Can we move faster than light!!?

Let’s see it this way, for suppose you are in a train which is moving with the speed of light, and now you want to see your image on a mirror “inside” the train, and as we know, to see our image in a mirror the light must fall on us and then reflect on on to the mirror, only then an image is formed on the mirror.

And as we supposed, we are in a train with the speed of light, so relatively the speed of reflected light and the train is in the same direction and it is zero, so we cannot see our image on the mirror, and this violates the theory of relativity, we must see our image on the mirror. And it is possible when the speed of light in the outside frame of referance is twice the speed of light!!! this is impossible. How can the speed of light from outside is twice?

So to be able to see our image in the mirror, The conclusions of Einstein were, in this case the train should contract in the direction it is moving and the time inside the train should slow down compared to the time outside the train.

So, nothing can move faster than light, at that speed the length becomes zero, time would stop and the mass becomes Infinite.


The only viable way of breaking the light barrier may be through General Relativity and with space time. It looks like moving faster than light but it is actually not moving faster than light.

->The Big Bang itself expanded much faster than the speed of light. But this only means that “nothing can go faster than light”, as we are in the same Universe.

-> If you wave a flashlight across the moon, then, its image can travel faster than light speed (since the beam of light is going from one part of the Universe to another part on the opposite side, which is, in principle, many light years away). Well…. this seems to move faster than light but, it is actually not, it is just travelling faster than light relatively.

“GOOGLE Project SOLI”, Replacing Physical Controls on Smart devices!!!


Google, a giant company, involved in various fields, . This company is pushing the boundaries of innovation. One of such greatest innovations in recent times is “The Project SOLI” which deals with the RADAR finger gestures to interact with our smart devices. Own finger-waving way to control the devices without having to reply on the smartphone. It’s Project Soli replaces the physical controls of smartwatches with your hands using radar to capture your movements.

“CASIO” Smartwatch history

As we know, these days many companies are extremely interested about making wearable tech. The giant company so called “CASIO” joined the battle of smart watches long ago. Casio is showing off its rich history of unusual wristwatches. It’s a pretty amazing collection, with features you never knew existed in digital timepieces. And while many of these can be seen in a new light given the recent rise to prominence of smartwatches, Casio isn’t trying to claim that it was there first.

The Epic moments of CASIO by Verge.

  • The GMW-15, from 1989, had a graphic display to show moon phases and sunrise/sunset times.
  • Here’s a touchscreen watch from 1991, the VDB-1000. It included features like a phone book, organiser, calculator, and notepad.
  • Fitness tracking is one of the most important features in smartwatches today, but Casio’s JC-11 could monitor calories, steps, and distance back in 1991.
  • The BP-400, also released in 1991, was another fitness-focused watch that could monitor blood pressure and heart rate. This model was intended to be more stylish and discreet.
  • Some of Casio’s watches, like the RPS-100W from 1993, were less concerned with subtlety. But if you’d be okay with putting the words “FAT BURNING” on a bright pink watch on your wrist, this could have been for you.
  • 1993’s CPW-100 used a compass to help Muslim wearers face Mecca for daily prayers.
  • Of all the watches Casio is showing off, this one blew my mind the most. The VivCel VCL-100 had an antenna that detected when your phone was ringing, and would vibrate on your wrist as an alert. In 1994.
  • Honestly, one of the most useful things I do with the Apple Watch is use it as an Apple TV remote. These Casio models, however, used infrared to control TVs and VCRs back in 1993.
  • The “thermo-scanner” TSX-1300, from 1994, was able to calculate the surface temperature of an object by detecting its infrared radiation.
  • This UV-700 from 1994 has a UV sensor and skin type meter designed to help you be safe in the sun.
  • This is the ABK-55 from 1995. It’s an analog watch with a raised transparent LCD that shows digital information like phone numbers.
  • These two watches from 1994 and 1995 could play simple multiplayer games over an infrared connection.
  • Here’s one area where Casio has Apple and most Android Wear watches beat — built-in GPS. The PRT-1GP came out in 1999, and was the first watch to come with its own GPS functionality.
  • This DBC-V50 from 1999 has a built-in voice recorder, something I actually really wish my Apple Watch could do.
  • 1999’s HBX-100 had an infrared PC link function to transfer data to and from the watch.
  • The WMP-1 came out in the year 2000, and Casio says it was the world’s first wrist-mounted MP3 player.
  • The WQV series is a trilogy of amazing firsts. 2000’s WQV-1 was the first watch with a digital camera; 2001’s WQV-3 was the first to include a color camera; and the same year saw the WQV-10, which added a color screen.
  • A decade before Apple Pay, 2004’s GWS-900 G-Shock came with a contactless IC chip to make payments via Speedpass. The system was introduced by Mobil in the ‘90s as an easy way to pay for gas at filling stations, and restaurants including McDonalds also experimented with it.
  • 2006’s MGC-10 was developed in collaboration with professional magician Tomohiro Maeda, and includes some close-up magic routines — you can “guess” the number or card someone is thinking of, for example.
  • And here’s where it all started. Casio’s first digital watch, the original Casiotron from 1974.
  • Today, Casio is focused on more traditional watches like this titanium Oceanus model. Although the Oceanus line has been discontinued outside Japan, within Casio’s home country some models in the range sell for up to ¥250,000 (over $2,000) new.

