Strange but true that china is going to launch their own artificial moon by 2020 that will light up the night skies and urban areas. This artificial moon like satellite will replace the streetlamps and lower the electricity costs in urban areas, according to China Daily a city in south western Sichuan Province, Chengdu is developing artificial satellite which will shine with the real moon in the sky but eight times brighter.  The first man-made moon or artificial moon will be launched from Xichang Satellite Launch Center in Sichuan, with three more to follow in 2022 if the first test goes well.   Though the first launch will be for experiment purpose only, the artificial moon that they will launch in the year 2022 will be the real deal with great civic and and commercial potential.   But how will this artificial moon work. Well the answer is pretty simple, this artificial moon will work exactly like our real moon works. It will use the light coming from the Sun and will r...

This is really freaking cool to know that Nasa's Parker solar probe is going to touch the Sun and going to study it from a very close distance. This mission is not only about getting to know our Sun but also to know a lot about how other stars work. But the real question is how this probe will be able to travel such a huge distance and how will it be able to fly through million degree plasma and won't melt.   The distance of Earth from Sun is 149.6 million km and in this case Nasa's Parker solar probe will reach as close as 6 million km from sun's surface. Many of you may or may not know that it will become the fastest ever human made object. And it is set to travel around 692000 km/h. On earth that would be like going from Washington D.C. to Tokyo in less than a minute.   But what makes that spacecraft so speedy? Actually it is entirely due to the gravity of Sun. The probe will go so fast because when it will reach so close to Sun it will turn off it's own speed an...

To understand the concept of quantum computer and quantum computing you first should have a little knowledge about the quantum mechanics because this type of computers use quantum mechanical phenomena.   So first of all lets jump into the topic what quantum mechanics is. Many of you may or may not know that this topic is related to subatomic particles, their motion, their interaction, mathematical description of motion of these subatomic particles etc. Quantum mechanics also known as Quantum physics or Quantum theory.  This part of physics deals with very small particles and the science related to them. Some theory that classical science or physics could not explain, this modern theory of physics can easily explain.   As an example light behaves like both particle and wave. Only with quantum physics you can show that light behaves like a particle that is PHOTONS. A single photon is a quantum or smallest observable amount. Now i hope you have a little bit knowledge about q...

Barcode is basically a machine readable code, you might have seen it many times on different products or commodity bought from a shopping mall. It looks like a pattern of different lines of different width and some numbers below the line, yes it is the barcode. Barcode is used for stock control. There are many useful sides of barcode we will discuss in this article and will tell you how does this actually work. In a very busy store it is very important to keep track of all the things that are being bought and to make sure it is always available in stock. There are two different ways how a store keeper can manage it, one is by doing it manually and the second is he could write it down at the time of customer's checkout. The second way is easier than the first one. And Yes barcode technology can help in such conditions. With barcode price can be changed as frequently as the shopkeeper wants. There is an another possibility of things being stolen in a large busy shop, in such cases ba...

You might have heard many times that many electronic goods got damaged due to water, as many of us know that water drop causes short circuit in electronic components. But what if i say that though water causes damage in electronic goods still you can wash electronic components PCB motherboard etc with water.   But before getting into our today's topic first learn what this term SHORT CIRCUIT is ?? Short Circuit means a bad electrical connection that causes the current to flow in the wrong direction. But why water causes short circuit ? If you recall your school days you have learned that water is conductive means electricity can travel through water. Though pure water is not conductive at all but most of the water that we see actually not pure water. The impure water is actually conductive and causes Short Circuit in different electronic boards.   When a water drop or lots of water ( not pure water ) comes in contact with any electronic circuit then due to it's conductive natu...

Different earbuds or headphones are not the actual problem, the real reason that harms you is sound. Today in this article we will discuss on why it is not good to use headphone for long. You can see people using headphone everywhere, no matter you are on a bus, train, metro or road if you look around you can see many people are using headphone for hours. But trust me they are not even aware of what problems they can face in near future. Overuse of headphone or earbuds can cause permanent hearing loss. There should be a limit of everything you do, misuse or overuse always causes problem.   Technology has both good and bad sides so you should always remember one thing that if you use it in an improper manner it would always give you trouble.   Below in this article i will tell you some of the problems you can face if you overuse Earbud or Headphone everyday.   1. Permanent Hearing Loss: If we listen to music on a high volume ( higher than 90 decibels ) then it might cause ...

If you search this topic on google you might find the answer that no we don't need an antivirus program in our smart phones, even if you search this topic on Youtube most of the Tech Channels will provide you the same answer that no we don't need an antivirus program in our smart phones. They just told you not to download applications from any unknown sources or told you to turn off the settings INSTALL APPS FROM UNKNOWN SOURCES but is that enough ??   Now my question is if we turn of the above settings or if we do not download anything from any unknown sources does that give us full protection against future malware attacks? No it simply do not give us full security from future attacks but yes if we do not download anything from any unknown sources it reduces the possibilities of malware attacks.  Malware, Spyware, Virus, Trojan can be spread from one phone to another phone through USB pendrives, messengers like whatsapp or facebook etc and it is very hard to detect them manu...
