El documento describe cómo la humanidad ha medido el tiempo a lo largo de la historia utilizando diferentes métodos y unidades como calendarios, relojes y husos horarios basados en los movimientos astronómicos de la Tierra, el Sol y la Luna. También explica cómo el tiempo se utiliza para medir procesos en diferentes ámbitos como la industria, la medicina, la sociedad y la física.

1. A Fall Sense Of Connection
According to many researches, social networking sites such as Twitter and Face-book help connect many people, but they also make it hard for users to distinguish their truly meaningful relationships in their real life. Though there are more and more casual relationships built through social media, more and more people are feeling lonely in the real world. When people spend their free time on social networking sites, there is less time for face-to-face conversations with relatives, friends, and neighbors. This means that their real connections weaken.
2. Lower Productivity
A lot of people seem to addict to social networking sites, and unable to work at 100% of their working productivity. For example, people are eager to log in their Face-book or Twitter to see what their friends share each day, even when they are at work. After logging in, they find so many things to view and read there that they cannot get back to work quickly. This reduces their productivity at work.
3. Self-Esteem Affected
Comments on social networking sites can negatively affect users’ self-esteem. When people make a comparison with their friends in their network, they may find out that they do not have as many likes or comments as their friends do; as a result, they will feel less confident.
4. Cyber-Bullying
Cyber-bullying is one of the top negative effects of social media. Comments with offensive words can mentally attack the victims, and leave bad emotional scars. Some victims decided to suicide as the only way to finish the pain caused by cyber-bullying. Cyber-bullying has also made many teenagers depressed. Some of them chose to stop going to school as an escape. Some even dare not go out due to deep emotional hurt caused by words in comments.
5. Distraction
When people spend too much time checking updated statuses on social networking sites, they cannot focus on their daily tasks. Facebook and Twitter are continually updated with new statuses which really attract users. This causes a big distraction from study, work, or family tasks. A student who is addicted to Facebook may not complete his homework. A mother who spends too much time on social networking sites may not fulfill the duty with her children. A staff, who spends too much time on Twitter or Facebook may not complete his tasks at work.
Besides many positive effects, social media has some negative effects. People should use social media wisely to get their advantages, and avoid or minimum their negative effects. Users should use social media as means of communication or work rather than being addicted to them.

4. Estos instrumentos, ya sean fijos o portátiles, nos
permiten Medir el tiempo y conocer la hora por

5. A partir de los principales fenómenos astronómicos
(movimientos de la Tierra y apariciones regulares del
Sol y la Luna), el hombre establece un sistema de
división del tiempo repartido en días, semanas y
meses, que le permite organizar su vida
6. Originalmente, el mes se medía a partir del giro dela
Luna alrededor de la Tierra y sus fases sirven como
base para establecer nuestros meses actuales. Los
calendarios lunisolares siguen aproximadamente el
tiempo que transcurre entre dos lunas nuevas, y los
judíos y musulmanes emplean el año lunar.
7. El reloj de arena es un instrumento mecánico que
sirve para medir un determinado transcurso
de tiempo, desde el momento en que la arena
comienza a caer del receptáculo o bulbo superior
al inferior, hasta que termina de hacerlo, y sólo
requiere de la energía potencial de
la gravedad para su funcionamiento.
8. A lo largo de su historia, el hombre ha
utilizado diferentes fórmulas como:
calendarios
relojes
husos horarios
unidades
de esta manera es posible conocer el
transcurso del tiempo.

realizan como lo es una cirugía de

dependiendo de las complicaciones
que surjan
11. Es una herramienta que la sociedad
utiliza para contabilizar los procesos que
hacen durante el día como trabajar,
alimentarse y hacer ejercicio.
12. En la física se aplica en los procesos de
trayectoria, movimiento rectilíneo
uniforme, movimiento uniforme
acelerado y caída libre etc.….
tiempo que dura la caída del
objeto al piso
