Breakthrough brings ‘Star Trek’ teleport a step closer

Scientists have set a new record in sending information through thin air using the revolutionary technology of quantum teleportation - although Mr Spock may have to wait a little longer for a Scotty to beam him up with it.

A team of physicists has teleported data over a distance of 89 miles from the Canary Island of La Palma to the neighbouring island of Tenerife, which is 10 times further than the previous attempt at teleportation through free space.

The scientists did it by exploiting the “spooky” and virtually unfathomable field of quantum entanglement - when the state of matter rather than matter itself is sent from one place to another. Tiny packets or particles of light, photons, were used to teleport information between telescopes on the two islands. The photons did it by quantum entanglement and scientists hope it will form the basis of a way of sending encrypted data.

How to survive in a black hole
There’s no escape, but how can you maximize your remaining time?

So there you are: you discover that your spaceship has inadvertently slipped across the event horizon of a black hole — the boundary beyond which nothing, not even light, can escape the hole’s fearsome gravity. The only question is how you can maximize the time you have left. What do you do?
A common idea in physics is that you shouldn’t try to blast your way out of there. Black holes, it’s said, are like the popular view of quicksand: the harder you struggle, the worse things become.

But Geraint Lewis and Juliana Kwan of the University of Sydney in Australia say this is a myth. Their analysis of the problem, soon to be published in the Proceedings of the Astronomical Society of Australia(1), shows that in general your best bet is indeed to turn on the rocket’s engine. You’ll never escape, but you’ll live a little longer.

Falling into a black hole is a strange affair. Because the hole’s gravity distorts space-time, a far-off observer watching an object crossing the event horizon sees time for that object appear to slow down — a clock falling into a black hole would appear, from the outside, to tick ever slower. At the horizon itself, time stops, and the object stays frozen there for the remaining lifetime of the Universe.

If you want to succeed as a leader, you can only do it by setting up your team members to succeed. Here are a few fundamental leadership tips for managing your team to peak performance. Keep in mind that these tips are aimed at leaders who manage knowledge workers and project managers in IT. The equation can be a little different if you are managing people in a strict production environment, although many of the principles may still apply.

#1: Focus on results and productivity and not the time clock

When you manage salaried knowledge workers, you should almost never have rigid clock-in/clock-out times unless there is a coverage issue in relation to serving customers (e.g., maintaining adequate help desk coverage during call hours). Instead, set clear goals that you know should take your employees about 40 hours/week to accomplish. Require that they show up on time for important meetings and are available during the team’s general working hours. Provide them with the tools to access their work remotely, when needed. Then let them manage their own time. This sends the message that you trust your employees. If you’ve got people you don’t trust, that’s another issue. Manage them up until you do trust them or manage them out to their next opportunity.

#2: Align people with the stuff they are good at

Make sure you have the right people in the right seats. This is especially true if you take over the management of a team that is already in place. Take stock of all the talents you have on the team and reshuffle the deck if it means that your team has a better chance of success. Don’t keep someone in a job role just because they’ve been doing it for long time if you truly think their talents are better suited and could make a bigger contribution in another role. Employees might be reluctant to move in a case like this, so you may need to work hard to convince them that the change is in their best interest, as well as the best interest of the company.

Menariknya huruf ini dalam urutan standart-nya jika diucapkan sebenarnya mengandung arti, pengucapannya begini

hana, caraka

yang artinya: “Ada pengikut (prajurit) yang bertentangan (berbeda pendapat) sama saktinya keduanya mati”. Ada semacam legenda yang menceritakan kisah dari Versi panjang dari cerita ini adalah

Pada jaman dahulu ada seorang raja yang mempunyai 2 orang pengikut setia, kedua-duanya adalah pengawal yang sangat sakti. karne gejolak didalam kerajaan nya, suatu hari sang raja memanggil salah satu pengawalnya dan menitipkan sebuah keris kepadanya dan berpesan “Pergilah bawalah keris ini, dan jangan berikan kepada siapapun selain aku”, setelah itu pergilah pengawal yang setia itu. beberapa tahun kemudaian sang raja memanggil pengawalnya yang lain dia memerintahkan untuk mengambil keris tesebut. Maka berangkatlah si pengawal tadi dan bertemu dengan temannya, ketika dia meminta keris tersebut temannya teringat akan pesan sang raja, bahwa siapapun yang mengambil keris tersebut selain dirinya tidak boleh. Maka keduanya ribut mempertahankan pendapat, dan kesetiaan mereka terhadap tugas yang diembannya, maka terjadilah pertarungan diantara keduanya, dan kerena kesaktian mereka yang seimbang, mereka saling bunuh dan kedua duanya mati. Kemudian sang raja menyesali ke keliruannya dan dia mengucapkan “hana(ana) caraka, data sawala padha jayanya maga bathanga”
