Quantum computers: Meet my new computer. Different than the old computer…
In theory, quantum computers can do anything that a classical computer can. In practice, however, the quantumness in a quantum computer makes it nearly impossible to efficiently run some of the most important classical algorithms. The traditional grade-school method for multiplication requires n^2 steps, where n is the number of digits of the numbers you’re multiplying. For…

How do we know the stars are suns? (On the limits of astronomy)
Abstract: The Sun being another star is common knowledge. However, as it happens with all things that are considered obvious, few can actually name exactly who and how the Sun was considered as just another star. It seems that besides evidence from stellar spectroscopy and the measurement of astronomical distances, philosophical principles also played a…

Causality debunked.
Researchers at the University of Vienna and the Austrian Academy of Sciences develop a new theoretical framework to describe how causal structures in quantum mechanics transform. They analyze under which conditions quantum mechanics allows the causal structure of the world to become "fuzzy." In this case, a fixed order of events is not possible. The…

Zooplankton. Light. Dark. Sun. Moon. Nothing.
The daily rising and setting of the sun propels what is thought to be the world’s largest migration: Tiny zooplankton move from the near-surface waters — where they spend the night feeding — down into deeper, darker waters during the day to avoid predators that rely on sight for finding a meal. It was thought…

Modern "civilization". Sun. Power...
Our planet, the world and we the living beings-all almost had come to an end two years ago but our Earth turned out to be fortunate enough to escape a strong and fierce solar storm. "Luckily for us, it missed our home planet. If it had hit, we would still be picking up the pieces",…
