It was 1974 and an Engineer from the Department of Neurophysiology named Alberto Caro had designed a device for the experimental work of the department that could be controlled by our CID-201-B computer, compatible with the PDP-8, which I referred to in the article "CONCATISO. My first program.".Due to production priorities, the Central Institute for Digital Research (ICID) did not give us what would later be named as MEDICID-2 and for that reason, with great inventiveness, the eng...

Any two-dimensional screen can be viewed as a collection of rectangular cells. A point and even the entire screen can be defined as such.Almost all cell phones and computer screens are two-dimensional screens.Therefore, anything that runs on mobile phones or PCs or Macs is viewed on a two-dimensional screen as a collection of rectangular cells.In conclusion, anything that runs on mobile phones or PC or Mac can be conceived as a spreadsheet both practically and theoretically.Spreads...

Back in the year 1973-74 I have already told how Dr. Pedro Valdés took me to know the work of the Department of Neurosciences.I immediately met Dr. Thalía Harmony, one of the most intelligent and determined people I have ever met in my entire life, and knowing that I was about to finish the second year of Pure Mathematics, She knew that I had no biological training.I will never forget that he looked at me with those "inquisitive eyes" that he has and told me: "To work here you must...

At the beginning of the 70s we had a computer with 32 Kilowords and 12 bits in length each word and to program it encoded the machine language by hand and could also use a posfix notation language called LEAL although it was difficult for us anyway to translate algorithms especially if what prevailed was the calculation, so frequent in the Neuroscience applications that we developed supported by statistics, including multivariate ones.In those years and also in the 60's, it was com...

It is known to all that the use of Spreadsheets, such as the current Excel, since the beginning when VisiCalc appeared in 1979, have allowed many users without programming knowledge to be able to develop many and varied applications.In particular, the world of economics has been empowered by Spreadsheets. An accountant can directly carry out all or almost all of his work using them, since from the beginning they were conceived with a varied communication with other data processing...

It was the 70's and I continued working as a programmer for the Neuroscience Department using the laboratory computer, which in other articles I have explained that it only had 32 Kilo Words of 12 bits each, a typewriter that could punch 8-bit paper tapes. channels (bits), and an 8-channel paper tape reader.I have also commented that I programmed coding "by hand", and as soon as it was available in the machine language assembler, and also in the LEAL language, which was "postfix".T...

One afternoon of the many in which the programs we developed took hours and even days to produce results, several colleagues were meeting near our computer and the topic of robots came up.Some of us talked about the distance between the human being and the automation of processes by computers, which by the way is currently maintained, others about the development of Neuroscience itself, others the development of mathematics and computing itself, in short, almost any topic fit into...

Any two-dimensional screen can be viewed as a collection of rectangular cells. A point and even the entire screen can be defined as such. Almost all cell phones and computer screens are two-dimensional screens. And some may be three-dimensional. Therefore anything that runs on mobiles or PCs or MACs is seen on a two-dimensional screen as a collection of rectangular cells, or three-dimensional as rectangular cubes. In conclusion, anything that runs on mobiles or PCs or MACs can b...

CONCATISO. My first Program. Second part. By reading the first part you will already have an idea of the computational equipment that the Department of Neurophysiology had back in the years 1972... 1973 Now I will tell the other part: Professor Erwin Roy John, head of the Department of Neurophysiology at New York Medical College, donated to Thalía and her Department an analog "Transient Averaging" computer called "CAT" that was capable of obtaining, from synchronized stimuli an...

Basic Ideas in the History of Humanity. An idea, a conception, a way of working, of direction, and in general any human activity is considered basic when it has never been formulated by anyone before and is also so simple and powerful that multiple ideas and applications have sprung from it throughout history, but none existed or would exist without having been promoted by that basic idea that is always present in all subsequent development. Often, it's not possible to attribute this basic ide...

I still remember when I was programming with GoTo. Programming without using it was not conceivable. Until the revolution started by Dijkstra with his note "Goto considered harmful" came to "structure" our minds for program development.The progress made with "Structured Programming" is incalculable, which allowed not only to increase the speed of having correct programs, but also to increase the number of people capable of programming.At that time, "Top to Bottom Programming" and "...

It was the 70's and then we only had a 12-bit 32 Kilo Words computer, as I have commented, but the problems that we had to solve, especially statistical ones, needed many more resources.So I took on the task of "circumventing the bureaucracy" of the Computing Centers with their way of working: "submit the program and data on paper" and after days or weeks: "come and collect your results" or "the program did not compile" or "the program failed", which made us fix the problems on pap...

CONCATISO. My first Program. Well, first I must tell you where and why the need arose for a program such as CONCATISO, my first professionally speaking program. It was the years 1972... 1973... and the Department of Neurophysiology of the Center for Scientific Research (CENIC), led by Dr. Thalía Harmony, who in passing I will say was my main mentor in my early working years, A CID-201-B digital computer was awarded, manufactured by the then Central Institute for Digital Researc...

{loadmoduleid 135} In other articles I have commented that in the 70s our Neuroscience department had a CID-201-B minicomputer compatible with the PDP-8 of the DEC company and that the CID-201-B had only a typewriter teletype, a perforated paper tape reader, and a paper tape printer.In order to use this equipment, after developing and fine-tuning each program, it was necessary to "punch" the tapes with the data, or, for example, use the CONCATISO program (see article) to convert t...

Galita's life cycle is over, a cute little dog that my daughter Lissi picked up from the street and who gave us a lot of love and happiness.Galita was very naughty. Being at home made Dolly, another bigger dog, dump the garbage can so that she would then be the one digging for food. And that we gave her a lot of food and other things that she liked. But it seems that her nomadic life led her to try to store as much food as she could find.Galita got along with everyone. She was very sociable. I d...

My current works and ideas.Over the years I have been developing a series of works and research proposals that I would like to present to you as a whole for your consideration. For each one you will find here an introduction to the topic and also links to the complete content already more elaborated. Most of the topics are under development and from time to time I add or modify information. Keep this in mind so that from time to time you can revisit the topics that were of interest...
