Recently, the chinese science fiction congress opened online in 2023, and one of the links was the "case fiction festival for young people in the capital", and i immediately told a friend that her son was a little sci-fi whose 11-year-olds had read millions of words。
In fact, our grown-ups may seem to be dreary, abstract science fictions, in which the reality's hard-to-reach scenario carries the children's infinite imagination of the unknown, displays the magic that does not exist in reality and inspires their curiosity..
Children who like science fiction must be very familiar with situations like the one where princess leah, who begged for help in star wars, did not appear, but was able to send messages through her own stereo projection。
And the main actor in iron man, tony stark, also relied on this technology to turn the entire space into a “shower”。
No child should be curious: "how did you do that
And how did those 3d effects work when we were watching big movies? We know we're in a movie theater, but the people and scenes in those movies are as close as they look, and what kind of a 3d glasses are they
Dial m for murder 2d versus 3d
And how does the naked eye 3d effect look like it's out of the screen
It really looks like a giant panda is crawling up to you from the big screen on the side of the road, and it's as if the big panda, which is in front of you, is still attracting every pedestrian who walks through the streets of chengdu。
The big naked 3d panda on chengdu street
These amazing techniques and works, in fact, pass through the eyes of the audience by using the same magic trick, which is everywhere, though visible, but impossible — it is light。
From the most common mobile phones, films, sunlights, cameras, to sophisticated microscopes and telescopes, human use of light can be seen everywhere。
At the same time, optical knowledge is of great importance in the physics section, which is the point of reference for mid-level and high-level examinations。
So much interesting and important knowledge, of course, will not be missed when you are a teenager, and this is the 101st "application of light" that takes children into the wonder of light, from the closest practical point of view, so that they can easily master the magic of optical knowledge
New/books/pre-sale
Special declaration: " the application of the light in adolescence " is included in the ninth edition of adolescence, and the readers who subscribe to the ninth edition of 2023 may not buy it。
From the life of "in situ"
Turning theory into reality from shallow depth
Human life is indistinguishable, and what we see in life is inextricably linked to light, and this period of "the application of light" is a period of learning from life, teaching children to look at the world and learn about the science around them。
3d display for hologram
The initial reference to images floating freely in the air in science fiction films has been made possible in reality by a technique called laser inducing plasma projection。
The rationale for technology is to focus powerful lasers on specific points that are needed, to stimulate nitrogen and oxygen molecules in the air, to produce microlumines — 3d pixels — using these 3d pixels to produce 3d images for magical drifting effects
A japanese research and development team used laser plasma technology to produce stereo images in 2008 (without the need for screen display)。
The naked 3d on the street is of a sort of “deepening” nature and does not use real holographic technology。
In most cases they are automatic stereos showing that the use of various techniques to " deceive" the left eye and the right eye of the audience, while their effects are striking, may be limited in view angles。

And the real holograms, you can hand over a credit card, a note, a personal id, and point to the children's security labels, which use the very presence of light, and use special materials and manufacturing techniques to make the labels difficult to forge

Imaging principles for cell phones and cameras
Today, photos and videos from mobile phones are integrated into our daily lives, and there is a big optical portal behind smartphone cameras
To allow mobile phones to accommodate a range of lenses, previously vertically distributed lenses are placed horizontally within the cell phone and are mirrored by special optical triscopy mirrors。
Such a design would not significantly increase the thickness of smartphones, would break the limits of the normal camera and achieve greater focus
Oppo's smartphone video "blacktech": double-screening technology
Back to the camera that was used for the shooting, by simulating the image of the human eye, it turned the world into a beautiful or interesting image。
The book details the components of the camera, its structure, advanced techniques and several important parameters, as well as the science of selection of lenses and filters. The children interested in photography must not miss the application of the light
Energy-saving gods - led
When it comes to the use of light, the light that can be seen at the head should be the most typical example, from old candles, torches, to modern-day lights, where we live with no light。
Incandescent lamps are very inefficient, and the presence of leds allows energy efficiency to reach 50 per cent, far above traditional lamps, while saving a large amount of electricity, what is the difference behind them? It is also read in great detail。
Microscopes and cam lenses
In many schools, children are exposed to scientific experiments, which are essential for microscopes。
In short, microscope magnifying objects is the same principle as the magnifying mirrors that are common in our lives, relying on the magnification of objects by the lens。
In addition, different types of microscopes are described, as well as the selection of microscopes by interested people, which are also very practical
Astronomical telescope
Astronomy is an observation-based science, and as an astronomer's "claireyes", how does the astronomical telescope draw human eyes closer to space? This article reveals the answer to the question。
In addition to the principles, the article describes the principles of the astronomical telescope and the choice and use of civil astronomical telescopes, which can be said to be the mandatory goals of small astronomical fans
Laser applications
What do dvd players, supermarket scanners, printers, fibre-optic internet connections and industrial metal cutters have in common? The answer is that they all use lasers and are tools that are often used in life。
Also using laser properties and principles, there are laser beauty and near-sighted surgery, as well as the production of chips, to know how scientists achieve magic effects. Two articles in the book can be answered。
Do the diy ring spectrometer
Practice is also a very good way to learn, and the application of light presents a simple experiment that can be operated at home, with a cd, a mobile phone and a few books to see the magic mimic spectrum, with a video presentation worth trying
Systematic and comprehensive presentation of optical knowledge and applications
Closely integrated with high school physics
Optical science is also the focus of the examination for study and advancement in physics, and the introduction of knowledge principles and applications during this period for teenagers is very comprehensive, giving children a more solid impression of knowledge and a strong complement to physical learning in schools for children。
Magnetic imaging
When a child learns about microscope work, it sees the image of the lens, and the formulas involved, once again deepening the memory of the knowledge point
The intervention of light
Beijing 2020
The point of the advanced examination of physics — the interference of light — is the focus of optical literature, and there is a special article in the book
The dilution of the light
The article is also remarkable, as our familiar doctorate in engineering, mr. Haiyun, began more than a thousand years ago when vikings used natural crystals to identify their location, talking about modern-day fish-fishing occult lenses, and the principles of the 3d film, along with illustrations, to describe the bias as “painting”。
The formation of a bias
The principles of 3d movies
Visible speech combined with graphics and videos intuitively
The author's team is a big fan
In fact, physical knowledge is not as hard as many people think, and we invite professional scholars to express seemingly boring intellectual principles in the most comprehensible way, combined with multimedia presentations, to minimize children's reading of articles。
Added to the excellent graphic illustrations, diagrams, and video presentations, the children are able to jump out of the dead-end memory of the formula theorem, lead them to think and come to conclusions, and build a deeper impression of the point of knowledge。
Double interferometry

Auxiliary video (two-dimensional view of the scanned book against the article)
Meanwhile, in the 101st edition of "the application of light" we have gathered a number of distinguished scholars in the field of physics from the institute of physics, imperial college of technology, beijing university, qinghua university ... Formed a super-luxe group of authors who condensed their most specialized knowledge into articles and enriched their children's academic nutrition

Among them, mr. Kang and mr. Phosphate, who have written many times for their youth, will bring 101 issues of the application of light live on june 13 and june 17, please wait ~
In short, there is light everywhere around us. Without light and, of course, the earth's ecology, light made us. The history of humans studying light is almost the entire history of physics; the history of applied light is almost the history of civilization。
We hope that this book will open the door to children's in-depth and comprehensive understanding of optical science, while complementing in-school learning, with a single, dull academic definition, stimulating their interest in optical exploration and their eyes to discover science in life。
