About Marriage




Marriage is like beverage!

Like, enjoying while u drink,
Enjoy the life while u live!!!

Lead the life for Heritage,
Don't treat it as Luggage!!!

Sometimes it will produce High Voltage,
So, don't treat it as Wastage!!!

Sometimes, it will make Cleavage,
At that time, u may need Bandage!!!

Sometimes it will be Average,
Make it to blossom as Flowerage!!!

Don't make it as Garbage!
Run the life without Breakage!!!

Live the life to leave a Footage!
It will give u a new Image!!!

Don't give up, u should Manage!

Maalai Mangum Neram - Rowthiram lyrics

Singer: Ranina Reddy
Lyrics: Thamarai
Music: Prakash Nkki
Song: Maalai Mangum Neram
Movie: ரௌத்திரம்

மாலை மங்கும்  நேரம், ஒரு  மோகம்  கண்ணின்  ஓரம்
உன்னை  பார்த்துக்கொண்டே  நின்றாலும், போதும்  என்று  தோன்றும்
காலை  வந்தால்  என்ன, வெயில்  எட்டி  பார்த்தால்  என்ன
கெடிகாரம்  காட்டும்  நேரம், அதை  நம்ப மாட்டேன்  நானும்

பூங்காற்றும் போர்வை கேட்கும் நேரம் நேரம்
தீயாய் மாறும் தேகம் தேகம்
உன் கைகள் என்னை தொட்டு போடும் கோலம்
வாழ்வின் எல்லை தேடும் தேடும்

மாலை மங்கும்  நேரம், ஒரு  மோகம்  கண்ணின்  ஓரம்
உன்னை  பார்த்துக்கொண்டே  நின்றாலும், போதும்  என்று  தோன்றும்

ஒரு வீட்டில் நாமிருந்து, ஒரிலையில் நம் விருந்து
இருதூக்கம் ஒரு கனவில் மூழ்கி வாழ்கை தொடங்கும்
நான் சமையல் செய்திடுவேன், நீ வந்து அணைத்திடுவாய்
என் பசியும் உன் பசியும் சேர்ந்தே ஒன்றாய் அடங்கும்

நான் கேட்பேன் ஆசை பட்ட பாடல் நூறு,
நீயும் நானும் சேர்ந்தே கேட்போம்,
தாலாட்டை கண்ணில் சொன்ன ஆணும் நீதான்
காலம் நேரம், தாண்டி வாழ்வோம்...

மாலை மங்கும்  நேரம், ஒரு  மோகம்  கண்ணின்  ஓரம்
உன்னை  பார்த்துக்கொண்டே  நின்றாலும், போதும்  என்று  தோன்றும்
..
பால் சிந்தும் பௌர்ணமியில், நாம் நனைவோம் பனி இரவில்
நம் மூச்சுக் காய்ச்சலில், இந்த பணியும் நடுங்கும்
வீடெங்கும் உன் பொருட்கள், அசைந்தாடும் உன் உடைகள்
தனியாக நன் இல்லை என்றே சொல்லி சிணுங்கும்

தீண்டாமல் தீண்டி போகும் வாடை கற்றே
தூக்கம் தீர்ந்து நாட்கள் ஆச்சு.
உன் வாசம் என்னில் பட்டும் வாடி போனேன்,
வாசம் தூன்னாய் நானும் ஆனேன்,

மாலை மங்கும்  நேரம், ஒரு  மோகம்  கண்ணின்  ஓரம்
உன்னை  பார்த்துக்கொண்டே  நின்றாலும், போதும்  என்று  தோன்றும்
காலை  வந்தால்  என்ன, வெயில்  எட்டி  பார்த்தால்  என்ன
கெடிகாரம்  காட்டும்  நேரம், அதை  நம்ப மாட்டேன்  நானும்

How to find Service number for TNEB Online Payment

You can now pay your electricity bills through the Tamilnadu Electricity Bill Payment Gateway. I had some confusion with the service number (aka consumer number) while registering in the portal. I thought I could share with you all how I managed to complete the registration.

The first time you enter the wrong invalid service number, the below error message will be displayed

TNEB Error Invalid Service No / Region
All you need is a little patience and check if you have selected the proper region from the drop-down menu.

