Best Universities In The World : UK Tops League Table.

Best universities in the world: UK tops league table

Oxford snatches top spot in the global rankings – a first for a UK university – but Asia is on the rise

Best universities in the world: UK tops league table

The University of Oxford has become the first UK institution to lead the annual Times Higher Educationrankings, knocking the five-times champion, the California Institute of Technology, into second place.

Oxford topped the list because it has improved across the four main indicators that influence the rankings – teaching, research, citations and international outlook, Times Higher Education said.

Rankings editor Phil Baty welcomed the news but voiced his concern at the consequences of the UK's vote to leave the EU.

"As well as some top academics reporting they have been frozen out of collaborative research projects with EU colleagues, many are admitting that they might look to relocate to a university outside the country," Baty told the BBC.

"The UK must ensure that it limits the damage to academics, students, universities and science during its Brexit negotiations, to ensure that the UK remains one of the world leaders in higher education."

The University of Cambridge and Imperial College London, also feature in the top ten, while University College London (UCL) slipped from 14th place last year to 15th.

Overall, the UK takes 91 of the top 980 places in the 13th annual Times HigherEducation rankings; 88 of these make the top 800 compared with 78 last year.

The list is dominated by US universities. Stanford University is ranked third, the Massachusetts Institute of Technology fifth, Harvard sixth and Princeton seventh. The University of California, Berkeley and the University of Chicago are joint tenth.

More broadly, the rankings show that institutions in Asia have made progress - two new names are now in the top 100 and another four join the top 200.

"The UK will have to watch out for Asia's continuing ascent. Although the notion of Asia as the 'next higher education superpower' has become something of a cliche in recent years, the continent's rise in the rankings is real and growing," says Baty.

How to Block Your Cell Phone Number From Caller ID

How to Block Your Cell Phone Number From Caller ID

It's free and easy; just choose a temporary or permanent block

By Adam Fendelman, Smartphones Expert

While caller ID is a standard way to display incoming phone numbers, you don’t have to let it identify you. Making your mobile number invisible from caller ID is free and easy.

You have two choices with cell phone blocking: you can do a permanent block or a temporary block on a call-by-call basis.

Temporary blocking only works when you call individuals and businesses. Your phone number can’t be blocked when calling toll-free (i.e. 1-800) and emergency services (i.e. 911), due to obvious security reasons.

 Moreover, if you own an Android smartphone or an iPhone, you can hide your caller ID from within the software of your device. 

Here are the simple and free steps for all four choices.

Call-by-Call Block From Caller ID

Just dial *67 before the phone number on your cell phone. This code is the universal command to deactivate caller ID.

For example, placing a blocked call would look like *67 555 555 5555 (without the spaces). On the receiving end, caller ID will usually display “private number” because it has been blocked.

Though you won’t hear or see a confirmation of a successful caller ID block, it will work.

Permanent Block From Caller ID

Just call your cell phone carrier and ask for a line block. This means your phone number won’t appear when you call any number. This is permanent and irreversible. While customer service may attempt to convince you to reconsider, the choice is yours.

Though the code to call your mobile carrier can vary, 611 typically works for cell phone customer service in the United States and Canada.If you temporarily want your number to appear when you have a permanent line block in place, you can dial *82 before the number. For example, allowing your number to appear in this case would look like *82 555 555 5555 (without the spaces).

Do be aware, though, that a minority of people automatically decline calls from phones that block caller ID. In that case, you’d have to allow caller ID in order to make the call.

Hide Your Number On An Android Device

Open Dialer.Press the menu button.Press Additional settings.Enter Caller ID setting.Choose "Hide number" and your number will be hidden.Choose "Show number" or  "Network default" setting to show it back.

Hide Your Number On An iPhone

Go to Settings.Enter 'Phone' setting.Press Show My Caller ID.Use the toggle switch to show or hide your number.

So, there you have it; now you know how to block your caller ID from your recipients.

