Dear Yue,
I guess you just qualified for Junior President.
I will be in the Spa for the rest of the day to work on my rejuvenation.
Just call me in emergencies.

Thank you a lot Christine and TSG and Annachiara and Mare, but I have NO idea what to do as Junior President!! 🫣🫣 But maybe you can give like tasks and that I dont have to speak before a huge group of people! 😵💫😵Go yue go you can do it.. dont mind just do it like the topics you on the forum 😺
I don´t think that there should be too much jobs assigned.
Don`t think/dream too much in old patterns.
I hope for an almost self organising system.
Just like someone wants to learn something
and another one feels experienced enough to help.
I still hope for an atmosphere of love.
Just like Lir_Elhan explained to Yue
in the arrow and flowers post.
It`s worth reading it.
Christine
No dear Mare you are EXACTLY at the right place!! This is PPG University so we learn everything! 🙂 And Lir_Elhan is Professor Gandalf at our super cool PPG University! 🧙♂️Gandalf... is he that old? Hope he is young of mind (and age) But a nice nickname😃
But i like him and wish 😃

Hi everybody! I asked Etienne if we can perhaps have a separate map in Forum for the PPG University! If that is not possible, we can make it nice anyway! 🙂 I let everybody know if I get an answer about it! 🎓🎓Sounds like a good idea😍😺

Prof. Gandalf push up old threads to top like a real magician right now
But maybe it is because to keep special messages. Because other old messages are deleted later if they are too old? I think that is maybe the reason. And a magician is very cool as a teacher in PPG University! 🙂 ⭐🧙♂️
Ok so i wanted to tell that it is not possible to make a new special map in the Forum for the PPG University. 🏫🏛️💒 I asked it but it is not possible. But we can make it nice if we can write in subject like maybe 🎓🎓 PPG University > and the topic. Is that a good idea? I asked a teacher to write a cool lesson! But everybody can write nice lessons because is for all PPG members who like to teach something and everybody can ask questions if they want under the post. 🙇🙇♀️🙇♂️🧑🎓
Maybe it is nice if the post is like about a question or one thing. Like maybe about a Chinese emperor or about a cool thing in space or about like the Islam festival that Arabian Princess wrote about. 👑🕋
Lesson 1 Astronomy: The sun
The sun is the closest star to Earth and is the center of the solar system. The Sun is a medium-sized star in an outer arm of the Milky Way Galaxy. As seen from Earth, the sun is by far the brightest object in the sky; the sun therefore determines the usual distinction between day and night. The sun is responsible for the vast majority of heat in the Earth's atmosphere and is the main source of energy for life on Earth.
The sun is made up of very hot plasma. It contains more than 99% of the solar system's matter, mainly hydrogen and helium. The inner part of the sun is so hot and dense that nuclear fusion occurs: about 600 million tons of hydrogen are converted into helium every second. The energy released is largely emitted in the form of radiation, including visible light. The surface of the sun shows a varying number of sunspots, which are caused by local magnetic fields that inhibit convection.
The Sun is classified as a dwarf star (yellow dwarf). The Sun evolved about 4.6 billion years ago and is now halfway along the main sequence. In a few billion years, the sun will enter its next phase of development. The hydrogen within the solar core will run out, causing the core to collapse under its own weight. The Sun will then increase in heat and size (red giant), engulfing Venus and Mercury and making Earth uninhabitable. At the end of its life cycle, the sun will shed its outer layers (planetary nebula phase) and transform into a white dwarf.
The sun has great cultural and mythological value due to its enormous influence on humans. The sun was and is considered a deity in some cultures: sun gods appear in many different mythologies. The synodic rotation of the Earth and its orbit around the sun form the basis of solar calendars, including the Gregorian calendar, which is widely used worldwide
The Sun is a medium-sized type G main sequence star (spectral class G2V). It has a mass of about 1.989 × 1030 kg (1989 quadrillion tons), equal to 332,946 times the mass of Earth. The sun contains 99.86% of the mass of the entire solar system. This mass consists mainly of hydrogen, in the outer layers about 91 mole percent or 70 percent by mass. The other common element is helium, about 9 mole percent or 28 percent by mass. In the center of the sun, where hydrogen is converted into helium through nuclear fusion, the hydrogen content is probably lower (35 percent by mass) and the helium content is higher (63 percent by mass).
Type G stars are among the 15% brightest stars in the Milky Way: most stars are much smaller (red dwarfs)