TNEB Chennai Region Select Online Bill Payment
The first three characters of the service/consumer number is the section code that denotes your locality. You will find the code for your locality at theWhat is my Region? link at the TNEB Payment Gateway home page (also see useful links below). This will help you correlate the service number written on your white color EB Meter card or printed on previous payment receipts.

TNEB White Meter Card Consumer Number Service Number
Now type in the exact service number in the service no textbox and if it is valid you will get the below message and also the consumer name and address will get auto-populated

Spinors



The concept of spinor is now important in theoretical physics but it is a difficult topic to gain acquaintance with. Spinors were defined by Elie Cartan, the French mathematician, in terms of three dimensional vectors whose components are complex. The vectors which are of interest are the ones such that their dot product with themselves is zero.
Let X=(x1, x2, x3) be an element of the vector space C3. The dot product of X with itself, X·X, is (x1x1+x2x2+x3x3. Note that if x=a+ib then x·x=x2=a2+b2 + i(2ab), rather that a2+b2, which is x times the conjugate of x.
A vector X is said to be isotropic if X·X=0. Isotropic vectors could be said to be orthogonal to themselves, but that terminology causes mental distress.
It can be shown that the set of isotropic vectors in C3 form a two dimensional surface. This two dimensional surface can be parameterized by two coordinates, z0 and z1 where


z0 = [(x1-ix2)/2]1/2
z1 = i[(x1+ix2)/2]1/2.
 

The complex two dimensional vector Z=(z0, z1) Cartan calls a spinor. But a spinor is not just a two dimensional complex vector; it is a representation of an isotropic three dimensional complex vector.

The six myths about Engineering you should know

Two incidents drove me to write this article. In the first incident, a woman wished that her son became a “Mechatronics Engineer” (Mechatronics deals with the mechanical and electronics principles applied together). She explained that “Robotics” is the future of the world (guess Steven Spielberg has had some influence over her) and “Mechatronics Engineers” would be in great demand in future. She thought her son could build a robot on graduating.

In the second incident, a student from my school got into an IIT recently. One of my schoolteachers mentioned this and added: “He is a brilliant student who is well-planned. He has started preparations to sit for GMAT after his engineering.” GMAT is an examination to get into management schools (primarily in the U.S. and several other English-speaking nations). My teacher believes that engineering, followed by a management course, is a good option.

In this article, I try to make clear some facts about ‘engineering' — facts which will prove the above (and some other) expectations and beliefs to be far from reality.
Engineers are super-humans

People do not understand the reality of ‘engineering.' For them, engineers are “super-humans” who build rockets, robots, electric vehicles and the like. The reason is that when a person says he works on a satellite project, people jump to the conclusion that he knows every detail of building a satellite. In reality, no engineer can know the entire details of projects. For example, it requires people from various disciplines such as electrical, mechanical, chemical and materials engineering to design an electric car.

Since the common man has the “super-human” view in mind, he generally does not accept or appreciate many of the “real” engineering works. For example, a home inverter might not bring about any awe to the common man as does an electric vehicle (though both might be equally challenging to build), because he often finds a technician setting right the problems in a home inverter. The technician just knows by experience what to do, whereas an engineer knows why it has to be done.
Engineering is more valuable than science

First, I will clarify the difference between ‘science' and ‘engineering' through a simple example. The study of optics of materials will fall under science. Scientists (physicists, in this case) will try to explain the optical properties which different materials possess. If someone tries to use the optical properties to make a microscope or a camera, he will be an engineer. Scientists establish facts which engineers exploit to make things useful to society. History would tell you that scientists did a lot of engineering work in the earlier days (between 1700 and 1900 when a lot of development really happened in science and engineering).

Today, with the vastness of the different fields, science and engineering have separated . Now, scientists rarely take up engineering work. Nevertheless, I would say scientists play a greater role as they have to establish the basic facts for engineers to build upon.

Unfortunately, since the result of engineering is the one that fetches money, people have a craze for engineering. It is disheartening to see a Ph.D. student in science getting a lesser stipend than a Ph.D. student in engineering. It should have been the other way round. Any nation that ignores the role of science cannot survive in the long run.

Management studies goes with engineering

A degree in engineering followed by a degree in Management is the much sought-after combination. Again, a ‘myth' that engineering and management are related is at work. Engineering (with science as the basis) has nothing to do with management (which does not involve science). A lucrative salary is what attracts people to management studies.

