Channel Title: LECTURES FOR SLEEP & STUDY Channel Description: Educational videos about science: astronomy, physics, biology, chemistry, and many others. Feel free to take a nap with the quiet and measured voice of the lecturer 😴 The information will still be deposited in your subconscious while you sleep peacefully and serenely 🌚 QUESTION: Why "SLEEP and study"? Is this disrespectful to scientists? 🧐 ANSWER: If you are not a student, then you most likely manage to listen to scientific lectures only when doing household chores and before going to bed. The channel name would be too long considering all scenarios for using the content. Although the channel title turned out to be a little provocative, we have a deep respect for scientists and science. And if we fall asleep during lectures, it’s not out of boredom, but because in dreams we fly away to distant stars and exoplanets that we won’t be able to visit in real life!