Nigerians on Twitter have condemned President Muhammadu Buhari for plagiarising the President Barack Obama's 2008 victory speech.

Presidential spokesman, Garba Shehu, had on Friday, September 16, admitted that the paragraph nine of Buhari's speech at the 'Change Begins With Me' campaign launch was a 'copy and paste' of Obama's 2008 speech.

He blamed the reckless insertion on the error of an ambitious staff in the Presidency, saying the matter would be investigated and the offender punished accordingly.

Al though, multiple sources say, the erred staff has been identified and sacked.

Nonetheless, Nigerians have continued to mock the President, describing the incident as embarrassing and hypocritical of the leader demanding 'Change' from his followers.

With the harsh tag #TheStolenSpeech, which is currently trending on the microblogging site Twitter, some said the Presidency did not take responsibility until BBC reported the plagiarism story.

It also emerged that Buhari's popular quote from his 2015 inauguration speech - "I belong to everybody and I belong to nobody" was copied from Charles de Gaulle's 1958 speech.

Charles de Gaulle was a French army officer and statesman. He was the leader of Free France and the head of the Provisional Government of the French Republic.

Airtel New Night plan and Data Offer - Get 500MB for N25, 1.5GB for N50 and Lots More

Airtel New Night plan and Data Offer - Get 500MB for N25, 1.5GB for N50 and Lots More...

By..  Francis Iyamba.

The former Airtel hourly base Night plan has been one of the best data plans which we really enjoyed for unlimited download, but I don't know who gave Airtel bad advised to increase the price of their night plan. Mtn took the advantage and  rescue us with thenight plan of 500MB for just N25, which made lots of people forget the Airtel high price night data bundle and move on with the MTN cheap Night package.

It seems Airtel has learned from their mistake and reintroduced new night data bundle to replace the previous one. Airtel has chosen to follow the footsteps of MTN night packages by launched another Night plan which offers you 500MB for N25 and 1.5GB for N50.

The new Airtel night plan was accompanied by Airtel 1GB for N500 which is valid for 1week and  200MB for N200 + 30Min Airtel calls weekend offer and free 15mb for 7days when you recharge with N200.

To Activate The Offer
This plan is exclusively for SmartTRYBE users on Airtel, it means you must migrate to Airtel SmartTRYBE before you can enjoy the offer, dial *312# then reply with 1

To Subscribe to Airtel 1.5GB for N50, 500MB for N25 and 1GB for N500
» Simply dial *312#
» For 1GB which cost N500, reply with 2 - valid for 7 days
» For 500MB which cost N25 and 1.5GB for N50, reply with 3 - Night Plan from 12am - 5am
» For 200MB which cost N200 + 30Min call, reply with 4 - Weekend: Sat and Sun

Note: The call tariff on SmartTrybe features 11k/s calls charges for all national networks (N6.60K/min)

I can say that this is slightly better than the MTN Night Plan of 500MB for just N25, because with MTN night plan every SIM card entitled to a one-time activation per night, but this Airtel night plan can be renewed if exhausted, it means, you can resubscribe after exhausting the initial 1.5GB. In essence, you can use 3GB for N100 in just one night. When, this is ok, but no amount of capped data can balance with the unlimited data plan, Airtel please bring back our unlimited night plan with the reasonable price.

GALAXY NOTE 7 RECALL: SAMSUNG OWNERS, HERE’S WHAT YOU NEED TO KNOW

GALAXY NOTE 7 RECALL: SAMSUNG OWNERS, HERE’S WHAT YOU NEED TO KNOW

Samsung says battery flaw in production caused excessive heat in Galaxy Note 7

How to prevent a battery fire

How will the news affect Samsung?

Spontaneous combustion is probably the last thing you’d expect from your shiny, expensive new smartphone, but it’s a fate that’s befallen a handful of Samsung Galaxy Note 7 units. Seoul, South Korea-based news agency Yonhap News initially reported that as many as five Note 7 owners have documented their units suddenly catching fire. As of September 2 that number climbed to 35, but reports of explosive phones keep coming, with one allegedly causing a Canadian man’s house to burn down, and another burning asix-year-old in New York.

