Taking photos used to require technical knowledge and time in a lab, but now we have electronic devices in our pockets that do all of the work for us. How do these miracle devices do it? Hosted by: Olivia Gordon

Austrian physicist Erwin Schrodinger, one of the founders of quantum mechanics, posed this famous question: If you put a cat in a sealed box with a device that has a 50% chance of killing the cat in the next hour, what will be the state...

We don't think of pocket calculators as being all that special these days, but in reality their rise coincided with many of the innovations we take for granted today.

Humans have an almost insatiable energy demand, so scientists and engineers are always on the lookout for sustainable ways to provide the energy we need. And some of these ideas go way beyond solar panels and wind...

Metal excess defect due to excess cations occurs when extra positive ions (cations) are present in the crystal lattice, occupying interstitial sites to maintain electrical neutrality. To balance the excess positive charge, electrons are...
