The director Denis Villeneuve and cinematographer Greig Fraser in their Dune: Part Two movie made a curious decision to film the scenes on the surface of the Giedi Prime planet in the infrared spectrum. It turned out to have interesting aesthetics and there are some interesting related physics to discuss and speculate about how realistic the look of it is.
Wilhelm Röntgen discovered X-ray November 8th 1895, when he did experiments with cathode rays in a vacuum tube. To capture and save images of the shadows from the X-rays, he used ordinary photoplates. Fortunately, sensitive to visible light silver based photoemulsions turned out to be sensitive to the X-ray too. These photoplates became the first X-ray detectors.
More than 100 years of scientific progress led to the creation of a number of various detectors for recording X-ray images. Developments of the microelectronics and semiconductor manufacturing technologies are crucial for development of the modern X-ray detectors. These detectors can transform the energy of the X-ray photon directly to the electrical signal. They allow capturing detailed, digital, high-resolution X-ray images.
Digital images are easy to work with. For example one can merge multiple macro images into an image of the whole object and represent monochrome images in false colors like Simon Procz did with this X-ray image of a flower he did in 2012.
Weather forecasting has come a long way from the days of observing the sky and relying on folklore to predict upcoming conditions. Advancements in technology have revolutionized how we perceive, understand, and forecast weather patterns. From the early barometers to modern satellites and supercomputers, each innovation has significantly enhanced our ability to predict weather accurately. Let's take a journey through the evolution of weather forecasting technology and explore how it has transformed over the years.
In the vast expanse of the sky, clouds weave an intricate tapestry that holds invaluable insights into the workings of our atmosphere. Far from being mere adornments adrift on the winds, clouds are dynamic entities that serve as indispensable harbingers of weather patterns. Their varied forms and movements offer a window into the ever-changing conditions of our atmosphere, allowing meteorologists to unravel the mysteries of weather forecasting with increasing precision.
Clouds, in their multitude of shapes and sizes, provide vital clues about atmospheric conditions, from temperature and humidity to air pressure and wind patterns. By understanding the different types of clouds and their characteristics, meteorologists can decipher the language of the skies, predicting everything from clear skies to impending storms.
Have you ever wondered how difficult it is to turn something you have in mind into a real product? For example, would you be surprised to see someone controlling a huge iron robot spider that can turn on the spot and walk obediently to his pilot's directions?
To realize his idea, this persistent designer overcame many obstacles: he invented the mechanism himself, mastered the skills of aluminum welding, laser cutting, 3D printing, created a reduced prototype and built one. His project stands out even among the most interesting self-made devices you've read about.
Please sit back and relax while reading this rather lengthy article. During the scrolling through, you will learn about some remarkable inventor and his resourcefulness, irrepressible life energy and practical advice to help you realize your dreams, and someone, perhaps, will be pushed to tell about his own project.
What is ageing? We can define ageing as a process of accumulation of the damage which is just a side-effect of normal metabolism. While researchers still poorly understand how metabolic processes cause damage accumulation, and how accumulated damage causes pathology, the damage itself – the structural difference between old tissue and young tissue – is categorized and understood pretty well. By repairing damage and restoring the previous undamaged – young – state of an organism, we can really rejuvenate it! It sounds very promising, and so it is. And for some types of damage (for example, for senescent cells) it is already proved to work!
Today in our virtual studio, somewhere between cold, rainy Saint-Petersburg and warm, sunny Huston, we meet Stephanie Planque! For those of you who are not familiar with her, here is a brief introduction.
Stephanie Planque was awarded the PhD in 2009 by the University of Texas-Houston Medical School for her advances in applying electrophilic analogs of proteins to decipher the beneficial and harmful functional effects of catabodies. She then expanded her focus to vaccination and therapeutic catabody identification using proprietary electrophilic target analogs. Her work was published in 49 peer-reviewed scientific articles, she has numerous national/international conference presentations. She moved fulltime as a co-founder to Covalent Bioscience in 2018 to focus on rapidly translating their electrophilic vaccine/catabody technologies to clinical reality.
Switzerland: the very name conjures up images of pristine alpine landscapes, picturesque villages, and a sense of tranquility that seems to permeate the very air you breathe. It's a country that's often synonymous with beauty, precision, and adventure. Whether you're a nature enthusiast, a history buff, or simply seeking to indulge in some of the finest chocolates and cheeses the world has to offer, Switzerland has something for everyone. So, if you're planning a trip to this enchanting land, here's a curated list of must-visit destinations and experiences that will make your journey truly unforgettable.
We wrote this article in an attempt to figure out what technical level gas turbine installations are currently at, as well as to understand what the prospects for their development are. At the same time, in our manuscript, we tried to consider an alternative energy conversion scheme that will increase energy efficiency, which will allow for more efficient use of natural resources. We are not completely sure that the alternative scheme presented by us will be workable, since many factors that may affect its operation have not yet been investigated. But as the Chinese philosopher said, "you can't travel a thousand li without taking the first step." We ask the Habr community to read our article, we hope for a constructive conversation.