Furthermore, most institutes do not introduce engineering in a proper way, leaving students without confidence to pursue higher education.
We need more IITs

There are many IITs coming up, ostensibly to help the nation meet the requirement of engineers. Truly speaking, we have enough of engineers. Design, the work of engineers, requires just a few people.

The dearth is not in the number but in the quality of engineers we produce. It is enough if we are able to improve and maintain the quality of our institutes and retain the people graduating from them by creating ample opportunities for them to work in India with a good salary. It is better to improve and maintain the standards of the NITs, the IITs and other government institutes than creating newer ones and diluting the existing standards.

Foreign MNCs do best R&D engineering

Foreign multinationals that claim to have research and development centres in India do not do real engineering work in the country, as it is natural for any company to have real product development on home soil.

Here again, the salary is what attracts people (thanks to the dollar-rupee conversion). This is a case of brain drain, in which the brains are hired not to work. Though many might not accept, the basic aim of the foreign MNCs is to utilise the cheap labour in the developing countries to run their manufacturing units; product development is not their primary goal.

People generally end up doing tasks that are not as challenging as is the work in smaller Indian industries trying to develop products of their own.

A B.E/B.Tech graduate is an “Engineer”

With the vastness of technology, in the present day one cannot call oneself an engineer just on graduating. A B.E./B.Tech. graduate knows just the basics. I would say that post-graduation is a must. Or at least, one needs to work for a few years to understand and build engineering products. A lot of people believe that a B.E. graduate in aerospace would be able to build rockets on graduating. If it were so, there would be rockets flying everywhere!

I would advise people without an engineering background to talk to people who do real engineering work to take decisions before choosing the field for their children. The aim of education is not merely to land a high-paying job. It should empower you to find a suitable work for yourself.

Cell Phones' Radiation Report Card

The amount of radiation emitted by cell phones varies from model to model, but all fall under the FCC-mandated maximum absorption rate of 1.6 watts per kilogram of body tissue. Here's a look at some of the highest and lowest emitters


Top 10 Things You Didn't Know About the Moon

Searching for the Lunar Jackpot — Ice

 

 It may not sound like precision science, but researchers are hopeful that plowing a spacecraft into the moon's surface may reveal a hidden layer of frozen water beneath the surface. On Oct. 9, a NASA satellite will hurl a spent rocket into a dark and frigid lunar crater at 5,600 m.p.h.; the impact will equal the force of 1.5 tons of TNT and kick up a massive, six-mile-high plume of dirt and debris. The satellite — the Lunar Crater Observation and Sensing Satellite, or LCROSS — will then photograph and study the plume for evidence of water or ice from colliding comets. After a few minutes of observation, the space vehicle will plunge into the moon's surface as well. Images taken by an Indian satellite earlier this year suggested there was indeed water on the moon; confirming the discovery would be a major boon for scientists who dream of humans inhabiting the moon, Mars and other planets someday.


Was it something we said? While our two celestial bodies remain locked in orbit, the moon is slowly — very slowly — inching away from Earth, at a rate of about 3.8 cm a year. Right now the moon is more than 238,000 miles from Earth, but when it formed, it was just 14,000 miles away.
How do scientists know? The moon's distance is measured by bouncing laser beams off reflectors on the moon's surface that astronauts from the Apollo missions left behind. Scientists can measure the time it takes for the laser beams to travel there and back and calculate the distance with a high degree of accuracy. Eventually, the moon's distance will substantially weaken the oceans' tides and total eclipses of the sun won't be possible for observers on Earth, since the moon will have moved too far away. But that could still take another billion years.



 What was the first sport played on the moon? That would be golf. In 1971, Apollo 14 astronaut Alan Shepard swung a makeshift 6-iron on the moon's surface — and missed the ball. His second swing, however, connected, and the golf ball went flying "miles and miles and miles," as Shepard put it after his swing. In reality, the ball traveled only a few hundred yards — not bad for a 6-iron. That's not Shepard's fault; while the moon's gravity is only one-sixth Earth's, his space suit was so stiff that he could swing the club with only one hand.



