Girls, tell me a male scientist or researcher that you know? You would immediately mention Albert Einstein, Nikola Tesla, and many more if asked like that. Now, name a female scientist or researcher that you know? Your answer would have to be Marie Curie. Then it would be difficult for you to name another female scientist or researcher. From there, you will realize that the number of female researchers/scientists is, in fact, less than men. Even though their numbers are few, women scientists and researchers have made a significant contribution, become inspirations for other women, and have even managed to change the world! Then who are they?

Girls, how was your holiday? Long periods of vacation and absence from school will undoubtedly make us less motivated to study. Holidays are indeed a lot of fun, but they often make you lazy to get out of bed. Why don't you watch a movie about school right now to regain your enthusiasm?

From the title above, you, girls, will think that everyone must do this and understand it. Eits... don't get me wrong, girls. Even though everyone understands that other people's opinions need to be respected and understood, it isn't easy to do, and many people don't even realize it when they don't. The most obvious example that you can see is interaction on social media. Many people express their opinion on something, but if you look or scroll through the comments, you will find some things that hate comments, which leads to hate and cancels the person because of their opinion. This also happens because almost everyone thinks that their opinion or belief is the most correct, and the opinion of others is wrong. Not to mention their desire for others to agree with their opinion. This, of course, caused chaos, not even a little -let's be honest, have you ever been like this or not, girls?- evolved because of different opinions.

"Hooray... finally this year me, Mama, and Papa can have a vacation to Switzerland! I'm delighted, and I want to video call Grandma in Indonesia. Eh, but how come mom forbids it, she said Grandma must be asleep. Then I asked, "It's still afternoon here, mom; how come grandma is already asleep?" Mom also replied that in Indonesia, it is already night. I asked again, "how come, ma?" "That's because the time in Switzerland and Indonesia is different, dear." From there, I was confused. How can it be noon in Switzerland right now, and in Indonesia is night?" All because of the earth's rotationSo, if you girls have the same confusion, the answer to this is the time difference! So, what causes the time difference in the world? And why does one country have a different time than another? The time difference is due to the earth's rotation or the earth's rotation on its axis. Earth rotates 360 degrees in 24 hours, aka in one day. This rotation causes part of the earth to be exposed to sunlight and experience daytime. While the part that is not exposed to sunlight experiences night. It is the things above that cause the time difference in the world. The time difference in Indonesia"Then do all places in Indonesia have the same time or not?" I asked again, curious. The answer is "no." In Indonesia itself, time is divided into three, namely Western Indonesian Time (WIB) which covers the regions of Sumatra, Java, Madura, West Kalimantan, and Central Kalimantan; Central Indonesian Time (WITA), which covers the areas of Bali, South Kalimantan, East Kalimantan, North Kalimantan, Sulawesi, and Nusa Tenggara; and Eastern Indonesia Time (WIT), which covers the Maluku and Papua regions. It's easy like this: If it is 7 am in Jakarta, then the time in Bali is 8 am, while the time in Jayapura is 9 am. So it's not surprising that on New Year's Eve, our friends in Papua will celebrate the new year 2 hours earlier than us in Jakarta.
