| * The [[wikipedia:COVID-19_pandemic_in_Spain|pandemic]] hit the city on late March 2021, three months after starting working at Webhelp. Along with other Webhelp employees he was sent home and continued working from there. During the many quarantines, he enjoyed passing his time reading mathematics, listening to Greek music and chilling at the [https://en.wiktionary.org/wiki/terraza terraza] of his flat along with his cat.

| === Patras ===
| |
| * He went to a relatively good high school and focused on hard sciences (Physics, Mathematics, Chemistry), which made sense to him more than the classical studies (Ancient Greek, History, Greek language).
| |
|
| |
| * In the last year's exams, he sat at the pretty infamous, for the stress imposed to the students, Panhellenic exams on Physics, Mathematics, Chemistry and Greek composition.
| |
|
| |
| * He sat this exam twice. His goal had been from an early age (~16 or so) to get in a Physics department because he enjoyed creating small electrical circuits that would solve a very specific problem. At the first time he wrote 08/20 in Physics, 14.5/20 in Mathematics, 16/20 in Chemistry and 08/20 in Greek composition. The second time he wrote 18/20 in Physics, 14.5/20 (grade reserved from 1st time), 16/20 (grade reserved from 1st time) and 10/20 in Greek composition. He entered the Physics school but from the beginning we was drawn towards mathematics, consequently abandoning electronics and circuits.

|
| |
| * People from that period of his life that played major role in his future development were: his father Logothetis (from [[wikipedia:Naxos|Naxos]]), his mother Chrysa (from [[wikipedia:Palaia_Epidavros|Palaia Epidavros]]), his physics teacher Vaso Xouria and his uncle and mathematics teacher Elias Tourloukis.
| |
|
| |
| * Logothetis had been the theoretical mind, the academic scientist of the family and made sure both he and his brother Panagiotis would learn how to take decisions based on reason and not emotions. Logothetis studied economics and management at the prestigious [[wikipedia:ASOEE|ASOEE]], and afterwards he furthered his studies in the '70s at the UK, at the university of [[wikipedia:University_of_Southampton|Southampton]] and that of [[wikipedia:Lancaster_University|Lancaster]], from where he got a MSc in Management sciences. After returning from the UK back to Greece with Chrysa, he was appointed as a professor of [[wikipedia:Management|Management]] at the [[wikipedia:Technological_Educational_Institute_of_Athens|Technological Educational Institute of Athens]] and later at the '90s at [[wikipedia:TEI_of_Patras|TEI of Patras]] where from he retired sometime at the '00s. During all his years he's written several books related to management, a partial list of which can be found [http://okeanos.lib.unipi.gr/Author/Home?author=%CE%9B%CE%B9%CE%B1%CF%81%CE%BC%CE%B1%CE%BA%CF%8C%CF%80%CE%BF%CF%85%CE%BB%CE%BF%CF%82%2C+%CE%9B%CE%BF%CE%B3%CE%BF%CE%B8%CE%AD%CF%84%CE%B7%CF%82 here], at the library of the [[wikipedia:University_of_Piraeus|University of Piraeus]].

|
| |
| * Chrysa had always been the practical mind of the family that brought the stability and harmony needed. A cook extraordinaire. Having finished a technical school in Athens of the 50s that specialized on cosmetics, at an era when women rarely would go off for studies as such behavior was against the social norms and expectations. She worked as a successful professional in the cosmetics industry till she got pregnant to Michail and Panagiotis, when she decided to devote herself to the careful upbringing of her children, quitting her full time job.
| |
|
| |
| * Both of his parents during their lives chased their dreams even if those dreams went against the social norms and dogmas.
| |
|
| |
| * Logothetis and Chrysa now live a quiet life together outside Patras, at a remote village of mountain [[wikipedia:Panachaiko|Panachaiko]] along with their numerous cats.

