Nanosecond Getting data even nanoseconds faster generates huge profits. So physical location of cables & towers to transmit data is critical. Being closer, UK receives US data before Europe, through undersea fibre-optic cables. Light travels 30cm / nanosecond (billionth of a second). Straight cables transmit data fastest Guessed the Word?

Flypast 10 July flypast over Buckingham Palace, 100 days after Britain’s Royal Air Force centenary on 1 April. 22 Typhoons form ‘100’ in the sky, after 3 weeks secret practice over the North Sea. Per ardua ad astra – “Through struggle to the stars”. Each plane costs £110m ($145m), and £4,000 ($5,300) to fly for 1 hour. …
Quantum bit Artificial intelligence, powered by quantum computing, is all down to 0s and 1s. A classical bit can be a 0 or a 1. A qubit can be a 0, or a 1, or both at the same time. 2 qubits can explore 4 states: 00, 01, 10, 11. A 50-qubit quantum computer can explore 1.125 quadrillion…
Infrastructure Fast, robust wifi essential for global competitiveness, but UK is 5th for broadband availability, and 17 out of 19 for updated tech. £56bn high-speed HS2 rail from London to Birmingham/ Manchester won’t deliver double the economic/ social benefits of £25bn UK-wide full-fibre broadband. The best investments may be invisible Guessed the word? Series 3…
