Gravitational Lensing is a natural phenomenon that magnifies light around galaxies.  The phenomenon occurs when a huge amount of matter, such as a massive galaxy or cluster of galaxies, creates a gravitational field that distorts and magnifies the light from objects behind it, but in the same line of sight. This makes dim, faraway objects … Read more

  Miniaturisation of the transistor size. Smaller, faster and better transistors may mean that soon your computer’s entire memory may be stored on a single tiny chip. Using magnetic random access memory (MRAM), computers will be able to “boot” almost instantly. MRAM is enabled by nanometer‐scale magnetic tunnel junctions and can quickly and effectively save … Read more

A quantum computer employs the principles of quantum mechanics to store information in ‘qubits’ instead of the typical ‘bits’ of 1 and 0.  Just as a bit is the basic unit of information in a classical computer, a qubit is the basic unit of information in a quantum computer.  It takes advantage of the strange … Read more
