The founding concepts of physical measure:

In all of physics, there are only three concepts of measure that cannot be
further reduced to ratios of other measures:

They are: 1) Length, which is the distance between two or more points, lines
or objects in space; 2) Force which is the thrust exerted between two or more
particles of material substance, as they displace each other from
simultaneously occupying and/or passing through the exact same place, and
Time, which is a measure of the time period during which force and other
physical phenomena last.

All other physical measures are ratios and or proportions of these three!

In particular, an object’s mass and/or inertia is a combination of all three:
It is the ratio of the force exerted on and/or by it, to [divided by] the
acceleration caused; where the acceleration is the ratio of the displacement
[the length of the distance between where the object would have been, gone or
stayed if not displaced] divided by the time period during which it occurs.

One slug, the _customary_ unit of mass; is defined as one pound divided by the
acceleration it causes: 1 slug :: 1# sec^2/foot.

Attempts to define force as the product of a unit of mass and its
acceleration are all doomed to failure: For 1# does not equal the product of
1slug and its acceleration: Because the _product_ of one slug and 1
foot/second squared _leaves_ units of 1# per second squared per foot.

One newton does not equal the product of 1 kg and its acceleration: Because
the _product_ of one kg and 1 meter/second squared _leaves_ units of 1 kg
per second squared per meter. A second is a unit of time measure and a meter
is a unit of length!

Length, and time are standardized measures, as is mass. Force is a derived
unit.

****ing imbecile. There are seven primary quantities:

length meter
mass kilogram
time second
electric current ampere
thermodynamic temperature kelvin
amount of substance mole
luminous intensity candela

Don't get too excited about length. A relativistic universe has four
distinct distances: luminosity (inverse square), angular diameter,
parallax, and proper motion. No two of them need agree to maintain
consistency.
Don't get too excited about mass. It doesn't appear in the Standard
Model and must be inserted artificially (Higgs mechanism), then set
with 20 empirical parameters.

Don't get too excited about time. Clocks can only be synchronized by
being local.

I don't know.
my dictionary shows the 3 primitives to be
1) length l metre
2)mass m kilogram
3)time t second

*excluding electrical quantities which require something else


holog

ps note as speed changes so do the 3 primitives

Shead, you were an idiot before, you are an idiot now.

In a three base unit mixed cgs system, the unit of charge is 1 erg^0.5
cm^0.5, or in terms of the base units, 1 g^0.5 cm^1.5 s^-1. I leave
it to you and Kolker and Shead to figure it out for the Dense Donny
system (granted, of course, that there isn't a snowball's chance in
hell that Shead could ever figure it out, or even understand it if you
were to explain it to him).

It's hard to believe he thought he could hide that much stupid, and
remain incognito with his new name (not signing the posts like u10889
always did).

I wonder what he will do next.

1) Ignore us or deny any connection with Shead.

2) Say that he was not trying to remain incognito and just
changed his ISP and forgot to sign his post.

3) Something even madder that I have not thought of.
