Primarily, because that's what I was taught,
and arguing about being a sheep is non-sequiter,
the government teaches us that cancer kills people, yes?

and every bit of literature and personal experience
has backed up this claim. such as gravity, magnetic field of
the earth, flight paths, seasons, etc.

BUT all of this can be and of course has been refuted by the FET.
And most of your arguments are at least possible due to the fact that
locally a sphere resembles a disk, so FET will make sense as long as
numerical evidence is not shown.

The point where I see FET break down is in the fundamental differences
between a sphere and a disk. This difference lies not in the properties of
geology and astronomy, but in topology: all of the vectors normal (perpendicular) to a disk are
parallel and all of the vectors normal to a sphere are radial. therefore, you can prove the normal
vectors to be non perpendicular, you can show that the earth is a sphere.

you can show this, by computing surface integrals, or surface vectors, because the cross-product of which
will give you the normal vector. now, according to FET, these normal vectors should be identical, so therefore
arbitrary surface integrals should be the same.

but they are not equal at all, as you cannot see america from Everest.

We still do not know what electricity is: electricity are the electrons of the atoms moving in the oposit direction of the powerligne

1.Not always.

electrons are little masses of pure energy

2. What does this even mean? If you mean that electrons have mass and energy, then congratulations Einstein, you've identified two of their three most basic properties. Also, it doesn't make sense to talk about something as being "pure energy", because it implies that you can somehow obtain impure energy.

Some people believe the Earth is hollow: not true

3. How do you know? Have you asked everybody in the world whether or not they believe the Earth to be hollow?

1. ok, when not (could be that i'm wrong, but so far i know, i haven't met an other situation)
2. ok: an article is one of the smallest elementary particles, it has a negative charge and as far as we know, it doesn't exist out of anything 'smaller' (or however you say it in english)
or:

An electron is a subatomic particle that carries a negative electric charge. It has no known substructure and is believed to be a point particle.[2] An electron has a mass that is approximately 1836 times less than that of the proton.[8] The intrinsic angular momentum (spin) of the electron is a half integer value of 1/2, which means that it is a fermion. The anti-particle of the electron is called the positron, which is identical to the electron except that it carries electrical and other charges of the opposite sign. When an electron collides with a positron, they annihilate, producing a pair (or more) of gamma ray photons. Electrons, which belong to the first generation of the lepton particle family,[9] participate in gravitational, electromagnetic and weak interactions.[10] Electrons have quantum mechanical properties of both a particle and a wave, so they can collide with other particles and be diffracted like light. Since an electron is a fermion, no two electrons can occupy the same quantum state, a property known as the Pauli exclusion principle.[9]

The concept of an indivisible amount of electric charge was theorized to explain the chemical properties of atoms, beginning in 1838 by British natural philosopher Richard Laming;[4] the name electron was introduced for this charge in 1894 by Irish physicist George Johnstone Stoney. The electron was identified as a particle in 1897 by J. J. Thomson and his team of British physicists.[6][11]

In many physical phenomena, such as electricity, magnetism, and thermal conductivity, electrons play an essential role. An electron generates a magnetic field while moving, and it is deflected by external magnetic fields. When an electron is accelerated, it can absorb or radiate energy in the form of photons. Electrons, together with atomic nuclei made of protons and neutrons, make up atoms. However, electrons contribute less than 0.06% to an atom's total mass. The attractive Coulomb force between an electron and a proton causes electrons to be bound into atoms. The exchange or sharing of the electrons between two or more atoms is the main cause of chemical bonding.[12]

According to theory, most of the electrons in the universe were created in the big bang, but may also be created through beta decay of Radioactive isotopes and in high-energy collisions, for instance, when cosmic rays enter the atmosphere. Electrons may be destroyed through annihilation with positrons, or may be absorbed during nucleosynthesis in stars. Laboratory instruments are capable of containing and observing individual electrons as well as electron plasma, whereas dedicated telescopes can detect electron plasma in the outer space. Electrons have many applications, including welding, cathode ray tubes, electron microscopes, radiation therapy, lasers and particle accelerators.

now happy?

Consider, for instance, an electric current within an aqueous solution of sodium chloride. The charge carriers are sodium and chloride ions, not electrons.

2. ok: an article is one of the smallest elementary particles, it has a negative charge and as far as we know, it doesn't exist out of anything 'smaller'

Okay, so you were trying to say that an electron is a fundamental particle. Thanks for the clarification.

