Piggy is considering a kind of rabbit shaped balloon, which has two valves on two sides. If the valves open, the air inside will "peeeeee..." until that rabbit disappears in cosmos...A bit regrettable, a picture can't be attached.
Piggy doesn't know whether this can be a fun...
Piggy is considering to design the rabbit shaped balloon very large, weights 200kg, and dubs it "Dandan".
Piggy saw some guys inserted a picture in their post. I wonder how can they do it? I see no tool bar over the operation window. Is my operation interface not the same as theirs? Any instruction is appreciated. Thanks.
Although this is just a vivid analogy, it’s also an explicit conception for “m0 → 0”.
To display an image in your reply:
If the image is large and you need to resize it:
You can choose other widths besides 400. Best results come from widths of 900 or lower.
You need to replace "link to image" with an actual link to an actual image.
You can also use to "post preview" function to test and see if it works, and thereby correct any errors in the coding before you actually post the message. I've found and corrected many errors in my posts this way.
Thank you for the instructions. But piggy doesn't know how to creat a link for a picture in my machine (not on any website).
You don't create the link. The link already exists if the picture is on the internet.
Here is a link to a recent Bing wallpaper image:
Here is the text to display it resized to fit the page:
Here is the result of that code:
It works with your picture. But your picture seems to be on a website. But how to insert a picture is only in the machine iteslf (not on the internet)?
A2k doesn't do that. You can only display images that are already on the internet.
There are places that will host an image on the internet for you. Once a third-party provider is hosting your image on the internet, you can then display it on a2k.
Thank you for the instructions.
Piggy inserts a picture in the local website for testing:
Well come the rabbit shaped balloon Dandan.
Math vs physics, subtle gap
Piggy encountered such a question “m0 → 0” (m0 is the rest mass) in another site last month.
Piggy's humble opinion is as below:
In math we can consider that “m0” is just a mathematical symbol. We can carry out such mathematical operations as “m0 → ∞ ” or “m0 → 0”.
But in physics, for a certain particle, (if no other miscellaneous factors meddle in), m0 is an invariable.
In order to help research what “m0 → 0” means exactly, hereby we need a model: well come a rabbit – shade balloon Dandan. The rabbit – shade balloon Dandan is very large with two valves on two sides. Then what’s “m0 → 0” for him in physics? Guys can imagine the valves open and the air inside “peeeeee…”…until he disappears in cosmos.
Sounds that “m0 → 0” can represent such meaning in math: a series of particles with the rest masses ranging from “…,1kg,…,0.1kg,…,0.01kg,…,0.001kg,…,0.0001kg,…”.
But in physics:
If you want to describe the property of a proton, you can use the symbol m01, and the equations for it are E1 = γm01c², P1 = γm01v, etc;
If you want to describe the property of a electron, you can use the symbol m02, and the equations for it are E2 = γm02c², P2 = γm02v, etc;
If you want to describe the property of a newly discovered particle which has even smaller rest mass, you can use the symbol m03, and the equations for it are E3 = γm03c², P3 = γm03v, etc;
And so on.
But seems that using “m0 → 0” to represent a series of particles with different rest masses is inappropriate.
A rabbit is a "bunny", who loves in strawberry most...haha
Once the third-party provider hides the pictures, they lost their presence here. Really not convinient.
The rabbit shaped balloon (Dandan) now still exists in his home town:
Perhaps he will disappear in this cosmos very soon. Bounce…
