Quantum coin flipping uses the principles of quantum mechanics to encrypt messages for secure communication. It is a cryptographic primitive which can be used to construct more complex and useful cryptographic protocols, [2] e.g. Quantum Byzantine agreement .
In Discord, slash commands are used to send special messages and execute commands, like sending a shrug emoji (¯\_(ツ)_/¯) or a table flip emoji ((╯° °)╯︵ ┻━┻), or changing one's nickname using "/nick". Slash commands can also be used to use Discord bots.

A chatbot (originally chatterbot) [1] is a software application or web interface that is designed to mimic human conversation through text or voice interactions. [2] [3] [4] Modern chatbots are typically online and use generative artificial intelligence systems that are capable of maintaining a conversation with a user in natural language and simulating the way a human would behave as a ...
The outer coin makes two rotations rolling once around the inner coin. The path of a single point on the edge of the moving coin is a cardioid.. The coin rotation paradox is the counter-intuitive math problem that, when one coin is rolled around the rim of another coin of equal size, the moving coin completes not one but two full rotations after going all the way around the stationary coin ...