Unsurprisingly, Samsung spurred to action. The electronics giant halted all shipments of the handset to South Korean mobile carriers in order to “investigate” the issue, and on September 2 took the unprecedented step of recalling the more than 2.5 million Galaxy Note 7 devices that have already shipped to consumers, brick-and-mortar stores, and online retailers since the handset’s launch on August 19.

On September 9, Samsung announced that it had been collaborating with the United States Consumer Product Safety Commission (CPSC) on a plan to “expedite” that recall. In astatement, the agency said, “The CPSC is urging all consumers who own a Samsung Galaxy Note7 to power them down and stop charging or using the device.”

“Samsung continues to ensure that consumer safety remains our top priority,” said Tim Baxter, president of Samsung Electronics America. “Consumers can return their Note 7 for another device.”

The story continues to develop, but here’s what we know so far.

What’s happening?

Initially, the impetus for Samsung’s decision to halt Galaxy Note 7 shipments wasn’t clear.

On August 31, Yonhap News reported that Samsung had temporarily suspended deliveries of Note 7 devices to major South Korean mobile carriers including SK Telecom, KT, and LG Uplus. Initially, the company was reluctant to acknowledge the delay. “We are checking whether the deliveries were halted or not,” a Samsung official told the publication.

Early speculation pointed to a mechanical flaw involving the S-Pen, the proprietary stylus that ships with the Note 7. YouTube videos and reports on the web appeared to show a problem with the S-Pen’s handset slot — the ejection button used to remove the pen had a tendency to become stuck on some units. Samsung acknowledged the issue on Wednesday, began offering free replacements to affected customers, and instructed owners that hadn’t experienced the issue “not to push too hard” in the S-Pen’s housing “after the click sound.”

But evidence of a far more serious — and dangerous — problem began to emerge early this week: the potential for Note 7 devices to explode while connected to a wall charger. One documented account on social media, a YouTube video posted by user Ariel Gonzalez, appeared to show a Note 7 warped almost beyond the point of recognition.

“Came home from work, put it to charge for a little bit before I had class,” he said. “Went to put it on my waist and it caught fire. Yup. Brand new phone, not even two weeks old. Be careful out there, everyone rocking the new Note 7, might catch fire.”

A South Korean schoolteacher, Park Soo-Jung, told the Associated Press that her Galaxy Note 7 “burst into flames” unexpectedly, filling her apartment with smoke. “If the exploded phone in flame was near my head, I would not have been able to write this post.”

And posts on Korean social media appeared to corroborate reports. Most showed Note 7 units with severely damaged screens and charging ports.

In response to the growing chorus of concern, Samsung confirmed to Yonhap News on August 31 that it had delayed Note 7 shipments in order to conduct “quality control” testing. “The most important thing is the safety of our customers, and we don’t want to disappoint our loyal customers,” a company official said.

The results of those tests, the company said, were consistent with reports: some Note 7 units could, under rare conditions, explode while being charged. “[We] conducted a thorough investigation and found a battery cell issue,” it said in a statement on Thursday. “Samsung is committed to producing the highest-quality products and we take every incident report from our valued customers very seriously.”

The company indicated the problem likely wasn’t widespread — Note 7 units with faulty batteries accounted for “less than 0.1 percent of the entire volume sold,” a representative told Yonhap News, or roughly 24 phones for every million sold — but not necessarily easy to resolve. A Samsung representative told Yonhap news that faulty units “couldn’t be [fixed] by changing the battery.”

In its preliminary findings, Samsung says it has discovered a problem in the production process “that placed pressure on plates contained within battery cells,” according to Bloomberg. This pushed the negative and positive poles into contact, which thereby caused excessive heat. An investigation is still underway to sort out the exact cause.

