Pure water is an almost perfect insulator.

Yes, water found in nature conducts electricity – but that’s because of the impurities therein, which dissolve into free ions that allow an electric current to flow. Pure water only becomes “metallic” – electronically conductive – at extremely high pressures, beyond our current abilities to produce in a lab.

There are three categories of EV chargers according to their charging speed (Level 1, Level 2, and Level 3), and knowing the difference is vital for EV owners.

It’s the first time scientists have discovered an animal that doesn’t perform aerobic respiration.

One of the most popular features for Vision Pro is the ability for it to serve as an external display for your Mac. Here’s how this feature works and how to enable it on your Apple Vision Pro.

There are three ways to connect your Apple Vision Pro to your Mac in external display mode.

Cisco today announced the launch of a Webex video conferencing app designed for the Apple Vision Pro. The app is designed to provide an immersive meeting experience that fills the space around the user.

The Webex app supports Personas, allowing Vision Pro wearers to have a visual representation of themselves in video calls while wearing the headset, and it also works with spatial audio.

We present the gravitational-wave background and its properties focusing on the background from compact binary coalescences in terrestrial detectors. We also introduce the standard data analysis method used to search for this background and discuss its detectability with second and third generation networks of detectors. To illustrate, we first use simple models and then discuss more realistic models based on simulations.
