CChiara replied to the thread A Is it correct to state that all measurements count photons?.You need your ear to compare the tuning fork and the piano - or some other sense. That uses electromagnetism. Reading signs in Braille...

CChiara replied to the thread A Is it correct to state that all measurements count photons?.Measuring weight uses a scale. Even reading a hand on a watch uses photons to determine if the hand went over a line.on the scale. I...

CChiara replied to the thread A Is it correct to state that all measurements count photons?.Indeed. But is there a really precise measurement device that does not count photons?

CChiara posted the thread A Is it correct to state that all measurements count photons? in Quantum Physics.A text I read some weeks ago claimed that all measurements count photons. Indeed, even a thermometer requires light to be read off, and...

CChiara replied to the thread I On the Quantum Mechanics of Entropic Forces."Black" means: "It does not shine". This is the prediction of general relativity. A non-zero BH temperature means: it does shine, it...

CChiara replied to the thread I On the Quantum Mechanics of Entropic Forces.Jacobson gave a purely mathematical proof: the entropy of black holes, their temperature, and their mass/energy, taken together, imply...

CChiara reacted to BaronBautista's post in the thread A Thermodynamic Approaches to Quantum Gravity: Discussion with
Like.
Jacobson’s work (1995) [1] demonstrated that Einstein’s equations can be derived from thermodynamic principles, suggesting gravity might... -
CI am new here. Above all, I am passionately curious about fundamental physics.
