Orbex reveals first full-scale microlauncher rocket developed in Europe
Wednesday, 11 May 2022 08:36
Orbex has unveiled the first full-scale prototype of the Prime orbital space rocket on its dedicated launch pad publicly for the first time.
The unveiling of the first of a new generation of European launch vehicles - designed to launch a new category of very small satellites to orbit - represents a major step forward for the British rocket company as it prepares for the first ever vertica Warp speed 'Unruh effect' can finally be tested in the lab
Wednesday, 11 May 2022 08:36
A major hurdle for work at the forefront of fundamental physics is the inability to test cutting-edge theories in a laboratory setting. But a recent discovery opens the door for scientists to see ideas in action that were previously only understood in theory or represented in science fiction.
One such theory is on the Unruh effect. When astronauts in a spacecraft undergo super strong accel Keeping time with the cosmos
Wednesday, 11 May 2022 08:36
Various technologies, networks and institutions benefit from or require accurate time keeping to synchronize their activities. Current ways of synchronizing time have some drawbacks that a new proposed method seeks to address. The cosmic time synchronizer works by synchronizing devices around cosmic ray events detected by those devices. This could bring accurate timing abilities to remote sensin Unpacking black-box models

Modern machine-learning models, such as neural networks, are often referred to as "black boxes" because they are so complex that even the researchers who design them can't fully understand how they make predictions.
To provide some insights, researchers use explanation methods that seek to describe individual model decisions. For example, they may highlight words in a movie review that inf Satellite eyes pinpoint waste from space to reduce ocean pollution
