Swanzi:True. My annoyance is that Nigeria did not close the borders tight enough. This may change hopefully since, recently, Nigeria state governors convened a meeting aimed at recommending to presidency measures for mitigating many of our security difficulties. I was glad to see that among their top recommendations was the creation of Border Security Force. Hopefully Nigeria will be able to close the borders much more effectively. Nigeria needs to keep Ghanaians, Malians, Chadian, Nigeriens and others out. |
Pierocash:It’s often said that the State’s primary function is the provision of security; Wiki seems to have perfomed well here. His state seems to be bucking the national rising insecurity trend. And he seems to have many ideas on how to deal with current and future insecurity issues. |
AllenSpencer:Nigeria needs a none military Strong Man and Wike seems strong, but I’m willing to learn without prejudice and understand Nigeria politics better. |
Delta state gave Nigeria Oil and kidnapping industry, what did your state give Nigeria? |
donbachi:If Gods exist, they'll likely punish the kidnappers instead of the leaders. |
When many kids were running around playing tag or video games, Chanda Prescod-Weinstein was thinking about particle physics. After her mother took her to see "A Brief History of Time," Errol Morris' 1991 documentary about theoretical physicist Stephen Hawking, she fell in love with the discipline. She was just 10 years old. Nearly 30 years later, she is the first Black woman to hold a tenure-track faculty position in theoretical cosmology as an assistant professor at the University of New Hampshire. Prescod-Weinstein is one of the country's few core faculty members of both physics and women's and gender studies departments at a higher institution. In her new book, "The Disordered Cosmos: A Journey into Dark Matter, Spacetime, and Dreams Deferred," Prescod-Weinstein invites readers into the universe as she sees it -- and as a self-described queer agender Black woman, she sees it differently than many people. Her book chapters -- including "The Physics of Melanin," "Black People Are Luminous Matter" and "The Anti-Patriarchy Agender" -- show her focus "at the intersection of astrophysics and particle physics" and at the intersection of physics and Black feminist thought and anti-colonial theory. Her book is a tour of particles like quarks and leptons, as well as the axions that Prescod-Weinstein specializes in, but it also explores the various structural oppressions that affect who gets to study and discover them -- and even who gets to name those discoveries. She points to terms like WIMP -- weakly interacting massive particles -- and its relative MACHO, or massive astrophysical compact halo objects, as examples. "You can tell that physicists love an acronym," she wrote, "and that the physicists who came up with WIMP and MACHO were almost certainly men." Women and people of color, she notes, are routinely left out of histories of science, despite their important role in the progress that White men are credited with making. Prescod-Weinstein asks us to consider how science would be different if scientists were from more diverse backgrounds, and if it incorporated Indigenous scientific knowledge and voices. We spoke to Prescod-Weinstein about her ideas and her hopes for future scientists. This conversation has been lightly edited for clarity. CNN: The subtitle of your book combines dark matter, space-time and dreams deferred. How do those three things intersect for you? Chanda Prescod-Weinstein: I'm a dark matter expert, and so of course, the dark matter -- an invisible form of matter that we believe comprises 80% of the universe -- is going to figure into it in some big way. And dark matter exists in this larger context of space-time, which is how Einstein's theory of relativity requires us to think of space and time, as existing in relationship with each other. I also wanted to be honest that this was going to be part of the larger social context and not just the larger physical context. That larger social context is dreams deferred. That is both a comment on the social issues that I raise in the book, but also a comment on having to raise the social issues. https://www.cnn.com/2021/05/02/world/black-scientists-structural-racism-scn-wellness/index.html |
The move to a three-node system is a quantum leap in network design Scientists have gotten one step closer to a quantum internet by creating the world's first multinode quantum network. Researchers at the QuTech research center in the Netherlands created the system, which is made up of three quantum nodes entangled by the spooky laws of quantum mechanics that govern subatomic particles. It is the first time that more than two quantum bits, or "qubits," that do the calculations in quantum computing have been linked together as "nodes," or network endpoints. Researchers expect the first quantum networks to unlock a wealth of computing applications that can't be performed by existing classical devices — such as faster computation and improved cryptography. "It will allow us to connect quantum computers for more computing power, create unhackable networks and connect atomic clocks and telescopes together with unprecedented levels of coordination," Matteo Pompili, a member of the QuTech