Top-5 tech at CES 2017 (Consumer Electronics Show).

CES is here. My personal favourite… In case you didn’t notice, CES 2017 is the 50th consumer electronics show! Over the years, most of the new technologies and gadgets that rule the rest of the year originates from CES. Of course MWC(Mobile World Congress) and WWDC(World Wide Development congress) awesome too and also plays a major part. For now let’s talk CES, it is held every year in January.

Here’s my favourite tech on CES!

In my view, this year CES was all about VR (Virtual reality), AR (Augmented reality), AI(Artificial intelligence), IOT(Internet of things), TVs, Self driving cars and a lot of smart phones related stuff! Most of the gadgets introduced in CES 2017 falls in one of these categories.

  1. The displays are really crazy this year. LG OLED W-Series  is my personal favourite maxresdefault-1-35

Just look at it! It is so thin that, it just sticks to the wall like a poster… Well, the speaker for the TV are separate.

All the other displays are mind blowing too… The TV by Samsung, Sony, Amazon etc…

2. The processors, the Qualcomm’s all new Snapdragon 835 processor was introduced. Intel’s new Lake 7th generation intel core processor.

3. The smart bed called “Sleep Number 360”, this was actually cool. This intelligent bed does so much…

Look at it for your self…

4. Obviously a bunch of new laptops and smartphones. Blackberry’s new smart phone “BlackBerry mercury”, this has an amazing built. Asus’s new AR smart phone, this comes with snapdragon 821, Google’s tango technology and the first phone to come with 8 GB RAM.

5. Razer’s Project Ariana is an extension of the gaming company’s Chroma lighting setup. Rather than just brightening up a keyboard, this 4K projector expands your game outside of a monitor. It’s pretty trippy, and unlike Microsoft’s similar IllumiRoom concept, Ariana will hopefully be a shipping product by year’s end. The Razor’s Roccat mouse and also the 3 monitors containing laptop…

Hurrah! My blog turns an year now…

Hurrah! It’s been an year now. One thing’s for sure, blogging community here is awesome. I learnt so much here. Now, my blog turns an year and I got an year of experience in blogging. This is a huge thing to me. So, I thought, why not make this article a huge one too. Before you get mad at me scrolling down and down and wondering where it ends, let me explain you something.

When I did my 100th article with 100 followers (Celebrating 100th article with 100 followers). I thought I would write my 200th article with 200 followers but, it didn’t happen now. This is my 153rd article with 210 followers;);) The funny thing is I got the followers count, as I said before  bloggers here are really awesome, but I didn’t reach my articles count;);) It’s pretty genuine though, you don’t want to read junk and I don’t want to write articles to just satisfy the count.

Moving on, as you scroll down, hopefully you find some really interesting articles. And there are so many of them. Trust me you won’t be disappointed because, all my favourite articles are listed below. The good thing is, almost all of my articles are listed. Favourites till my 100th were listed in one article and from 100th to this particular article are listed below. So, this is an eye feasting article, atleast to me;)

If you have read and still remember my 100th article you might have noticed that, a few dialogs are similar right? Yeah! In case you don’t reach the end of this article reading and scrolling, let me tell you something. Thank you so much for making this happen, thank you for your support and thanks for your suggestions. Appreciate it!

What’s Li-Fi? How’s that 100 times faster than Wi-Fi?


Scientists achieved speeds of 224 gigabits per second in the lab using Li-Fi!! This technology changes everything about the way we use the Internet.

And now, scientists have taken Li-Fi out of the lab for the first time, trialling it in offices and industrial environments in Tallinn, Estonia, reporting that they can achieve data transmission at 1 GB per second – that’s 100 times faster than the Wi-Fi used on this day.

Let’s see how this thing works?

lifi-technology-in-wireless-communication-13-638

The technology uses Visible Light Communication (VLC), a medium that uses visible light between 400 and 800 terahertz (THz). It works basically like an incredibly advanced form of Morse code – just like switching a torch on and off according to a certain pattern can relay a secret message, flicking an LED on and off at extreme speeds can be used to write and transmit. These flicking light falls on a receiver which interprets the data (interpret in the sense the particular number of blinks per second has a significant data like a number or a word)

And while you might be worried about how could we feel comfortable with all that flicking, don’t worry – we’re talking LEDs that can be switched on and off at speeds imperceptible to the naked eye.  The frequency will be extremely high.

