If the Lorentz factor is not equal to 1, then causality implies that possible signal speed has a supremum V. If in K’ the speed of a signal that is perpendicular to the x’-axis converges to V, then its corresponding speed in K has to converge to V too, where K’ is moving relative to K along the x-axis at some speed v > 0. From this it follows that the Lorentz factor is 1 / sqrt(1 – v2 / V2).
After all, what people call knowledge is either the generally accepted belief, or just encyclopedic facts. (A.J. Christian)

At last it came to me that modus ponens was suspect!
Every concept has its inherent contradiction, which is gradually reached as time goes by, and works its way up until it destroys the original concept.
Oversimplification is a means to counteract overfitting.
Those who know little tend to oversimplify. Those who know a lot are prone to overfitting, or rather, radical fallibility.
You can’t x-ray someone and show that they have human rights. (Edward Slingerland)
The opposite of a profound truth may well be another profound truth. (Niels Bohr)
“Strange loops” attract consciousness from their environment, like air flowing into the lungs. As the density of consciousness becomes higher and higher than that in the surroundings, the strange loop will seem more and more as if it was a separate conscious entity, like a developing drop of water. When the strange loop perishes, the consciousness in it dissolves back into its environment.
Under increasing scrutiny, in ever greater depth, time has lost layers one after another, piece by piece. (Carlo Rovelli)
Perhaps poetry is another of science’s deepest roots: the capacity to see beyond the visible. (Carlo Rovelli)
