On the other hand, Nigeria has a huge population, very adventurous and wealthier people than Ghana: this means more Nigerians are able to travel to Dubai than people from other African nations. When Nigerians are not travelling legally (relatively affluent), they’ll do so adventurously (relatively poor). Visa restrictions control potentially large (overall numbers) trooping over there legally. Nigerians should be angrier if Indian and Chinese nationals are less restricted than Nigerians. This is the better test of Nigeria’s standing and basses for questioning polices that affect Nigerians in the current instance.


Forget what the Western world does with Ghana or the Western world will use Ghana more as a means of disguising their racist policies towards Nigerians. Nigeria is the more significant black nation.

British Athletics will look into Adam Gemili and Daryll Neita's American-based training group after one of their training partners was prevented from competing at the Olympics due to a failed drugs test.

Nigerian sprinter Blessing Okagbare was expected to challenge for medals in the 100 metres and 200m in Tokyo, but was provisionally suspended for human growth hormone 12 hours after winning her 100m heat. She took no further part in the Olympics.

Okagbare is coached by former British Athletics employee Rana Reider in Florida, with Gemili and Neita also part of the group, alongside Canada's Olympic 200m champion Andre De Grasse.

Neita made a huge breakthrough at the Olympics, becoming only the second British woman to break 11 seconds on her way to making the 100m final. Gemili pulled up injured during his 200m heat.

British Athletics will speak to its standards, ethics and rules committee to seek procedural advice over what, if anything, it should do to proceed. It is understood no investigation has been launched. Gemili and Neita are not accused of any wrongdoing.

Okagbare's drugs sample was collected in an out-of-competition test on July 19, but the laboratory that analysed it only informed the Athletics Integrity Unit of the positive result after Okagbare’s first-round triumph in Tokyo.

A regular in global sprint finals, she ran the second-fastest 100m time in all conditions in June when clocking 10.63 seconds in Lagos. The time did not count as legal due to the 2.7m/s tailwind.

Although they finished with six medals, these Olympics marked the first time Britain did not win an athletics gold since 1996. Christian Malcolm, British Athletics Olympic head coach, said he would conduct a thorough review after the event.

"We identify there is some good talent coming at the moment," he said. "How do we support it? Where are the gaps? What do they need? What's their plan over the next two, three years to get them to where they need to get to?

"We've got to be able to have those conversations and those reviews, look forward and be strong in support for them.

The great thing about it is we've shown we have some real athletes with real pedigree for the future. We've got three big championships next year, followed by the worlds and back into the Olympic Games. So, it's a short turnaround.

"Some of our young talent is coming through and some is at home after just missing out here. We just have to try and support them in the right way."

There's obviously something Ghana is doing rightly that Nigeria isn't getting right.

That's the first thing Nigeria needs to unravel.

Whites or the none black races want Nigerians to behave like Ghanaians and not like human beings. Steven was not a man, Django was. If in reality, slaves in every plantation would hate Django. Today, the imagined ownership of blacks persist

As for Nigeria, Nigeria does not leverage her clout on the world stage and we are taken for granted. like I keep saying, Nigeria gains nothing from UAE, UAE gains much from Nigeria.

In brief Neural networks can correctly guess a person’s race just by looking at their bodily x-rays and researchers have no idea how it can tell.

There are biological features that can give clues to a person’s ethnicity, like the colour of their eyes or skin. But beneath all that, it’s difficult for humans to tell. That’s not the case for AI algorithms, according to a study that’s not yet been peer reviewed.

A team of researchers trained five different models on x-rays of different parts of the body, including chest and hands and then labelled each image according to the patient’s race. The machine learning systems were then tested on how well they could predict someone’s race given just their medical scans.

They were surprisingly accurate. The worst performing was able to predict the right answer 80 per cent of the time, and the best was able to do this 99 per cent, according to the paper.

