Dr. Nima Arkani-Hamed gave the lecture over quantum mechanics and space-time in the 21st century. Dr. Nima Arkani-Hamed is a professor at the Institution for Advanced study. He explores how recent research into quantum mechanics promises to shed new light on our understanding of the universe’s fabric of time and space. He also says that relativity and quantum mechanics together create an inheritable universe.
He discuses the dramas of the 21st century one being and end of space-time, gravity, and the other were being limitations of quantum mechanics, cosmology. The questions of why the universe is Big and why it has Big things in it, was also asked in the 21st century. He comments that progress on fundamental concepts take a long time. This is because we are shockingly constrained by what we already know- unlike before the 21st century. Saying it is “almost impossible to monkey around and not be wrong”. This basically means that most of the time when you question these rules you are going to be wrong, but sometimes you will be right.
He also talks about the 20th century redox. This is when he restates that relativity plus quantum mechanics equals the “Quantum Field Theory”. This theory is basically a class of theories that are compatible with both quantum mechanics and relativity. The theories are also extremely constrained. He discuss that we now know that electron structures seem to either be weak or strong, however when you look at the structures at high-energy levels you see that they are the same. These electron structures make up everything because they are just added on to one and another. The particles on these electron structures are actually spinning. In fact these spines come at multiples and the quantum mechanics tells use about these multiples,
Through this lecture I was able to better understand quantum mechanics and relativity and how they work together to create the “Quantum Field Theory”. During the lecture you were able to see how...
