Just a coincidence
On February 26th, 1616, the Catholic Church prohibited Galileo Galilei from spreading his ideas about heliocentric since his theory contradicted the stablished idea based on the geocentrism.
400 years after, in February of 2016 my first version of MEDT was rejected from the RSC Advanced journal. I chose this journal since I had recently published several of my relevant achieves in this journal, such as the Parr Functions. Moreover, in 2014, I was appointed Fellow of the Royal Society of Chemistry by the invitation of some members of the RSC editorial. Nevertheless, some referees decide reject my MEDT since it contradict their molecular orbital theories about chemical organic reactivity.
MEDT was also rejected in Tetrahedron journal, newly by referees, that similar to the RSC advances, only reported personal comments, without any scientific argument against recent published studies of organic reactivity based on analyses of the electron density. Finally, in September 2016 MEDT was published in Molecules.
Today, more than 180 manuscripts have been published within MEDT, and with my large experience in the study of chemical organic reactivity, with more than 340 published manuscripts and more than 13.000 citations, MEDT rejects obsolete reactivity models based on molecular orbitals as the Fukui’s FMO, the Woodard –Hoffman’s symmetry rules, the Morokuma’s energy decomposition analysis, and the Bickelhaupt’s activation strain model.
These people think that their physico-mathematical models are a different view of chemistry than the one given by MEDT, but unlike the electron density, molecular orbital are mathematical artefacts used only to solve the Schrödinger equation, without any physical reality.
Can a mathematical artefact control chemical reactivity? From my point of view, this is simply an absurdity supported only by physicists without any chemical insight. As I say "Chemistry is not Physics".
Such as Copernican Model provoked a revolution in the concept of the Universe, the Chemistry need in the XXI century a revolution in which many of the concepts proposed along the pass century will be quantum chemically redefined based on the only physical observables, the nuclei and the electron density.
Dear colleagues, today I have created in Twitter MEDT-2016 (@2016Medt) to spread the Molecular Electron Density Theory (MEDT) as a modern model of reactivity in Organic Chemistry.
You can follow the advances of MEDT in this Twitter.
A recent MEDT study about the reactivity of strained benzyne has revealed the chameleonic structure/reactivity of benzyne, allowing its participation in both non-polar, as a pseudodiradical species, and in polar reaction, as an electrophilic carbenoid, with unappreciable activation energies (Tetrahedron 2020, 76, 131458).

This manuscript was firstly rejected of RSC Advances by Gabriel Merino, a physic editor, that showed a complete lack of knowledge of Organic Chemistry to not respond to any of the three rebuttal letters that I sent to the editorial answering the referee’s comments, and in which I emphasised the chemical relevance of this MEDT study.
It is not new, unfortunately many of the very cited manuscripts were firstly rejected by physic editors with a complete lack of knowledge of Chemistry.

A New C-C Bond Formation Model Based on the Quantum Chemical Topology of Electron Density.
ELF topological analyses of bonding changes in non-polar, polar and ionic organic reactions involving the participation of C=C(X) double bonds make it possible to establish a unified model for C-C bond formation. This model is characterised by a C-to-C coupling of two pseudoradical centers generated at the most significant atoms of the reacting molecules. The global electron density transfer (GEDT) process that takes place along polar and ionic reactions favours the creation of these pseudoradical centers at the most nucleophilic/electrophilic centers of the reacting molecules, decreasing activation energies. The proposed reactivity model based on the topological analysis of the changes in electron density along a reaction makes it possible to reject the frontier molecular orbital reactivity model based on the analysis of molecular orbitals.
