I don't think it should be phased out. Then we would have shortage of mid-level skilled man power in Nigeria. As usual, companies like P&G, Nigeria breweries, Mobil e.t.c would then need to bring philipinos, chinese e.t.c for technical jobs that an ond or hnd grad would have easily been able to do.
There are also still people out there that prefers hands-on learning to theoretical learning. The solution is that people should go for what interests them, and not thinking of hnd as a 2nd option after failing uni jamb.

I can't imagine a country like Canada surviving without their polytechnics and colleges.

poly"technics" - Technical college (Hands on learning)
Universities - Theoretical (research and analysis)

Honestly, I would nt want the HND program to be phased out, middle-level skill wil die if dat happens. I said its being phased out because the federal government has no plans for dem. Does FG consider polytechnics in its scheme of tins?
Third world countries lik Nigeria shud always encourage polytechnics because of d practical knowledge they bring.
Infact the practical knowledge I offer in my place of work was acquired from polytechnic.
I went to Universirty to just prove a point nd am happy I got it.

I am a proud holder of both BSc nd HND.
There s no denial in the profound discrimination btw the two certificates.
I will advice if anybody has the chance to go for BSc tru JAMB or tru DE immediately after OND, such a person shud nt hesitate to do so.
HND is being phased out.

How do someone PM on nairaland?

Desperado! Do u wanna contact him for marriage?
D problem wit ds online dating, remember u will meet him one of u won't lik the other.
Online dating my foot

Do tell me at what salary range would be ideal to get married and tell me if at this rate we will ever achieve that rise.

Fela once sang about the worker trying to buy fan. This guy saves everything he can afford to buy a fan at 50 naira then. When he was almost meeting his target, price of fan skyrocketed and the cycle goes on and on.

At no time will it be adequate until u take the bull by the horn and get married on the level you're o

U r absolutely corect. No time or amount s adequate nd none s inadequate. Wat matters is finding the rite person, hw many ladies r ready to manage? Hw many r ready to live in kind of apartment wit d man? Some ladies r carriers of favor likewise some men.

With 18k I will help manage the home by taking drastic measures such as the following

1. No Internet Data
2. No DSTV
3. No weave-on
4. No make-ups
5. No spending on friviolities
6. Look for the cheapest market and buy food stuff en bulk
7. Setup a backyard garden to cater for some food stuff needs.
8. Get involved in church activities
9. Thrown shame away to the bin and embrace free distributions from churches and NGOs

I swear from the 18k and all the above, I will save at least 1k or more per month.

What takes most of our income is largely because we spend more on friviolities than essentials. Our parents were not millionaires when they got married naa

On the present economic condition it wil b difficult, 50K earners wil find it difficult to get married nt to talk of those on 18K.
Bt on a commendable note, if wat u just said its from ur hrt I must say dat u r a rare specie among ladies, a gud manager of resources nd a dream lady for any man. Thumps up!

Wat makes u tink dat all working class ladies will make better wives? I ve seen dem all- the working class lady nd d students.
Wat makes a gud wife is maturity, understanding nd luv. Do u knw dat most working class ladies r pompous, they just feel ontop of d world nd in most times place high expectation on their would-be husbands. She has the tendency to compare their husbands wit some rich colleagues. While some gud female students can manage nd accept d man d way he is.
Evrytin boils down to understanding nd love.
If u say its gud to marry working lady, r u saying that d essence of getting married is economy? Just financial security? Wat if d lady looses her job 2morow?
Love nd compartibility r the key to getting married to whosoever.

Lemme add,
Its advisable to buy laptop dat has 64bit dan d one wit 32bit. D ram of a 64bit s upgradable to 128Gig while d maximum ram a 32bit laptop wil ve s 4Gig.
Also the higher d clock speed (Ghz) d faster d laptop.
Nice one @OP

10) He is not romantic nd caring I can't marry him.
Most times ladies expect a 30yr old to behave lik a 22 year old all in d name of romance. because d guy. Does not pierce his nose nd ears in order to look lik a gangster then d nxt tin u wil s dat d guy s old fashioned.

Quite a difficult time its for u nw. I knw u feel, so sad nd full of regret. One thing is sure, u can't turn back d hands of time but u can certainly learn from this mistake. D deed is done bt great lessons infact everlasting lessons to learn.
If u can discuss it wit ur mum, look for any of ur mum's sis (ur aunt), d one dat ur mum wil listen to u nd tell dem wat happened. This is in a bid to avoid terminating d baby.
Abortion s no gud,
Am sure @ 21 u r stil in skul, @ 21 I had nt tasted sex, because I concentrated in my studies.

I don't beliv ds story. Lai has always been telling lies. Y can't he mention the names of d dismmised officials or the name of d parastatal.
Telling lies d world.

She s cul, real cute.