Out of an abundance of caution, then, Samsung announced a broad recall on September 2. “The problem can be simply resolved by changing the battery, but we’ll come up with convincing measures for our customers,” a spokesperson for the company said. “For customers who already have Galaxy Note 7 devices, we will voluntarily replace their current device with a new one over the coming weeks.”

“We acknowledge the inconvenience this may cause in the market but this is to ensure that Samsung continues to deliver the highest-quality products to our customers,” it said. “We are working closely with our partners to ensure the replacement experience is as convenient and efficient as possible.”

If you bought a Note 7, here’s what you should do

You’ll have to send your shiny new Note 7 back where it came from.

Samsung’s Note 7 recall affects almost all of the 2.5 million units that have been shipped to sellers and buyers, and it covers the 10 countries where the phones have been sold. According to the The Wall Street Journal, Samsung has instructed recipients abroad to return Note 7 deliveries as they receive them, and major cell phone carriers in the U.S., Australia, and South Korea have taken the extraordinary step of withdrawing the Note 7 from sale.

Samsung expects that it’ll take “two weeks” to manufacture replacement phones, but said that customers who already bought the phones would get replacements before the new phones go on sale.

It’ll be easy to tell refurbished Note 7 units from the defective models. The Verge reported that Samsung will designate future batches of Note 7 unit with a small, circular sticker affixed to the box bar code. In addition, the company will be launching an online IMEI database tool that will allow owners to quickly determine whether or note their device is safe to use.

What’s a Note 7 owner to do in the meantime, though?

If you’re on a U.S. carrier, you have options:

Sprint announced on Friday that it would offer customers “loaner devices” ahead of the recall.T-Mobile, meanwhile, said it would offer a “complete refund” on Note 7 devices and accessories — specifically, the full amount paid at time of purchase plus any and all associated fees. And it said that it let those who received a free Netflix subscription as a bonus for pre-ordering the Note 7 retain that benefit, if they so choose.Verizon said it would offer refunds and exchanges for Note 7 buyers.AT&T hadn’t announced an exchange process as of publication time, but is expected to later on Friday.

Head into your local carrier stores to obtain refunds or loaner devices. Alternatively, Samsung has started a new exchange program for Note 7 users in the U.S., a program that will come with two different options — either exchange the Note 7 for a new Note 7, or exchange it for a Galaxy S7 or S7 Edge, and you’ll get a refund of the difference in price between the two devices. In addition, every Note 7 owner is getting a $25 gift card from select retailers. To get a new device, you can head to the store you bought the Note 7 from, or call 1-800-SAMSUNG.

Note 7 owners in South Korea, meanwhile, are eligible for a full refund for their device or can exchange it for a new one. And starting Saturday, Samsung said it’ll roll out a “battery-monitoring service” for users in the country to “ensure their devices are safe.”

In the U.K., Samsung has also begun its exchange process, with the company noting that British providers and operators will soon be reaching out to smartphone owners to set up exchanges. If you want to be more proactive, however, you can call Samsung’s customer support team at 0330 7261000 and start the process yourself.

If you’re in Canada, Samsung Electronics Canada Executive Vice President Paul Brannen has made it clear that your safety is a major concern of the company. “Samsung holds safety and consumer satisfaction as a top priority,” he said. “While there have been no confirmed incidents in Canada, Samsung is taking a proactive approach to address customer needs around the Note 7 and immediately addressing any consumer concerns.” Canadian Galaxy Note 7 owners will be able to exchange their phone for either a new version of the same phone, or opt for a Galaxy S7 or Galaxy S7 edge instead. Register your Galaxy Note 7 here for the recall.

There’s one, crucial exception to the recall: China. Samsung said that Note 7 models sold there use a battery from a different supplier that isn’t susceptible to the issue other variants are experiencing.

