Particle Physics
Relatively recent experimental results have confirmed what philosophers throughout history had theorized all along; that all matter is made up of elementary particles. Those curious about this cutting-edge field of physics known as particle physics should post their questions here, including those about fundamental particles, fundamental forces, Grand Unified Theories, and the extraordinary devices that have been or need to be engineered to research them.

What types of particles are protons and neutrons and electrons?
protons,neutrons are very tiny particles that are found in the atoms.
Are electrons small bits of matter?
Yes. They are sub-atomic particles. In other words they make up parts of atoms.
An electron is 1836 times smaller then a proton.
The mass of an electron is 9,10938291(40)×10−31 kg.
Why don't positrons annihilate the electrons in the same atom when they're released?
The positron released from an atomic nucleus in positron emission (or beta plus decay) appears with high kinetic energy. It's moving very quickly, and because it is, it has an extremely low probability of actually interacting with that atom's electrons in mutual annihilation. That positron will undergo some scattering events to dump energy, and only then will the probability of it being able to actually "combine" with an electron increase to the point where it will actually do so.
What is the difference between colourless meson and colour singlet meson?
They're two ways of expressing the same idea. A "color singlet" meson is a meson consisting of a red-antired, green-antigreen, or blue-antiblue quark-antiquark pair. Since X-antiX cancels out, this is essentially the same thing as saying that the meson has no net overall color charge ... that is, it's colorless.
What is the minimum amount of RAM needed on the target machine to run a QNX Neutrino image?
Unscientific testing (using VirtualBox and the installed native Momentics suite disc.) indicates that a minimum of 16 MB is necessary to load the base command line and 24 MB to load Photon. QNX4 was famous for running in 8 MB of RAM from a floppy disk, and its possible that QNX6 could also be configured for less RAM usage than my above testing indicates.
Where are non-bonding electrons found?
The electrons in the valence shell are those most concerned with bonding and how that occurs. The "non-bonding" electrons are the ones in the inner shells, or the non-valence shells of an atom. Non-bonding electrons are also found in the valence shell. They are referred to as lone pairs. For example, in ammonia (NH3), nitrogen has one lone pair. In most circumstances, lone pair electrons do not form bonds (they do in a special type of covalent bond).
Synonym for electron transport chain in photosynthesis?
what is a synonym of the electron transport chain
A baryon is a variety of heavy subatomic particle created by the binding of quarks by gluons.
Has the large hadron collider destroyed the world yet?

Where is the starter motor on proton persona 1.3?
It is located below the intake manifold. It is located below the intake manifold.
What does the MeV in MeV photon mean?
The MeV means million electron volts. It's a measure of the energy the energy in the photon, which is a quantum (or specific quantity) of electromagnetic energy. This 1 megaelectron volt = 1.60217646 × 10-13 joules of energy.
Is it possible to power a 240V oven off 120V?
Are you certain that you mean "amps"? Maybe you mean 110 VOLTS. The voltage in most home circuits are 110 volts except for a few appliances like driers, well pumps, hot water heaters, etc. And even those appliances probably only use 30 amps or so. The whole house may only have the capacity for 100 amp or maybe as much as 250 amp service. And to answer the question, a 220 volt appliance would not work on a 110 volt circuit.