Lunar Souvenirs



The astronauts of NASA's Apollo missions collected some 840 lb. of lunar rocks and debris during the 340 hours they spent tooling around on the moon. Since they were brought to Earth, however, the samples have ended up in some unusual places. During the Nixon Administration, nearly 270 moon rocks were presented as gifts to foreign nations. But when a fake turned up in the Netherlands' national museum in September, the Associated Press launched an independent investigation to track the whereabouts of the rest — only to find that many had disappeared. "NASA turned over the samples to the State Department to distribute," one NASA historian told the AP. "We don't have any records about when and to whom the rocks were given." Apollo astronauts were allowed to keep a few rocks as lunar souvenirs, under the condition that they would never be sold but instead passed down from generation to generation. Today, NASA's remaining samples are kept in Teflon bags and stored in nitrogen-filled steel cabinets at the Johnson Space Center in Houston. Any researcher who wishes to handle them must wear three pairs of gloves to prevent contamination.




Slow and Steady Wins the (Space) Race

The first creature to orbit the moon was neither man nor monkey, but a pair of Soviet turtles. The tortoises — along with a passenger list of mealworms, wine flies, seeds and bacteria — were part of a biological payload launched by the Soviet Union in September 1968.
After the Zond 5 spacecraft returned to Earth, the animal comrades were retrieved from the Indian Ocean and found not to have a scratch on them; the shells probably helped. They had, however, lost 10% of their weight, although researchers didn't observe a permanent decrease in appetite.



Seas on the Moon?

 The massive lava plains on the lunar service, dubbed seas by Earth-bound observers, were created by the violent impacts of meteors. Interestingly, most of these lava seas are on the side facing Earth; the force of Earth's gravity pulls the moon's molten interior closer to the surface, making it more susceptible to seeping out during a meteor strike.



Easier Than Peace on Earth

The U.S. joined with the Soviet Union in 1967 to create the Outer Space Treaty, declaring the moon subject to a similar set of rules as those used to govern international waters on Earth. The treaty, which 97 other countries are now party to, makes the moon off-limits for military purposes, keeping countries from ever constructing bases or weaponry on the lunar surface.

Weather in Moon

Talk about extreme weather changes. The moon's surface temperature varies by nearly 500°F, from -240°F when it is dark to 220°F in the sun. And once those extreme temps set in, they stick around for a while — a spot on the moon spends about 13 days in frigid darkness, followed by 13 days in water-boiling sunlight. The lack of atmosphere, which on Earth helps trap heat so it doesn't all dissipate at night, accounts for the wild temperature swings. However, if you dig a meter below the moon's surface, the temperature evens out to a nearly constant -31°F.


The moon doesn't have a dark side, although there's always part of it in the dark — just as there's always a part of Earth that's experiencing night. There is a far side of the moon that we can't see from Earth: because of the way the moon orbits, it always keeps the same side facing us. But the far side is light just as often as it is dark.


Everlasting Footprints


No atmosphere on the moon means no wind or weather — and that, luckily, means no erosion of mankind's historic tracks and prints that still dot the lunar surface. To prove it, NASA's Lunar Reconnaissance Orbiter (LRO) sent back photos in July of the still visible tracks from five of the six Apollo landing sites. While on the moon in 1971, Apollo 14 astronauts Edgar Mitchell and Alan Shepard left behind an Apollo Lunar Surface Experiments Package, or ALSEP, along with sampling equipment and a small cart. The LRO photos were able to clearly show the footpath the astronauts had worn between the two artifacts, and future images are expected to have two to three times the resolution. "The images are fantastic, and so is the focus," says LRO principal investigator Mark Robinson. "It's great to see the hardware on the surface, waiting for us to return."

"Definition of Love" by Swami Vivekananda















I once had a friend who grew to be very close to me. Once when we were sitting at the edge of a swimming pool, she filled the palm of her hand with some water and held it before me, and said this: "You see this water carefully contained on my hand? It symbolizes Love."

This was how I saw it: As long as you keep your hand caringly open and allow it to remain there, it will always be there. However, if you attempt to close your fingers round it and try to possess it, it will spill through the first cracks it finds.This is the greatest mistake that people do when they meet love...they try to possess it, they demand, they expect... and just like the latter spilling out of your hand, love will retrace from you .

For love is meant to be free, you cannot change its nature. If there are people you love, allow them to be free beings.

1. Give and don't expect.

2. Advise, but don't order.

3. Ask, but never demand.

It might sound simple, but it is a lesson that may take a lifetime to truly practice. It is the secret to true love. To truly practice it, you must sincerely feel no expectations from those who you love, and yet an unconditional caring."

Passing thought... Life is not measured by the number of breaths we take; but by the moments that take our breath away....