New Note 7 devices are shipping to customers that replaced them via the recall process beginning the week of September 19. Samsung is distinguishing the fixed devices with a note indicating as such. There will also be a circular sticker with a blue S in the middle that confirms the device’s battery is safe. Samsung says it looks something like this:

On September 13, Samsung is launching a IMEI database tool that lets you run a search to check whether your device is one of the safe replacements. You can check your smartphone’s IMEI number in the settings menu, or check the device’s barcode label on the box.

How long do you have to send it in?

Samsung hasn’t announced a hard-and-fast return window, but said that it would begin exchanging and refunding Galaxy Note 7 devices in South Korea starting September 19.

Verizon customers, meanwhile, have until September 30 to receive a waiver of fees on their Note 7 purchase.

What are the chances your Note 7 will explode?

The Note 7 may be one of the higher-profile consumer devices in recent to exhibit — ahem — explosive tendencies, but it’s far from the first. Still, it seems to be getting the most attention.

Australian airlines, Qantas, Jetstar, and Virgin Australia have banned the charging of Galaxy Note 7’s in the carriers’  cabins. Qantas, in a statement to Reuters, said that is considering a similar ban on in-flight usage. In the U.S., the Federal Aviation Administration (FAA) has advised passengers not to power on or charge Galaxy Note 7 units on domestic flights. And aviation regulators in India and Japan have since followed suit.

The battery’s the problem.

The sort of Lithium-ion cells found in smartphones are packed extremely tightly. As a result, the flammable separator between the battery’s anode and cathode — the two elements between which current flows — is incredibly thin, and therefore prone to damage. Once the separator’s pierced, catastrophe results, typically in the form of a short circuit. An excessive amount of heat boils the battery’s electrolyte, ruptures its cell casing, and causes an explosion or fire.

And worse, Lithium-ion battery fires are difficult to contain. Most electrolytes burn quickly when hit by a fresh supply of air, and when the fire reaches a certain thermal threshold, the materials in the cathode begin to supply oxygen, too.

Samsung will push an over-the-air update to current Note 7 devices in South Korea that limits the battery recharge to 60 percent. That’s to prevent them from overheating and reduce the risk of an explosion, according to the Associated Press. The update will roll out on September 20, but it’s not a solution. Samsung is in talks with carriers to push the update to other Note 7 devices in the U.S. and around the world as an effort to contain the crisis.

In 2006, Dell and Dell were forced to recall millions of laptop batteries after reports emerged of overheating. More recently in 2014, car manufacturer Tesla redesigned its cars to better protect the batteries housed within them.

How to prevent a battery fire

Preventing a battery fire is relatively straightforward and, unless you have a phone prone to exploding like the Note 7, you can usually prevent it by taking these steps. And again, it’s also extremely rare.

Common sense tips to avoid an exploding phone:

Stick to the original charging cable and wall adapter. In the case of the Note 7, use the official Samsung accessories that came bundled with your smartphone.Don’t leave your device in hot areas — especially when it’s charging.If you plan to use a demanding app that’s likely to generate a lot of internal heat, make sure you do so in a well-ventilated, cool place.Don’t smother your smartphone. Putting it under your pillow, or in a tight, restricting enclosure, or under a cushion will encourage a buildup of heat.The same goes for laptops and other devices that use lithium-ion batteries (almost everything that recharges these days).

As for the widely-held perception that fully charged smartphones present a clearer danger than, say, handsets left to drain by your bedside all night, that’s only half true. While battery fires are more intense if the battery is fully charged, the capacity of the battery itself in no way impacts its likelihood of explosion.

How will the news affect Samsung?

The Galaxy Note 7 recall is one of the industry’s largest in history, and obviously a major setback for Samsung. But it’s unclear how drastically it will impact the company’s bottom line — or reputation, for that matter.

Samsung was expected to sell as many as 15 million Note 7 phones this year, or almost double the 9 million Note 5 units it shipped last year. And before this week’s news, it appeared well on its way to hitting that mark: the company said it sold 400,000 units in the first week of the Note 7’s availability and demand had generally outstripped supply.

