The question that came across everyone’s head at least once in their lifetime: “Is there other life out there?” Regardless, the next question is how do we communicate with extra-terrestrial life? How would you solve this dilemma in the 1970s? Well, scientists back then came out in my opinion, with an ingenious idea to reach out to others: The Golden Record. 

Astronomy studies celestial objects and phenomena. When doing astronomy, we want ways to state the location of celestial objects through coordinates. The way we usually do this is by projecting the sky onto a large sphere centered around the viewer. This is an imaginary sphere called the Celestial Sphere. If we want to talk about the distances on this sphere, we can do this by measuring the angles. This is like a three-dimensional version of the polar coordinate system in two dimensions.

There are two main types of wind instruments: brass and woodwind. These instruments are classified by the way the sound is produced, not what material they are made of. Woodwind instruments are played with a reed attached to a mouthpiece. The reed is a thin cut piece of cane, a plant similar to bamboo. The reed is placed on the mouthpiece and clamped with a ligature, revealing a slit between the mouthpiece and the reed.

AI isn’t a new idea to us, in fact, it has been put forward since the last century. People have already used AI in many different areas including their reactions to people’s behavior. For example, Siri is a quite smart AI because it can deal with many kinds of requests, and it’s becoming stronger. An AI similar to Siri possesses different abilities, the first one is that it can understand you. The ability to transfer spoken words to text is more than important for an AI since it’s annoying for people to enter what they want to do to a computer.

In the whitepaper of Bitcoin, “Bitcoin: A Peer-to-Peer Electronic Cash System”, Satoshi Nakamoto proposed the Blockchain protocol. It combined several avant-gardes ideas of Cypherpunks and other groups who focused on the development of a digital currency system in the late 20th century.

Supply Chain Finance (SCF) is an effective method to lower financing costs and improve financing efficiency and effectiveness, and it has gained research momentum in recent years. It has always been considered in need of financing and provides further insights for future research by doing some preliminary work on a unified model. Specifically, I consider a case relevant to current COVID-19 by depicting a supply chain with external shock and I achieve a unified case by considering multiple parameters of interest.

In mathematics, Pascal’s triangle is a triangular array of the binomial coefficients that arise in probability theory, combinatorics, and algebra. In simple words, it is a triangle of numbers where each number is the two numbers directly above it added together (except for the edges, which are all “1”).
