However, can it really "see through" 13.7 billion years of cosmic history? Where does this specific value of "13.7 billion ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

Though the days are fast ticking by, that success is far from assured. DART is the first-ever test of what NASA calls a ...

In Roman mythology, Pluto is the god and ruler of the dead. For a return mission to the dwarf planet, Howett and her ...

For decades, physicists have talked about quantum distance, a way of measuring how similar or different two quantum states are. In this strange scale, a distance of one means two quantum states are ...

Light can scatter off light, revealing ghostly particles and clues to cracking the universe’s fundamental laws. Credit: SciTechDaily.com In a fascinating dive into the strange world of quantum physics ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...

If you could sit perfectly still in a patch of space far from any stars, planets, or particles — utter emptiness — you might expect nothing at all to happen. No heat, no sound, no light. But the ...

What is enough light? The question is difficult enough but when faced with having to calculate how much LED lighting you need to create a well-lit space, it can become a bit more complicated. Whether ...

Grow lights or supplemental lighting sources are useful for starting seedlings and giving houseplants a boost. This is especially true when natural light in your home isn't very bright. But if your ...