Samsung’s 2016 revenue had bested expectations, too. The company reported a rise in second quarter operating profit to $15 billion — up 15 percent from the same period a year earlier. And it gained market share at the expense of rivals like Apple, nabbing 22.4 percent of smartphone sales — a five percent jump — thanks to higher-than-anticipated “demand for higher-end phones,” according to market analysts at IDC.

In light of the newest developments, though, some analysts expect a reversal. Park Jung-hoon, an asset fund manager at HDC, told Reuters that that Samsung’s profits would fall short of initial projections. He anticipates a decline in mobile operating profit by up to 200 billion won — or roughly $179 million — in the fiscal period between July and September.

Already, shares of Samsung stock have fallen since the beginning of this week.

SCIENTIFIC  LAWS
# revision purpose

Ampere's Law

Ampere's Law states that, for constant current flow, the flux of electrical current through a surface is proportional to the line integral of the magnetic field (counterclockwise) around its boundary

Archimedes' principle

Archimedes' principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics

Avogadro's Hypothesis

Avogadro's hypothesis states that at the same temperature and pressure, the same volume of any gas will contain the same number of molecules.

Boyle's lawBoyle's law

Boyle's law states that at a constant temperature the volume of a confined ideal gas varies inversely with its pressure.

Brownian motion

Brownian motion is the random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the quick atoms or molecules in the gas or liquid.

Charles's law

Charles's law states If the pressure of a gas remains constant, the volume of the gas will increase as the temperature increases.

Compton effect

Compton effect is a phenomenon in which a collision between a photon and a particle results in an increase in the kinetic energy of the particle and a corresponding increase in the wavelength of the photon

Conservation of energy

The law of conservation of energy stated that energy cannot be created or destroy but it can be transformed from one form to another. This implies that when energy is converted from one form to another, no energy is lost or created during the conversion process.

Coulomb's Law

The interaction between charged objects is a non-contact force that acts over some distance of separation.

Curie's law

In a paramagnetic material the magnetization of the material is (approximately) directly proportional to an applied magnetic field. However, if the material is heated, this proportionality is reduced: for a fixed value of the field, the magnetization is (approximately) inversely proportional to temperature

Dalton's law of partial pressures

Dalton's law (also called Dalton's law of partial pressures) states that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.

Faraday's Law

Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be "induced" in the coil. No matter how the change is produced, the voltage will be generated. The change could be produced by changing the magnetic field strength, moving a magnet toward or away from the coil, moving the coil into or out of the magnetic field, rotating the coil relative to the magnet, etc.

Faraday's First Law Of Electrolysis

The mass of the substance librated or deposited on an electrode during electrolysis is directly proportional to the quantity of electric charge passed through the electrolyte.

Faraday's Second Law Of Electrolysis

If the same quantity of electricity (electric charge) is passed through different electrolytes, the mass of an substance librated or deposited altered at an electrode is directly proportional to their chemical equivalents.

Gauss's law of Electricity

The net number of electric field lines passing through a Gaussian surface is proportional to the total charge enclosed by the Gaussian surface.

Gauss's Law of Magnetism

The net number of magnetic field lines passing through a Gaussian surface is always zero.

Hooke's law

Hooke's law is a principle of physics that states that the force F needed to extend or compress a spring by some distance X is proportional to that distance.

Ideal Gas Law

An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces.

Joule's first law

Joule's first law (Joule heating), a physical law expressing the relationship between the heat generated and current flowing through a conductor.

Joule's second law

Joule's second law states that the internal energy of an ideal gas is independent of its volume and pressure, depending only on its temperature.

Lenz's law

Lenz's law is a common way of understanding how electromagnetic circuits obey Newton's third law and the conservation of energy.

Newton's first laws of motion

The first law states that a body remains at rest or in uniform motion in a straight line unless acted upon by a force.