Tata Motors to introduce Air Car - Is it the next big thing?

 
Tata Motors is taking giant strides and making history for itself. First the Landrover-Jaguar deal, then the world's cheapest car and now it is also set to introduce the car that runs on air, compressed air.



With spiralling fuel prices it is about time we heard some breakthrough!
India's largest automaker Tata Motors is set to start producing the world's first commercial air-powered vehicle.
 
The Air Car, developed by ex-Formula One engineer Guy Nègre for Luxembourg-based MDI, uses compressed air, as opposed to the gas-and-oxygen explosions of internal-combustion models, to push its engine's pistons. Some 6000 zero-emissions Air Cars are scheduled to hit Indian streets by August 2010.  
 
The Air Car, called the MiniCAT could cost around Rs. 3,50,000 ($ 8177) in India and would have a range of around 300 km between refuels.
The cost of a refill would be about Rs. 85 ($ 2).
The MiniCAT which is a simple, light urban car, with a tubular chassis that is glued not welded and a body of fiberglass powered by compressed air. Microcontrollers are used in every device in the car, so one tiny radio transmitter sends instructions to the lights, indicators etc.
There are no keys - just an access card which can be read by the car from your pocket. According to the designers, it costs less than 50 rupees per 100Km (about a tenth that of a petrol car). Its mileage is about double that of the most advanced electric car (200 to 300 km or 10 hours of driving), a factor which makes a perfect choice in cities where the 80% of motorists drive at less than 60Km. The car has a top speed of 105 kmph. Refilling the car will, once the market develops, take place at adapted petrol stations to administer compressed air. In two or three minutes, and at a cost of approximately 100 rupees, the car will be ready to go another 200-300 kilometers. 


As a viable alternative, the car carries a small compressor which can be connected to the mains (220V or 380V) and refill the tank in 3-4 hours. Due to the absence of combustion and, consequently, of residues, changing the oil (1 litre of vegetable oil) is necessary only every 50,000Km).
 
The temperature of the clean air expelled by the exhaust pipe is between 0-15 degrees below zero, which makes it suitable for use by the internal air conditioning system with no need for gases or loss of power.

DO ENDS JUSTIFY THE MEANS?





To answer this question one can look within and, as Nietzsche famously suggested, ask “what does my conscience tell me?” Or such a one can look at the greatest thinkers and their body of work in respect to the philosophical problematic of “means and ends.” In my view, one towering figure stands alone in this regard. And that is Mahatma Gandhi. For Gandhi there were no boundary demarcations between ends and means. Where some dialectical materialists steadfastly cling to the thesis of ends justifying the means, thereby excusing violent methods via which they and their followers sometimes achieve their goals, Gandhi always stood in a moral space diametrically opposed to such a view, never accepting it.

It suffices to say that Gandhi—correctly, I shall argue –believed in a direct moral connection between means and ends. Given the commitment he had to truth and nonviolence and their interdependence, it follows that one ought not employ immoral acts to gain social justice, as these acts will transform one from a moral agent to an immoral agent. In one of his early writings in Young India journal he wrote, “The means may be likened to a seed, the end to a tree; and there is just the same inviolable connection between the means and the end as there is between the seed and the tree.”  

To follow Gandhi’s duty-ethics of truth and nonviolence is to pursue what Rousseau called “civilization.” No civilization can be achieved by violent means. Dropping the atomic bomb on Nagasaki and Hiroshima may have led to an early surrender of Japanese imperial forces (one that many historians argue was inevitable without the bomb), but it destroyed hundreds of thousands of innocent lives and led to the nuclear proliferation, which is a major planetary concern. The means transformed the world in this case into a more violent place where smaller wars in tandem with potential nuclear annihilation are not farfetched realities. To be ethical human beings we must think in holographic ways and see the means as part of any end. In other words, ends do not justify the means. We must commit to the morally correct philosophy of truth and nonviolence if we seek planetary peace.

Few Interesting things about Large Hadron Collider(LHC)

Any way you look at it, the Large Hadron Collider (LHC) is the biggest scientific experiment of all time.

It's essentially an expensive ($10 billion) tunnel that runs for 17 circular miles deep underneath the Franco-Swiss border. Within this tunnel, 10,000 scientists and engineers from almost 100 countries have built a machine that will accelerate two beams of protons in opposite directions, then smash them into each other in the hopes that the results will give them a glimpse of the universe less than a billionth of one second after the Big Bang.

