World’s First Invisible Skyscraper To Be Built In South Korea

The trends of buildings shifted to skyscrapers and since then we have been witnessing more and more stylish skyscrapers rising up to the sky and talking to clouds. However, have you noticed how they block out the view? Yeah, they kind of kill the scenic beauty that we all crave for, don’t they? Today’s article is about how Engineers have come up with a solution for that.

The South Koreans have come up with the idea of buildings by raising a skyscraper that can turn invisible. The idea is to cover the entire building with cameras and LEDs. The LEDs will display whatever the cameras on the other side are looking at.

That means it will be virtually invisible to everybody and hence the skyline will always have clouds and blue skies. That’s wonderful engineering indeed!

Five Important Success lessons to learn from Sachin Tendulkar’s Career

During his 24 exciting years in International cricket, there was hardly anything that Sachin Ramesh Tendulkar did not achieve in the cricket field – fame, recognition, respect, fear in opponents’ heart – he had it all. No doubt why he was always undisputedly referred to as the Bradman of modern cricket. And as far the cricket-crazy Indian populace was concerned, he was the God, the master blaster, and what not! However, the greatness of one of the most beloved son of the soil India has ever produced, is not confined to the cricket field only.

He kissed the final goodbye to all forms of cricket at the Wankhede Stadium, Mumbai couple of days back, thus closing the curtain on a glorious career that started from an an early age of mere 16. As a homage to the batting maestro, we are shedding light into some of the most important success lessons to learn from Sachin’s lengthy cricket career.

1. Be passionate about your goal

This is indeed the most important aspect that you ought to excel in whatever it is that you are pursuing. The reason why Sachin could accomplish so much in cricket because he was always passionate about the game – even after dedicating over two and half decades on it. Being passionate about your goal is always as much important as hard work, which incidentally happens to be the second entry in this list.

2. Hard work

There’s hardly any doubt that Sachin always stood out even amongst the brightest of the cricket players across the world. But have you ever wondered what is it that makes him so special? The answer would obviously be years and years of hard work. Despite all the accomplishment, Sachin never stopped practicing as much hard as he had done in the early years of his career. The bottom line, therefore, is – hard work is the pillar of success no matter which profession you are in. There’s simply no shortcuts whatsoever.

3. Be calm

If you are a keen follower of the game, you must have seen many renowned cricketers snap on or off field for some reason or the other, but Tendulkar was never one of them. Besides his incredible talent, what makes Sachin one of the most respected faces in the world cricket is his quiet and calm nature. This is, in fact, another key ingredient for success.

4. Be humble

Sachin’s humble and down to earth nature is something that adds even more charm not just to his cricketing abilities, but also to his overall persona. The trick here is to never allow your success get into your head.

5. Ability to bounce back hard

Despite all the success, Sachin’s lengthy career also witnessed its own share of misfortunes. In fact, at one point, his career was at the risk of succumbing to injuries. But he never let those down times affect his morale – he kept on trying with full dedication and the rest, as they say, is history. The morale here is – never give up on your goals no matter how tough the challenges thrown at you are.

Why banking is preferred choice for job aspirants in India

 Banking is undoubtedly one of the most preferred choices for job aspirants in India.Every year, tens of thousands of aspirants from across the country apply for openings in banks in both public and private domain.

But, the million dollar question here is – what is it that turn banking into such a lucrative sector for job aspirants? Well, in reality, it’s a combination of a multitude of factors. To help you understand better, we have come up with some of the most prominent reasons why banking has been traditionally one of the most preferred choices for job aspirants at a pan-India level.

1)    Due to their sheer large size and global outreach, banks are exciting to work for. Most of the banks operating in the country provide top-notch working conditions, attractive compensation packages, as well as great learning opportunities.

2)    Banks usually create thousands of employment opportunities every year, and the figure is likely to increase with every passing year. According to various industry estimates, hiring in the sector is going to be over a million in the next 5 years.

