The History of Engineering Thermodics
The development history of engineering energetics was closely related to the development of thermal science. It could be roughly divided into the following periods: * * I. Early development (late 17th century-early 19th century)** At this stage, many experiments and observations about thermal phenomena were accumulated. The heat engine was invented around the 18th century. However, at that time, people did not have a clear understanding of the nature of heat. They could not accurately distinguish the essence of the two basic concepts of temperature and heat. At that time, the popular "thermal mass theory" believed that the high temperature of an object was due to the large amount of "thermal mass" stored. However, the establishment of the Celsius temperature scale from 1709 - 1714 and the Celsius temperature scale from 1742 - 1745 provided a recognized standard for temperature measurement. Later, the thermal technology was also developed, providing a test method for scientific observation of thermal phenomena, thus making thermal science embark on the path of modern experimental science. * * II. Development period of phenomenological energetics and molecular kinetic theory (early 19th century-late 1970s)** 1. * * Establishment of the first law of energetics ** - In 1842, Mayer proposed the theory of conservation of energy, which determined that heat was a form of energy that could be converted into mechanical energy. He also calculated the thermal work equivalent from the difference between the specific heat capacity at constant pressure and the specific heat capacity at constant volume. The British physicist, Joule, established the concept of electric heat equivalent in 1840. After 1842, he measured the thermal work equivalent in different ways. Joule's experiment results made the scientific community completely abandon the "thermal mass theory" and established the first law of energetics, which was the conservation of energy and the form of energy could be exchanged, as an objective law of nature. 2. * * The development of the second law of energetics ** - In 1824, the Frenchman Carnot proposed the famous Carnot's theorem, which indicated the efficiency limit of a heat engine working between two heat sources with a certain temperature difference. Kelvin, a British engineer, formulated the temperature scale of the thermometer based on Carnot's theorem, and Clausius proposed the concept of the quotient. Based on this work, the second law of relativity was confirmed, and the final scientific conclusion on the impossibility of two types of "perpetual motion machines" was made, officially forming the macro thermal theory of thermal phenomena. - The combination of the thermal work equivalent principle and the particle theory (only motion theory) promoted the establishment of the molecular motion theory. The molecular motion theory was the predecessor of statistical physics, providing a theoretical explanation for the microscopic origin of thermal phenomena. * * III. Period of the birth of the mathematical theory (late 1970s-early 20th century)** The combination of phenomenological energetics and kinetic theory of molecules eventually led to the birth of statistical energetics. Maxwell and Boltzmann's classical work on the velocity distribution law of gas molecules, Boltzmann statistics, and Einstein's work on solid heat capacity based on Boltzmann statistics were the important achievements of this period. At the beginning of the 20th century, Gibbs systematically developed the theory of ensembles based on Boltzmann's concept of ensembles, which allowed the field of mathematical statistics to deal with general thermal systems with any interactions between molecules. The development of engineering energetics was a process of gradual deepening and continuous improvement. From the initial understanding of thermal phenomena to the establishment of the laws of energetics, to the combination of microscopic theory to generate statistical energetics, each step was closely related to the scientific research and production needs of the time.

What are some funny engineering mistakes in history that led to funny engineering stories?
A group of engineers were building a water tower. They miscalculated the height needed for proper water pressure in the surrounding area. As a result, the water barely trickled out of the faucets. People in the area had to use buckets to collect water for a while. It was a funny situation in hindsight as the engineers had to quickly fix their error.

slope engineering
Slope engineering was an engineering field that involved many aspects. There was a book titled "Slope Engineering" published by different publishing houses. The content of the book would focus on problems such as slopes, landslides, dangerous rocks, collapses, mudflows, and bank collapses. In combination with relevant national standards and specifications, it would elaborate on the investigation, testing, analysis, evaluation, treatment, and monitoring of slope engineering. It will introduce in detail various slope engineering analysis and evaluation methods and slope engineering treatment measures. It will also give several main application programs for slope engineering analysis and evaluation. There are some problems in the classification rules of the safety level of slope engineering, such as unclear safety level, difficulty in classification, and intermittent changes. Although it is generally determined according to the relevant tables, the actual safety level is basically determined by the severity of the damage consequences (Level 1 when the damage consequences are very serious, Level 2 when it is serious, and Level 3 when it is not serious). There are contradictions between the current classification rules and the content of the table, and there is no corresponding relationship between the slope type and the severity of the engineering damage consequences, which will cause difficulties in the classification of the severity of the damage consequences and the safety level. There were relevant analysis and suggestions for these problems, such as adjusting the form of the safety level division table. From the perspective of the Slope Engineering Technology Conference, the 16th Slope Engineering Technology Conference was held in Beijing on October 21st. The conference was themed with "Safety and Protection of Engineering Slopes under Extreme Conditions", covering the development status and future of modern slope engineering technology, survey and evaluation technology, prevention and control technology, safety intelligent monitoring and early warning technology, ecological restoration theory and technology, new construction methods, new technologies, new equipment, digital and intelligent technology, etc. This reflected the trend of slope engineering towards green, safe, digital and other high-quality development. In terms of slope protection construction, the first step was to survey and set out, then set up a falsework, and then use a cannon machine to drill holes in the side slope (the position of the holes was required to be high, and the error of the hole distance was not more than 5 cm). After the acceptance was passed, an anchor rod made of several processed steel bars was placed, and then the cement mortar was poured into it. After the mortar solidified, the steel bar frame was built, and finally, the slope was afforested (using a grass spraying machine to scatter grass seeds). Through these layers of construction reinforcement, the firmness of the slope was guaranteed. Not enough TV dramas? Hurry up and click on the books below to read the wonderful original novel!
