Holograms are three-dimensional images created using light and laser beams, making them appear as if they are floating in the air. They are made by splitting a laser beam into two parts and recording the interference pattern on a plate. Holograms are used in various fields such as education, science, art, and advertising, and are becoming increasingly popular in entertainment and technology. Scientists continue to advance holographic technology, with potential future applications including holographic displays for phones and computers, holographic TVs, and even holographic objects that can be touched and felt.

Evaluation Report: Emotional Resonance
This document has a moderate level of emotional resonance. The language used is engaging and easy to understand, making it accessible to a wide range of readers. The use of rhetorical questions in the introduction (e.g., "Have you ever seen a 3D image floating in the air or a video that seems to leap off the screen?") creates a sense of curiosity and encourages the reader to continue reading.
The document effectively uses emotional appeals to convey the excitement and wonder of holographic technology. For example, the description of holograms as "magic" and the use of words like "awesome" and "totally" create a sense of enthusiasm and awe. The inclusion of fun facts and historical context adds to the sense of wonder and curiosity.
However, the document could benefit from more vivid and descriptive language to create a stronger emotional connection with the reader. Some sections, such as the explanation of how holograms work, may be too technical and dry for some readers. Additionally, the document could benefit from more personal anecdotes or stories to make the technology more relatable and emotionally resonant.
Overall, the document has a moderate level of emotional resonance, but with some revisions to language and structure, it could be even more effective in engaging and inspiring readers.

Original Document
Have you ever seen a 3D image floating in the air or a video that seems to leap off the screen? These are called holograms, and they can seem like magic. But are they really magic, or is there science behind them?
What are Holograms?
A hologram is a special kind of picture that uses light and laser beams to create a 3D image. The word 'hologram' comes from the Greek words 'holos' (whole) and 'gramma' (message). Holograms can show us objects or people in 3D from different angles, making them look like they are really there.
How are Holograms Made?
To make a hologram, you need a laser beam and a special plate called a holographic plate. The laser beam is split into two parts: one part shines on the object you want to make a hologram of, and the other part shines on the plate. The light bounced off the object and the light from the laser beam crossing on the plate create an interference pattern. This pattern is then recorded on the plate, and when you shine a laser beam on it, the hologram appears.
How Do Holograms Work?
When you look at a hologram, you see a 3D image because your eyes are seeing the light from different angles. This is because the hologram is recording the way light behaves when it bounces off the object, not just the object itself. The hologram is like a map of how the light moves around the object, and when you look at it, your brain uses this map to create a 3D picture.
Where Do We See Holograms Today?
Holograms are used in many areas, such as education, science, art, and even advertising. You might have seen holographic stickers or trading cards that look 3D when you tilt them. Some museums have holographic exhibits that make it seem like ancient objects are floating in front of you.
Holograms in Movies
Have you seen movies like Star Wars or Avatar? Holograms are used to create futuristic special effects that make characters look like they are really standing in front of you. Some movies even use holograms to make actors appear like they are in two places at once.
Famous Uses of Holograms
In 2011, Tupac Shakur, an American rapper who passed away in 1996, 'performed' at the Coachella music festival through a hologram. It was a huge surprise for the audience and showed how far holographic technology had come.
Fun Facts
- The first hologram was made in 1947 by a Hungarian scientist named Dennis Gabor. He was trying to improve the resolution of electron microscopes and discovered that by using a laser beam, he could create 3D images.
- Totally awesome! Holograms can store a huge amount of information, much more than regular pictures. Scientists are working on using holograms to store data for computers.
Advancements in Holographic Technology
In recent years, there have been many advancements in holographic technology. Companies like Apple and Google are working on creating holographic displays for phones and computers. Soon you might be able to see 3D images on your phone without needing special glasses.
The Future of Holograms
As technology improves, we will see more and more holograms in our daily lives. Imagine having a holographic TV or playing holographic video games. Scientists are even working on creating holographic objects that you can touch and feel.
Holograms are not magic; they are the result of clever science and technology. As we continue to learn more about how they work, who knows what amazing things we will be able to create?
