Teaching general relativity theory in high school: why, what and how
In this work, which is part of a wider research, the problem of teaching the General Theory of Relativity in sec-ondary school is addressed, even though this theory is scarcely addressed even in physics degree courses.

Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

The Logic of Quantum Mechanics Derived from Classical General Relativity [PDF]
For the first time it is shown that the logic of quantum mechanics can be derived from Classical Physics. An orthomodular lattice of propositions, characteristic of quantum logic, is constructed for manifolds in Einstein's theory of general relativity. A

In this work, we design, implement and analyze a didactic sequence for the teaching of the basic topics of special relativity theory in high school. The sequence proposes a series of situations, specially designed to allow the emergence of the central ...

Death, Time, and the Theory of Relativity [PDF]
Abstract This chapter contains a reprint of “Death, Time, and the Theory of Relativity,” which was published in 2011 in the Journal of Pain and Symptom Management. The author addresses the question of what providing end-of-life care is worth, and how this can be justified using some basic economic and quality-of-life metrics.

How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Einstein’s First Systematic Exposition of General Relativity [PDF]
This paper will serve as the editorial note on Einstein's 1916 review article on general relativity in a planned volume with all of Einstein's papers in Annalen der Physik.

Why Einstein did not believe that General Relativity geometrizes gravity [PDF]
I argue that, contrary to folklore, Einstein never really cared for geometrizing the gravitational or (subsequently) the electromagnetic field; indeed, he thought that the very statement that General Relativity geometrizes gravity "is not saying anything

Electrodynamics in the General Relativity Theory [PDF]
The restricted relativity theory resulted mathematically in the introduction of pseudo-euclidean four-dimensional space and the welding together of the electric and magnetic force vectors into the electromagnetic tensor. Einstein's general relativity theory led to the assumption that the fourdimensional space mentioned above is a curved space and the ...
