Scientific American: Black Holes, Quantum Entanglement and the No-Go Theorem

Today I read an article about Quantum computers. They said quantum computers have problems that may never be able to be solved. Suppose I have a note that I want to throw away and Bob has particles that are entangled with particles of the note. If I toss it into black holes, the note will destroy but Bob have

The Nobel Prize in Physics 2021: Popular Information

Nobel Prize Selection Committee publishes a detailed explanation of the Nobel Prize every year called popular information. This time, I read about the Nobel Prize in physics in 2021 so, I'll introduce some information. This is the link to the document https://www.nobelprize.org/uploads/2021/10/popular-physicsprize2021.pdf The article raises three greenhouse gases carbon dioxide, methane, water vapor, and the strongest influence for global warming is water vapor, but it is impossible for us to stop emitting water vapor, while we can control carbon dioxide. The amount of water vapor in the atmosphere depends on how temperature there is so, the higher temperature is, the more water vapor is contained in the atmosphere. If more carbon dioxide emits into the atmosphere and makes it warmer, more and more water vapor is contained in the atmosphere and makes it even warmer. This is bad circulation. Suddenly, some people say that rising temperatures recently have been caused by that solar r...

The Nobel Prize in Physics 2020: Popular Information

In the last blog, I introduced popular information about physics in 2020, in this blog, I'm going to write about popular information about physics in 2020. This is the link to what I want to write  https://www.nobelprize.org/uploads/2020/10/popular-physicsprize2020-1.pdf . The Nobel prize was given to two fields and three persons. ROGER PENROSE won The Nobel prize for the discovery that black hole formation is a robust prediction of the general theory of relativity, and REINHARD GENZEL and ANDREA GHEZ won The Nobel prize for the discovery of a supermassive compact object at the center of our galaxy. What is the Black Hole? Einstein announced General Theory Of Relativity from 1915 to 1916. In general theory of relativity, one numerical formula called Einstein's equation has described some phenomena. Blow is the Einstein's equation \[ G_{\mu \nu} + \Lambda g_{\mu \nu} = \kappa T_{\mu \nu}  \] It seems simple but when we describe Einstein's equation, we u...

The Nobel Prize in Physics 2018: Popular Information

INTRODUCTION In the last blog, I introduced popular information about physics in 2018, in this blog, I'm going to write about popular information about physics in 2018. This is the link to what I want to write  https://www.nobelprize.org/uploads/2018/10/popular-physicsprize2018.pdf The prize reasons for the Nobel Prize in Physics in 2018 are for the "optical tweezers and their application to biological systems" (ARTHUR ASHKIN) and "for their method of generating high-intensity, ultra-short optical pulses"(GÉRARD MOUROU and DONNA STRICKLAND). To say in the field of physics, their research field is OPTICS. ARTHUR ASHKIN's Achievement Simply speaking, his achievement is to invent optical tweezers that the method of holding very small materials such as ranging from in size atoms and molecules to viruses and cells. Sun Ray carries enormous energy to the earth, in the age of just inventing laser beams, some people started thinking about whether it would be possibl...