“3D sound” what’s that?

The 3D sound is the most realistic sound created, till this time we were able to here a two dimensional stereo sound which lags in differentiating heights of a sound coming from. Yeah you guessed it, in 3D sound system we are provided with stereos which differentiate height. It is tough to explain but very interesting to experience.

Check out the video below, that’s Awesome. Explanation and Hearing Sound in the third Dimension.

Traditionally, recordings have been made using two methods: mono and stereo. Mono uses a single microphone to pick up sound, while stereo uses two, spaced apart from each other. Binaural recording takes the stereo method one step further by placing two microphones in ear-like cavities on either side of a stand or dummy head. Because the dummy head recreates the density and shape of a human head, these microphones capture and process sound exactly as it would be heard by human ears, preserving interaural cues. The effect is best experienced over headphones, with a clear distinction between left and right perspectives. It’s a simple concept, but when done with high-quality microphones and played over equally high-quality headphones, the effect is eerie: it fools the brain into believing it’s hearing the sounds firsthand.

The illusion creates three-dimensional audio, which is not to be confused with surround sound. Interchanging those terms is the quickest way to amuse — and sometimes annoy — an acoustician. A surround sound system employs multiple speakers to create a 360-degree field around the listener. Say you’re watching a film presented in surround sound: you’ll see an explosion on one side of the screen, and a speaker on the corresponding side of the theater will emit a barrage of sounds. A theater equipped with Dolby Atmos, the company’s most recent iteration of the technology, effectively envelops the audience. But by recreating exactly what your ear hears in any given scenario, binaural audio accomplishes a far more natural 3D sound without a costly speaker.

GOOGLE I/O 2015 Interesting Part.

Google I/O was started in 2008. The “I” and “O” stand for input/output, and “Innovation in the Open”. The format of the event is similar to that of the Google Developer Day.

Google has unleashed a number of tantalizing products and intriguing concepts that have us looking forward it its 2015 conference. Google I/O is an annual developer-focused conference held by Google in San Francisco, California.

 

Google I/O features highly technical, in-depth sessions focused on building web, mobile, and enterprise applications with Google and open web technologies such as Android, Chrome, Chrome OS, Google APIs, Google Web Toolkit, App Engine, and more.

Here comes the most interesting and important part, introduction of super cool hardware and software.

If you wanna watch whole event, check it out.

The world’s roundest object made of sillicon, becomes the new definition of a “KILOGRAM”. Check out the history of “KILOGRAM”.

Check out the video if you have ever used a “kilogram” to measure something.

The “reference kilogram” is a lump of metal in France, the kilo being the only metric measurement not based on some objective standard. A project is underway to replace the kilo with something independently reproducible: perfectly spherical balls of based on Carbon-12. Incidentally, these new kilos would also be “the roundest objects in the world.”

This is brilliant. Fabrication of a Silicon Sphere By definition, an Avogadro number of Carbon-12 atoms weigh exactly 12 grams. As such, the kilogram could be defined as the mass of 1000/12 * Avogadro’s number of Carbon-12 atoms. The Avogadro constant itself is obtained from the ratio of the molar mass to the mass of an atom. For a crystalline structure such as silicon, the atomic volume is obtained from the lattice parameter and the number of atoms per unit cell. The atomic mass is then the product of the volume and density.
