The Hubble Space Telescope allowed scientists to observe what looks like a clump of dark matter which is what remains after a cosmic catastrophe that led to a merger of galaxy clusters. The result is called the Abell 520 cluster, an abnormal cosmic structure which has a chaotic nature exactly because it’s the result of a collision between galaxies.
The Raspberry Pi is a tiny computer the size of a credit card. That’s a project started about six years ago that has now finally seen the light. Yesterday its sales started and the success has been incredible, so much that the available computers were sold very quickly. The official project website was taken down because of the excessive traffic and the sites of its partners who resell the Raspberry Pi suffered high traffic problems.
The team at IBM Research made very important progress in reducing the error in elementary computations and in maintaining the integrity of the quantum properties of qubits. A key element in the production of superconducting qubit was to use manufacturing techniques developed for the production with silicon currently in use.