Newton's second laws of motion

The second law states that a body's rate of change of momentum is proportional to the force causing it.

Newton's third laws of motion

The third law states that when a force acts on a body due to another body, then an equal and opposite force acts simultaneously on that body

Ohm's law

Ohm's law emphasis the principle that the electric current passing through a conductor is directly proportional to the potential difference across it, provided that the temperature remains constant. The constant of proportionality is the resistance of the conductor

Pascal’s principle

Pascal’s principle states that in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container.

Laws of reflection

The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal. The reflected ray and the incident ray are on the opposite sides of the normal.(wikipedia)

Law of Refraction

Law of Refraction stated that When light travels from one medium to another, it generally bends.

Snell's Law

Snell's Law relates the indices of refraction n of the two media to the directions of propagation in terms of the angles to the normal.

Uncertainty principle

Uncertainty principle is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of a particle known as complementary variables, such as position x and momentum p, can be known simultaneously (wikipedia)

Van der Waals force

First law of thermodynamics

The first law establishes a notion of internal energy for a thermodynamic system. Heat and work are forms of energy transfer. The internal energy of a thermodynamic system may change as heat or matter is transferred into or out of the system or work is done on or by the system

Second law of thermodynamics

An isolated physical system, if not already in its own internal state of thermodynamic equilibrium, spontaneously evolves towards it. In an isolated physical system, there is a tendency towards spatial homogeneity.

Third law of thermodynamics

There are various ways of expressing the third law. They derive from the statistical mechanical explanation of thermodynamics. They refer to ideally perfect theoretical models of physical systems.

Know What The Facebook Founder - Mark Elliot Zuckerberg Came to Nigeria For. 

Know What The Facebook Founder - Mark Elliot Zuckerberg Came to Nigeria For. 

The Chairman, Chief Executive Officer, and co-founder of social networking website Facebook - Mark Elliot Zuckerberg visited Nigeria for the first time, arrived on Tuesday afternoon (30th August 2016), touching down in Lagos, Nigeria. He met with local businesses and developers in an effort to understand how Facebook (FB, Tech30) could “better support tech development and entrepreneurship across Africa,” the company said in a statement.

His visit included a trip to a Yaba, known as the Silicon Valley of Nigeria, where he toured a coding camp for kids and met with about 50 local startup founders and developers at CcHub, a local innovation center.

Zuckerberg had traveled to Kenya after visiting Lagos. One day after he left Lagos for Nairobi to “learn about mobile money“, Zuckerberg is back in Nigeria on on Friday 2nd September, 2016 to meet the country’s president Muhammadu Buhari and vice president, Yemi Osinbajo. Zuckerberg has also been attending a start-up demo day hosted by the country’s presidency.

Zuckerberg was in Abuja for the Aso Villa Demo Day which is a program that aims to promote entrepreneurship, innovation and economic growth through new and emerging technology.

Unfortunately, it appears like his plans have suffered an unrecoverable setback on Thursday morning when a SpaceX rocket – owned by Elon Musk exploded during a routine pre-launch check.


Exploded equipment is the Facebook/Spacecom’s AMOS-6 communications satellite, which costs $95 million according to experts estimation.

The Facebook Amos 6 Satellite was scheduled to launch into the orbit on Saturday but now that it's destroyed in the massive blast, it won't be realizable again at least for now.

The Satellite was to provide at about 14 African countries and the Middle East with free/affordable broadband. See what Mark said about the incident;

There are lots of lessons to learn from this an American programmer, Internet entrepreneur, executive, and philanthropist - Mark Elliot Zuckerberg.
His net worth is estimated to be US$53.7 billion as of August 2016, ranking him as the 5th richest person in the world. Source: Wikipedia

Upon all his wealth and personality,
He keeps himself too low
Still works very hard every minute of the day
He appears casual most of the time.
Quietly came to Nigeria (unnoticed)
He trekked in the streets of Lagos without bodyguards and military men
He walked around without sirens
