Bartalomeo is absolutely right. Let us consider a long rod, supplied with literal marks and having approximately such form: B C D F G H J K L M N P Q R S T V W X Z Assume that the rod is made from combustible material and, after simultaneous ignition of...

Yes, I do, Bernhard. You are absolutely right! One way light speed is relative. It is equal to c in the reference system K, that is at RELATIVE rest, and is different in different directions in the systems, which are moving RELATIVE to the system K. I shake your hand! Einstein absolutized...

Positive solving Zeno’s “Achilles” paradox? How do You find https://www.physicsforums.com/showthread.php?s=&postid=85446#post85446 [?]

Certainly. This is the only reason, but only in the inertial reference system of external nonrotating observer. But I write about the speed on the Earth, not in the inertial reference system. Do You assume that on the rotating Earth it cannot be spoken about the speed? Then, why do we speak...

By a single clock on the rotating Earth! Not in inertial systems of reference. It is impossible to do it in inertial systems of reference (with two clocks impossible too). Impossible and not necessary. Suffice it to look at an inertial system from another inertial system.

In my message I want only to show that on the Earth the velocity C(east) is not equal to the velocity C(west). If we synchronized a set of clocks on the terrestrial equator, using the velocity C(east) or using the velocityC (west), then we obtained the same result. In this case we would not have...

Yes, certainly! This is a thought experiment only. The rotating Earth can be mentally replaced with the rotating Moon (bad, that the Moon rotates too slowly) or with a big fast rotating hypothetical body (planet) without atmosphere. In my message a fundamental, rather than a technical question...

Let us imagine that a radar located at the terrestrial equator near Quito sends a narrow signal directed eastwards. We shall also imagine, that on all line of equator the set of reflectors is located and that the reflectors thus deflect the radar signal radiated eastwards in Quito, that it...

Privet, drag! :smile: It is a logical problem, which can bee solved only by physical (but not mathematical) methods (mathematics describe the unconditional in real life and well-known fact, which contradicts the logic of the ancient Greek Zeno). As far as moving of real spacecraft s in real...

a) According to the condition of the task the speed of "Achilles" relative to "Tortoise" is equal not to 0,1 m/s, but to 1 m/s. Therefore "Achilles" will take 1000 seconds to dock. b) Certainly, the speed of "Tortoise" relative to "Achilles" is equal to 1 m/s too and Tortoise" will take in...

Examining the paradox of “Achilles and tortoise” one should remember that this is only one of several paradoxes, showing (in the opinion of the Eleatics) the illusoriness of motion. The final conclusion of paradox consists not in the fact that Achilles never will overtake tortoise in the...
