  • Radiation pressure does not have anything to do with mass-energy equivalence. 1), the energy for this process does not come from the conversion of electric energy into mass, and 2) having a momentum is not a property tied to massive particles. All electromagnetic waves carry momentum according to Maxwell’s theory of electromagnetism, and its transfer is fully explained by his equations and results from the interaction of the EM wave with matter, i.e., absorption and reflection. Each such interaction will transfer momentum to the massive object. This is classical physics, you don’t need any Einstein relativity to explain electromagnetic phenomena because his theories only become relevant for very massive bodies and their movement, and nuclear reactions.





  • That’s also confusing and it is not the full saying. The full saying is “free as in free speech, not free beer”.

    From the FSF website:

    Free software is a matter of liberty, not price. Think of “free” as in “free speech”, not as in “free beer”. Free software is a matter of the users’ freedom to run, copy, distribute, study, change and improve the software.


  • I am very opposed to this. It means surrendering all trust in pictures to Big Tech. If at some time only photos signed by Sony, Samsung, etc. are considered genuine, then photos taken with other equipment, e.g., independently manufactured cameras or image sensors, will be dismissed out of hand. If, however, you were to accept photos signed by the operating system on those devices regardless of who is the vendor, that would invalidate the entire purpose because everyone could just self-sign their pictures. This means that the only way to effectively enforce your approach is to surrender user freedom, and that runs contrary to the Free Software Movement and the many people around the world aligned with it. It would be a very dystopian world.