Since September 2008, the LHC -- and by extension, the European Organization for Nuclear Research (CERN) that runs it -- has been in the news for all the wrong reasons, ever since damage from a helium leak delayed the machine's planned launch. There was also that news of a scientist employed by an outside institute to work on the LHC being arrested on suspicion of having ties to al-Qaeda. Allegedly, the man had only progressed to the point of wanting to blow up something; he hadn't actually collected his supplies yet.

The LHC was fired up in November 2009 and on November 23rd, the first proton-proton collision was recorded. On March 30, 2010, the first planned collision occurred creating the highest energy reached by a particle accelerator.

Here are five things you didn't know about the Large Hadron Collider.

1- The Large Hadron Collider is kept colder than outer space

The first thing you didn’t know about the LHC is that it's the world’s largest fridge.

Accelerating charged particles like protons requires a powerful magnetic field, one that can only be produced by using magnets that are first cooled with liquid hydrogen and then supercooled with superfluid helium. Together, this cryogenic distribution system lowers the magnets to an astonishingly cold -456.34F (-271.3C), a temperature slightly colder than that of deep outer space (-454F/-270C). The niobium-titanium cables in the magnets are so cold that they lose all their electrical resistance and become superconducting magnets.

These superconducting magnets create a magnetic field with the force necessary to accelerate the proton beams to 99.9999991% of the speed of light -- the speed at which they collide.

2- The Large Hadron Collider may be trying to sabotage itself

Particle physicists can be divided into two groups: theoretical physicists and experimental physicists. One thinks while the other does, and each figures the other for a chump. Nobel laureate and experimental physicist Leon Lederman once wrote: “If I occasionally neglect to cite a theorist, it’s not because I’ve forgotten, it’s probably because I hate him.”

This disdain is easy to understand after reading the recent work of Holger Nielsen and Masao Ninomiya. As physicists work around the clock to fix the LHC, these two theoretical physicists have offered, as their primary contribution, the following reason for why the LHC is not working: From the moment of the Big Bang, God/nature has hated the fundamental particle researchers hope to create with the LHC -- the so-called Higgs Boson -- with a passion. In fact, it hates it so much that it has sent a Higgs particle into the future in order to kill the machine intent on discovering it.

3- The Large Hadron Collider could win Stephen Hawking his Nobel Prize

For years, celebrated physicist Stephen Hawking has suffered from a severe impediment, one that almost never strikes his peers: Hawking is a best-selling author.

His 1988 book, A Brief History of Time, introduced millions to the basics behind black holes, those astro-toilets with gravitational fields so mighty not even light can avoid the flush. Such unbridled commercial success arrested his credibility in the scientific community the way ALS has paralyzed his body; however, with some luck the LHC could change all that.

In 1974, Hawking published a paper in Nature called "Black Hole Explosions?" predicting that the death of a black hole would produce a burst of thermal radiation (now called Hawking radiation). Should the LHC, as some fear, create a mini black hole (the odds aren't very good) and it dies according to prediction, many agree that it would earn Hawking the Nobel Prize in Physics.

Curiously, Hawking radiation is so widely accepted that scientists at CERN actually used it in a 2003 safety report to dismiss the danger of mini black holes, writing "any microscopic black holes produced at the LHC are expected to decay by Hawking radiation before they reach the detector walls."

4- The Large Hadron Collider contained the hottest spot in the solar system

The superfluid helium within the LHC's superconducting magnets lowers the temperature inside the beam pipes to a chilly -456.34F (-271.3C), but there will be moments within those pipes when the weather changes -- drastically.

Prior to March 2010, officials expected two proton beams to collide 600 million times every second; each collision was expected to create temperatures estimated to be about 100,000 times hotter than the temperature at the core of our sun, which normally runs at around 15,000,000 Kelvin. That equates to a scorching 27 trillion F (1.5 trillion C), so it's fortunate that those moments won't last more than about one trillionth of one second.

5- The Large Hadron Collider relies on Einstein's famous equation

The last thing you didn't know about the LHC is that it won't violate the laws of nature.

Albert Einstein's famous 1905 mass-energy equivalence, E=mc2, revolutionized the way we see the world. Its applications are everywhere including nuclear weapons, in which a mass, such as a lump of Plutonium, is converted into energy. The LHC relies on the same equation, though inverted to m=E/c2 .
