Introduction! A cryptocurrency is a type of currency which uses digital files as money. Usually, the files are created using the same methods as cryptography (the science of hiding information). Digital signatures can be used to keep the transactions secure, and let other people check that the transactions are real. The first cryptocurrencies were made to be independent of government-issued currencies. Cryptocurrencies use 'decentralized control',[4] which means that they aren't controlled by one person or government. This is different to 'centralized' electronic money and central banks. The control of each cryptocurrency works through a distributed ledger (a list of transactions shared by everyone), usually a blockchain, that serves as a public financial transaction database.Bitcoin, first released as open-source software in 2009, is often called the first decentralized cryptocurrency.[ Since then, over 4,000 cryptocurrencies (sometimes called ' altcoins '

Introduction- Artificial intelligence  ( AI ) is the ability of a  computer program  or a  machine  to think and learn. It is also a field of study which tries to make computers "smart". They work on their own without being encoded with commands.  John McCarthy  came up with the name "Artificial Intelligence" in 1955. More about AI- In general use, the term "artificial intelligence" means a programme which mimics human  cognition . At least some of the things we associate with other minds, such as  learning  and  problem solving  can be done by computers, though not in the same way as we do. [1]   Andreas Kaplan  and Michael Haenlein define AI as a system’s ability to correctly interpret external data, to learn from such data, and to use those learnings to achieve specific goals and tasks through flexible adaptation. An ideal (perfect) intelligent machine is a flexible agent which  perceives  its environment and takes actions to maximize its chance of succ

Introduction/About - A Hyperloop is a proposed type of train that would travel at very high speeds. The reason it can travel so fast is because it is inside a tube with no air. This vacuum means that there will be no friction to slow the train.             ' Concept art of Hyperloop inner workings' The Hyperloop is being created and tested in various places around the world, for example the United States, the Middle East and Asia. Starting- In 2012, Elon Musk (Tesla Motors, SpaceX) proposed this technology. In 2013, he put a plan online that showed the hyperloop train taking 35 minutes to go between San Francisco and Los Angeles in the United States. He shared this technology to the world. In 2015, Musk's company built a 1.6 kilometres (0.99 miles) test tube. He asked universities and companies to make the test trains. They had two competitions in 2017 to see how fast the hyperloop trains could travel. The fastest test was 324 kilometres per hour (201 miles per hour). Advan
