Humanity has been in awe of the wondrous heavens since time immemorial. The ancients saw the sky as a reflection of their world, and they often looked upward to find meaning in their lives and even try to predict the future. In the spirit of understanding the sky, planetaria were developed as a way of sharing the majesty of the night sky with the general public.
Do you know where your energy comes from? Not just the energy that powers your appliances, but every facet of your life. From the food you eat, to the fuel in your car, to the electricity in your home, energy moves everything in our lives. That should come as no surprise, but what you may not know is that our energy has a time limit. Rather, the location and distribution of energy changes over time. This is known colloquially as the second law of thermodynamics, the law of entropy. The first law states that the total energy in the universe is constant, and therefore energy cannot be created or destroyed, it can only change forms. Thanks to the understanding of these laws, humans have been able to industrialize their lives in ways unimaginable just a few centuries ago. But as a law of nature, entropy affects every aspect of our lives, not just the things we use switches on. So no matter what your profession is—or whether you ever took a basic science class—it pays to understand how it works.
We live in an age where college degrees are a dime-a-dozen, jobs are scarce, and opportunities seem limited. But change is the nature of the universe, and when one door closes another one opens. We all know this, but we also know that finding our path in life is like walking in the dark.
Growing up, many of us probably remember a time when our parents were the smartest people in the world. They knew the solutions to all our problems, and they could take on any situation. But eventually, we began to realize that they didn't have all the answers. In our rebellious teenage years, we likely realized that not only were they occasionally wrong, but more often than not they told us to disregard their errors, and take their opinions as valid prima facia. However, despite how young people often see adults as authoritarians, their life wisdom more often than not proved them correct when it really counted. Finally, when we become adults ourselves, and the people who have guided our lives have grown old and grey, it finally dawns on us. Those adults were just like we are, and nobody really knows exactly what they're doing.
My words tremble. It is said that Zen is a topic which words cannot describe in full, for it describes the nature of being. For those who speak do not understand, while those who don't know, truly understand. In that sense one who claims to know what Zen is can be said to be a fraud, like someone who picked your pocket and sold you your own watch. You already understand Zen, although many of us feel lost.
The history of the universe is a history of constant change. However, while its state and appearance has changed drastically over the course of its 13.82 billion years of expansion, certain key things have remained unchanged. For one, the laws of nature have stayed constant throughout time and space, for every cubic planck-length of the universe.