3)    Considering the fact that the government is focusing hard on higher rural penetration and financial inclusion, the banking sector indeed comes with huge headroom for growth.

4)    The recruitment drive of banks across the country is not confined to just metro cities. Instead, more and more banks today are recruiting from tier-ii and iii cities, as well as rural areas. This means candidates from both urban and rural areas are provided with equal opportunities when it comes to securing a job in the banking sector.

5)    Both public and private banks use written tests and personal interviews for recruitment. But, unlike in the past, written tests are now held online and candidates are no longer required to travel thousands of miles to another city to appear in these tests.

6)    From the last couple of years, the IBPS has come up with a common written test (CWE) for the recruitment of officers in clerks in 20 public sector/regional rural banks. This essentially means that candidates need to appear in only one written test to make their way through the gateway to 20 banks in the public sector.

7)    Banks are increasingly intensifying their efforts to train and recruit the right candidates. As a result, they are tying up with various universities and learning institutions to get skilled and well trained candidates.

photon

A photon is a fundamental particle of light (does not have any sub-particles). The photon is massless and has no electric charge. In empty space the photon travels at the speed of light. The concept of the photon was developed by Albert Einstein. 

Photoelectric Effect

The photoelectric effect occurs when matter emits electrons upon exposure to electromagnetic radiation, such as photons of light. Here's a closer look at what the photoelectric effect is and how it works.

Overview of the Photoelectric Effect

The photoelectric effect is studied in part because it can be an introduction to wave-particle duality and quantum mechanics.

When a surface is exposed to sufficiently energetic electromagnetic energy, light will be absorbed and electrons will be emitted. The threshold frequency is different for different materials. It is visible light for alkali metals, near-ultraviolet light for other metals, and extreme-ultraviolet radiation for nonmetals. The photoelectric effect occurs with photons having energies from a few electronvolts to over 1 MeV. At the high photon energies comparable to the electron rest energy of 511 keV, Compton scattering may occur pair production may take place at energies over 1.022 MeV.

Einstein proposed that light consisted of quanta, which we call photons. He suggested that the energy in each quantum of light was equal to the frequency multiplied by a constant (Planck's constant) and that a photon with a frequency over a certain threshold would have sufficient energy to eject a single electron, producing the photoelectric effect. It turns out that light does not need to be quantized in order to explain the photoelectric effect, but some textbooks persist in saying that the photoelectric effect demonstrates the particle nature of light.

Einstein's Equations for the Photoelectric Effect

Einstein's interpretation of the photoelectric effect results in equations which are valid for visible and ultraviolet light:

energy of photon = energy needed to remove an electron + kinetic energy of the emitted electron

hν = W + E

where
h is Planck's constant
ν is the frequency of the incident photon
W is the work function, which is the minimum energy required to remove an electron from the surface of a given metal: hν0
E is the maximum kinetic energy of ejected electrons: 1/2 mv2
ν0 is the threshold frequency for the photoelectric effect
m is the rest mass of the ejected electron
v is the speed of the ejected electron

No electron will be emitted if the incident photon's energy is less than the work function.

Applying Einstein's special theory of relativity, the relation between energy (E) and momentum (p) of a particle is

E = [(pc)2 + (mc2)2](1/2)

where m is the rest mass of the particle and c is the velocity of light in a vacuum.

• The rate at which photoelectrons are ejected is directly proportional to the intensity of the incident light, for a given frequency of incident radiation and metal.
• The time between the incidence and emission of a photoelectron is very small, less than 10–9 second.
• For a given metal, there is a minimum frequency of incident radiation below which the photoelectic effect will not occur so no photoelectrons can be emitted (threshold frequency).
• Above the threshold frequency, the maximum kinetic energy of the emitted photoelectron depends on the frequency of the incident radiation but is independent of its intensity.
• If the incident light is linearly polarized then the directional distribution of emitted electrons will peak in the direction of polarization (the direction of the electric field).