Its simple, all u need is calmness of mind a lil practice in ur room. Gudluck son

Seems u ve been treated for madness b4

Quite funny! Bt these r dsame ppl u see in all d newspaper stand in Nigeria.

Hmmm. ..... coming up soon by NL physicist..... earth shaking inventions!.... a bomb?

Earth-shattering bomb!

Randyhot:
Most nigerian ladies live in fantasies, that's why they will always end up heartbroken, their expectations in a man always read like the canticles of solomon in the book of songs.

U r correct! Dats y most of dem r nt real.

Ur fellow what? Come mr. Man' don't provoke me oh.... Wat have u been able to develop? Even the malaria drugs u sell u still make mistakes.

Last time i check almost all the hospital in my area close up when they hear
ebola.

My guy! We r doing well. I nd my team of great minds r coming up wit our earth-shaking inventions. Just keep arms crossed.

Very encouraging! Keep it my fellow Physicist! Given a conducive environment we can do more. Bravo!

Wats nt clear to me is how Oloshos, more oloshos, whores, call girls, red light street girls keep on making headlines esppecially on nairaland.
I just don't understand it. Now I knw y we ve so much retardation in intellectual reasoning, d young ones, d youths atimes look up these oloshos as role model wen ds oloshos ve noting meaningful to offer.
Pitiable country!

Gee! U no tell us hw much u collected.

Though I can't read meaning into ds pix bt d truth is Ngozi Okonjo is a great economist, she has d stuff bt greed nd corruption dd nt allow her to perform.
I have faith in Ngozi dan in Kemi in terms of better economic policies.
Under normal circumstances, Kemi is supposed to be a junior minister for the economy.
She needs time to mature sha.
Don't get me wrong, I voted for APC in d last election.

Nwaobodo! In as much as we r from dsame state I don't beliv u. U r lying. 1st of all bring out d Money Donatus Dasuki gave u, submit it to d federal government b4 we can admit u into APC.
U r joining APC in order to avoid being investigated abi?
Y dd nt u public voice out ur disapproval of PDP workings then?
U wan chop wia u no sow?