There are so many advantages with Li-Fi over Wi-Fi. One of those advantages is, the data will be secure, unlike Wi-Fi where the radio waves passes through walls, in Li-Fi the light cannot pass through walls so data cannot be accessed by anyone else the other side. Which also means there’s less interference between devices.

Don’t get hurry searching the internet to order a Li-Fi connection;). Our homes, offices, and industry buildings have already been fitted with infrastructure to provide Wi-Fi, and ripping all of this out to replace it with Li-Fi technology isn’t particularly feasible, so the idea is to retrofit (add to something that did not have it when manufactured) the devices we have right now to work with Li-Fi technology.

If you wanna learn more watch the video specified above, where the man who invented Li-fi explains and demonstrates what Li-Fi actually is.

So, let me know, what do you think.

 

Extinction of DINOSAURS!! Is Dark matter responsible??? 

One of the many theories on dinosaurs extinctions was according to the book “Dark Matter and the Dinosaurs,” by a physicist Randall released on Oct. 27, Precisely Randall’s theory states that this Dark matter, with its gravity, pushed some of the huge masses on to the earth which caused the extinction🙄🙄…Oh wait, what’s Dark matter now?

It is believed that majority of our universe is occupied by Dark matter… We can’t actually see the dark matter, we can only feel the gravity of the dark matter.. Learn more about Dark matter here ….. Dark matter

Well.. There isn’t an exact and accurate theory for this.

 According to extraterrestrial impact theory, on testing a few rocks it was found that extinction event is rich in the metal iridium. This layer is found all over the world, on land and in the oceans. Iridium is rare on Earth but it’s found in meteorites at the same concentration as in this layer. 

This led scientists to postulate that the iridium was scattered worldwide when a comet or asteroid struck somewhere on Earth and then vaporized. A 110-mile-wide crater carved out of Mexico’s Yucatán Peninsula, called Chicxulub, has since been found and dated to 65 million years ago. Many scientists believe the fallout from the impact killed the dinosaurs.

But there is some other fact which contradict this theory….

Earth’s core is also rich in iridium, and the core is the source of magma that some scientists say spewed out in vast, floodlike flows. This volcanism has also been dated to about 65 million years ago.

So, research is still going on… Let me know your theory on the extinction of DINOSAURS..

TELEPORTATION?

Teleportation is nothing but converting matter into data, transport that data to a desired position and reassemble it. The very first teleportation was done back in 1998. A photon was teleported one meter. This whole teleportation thing works on the principle of Heisenberg Uncertainty Principle ( it tells that we can know speed or position of an object but not both) ,  with this we developed a theory called “QUANTUM ENTAGLEMENT”, learn more about it here Quantum entanglement. This principle tells that any two entangled particles are connected where ever they are in the universe. So, to teleport a photon we need two entangled photons.

  1. Photon A: The photon to be teleported
  2. Photon B: The transporting photon
  3. Photon C: The photon that is entangled with photon B

By entangling photons B and C, researchers can extract some information about photon A, and the remaining information would pass on to B by way of entanglement, and then on to photon C. When researchers apply the information from photon A to photon C, they create an exact replica of photon A. However, photon A no longer exists as it did before the information was sent to photon C.

Well… Till date we were teleporting only photons, but in a human body there are 10^28 atoms.. According to the researchers a human body consists of 3.02*10^32 gigabytes, which might take like forever to teleport, by the way what’s your internet speed? ;);).

There is another problem!!!!

Here comes a clash between the science and philosophy because to teleport matter, matter needs to be converted into data which indirectly means to destroy it first. At this time we were successful in teleporting photon and a few atoms like Cs and Rb. But What if in near future we find a way to teleport actual molecules, even organic molecules, in turn teleporting a real human. To teleport first we indirectly destroy the initial object right, only then the object is converted to data and teleported with all the exact same features and memories as the initial object, then what happens to the soul we all believe in, and the teleported human is actually dead??

Let me know your thoughts… It feels great to be back..

One of the worlds longest running science experiments ( Pitch drop experiment)

Pitch_drop_experiment_with_John_Mainstone

Very long ago (85 years) Pitch drop experiment was started and this is still running. Yeah, you read it correct ( still running) you can even watch it live right now. Here’s the link Live herelive Before you head on to watch it live, let me tell you a brief short story of this longest running experiment.
The experiment’s creator was Professor Thomas Parnell, the first professor of physics at The University of Queensland. In 1927 he setup the experiment to demonstrate the viscosity of pitch – the thickest fluid known to exist.

