What about absolute simultaneity of the sky (since million years for example)?

Since experimental evidence, it is well known that a desynchronization of clocks appears between different altitudes on earth (simultaneity is relative). However, simultaneity (absolute for the...

Does a new view of aberration of light solve galilean relativity?

Dear folllowers, Imagine you are in 1905, where experiments known today were not done. Does aberration of light exist for a source horizontal to a moving frame? Such a phenomenon (which...

Does a rotating disk (inside the frame) turn slower than an unrolling coil followed by a moving observer?

Imagine a frame A (ground) unrolling a coil at speed ~c. Imagine a second frame B (moving rectiline) following the coil and turning next to it a disk at same speed. If both are supposed to turn at...

What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...