"We demonstrate that medical AI systems can easily learn to recognise racial identity in medical images, and that this capability is extremely difficult to isolate or mitigate," the team warns [PDF].

"We strongly recommend that all developers, regulators, and users who are involved with medical image analysis consider the use of deep learning models with extreme caution. In the setting of x-ray and CT imaging data, patient racial identity is readily learnable from the image data alone, generalises to new settings, and may provide a direct mechanism to perpetuate or even worsen the racial disparities that exist in current medical practice."

Mind-blowing discovery: Google creates a time crystal


Quantum time crystals are no less than a new 'phase of matter,' which has been theorized for some years.

A group of scientists in partnership with Google’s quantum computing labs say they have created the world’s first 'Time Crystal' inside a quantum computer. Credit: Handout.
If you had a Starbucks coffee today, you might have asked for some milk or cream.

The latter will eventually dissolve throughout the coffee, instead of sitting on the top, enabling the overall system to come to an equilibrium.

This irresistible drive towards thermal equilibrium, as described in the second law of thermodynamics, is reflective of the fact that all things tend to move towards less useful, random states.

As time goes on, systems inevitably degenerate into chaos and disorder — that is, entropy.

Kind of like life. It starts out great, then it all goes to hell

But what if something were to come along, that would turn all of that, on its head? What if the milk or cream didn’t mix. What if it just sat at the top?

According to a report at ZDNet.com, in a new research paper, Google scientists claim to have used a quantum processor for a useful scientific application: to observe a genuine time crystal.

If “time crystal” sounds pretty sci-fi that’s because they are.

Time crystals are no less than a new “phase of matter,” as researchers put it, which has been theorized for some years now as a new state that could potentially join the ranks of solids, liquids, gases, crystals and so on.

As you can imagine, time crystals are elusive … they are not standing on a street corner, waiting to be found.
But Google’s scientists now claim that their results establish a “scalable approach” to study time crystals on current quantum processors, ZDNet.com reported.

Understanding why time crystals are interesting requires a little bit of background in physics – particularly, knowledge of the second law of thermodynamics, which states that systems naturally tend to settle in a state known as “maximum entropy.”

Let’s go back to your coffee cup.

Time crystals, scientists say, fail to settle in thermal equilibrium.

Instead of slowly degenerating towards randomness, they get stuck in two high-energy configurations that they switch between — and this back-and-forth process can go on forever.

To explain this better, ZDNet.com talked to Curt von Keyserlingk, lecturer at the school of physics and astronomy at the University of Birmingham, who did not participate in Google’s latest experiment.

It starts with a thought experiment: take a box in a closed system that is isolated from the rest of the universe, load it with a couple of dozens of coins and shake it a million times.

As the coins flip, tumble and bounce off each other, they randomly move positions and increasingly become more chaotic, says von Keyserlingk.

Upon opening the box, the expectation is that you will be faced with roughly half the coins on their heads side, and half on their tails.

It doesn’t matter if the experiment started with more coins on their tails or more coins on their heads: the system forgets what the initial configuration was, and it becomes increasingly random and chaotic as it is shaken.

Enter Google’s quantum processor, Sycamore, which is well known for its achievements and is now looking for some kind of useful application for quantum computing, ZDNet.com reported.

A quantum processor, by definition, is a perfect tool to replicate a quantum mechanical system, says von Keyserlingk.

In this scenario, Google’s team represented the coins in the box with qubits (units of quantum information) spinning upwards and downwards in a closed system; and instead of shaking the box, they applied a set of specific quantum operations that can change the state of the qubits, which they repeated many times.

This is where time crystals defy all expectations.

Looking at the system after a certain number of operations, or shakes, reveals a configuration of qubits that is not random, but instead looks rather similar to the original set up.

“The first ingredient that makes up a time crystal is that it remembers what it was doing initially. It doesn’t forget,” says von Keyserlingk. “The coins-in-a-box system forgets, but a time crystal system doesn’t.”

