This is because sound is produced by the vibration of objects. When a thermos bottle is almost full, the water molecules will start to vibrate, producing obvious changes in vibration frequency and amplitude. These changes can be keenly picked up by our ears to let us know that the water is almost full. When the water is almost full, the structure and arrangement of the water molecules will change, causing the frequency and amplitude of the sound to change. This change in frequency and amplitude was very obvious and could be accurately captured by the ear. Therefore, when we can tell that the water is almost full just by listening, we don't need to look at objects or other external signals, just listen to the sound.

Is this destiny?

Sarah Hill is an introvert who does not want to attract attention. Other than mad coding skills, Sarah knows how to throw a punch. She believes that her biggest problem is the existence of the hacker Omega and her world flips upside-down when the most popular guy on campus approaches her. What does he want? Why her? (Ah, Sarah, that is only the beginning.) JoAnna Hill easily makes friends with her bubbly personality. Some call her a mad scientist, but she prefers ‘Dr. Hill’, because that is what she is. JoAnna is an excellent markswoman who can snipe out any target and she is wondering if her prince charming will ever come. Sophia Hill is the voice of reason, their pillar of support. She is a confident CEO who knows how to get what she wants. Sophia’s degree in law combined with amazing capabilities to analyze the situation and plan ahead make her the perfect strategist (to achieve a goal without ending up in jail). This is a story of three Hill sisters who are navigating through challenges while they uncover the complicated story behind their maternal side of the family. And their father is not a simple man either. Every sister is different, and so are their relationships. They all have in common: trust and belief that if they work together, anything is possible. Mature content! 18+ ***SPOILER? - START *** The story starts with a focus on the youngest sister (Sarah). After about 100 chapters, the oldest sister (Sophia) gets in the romantic spotlight. JoAnna finds herself pulled into romance last, at about 200 chapter mark. ***SPOILER? - END *** Excerpt from the novel... "Do you believe in destiny?", Sarah broke the silence. "Destiny?" Aiden didn't expect such a question. "Yes. The thing that is meant to happen, and there is nothing you can do to prevent it. And when it does happen, everything feels right." "Why would you ask me such a thing?" "Until a few weeks ago I would say that there is no such thing as destiny. That we are all masters of our lives and that everything depends on our actions, or lack of it. But I can't help but wonder: why did I not push you away? ... Why does it feel like everything will be OK as long as we are together? ... You are a piece of me that I never knew was missing. Is this destiny?" "Mmm... if that is destiny, then I approve it.", Aiden lightly kissed Sarah's shoulder and rested his chin on it. --- 1st WARNING!!! Contains descriptions of intimate scenes.

Why should we never judge when we don't know the full story?

Because our limited knowledge might lead us to wrong conclusions. If we judge without knowing everything, we could unfairly mislabel someone or something. For example, a person might seem rude at first, but when you learn their full story, you find out they're having a really tough day and are usually very kind.

How can we avoid judging when we don't know the full story?

Just keep an open mind. Don't jump to conclusions right away. For instance, if you see someone being late, instead of thinking they're irresponsible, just wait and see if there's a valid reason.

Please analyze the short story 'We ate the children last'.

This title is very disturbing at first glance. It might be a very dark and surreal short story. Maybe it uses such a shocking statement symbolically to represent some extreme situation, like the loss of humanity or a very cruel social phenomenon. However, without reading the actual story, it's hard to be more specific.

Why are we always hearing the same old stories?

Well, it could be that the storytellers lack creativity or are too lazy to come up with new ones. Also, some of these same old stories might have a strong cultural or traditional value that people keep passing on. For example, fables that teach moral lessons have been told over and over again for generations. And in the media, some formulas for stories are proven to be popular, so they keep getting recycled.
