I just finished my first term as a professor at Singapore Management University. I taught an undergraduate course called Computer as an Analysis Tool, which is on business modelling and data-driven decision support. I had about 130 students, in three sections of three classroom hours each per week. I have to say the whole thing was a very enriching experience. Natuurlik, the reasons behind this statement will be expounded on, theorized and hypothesized – this is Unreal Blog, na al.
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. Dit is almost time.
Onderrig is 'n edele en lonende beroep. As my sunset career, I have accepted a faculty position at Singapore Management University, onderrig data analise en sake-modelle by die Skool vir inligtingstelsels. Hierdie onderwerpe sit goed met my entrepreneurial ventures from earlier this year on data analytics and process automation, wat al 'n deel van my uit te kom van aftrede was.
Sedert die post-reeks op deeltjies en interaksies het 'n bietjie langer as wat ek wou, Ek het gedink ek sou dit op te breek. Kom ons begin met 'n herhaling van die moderne fisika wat jou sal benodig om die struktuur van materie te verstaan.
When we looked at Quantum Mechanics, we talked about its various interpretations. The reason we have such interpretations, I said, is that QM deals with a reality that we have no access to, through our sensory and perceptual apparatuses. Aan die ander kant, 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.
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. Met die eerste oogopslag, 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, soos getoon in die figuur hieronder, moving from right to left.
Wanneer ons hoor van Einstein en die spesiale relatiwiteit (of die spesiale relatiwiteitsteorie, om die regte naam te gebruik), Ons dink aan die beroemde vergelyking, en vreemde dinge soos die tweeling paradoks. Terwyl hierdie dinge is almal ware en belangrike, die probleem SR probeer om op te los is 'n heeltemal ander een. Dit is 'n poging om 'n basiese beginsel te verdedig in fisika.
