What is Physics?

Hi Alton,
You wrote:

Nope, it meant just exactly what it said.

Then the answer is yes, I did read it.

Hey GC, I *think* you ascribe to the "material from non material" hypothesis. I am just wondering from what bases you draw this conclusion not because I want to tell you you're wrong or fight with you. If any of your bases are the conclusions of "scientists" from experiments I think you deserve to hear an alternative scientific interpretation of the experiments that are claimed to support the "material from non material" hypothesis.

I'm curious, what is "physics" to each of us here? What is physics about?

My two penneth. It is the study of the physical world, i.e. the world that is accessible to the physical senses.

Sounds pretty good. What, exactly, do you think qualifies as "physical"?

You said "accessible to the physical senses". Do you mean that physical = observable?

Alton he did it in two lines...
I want you to do the same.
then I will.

And would you please stop asking people what this and that definition is.
Are you not capable of understanding?
Your a nice guy, but I want you to do what grey cloud just did.....I know I can, and I understand grey cloud.
If I work in electronics, as I did for ten years, and read a voltage, current, on a oscilliscope, then I am observing the quantum resonance of the circuit. If I am tuning and matching the inductance and capacitance of secret military sonar then I am again working with resonance that is achieved via measurements. That means what ever we can take measurements of is observable. MRI, PET, CAT Scan, Electron Microscope, X-ray defraction, etc, etc, etc.

You really do not get anyone but yourself and bill, and that only bill and your attachment to him, could possibly be correct, either that or you hide behind definitions. I am not being mean, but you act like that.

Remember we are friends so no hard feelings bro.

Hi Alton,
The bog-standard five senses we all have - touch, taste, sight, hearing and smell.

Hi Alton,
The bog-standard five senses we all have - touch, taste, sight, hearing and smell.

Thats where a fault lies,imo.
By design or neglect another sense lies almost dormant, our psychic sense. note to self( must learn to spell)
The bog standerd five senses are perfect for the physical, but not the meta-physical.
hence we are locked down in 3D physical reality.
Everything is one, therefore everything must connect to everything, just not though physically.

Hi Alton,
The bog-standard five senses we all have - touch, taste, sight, hearing and smell.

I've never seen, touched, tasted, heard, or smelled an atom. I haven't 5-sensed light either. I 5-sense things like tables, peanut butter, trees, stars, people, flowers, etc. Is anything I can't 5-sense excluded from physics?

Additionally, what about that which nobody has 5-sensed yet? For instance, anything beyond what physicists call "the observable universe" i.e. anything too far away for us to see it. Are these excluded from physics?

By design or neglect another sense lies almost dormant, our psychic sense. note to self( must learn to spell)

I'm not sure this is first and foremost an issue of sensing. There are many things in physics which nobody has 5-sensed, yet they fall under the discipline of physics. I think physics would be a hopeless discipline if we restricted it to only those things which we can touch, taste, see, hear, and smell.

Torak's teeth and nails Alton, you are hard work. WTF do you mean you have never sensed light? Have you never had a sunburn or sun-tan? Here is an experiment you can try at home.
Sit in a dark room with your eyes closed and have your fiancee stood ready with a flashlight.
After 15 minutes open your eyes and have the good lady switch on the flashlight while pointing it at your face.
Once your eyesight has returned, write back at let me know if you sensed the light.

And to make it pedantically explicit, I include the use of tools and technology which enhances or extends ones natural 5 senses. e. friggin' g. microscopes and telescopes etc, etc.

What I mean by this is that light is not what you see, it's what you see WITH. I see a beam/flash because (I assume) *something* goes from there (the bulb, the beam, etc.) to my eye. But I don't see this "something". I see a streak, a flash, a spark, etc.

Essentially, nobody has seen a photon, an EM wave, or a rope. Neither have they tasted, smelled, touched, or heard them. I see a red area on my skin. I notice I went to the beach shortly before, and the red area was facing the sun when I fell asleep. I presume the sun sent me "something" that produced the burn, I decide to call this something light. But all I SEE is the burn, the sun, the sand, etc. I presume something caused these, and I call it "light". I've never seen this mysterious "light" that I assume is the cause of all these phenomena, burns, tans, flashes, etc.

Okay Alton, experiment B.
Sit in a well lit room with your eyes closed. Have your fiancees largest, strongest relative (brother, cousin, whatever) stand behind you with the biggest, heaviest flashlight he can find.
Have him lay that flashlight upside your head with every last ounce of his strength.
Once you've been discharged from hospital, write back and let me know if you sensed anything.

Methinks that expt was not designed with my interests in mind. Additionally I harbor strong doubts about if I would sense anything, ever...

You may be frustrated with me straight to the 9th circle of Hell, but do you get what I'm sayin'?

Thats one pisspoor definition. You see with your eyes, your brains, your consciouness....


Like GC said, your hard work, but I really don't bother. I know your stuck, so I leave you stuck.
Your first response is how free the ropes have made you....no offense but you remind me of a Jehova Witness

Physics is the knowledge of the universe and the ability to take that knowledge and to make the universe do your bidding.

[altonhare]

Which one of these is a picture of 'a' light?

lamp_light.jpg (1.59 KiB) Viewed 10586 times

light_bulb.jpg (2.17 KiB) Viewed 10585 times

light_stick.jpg (1.38 KiB) Viewed 10587 times

sun.jpg (2.49 KiB) Viewed 10585 times

Are all of them light? I just see different objects of different colors with bright areas and dim areas. I think there must be something emanating that results in these observations. Because of the patterns I see I presume this something is primarily emanating from the bulb, the stick, the sun, etc.

Furthermore, if people could "see light", then why have researchers been debating for centuries one what it looks like, its structure? They could have gotten an artist to paint the sun and been done with it!

Physics is the knowledge of the universe and the ability to take that knowledge and to make the universe do your bidding.

What exactly is "knowledge" to you? When someone convinces other people to do what s/he wants, are they doing physics? When I push "print" and get a document am I doing physics?
