报告人:Frank WilczekNobel Prize Laureate in Physics

 

报告人概况:

 

ProfessorFrank Wilczek is a renowned theoretical physicist. He is the winner of theNobel Prize in Physics and the first permanent member of the National Instituteof Theoretical Physics, National Science Foundation. He harvested fruitfulachievements in the field of scientific research, which have greatly promotedphysics research process. He is the creator of the "axis", theinheritance of quantum chromodynamics, and found the progressive freeness inthe normative field theory, and in the study created a new quantum statisticaltheory that any sub-theory. In addition, Professor Frank Wilczek and otherthree American scientists in the quark particle theory made a majorbreakthrough in helping science to achieve "for all things to buildtheory", making a big step forward.

 

报告内容概况:

 

Theorigin of quality is a profound problem in physics, seemingly simple, butessencial. The most basic attribute of quality in classical mechanics is thatthe total mass is the sum of the individual masses. This assumption is so deeplybelieved that there is no definite law to define the quality of the primitiveconcept. With the development of physics, the definition of quality is furtherexplored. The famous qualitative formula of Einstein's special theory ofrelativity is usually written in the form of E = mc2, which reflects ourprejudice in terms of quality. But the equation can also be rewritten in theform of m = E / c2, which implies the possibility of interpreting the qualitywith energy. In the modern particle accelerator, the equation m = E / c2becomes a reality. In the study of electron collisions, scientists have foundthat when a high-energy electron collides with a high-energy positron, we oftenobserve that a large number of particles will be produced afterward, and thetotal mass of these particles may be the original electron and positron mass.In this way, we create the quality in the real world by energy. The daily workof the forefront of modern physics is often dealing with complex concepts andextreme conditions. We talk about quantum field and quantum entangled superpair. However, this complex work sometimes gives answers to the naive questionsabout what we are familiar with, and this is the wonderful content which ourguest is going to show. Let us follow Professor Frank to experience themysteries of the origin of quality.
