When we talk about infinity  ∞ , we talk about the existence or something so large or so tiny, it's impossible to imagine. But ironically, we've done just that. Imagine you take a bag of salt and tried to count how many grains of salt there is in it, you'd say it's impossible because it feels so infinite. Well, that analogy hasn't even begun to scratch the surface of the concept that is infinity.  Infinity is imaginable yet so complex to understand. It took years before mathematicians could first understand what infinity is. It is not a number! It's is more like an abstraction . Some people define it as something that is so large and limitless. But that's not all true. You'll see why later on. We Have Infinities Are you a science enthusiast? If so, you'd have probably heard of a theory of multiple universes that makes up the multiverse. If not, click here . The theory that makes room for the possibility of a multiverse infers we...

Temperature, what is it? Is it heat? Or is it Cold? Well, it's both of them. From childhood, we learned that temperature is the degree of hotness or coldness of an object. This definition is still true. Well kind of. For a fact, the temperature isn't just a degree. It is actually the average energy of all the particles in a system and it's also related to the distribution of those energies in the system. You see, a change in temperature is basically a consequence of heat exchange. This results in a rise or fall in a body's hotness or coldness. So what does it mean when the temperature is said to be absolute? Absolute - Maximum If you're thinking it means 0 degrees Kelvin, you are slightly incorrect. That is just a point on the temperature scale. What it actually means is a point where we can go no further. This applies in both directions. So we have what is called Absolute Cold ( better known as absolute zero) and Absolute Hot....

Imagine a world where you could talk to a robot, chat with it, tell it to do something? Oh wait, we already can but not to a level we truly want. The Definition and Concept Computers have been in existence since 1975 (computers with real power that is). Powerful as they are, they become undone when it comes to real life situation. Let me explain. Digital computers are based on binary states of 0s and 1s (or ON and OFF). It can make powerful computations at mind-blowing speeds but that's about it. It can do only what it is programmed to do and nothing else. It has a very rigid predefined set of instructions that directs it to start and complete a task. This could be somewhat limiting! When it comes to real-life situations, the ball game changes as almost nothing is predictable. It requires the ability to observe and take the appropriate actions accordingly. This is where Artificial intelligence (AI) comes into play. Artificial intelligence is a littl...

Since the beginning of time, humans have had an insatiable desire to explore. Curiosity is one of our greatest strength and it is seemingly what's responsible for the immense and exponential technological advancement we see today. As we become more populated, we seek more resources and places to live in. The space program comes into play here. We've done all this on our little planet. Now imagine the things we could achieve with two planets at our disposal. The planned trip to Mars will most likely make that dream a reality. But wait, is it only Mars that exists in our solar system? Have you ever wondered why we chose Mars, our neighborhood planet, to live in? If so, let's find out why? First, on making a list of probable habitable planets and taking other celestial bodies into consideration we can narrow them down to just three: Venus, Mars,  and Titan ( Saturn's own moon). Let's break it down and see why Mars is the most logical. Venus: Alm...

From the incredibly tiny to the amazingly big, there has been quite a number of theories made to explain the behavior of matter in our world.  During Isaac Newton's time, he released a book titles "Principia" which accurately describes the motion of matter. It is usually referred to as Classical physics. This was used for decades to explain the behavior of matter on most scales and it's still implemented till today. Then come 1905, Albert Einstein, in his radical and creative mind discovered a new way to look at physics of motion. You see, Newton's classical physics describes motion with respect to only one frame of reference which remains constant in every situation but this didn't sound so logical to Einstein so he decided to think outside of the box and what he got from doing that was Special relativity. Now unlike classical physics, special relativity takes into consideration the various frames of references with respect to the observer...

The universe we live in is like an artwork, carefully and precisely crafted in place with a touch of an equal proportion of beauty and anger. Thinking about the immense size of the universe is just mind-blowing. We all are so incomparable in size to the universe. But how did it get so big? Origin of the Universe For so long as humans pondered on how the universe was created. Religiously, it is said that a higher and supreme being created this world. However, from a scientific point of view, the universe can be traced back all the way to an event called the Big Bang. Hot, dense, tiny, powerful, etc, just a few attributes of the catastrophic yet necessary event that made this universe. Now the big bang is somewhat of a misconception of the event. The creation of the universe was neither big nor created a bang. Then what was it and why was it then coined with the term Big bang?  The Big bang was simply the point in time when all the matter in the univers...

Glorious! Mankind progress that is. We continually strive for greatness in the most courageous way possible. We've come so far and we're not relenting in any known way. Technology is at the frontier of mankind's development as it opens new doors for all other possibilities.  By Jeremy Hsu on December 6, 2018              As we know, we entered what was called "The Space Age" at the launch of the first rocket into orbit. Since then, we've gone to the moon and back and are preparing to go to Mars in the coming years. How is it possible for mankind to have pushed so much in so little time?            Let's move to computers for example. The first computer built by a Charles Babbage normally referred to as the father of the computer. Though it was a milestone needed for the continued survival of mankind, the piece of machinery he invented was extr...
