Here is another AI satire pop music.

NASA’s Apollo missions - from Apollo 12 on - used Plutonium-238 to power the Apollo Lunar Surface Experiments Package (ALSEP), except Apollo 13. The 4 kg Plutonium of Apollo 13 fall into the pacific ocean on Earth, because the LM was returned to Earth. Source...

I think, consciousness is not (yet?) understood by anyone.

The biggest problem of AI is, that the memory chip prizes increase.

No, see above in posting #35.

As written in the screenshot, this works because the transformation is linear. Therefore, you can re-write all primed variable in terms of the unprimed variables in the following way: ##t' = Ax+By+Cz+Dt## and so on. This means you can write both polynomials so, that they depend on the same...

Another problem is, that they spread physical nonsense, for example "Light Doesn't Actually Move | Leonard Susskind Explains".

Welcome to PF!

Yes, the principles of LET are different than those of SR. But the resulting predictions coincide. Principles: SR: There is no preferred inertial frame and no absolute time. Time is, what a clock measures. LET: There is an undetectable preferred frame and and undetectable absolute time. In a...

I think it is "Galilean and Einsteinian".

There were different versions of LET. Early versions (between 1892 and 1895) explained the failure of the negative ether drift experiments (i.e. MM) to first order in v/c. So they did have limited predictive power. The final version (1904, with corrections in 1906), which is today usually...
