How do science finction novels inspire scientific thinking?Science finction novels inspire scientific thinking in multiple ways. Firstly, they create vivid and imaginative future scenarios. For instance, in novels about time travel, it makes readers and scientists alike wonder about the theoretical physics behind it. Secondly, they can introduce new technologies in a fictional context. Such as in 'Neuromancer' which has concepts like cyberspace. Scientists might be inspired to work towards creating something similar or at least understanding the implications. Moreover, these novels can also get people interested in science, which is the first step towards scientific thinking.

Photographic literacy postHere are some basic photography basics:
** I. Pre-shooting preparation and operation **
1. ** Hold the camera stably **
- The camera has a certain weight, so you have to hold the camera steadily. When you press the shutter, avoid shaking your hand, or the picture will easily become blurry.
2. ** The use of halos **
- The aperture was related to the size of the hole in the lens. The larger the aperture (small aperture), the smaller the hole. It mainly affected two aspects:
- Light in: The larger the aperture value (small aperture), the less light in, and the darker the subject. Conversely, the smaller the aperture value (large aperture), the more light in, and the brighter the subject. If you feel that the subject is dark, you can lower the aperture value (use a large aperture). If you want to make the subject darker, you can use a small aperture.
- Depth-of-field (the relationship between the virtual and real background of the object): The larger the aperture value (small aperture), the smaller the depth of field, the clearer the person (main body) and the distant mountains (background); the smaller the aperture value (large aperture), the more blurred the background. If you want to highlight the subject, you can use a large aperture. When shooting a large landscape, you can use a small aperture.
3. ** Shutter related knowledge **
- The shutter was the speed at which the object was captured when the shutter was pressed. The effects were as follows:
- The faster the shutter speed, the clearer the photo of the moving object. Normally, when the subject was moving at a normal speed, the shutter could be set to 1/150 seconds to 1/500 seconds to capture a clearer picture.
- Relationship with the brightness of the screen (exposure time): The faster the shutter value (the shorter the exposure time), the less light enters; the slower the shutter value (the longer the exposure time), the more light enters.
4. ** USB (Light Speed)**
- The higher the sensitivity, the brighter the photo, but the noise in the picture would increase. While maintaining accurate exposure, try to lower the sensitivity to obtain high quality. However, depending on the desired effect, it was possible for some of the scenes to have noise.
** 2. Method of composition **
- Commonly used composition methods included three-point composition (nine-square composition), symmetrical composition, frame composition, center composition, guide line composition, diagonal composition, minimalist composition, and so on. Different compositions could bring different effects. The main function was to guide the audience's attention, make the picture clear, and express different emotions.
** 3. Color **
- The camera could adjust the saturation, white balance, white balance offset, and other parameters to make the photo color normal. The color parameters would affect the overall tone direction, and the color cast would affect the overall beauty of the picture. Changing the color according to the environment can bring different visual feelings (cool and warm colors). One had to be careful to avoid excessive saturation adjustment that would cause "color overflow." Otherwise, even if the exposure and composition were good, the work might not be recognized by the audience.
** 4. Exposing Knowledge **
- Exposures could be classified into over exposure, under exposure, and normal exposure. When overexposed, some areas would appear a lot of white, while under exposure would make some areas appear black. The difference between a photo with normal exposure and the image seen by the human eye was small, that is,"the highlight does not overflow, and the dark part does not die black." The highlight and dark parts had clear details and the color brightness was normal.
** 5. Other precautions (for novices in drone aerial photography)**
- For aerial photography novices:
- The entry-level drone was not much different from the flagship drone.
- The mini series had a wind resistance rating of 5 or above. If there was a need to shoot in extremely windy weather, it was recommended to choose the flagship or the Air series.
- If you can't find the drone, you can pay 50% of the cost to get a new one for free.
- It was easy to blow up the plane when flying sideways. When flying at low altitudes, it was necessary to keep the drone in sight or observe the surrounding obstacles to avoid blowing up the plane. The no-fly zone could not take off normally. You could check the APP, and the red zone was the no-fly zone.
** 6. Ways to improve your photography skills **
- Look at other people's works and do a lot of shooting practice. When looking at photos, he would look at them with questions, observe the composition of other photographers, color matching, arrangement of picture elements, etc., and form his own style through a lot of practice. Moreover, after taking the photo, he could use some retouching software to simply add a filter to improve the photo's effect.