Professor Parnell heated some pitch and poured it into a glass funnel, then left it to cool for three years. In October 1930 the bottom of the funnel was cut and the pitch began to flow.

It took eight years for the first drop to fall. The next five drops each took seven to nine years to fall, with the sixth drop falling in April 1979.

IMG_2824
Till date no human watched a drop falling.

Well… Yeah the funny thing is the creator of this experiment missed that event two times. The first time few minutes before this rare event, he went for a coffee. The second time he was very determined to Watch it and fixed cameras to capture everything but ironically the camera failed just before the event.

Finally he permanently fixed 3 cameras and started a live telecast on the Internet.

And recently the camera captured the drop fall… Here’s the video. And the tenth drop was expected to fall in 2020.

TIME KEEPING… LEAP SECOND???

what’s a leap second?

The time it takes for earth to rotate around the sun actually isn’t consistent, it differs few fractions of seconds. This is the reason why we add leap seconds once in a while. Recently on june 30th 2015 we added a new second.

Time keeping!!

So, we created the time. We can’t actually sense time with our senses. Learn more about the nature of time right here Nature of time. So, Before we talk about time keeping which is so long indeed, let’s quickly see

Since ages we humans are trying to make time more and more accurate. So let’s get to the history, in 3500BCE Egyptians started measuring time using sun. By placing a tall stick or something, which casts shadow in a particular place according to the suns position. But this isn’t accurate because this doesn’t work on a cloudy day and this changes the durations according to the season change.

So, to overcome this problem “Mechanical clocks” were built. As the time is calculated based on a relative change, these clocks also work on the same principle “Measuring time using a repeated process”. The first in that kind were Water clocks, which measure time according to the volume of water dropped at a constant rate in a marked container. And these mechanical clocks became sophisticated and we started using notched wheels for the constant movement but there was a problem in regulating the speed of the wheel. Now here come the concept of Pendulum. Galileo in 1600 studied the motion of a pendulum, which states that no matter what the mass of the pendulum is, it makes back and forth motion rate constant depending on the length of the pendulum. And this concept was used to build a pendulum clock.

These pendulum clocks were great, but these clocks were a problem to the sailors who often were on the moving ships. To solve this problem John Harrison invented a pocket clock which works on a spring mechanism.

After a long gap, in 1960 Quartz clocks were invented. Quartz crystal is a Peizo electric material, which gives out electricity by applying pressure and vice versa. Learn more about working of Quartz watches on my previous post How a Quartz watch works?. It changes only 15 seconds per month which is pretty much accurate than the precious clocks.

But we need still more accuracy, we depend on time more and more these days, for example the stock market.

For still more accuracy we invented Atomic clocks. Previously a second =1/32,000,000 of an year according to the rotation of the Earth. Scientists felt that, even this is not accurate, the rotation of the earth in its orbit also varies every year due to many factors like moon.

So, to get the most accurate time, the second was defined based on the INTRINSIC property of CESIUM. In these atomic clocks the Cesium is used to tune the waves to a specific frequency. Which has 9,192,631,770 Hz frequency when ever the clock hits that number it counts one SECOND..

For still more accuracy scientists invented Optical clocks which will not show even a second difference for 13 billion years!!!

So let me know your feed back…

“QUARTZ WATCH” How does it work?


The Quartz watches are the most extensively used watches because of their most accurate Timekeeping.

The watch uses a tiny piece of quartz crystal which is the main ingredient of sand “silicon-dioxide” , Quartz crystals are piezoelectric, which means that they generate an electrical charge when mechanical pressure is applied to them. They also vibrate if an electrical charge is applied to them. The frequency of this vibration is a function of the cut and shape of the crystal. Quartz crystals can be cut at a consistent size and shape to vibrate at thousands of times per second(around 32,000Hz), making them extremely stable resonators for keeping very accurate time.

If you have read my previous posts, you might be knowing what exactly “Piezoelectricity” is. If you missed it here’s the link Piezoelectricity.

220px-Inside_QuartzCrystal-Tuningfork
This is how Quartz looks in a watch.

That quartz crystal serves as the oscillator. The battery sends electricity to the quartz crystal through an electronic circuit.  The circuit counts the vibrations and generates regular electric pulses of one per second. Now the motor comes into picture, the electric pulses when reaches the motor, the motor turns the seconds hand and the clock works,

Higher accuracy devices generally use a material with even higher frequencies (again the frequency must be as stable as possible). Atomic clocks count the oscillations between the nucleus and the electrons in an atom (typically cesium) which oscillate at around 9 billion Hz.
