Ligue 1 side Olympique de Marseille confirmed last night that French international central midfielder Lassana Diarra had left the club after both parties agreed to the termination of his contract.
Following on from discussions between President Eyraud and Diarra, the former decided that the latter’s motivation to continue in a Marseille shirt was not strong enough without satisfying Diarra’s demands for a new contract and for OM to pay the player’s fine that he has incurred in a wage dispute with Lokomotiv Moscow.
As a result, Eyraud decided to allow Diarra to leave the club on a free transfer, in a deal that has seen Marseille pay the player nothing in the way of compensation. Diarra will now hope that he can seal a move to China before their transfer deadline on the 28th of February.
The former Arsenal and Chelsea man is said to be in advanced talks with Shandong Luneng Taishan, according to a report from La Provence last night.
Patrice Evra had attempted to convince Diarra to stay, but he goes, a little over 18 months after arriving at the club. Many will forget, but his performances in the first six months of the 2015/16 campaign were nothing short of remarkable.

在北京时间9月9日的报道中，金州勇士队的后卫斯蒂芬-库里最近在一次采访中分享了他参加奥运会的体验。
谈及自己奥运会前期的手感低迷，库里说道：“这是积极的自我调侃。我们在赢球，我也在尽自己的职责，设置掩护，打得强硬，但我没有投篮命中。我知道在某些时候我需要投进一些球，因为这就是我来这里的原因。
“在我们与波多黎各的比赛结束后，我接受了采访，他们问我：'你的投篮怎么了?你担心吗?'我说，'不，我们正在赢球，我知道一波高潮即将来临。’我刚说完，勒布朗就走到我身后说，‘太对了，就是这样。’这给了我很大的信心。
“这也让我措手不及，因为你知道，在我们所有的战斗之后，我不得不习惯于喜欢那个家伙。但这让我信心倍增，而且来得正是时候。”

We talked last time about five reasons why the advent of so-called “driverless” cars would be a great idea. But for those of you out there with a skeptical bent, we would like to present the other side of the story. Here then are the top five reasons why self-driving cars will be the ruin of us all.
No reasonable person would argue against the obvious safety advantages of a vehicle that can anticipate, react and avoid danger much faster than any human, and without driver error. What’s not to like? But consider that to achieve this level of infallibility will require not only a vast sensor array, but a complex series of pre-programmed responses which, ultimately, approach the complexity of artificial intelligence. In other words, cars at least as smart as we are in this strategic regard.
At the same time, their automatic systems will continue to render our own skills obsolete, much as rear-view cameras are now creating a generation of young drivers who don’t know how to parallel park without them. The ultimate expression of this trend, therefore, will be incompetent drivers, not skillful ones. Less safe, not more.
And where will it end? As soon as AI cars realize that safety is one of their programmed priorities, they may tell us: “Don’t get in the car.”
Everyone assumes that our robot overlords will drive more efficiently than we mere humans possibly could, given that they will calculate time, distance, speed and direction with mathematical precision. Well, not so fast. The ostensible benefits of self-driving cars is that they will be smooth and comfortable, faster, and will reduce traffic congestion. It turns out these benefits can be antagonistic and even self-defeating.
A study was recently done by researchers at the City University of New York and Imperial College, London. This study demonstrated that, if we want our autonomous cars to start and stop smoothly (which is mechanically efficient and comfortable and safe), then they will also need to accelerate and brake more slowly and over a larger area, thus reducing road capacity and increasing following distances in the process. If you want speed, cars must go faster and brake later and be more tightly bunched together – which is indeed faster but is less safe and consumes more gas. In all of the computer simulations in which a driverless vehicle was pitted against its manually-operated counterpart, the robot car either created more congestion or was slower. Turns out, at least one of the parameters has to give to make way for the other two. Also note that this is in an ideal setting, not taking into account the unexpected road hazards out there. We human drivers, so far, are already much more efficient in the real world.
Here again is an example of limited thinking. The presumption is that, if we are free from the chore of driving, we can then turn our attention to work, say on our laptops. Which will then give us more time to get things done, making us more relaxed and productive.
Hold it right there. Automation and computers were supposed to revolutionize the world of work a long time ago, freeing us from drudgery and giving us all more leisure and creative time. They’ve been saying this since the 1950’s. But now people in the advanced countries – those who would use self-driving cars in the first place- are more overworked than ever, putting in longer hours, taking fewer vacations and yet still being expected to be ever more productive.