The weirdness doesn’t stop here.

Shake the system an even number of times, and you’ll get a similar configuration to the original one – but shake it an odd number of times, and you’ll get another set up, in which tails have been flipped to heads and vice-versa.

Scientists call this a break in the symmetry of time – which is why time crystals are called so, ZDNet.com reported.

Unlike the coins in the box, which get all muddled up and settle at roughly half heads and half tails, they buck the entropy law by getting stuck in a special, time-crystal state.

Newton’s second law of thermodynamics says that this simply can’t happen, but time crystals don’t seem to give a hoot about entropy.

Ponder that one for a moment.

Time crystals have been a topic of interest since 2012, when Nobel Prize-winning MIT professor Frank Wilczek started thinking about them; and the theory has been refuted, debated and contradicted many times.

Only last month, a team from Delft University of Technology in the Netherlands published a pre-print showing that they had built a time crystal in a diamond processor, although a smaller system than the one claimed by Google.

There are, of course, some caveats.

Like all quantum computers, Google’s processor still suffers from decoherence, which can cause a decay in the qubits’ quantum states.

And one thing is certain: time crystals won’t be sitting in our living rooms any time soon, as scientists have yet to find a definitive useful application for them.

That said, if what Google’s quantum computer accomplished can be replicated, then time crystals aren’t just real, but they might actually be put to some actual real world use.

The implications of such a technology for computer memory alone are hard to fathom, much less for computer processing itself.

The paper remains in pre-print and still requires peer review.

The most wicked? Boy, you must have one very peculiar way of seeing the world, possibly caused by ignorance of history, inability to draw upon what you've learned in the past or you're white. Whites are blind to thire faults.

Poor list.

1. Must be a good Nigerian leader

Meaningless: There’s no God to consult on what a good leader is; subsequently, the decision is left to us humans to decide. Unfortunately this means one mans bad leader is another mans good leader. Up north Buhari is looked on as a good leader. Besides, in novel writing this is known as Telling and not Showing. You shouldn’t write that someone was a good leader or was evil, you need to show how they are a good leader or evil.

2. Must be a person who is well travelled across Nigeria

Not great for this could mean someone who travels across Nigeria for the purposes of willing and dealing over political power and paying homage to god-fathers by kneeling and kissing one their many ringed knuckles.

3. Must be someone who has friends everywhere

Friend everywhere in the Nigeria context does not suggest someone gregarious, affable and enlightened but someone positioning to milk the nation dry by conniving with persons in positions of power such as business moguls, heads of ports authority, oil industry, police chives, and sundry influencers.

4. Must be very verse in Economics

Not very imaginative since this would be on everyone’s list.

5. Must be a good Politician

See reason why number 1 on the list is meaningless.

6. Should be able to ‘talk’ to Nigerians

Eh, the worst point of all. Firstly Nigerians talk in over 400 languages from Igbo, Hauser, Isoko, Efik to Rubbish. Youths are the worst, beguiled, as they often are, by everything “the West”. Some would happily plunge Nigeria into civil war for trivial issues such as love for Twitter.

Excellent, diversity is good for the economy, good for exposing underexposed Nigerian minds to verity, dragging them screaming from the shadows of primitivity where sinister folks abroad easily exploit and brainwash them into separatism. There’s more to life than cussing, lying and killing. I guess unless the churches and Mosques get involved in starting their own forms of lottery, opposition may arises from this constituent in the form of eschewing the veracity of gambling.

To take an example: if you pour some milk into a coffee cup, the milk will eventually dissolve throughout the coffee, instead of sitting on the top, enabling the overall system to come to an equilibrium. This is because there are many more ways for the coffee to randomly spread throughout the coffee than there are for it to sit, in a more orderly fashion, at the top of the cup.

