Nice to have a TP simulation, but one needs an app to install.
Here's my Desmos "TP simulator" (only the linear case, admittedly, no
continuous accelerations here)
4 cases (2x2) shown:
1. Lorentz description
("observed" meaning: measured, back-calculated; showing Lorentz
transform effects)
1a: POV hometwin
1b: POV traveltwin
2. "Doppler/Einstein" description
("observed" meaning: actually seeing, looking at, the other twin!
Besides Lorentz, additional Doppler effects)
2a: POV hometwin
2b: POV traveltwin

Why would you bother to learn piano from someone that's sick in the head???? they are playing piano with a marked deck.. Chopin had a smaller piano then everyone else... it's easier to move your fingers if the keys are closer together. but what would you know...you wasted time on ...Relativity, by another austistic person. i think you're attracted to ...sick people. are you sick too???? Jan, Personal Best, gimme a break! rubbish! -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.