Put simply: nature abhors a vacuum. If you have more time available each day to work, you will be given more work to do. Soon enough that commute time will be calculated as part of your working time, and you will be held accountable for how you use it. Is this what we really want? You won’t be more relaxed, you will be more consumed with work.
Robo cars could be a boon for the physically handicapped, the aged or the infirm. That is, if they can afford such a car in the future. Right now the technology is prohibitively expensive, but surely the cost will come down as the industry scales up.
What about other marginalized groups? Will such cars be available to the very young, or to those with DUI records? This is all very uncertain, but what is certain is that the technology is being touted by huge multinational corporations that have a vested interest in selling more cars and the technology to control them. Accessibility means profits. GE and Ford and Google are not interested in a population that commutes on foot or uses bicycles, so they want to convince us all that this is the only solution to the problems of our overcrowded roadways – make more cars!
Why don’t we rethink the way we build our cities, and invest that same R&D money into non-profit clean public transit? We are so dazzled by the technical wizardry that we’re not paying attention to the man behind the curtain. Pssst. Here’s a secret. The accessibility they’re thinking of is access to you. The autonomous car will be monitored 24/7. Someone wants to know where you go, when you go there, how long you stay there, etc. This Big Data will be used to market products and services at the very least. No longer will the car be a ticket to freedom and independence. It will be a slot car, on rails, taking you directly to the mall so your wallet can be emptied.
Driving well – that is, safely and efficiently – is a skill that exists at the intersection of training, experience, emotional control, physical competence and a reliable machine. There are costs and trade-offs associated with acquiring and using this skill. The benefits to the skilled driver include hand-eye coordination, precise timing, peripheral awareness, anticipation and response, and a sophisticated, even instinctive harmonizing of essential forces involving friction, inertia, momentum and acceleration. This tactile and analog skill set can translate to other tasks and other types of machine-human interface in our mechanized world.
Dumb driving comes about as a failure in one or more of these areas. We can either invest in better training, safer cars and better roads, or alternately supplant the driver’s skill altogether with servo motors and a robot brain. All of the skills associated with learning to pilot the machine will atrophy in a few years, to the detriment of anyone who wants to be a participant and not a spectator.
It doesn’t bode well for us as a people to be ever more isolated, dependent, anti-social and sealed inside metal boxes we can’t even control and don’t know how to. We’re making the machine smarter, and ourselves dumber.
So there you have it. Ten arguments about self-driving cars, half pro and half con. Do you have an opinion, or is there something we missed? We’d love to hear about it. Contact us.

Wondering what to get your aspiring scientist or engineer this year for Christmas? Well fear not, because thankfully now is a golden age for STEM toys and gifts to inspire young learners to experiment, play and discover the pleasures of figuring out how things work. We like to support more people to get involved in the world of inventing and making, so here is our countdown of the top eight science, technology, engineering and mathematics gifts for Christmas 2017.
Physics deals with the fundamental forces of nature and how they interact. This awesome gift has a clear instruction book and tons of practical, hands-on experiments that demonstrate the principles that govern how things move they way they do. All essential knowledge for every field of engineering and applied science.
Skills Learned: Momentum, kinetic and potential energy, mass, force, inertia
A perfect complement to physics is the study of chemistry, which is all about the behavior of elements and molecules and how they change state under different conditions. Sound intimidating? This chemistry set makes it easy, with clear instructions for forty experiments using safe household supplies like vinegar, soap and even cabbage.
Learn about fluid dynamics and pressure, heat exchange, pH balance and much more. Not only is it instructive but it looks like you have your own mad scientist movie laboratory.
Skills learned: Acids and bases, heat transfer, phase changes, fluid dynamics, pressure and volume.
It’s often said that engineering is applied mathematics, but math by itself can be hard for young learners to grasp conceptually. This gift not only helps to make it easer to understand math concepts but also to appreciate the beauty underlying the patterns of the physical world.
No need for batteries, smartphones, apps or even electricity, Spirograph is a classic gift that still fascinates and teaches more than fifty years after it was first introduced.
Turning mathematics into works of art, the Spirograph uses a series of geared wheels within wheels to generate an almost infinite variety of complex patterns that bring basic mathematical relationships into colorful life.
After all, many math concepts can be expressed in the forms of symmetry and repeating patterns. Like the best gifts it’s simple in principle, infinite in application and timeless in its appeal.
