Also, I think it's silly to make an animal eat vegan if that's not it's normal diet.

What is the difference between episodic and semantic memory?

Episodic memories are memories from our life events and experiences. They are concerned with when and where an event occurred, and how it relates to us. Semantic memories are the factual and conceptual knowledge we have about the world.

What type of memory goes first in dementia?

Semantic memory is at first impaired in the language of [alzheimer's] patients, affecting verbal fluency and naming. Semantic loss ... may occur several years prior to diagnosis.
__

Age-associated memory impairment is considered to be a normal part of aging. It doesn't mean you have dementia. Though you may have difficulties remembering things on occasion, like where you left your keys, a password for a website or the name of a former classmate, these are not signs you have dementia

I guess I could have guessed what the answer is, but ...

difference between capacitor and battery?

A battery is an electronic device that converts chemical energy into electrical energy to provide a static electrical charge for power, whereas a capacitor is an electronic component that stores electrostatic energy in an electric field. [the definition of a battery seems odd here... "static electric charge"?? ]
__

Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly

Probably the most memorable moment of meeting the business end of a stun gun is created by the capacitor.

I guess I'm being anal, but to say "charged particles" instead of just "electrons" seems odd as well. It would seem to suggest it's a variety of particles. I think this is probably laughable to a physicist. But I could be completely wrong ... it is also laughable to consider me knowledgeable in these matters

Charged particals also include positive ions. To wit, from wikipedia:

Quote:

A capacitor consists of two conductors separated by a non-conductive region.[24] The non-conductive region can either be a vacuum or an electrical insulator material known as a dielectric. Examples of dielectric media are glass, air, paper, plastic, ceramic, and even a semiconductor depletion region chemically identical to the conductors. From Coulomb's law a charge on one conductor will exert a force on the charge carriers within the other conductor, attracting opposite polarity charge and repelling like polarity charges, thus an opposite polarity charge will be induced on the surface of the other conductor. The conductors thus hold equal and opposite charges on their facing surfaces,[25] and the dielectric develops an electric field.

well, there is no claim here that, say, alpha particles [positive charge] accumulate on one of the plates, which I have trouble picturing. I'm not pouncing on what you said, I just don't intuitively get that

that a charge can accumulate on a plate is something that all people know, and prove to themselves sometimes when they touch a doorknob. So electrons can do this, what about some other particle?

I'm interested enough to look at wikipedia, I might post what I find out

here's something below to ponder about protons, a positively charged particle. A hydrogen atom consists of one proton and one electron, and surely it loses it's electron sometimes. So could these protons exist in a static state?

>>>

Why do protons not move in static electricity?

The electrons are bounded with the nucleus with the electrostatic force which is less powerful than the nuclear force. Therefore, when the energy is given to the atom, the electrons lose from their orbit but proton can not be removed from the nucleus. Hence the proton does not move.

me: this does not tell us about the hydrogen atom, which is a proton-only-nucleus, but in a capacitor hydrogen gas would be as a trace presence. There is a hint here, though, that I will follow up in this observation, which is that stripped-of-electron protons seem to exist in nature as pairs, which then is not hydrogen but helium nuclei. These are abundant in outer space and are called alpha particles, traveling at near the speed of light, also called cosmic rays. Radioactive material ejects alpha particles as well, also I believe only existing as these rapidly moving particles.

Electrons may be the only thing that can exist in this static manner. Not sure though

I respectfully suggest a refresher course in chemistry and physics. A helium nuclei is 2 protons and 2 neutrons. There are isotopes of helium with more neutrons, and an isotope with only 1 neutron. The isotope with just 2 protons and no neutrons (a diproton) is extremely unstable and undergoes decay to deuterium, almost immediate;y as fast as it is created. A diproton is not an alpha particle. An alpha particle is 2 protons and 2 neutrons, which is the same as a helium nucleus.

The positive ions in a capacitor aren't hydrogen nuclei. The positive ions are atoms of the metal plate that make up the positive side of the capacitor, stripped of its electrons during the normal operation of the capacitor.

you must have just browsed my response to think I said that

what a fool I was to 'not pounce on you'

yes the helium nucleus also has neutrons, I forgot. Touche.

Your own refresher course? might not help someone "who can't be wrong" although that describes many of our modern scientists and, I fear, is motivating the nature of your response.

Yet you still cannot justify your previous remark that suggested static charged particles like, say, alpha particles, were on the positive plate. It's a stretch to declare the metal atoms as resembling free particles that could discharge like electrons can. It really suggests you didn't get the question. Your first response also suggests missing the point, as it contained irrelevant points.