research team that created the network at Delft University of Technology in the Netherlands, told Live Science. "There are also loads of applications that we can't really foresee. One could be to create an algorithm that will run elections in a secure way, for instance." In much the same way that the traditional computer bit is the basic unit of digital information, the qubit is the basic unit of quantum information. Like the bit, the qubit can be either a 1 or a 0, which represent two possible positions in a two-state system. But that's just about where the similarities end. Thanks to the bizarre laws of the quantum world, the qubit can exist in a superposition of both the 1 and 0 states until the moment it is measured, when it will randomly collapse into either a 1 or a 0. This strange behavior is the key to the power of quantum computing, as it allows a qubit to perform multiple calculations simultaneously. Related: The 18 biggest unsolved mysteries in physics The biggest challenge in linking those qubits together into a quantum network is in establishing and maintaining a process called entanglement, or what Albert Einstein dubbed "spooky action at a distance." This is when two qubits become coupled, linking their properties so that any change in one particle will cause a change in the other, even if they are separated by vast distances. You can entangle quantum nodes in a lot of ways, but one common method works by first entangling the stationary qubits (which form the network's nodes) with photons, or light particles, before firing the photons at each other. When they meet, the two photons also become entangled, thereby entangling the qubits. This binds the two stationary nodes that are separated by a distance. Any change made to one is reflected by an instantaneous change to the other. "Spooky action at a distance" lets scientists change the state of a particle by altering the state of its distant entangled partner, effectively teleporting information across big gaps. But maintaining a state of entanglement is a tough task, especially as the entangled system is always at risk of interacting with the outside world and being destroyed by a process called decoherence. This means, first, that the quantum nodes have to be kept at extremely cold temperatures inside devices called cryostats to minimize the chances that the qubits will interfere with something outside the system. Second, the photons used in the entanglement can't travel very long distances before they are absorbed or scattered, — destroying the signal being sent between two nodes. "The problem is, unlike classical networks, you cannot amplify quantum signals. If you try to copy the qubit, you destroy the original copy," Pompili said, referring to physics' "no-cloning theorem," which states that it is impossible to create an identical copy of an unknown quantum state. "This really limits the distances we can send quantum signals to the tens of hundreds of kilometers. If you want to set up quantum communication with someone on the other side of the world, you'll need relay nodes in between. https://www.livescience.com/three-node-quantum-network.html |

Elize Lutz, 70, and Harrie Dekkers, 67, retired shopkeepers from Amsterdam, received their digital key – an app allowing them to open the front door of their two-bedroom bungalow at the press of a button – on Thursday. “It is beautiful,” said Lutz. “It has the feel of a bunker – it feels safe,” added Dekkers. Inspired by the shape of a boulder, the dimensions of which would be difficult and expensive to construct using traditional methods, the property is the first of five homes planned by the construction firm Saint-Gobain Weber Beamix for a plot of land by the Beatrix canal in the Eindhoven suburb of Bosrijk. https://i.guim.co.uk/img/media/a9882304e797fb1308947f0b51b4284fcecce860/0_174_5892_3535/master/5892.jpg?width=940&quality=85&auto=format&fit=max&s=f4240ea66eb4e56b210287b2dbf745f6 In the last two years properties partly constructed by 3D printing have been built in France and the US, and nascent projects are proliferating around the world. But those behind the Dutch house, which boasts 94sq meters of living space, are said to have pipped their rivals to the post by being the first legally habitable and commercially rented property where the load-bearing walls have been made using a 3D printer nozzle. “This is also the first one which is 100% permitted by the local authorities and which is habited by people who actually pay for living in this house,” said Bas Huysmans, chief executive of Weber Benelux, a construction offshoot of its French parent company Saint-Gobain. https://www.theguardian.com/technology/2021/apr/30/dutch-couple-move-into-europe-first-fully-3d-printed-house-eindhoven |
nowhere:It is estimated that population of Nigeria is approximately 210 -300 million, South Africa is approximately 59 million. The chances of me being kidnapped in Nigeria is slimmer than me being killed in South Africa, if I lived there. In spite of our insecurity issues, you’re safer in Nigeria than South Africa. |
nowhere:Excuses... |
ifytrik:You'll celebrate the death of any Nigerian policeman or woman because you spent a night in a cell and was find 5k? (£11.00p) ![]() Mister, you’re giving the impression that you’re a bankrupt! |
