Science and Technology

Where are all the aliens?   Ever since I wondered that, why don't we see flying saucers flitting around? Why don't we see life out there in the cosmos? Frank Drake began searching for alien signals back in 1960 so far, nothing. With each passing year this nonobservation, this lack of evidence for any alien activity gets more puzzling, because we should see them. Best books on science and technology to buy in discount The universe is 13.8 billion years old, if we represent the age of universe by one year, then our species came into existence about 12 minutes before midnight. western civilization has existed for a few seconds. Extraterrestial civilizations could have started in the summer months.  Imagine a summer civilization developing a level of technology more advanced than ours, but tech based on accepted physics. That civilization could program self-replicating probes to visit every planetary system in the galaxy. Intergalactic colonization isn't much more difficult, it...

 Internet of Things (IoT) Network of physical objects that are connected to the internet allowing them to send, receive and exchange data. Now in digital world we can make everything take to each other. We can make our phones talk to each other, We can make Facebook talk to each other. But In the physical world not to much. This is where our lives and technological development kind of stopped. But now we are able to build a network so, multiple of physical objects your chair, your table, your lounge they are connected to the internet. It allows you to send so you can create and transmit, receive so that you can receive and interpret and exchange data, you can have conversation with things around you. So IoT will allow multiple physical objects, like your chair to be connected to the internet. They can send just how good chairs are to other chairs and you. They can receive just how many people want those damn chairs. They can have conversation with other things that are around that...

Science and God Everybody has their own view on reality whether a scientist,, a philosopher or a theologian. You see philosophers and theologians they debate abstract ideas. We wonder what practical impact are they have on our day to day lives.  What I have studied that is God and science are integrated and even more so with the advent of modern science in the last hundred years. It actually helped us make some connections of those seemingly mystical qualities about God. I would like to give three examples to illustrate this. First one is probability, probability in modern sciences is interesting thing. You see pretty much everything has a probability whether it's the normal or really unusual. Let me give you an example of those unusual things. You see if we take a atom again, there's actually a probability that a particle in the atom can leave the atom and at the same time can violate the law of conservation of energy. Now the law of conservation of energy says that energy is ...

 What is 5G and What it can do? Imagine that you are downloading a game on your console. But as many of you know game files are large and may take many hours just to download. Imagine you are in a group video call but because of the latency your call is very laggy and glitchy which destroys the experience you have with the person on the screen. Imagine once more that you are living in a very urban area and because of all the network interferences. You only see one barn phone instead that a perfect five. I will admit that last one it's quite a scary thought for my generation but these are all issues we face and there are dozens of other connectivity problems that plague us every single day. But what if I tell you that there is a solution to this entire problem that instead of waiting hours to download one you could download dozens in under a minute. That instead of dealing with lag on your video chat you can enjoy group calls with your friends without the worry of a connection error...

 How to get your brain focus? A few years ago, I began to observe something in my own behavior that made me a bit uncomfortable. Thar was from the moment I woke up to the end of the day, my life was series of screens. I started the day with the thing that woke up me that is my phone and so I sat there in the bed watching videos on Instagram and bouncing around between the bunch of applications. But then it was time to get up from the bed and cook breakfast, then I focused on the iPad which was kept beside the oven  and then it was time for some work then I focused on a different screen that is my laptop. But there was one particular offender out of all of these different devices that I wasted more time than anything else. That was this dastardly thing: my phone. I could spend hours on this thing every single day. So, I decided to essentially, for all intents and purposes, get rid of the thing for a month. As an experiment I thought " I'm going to live on this thing for just 30...

 The science of friction and its surprising effect on our life The study of friction, wear and lubrication is known as Tribology .   You have all experience all three things. Remember the last time you tried to move heavy object across the floor,  and you could feel something is resisting you? That would be friction. Friction is the force that opposes motion. Wear is loss or transfer of material. It's reason you have to replace your favorite shoes, because eventually the soles disappear. Lubricants are used to reduce friction and wear. They loosen up those stubborn rusted bolts that just otherwise will not budge. But tribology is also defined as the science of interacting surfaces in relative motion. So, interacting surfaces in relative motion: there are lot of those in the world. As you are sitting right now, are you wiggling your foot at all or may be shifting around in your seat? Tribology is happening.  Even the smallest shift in your seat involves two surfaces ...

 The weirdness of water For the last fifteen years, kind of since high school, I have been studying water and I have a secret to tell you: water is weird. It's weird, but it's also fundamental for our lives, and fortunately, 70% of the planet is covered with water. But unfortunately , just 1% is clean water, that is very little. Today, one in six people has lack of fresh water. In the year 2050, it will be one in two people with lack of fresh water. So, the world need fresh water. Now, I am going to tell you that how we can use weirdness of water to get more fresh water. So, you see, water is very important. Let us compare water with another material: with silicon. Silicon is also abundant on the planet, 28% of the earth's crust is composed of silicon. Silicon also has a number of unique properties. The fact that silicon has unique properties and that we have learned how to use these unique properties of silicon allows us today to have cell phones, computers, flat screens a...
