Overview of a Simple charge model using which we were able to develop the whole theory of electromagnetism.
We discuss how we don't know what charge really is but we know that it is a property of materials. It is NOT an object. It is a property like mass. We find that rubbing produces charge and there are 2 types of charges. One is called as Positive and other is called Negative charge. Like charges repel and unlike charges attract each other.
So, based on this we can develop a very simple charge model:
• Rubbing produces charge
• Test of charged object is that it attracts neutral objects
• Charge can be transferred via contact
• There are two kinds of charges. Like charges repel and unlike charges attract each other
We find that source of charge is buried deep inside the atom. Atom has a nucleus at its center and nucleus has two types of particles: protons and neutrons. Outside the nucleus, in some kind of a cloud, you can find the third type of particles: electrons.
When we discovered these particles, we found charge on them too. We found that protons have positive charge and Electrons have negative charge. Transfer of electrons is responsible for producing charge during rubbing.
We also see how materials are divided into two categories. 1st category is of materials like metals in which charge can move and they are called as conductors. 2nd category is of materials like plastic, wood, glass, rubber, pure water etc. through which charge cannot move and they are called as insulators.
We also discuss a very non-intuitive phenomenon of polarization, which explains attraction of neutral objects like pieces of paper towards both positively and negatively charged objects.
Finally, we also discuss charging by induction, discharging and grounding.

This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥
Origins of the Idea 🌱
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠
Challenges Faced 🤔
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍
Creating Truly Random Links 🛠️
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
About YouTube 📺
YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟
Content and Users 🎵
Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.
While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.
Monetization and Impact 🤑
YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.
As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