3. dude, honestly, i mean that the earth isn't hollow...

Okay, but that's very different from people not believing that the Earth is hollow.

Robosteve takes great pleasure in identifying syntactical errors of logic.

So while it may be true that the earth is not hollow it doesn't prevent anyone believing that the earth is hollow.

See?

1. there is still a difference between charge difference and electricity
are you sure that there is an electric ligne?
2. the guy said 'we don't know what electricity is', i explained that we actually do know what it is and i explained what i was: electrons
3. i never said that there were no people that believe the world is hollow
i only pointed out that the earth isn't hollow

An electric current is a net movement of electric charge. If you apply a voltage across an aqueous solution of sodium chloride, which has finite resistance, then in accordance with Ohm's law you will observe an electric current.

2. the guy said 'we don't know what electricity is', i explained that we actually do know what it is and i explained what i was: electrons

I realise what you were saying now, you just said it badly at the time. I was just clarifying. :)

Again, I realise what you were saying now, but it's not what I thought you were saying at first.

1. hmm, i know that form the charge difference (=volt), but i thought that cause of this voltage difference, the electrons will move in the direction to equalise the volt difference (only if the matery is good.... (opisite from isolation)), anyway, the oposite direction of the direction of your electrons is your powertrail (confusing to explain it in english :()

2.tbh, it didn't sound confusing at all at that point :p, but i can understand that 3. sounds confusing

Well, let's try discussing it using mathematics then. Ohm's law says that:

V = IR

Therefore, if V ≠ 0 and R ≠ ∞, we know that I ≠ 0. So any voltage across a sodium chloride solution will create a current within it, because it doesn't have infinite resistance.

well, that makes it certain that there is a electric ligne, but that doesn't prove that the electric ligne itself doesn't exist out of electrons
this would be so much easier for me if this was dutch :(

We know that the electric current isn't carried by electrons because of the type of chemical bonding in the substance. In metals, there are plenty of electrons which are free to move, which is why they carry the current. In ionic solutions, all of the electrons are bound into orbitals within the ions, so they can't move on their own. However, the ions can move on their own, so the current is carried by positive sodium ions and negative chloride ions, if the solution is one of sodium chloride.

I believe in a round Earth because I have seen the curvature. Some of you FEers really need to climb a hill more often.

Firstly sorry for resurrecting an old(ish) thread. But I'm new to the forum and this seemed like a good thread to make my first post and introduce myself. So I'm a software engineer from England, so I'll be the first to admit I only have a rudimentary understanding of physics and I may well be picked up on errors in future posts.

Anyhow my reasons for believing the Earth is round:

1) When I was eight I had a friend who flew from London to NY on Concorde, when he got back he told me he'd "been into space" I didn't believe him so he showed me a photo he took out of the window of Concorde. I could clearly see the curvature of the earth. (I do realise now that I'm no longer 8 years old, he hadn't been to space, just very high up in the atmosphere).

2) I've used the Vincenty formula to work out the distance from Nottingham to London I then used the odometer in my car to measure the distance and found the results to be similar enough (Vincenty formula works out straight line distance, road distance was slightly further due to there being no road from my front door in a straight line to London), if the earth was flat the odometer would have recorded a greater variance.

3) I've seen ships disappear over the horizon, I've seen Tom's rebuttal is to read the literature on this 'illusion' so I did and saw a major flaw straight away. it correctly stated that smaller distinguishable parts of a whole disappear first when getting further away. Which is why the hull disappears first. But wait, the hulls on all the ships I've ever seen are a damn sight bigger than their superstructures. I've seen the smaller part of a whole disappearing first in other circumstances such as on the range the head of the target disappears before the body, hang on a sec that's the top and my eye level was below it??!!??!!.

4) I've seen plenty of videos and photos of the Earth as observed from space / high alt. If the Earth isn't round these must be fake, therefore my eight year old school friend must have been a forger and/or a liar.

im in 8th grade, and in my understanding, electricity is the movement of electrons

and also i know that in a solution full of ions, (plasma or ionized gas or acid solution) the electrons may move around freely (in a sense to some extent)


and i believe the earth is round because i can see a horizone LINE,  if it was flat, i would see a horizon POINT right? due to objects getting smaller and smaller converging to a POINT.


also i have seen pictures of earth from the moon, and the earth is round

and you can circumnavigate the earth

and the earth casts a CIRCULAR SHADOW on the moon