Relativity is one of the most famous scientific theories of the 20th century, but how well does it explain the things we see in our daily lives?
Formulated by Albert Einstein in 1905, the theory of relativity is the notion that the laws of physics are the same everywhere. The theory explains the behavior of objects in space and time, and it can be used to predict everything from the existence of black holes, to light bending due to gravity, to the behavior of the planet Mercury in its orbit.
The theory is deceptively simple. First, there is no "absolute" frame of reference. Every time you measure an object's velocity, or its momentum, or how it experiences time, it's always in relation to something else. Second, the speed of light is the same no matter who measures it or how fast the person measuring it is going. Third, nothing can go faster than light.
The implications of Einstein's most famous theory are profound. If the speed of light is always the same, it means that an astronaut going very fast relative to the Earth will measure the seconds ticking by slower than an Earthbound observer will — time essentially slows down for the astronaut, a phenomenon called time dilation.
Any object in a big gravity field is accelerating, so it will also experience time dilation. Meanwhile, the astronaut's spaceship will experience length contraction, which means that if you took a picture of the spacecraft as it flew by, it would look as though it were "squished" in the direction of motion. To the astronaut on board, however, all would seem normal. In addition, the mass of the spaceship would appear to increase from the point of view of people on Earth.
But you don't necessarily need a spaceship zooming at near the speed of light to see relativistic effects. In fact, there are several instances of relativity that we can see in our daily lives, and even technologies we use today that demonstrate that Einstein was right. Here are some ways we see relativity in action.
1. Global Positioning System
In order for your car's GPS navigation to function as accurately as it does, satellites have to take relativistic effects into account. This is because even though satellites aren't moving at anything close to the speed of light, they are still going pretty fast. The satellites are also sending signals to ground stations on Earth. These stations (and the GPS unit in your car) are all experiencing higher accelerations due to gravity than the satellites in orbit.
To get that pinpoint accuracy, the satellites use clocks that are accurate to a few billionths of a second (nanoseconds). Since each satellite is 12,600 miles (20,300 kilometers) above Earth and moves at about 6,000 miles per hour (10,000 km/h), there's a relativistic time dilation that tacks on about 4 microseconds each day. Add in the effects of gravity and the figure goes up to about 7 microseconds. That's 7,000 nanoseconds.
The difference is very real: if no relativistic effects were accounted for, a GPS unit that tells you it's a half mile (0.8 km) to the next gas station would be 5 miles (8 km) off after only one day.
2. Electromagnets
Magnetism is a relativistic effect, and if you use electricity you can thank relativity for the fact that generators work at all.
If you take a loop of wire and move it through a magnetic field, you generate an electric current. The charged particles in the wire are affected by the changing magnetic field, which forces some of them to move and creates the current.
But now, picture the wire at rest and imagine the magnet is moving. In this case, the charged particles in the wire (the electrons and protons) aren't moving anymore, so the magnetic field shouldn't be affecting them. But it does, and a current still flows. This shows that there is no privileged frame of reference.
Thomas Moore, a professor of physics at Pomona College in Claremont, California, uses the principle of relativity to demonstrate why Faraday's Law, which states that a changing magnetic field creates an electric current, is true.
"Since this is the core principle behind transformers and electric generators, anyone who uses electricity is experiencing the effects of relativity," Moore said.
Electromagnets work via relativity as well. When a direct current (DC) of electric charge flows through a wire, electrons are drifting through the material. Ordinarily the wire would seem electrically neutral, with no net positive or negative charge. That's a consequence of having about the same number of protons (positive charges) and electrons (negative charges). But, if you put another wire next to it with a DC current, the wires attract or repel each other, depending on which direction the current is moving.
Assuming the currents are moving in the same direction, the electrons in the first wire see the electrons in the second wire as motionless. (This assumes the currents are about the same strength). Meanwhile, from the electrons' perspective, the protons in both wires look like they are moving. Because of the relativistic length contraction, they appear to be more closely spaced, so there's more positive charge per length of wire than negative charge. Since like charges repel, the two wires also repel.
Currents in the opposite directions result in attraction, because from the first wire's point of view, the electrons in the other wire are more crowded together, creating a net negative charge. Meanwhile, the protons in the first wire are creating a net positive charge, and opposite charges attract.
3. Gold's Yellow Color
Most metals are shiny because the electrons in the atoms jump from different energy levels, or "orbitals." Some photons that hit the metal get absorbed and re-emitted, though at a longer wavelength. Most visible light, though, just gets reflected.
Gold is a heavy atom, so the inner electrons are moving fast enough that the relativistic mass increase is significant, as well as the length contraction. As a result, the electrons are spinning around the nucleus in shorter paths, with more momentum. Electrons in the inner orbitals carry energy that is closer to the energy of outer electrons, and the wavelengths that get absorbed and reflected are longer. [Sinister Sparkle Gallery: 13 Mysterious & Cursed Gemstones]
Longer wavelengths of light mean that some of the visible light that would usually just be reflected gets absorbed, and that light is in the blue end of the spectrum. White light is a mix of all the colors of the rainbow, but in gold's case, when light gets absorbed and re-emitted the wavelengths are usually longer. That means the mix of light waves we see tends to have less blue and violet in it. This makes gold appear yellowish in color since yellow, orange and red light is a longer wavelength than blue.
4. Gold Doesn't Corrode Easily
The relativistic effect on gold's electrons is also one reason that the metal doesn't corrode or react with anything else easily.
Gold has only one electron in its outer shell, but it still is not as reactive as calcium or lithium. Instead, the electrons in gold, being "heavier" than they should be, are all held closer to the atomic nucleus. This means that the outermost electron isn't likely to be in a place where it can react with anything at all — it's just as likely to be among its fellow electrons that are close to the nucleus.
5. Mercury Is a Liquid
Similar to gold, mercury is also a heavy atom, with electrons held close to the nucleus because of their speed and consequent mass increase. With mercury, the bonds between its atoms are weak, so mercury melts at lower temperatures and is typically a liquid when we see it.

6. Your Old TV
Just a few years ago most televisions and monitors had cathode ray tube screens. Acathode ray tube works by firing electrons at a phosphor surface with a big magnet. Each electron makes a lighted pixel when it hits the back of the screen. The electrons fired out to make the picture move at up to 30 percent the speed of light. Relativistic effects are noticeable, and when manufacturers shaped the magnets, they had to take those effects into account.
7. Light
If Isaac Newton had been right in assuming that there is an absolute rest frame, we would have to come up with a different explanation for light, because it wouldn't happen at all.
"Not only would magnetism not exist but light would also not exist, because relativity requires that changes in an electromagnetic field move at a finite speed instead of instantaneously," Moore, of Pomona College, said. "If relativity did not enforce this requirement … changes in electric fields would be communicated instantaneously … instead of through electromagnetic waves, and both magnetism and light would be unnecessary."
8. Nuclear Plants and Supernovas
Relativity is one reason that mass and energy can be converted into each other, which is how nuclear power plants work, and why the sun shines. Another important effect is in supernova explosions, which signal the death of massive stars.
"[Supernovas] exist because relativistic effects overcome quantum effects in the core of a sufficiently massive star, allowing it to suddenly collapse under its own weight until it becomes a much smaller and harder neutron star," Moore said.
In a supernova, the outer layers of a star collapse down onto the core, and create a gigantic explosion that, among other things, creates elements heavier than iron. In fact, nearly all the heavy elements we are familiar with are made in supernovas.
"We are made of stuff created in and dispersed by [supernovas]," Moore said. "If relativity did not exist, even the most massive stars would end their lives as white dwarfs, never exploding, and we would not be around to think about it."
