Proving 2 temperatures coexist — disrupting thermodynamics.
Stuart Wolpert.
According to the basic laws of thermodynamics, if you leave a warm apple pie in a winter window eventually the pie would cool down to the same temperature as the surrounding air.
For chemists and physicists, cooling samples of charged particles, also called ions, makes them easier to control and study. So they use a similar approach — called buffer gas cooling — to lower the temperature of ions by trapping them and then immersing them in clouds of cold atoms. Collisions with the atoms cool the originally hot ions by transferring energy from the ions to the atoms — much the same way a warm pie is cooled next to the cold window, said Eric Hudson, associate professor of physics at UCLA.
Want your own lightsaber? with this printer you can have your own.
This 3D-printable custom lightsaber is truly a thing of beauty. Here’s how you can make your own.
BMW is a German car manufacturer that has decided to make use of 3D printing technology in order to restore the BMW 507 racecar of Elvis Presley. Through additive manufacturing technology, they were able to reconstruct the window winders of the car as well as its door handles.
For sure, Elvis never anticipated that his racecar which he purchased in 1958 will be restored after 60 years with the help of a 3D printer. Jack Castor owned the vehicle and was purchased by BMW Group Classic 2 years ago and kept it in the pumpkin factory.
Excellent write up on QUESS; and yesterday we saw that the first set of code was transmitted successfully which means so far success. However, many are asking when will the US respond about our own efforts around our own efforts of a Quantum satellite and our own progress around improving the net infrastructure to ensure we’re not a sitting duck for government backed hackers. Granted we have been operating for many years a version of a Quantum Internet at Los Alamos; however, we need to expand and accelerate the efforts around the Quantum Internet restructuring.
In mid August China launched “QUESS” (Quantum Experiments at Space Scale), a new type of satellite that it hopes will be capable of “quantum communications” which is supposed to be hack-proof, through the use of “quantum entanglement”. This allows the operator to ensure that no one else is listening to your communications by reliably distributing keys that are then used for encryption in order to be absolutely sure that there is no one in the middle intercepting that information.
According the Chinese scientists involved in the project, quantum encryption is secure against any kind of computing power because information encoded in a quantum particle is destroyed as soon as it is measured. (According to Tibor Molnar a scientist at the University of Sydney), the only way to ‘observe’ a photon is to have it interact with (a) an electron, or (b) an electromagnetic field. Either of these interactions will cause the photon to “decohere” – i.e., interfere with it in a way that will be apparent to the intended recipient.
Gregoir Ribordy, co-founder of Geneva-based quantum cryptography firm ID Quantique, likened it to sending a message written on a soap bubble. “If someone tries to intercept it when it’s being transmitted, by touching it, they make it burst.”
Experiments confirm the existence of 1-micrometer-sized molecules made of two cesium atoms by showing that their binding energies agree with predictions.
Strongly bound diatomic molecules such as H2H2or O2O2 are less than a nanometer across. Surprisingly, scientists have been able to create two-atom molecules more than a thousand times larger by using exotic atoms that attract one another only very weakly. Now, a pair of physicists have calculated what makes these “macrodimers” stable, and they have verified their predictions by creating micrometer-sized molecules containing two cesium atoms. The macrodimers could have applications in quantum computing.

A write-up from Popular Science on the bioethics conference I was a part of recently and the corresponding 2-min highlight video. It was truly a fascinating event, inspired by Deus Ex! http://www.popsci.com/augmented-reality-or-augmented-humanity And here’s the video: http://www.dailymotion.com/video/x4p7uld_human-by-design-conference-recap_tech
With the release of the new video game, Deus Ex: Mankind Divided, Human By Design holds a conference to discuss the future of human augmentation.
Researchers have created a way of letting next-gen wearables and implants communicate with the outside world using 10,000x less power than regular Wi-Fi.