This irresistible drive towards thermal equilibrium, as described in the second law of thermodynamics, is reflective of the fact that all things tend to move towards less useful, random states. As time goes on, systems inevitably degenerate into chaos and disorder – that is, entropy

Time crystals, on the other hand, fail to settle in thermal equilibrium. Instead of slowly degenerating towards randomness, they get stuck in two high-energy configurations that they switch between – and this back-and-forth process can go on forever.

To explain this better, Curt von Keyserlingk, lecturer at the school of physics and astronomy at the University of Birmingham, who did not participate in Google's latest experiment, pulls out some slides from an introductory talk to prospective undergraduate students. "They usually pretend to understand, so it might be useful," von Keyserlingk warns ZDNet.

It starts with a thought experiment: take a box in a closed system that is isolated from the rest of the universe, load it with a couple of dozens of coins and shake it a million times. As the coins flip, tumble and bounce off each other, they randomly move positions and increasingly become more chaotic.

It doesn't matter if the experiment started with more coins on their tails or more coins on their heads: the system forgets what the initial configuration was, and it becomes increasingly random and chaotic as it is shaken.

This closed system, when it is translated into the quantum domain, is the perfect setting to try and find time crystals, and the only one known to date. "The only stable time crystals that we've envisioned in closed systems are quantum mechanical," says von Keyserlingk.

GabrielYulaw:
It's Yulaw not Yaw. I no be Seyi Law.

Positives? I guess the biggest positive is that there's something incomprehensible binding us all together that has so far resisted what would have split other countries into pieces. That something defies belief and comprehension and I don't know if it can hold forever. But I do hope so because the primary problem with Nigeria is not Nigeria but Nigerians and we are stronger together than apart.

Well in my view it's unsurprising, nothing incomprehensible, Nigeria remains one since Nigerians do not posses significant ethic hatred of one another or cross tribes. I doubt that even leaders do, they affect it. At a minimum, wealth and affluence elevates them above such hatreds even against will at an intrinsic level. They create ethnic division for the selfish purpose of political leverage and power from its foundational group identity.

Increase of tribal rhetoric on Nairaland and all social media is not evidence of tribal hatred among Nigerians but evidence to the contrary, which is why I believe it is about concerted effort to create that missing ethnic hatred. We knew our differences but we are now being made to be aware of them.

For Those NIGERIAN LADIES who may be struggling to reconcile with her points;
Here are her POINTS, highlighted easily;
1. Post partum Belle but never pregnant.
2. Never contributes financially, emotionally.
3. Dirty punnany.
4. 250% Density wig wearing

Finally, what does an average Nigerian Lady have to offer beyond punnany?
This is exactly what we have been saying since.
I weep on their behalf

Lol, no females have no 3 more than white women. And, unlike how Nigerians are taught from birth, they don’t even immediately wash after doing a number 2.

Why people cast aspersions at Nigerian women that are the cleanest in this aspect than possibly any race of women in the world is baffling outside of White racists assumptions about black women generally.

GabrielYulaw:
I don't hate the country. I'm just disgusted, angry and disappointed with the way things are. Nigeria could be so much better than it is and it pains me that we are where we are at the moment with no visible hope that things go be better anytime soon and that we go take our rightful place in the world.

We have the potential to be the first superpower African country and we are currently focusing on so many irrelevances that it's mind boggling.

Critics of Nigeria have ensured that all Nigerians are familiar with the negatives of Nigeria. Actually critics have been so effective that it has become as if the entire world is familiar with these negatives. I’m sure I’m not the only one occasionally surprised by some foreigners’ expert negative opinions on Nigeria. It is a wonder then that some Nigeria critics on this thread find others unreceptive when they criticise. A poster (Lurker4Long ) even uploaded a Fela video – possibly not the Lurker4Long’s intention but the vid reinforces this observation that criticism of Nigeria has a long history. We get it - disgusts, anger and disappointment with the way things are is in the DNA - and maybe some of us would appreciate a fresh approach to these criticisms of all aspect of Nigeria and Nigerianess supposedly intended as a kick in the direction of positive change. A less stale approach may be for all future such “motivational” speeches and writings to include positives that counteract the debilitating and morally exhausting negatives. Battling negatives is possibly easier when invigorated by positives.

