What's this crap?? No tensors content inside the above equality I asked
about, cretin.

Ohh, I see... LOL

Has nothing to do with tensors, idiot, you dont even know what you wrote.
Here we go once again
∆τ = √((∆t)² – (∆x_i)²∕c²).
No tensors. Which seems to be consistent. As you, an almost half of an
engineer, are discombobulated when it comes to the domain of tensors.
