Топ нейросетей для анализа данных: BotHub, Julius AI, Microsoft Power BI

Помните те времена, когда мы сидели в три часа ночи, пытаясь свести VLOOKUP-ами три кривых CSV-файла, выгруженных из разных CRM, а питоновский скрипт падал из-за одной запятой не в той кодировке? Кажется, это было в прошлой жизни... На дворе апрель 2026 года. Нейросетевой анализ данных – это уже не игрушка для гиков и не R&D-эксперимент с непредсказуемым бюджетом. Это суровая, ежедневная необходимость. Если вы сегодня не используете ИИ для очистки, обогащения и анализа датасетов, вы всё равно что копаете котлован чайной ложкой, пока соседи работают экскаватором. По данным исследований Стокгольмского института окружающей среды, современные LLM достигают 85–90% точности по сравнению с ручной разметкой и анализом даже в таких субъективных вещах, как оценка политических и климатических документов. А в жесткой математике и структурированных таблицах этот процент стремится к абсолютным 100%. В этой статье я собрал ультимативный топ-9 платформ , сервисов и подходов, которые перевернут ваш воркфлоу. От уютных табличек в Google Sheets до суровых кластеров для машинного обучения. Мы разберем, какие инструменты реально работают на проде, и поймем, как стать настоящим архитектором смыслов. Пристегните скафандры, мы погружаемся. И начинаем с абсолютного геймчейнджера.

Bayreuth Polymer Scientist Receives the Heinz Maier-Leibnitz Prize

Chemist Prof. Dr Alex J. Plajer from the University of Bayreuth has been awarded the 2026 Heinz Maier-Leibnitz Prize of the German Research Foundation (DFG). The prize is considered the most important distinction for early-career researchers in Germany.

Another photo from my training, this time captured during the analysis of a polymer sample under the light microscope ✨🔬

The material is based on a polycondensation reaction of 4,4´-dihydroxybiphenyl with an aliphatic dicarboxylic acid chloride. Using an aqueous phase with sodium hydroxide and a phase transfer catalyst results in a polymer whose structure and properties strongly depend on the ordering of its molecular chains.

It becomes especially interesting when looking at the thermal and optical properties. In differential scanning calorimetry (DSC), the material shows two endothermic transitions. This means that the ordered structure is not lost all at once, but stepwise via a liquid crystalline phase into a fully isotropic state.

Under the polarizing microscope, this order becomes directly visible. The sample exhibits birefringence, meaning direction-dependent refraction of light. This only occurs when regions within the material are organized on a scale comparable to the wavelength of light. These structures are exactly what create the fascinating patterns and colors in the image.

In short, a small window into the world of liquid crystals, somewhere between ordered structure and thermally driven disorder.

I love these moments when chemistry is not only measurable, but also visible.

I just found this photo of one of the most disgusting preparations of my entire training… PU foam!

First, a highly branched polyester was synthesized from adipic acid, oleic acid, and phthalic anhydride with 1,1,1-tris(hydroxymethyl)propane using PTSA as an acid catalyst. The polycondensation ran for many hours at ~190 °C under nitrogen and vacuum while water was continuously removed as a by-product.

During the reaction, the acid number (determined by titration, mg KOH/g) was monitored until it dropped below 10, with a target around 5. The resulting viscous polyester polyol was then reacted with tolylene-2,4-diisocyanate to produce rigid polyurethane foam.

Chemically interesting.
Visually and olfactorily… slightly traumatic. 🧪😵

@kimlockhartga 🧵 a #polymer: https://en.wikipedia.org/wiki/Polymer Polymers are large compounds of macromolecules, therefore great to "build" something. We have natural and artificial polymers: Your DNA or coton fibres are made from polymer as well as a plastic bottle.

We mostly built stuff with artificial polymers because they were cheap and very easy to engineer since the 1950s. With the problem of plastic waste, engineering seeks more and more for natural polymers.