ugo4u:Not a leveler, more a retrogradinger. I’ve just left a thread where the majority of respondents – presumably Nigerians - don’t know that there are insurance companies in Nigeria. Millions of this type of mindset will work to bring Nigeria down mainly out of ignorance of their own Nation. They are the types that might cry, ‘South Africa and Kenya have Insurance companies, common Insurance company, we don’t have in this country, oh why did god let me be born in this shithole Nigeria!’ Like this, millions of ignorant, negative voices help create and facilitate despondency that empowers anti-state actors |
golddust6000:He's an IT guy but doesn’t know that there are loads of insurance company's in Nigeria one can google up ? ![]() |
If government could track down online instigators, arrest and prosecutes some of you, Nigeria will go a long way in solving some of these insecurity problems. |
Winnerforever:So from your troll house in kumasi somewhere you know better.... |
If government could track down online instigators, arrest and prosecutes some of you, Nigeria will go a long way in solving some of these insecurity problems. For insistence, Social media played and plays a massive role in demoralising the Nigeria military fighting men and women. |

Does this mean SARS was responsible for holding Nigeria together? Because, I gat ta tell ya, from an outsiders perspective, since publicly revoked, insecurity in Nigeria seems to have attained a vertical acceleration on the graph from its former steady upward sloping trajectory. |
NafeesaAA:My grandparents did same when Nigerian soldiers entered a village in the East where they where in refuge during the last days of the Nigeria civil war. The effective Biafra propaganda machine had long since convinced everyone in the East of the dire consequences of Nigeria soldiers’ occupancy of Igbo towns and villages. Naturally as Nigerian troops rolled in, my grandmum and all the villagers considered themselves finished and yet they cheered and waved raffia, wrappers, even small children, anything they could, they waved in celebration. They did this in terror, to placate the soldiers and to give the impression that they are on the side of forces occupying the area. You’ll find this behaivoyur in all conflict zone, it is a universal response. |
Great development. |
Covert1:Nigerians need to call for suspension of that 1.8 billion dollar rail to Niger Republic. |
Fejoku:Deadly people come in all shape and size; you’ll find them also in the police and in the army if the time you’re raving and hoping for arrives. |
Faithful007:With 10,000 US troops stationed in Nigeria, what position do you imagine America would take in Nigeria’s burgeoning Biafra separatists’ militancy? |
SamuelAnyawu:400Million Dollars on humanitarian issues in Borno state - a cynic might retort, 'no wonder there’s no end of problem in Borno!'. In my early teens, I recall adult Nigerians arguing that reliance on Aid was impoverishing East Africa by creating reliance and personal gains at the top echelons from Aid money. Thought Nigerians had more sense and dignity than to play that old Aid game. |
Faithful007:I don’t mean they, China, will have boots on the ground, I mean for Nigeria to engage with them in all other respects, such as our officers and generals visiting China and inviting theirs to Nigeria; Back China in the UN and political support in the international arena; entering military pacts; working with them on defence planning and setting up systems in Nigeria that America dislikes. Whatever America dislikes Nigeria acquiring is that which is good for Nigeria to have in place. We may need to do all the initiating but Nigeria should abandon her none aligned polices. Nigeria is too insistent on playing the third world pickaninny . We are way too big for khaki shorts. You refuse to grow up, little boys go dey chook you finger for forehead. |
Nigeria needs to stop being blackmailed by Civil War threats. Leadership need to go in hard on miscreants and if Civil war results then so be it, at least civil war will provide opportunity to clean up the mess. We need to get up off our knees and stop pandering to these militant interest groups. If we must go out lets go out with such mayhem that it will be our last gift to Africa that of lessons why Wars are stupid, unproductive and on which they must turn their backs and discard as anachronistic and primitive. |
Closer military ties with China would serve Nigeria better than the old tired, unproductive dalliance with US that we, in any case, nowadays do out of fear. Nigeria mustn’t trust any of the Western nations; there’ll be no improvements just a steady even accelerated disintegration. We are hamstrung now as it is because of the West and their weponised liberal impositions. |
horsepower102:Eh, African Americans need to heed your advice. In fact, the entire world needs to heed your advice; oya Brazilians, Americans, Chinese people, South Africans, Kenyans, UK Blacks, French Senegalese and Arabs start ambushing and killing your police and military officers ... lets see how that turns out.... The Nigerian state is way, WAY, too lenient with her wild, truly arkata, population.... |
Faithful007:No, I’m suggesting away from advice given, we (among Nigerians only) study where potential traps may arise, before proceeding. |
