the Large Hadron Collider ?

It wouldn't be possible due to time acting as a frozen variable. You can't surpass it, but again this hasn't been tested at those speeds rather speeds of what is available to us.

It seems modern experiments have made relativity obsolete despite it being a more recent branch of physics.

It seems it was Atomic Physics which belongs to Quantum Physics because atoms seem to obey rules of quantum mechanics rather than classical mechanics

You're all reading it wrong.

 

It says nothing about objects already moving at the speed of light.

 

If you accelerate to the speed of light, your mass will become near infinite. Not if you're already moving at the speed of light you will not be able to go faster.

 

Stop trying to be geeks and failing half way.

 

Also : You idiots are mixing a belief system into science. These are theories, either know them or stfu.

i believe that God has created us and we must obey his 10 commandments. None of these "scientific theories" are on the commandments, or in the bible, therefore, are blasphemy.

Infinite what?

These reporters seem to be confused between the constant of 'c' (which we call the speed of light, in simplistic terms) and the speed of the phase of light waves in in a vacuum. In short, no single particle in the experiment moved faster than c.

 

In layman's terms, it's like having a line of push buttons every 1/4 mile. The fastest human can travel about 15 miles per hour. So lets say you wanted each button pressed in sequence. You could send a single person running down and press each one sequentially, or you could line up a person in front of each button, and then have each one press the button one second after each other. The problem is, that you have to run each person out their button before they can be pressed. However, as soon as that is done, they can press their buttons within 1 second of each other. So as far as the person monitoring the pressing of the buttons, it appears the same as if a single person was speeding along at 900 miles per hour, even though no person ever traveled faster than 15 miles per hour. And the setup for such an event to occur takes the same amount of time or longer to complete than if you just sent a single person in the first place, so no useful information traveled faster than the fastest speed allowed by nature.

 

This is exactly what happened in the experiment. No physical laws were broken. It was just a pretty neat trick with light waves.

 

Thus far, no experiment has outright disproven general relativity.

In fact, it has recently been proven that subatomic particles obey e=mc^2

.

 

Classical mechanics = Newtonian physics, not relativistic physics.

 

As a further note, neither General Relativity nor Quantum Mechanics work completely together. Quantum mechanics breaks down when you try to quantify gravity, or move it beyond the realm of the very small. Likewise, General Relativity behaves very nicely at medium, large, and super large scales, but becomes unwieldy at very small scales.

 

They are still both very useful tools in predicting the natural behavior of objects in the universe, but both will have to give way to a unified theory that can successfully combine both the features of GR and QM in a way that yields predictable results.

 

String theory is one such effort to unify GR and QM, but it presents no way to experimentally prove or disprove it, so many scientists in the field don't take it seriously, since the foundation of science is based on proof through experiment.

 

 

 

EDIT:

By the way, the word choice for the poll is very poor. Science is not based on belief, like religion. It is based on experiment and evidence. Science does not change based on belief. The ultimate goal of science is to predict and explain universal phenomenon through tested and documented theory.

Physics is a joke.

danny and myriad are the only ones who don't look stupid

 

in a nutshell, relativity says that space and time consist of the same material, namely spacetime. now the absolute speed limit of anything (light included) is 300000 km/s but that speed is split between your velocity through space and your 'velocity through time'

what that means is the faster you move through space, the slower you 'move through time' ie the slower you age

if you could reach the speed of light, it would require an infinite amount of energy (which is impossible) and you would cease to exist in time

 

quantum mechanics basically says everything is random chance, and particles simultaneously exist in a weighted average of all possibilities until they are interacted with or measured, and then all of those possibilities collapse into a single reality

 

quantum mechanics and relativity stop working if you use them together, like for black holes or the big bang, but nobody cares about that so only string theorists are still working on it

 

these 'theories' have never been disproved, so if you don't believe in them then you should pull your head out of your ass

I'm glad we have at least some intelligent people here...

Physics just ain't my bag, baby.

 

 

I excel in the discussions with Azide about physical chemistry, biochemistry, and what not.

why cant you believe in all of them?

why cant you believe in all of them?

 

Its impossible to believe in science. You either know it or you don't.

 

Infinite what?

 

Please explain.

MASS BECOMES INFINITE. Reread the part where I said that, it says mass becomes infinite. Infinite what you ask? If doesn't matter when its infinite you retarded fuck.

And there's much more in the background noise.

i don't understand shit and i didn't read any post in this thread but HEY i voted all of them.

quantum mechanics was a theory used to answer the questions that could not be answered by classical mechanical theory ,such as the photoelectric effect in which light showed itself to have the properties of both a wave and a particle. Scientists at the time nigger nigger nigger nigger nigger nigger nigger nigger. There are none nor will ever be good black physicists because niggers are stupid. Hitler loves you (unless you are not an honest straight pure aryan).

ELECTRO MAGNETISM MAKES ME HORNY AS FUCK!!!! :facesj:

amgad i lurv thermodynamics gibbs fwee energeeee yeeeeeee

wtf are you people on about I aint learned nuthing about this shit in school cause in year 8 I had a dyke with a mo and beard then I had another lesbian the next year and then had the head science teacher for a teacher who sucked massive dongs so I was rarely allowed in the classrom.

well he likes boy george

Jedi Pimp;598434']this is a far more interesting line of discussion. please do continue about your childhood.

 

i sense a level of hatred towards school and women who who love other women. in one sentence they are dykes, in the next they are lesbians. Perhaps you were rejected by a schoolgirl once who like another girl. Also, there seems to be some penis envy related to size....perhaps a shortcoming in your nether regions? Were you made fun of in the gym locker room by the other boys? I think perhaps we are on to something here..hence your forum name knobjockey.