So, Yulaw, if you’re not offended by my asking, what would you suggest are the Nigeria's positives we all should be aware of in order that we may preserve them and improve on them even as we are reminded of the negatives that we all must fight to reverse?

Beancounter94:
We still have a long way to go with sports development...so any medals won while nice, still does not mean all is well.

Apart from football, sports development in Nigeria is abysmal. Always has been. We have to raise talent, have to raise funding, have to raise expertise. We need more and more and more people playing a variety of sports.

Ones in a while, moneyed individuals, altruistically building facilities for the leasure of young people, helps. What would it cost some of the wealthy individuals that rather spend millions on arms to militants, or political goons, simply erecting domes with artificial hills, deeps and valleys for young people to play in equipped with skate boards and climbing equipment, bmx cycles for hire, shooting galleries, archery, snooker or billiards, bowling alleys etc, etc?

I used to attend an ice skating arena where i lived. For a pound you’d be provided with skating boots brought out from the store room to use for an hour or so. Domes are simple yet effective and pleasing looking structures to build. State governors could build lots of domes that cater for wide variety of sports for young people to try. People in the community for whom they are built will help fund some of the maintenance by being charged affordable small amounts of money or in exchange for helping around the place .

There's so much to do in Nigeria, so much opportunity due to so little on the ground, that militancy should be the last thing on any young persons’s mind.

I bet that within just 4 square miles of wherever anyone lives in the UK there are more facilities for young people to go do sports leisure activity than all of Delta state Nigeria for instance.

You're being somewhat dishonest or you know nothing about Nigeria, which is one of few nations where wealthy people are worshiped not maliciously envied or hated.

“Some of those kidnapped and released said the herdsmen insisted that they would continue there until IPOB leader, Nnamdi Kanu, dropped his agitations for Biafra,” he said.


https://dailypost.ng/2021/08/04/herdsmen-kill-eight-in-another-enugu-attack-blame-nnamdi-kanu-ipob/

Unless this line was added for seasoning sake, by someone unimaginative, it rather cast doubt on the authenticity of the event.

I'm not suprised. The echelons of Nigeria sports need to recognise the importance of psychology in sports and implement such in our system. For some reason, Nigeria sportsmen and women, unlike Nigerians generally, seem afflicted by self-doubts inversely disproportional to their actual abilities. And they nether posses shear bloody-mindedness. Blessing is for me an example, this track star had the ability and stature to break the women’s 100m world record or merely achieve far more than she has archived in the sports. I’ve been a track and field super fan for a long time and have developed a keen eye for even the smallest aspect of it. Blessing had the habit of becoming aware of her competitors midway through a race instead of concentrating on running her own race and focusing on the finish line as is thought. Her worst races were due to this habit. On becoming aware of her competitors she would stiffen up or loose self belief in her ability to speed up towards the second half the race.

Probably new set of bandits, others will wait their turn for payment after this lot are paid. Like I said years ago, it may cost much money to put in proper infrastructure, for instance border fences, first world standard schools and police stations, (eradicate bandits when you identify them forget their revenge strategy, just gun them down always). but you’ll recoup the cost in the long run. Piecemeal bandages measures work out costlier in the end.

Lay down border fences as other nations have done –Pakistan being the latest nation to do so with appreciable results – forget brotherliness and all that shared ethnicity crap. Nigeria is your team. It always amuses me when some idiot talks about uniting with ethnicities he or she shares with strangers in far-far Niger or Benin republic but get hold of him or her, interview them, and you’ll soon find out that they have blood relatives in Nigeria that they don’t even communicate with, they hate or would like to kill given the opportunity.
