I believe you missed it because it looks like a "Stanley" screwdriver, and everyone who uses tools knows what a Stanley screwdriver looks like, and so your brain just passed right over it!
That's not a hot air balloon. A hot air balloon is open at the bottom where hot gas and air get blown in from a special type of burner. What you made is a Helium balloon. A helium balloon is filled with Helium gas which is lighter than air, and so it floats up away from the denser air close to Earth.
Questions: 1. What do you mean by "Let's imagine that we are on Earth, in a two-dimensional dimension"? We are already on Earth in a 3-dimentional dimension so why do we need to become 2-dimentional?
You said: "In the Earth's frame of reference, we are stationary relative to the Earth." Well, yes, if we are on Earth, we are stationary relative to the Earth! So why make that declaration? Am I missing something?
You said: "The Earth is moving at a speed of 1000 km/h relative to a stationary observer." What is the stationary observer stationary in reference to? If in outer space, you must define the frame of reference that the observer is in. The observer cannot be stationary relative to nothing!
Anyhow, interesting discussion! I love chatting with others about Einstein's theories and the mind-blowing ways that he saw our physical universe.
Q: I'm assuming that the present adjustment is slow?
A: Well, it depends on how quickly a user wants a desired result. I thought it was a tad slow.
My thinking was, whenever a "tool" has an adjustment on it, it's often desirable to provide fast/slow (or rough/fine) selection modes which allows both quick and precise adjustment capability. One possible way to handle that selection without requiring a separate button is to make the resolution variable based upon how quickly or how slowly the user rotates the scroll wheel. i.e., rotate fast and the numbers change in larger steps. Rotate slowly and the numbers change in smaller steps.
While adjusting the high voltage meter to 100 Kilovolts , a huge spark jumped from my keyboard to my mouse and knocked me off my chair! I think you'd better warn people about that before someone gets seriously injured.
I had a feeling about your possible use of AI to compose your scene description because it seemed a little "too perfect". It makes you seem like a RockStaR! (wink)
In one of your earlier scenes titled "Enlightened" you said the following in the scene description: "This scene was republished by me, because my other account was closed of Internet. I can show you evidence."
So, after I read that, I was curious about the other account that you eluded to. I found another scene titled "Enlightened" that you posted with your previous username RockStaR.
I did a search for "Internal images of a standard electrical outlet" on Google Images and got a lot of photos and diagrams of electrical outlets. I'm located in the U.S., but if you are located in a different country, you would probably need to search on "Internal images of a standard U.S.A electrical outlet". Some diagrams are quite complex and some are very simple. So, take your pick!
