Kapag ang Iyong Anak ay bilang Big bilang mo,en

My mom used to say that when your child is as big as you, you have to treat them with respect. What she actually said was that you had to address them using a respectful form of “sa iyo,” which doesn’t make any sense in English, but may work in Hindi or French. It worked poetically well in Malayalam. I was reminded of this maternal pearl of wisdom recently when I was watching a movie with my son.

I am attending a research retreat on mindfulness and contemplative practices at the beautiful Garrison Institute. I am learning a lot of interesting things, and meeting a lot of like-minded and excellent people – the kind of people with whom I could have deep conversation about the unreal nature of reality, unlike most people from other walks of life would politely and tactfully excuse themselves when I get a bit unreal.

Twilight Years

At some point in our life, we come to accept the fact we are closer to death than life. What lies ahead is definitely less significant than what is left behind. These are the twilight years, and I have come to accept them. With darkness descending over the horizons, and the long shadows of misspent years and evaded human conditions slithering all around me, I peer into the void, into an eternity of silence and dreamlessness. Ito ay almost time.

Interpretation of Special Relativity

When we looked at Quantum Mechanics, we talked about its various interpretations. The reason we have such interpretations, Sinabi ko, is that QM deals with a reality that we have no access to, through our sensory and perceptual apparatuses. Sa kabilang banda, Special Relativity is about macro objects in motion, and we have no problem imagining such things. So why would we need to have an interpretation? The answer is a subtle one.

Bilis ng Banayad

The speed of light being a constant sounds like a simple statement. But there is more to it, quite a bit more. Let’s look at what this constancy really means. Sa unang tingin, it says that if you are standing somewhere, and there is a ray of light going from your right to left, it has a speed c. And another ray of light going from left to right also has a speed c. So far, so good. Now let’s say you are in a rocket ship, tulad ng ipinapakita sa figure sa ibaba, moving from right to left.

Special Theory of Relativity

Kapag marinig namin ang tungkol Einstein at ang mga espesyal na kapamanggitan (o ang espesyal na teorya ng kapamanggitan, upang gamitin ang mga tunay na pangalan), sa tingin namin ng sikat na E = mc^2 ekwasyon, at kakaiba mga bagay tulad ng mga twin kabalintunaan. Habang ang mga bagay na ito ay ang lahat ng tunay at mahalagang, ang problema SR sumusubok upang malutas ay isang ganap na iba't ibang mga isa. Ito ay isang pagtatangka upang ipagtanggol ang isang pangunahing prinsipyo sa physics.

Quantum Field Theory

In this post on Quantum Mechanics (QM), we will go a bit beyond it and touch upon Quantum Field Theory – the way it is used in particle physics. In the last couple of posts, I outlined a philosophical introduction to QM, as well as its historical origin – how it came about as an ad-hoc explanation of the blackbody radiation, and a brilliant description of the photoelectric effect.
