Quadratic equations

Ah!
You begin to understand my withdrawal from mathematics!
Give me words and I am all attention.

Mass matters !

Pmb,

I take your meaning and fully appreciate any feeelings you entertain ... rage or impatience. You are following in my own footsteps from long ago ! ! Except I was groping around in the dark and the only colleague who was interested up and died on me .

Frnkly, should you wish to embrace Khgsics, then you must park your Physics hat. The two philosophies run in double harness but, at the moment, a good grasp of Physics is doubtless the cornerstone.

Thank yo for your interest

Ken

I don't understand what you're talking about. Please explain. What is it that you think that I'm impatient about or am raging about? I assure you that it's not true. It's almost always troublesome trying to guess what someone else's feelings are in forums like this. I'd like to ask you kindly if you will refrain from doing it please. If you wish to know then simply ask and I will tell you. Okay? Thanks.

I don't know what "Khgsics" is. Please explain.

PMB,

I am trly sorry if I unintentionally have caused offence. It wwas a clumsy attempt at being flippant !

I fear that, in my dotage, I need all concentraton on the writing when in truth I often needit elsewhere.

But thanks for your courteous correcton.

Hi Ken!

You're very welcome, my friend. I'm very aware that phrasing something even the slightest wrong way, even if the intention is very good, can lead people to think that I was trying to be an "a-" when in fact I was trying to be very kind, which I always try to be.

Please keep the following in mind for future purposes: if I ever appear to be a jerk that you're actually reading it wrong. I am always trying to be kind. Okay?

Best wishes,
Pete

Mass (symbolized m) is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram (kg).

The word dimensionless usually refers to units in (basic) Physics. I think the term you are looking for is "scalar quantity."

Mass is not a dimensionless quantity. It has dimensions of mass. You appear to be confusing the different meanings of the term "dimension" in science.

Mass

Every object is made up of matter (Matter is anything you can touch physically) the more matter an object has, the bigger it is, and the more mass it has. Mass is measured in kilograms, kg, or grams, g. Things that have a big mass are harder to move, or harder to stop than objects with little mass. Mass also changes the properties of space-time. In the presence of an object with mass space and time coordinates work differently than far away from an object with mass. Mass (also known as inertia) is a property of energy. Mass (F = ma).
