> That is, given the string "1.0e10", it should return a 64-bit floating-point value equal to 10. Err, surely it should be equal to 10,000,000,000. Or more probably, they meant to write "1.0e1".

I'm trained in physical chemistry, rather than physics, so I don't have the firmest grasp of quantum field theory, but I think the analogous "phonon field" would be the Born-Oppenheimer potential energy surface (PES). Vi

I think not. The heat flux decays exponentially with increasing distance between the objects. This is an extremely short range phenomenon, like electron tunneling.

Where does sign on v(i,j) come from? The arxiv paper says that it is possible to extract the phase factor, but it does not say how.

Something like MINRES or GMRES or CGSTAB. Correct me if I'm wrong, but the covariance matrix in GPR should be diagonally dominant, so the diagonal of the matrix can be used as a somewhat effective preconditioner.

I believe the use of the term "magic angle" in this article is at least partially a reference to the technique whose actual technical name is "magic angle spinning" NMR spectroscopy[0]. If course, the angle used in MAS i

Since this is a journal focused on cancer and not machine learning, I can understand why the editors would see this paper as being worthy for for publication. Unfortunately, many of the readers will read the paper uncritically. If possible,

I think that's an unfair characterization of numpy's functionality. Numpy introduces data structures not present in the core python library (another one of your complaints about python, though it's not clear to me why it matt

Only insofar as numpy relies on BLAS and LAPACK for certain functionality, and most (all?) implementations are written in Fortran. The actual numpy source code contains no Fortran; you don't need a Fortran compiler to build numpy. Scip

Blood should not ever be present in ground beef, cooked or not.

They are taking artistic liberty with the term "bleed". Obviously, the fake meat doesn't have a blood analog, but it does have a myoglobin analog, which is what causes the juices secreted by real meat to be red.

The greater issue with thalidomide is that it racemizes in the body. That means even if you take the enantiomerically pure form of thalidomide which treats morning sickness, the teratogenic form will be generated in the body.

My point is that if you can identify how the private key is stored in the video, then it should be possible to develop a strategy to destroy that data without damaging the integrity of the file. Presumably the key will be hidden in such a w

If it is possible to strip the private key, e.g. by re-encoding, then an intelligent and determined leaker would simply do that before distribution. They likely won't be tempted to take the reward for themselves, given the consequences
