Episode 1: How was quantum mechanics born?

Description: Quantum mechanics is one of the most successful theories known to mankind. But what led to its development? Did it come from a single mind? The first episode of Q and A digs into the past of the beautiful theory.

Episode 2: Why was the Large Hadron Collider Built?

Description: The Large Hadron Collider (LHC) is the biggest machine in the world buried deep down in Geneva. It is 27 Km long and is a marvel of science and engineering. But what does it really do? Why did the scientists and engineers build this machine? The second episode of Q and A answers the question: Why was the LHC built?

Episode 3: What are gravitational waves?

Description: We have known different types of waves for hundreds of years. But in 2015, mankind detected a new form of waves – the gravitational waves. But where did these waves come from? What was the magnitude of these waves and why were they so important to us? In the third episode of Q and A, let us learn what are gravitational waves?

Episode 4: What is dark matter?

Description: Everything you see around is composed up of something we call baryonic matter. But it comprises only 5% of the observable universe – the remaining 95% is dark matter and dark energy. But what is dark matter? Why is it important to us and is there any particle associated with it? In the fourth episode of Q and A, we dive deeper into the mystery of dark matter.

Episode 5: What if Betelgeuse explodes?

Description: Betelgeuse is one of the brightest stars in the night sky – a red supergiant on its deathbed. But what will happen when it explodes? Will we be able to observe it with the naked eye? If yes how bright will it be and does it pose any threat to human civilization? In the fifth episode of Q and A, let us explore the scenario of the supernova of Betelgeuse.

Episode 6: What is Higgs Boson (The God Particle)?

Description: For many years, scientists were trying to understand the origin of mass. They came up with the Higgs mechanism and the Higgs boson, the last missing piece of the standard model. But what it really is? Why we spent around $14 Billion on it and why is it called the God Particle? This is the sixth episode of Q and A.

Episode 7: How Will The Sun Die?

Description: The Sun is the reason behind our existence. It has been burning for the 5 billion years. But just like everything on Earth, even the Sun cannot live forever. It will eventually die. But what will happen when it explodes? Will it become a black hole? What role will the electrons play in its death. This is the 7th episode of Q and A.

Episode 8: What Is Quantum Physics?

Description: Objects in nature have a wide spectrum of sizes: from the smallest quarks to the jumbo quasars. Just like a single medicine cannot cure all the diseases, similarly, a single theory cannot explain everything. The laws used to describe the motion of planets cannot be used to describe the motion of electrons around the nucleus of the atom. This is where quantum physics comes into picture. But what it really is? How is it different from classical physics and why is it so strange. This is the 8th episode of Q And A.
