How 3D Printers Work

Reading time 5 min
Views 81

3D printing, also known as additive manufacturing, is a transformative technology that has revolutionized the way we create objects. At its core, 3D printing involves creating physical objects from digital models by adding material layer by layer. This innovative process has made it possible to produce items with complex geometries that were previously impossible or too expensive to manufacture with traditional methods.

The evolution of 3D printers can be traced back to the 1980s, when the first processes for additive manufacturing were developed. Initially, these technologies were used primarily for prototyping purposes in industrial settings. However, over the decades, advancements in technology have expanded the capabilities of 3D printers, making them faster, more affordable, and capable of working with a wider range of materials. Today, 3D printing is not just for prototyping; it's used in production, medical applications, fashion, architecture, and more, marking its transition from a niche technology to a mainstream tool.

From Tissue Engineering to the Adult Industry

Level of difficulty Easy

One of the most traditional topics nowadays is the unexpected career shifts from various professions to IT and vice versa. I have this fantastic colleague – a professional butcher by training. He sets up monitoring systems like a pro and can defend his point of view convincingly. His education certainly plays a part in that.

You can also include me among those with a peculiar career switch. As many remember from my previous posts – I originally started as a doctor, who then veered towards fundamental science and tissue engineering. All those diversions with stem cells, growing organs in bioreactors, and other atypical experimental tasks. And then, out of the blue, I was invited for an interview at a large telecom company... Long story short, I found myself as a DevOps in a company dealing with complex projects, some of which are about adult videos. Yes, those very special educational movies for adults that drive progress, with petabytes of traffic, millions of users, and all the other joys.

Here’s how it works for us - there comes a time in a business when they realize, that's it. We've arrived. The infrastructure is working, everything seems fine, but it's built on hacks carefully laid by three generations of employees. There’s no documentation, nobody remembers how it all works. If a server dies, resurrecting it would be a miracle.
And that's usually the moment when we, the WiseOps team, come in. We start dissecting every nut and bolt of the archaeological layers of code, architecture, and business logic. We already have dozens of clients, three of whom are in the video content business.

Let's dive deeper, and I'll try to show you what this whole industry looks like through the eyes of a doctor/bio-engineer/DevOps.

ALGEBRA OF MUSICAL TEXT

ALGEBRA OF MUSICAL TEXT

Sergey Pshenichnikov, Tatiana Sotnikova

Trio Sapiens

Musical text can be represented using matrix units, like the description of verbal texts and other symbolic sequences. In the future, mathematical recognition, and creation of musical sense with substantive justification for intermediate calculations (as opposed to AI) may become possible.

Sound has four properties: pitch, duration, volume, and timbre. Timbre is not considered yet. The dictionary of the algebra of musical texts is built on the basis of musical notation for the piano.

The duration here, for the sake of brevity of the first presentation, is considered as «absolute». «Relative» is not considered, although intervals are very well studied, and their features will be needed to categorize composers.

The complexity of the musical text for the application of mathematics is explained by the desire to simplify the reading of musical notes by musicians and to minimize the use of lower and upper additional lines.

To apply text algebra to musical symbolic sequences there is no need to use a five-line staff. What is useful and familiar to musicians is «unbearably harmful» for the use of algebra. It seems advisable to use a one-line staff. In this case, the musical text becomes like the verbal text.

To solve the problem, you need to find a transformation of the canonical musical text into a «thread». And as always, for a new application of algebra, correct coordination of the subject area is necessary. In this case, each used musical notation and symbol of modern musical notation must be assigned its own serial number (natural number).

Instead of a sign, you can use the names of each note symbol - then it will be a verbal notation of musical texts written in one line «thread»).

Since the musical scale is completely represented by piano keys, the first section in height of the dictionary of musical texts consists of 88 numbered white and black keys (of which 52 are white). This eliminates the need for an octave division of the scale, octave transfer signs, keys, five alteration signs (key and random), diatonic and chromatic semitones.

All notes of the scale became fundamental in algebraic musical notation. There is an order of magnitude more of them of them than the main stages of Guido Aretinsky, but the alteration signs and names of octaves disappeared, the use of which made musical texts algebraically incompatible with verbal texts. Numbers from 1 to 88 in algebraic notation constitute a fragment of the pitch dictionary for the «thread» one-line staff.

Numbering (coordination) of notes is needed to become in the future indices of mathematical objects (matrix units), which will replace the signs of notes or their names. These matrix units are binary generalizations of integers (hyperbinary numbers). The operation of division with remainder is defined for them, as for integers. The operation will allow you to divide musical texts and their f

ALGEBRA OF SENSE

Sign sequences (for example, verbal and musical texts) can be turned into mathematical objects. Words and numbers have become one entity, a representation of a matrix unit, which is a matrix generalization of integers and a hypercomplex number. A matrix unit is a matrix in which one element is equal to unit, and the rest are zeros.

If the words of the text are represented by such matrices, then concatenation (combination while maintaining order) of words and texts becomes an operation of adding matrices.

You can perform transformations with texts using algebraic operations, for example, dividing one text by another with a remainder. Mathematically recognize the sense of text and calculate the context of words. In this case, algebra helps to interpret all the intermediate stages of calculations.

A person sees and hears only what he understands (J.W. Goethe). Understands what he attaches sense to as significant for him. Sense is subjective and depends on the interests, motivations, and feelings of different people.

L. S. Vygotsky distinguished between the concepts of «sense» and «meaning»: «if the «meaning» of a word is an objective reflection of a system of connections and relationships, then « sense» is the introduction of subjective aspects of meaning according to a given moment and situation».

According to G. Frege, «meaning» are properties, relationships of objects, «sense» is only part of these properties. In this case, both “meanings” and «sense» are called one «sign», for example a word. Two people can choose from a list of meanings for one word two non-overlapping fragments (two senses) to interpret it.

В аэропортах продают подушки для сна сидя в полете. Надувные и обычные. Надувные удобнее носить и возить, но они долго не живут. А обычные по размеру как ручная кладь в Победе.

Обычная сверху и надувная снизу
Обычная сверху и надувная снизу

Если вам нравятся надувные, то полезно знать, что в полете давление в самолете на 25 процентов меньше чем на земле.

Поэтому если надуть подушку нормально еще до взлета, то она при наборе высоты будет раздуваться пока швы не разойдутся.

Надо ее или сдувать по мере взлета или надувать уже на высоте.

А не надувным подушкам высота не страшна.

Вдоль торца платы ряд отверстий

Выходящие провода крепятся хомутами прямо к плате через отверстия по краю платы.

Или есть специальные хомуты, которые вставляются в эти отверстия.

Принимаются предложения и идеи по всяким полезным видам крепления проводов.