Skills learned: Balance, proportion, patterns, fractals, spirals, spatial reasoning, design
Taking abstract thinking into the next dimension is the Zometool. Inspired by pioneering work in architecture and mathematics, the Zometool owes its genius to the many-faceted ball joints that hold the different struts together.
This ball has different shaped slots to hold the mating struts at precise angles. Following a few simple rules for constructing a starting cube, a limitless variety of derived shapes can be formed around it. We like this one because it sets you free to create without a blueprint, but still maintains the kind of discipline needed in all good design work.
Now Zometools are used by educators, Nobel prize winners and architects to model geodesic domes, molecules and proteins. How many shapes can you make? No one has figured out all the possibilities, yet.
Skills learned: Creativity, geometric and spatial reasoning, design
We live in a tech world, so to get young people prepared for a life with technology means helping them to understand the language of computers and electrical circuits. Thankfully that’s easier and more fun to do than ever before with this innovative and interactive gift.
The Neuron is an award winner in many ways. First there’s a group of discrete components like on/off switches, lights, speakers, cameras and more which can be clicked together to build any number of devices. But to make circuits that work properly, children need to also use a simple programming tool on a tablet. Expansion kits add to a growing list of components and there are online competitions to see who can make the coolest designs. Learning to program a computer was never this much fun.
Ok, now we’ve covered the basics of physics, chemistry, math and electronics. Time to start making some machines! What exactly is a machine? A device that multiplies or transfers force over a distance.
All sophisticated machines are merely extrapolations of a few simple types, so this is a great way to establish a firm foundation in the mechanical arts. Basic mechanisms include levers, gears, pulleys, cranks and cams. From these,
budding mechanical engineers can build more than 60 machines that will teach them the practical applications of force, mechanical advantage, gear ratios and drive mechanisms.
Skills learned: Gear ratios, levers, pulleys, wheels and axles, mechanical advantage, inclined planes
Ready to take it to the next level? Robotics combines mechanical and electrical engineering with computers to create machines that you control remotely or that can follow programmed commands.
A detailed instruction book explains how to build twelve sophisticated robots to perform a variety of tasks, but with your imagination you can build many more. A smartphone or tablet is used to access the free app for controlling the robot, which is also being constantly updated with improvements.
Learn how to use motors and sensors to control your robot, help it to avoid obstacles, sound warning alerts or lift heavy objects. After all, robots are going to take over the world so it’s a good idea to make friends now while you still can.
Skills learned: Sensor technology, ultrasonics, servo motion, control programming, mechanical dexterity
The original Ferris wheel was the brainchild of bridge builder George Ferris and served as the main attraction at the World Expo in Chicago in 1893. Now it can be the main attraction in your home with the biggest and baddest K’NEX set ever offered.
Standing over six feet tall, this mother of all construction sets contains 8,500 snap together pieces and three instruction books. This very challenging construction project teaches structural engineering along with patience and the ability to follow complex instructions. Imagine the sense of accomplishment and wonder when your child plugs it in, switches on the LED lights and watches it come to life. Worried that your kids will get bored with their toys a week after Christmas? Not with this one.
Skills learned: Eye-hand coordination, following instructions, patience, dexterity, structural engineering concepts
What Christmas would be complete without a new Star Wars gift? But not just any Star Wars toy, this is the ultimate LEGO Millennium Falcon, one of the most complex and challenging sets LEGO has ever made.
With more than 7,500 pieces, a detailed interior and eleven movie figurines, this spaceship will launch a thousand new adventures in a galaxy very close to home. Admit it, you want one.
We believe that in our changing world everyone needs to be well-versed in basic science and engineering, and these toys and gifts show that it’s fun and easy to do just that from an early age. We use these same skills and concepts every day in manufacturing the next generation of cool products, and we’d like to do the same for you. So bring us your design ideas and we’ll offer you a free quote to get started. Merry Christmas!

Speaking to reporters following PSG’s 6-1 debacle against FC Barcelona that saw them crash out of the Champions’ League, PSG President Nasser Al Khelaifi attempted to piece together the situation.
“I cannot believe what has happened… we conceded three goals with seven minutes… We are not going to look for excuses but there are two penalties and twice there wasn’t a penalty… We played very badly. It is difficult to accept. It is very very hard. The referee helped Barcelona a lot. It is difficult to accept. It is a nightmare for everyone. Everyone is annoyed. Is Emery in trouble? That is not even a question.”