| * He was very fortunate to have excellent professors that shaped the way he thought and did research.
| |
|
| |
| * A few names: the professor of General Physics (Φ1, Φ2) and Newtonian Mechanics (ΚΜ1), [[wikipedia:Nikolaos Kylafis|Nikolaos Kylafis]] had a great impact on him, and introduced him in the axiomatic way of thinking. Was tought Calculus (M1, M2) by the very stimulating [https://scholar.google.gr/citations?user=X9csaEcAAAAJ&hl=el Taxiarchis Papakostas]. Was introduced to the lovely field of Linear Algebra and to Probability theory (ΜΦ1) by [https://www.physics.uoc.gr/en/faculty/i.papadakis Iossif Papadakis].
| |
|
| |
| * He had been taught [[wikipedia:Dimensional_analysis|dimensional analysis]] by the legendary [https://www.physics.uoc.gr/en/faculty/e.economou Eleftherios Economou]. Ordinary Differential Equations (ΣΔΕ) by [https://de.wikipedia.org/wiki/Elias_Kiritsis Elias Kiritsis]. Self-studied Partial Differential Equations (ΜΔΕ) and Complex Analysis (ΜΦ2). Sat on two graduate Physics classes during his last year of studies (Quantum Many Body Theory and Analytic Mechanics) that were given by [https://www.physics.uoc.gr/en/faculty/g.psaltakis Gregory Psaltakis]. Psaltakis had shown him the beauty and unity of mathematical physics, something that left him an everlasting impression.
| |
|
| |
| * Was taught Experimental Physics with [https://www.physics.uoc.gr/en/faculty/c.haldoupis Christos Chaldoupis] and [https://www.physics.uoc.gr/en/faculty/d.charalambidis Dimitris Charalambidis]. Was introduced to computational physics (using Fortran 77) firstly by Christos Chaldoupis mentioned earlier and then by [https://www.physics.uoc.gr/en/faculty/x.zotos Xenophon Zotos]. The second one made his experiences with Fortran77 pleasant. The first one showed him that he was surely not fond of experimental physics, but that he enjoyed writing reports on the results of the experiments and doing the analysis, and lastly also introduced him (unsuccessfully) to the [https://www.dislin.de/ DISLIN] Fortran graph library. It was something like [https://matplotlib.org/ matplotlib], but for Fortran.

| |
| * Around 2004 he'd discovered at the Mathematics' department library the book [https://www.amazon.es/Foundations-Analysis-Third-Chelsea-Publishing/dp/082182693X "Foundations of Analysis"] by [[wikipedia:Edmund_Landau| Edmund Landau]]. This book changed his focus from Physics to Mathematics permanently.

| === Edinburgh ===
| |
| * On Sept. of 2011 he got accepted at the University of Edinburgh in the school of Mathematics to read Operations Research at a graduate level. Finished with a PgCert on 2012. [https://www.maths.ed.ac.uk/hall/ Julian Hall] had been of much help and inspiration, then and later.

| === Patras ===
| |
| * In his graduate studies at the [https://www.math.upatras.gr/en/ Mathematics] department pretty much was the place where he became the closest he could become to a mathematician. [https://thalis.math.upatras.gr/~kiordan/ Kosmas Iordanidis] introduced him to a facet of Numerics that he'd never seen before, from the book of [https://mirtitles.org/2012/12/26/computational-mathematics-demidovich-maron/ Demidovich]. [https://www.math.upatras.gr/el/people/ex/past/ Panagiotis Alevizos] introduced him to Computational Geometry from [https://link.springer.com/book/10.1007/978-1-4612-1098-6 Preparatas' and Shamos'] pretty difficult to digest book. Thankfully Shamos' [http://euro.ecom.cmu.edu/people/faculty/mshamos/1978ShamosThesis.pdf PhD thesis] was an excellent read, and after creating a group study to pass this class and with the help of his good friend and pretty bright young mathematician, TaiPanagiotis G., he managed to pass the class the 3rd and last time just before he got removed from the program.[https://www.math.upatras.gr/el/people/grapsa Theodoula Grapsa] introduced him to [https://en.wikipedia.org/wiki/Interval_arithmetic Interval Analysis] and [[wikipedia:Mathematical_optimization#Computational_optimization_techniques|Numerical Optimization]]. [https://www.math.upatras.gr/el/people/ragos Omiros Raggos] introduced him to [[wikipedia:Mathematical_logic|Mathematical Logic]] and Prolog, and also gave him the opportunity to learn [[wikipedia:C%2B%2B|C++]] by teaching during the computer labs sessions the undergraduate students of the department to the practical aspects of the language, the GNU/Linux console, the g++ compiler etc. To keep track of the labs and to share useful material with the students, he'd created a [http://student.math.upatras.gr/~milia/ website].

| |
| * His final project was on [[wikipedia:Active_learning_(machine_learning)|Active Machine learning]] with [https://www.math.upatras.gr/el/people/sotos Sotos Kotsiantis] as a supervisor. If interested, see [https://nemertes.library.upatras.gr/jspui/handle/10889/11340 here] the MSc thesis (Greek).
